Full textAbstract:
Rogue DHCP server adalah salah satu pemanfaatan celah keamanan pada mekanisme konfigurasi alamat jaringan menggunakan DHCP. Rogue DHCP server memberikan konfigurasi alamat jaringan yang salah kepada client yang tergabung di dalam jaringan dengan tujuan menciptakan serangan jaringan berupa man in the middle, sehingga dapat menimbulkan ancaman terhadap privasi client yang tergabung di dalam jaringan.Penelitian difokuskan pada analisis DHCP packets seperti DHCPDISCOVER, DHCPREQUEST, DHCPOFFER, DHCPACK yang melewati sebuah Bridge Mikrotik menggunakan aplikasi Wireshark Network Protocol Analyzer sebelum dan setelah adanya Rogue DHCP server di dalam jaringan DHCP, sehingga dapat diamati bagaimana DHCP server asli dan Rogue DHCP server saling bertukar paket DHCP dengan DHCP client yang selanjutnya dilakukan analisis terhadap Rogue DHCP packets.Dari hasil analisis didapatkan informasi parameter-parameter yang terkandung di dalam Rogue DHCP Packets yang difungsikan untuk membangun sistem keamanan jaringan DHCP berupa monitoring dan pencegahan terhadap Rogue DHCP Server menggunakan DHCP Alert yang dikombinasikan dengan Firewall Filter Rule pada sebuah Bridge Mikrotik, dengan diperoleh hasil bahwa sistem dapat mendeteksi dan mencegah adanya Rogue DHCP Server di dalam jaringan DHCP berbasis IPv4.Rogue DHCP server is one of exploiting security holes in the mechanism of configuration the network address using DHCP. Rogue DHCP server provides incorrect configuration network address to a client who joined in the network with the aim of creating a network attacks such as “man in the middle”, so it can pose a threat to client privacy who joined in the network.The research focused on the analysis of DHCP packets such as DHCPDISCOVER, DHCPREQUEST, DHCPOFFER, DHCPACK which passes through a Bridge Mikrotik using Wireshark Network Protocol Analyzer application before and after the Rogue DHCP server in the DHCP network, so it can be observed how the original DHCP server and Rogue DHCP Server exchanging packets with a DHCP Client and then make an analysis of the Rogue DHCP packets.The result of analysis obtained information of parameters that contained in the Rogue DHCP Packets that enabled to build a DHCP network security system in the form of monitoring and prevention of Rogue DHCP server using DHCP Alert combined with Firewall Filter Rule on a Bridge Mikrotik, with result that the system can detect and prevent existence of Rogue DHCP Server in the DHCP based IPv4 network.

Full textAbstract:
DHCP Server as part of the network infrastructure in charge of distributing host configurations to all devices has the potential to be controlled. If the DHCP Server is successfully controlled, all network devices connected to the server can potentially be controlled. From the observations made at PT. Rekayasa Engineering found a vulnerability in the DHCP Server that has the potential to experience DHCP Rogue or DHCP Spoofing, where the client will fail to communicate with the authorized DHCP Server, as well as open the door for attackers to enter the network. For this reason, DHCP Snooping and DHCP Alert methods are implemented. DHCP Snooping will ensure that every data traffic has been filtered and directed to the registered interface. Meanwhile, the use of DHCP Alert is required in monitoring data traffic during the Discover, Offer, Request, and Acknowledge (DORA) process. In the tests performed, DHCP Snooping and DHCP Alert managed to anticipate attacks that tried to placed DHCP Rogue on the network infrastructure. DHCP Alert, configured on the proxy router, ensures that the DORA process can only occur between an authorized DHCP server and a client. DHCP Snooping test also shows that communication from clients can only be replied to by Trusted DHCP Server. The existence of DHCP Snooping and DHCP Alert makes the host configuration fully controlled by the authorized DHCP Server.

 Abstract - This journal aims to solve the problem of the DHCP server network attack method, which is a network security feature that is rarely used by people, because it is less important for network security, causing the network to pay less attention to network security problems. This journal will discuss how to circumvent DHCP servers and how to implement these security features of the network. In addition, this Paper Template is used as a guide for papers (scientific papers) for publication in journals managed by Bina Sarana Informatika. The author of the paper must follow an evidence whether the user features a DHCP server that is capable of blocking DHCP. The research used by the author is by conducting research using a simulation network because it uses a Cisco-based DHCP server, so the authors will conduct a research where the simulation network is created in a Cisco packet trecer simulation application specifically for Cisco simulations specifically for hardware. From the results of comparisons and research conclusions, an ordinary writer who does not use the rogue attack DHCP server security features can control the entire network by simply applying the IP of the DHCP server to the network. On the other hand. Networks that use DHCP server network security features are controlled by IPs that are transmitted from hackers, clients only get IPs from DHCP server officials, so that the network is safe and protected from hacker control.

