Incident Response describes the organized preparation for and response to a security incident, including identification, assessment, containment, removal, and recovery. This includes a series of steps that need to be taken to reduce the harm and get everything back to normal.
Well Coached Steps of Incident Response
Preparation:
Implement an incident response plan
Conduct training of employees on incident response protocols.
Open lines of communication.
Determine important parties involved, and understand what role they play.
Detection and Analysis:
Surveillance systems for hacker signs.
Examine security logs and alerts
When conducting forensic analysis, determine extent and magnitude of incident.
Containment:
To prevent further damage, isolate infected systems.
Remove infected devices from the network.
Set up alternative defenses to drag the threat containment.
Eradication:
Eliminate malware and such other unnecessary software.
Update systems and patch vulnerabilities.
If the compromised system has been suitably cleaned, restore them.
Recovery:
Recover any compromised systems and data.
Try out the individual feature of the system to check if everything is working fine.
Lessons Learned:
Follow up with a postmortem to determine lessons learned
Review Incident Response Plans and Security Policies
Share what you learned with employees.
Incident Response Guidelines and Practices
Prevent Security Audits: Schedule regular security audits to identify vulnerabilities.
HR Training: Train employee about security and security best practices.
Incident Response Plan: Establish a robust incident response plan.
Implementation of Strong Password Policies: Strong password policies and multi-factor authentication should be implemented.
Network Segmentation: Segment networks to reduce the scale of a breach.
Scheduled Backups: Keep a scheduled backup of important data.
Incident Response Plan- Create a team that specializes in incident response.
Communication — one can not stress enough that it is important to keep talking with the stakeholders at the needful time.
Real-time Monitoring: Monitor networks and systems for threats in real-time.
With a proper incident response plan and best practice implementation, organizations can limit the damage of cyberattacks and safeguard their most significant assets.
