Iptables is a flexible firewall utility built for Linux operating systems (see https://www.howtogeek.com/177621/the-beginners-guide-to-iptables-the-linux-firewall/). It is too low level, however, and, as such,

INFA 620 LAB 3 Laboratory 3 IDENTIFYING TCP CONVERSATIONS The purpose of this lab is to practice examining traffic with a display filter. Assignment: A packet trace of normal network traffic will contain more than just the packets you want to look at. You can apply a display filter to isolate conversations within the trace. For this exercise you will use a trace file of a student at

INFA 620 LAB 2 Top of Form Laboratory 2 PRACTICE EXAMINING TRAFFIC WITH A PROTOCOL ANALYZER The purpose of this lab is to practice examining traffic using a protocol analyzer and recognize a SYN attack. The SYN flood attack is one of the common Denial of Service (DoS) attacks in the Internet. In the SYN flood attack, an attacker sends a large number of

INFA 620 LAB 1 Laboratory 1 UNDERSTANDING INTERNET PROTOCOLS In order to detect or prevent network security breaches, you must understand the Internet protocols as well as the attacker does.

A firewall is usually a computer that sits on two different networks and passes allowed traffic between them, filtering out traffic that is not permitted. A firewall is the primary deterrence device used in a network.Its job is similar to a physical firewall that keeps a fire from spreading from one area to the next. The purpose of t

INFA 620 WEEK 5 DISCUSSIONAuthentication ApplicationsAn attacker, in order to harm the system, must firstly be connected to it. Besides preventing or blocking the access for unauthorized persons, the user's ability to operate in the system has to be limited according to one's job specifications. These successful restricting access techniques are based on the establishing the identity of the user and are called authentication and authorizatio