Jaringan komputer memiliki kelemahan karena akses jaringan hanya diberikan melalui DHCP server. Akibat yang dapat ditimbulkan dari hal tersebut adalah terjadinya DHCP Rogue yang merupakan server palsu yang memberikan alamat gateway yang salah pada komputer client sehingga komputer tidak dapat terhubung jaringan dan internet. dengan DHCP snooping diharapkan dapat membantu keamanan jaringan internet karena akses ke IP address atau MAC address yang telah terdaftar di router dan penyerang tidak bisa masuk ke dalam jaringan tersebut. Metode penelitian menggunakan Software Cisco Packet Tracer 8.0 dengan topologi 2 buah router. Hasil implementasi didapatkan bahwa DHCP Snooping dapat membatasi DHCP Server yang tidak disetujui atau tidak diketahui untuk memberikan informasi berbahaya kepada client sehingga dapat membantu keamanan lebih baik

Setiap komputer membutuhkan dan harus memiliki IP Address untuk terhubung dengan pengguna jaringan komputer lainnya, IP Address akan dibagikan otomatis kepada pengguna jaringan menggunakan Router sebagai DHCP Server. Selain DHCP, Router memiliki layanan DHCP Accounting yang dapat meningkatkan keamanan jaringan dengan fitur AAA dan RADIUS Server yang dapat diimplementasikan dengan Freeradius. DHCP Accounting memiliki kemampuan akuntansi untuk transmisi pesan START dan STOP yang aman, namun kapasitas flash memori pada router C2691 sekitar 32 MB membuat layanan DHCP Accounting tidak akan berjalan maksimal apabila memiliki banyak user. Penggunaan MySQL sebagai database dapat menjadi solusi permasalahan ini. Pada saat menggunakan fitur DHCP Accounting, data-data dari DHCP Accounting akan dikirim dan terpusat pada Freeradius. Data accounting yang terpusat pada Freeradius akan disimpan menggunakan database MySQL sehingga ruang penyimpanan yang tersedia akan jauh lebih besar dan dapat menampung lebih banyak data dari DHCP Accounting, serta memonitoring jaringan sehingga meningkatkan keamanan jaringan bagi pengguna.

Akses jaringan Internet sangat dibutuhkan oleh setiap kalangan bahkan sudah menjadi kebutuhan pokok bagi penggunanya dalam memperoleh informasi. Semakin banyaknya pengguna internet menyebabkan keamanan jaringan sangat dibutuhkan terutama jaringan internet pada instansi besar. Dengan tersebarnya jaringan internet tersebut maka sangat berpotensi akan adanya DHCP server palsu, hal ini bisa jadi menyebabkan client mendapatkan IP address bukan dari DHCP yang sebenarnya melainkan dari DHCP Server palsu tersebut dan juga dengan penggunaan Switch yang tersebar menyebabkan switch bisa di akses oleh siapa saja yang memungkinkan penyalahgunaan port switch oleh orang – orang yang tidak berkepentingan. Karena metode untuk mencegah pelanggaran keamanan jaringan disebabkan adanya server lain yang tidak dipercaya dan untuk mencegah akses dari perangkat tidak dikenal yang ingin terhubung ke jaringan yang dapat mengakibatkan komputer client tidak terhubung pada sebuah jaringan yang semestinya jadi metode keamanan jaringan perlu ditingkatkan lagi yaitu dengan menggunakan metode DHCP Snooping client hanya akan mendapatkan Ip address dari DHCP server yang dipercaya dan metode Switch Port Security hanya mengijinkan perangkat yang Mac addressnya sudah terdaftar saja yang bisa terhubung ke Switch.

Mobile collaborative learning (MCL) is extremely recognized as focusing archetype in educational institutions. It demonstrates cerebral synergy of assorted collective minds. It handles several problems in order to motivate social activity for mutual communication. To advance and promote baseline for MCL; several supporting frameworks, architectures including number of different mobile applications have been introduced. But, no one has mainly focused to augment the security of those architectures. The paper handles issues of rogue DHCP server that highly affects network resources during MCL. The rogue DHCP is illegal server that issues the fake IP address to users for sniffing the legal traffic. This contribution specially targets the malicuius attacks that weaken the security of mobile supported collaborative framework (MSCF). The paper introduces multi-frame signature-cum anomaly-based intrusion detection system (MSAIDS) that blocks an unlawful behavior of rogue DHCP server. This novel security method emphasize confidence of users and secures also network from illegitimate interference of rogue DHCP server. Finally, paper confirms scheme through simulations. The simulations comrises of testbed, ns2 and discrete simulation.

