Cyber attacks are inevitable for businesses. Data can be stolen, systems can be compromised, and the reputation of the company can be damaged. If your business is hit with a cyber attack, it is important to have a plan in place for how to respond. In this blog post, we will discuss six steps for successful Incident Response Plan. By following these 6 steps, you can always be one step ahead of the game.
The first step in incident response is preparation. This means having a plan in place for how to respond to a cyber attack. The plan should include who should be notified, what steps need to be taken, and what resources are available. By having a plan in place, you can ensure that everyone knows what to do in the event of a successful cyber attack. It consists of bringing the Cyber Security Incident Response Team (CSIRT) into the capability of properly launching any incident response and being comfortable at working on it.
It implies:
The second step in incident response is identification. This is when an incident is discovered or reported to the Cyber Security Incident Response Team (CSIRT). In this phase, several actions are done here, in particular:
The third step in incident response is containment. This is when the Cyber Security Incident Response Team (CSIRT) takes action to contain the incident and prevent it from spreading as well as limiting the current damage and preventing any further damage.
The first step of containment is to isolate any networks so the hacker cant communicate anymore with the compromised network. The second step is create backups and evidence, in the case of further investigation. The final step includes fixing any affected systems such as patching any vulnerabilities and getting back online, ready to move to the next phase.
This step makes sure to remove any aftermath of the cyber attack and ensure it cannot happen again. As well as changing passwords, applying security fixes and patching all systems, the recommended way here to eradicate all badness from the incident is actually to fully reinstall systems that have been affected and immediately have the latest security fixes deployed to it.
After patching and recovering all systems, it’s crucial to get all programmes back up and running. In many cases, it might mean re-installing all systems and changing all employee’s passwords, doing whatever possible so to avoid this incident again. Careful monitoring needs to be defined and started here, for a defined period of time, to observe any abnormal behaviour.
The final step, and one of the most important, is to document everything that happened during this incident. This will help to improve the security posture and learn from any mistakes made. It includes a full analysis of what went well and what needs to be improved for future reference.This also might help in training new members of staff who join the company. All documentation written during the incident should be completed, and answer as many questions as possible regarding the what-where-why-how-who questions. Every incident should be seen as an opportunity to improve the whole incident handling process in the company.
