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