Full textAbstract:
This work presents a strategy to scale out the fault-tolerant dynamic host configuration protocol (DHCP) algorithm over multiple interconnected local networks. The proposed model is open and used as an alternative to commercial solutions for a multi-campus institution with facilities in different regions that are interconnected point-to-point using a dedicated link. When the DHCP scope has to be managed and structured over multiple geographic locations that are VPN connected, it requires physical redundancy, which can be provided by a failover server. The proposed solution overcomes the limitation placed on the number of failover servers as defined in the DHCP failover (DHCP-F) protocol, which specifies the use of one primary and one secondary server. Moreover, the presented work also contributes to improving the DHCP-F specification relative to a number of practical workarounds, such as the use of a virtualized DHCP server. Therefore, this research assumes a recovery strategy that is based on physical servers distributed among different locations and not centralized as clustered virtual machines. The proposed method was evaluated by simulations to investigate the impact of this solution in terms of network traffic generated over the VPN links in order to keep the failover service running using the proposed approach.

Full textAbstract:
The dynamic host configuration protocol (DHCP) servers are forms of an Internet of Things (IoT) address management server (IoTAMS) that gives network configuration settings to newly connected hosts. Administrators of a network may save time by setting DHCP servers instead of every network node. However, the absence of a more robust authentication method for DHCP servers makes hosts susceptible to attacks since neither the server nor the users are able to check the other’s authenticity during DHCP connections. These concerns result in both internal and external threats to the system that have the potential to impair network services. Among these threats are malicious DHCP servers and DHCP starvation. This paper aims to provide a novel approach for tackling these issues and protect the DHCP protocol. The proposed model uses the Diffie–Hellman key exchange mechanism, the elliptic curve discrete logarithm problem (ECDLP), a one-way hash function, blockchain technology, and a smart contract. In addition, registration and validation processes provide support for the proposed model in combating DHCP risks for both internal and external system threats. Results from this study show that the proposed model has an average of 21.1% more resistance to a growing number of adversaries than the benchmark models, thus revealing that the model is better suited for the security of IoT address management servers in smart homes, thereby enhancing resilience against related threats and the success of IP address management.

Full textAbstract:
Mobile Ad hoc NETworks (MANETs) are infrastructure-free, highly dynamic wireless networks, where central administration or configuration by the user is very difficult. In hardwired networks nodes usually rely on a centralized server and use a dynamic host configuration protocol, like DHCP [Droms et al. 2003], to acquire an IP address. Such a solution cannot be deployed in MANETs due to the unavailability of any centralized DHCP server. For small scale MANETs, it may be possible to allocate free IP addresses manually. However, the procedure becomes impractical for a large-scale or open system where mobile nodes are free to join and leave.

For customers of PT. Seven Media Angkasa, which is engaged in providing fast online shopping services in Indonesia, definitely needs stable internet to process requests from customers. Even though it already has 2 ISPs, sometimes there are frequent downtimes which will disrupt the service process for customers who want to shop. In this case, one of the Load Balancing methods is the Per Connection Classifier (PCC) which is able to specify a packet to the gateway of a particular connection. Failover for backing up The weakness of the PCC method is Failover which can switch automatically if one of the systems fails so that it becomes a backup for the system that has failed. Added Telegram Bot as a DHCP Alert which can detect if there is a DHCP Rouge. By using the PCC method, it is able to maximize bandwidth usage and minimize the occurrence of downtime in sending or receiving data. So with the addition of the Failover method, if there is a temporary delay when many incoming requests can interfere with performance, Failover can move manually or automatically if one of the systems fails so that it becomes a backup for a failed system. If gateway 1 is disconnected, the backup gateway will replace gateway 1. If gateway 1 returns to normal, the connection path is used again to become gateway 1. Likewise with gateway 2 when it is disconnected. From testing on the speedtest.net tools, it was found that the Load Balancing applied was able to combine 2 ISPs into one, namely Download to 19.18 Mbps and Upload to 18.47 Mbps. The Telegram Bot is able to send notifications when there is a counter DHCP Server with the contents of the message successfully getting a Mac Address or unknown server from the counter DHCP server, namely DC: 2C: 6E: 81: CF: 34.

