A standard incident response plan consists of six structured phases that are defined by frameworks like NIST and SANS. However, plans vary by organisation, but the framework and phases are similar. The phases of incident response lifecycle are systematically designed to mitigate risk of recent ransomware attacks.

Phases of incident response to safeguard yourself from recent ransomware attacks!

1. Preparation

This fundamental phase includes establishing policies and procedures before anything goes wrong. During preparation, organisations define roles and responsibilities. A well-prepared response plan helps streamline the response process.

2. Identification

First, you must spot unusual activity or system alerts. Confirm whether it is a real incident. Also identify how bad the problem is. The identification phase is important for taking effective next steps.

3. Containment

Once a team finds an active threat, the priority shifts to containment. This Phases of incident response prevents the attack from spreading further into the network, which could cause additional damage. It is generally split into two stages: short-term containment and long-term containment. Short-term containment means taking immediate action to stop further damage, such as isolating the system from the network, while long-term containment means keeping business functions running safely.

4. Eradication

Eradication means eliminating the incident's root cause. The phase ensures that the attacker no longer has a foothold in the system. The process includes malware removal, such as deleting malicious code and scripts. It also includes fixing the security flaws that allowed the initial breach.

5. Recovery

It is also an important phase of the process. It involves safely restoring affected systems. The main goal is to return to normal business operations without any secondary incidents. The process includes restoring from backups so compromised systems can be rebuilt from clean backups.

6. Lesson learned

Although many organisations see it as unnecessary, in reality it is the most important phase. It makes an organisation stronger after a breach. It focuses on documentation and improvement.

Conclusion

An incident response plan is a structured roadmap that organisations use to detect and respond to cyberattacks. The phases above are the most important, and following the sequence is key to creating an effective response plan to safeguard against recent ransomware attacks.
