Introduction:

The internet is full of powerful hacking tools and bad guys using them extensively. If your organization has an Internet connection or one or two disgruntled employees, your computer systems will get attacked. From the five, ten, or even one hundred daily probes against your Internet infrastructure to the malicious insider slowly creeping through your most vital information assets, attackers are targeting your systems with increasing viciousness and stealth. As defenders, it is essential we understand these hacking tools and techniques. By helping you understand attackers' tactics and strategies in detail, giving you hands-on experience in finding vulnerabilities and discovering intrusions, and equipping you with a comprehensive incident handling plan, this course helps you turn the tables on computer attackers. It addresses the latest cutting-edge insidious attack vectors, the attacks that are still prevalent, and everything in between. Instead of merely teaching a few hack attack tricks, this course provides a time-tested, step-by-step process for responding to computer incidents, and a detailed description of how attackers undermine systems so you can prepare, detect, and respond to them. In addition, the course explores the legal issues associated with responding to computer attacks, including employee monitoring, working with law enforcement, and handling evidence. Finally, students will participate in a hands-on workshop that focuses on scanning for, exploiting, and defending systems.

Course Objectives:

By the end of this course, delegates will be able to:

• Apply incident handling processes-including preparation, identification, containment, eradication, and recovery-to protect enterprise environments
• Analyze the structure of common attack techniques in order to evaluate an attacker’s spread through a system and network, anticipating and thwarting further attacker activity
• Utilize tools and evidence to determine the kind of malware used in an attack, including rootkits, backdoors, and Trojan horses, choosing appropriate defenses and response tactics for each
• Use built-in command-line tools such as Windows TASKLIST, WMIC, and REG, as well as Linux NETSTAT, PS, and LSOF to detect an attacker’s presence on a machine
• Analyze router and system ARP tables along with switch CAM tables to track an attacker’s activity through a network and identify a suspect
• Use memory dumps and memory analysis tools to determine an attacker’s activities on a machine, the malware installed, and other machines the attacker used as pivot points across the network
• Gain access to a target machine using METASPLOIT, and then detecting the artifacts and impact of exploitation through process, file, memory, and log analysis
• Analyze a system to see how attackers use the malware to move files, create backdoors, and build relays through a target environment
• Run the NMAP port scanner and Nessus vulnerability scanner to find openings on target systems, and apply tools such as TCPDUMP and NETSTAT to detect and analyze the impact of the scanning activity
• Apply the TCPDUMP sniffer to analyze network traffic generated by a covert backdoor to determine an attacker’s tactics
• Employ the NETSTAT and ISOF tools to diagnose specific types of traffic-flooding denial-of-service techniques, and choose appropriate response actions based on each attacker’s flood technique
• Analyze shell history files to find compromised machines, attacker-controlled accounts, sniffers, and backdoors