The impact of internet cut off or disrupted at SD Inpres Papindung, the teachers will have difficulty finding teaching materials and may have to return to traditional methods that are less effective. Updating Dapodik data will also be disrupted, which could affect school administration and evaluation. The unavailability of an internet connection does occur due to technical reasons or due to intentional elements, one of which is the use of Yersinia software. Yersinia is a piece of software that is commonly used to attack available networks by sending fake MAC addresses continuously so that the IP address on the DHCP server runs out, so that the client does not get an IP address which causes the client unable to access the internet. This attack are called DHCP Starvation Attack. This can be prevented using Bridge Filtering method. Bridge Filtering can filter only recognized MAC addresses to transmit data or can request an IP address from the DHCP server, while MAC addresses that are not recognized or foreign devices will not be allowed to request from that port or will not receive an IP address from the DHCP server. The aim of implementing Bridge Filtering is to measure the creativity of the Bridge Filtering method in preventing DHCP Starvation Attack attacks so that clients who want to connect to the network can access the internet and improve network quality at SD Inpres Papindung.The results show that the Bridge Filtering method effective in preventing DHCP Starvation Attacks and improves network quality at SD Inpres Papindung which is shown by an increase of throughput, before implementation it was 794.66 Kbps and after implementation it was 1283.70 Kbps, there was a decrease of delay from 6.89 ms before implementation to 4.06 ms after implementation. There was also a decrease in jitter before implementation 10.56 ms and after implementation 6.05 ms, but caused an increase in packet loss which was 0.30% before implementation and after implementation increased to 0.79%. Of the four variables, all of them remain at the same level except for the throughput variable, where there is a change from the fair category to the good category, so that it has an impact on the quality of the internet network at SD Inpres Papindung after implementing Bridge Filtering which is stated to be better than before implementing Bridge Filtering on the internet network at SD Inpres Papindung.

As people become more dependent on information technology, the need for Internet availability increases. Various types of devices are connected to the network, increasing the convenience of using information technology. However, this convenience can often be disrupted by attacks on the network infrastructure, one of which is a DHCP Starvation attack. The Dynamic Host Configuration Protocol (DHCP) is a client-server-based protocol used to automatically assign or obtain IP addresses for client computers or other network devices. Mitigating DHCP Starvation attacks is one form of protection for users. The impact of this attack is that the attacker can become one of the hosts on the network and perform a man-in-the-middle attack, so the impact of information leakage can occur. In addition, it is necessary to know the impact on router resources when a DHCP Starvation attack occurs, so that network managers can calculate how much resources are needed. The author uses a Filtering method based on Mac address es, ARP, and alerts on the Mikrotik router. In addition, the PPDIOO method is also used to develop this system, which consists of preparation, planning, design, Implementation, operation, and optimization. The test results showed that the application of this Filtering method proved to be very effective in preventing DHCP Starvation attacks, and the router board resources were not significantly affected when this Filtering method was applied.

Full textAbstract:
The requirement for a computer that is physically connected to a computer network to be able to access existing resources on a computer network in the form of an IP address obtained statically or dynamically. On a static IP address, there are not many problems that arise because it is loaded directly into the computer, while for a dynamic IP address, security problems arise in the form of a dynamic IP address sharing server in the form of DHCP Rogue. The configuration that is added to the first router when the network is hit by a DHCP rogue attack is to configure the main router, in this case, the first router, and the switch used as a connecting device between computers. configuration on both switches is done by snooping trust which is useful for securing IP addresses to avoid IP attackers. This research was conducted to find out if a computer network with a dynamic IP address was attacked by sending files between computers. Files with the longest sending time indicate an attack on the computer network. The method used in this study is the ANOVA test with descriptive-based analysis. Based on the results of the analysis, it is known that the average file transfer time on networks affected by DHCP Rogue is higher than the average file transfer time on normal and mitigated networks, and the significant value of the ANOVA test results has a value of 0.004. In general, it can be concluded that there are differences in data transfer when the network is normal, the network is subject to DHCP Rogue, and the network has been mitigated with DHCP Rogue.

