In cybersecurity, knowing the incident response plan definition is a key role in succeeding the overall security state. Understanding this is key to executing it right when an incident takes place.
So what is an incident response plan? Let us discuss what it is, why is it important, and how it works in cybersecurity.
Incident Response Plan Definition
An incident response plan is a set of measures established by an organization to address cyber security incidents. These measures are to assist in preventing, detecting, containing, and recovering from cyber security incidents.
This plan contains the necessary steps that the organization’s employees should follow during an incident. This information is crucial because it can help prevent or minimize damage to the business, reputation, and clients of an organization.
An incident response plan is an important part of every company’s overall security strategy. It is also a vital part of the business continuity plan (BCP). It is to help an organization deal with cyber security incidents properly.
Why Is It Important?
The importance of having an incident response plan can never be overstated. This is because it provides the necessary steps that the organization’s employees should follow during an incident. So these can help prevent or minimize damage to the business, reputation, and clients of an organization.
An incident response plan also helps ensure that your business will continue to operate normally even if it encounters any cybersecurity breaches. More importantly, this plan will guide you on how to respond properly if you encounter a cyber attack, malware infection, or other similar events.
Also, this increases the effectiveness of your business continuity planning (BCP) strategy. An effective BCP strategy will help your company recover faster from any cyber-attacks that you may face in the future. You can then continue your normal operation as soon as possible after recovering from the attack.
How an Incident Response Plan Works
There are four basic steps in an incident response plan. These are detection, containment, eradication, and recovery.
The first step is detection. This is the time when the computer system detects that there is a problem disrupting the systems. This is usually by a security software and other applications that help detect intrusion and malware attacks.
The next step is containment. Containment refers to the process of preventing the spread of the attack through your network. It also refers to isolating the computer or computer system where the attack is taking place. This step will also ensure that data in the compromised system will not be accessed by illicit users. It is also when you will decide if you need to call in outside assistance regarding the attack in your organization’s network and computers.
The next step is eradication. This is when you remove all traces of malware in your network and systems. This step will also ensure that any systems and networks will be cleaned up as well.
Lastly, we have recovery. Recovery means bringing all systems back to normal operations after an attack takes place in your organization’s network. You should also perform post-incident analysis at this time to find out what went wrong during the attack so you can fix it for future incidents.
