6 Phases of Incident And Response | Brief Descriptions

Technology and its loopholes are always developing and changing. As a result, it is critical for every company to stay updated in order to continue to expand. At the same time, it is essential for firms to develop risk-mitigation strategies. Cybercrime incidents are increasing all over the world. Cyber-attacks are growing increasingly dangerous. Consequently, any company that wants to keep its data secure and safe should concentrate on developing a security incident and response plan.

In this post, I am going to discuss each phase of the incident response plan. Let’s start with them one by one:

Phases of Incident & Response:

1. Preparation:

In the case of a cyberattack, incident response teams must perform flawlessly, which involves robust preparation. The corporate security policy includes security violations consequences, reasonable use of company data, and definitions of a security incident.  Organizations need a proper guide on how incident response team reacts, including internal and external communication and documentation.

2. Identification:

Identification includes the detection of harmful activities. The detection of malicious activities is based on insider information, security, monitoring tools, and publicly available threat information.

3. Containment:

Containment is divided into forms short and long durations. Long-term containment restores all systems to production while removing the accounts and backdoors that caused the attack. By implementing an immediate response, short-term containment prevents the threat from expanding and causing further damage. All affected systems are also backed up by short-term confinement for later investigation.

4. Incident Removal:

The incident removal part includes evaluating the scope of the incident, identifying the point of attack, and removing any residual back-door access. During this phase, cyber security incident response teams remove remainders of an attack.  Additionally, they discover the incident’s root cause and eventually how it was carried out in order to prevent future attacks.

5. Recovery:

In this phase, the testing of the fixes from the containment phase transit to normal operations. During this phase, compromised accounts get more secure and new passwords. It also replaced the password with other access methods. Additionally, all vulnerabilities have been addressed, functionalities have been tested, and normal operations resumed.

6. Lessons Learned:

During any incident and response, mistakes are common. Learning from these highlights and experiences about what went wrong is a crucial step in enhancing your disaster recovery strategy. It entails gathering your complete team and delivering feedback on what worked and what didn’t, as well as making suggestions for how to improve the process.

These are the detailed information about each phase of the incident and the response plan.