Full textAbstract:
Penerapan otomatisasi manajemen konfigurasi jaringan dapat meningkatkan efisiensi dan meminimalkan risiko kesalahan konfigurasi. Penelitian terdahulu telah berhasil menerapkan otomatisasi manajemen konfigurasi Virtual Local Area Network (VLAN), InterVLAN dan Dynamic Host Configuration Protocol (DHCP) Server menggunakan Ansible pada infrastruktur jaringan berbasis Cisco. Namun rancangan sistem otomatisasi yang dibuat hanya dapat diterapkan pada rancangan jaringan ujicoba di penelitian tersebut. Konfigurasi kebijakannya masih dikelola secara statik dan digabungkan menjadi satu kesatuan didalam file Ansible playbook sehingga ketika terjadi perubahan harus diubah di dalam file tersebut secara langsung. Penelitian ini mengimplementasikan Ansible Playbook dengan variable files yang menampung kebijakan konfigurasi sehingga dapat mengotomatisasi manajemen konfigurasi VLAN berbasis VTP dan layanan DHCP secara dinamis. Metode penelitian yang digunakan adalah Network Developement Life Cycle. Rancangan jaringan ujicoba disimulasikan menggunakan PNETLab. Sistem otomatisasi yang dibangun dapat digunakan untuk manajemen konfigurasi perangkat jaringan baik router, switch maupun multilayer switch meliputi pembuatan dan penghapusan VLAN berbasis VTP dan DHCP di setiap lokasi. Selain itu sistem otomatisasi yang dibuat dapat mempercepat proses pengelolaan VLAN berdasarkan 3 (tiga) kali percobaan di setiap lokasi yaitu rata-rata 6 (enam) kali lebih cepat ketika operasi pembuatan konfigurasi. Sedangkan ketika operasi penghapusan konfigurasi, sistem otomatisasi rata-rata 3 (tiga) kali lebih cepat dibandingkan secara manual.

Full textAbstract:
Distributed denial of service is a form of cyber-attack that involves sending several network traffic to a target system such as DHCP, domain name server (DNS), and HTTP server. The attack aims to exhaust computing resources such as memory and the processor of a target system by blocking the legitimate users from getting access to the service provided by the server. Network intrusion prevention ensures the security of a network and protects the server from such attacks. Thus, this paper presents a predicitive model that identifies distributed denial of service attacks (DDSA) using Bernoulli-Naive Bayes. The developed model is evaluated on the publicly available Kaggle dataset. The method is tested with a confusion matrix, receiver operating characteristics (ROC) curve, and accuracy to measure its performance. The experimental results show an 85.99% accuracy in detecting DDSA with the proposed method. Hence, Bernoulli-Naive Bayes-based method was found to be effective and significant for the protection of network servers from malicious attacks.

Handoff in a distributed IEEE 802.11 Wireless LAN network is a source of significant amount of problems on the video transmission environment. The visual quality of video streaming applications is lowered when stations are in handoff status. In this paper, we introduce an architecture of a session proxy (SP), which tries to preserve the quality of the streaming video upon each handoff between access points. We have evaluated thresholds of RSSI and Loss Frame Rate (LFR) for deciding the moment when the handoff process shall begin. Our solution performance was evaluated in a testbed implementation for MPEG-4 video on demand with one video server (VLS) and two FreeBSD-based access points supporting Mobile IP, DHCP Server and IAPP approach.

Internet is a source of information which is widely used today. However, the mode of internet abused becomes more various and unavoidable. The internet abused can be done from external or internal networks. Unified Threat Management (UTM) is one of a good solution to secure the networks, because it has several security features such as firewall, proxy, Intrusion Prevention System (IPS) and several other security features in one package. Endian is an UTM distro which is an open source in large community. Besides having some security features, Endian also has some network management features such as DHCP, routing, and VPN. This research put Endian as the center of a network topology that connected to the internal network/LAN, DMZ Server, and Internet Network/WAN. The tests are conducted in the form of implementation of DHCP feature, content filtering, port restrictions on interzone, and the response of the IPS features that exist on the Endian while receiving the attack. The results showed that Endian UTM is quite well in maintaining the security of the networks.

As cyber threats become more sophisticated, traditional security mechanisms relying solely on Active Directory (AD) for authentication and authorization lack real-time threat detection and response capabilities. This project enhances security by integrating AD with Splunk, a Security Information and Event Management (SIEM) solution, within a virtualized environment where Microsoft Server 2022 hosts AD services and a Domain Controller, while Splunk provides centralized security monitoring. PowerShell scripting automates user management and event log monitoring, improving administrative efficiency. To evaluate system effectiveness, a simulated password-cracking attack from a Linux machine (IP: 192.168.10.250) targets the AD server, with Splunk monitoring security logs for real-time anomaly detection, automated threat alerts, and advanced analytics to identify unauthorized access attempts, privilege escalation, and insider threats. The network setup includes grydsecurity, featuring an Active Directory Server (192.168.10.7), a Splunk Server (192.168.10.10), and a DHCP-connected client PC, with RDP restricted on client machines to prevent remote attacks but accessible on the server for administrative purposes. By integrating AD with Splunk SIEM, this system strengthens IT infrastructure security, enhances incident response, ensures compliance with regulatory frameworks such as HIPAA and GDPR, and leverages machine learning-based detection for proactive cyber defense. This project demonstrates a scalable, intelligence-driven security model that combines automation, system administration, and cybersecurity best practices to safeguard enterprise environments.

