Understanding the Incident Response Process with CompTIA Security+
Incident response is not an isolated event but a complete process essential to address security issues with a holistic approach. For incident response process to be successful, it is mandatory for the response teams to follow an organized approach to address an incident. The CompTIA Security+ certification concentrates on incident response, as it is one of the primary responsibilities of system security engineers and professionals.
The Incident Handling Process
The incident response and handling process revolve around:
·Preparation: The first step of an incident handling process calls for an effective plan. To address security issues successfully, the incident response team must ensure that the finalized plan is properly communicated to teams and well-documented with official guidelines to successfully address security issues and incidents.
·Incident Identification: This phase focuses on monitoring the security events to detect and identify security issues. Any alert or detection of an issue must be immediately reported. Monitoring activities include the in-depth survey of the environment and network security components such as firewalls and intrusion prevention systems. Analysts are supposed to raise an incident ticket, document the initial findings, and assign the ticket to concerned team members.
·Incident Analysis: This phase of the incident handling process requires the maximum concentration of the incident handling team. It includes resource utilization for data collection and the use of tools to analyze the potency of the detected security threat. Individual team members should have in-depth skills and a detailed understanding of live system responses, memory and malware analysis, digital forensics, and much more. This stage involves:
o Endpoint Analysis
o Binary Analysis
o Behavioral Analysis
o Static Analysis
·Eradication and Recovery: This crucial stage requires security professionals to address the actual issue, eradicate it completely, and restore the normal functioning of the enterprise. Success at this stage is dependent on the compromise indicator information gathered during the incident analysis phase. You have the capability to execute a coordinated shutdown of the figured devices, wipe the infected devices, and then rebuild the system. After this, the organization can resume normal operations.
·Post-Incident Activity: Post-incident activities play an important role in preventing similar issues in the future. This stage requires the compilation of an entire incident report, the close monitoring and observation of the system to avoid reoccurrence of the incidents, updated threat intelligence feeds, and the identification of preventive measures. The most important step is to record the lessons learned during the incident handling that help organization to modify their security policies and guidelines for better response to security issues.
