Cyberattacks can affect any organization's system or network. The process used by an organization to respond to and manage a cyberattack is known as incident response. It helps you keep track of security incidents, analyze and contain risks, and remove them from your network.
Incident Response
Plan (IRP)
An Incident Response Plan (IRP) is a structured series of stages that must be followed to ensure that every part of a cyber incident is investigated and documented. The tricky part is to determine which business components are most beneficial to produce the most productive IRP. You have a good chance of defending against these types of attacks and designing an IRP to best suit the firm's environment if you can identify where a company is most likely to be targeted.

Incident Response Steps
The following are the defined steps that should be included in every cybersecurity IRP:
- Preparation: Preparation is the first and essential step in responding to cybersecurity incidents. You will require a solid plan in place to help your incident response team, as, without it, even the strongest team will be unable to resolve a cyber incident successfully. Teams must establish policies, procedures, and agreements for incident response management, create standards for smooth communication, access their threat detection capabilities, and more to adequately address security incidents.
- Identification: It is critical to have a proper setup to recognize when an incident has occurred. This is usually where intrusion detection system alerts appear. Web filtering gateways detect suspicious external connections. SIEM solutions connect the dots between an attacker passing through the internal network and an endpoint solution detecting the opening of a phishing email. In any case, qualified security personnel must act quickly to escalate and respond to the alerts.
- Containment: After an incident has been identified, the threats must be contained. This phase aims to contain the damage and use containment strategies to prevent it from getting worse. It is one of the crucial steps of incident response.
- Eradication: Eradication is one of the most challenging stages of the incident response process because it requires forensic analysis to identify the extent of the threat actor's presence. Security professionals must ensure that whatever they do in the eradication step removes the threat actor's presence and access to the system. This entails reimaging systems, looking for backdoors, and, most importantly, pinpointing the incident's core cause.
- Recovery: After eradication, the recovery stage begins. It is critical at this step to get the infected systems back up and running to minimize any potential financial losses related to the infected system's downtime. Simply, it refers to the testing of fixes in the eradication phase as well as the transition to normal operations.
- Lessons learned: Lessons learned is also one of the essential stages since it demonstrates to everyone how the incident occurred and how efficiently the exploit's attack vector was closed. The main lessons from this phase are to improve your incident response capability and your security footprint.