Cloud Computing is advanced technology for resource sharing through network with less cost as compare to other technologies. Cloud infrastructure supports various models IAAS, SAAS, PAAS. The term virtualization in cloud computing is very useful today. With the help of virtualization, more than one operating system is supported with all resources on single H/W. We can also say that we acquired single server but we used it for multiple functions(Web Server, database server, Application Server, DNS Server, DHCP Server). One more asset of cloud computing is Multi Tenancy. Sharing of one database to many tenants or we can say users is known as multi tenancy. Cloud computing customize the requirements of user and u r able to pay as per use. Network applications share through multi tenancy for various users but security of data is basic issue. This paper discusses about the security with more encryption routines and upgrades performance with network route optimization.Due to increase in performance and security, more number of people attract towards CLOUD COMPUTING. Virtualization is a term of cloud computing. Virtualization is a very new technology in computer technologies. With the help of virtualization share the resources software and hardware. Best example of virtualization is THIN CLIENT technology, which runs more than one client with one server. Desktop virtualization shares the desktop with other thin client.

DoS (denial of service) assault is the most prevalent assault these days. It imposes a major risk to cybersecurity. At the point when this assault is propelled by numerous conveyed machines on a solitary server machine, it is called as a DDoS (distributed denial of service) assault. Additionally, DoS bypass on DHCP (dynamic host configuration protocol) server assault is a rising and famous assault in a system. The authors have proposed a stochastic intrusion detection game-based arrangement utilizing controlled Markov chain that figures the transition probabilities starting with one state then onto the next in a state transition diagram. At first, the authors have conjectured these assaults, and after that, they proposed a methodology that uses the idea of master and slave IPS (intrusion prevention system). This approach works well when mapped to these estimated assaults and accordingly helps in the recognition and counteractive action of these assaults in a cloud domain.

Test results are retrieved at regular intervals from the BioLinkTMLIS (Laboratory Information System), encrypted and transferred to a secure area on the Web server. The primary health-care centres dial into the Internet using a local-cell service provided by Polish Telecom (TP), obtain a TCP/IP address using the TP DHCP server, and perform HTTP ‘get’ and ‘post’ operations to obtain the files by secure handshaking. The data are then automatically inserted into a local SQL database (with optional printing of incoming reports)for cumulative reporting and searching functions. The local database is fully multi-user and can be accessed from different clinics within the centres by a variety of networking protocols.

IP addressing with DHCP server, for testing scenarios using UDP protocol packet delivery with packets sent at 1000 Bytes, the number of packets sent is 100 packets/s, then given background traffic variations of 50 Mbps, 100 Mbps, 150 Mbps and 200 Mbps to networks that have two different link bandwidth values as a comparison for analyzing the results of testing the QoS parameters, which are 100 Mbps and 200 Mbps. The test results are obtained when background traffic exceeds the link bandwidth capacity, the resulting throughput will be smaller on the destination side by 485.64 Kb/s, delay increases by 240.21 ms, then for jitter by 2.48 ms, resulting in overload resulting in packet loss of 37.41%. However, when background traffic increases and does not exceed the specified link bandwidth capacity, the overall QoS parameter value is generated in the good category, namely throughput of 774.42 Kb/s, delay of 0.41 ms, jitter of 0.37 ms and packet loss of 0.00%.

