  • 1 Introduction
    Technical report, IDE1202, February 2012 Enhancing Network Security in Linux Environment Master Thesis in Computer Network Engineering By Ali Mohammed, Sachin Sama and Majeed Mohammed School of Information Science, Computer and Electrical Engineering Halmstad University i Enhancing Network Security in Linux Environment Master Thesis in Computer Network Engineering School of Information Science, Computer and Electrical Engineering Halmstad University Box 823, S-301 18 Halmstad, Sweden February 2012 ii Preface First of all, we would like to express our sincere gratitude to our Supervisor Philip Heimer and Professor Tony Larsson for their supervision and assistance in the entire thesis work. We are also thankful to IDE department, Halmstad University for providing this opportunity to complete this thesis. Ali Mohammed Sachin Sama Majeed Mohammed iii iv Abstract Designing a secured network is the most important task in any enterprise or organization development. Securing a network mainly involves applying policies and procedures to protect different network devices from unauthorized access. Servers such as web servers, file servers, mail servers, etc., are the important devices in a network. Therefore, securing these servers is the first and foremost step followed in every security implementation mechanism. To implement this, it is very important to analyse and study the security mechanisms provided by the operating system. This makes it easier for security implementation in a network. This thesis work demonstrates the tasks needed to enhance the network security in Linux environment. The various security modules existing in Linux makes it different from other operating systems. The security measures which are mainly needed to enhance the system security are documented as a baseline for practical implementation.

  • Access Control Framework
    This material is based on work supported by the National Science Foundation under Grant No. 0802551 Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author (s) and do not necessarily reflect the views of the National Science Foundation C5L1S1 When working for an institution as a Linux Administrator, you may be required to protect certain information based on its sensitivity. For instance, most organizations will have an internal network in which data contained in certain directories or drives are made public—employees can access the contents. However, certain kinds of information such as employee salaries, classified research, secret prototypes, health information, military secrets, and private communications are considered highly sensitive and are usually restrictedU the from everyone except very few people authorized to access the data. In this lesson, we will explore processes, tools, and control lists that make it possible to limit access to sensitive data on a Linux-based system. Understanding this topic is important for any system administrator configuring systems in the workplace that require access control mechanisms. C5L1S2 You should know what will be expected of you when you complete this lesson. These expectations are presented as objectives. Objectives are short statements of expectations that tell you what you must be able to do, perform, learn, or adjust after reviewing the lesson. Lesson Objective: U the Given the need to secure a Linux server, the student will recommend a set of standard Linux tools such as PAM, Access Control Lists, and TCP Wrappers to effectively secure a Linux system and demonstrate the use of one set of tools for system lock-down.

  • My Name Is Robert Kudyba and I Am the System Administrator for The
    My name is Robert Kudyba and I am the System Administrator for the Department of Computer Science here at Fordham University and a recent graduate of the Master’s in Cybersecurity. The lab will require you to install VirtualBox with Ubuntu preferable from osboxes.org. The commands listed in the lab will assume you have installed this image. Any Ubuntu version will work but if you installed from ubuntu.com then you will have to substitute the username you created for every place I reference osboxes. If you use Kali, you will be using the root user and there may be other issues as I’ve only confirmed everything works on Ubuntu. 1 In this lab, I will be gong over Linux remote access protocols Telnet and SSH, providing a history, the various encryption methods used, the concept of security through obscurity, a program called Fail2ban, how to use a Certificate Authority in OpenSSH, TCPWrapper, and Port Knocking. 2 • Telnet is a simple, text-based network protocol that is used for accessing remote computers over TCP/IP networks like the Internet. Telnet was created and launched in 1969. • Prior to telnet, you had to physically walk to a server in order to access its data. This meant, among other things, that you had to spend some time arriving at the server's location and then you had to wait for your turn to work with the server. Even if the server had the hardware power to do multiple things at the same time, you were blocked from using if someone was before you so you had to wait for others to finish their work first.

  • Firewalls and IDS
    Firewalls and IDS Dr. Natarajan Meghanathan Associate Professor of Computer Science Jackson State University E-mail: [email protected] Firewalls • A firewall is a device that filters traffic between a “protected” or inside network and a “less trustworthy” or outside network. • A firewall is basically an executable code run on a dedicated computer. • As all traffic should pass through the firewall, it is not a point of bottleneck for system performance and hence non-firewall functions are not performed on that machine running the firewall. • Also, since non-firewall code does not exist in the computer, it is hard for an attacker to make use of any vulnerability to compromise the firewall. • Design idea: – Firewalls implement a security policy that is specifically designed to address what bad things that should not happen in a “protected environment” – Security policies that dictate what to allow: Standard security practices dictate a “default-deny” ruleset for firewalls, implying that the only network connections allowed are the ones that have been explicitly stated to be allowed. – Security policies that dictate what not to allow: Users and business community who lack such a detailed understanding to explicitly state what should be allowed in prefer a “default-allow” ruleset, in which all traffic is allowed unless it has been specifically blocked. – Even though this configuration is relatively more prone to inadvertent network connections and system compromise, it is more commonly used because of mere lack of knowledge and new applications that come into existence. Firewalls • Not all firewalls need to have the same capability. • One cannot compare the “goodness” of two firewalls based on the security policies they are configured with.
