Infosec’s Incident Response and Network Forensics Boot Camp covers the essential information you need to properly detect, contain and mitigate security incidents. You’ll learn the ins and outs of incident response as well as the tools used by incident responders on a daily basis. You’ll gain hands-on experience in how systems are compromised and what traces are left behind by attackers on the network, on disk and in volatile memory.

Security incidents are a way of life in the modern world, and how organizations respond to them makes a massive difference in how much damage is ultimately done. This boot camp addresses cutting-edge attack vectors as well as tried-and-true methods for compromise. You leave with the knowledge of how to prevent incidents and the skills to defend against a security incident if it does happen.

This boot camp focuses on teaching you the five key incident response steps:

1. Plan – Preparing the right process, people and technology enables organizations to effectively respond to security incidents
2. Identify – Scoping the extent of the incident and determining which networks and systems have been compromised; includes assessing the extent to which systems have been compromised
3. Contain – Prevent the incident from further escalating using information gathered in the previous stage
4. Eradicate – Remove intruder access to internal and external company resources
5. Recover – Restore fully operational system capability and close out incident