ZTP (Zero Touch Provisioning) adalah sebuah inovasi dalam dunia IT, yang merubah cara melakukan konfigurasi perangkat yang sebelumnya manual menjadi otomatis. Inovasi ini tercipta dikarenakan semakin banyaknya kebutuhan akan perangkat jaringan. Tantangan tersendiri bagi perusahaan jaringan untuk mengelolanya baik dari sisi waktu dan biaya. Pada metode tradisional, Administrasi perangkat jaringan harus masuk ke setiap perangkat jaringan satu persatu untuk melakukan konfigurasi. Hal tersebut tentunya tidak efisien. Disinilah kelebihan dari otomasi, konfigurasi perangkat jaringan menjadi lebih efisiensi, ditambah pekerjaan yang sifatnya repetitive seperti backup konfigurasi, monitoring, bisa dilakukan dengan otomatis. Pada penelitian ini penulis akan menguji sebara efisien penggunaan dari ZTP dengan cara membandingkan waktu konfigurasi dengan cara manual dan otomasi dengan ztp. Konfigurasi yang akan di lakukan pada penelitian ini adalah konfigurasi IP Address, membuat DHCP server, dan membuat hotspot pada MikroTik. Untuk memudahkan melakukan manajemen jaringan penulis membuat dashboard untuk mengetahui perangkat mana yang sudah dikonfigurasi. Sistem otomasi sendiri dibuat dengan menggunakan pemrograman Python yang memanfaatkan library utama Paramiko sebagai penghubung antara perangkat jaringan dengan server otomasi melalui protokol SSHv2.

Full textAbstract:
Autoconfiguration in mobile ad hoc network (MANET) is a challenging task to be accomplished in hostile environment. Moreover, a mobile node in MANET is usually configured with a unique IP address for providing better communication and to connect it with an IP network. Essentially, the nodes in wired networks are autoconfigured using a commonly known Dynamic Host Configuration Protocol (DHCP) server. However, MANET exhibits the intrinsic characteristics (i.e., distributed, dynamic and multi-hop) in nature; hence, it is hard to adopt DHCP server for autoconfiguration of nodes in MANET without applying significant modifications in auto-configuration scheme. This paper proposes an efficient IPV6 Duplicate address Elimination Autoconfiguration protocol for MANETs (IDEAM) which comprises the member and the cluster head (CH) nodes organized in a hierarchical fashion. Further, the proposed protocol considers the global connectivity exhibiting reduced communication overhead among the nodes. Initially, our proposed auto-configuration protocol encourages the Duplicate Address Detection (DAD) operation by selecting a controller node from the prefixed group members using a joining node in the network. In other words, the DAD operation is performed perfectly by a selected controller node on behalf of the new joining node. Thus, our proposed protocol becomes more effective and behaves better in the minimization of overhead by considerably eliminating the DAD messages broadcast in the network. Also, we imposed a new Flower pollination based gray wolf optimization (FPGWO) algorithm for selecting an optimal header among the group members by considering various node parameters (i.e., node location, resources and node density) to avoid unnecessary broadcasting of additional weight messages about each node in the network. The simulation results proved the efficiency of our proposed protocol in terms of scalability and in the minimization of overhead. Also, an effectual method provided by our proposed approach enhances the activity of marginal nodes over the group for healing the network that degrades its performance followed by the splitting and merging operation.

Full textAbstract:
Quality of Service (QoS) on Live Streaming has the main parameters, namely bandwidth, jitter, loss and delay, which are measured on the implementation of Wireless IP Camera based on Android Smartphone. The test tools used iperf and ping software, to capture data packets. The network design in this study uses Xonz Wireless IP Camera, wifi router, Server/Laptop and Android Smartphone to monitor or access the services provided. Surveillance/reconnaissance or surveillance by accessing live streaming can be done from anywhere as long as there is still an intranet network. wifi router provides DHCP service, Server/Laptop provides a Virtual Machine using MS Windows Server 2003 Operating System. Web Server is not installed on Real Machine but on Virtual Machine. The smartphone used has the Android Operating System version 4.4.2. IP Camera Xonz model XZ-12Z-HR/W has one major drawback that it can only be accessed via Internet Explorer Browser which can only run on MS Windows Operating System. Some applications that are already available on Google Play and installed on Android Smartphones cannot detect the Wireless IP Camera. The outcome or impact of this research is the creation of a simple Live Streaming application that can be accessed by all browsers on all platforms including Android Smartphones. Measurements were made using iperf and ping. The results showed that the Xonz IP Camera can still be used for mobile room monitoring as far as a maximum of about 20 m from the wifi router and still meets the standard QoS values set by TIPHON and ITU-T G.114.

