Firewall Settings Research Articles

Cyber Security Portal for Effective Management of Servers and Firewalls

The project is an innovative endeavour that tackles the difficulties associated with overseeing heterogeneous servers inside the digital ecosystem. It suggests the creation of a single, centralized interface for the real-time monitoring and management of firewall configurations, security, and server health on diverse platforms. With an all-inclusive platform, administrators may take proactive measures against new threats by integrating firewall settings seamlessly, detecting security risks, streamlining server management, and providing administrators with actionable intelligence.Beyond traditional server management, the proposed system offers a centralized hub for effective, safe, and straightforward administrative server management in multi-server environments. It increases the overall effectiveness of server administration by reducing difficulties with server management and establishing the groundwork for a strong and resilient digital infrastructure that can adjust to changing cyber security threats

Analysis of Brute Force Attacks Using National Institute Of Standards And Technology (NIST) Methods on Routers

Abstract
 The rapid development of technology, including the internet, can trigger data security issues that harm individuals, organizations, or government agencies. One type of attack often used is a Brute Force attack, which falls under the category of cybercrime. The National Institute of Standards and Technology (NIST) often analyzes digital evidence in these cases. This study analyzes Brute Force attacks using NIST methods on a router that is an additional router to the main router. On the network at the Faculty of Engineering, Universitas Muhammadiyah Magelang (UNIMMA), information about the attack and patterns used by the attacker were successfully obtained, including the IP address and time of the attack. It is concluded that the additional router is vulnerable to Brute Force attacks, and firewall settings are necessary to secure it.

IMPLEMENTASI PENANGANAN SERANGAN MAC-CLONE PADA HOTSPOT MIKROTIK DI STMIK PRADNYA PARAMITA MALANG (STUDI KASUS: STMIK PRADNYA PARAMITAMALANG)

One of the facilities that is needed is a network agency. In educational institutions such as Colleges and universities are needed to look for references as well as add insight. The technology used is one that is technology hotspot. Currently there are many hotspot technology is applied to the High School and College. However, the hotspot network mikrotik used in STMIK Pradnya Paramita Malang still experienced many problems in network security. Attacks are frequent and intrusive security network that attacks Mac Clone. Disrupt and complicate the issue of employees as well as students who have access rights legally due access rights are duplicated by users who are not responsible. Therefore, to overcome these problems built a network security by firewall settings that the filter rule and NAT. Based on test results concluded that in building a network security RouterOS hotspot using 5.18 to leave the setting on the firewall, can address the existing Mac Clone attack on STMIK Pradnya Paramita Malang. Keywords: Firewall, Hotspot, Mac Clone, Mikrotik RouterOS 5.18.

OpenWRT기반의 유무선 공유기를 활용한 다기능 웹 서버 구축

Recently the use router is to allow multiple computers by one IP can be connect to the Internet. Also, the PC or server in order to use a Web server or a print server, Web Hard, P2P should be settings. In this paper, we are building a multi-functional Web server that using a router supported OpenWRT based on network settings and firewall settings and a variety of services. A web server can be provided the Internet phone and secure multimedia service Web server router based OpenWRT may be provided through a mobile app and the PC application service.

A game inspired defense mechanism against distributed denial of service attacks

ABSTRACTGame theory offers a promising approach toward modeling cyber attacks and countermeasures as games played among attackers and system defenders. The widely accepted concept of Nash equilibrium can be used to determine the optimal strategy for all players playing the game. In this work, we demonstrate the applicability of game theory in modeling the defense against distributed denial of service attacks. In particular, we focus on attack scenarios that attempt to create congestion in bottleneck network links. We design a game model to determine the best defense strategy for the defender in such attack scenarios. In our model, the attacker uses a botnet consisting of multiple nodes to send rogue traffic in order to flood one or more links in the target network. The defender's challenge is to determine the best firewall settings to block rogue traffic while allowing legitimate traffic. We validate our game model using simulation. Furthermore, we build a comprehensive defense architecture called game inspired defense architecture and test its performance via emulation on one publicly available testbed called DeterLab. Open source software, such as Bro intrusion detection system, Dummynet network emulator, IP firewall, and Iperf network testing tool are used to build game inspired defense architecture. Our proposed defense solution exhibits promising results during both simulation and emulation. Copyright © 2014 John Wiley & Sons, Ltd.

Using Network Node Description Language for modeling networking scenarios

This paper presents an approach for designing a language for network description, leading to a Network Node Description Language (NNDL). NNDL is generic and platform independent XML based language designed to describe a complete configuration of each network node. The node description in NNDL has all necessary information for the nodes configurations, from the common IPv4 and IPv6 addressing, firewall settings, static and dynamic routing to the complete description of the network services configuration. It provides the basis for description of a wide range of virtual network laboratory scenarios. The language has been tested in a virtual network laboratory VNLab used in a university networking course. With the introduction of NNDL language, VNLab environment becomes more flexible in terms of number of available scenarios and the time needed to create and modify them. Some extensions of NNDL for documenting computer networks are also explored in this paper.
