Many business organizations today may not be careful enough when it comes to their cyber security. This makes them susceptible to network problems like being exposed to cyber attackers and having their information stolen as a result of a breach in their network. During any form of cyberattack, a decent amount of data may be lost and if you do not have an IT team that is equipped with the knowledge of data recovery, you may lose the information forever.
It is very pertinent to have a system incidence response plan to prepare you ahead of data loss. Several techniques are used by the forensic team to help you track who compromised your company’s system and these methods are also used to prevent such system breaches from taking place again. The seven phases of incident response are seen below.
What is an Incident Response Plan?
An incident or cyber security response is a plan that is carried out immediately on your business’s system when there has been an event of a security breach. It is a brief, and straight-to-the-matter record in a document that accounts for the response plan of action to be implemented by the information security team, and incident response team as soon as there has been a cyber attack or ransomware on your business network. Also, the plan normally enlists key roles and accountability of the executive management and team members in your organization, who may have been connected one way or the other during the event.
The 7 Phases of Network Incident Response
Whether you have a small business or a large one, you must take it seriously by always getting yourself armored for any cyber security events. How you handle your company’s security situation can matter in your data recovery, if you have currently lost your data to cyber attackers. Preparation is entwined with identifying the beginning of a cyber event, how to fully recover your information, and creating a stable and highly principled security policy, which may include the following:
- Caution banners
- User privacy anticipation
- Laid out principles for event notification processes
- A well-structured incident containment conduct
- A list of tasks for structural incident handling
- Make sure there is an up-to-date corporate disaster restoration plan
- Ensuring an active security risk assessment.
2. Identifying the Problem
This stage of incident response is about identifying which cyber security has been compromised or the event that has occurred. The most important thing is to identify the network breach at the time of occurrence, which helps in guiding the cybersecurity quick response team in the right line of action. The phase involves assessing the current cyber incident and getting to know if the attack is real and how seriously it has affected your company.
After filtering all manner of false positives, and knowing the real problem, identify the aspect of your business that has been breached. This helps to know the exact damage the cyber event has caused after which, it will be easy to categorize the network security incident according to the kind of attack done on your system.
3. Containing the Situation
The next phase of incident response is controlling the situation or the attack that has affected your business data. First set up a strategy that you will use to containing the network incident from blowing out of proportion. You cannot save the day by just deleting everything in your system since you may stand more loss by deleting very important evidence while doing so.
Instead of deleting everything without control, ensure that you take both long and short-term plans of action into consideration if you must contain the situation, without escalating the problem. In this phase, you can discuss crucial aspects such as what data backup process you have prepared for implementation and what should be taken offline in the case of a system breach.
In incidence response, this phase works by eradicating the cause of cyber security breaches. So, after you have contained the situation and understood the fundamental cause of the problem, you can then look for ways to eliminate it. Even though it is important to securely eradicate the malware, at this stage, you can also pay special attention to fixing vulnerabilities and installing up-to-date software versions.
After the malware and all other problems have been eradicated, and the vulnerabilities fixed, you can now move to the recovery phase. This stage is focused on getting your system ready to operate fully and completely. You can check the systems from time to time to ensure that they have been properly fixed and everything is operating as it should.
6. Lessons Learned
Having gone through a cyber breach on your system, there are certain things you will learn, which in turn help you to avoid future happenings. So, during an incident response planning, you can reflect, and evaluate how you were able to handle the situation. In this phase of incident response, you should be ready to ask yourself if your workforce behaved with precision and agility and if you have also accessed the role of your decision.
7. Test to Develop Muscle Memory
Now that you have successfully overcome a severe security incident, it is good to celebrate but, while getting excited, do not forget that cyber attackers will always try to invade your privacy. This is why you must get ready to defend yourself as they may launch a more serious attack as soon as you have recovered. From time to time, test and repeat your incident response actions just so that you can check for signs of cyberattacks.
Understanding the seven phases of incident response, and implementing them can help you overcome your cyber security situations. First, you must prepare for the worst cyber events in your company, find out the problem areas, contain the problem, eradicate it, recover lost data, and repeat the test occasionally just to make sure your company’s system is safe and fully protected.