Virtualization technology has helped companies consolidate various server roles into a single physical server, reducing hardware costs. Hypervisor is a software in virtualization that is used to manage server hardware, allowing multiple Virtual Machines (VM)/Containers (CT) to run on a single physical machine. Companies face various challenges to remain competitive in the digital era, such as the need for rapid deployment of virtual guests and virtual networks on hypervisors in development, testing, and production environments, as well as securing network services. The purpose of this study is to implement SDN on hypervisors to centrally control virtual network configurations with a simple design, reducing setup and maintenance costs and time. In addition, it also implements a firewall and Virtual Private Network (VPN) based on OpenVPN and a reverse proxy to secure the hypervisor and VM/CT so that services remain available. This study presents a new approach that integrates Software-Defined Network (SDN)-based network management with comprehensive security solutions on hypervisors. This approach combines efficiency in network management and security that have rarely been focused on simultaneously in previous studies. The research method uses the Network Development Life Cycle (NDLC). The hypervisor used is Proxmox Virtual Environment (PVE) which is installed on the Virtual Private Server (VPS) provider IDCloudHost. Based on the results of the trials that have been carried out, it can be concluded that the simple zone type SDN on PVE can be used to control network configurations centrally and more simply such as routing, Dynamic Host Configuration Protocol (DHCP), Source Network Address Translation (SNAT), hostname registration and Internet Protocol (IP) from CT to forward lookup zone on the Domain Name System (DNS) server. Activating the firewall and creating rules at the cluster and CT levels from PVE and OpenVPN can protect the infrastructure when accessed both internally and externally. While the implementation of nginx reverse proxy can secure access to HTTP/HTTPS services on CT in PVE.

Abstrak: Membangun sebuah jaringan komputer merupakan hal yang cukup penting di masa sekarang, agar mempermudah segala aktifitas sharing data secara efisien dan cepat. Komunikasi dengan mitra kerja pada SMK Bina Putra masih dilakukan dengan bertemu secara offline, hal ini kurang efektif mengingat jaman sekarang sudah memiliki berbagai macam teknologi yang bisa dimanfaatkan. Terlebih lagi pertemuan langsung itu membutuhkan waktu dan biaya lebih, oleh karena itu penyampaian informasi yang lebih efisien sangat diharapkan pada saat ini. Arsitektur jaringan yang digunakan SMK Bina Putra saat ini adalah sistem operasi jaringan model LAN (Local Area Network). Sistem operasi jaringan LAN membuat user dapat terhubung satu sama lain jika sudah terkonfigurasi alamat IP nya, serta terhubung dengan router dan switch. Metode penelitian yg penulis lakukan dengan metode obsevasi, wawancara dan studi pustak sedangkan Metode analisa kebutuhan yang digunakan adalah Network Development Life Cycle (NDLC). Hasil dari penelitian ini dengan menggunakan winbox admin dapat mengkonfigurasi VPN server dan client. NAT digunakan agar PC bisa mengakses internet jika sudah terhubung dengan router utama. Setelah jaringan usulan ini di implementasikan maka kedua pihak dapat sharing data dan informasi tanpa perlu melakukan pertemuan offline.

 Abstract: Building a computer network is quite important today, in order to facilitate all activities to share data efficiently and quickly. Communication with work partners at SMK Bina Putra is still done by meeting offline, this is less effective considering that nowadays we already have various kinds of technology that can be utilized. Moreover, these meetings require more time and cost, therefore more efficient information delivery is expected at this time. The network architecture used by Bina Putra Vocational School today is a LAN (Local Area Network) network operating system. The LAN network operating system allows users to connect to each other if the IP address is configured, as well as connect to routers and switches. The research method that the author uses is observation, interviews and library studies, while the needs analysis method used is the Network Development Life Cycle (NDLC). The results of this study using winbox admin can configure the VPN server and client. NAT so that the PC can access the internet if it is connected to the main router. After this proposal network is implemented, the two of them can share data and information without the need for offline meetings.

Full textAbstract:
PT. St. Morita Industries has a Wireless Local Area Network (WLAN) which is used as a medium for exchanging data and information by utilizing wireless transmission media, WLAN currently uses WPA2-PSK as a security system to authenticate users to access the internet. However, the use of WPA2-PSK as WLAN security still has a weakness due to the use of the same 1 password for many users in order to connect to the WLAN hotspot will be an opportunity for cyber crime. This happens because it will be very easy for irresponsible users to enter the WLAN. Therefore, in this study, captive portal authentication will be applied as an effort to increase WLAN security replaces WPA2-PSK. This research process uses the Network Development Life Cycle (NDLC) method. All the configurations needed to build the captive portal authentication take advantage of the Winbox program. This research has resulted in a special user authentication limitation for users who have registered on the WLAN is permitted to access this company's internet. In addition, the Winbox program can also be used for monitoring all users connected to the WLAN, both active and inactive users. By setting up captive portal authentication on a WLAN network using a proxy routerboard device which comprises an IP address, DHCP server, hostpot setup, NAT firewall, and DNS server one can create a WPA2-PSK security system. This configuration is completed with the aid of the Winbox v3.37 software.
