Steps For A Security Incident Response

Incident response isn’t an isolated event, it is a process. It not only involves the action of tracking who is breached the computer, but also prevents it from occurring again. For an effective incident response, the incident handling teams should follow a coordinated as well as organized procedures to any incident.

Here are six essential incident response steps, which every response process should cover to efficiently address the broad range of security incidents, which an enterprise could experience.

If an organization doesn't possess a computer forensics or incident response team, the information, which is being targeted by the hacker might be lost forever. Moreover, there is no way to determine who stole it.

Six steps for a security Incident response

1. Preparation

2. Identification

3. Containment

4. Eradication

5. Recovery

6. Lessons Learned

1. Preparation

This phase involves guaranteeing you possess the appropriate policies, response plans, call trees as well as other documents, which have been determined by the member of the incident response team. They should focus on both the external and internal entities.

4. Eradication

In the eradication phases, the importance involves guaranteeing that the organization possesses a clean and prepared system which is ready to restore. The action included here may be an entire re-image of a computer or system and the restore from the best backup.

5. Recovery

At the recovery phase, the process of determining when to fetch the computer back into production is carried out. This stage also involves determining how long the system need to be monitored for any signs of an abnormal situation.

6. Lessons Learned

The last stage of security incident response is lessons learned. This involves looking back and learn a lesson from the previous incident handling activities. This will support to integrate additional knowledge and activities back into the incident response process in order to prepare for future outcomes with additional defenses.
