Step 3: Remove and recover

To remove the threat and recover, the team must identify all infected hosts on the network and then must take necessary precautions to effectively stop and kill all active processes of the attacker.

All files, backdoors and malicious programs created by the attacker must be removed but saved for investigatory purposes. Sensitive data must be saved and set aside as a means of separating the "good" from the "bad." Next, teams should check all associated systems, apply patches and fixes to eliminate vulnerabilities and correct any misconfigurations to prevent subsequent similar attacks. Teams should also perform a damage assessment on each system/file and then reinstall the affected files of the entire system as needed. Lastly, infected hosts should be disconnected and quarantined for forensic analysis.

2013 was a significant year for the IT security industry, due in large part to massive attacks on companies like Target, Michaels and Yahoo. Prior to these near brand-crushing incidents, terms like "hacker," and "data breach" had yet to make their appearance within mainstream media. Security experts predict that more and more organizations will fall victim to similar attacks; hackers spend 100 percent of their time looking for vulnerabilities to capitalize on, and defenders are tasked with multiple competing priorities and need to closely protect all of their vulnerabilities. As a result, organizations must maintain vigilance against such nefarious behavior. Hexis Cyber Solutions, a provider of advanced cybersecurity solutions for commercial companies and government agencies, outlines 10 steps organizations should take to improve their response strategy and better mitigate the impact of attacks in the future.
