What is Incident Response?

The process used by an organization to respond to and manage a cyberattack is known as incident response. A cyberattack or security breach may result in customer problems, threat to intellectual property, organizations' time and resources, and brand value. The incident response aims to mitigate damage and recover as soon as possible.

Incident response is when the Security Operation Center (SOC) takes full force to isolate and eliminate an attack before data is lost or the organization is permanently damaged.

Incident Response Plan

Responding to an event without a strategy results in avoidable harm, irritation, and resource wastage. A well-thought-out, tried-and-true incident response strategy allows the SOC to respond to, recover from, and manage the consequences of an incident. The incident response plan includes these steps:

1. Preparation: In this step, SOC Analysts analyze and define a security plan that guides the incident response plan and lab setup throughout the preparation stage.
2.  Identification: This step entails detecting and identifying threats and actual security occurrences.
3. Containment: After identification, one of the first actions is to restrict the damage and prevent additional penetration. And isolate the devices that are under attack.
4. Eradication: This step entails minimizing the risk and reverting internal root cause analysis to its initial state as closely as possible.
5. Recovery: The intrusion's cost and subsequent damage are calculated at this point. Also, recover to normal operations.
6. Lesson Learned: It is one of the most crucial and usually ignored stages. The incident response team and partners meet at this stage to discuss ways to improve future progress.

Incident Response Policy

The incident response policy aims to identify IT roles and responsibilities for cybersecurity incidents and data theft assessment and response. It includes

• Management responsibilities and processes assure prompt, effective, and orderly responses to security and privacy incidents.
• Security and privacy incidents are notified as soon as feasible through proper management procedures.
• Security and privacy incidents are evaluated to determine whether they should be classed as related to privacy incidents.
• Procedures for identifying, collecting, acquiring, and preserving information that can be used as evidence should be defined and followed.

Incident Response Procedure

While implementing incident response cybersecurity, the first goal is to plan correctly by creating a comprehensive incident response strategy. Here are the steps for incident response procedures.

• Assemble team
• Identify and determine the source
• Contain
• Eradication
• Recover
• Assess the size of the loss.
• Start the reporting procedure.
• Take steps to avoid a similar incidence in the future.
