Enterprise Intrusion Analysis (SC-375)

Overview:

The Enterprise Intrusion Analysis course provides students with the skills needed to discover and analyze enterprise intrusions in a UNIX environment.

Description:

Who Can Benefit
Students who can benefit from this course are systems administrators and security administrators who are responsible for detecting and analyzing enterprise system intrusions. 
 

Prerequisites
To succeed fully in this course, students should be able to:
Demonstrate basic UNIX system and network administration skills
Demonstrate a basic understanding of Transmission Control Protocol/Internet Protocol (TCP/IP) networking
Demonstrate an intermediate understanding of network services: DNS, DHCP, SMTP, HTTP, and firewalls 
 

Skills Gained
Upon completion of this course, students should be able to:
1. Detect an enterprise system intrusion
2. Analyze a compromised system for crucial information: attack time, attacker location, attcker modifications to the system
3. Corrolate multiple log files from different parts of the enterprise to determine attacker usage
4. Conduct an audit of file systems to determine attacker modifications
5. Describe modern attacker methodology with proof of concept examples
