What are the six phases of a cybersecurity incident response plan?

The incident response plan’s six phases teach how to handle a data breach. It’s a documented plan with six steps assisting IT professionals and staff in recognizing and responding to cybersecurity issues like data breaches or cyber assaults. Regular updates and training are necessary to create and manage an incident response strategy effectively.

A Cyber Incident Response Plan is a simple document instructing IT and cybersecurity experts on what to do in security incidents like data breaches or leaks. Any serious organization about cybersecurity needs a comprehensive cyber incident response strategy. Based on research, experience, and training, this plan should be regularly revised.

But how do you put one together, and what are the six steps of an incident response plan experts refer to? This blog aims to address these critical issues to help you develop an effective reaction strategy to cyber assaults and security concerns.

A cyber incident response strategy should assume that cybercriminals may target your company in the future.

What is the best way to build a cybersecurity incident response plan?

Establishing a phased incident response plan is crucial for addressing a suspected data breach. It involves evaluating certain areas of need within each phase.

  • Preparation
  • Identification¬†
  • Containment
  • Eradication
  • Recovery
  • Learned Lessons

Let’s closely examine each phase and identify the issues that require addressing.

1. Planning:

This phase of the cybersecurity incident response plan focuses on preparing for a cybersecurity issue. You must connect the organization’s rules on personal information and sensitive data protection, as well as network security goals, with the organization’s technology architecture in this phase.

During this phase, you must guarantee that all employees have a basic understanding of cybersecurity as well as basic training in dealing with a cyber crisis. In the event of an emergency, everyone must be aware of their roles and responsibilities.

2. Recognization

Here’s the procedure for determining whether or not you’ve been hacked. A breach, also known as an incident, can occur in a variety of ways.

Concerns to address include:

  • When did the incident take place?
  • How was it discovered?
  • Who first noticed it?
  • Have any other areas been affected?
  • What is the scope of the compromise?
  • Does it affect operations?
  • Has the event’s source (point of entry) been identified?

3. During this phase, you must take whatever actions possible to minimize damage after experiencing an attack:

In this step of the incident response strategy, you must analyze actions to contain the breach’s effects. Consider which systems to turn off, determine the safety of erasing anything, and decide if it’s necessary. Develop a short-term plan and establish a long-term strategy for addressing the attack’s consequences. In phase three of the cyber event response strategy, you must address all of these questions.

4. Complete Eradication:

After containing the problem, you’ll need to identify and eliminate the root cause of the breach. This entails safely removing all malware, hardening systems, patching vulnerabilities, and installing updates.

Whether you handle it yourself or hire someone, thoroughness is crucial. Any traces of malware or security flaws left behind can result in data loss and increased liabilities.

This phase involves ensuring that your systems are entirely free of harmful information. However, be cautious not to lose any critical data in the process.

In today’s world, everyone is susceptible to attacks. Nonetheless, allowing malicious software or security issues to persist in your system can lead to severe damage to your public image and increased legal liability.

5. Recuperation:

This is the procedure for repairing and reinstalling damaged systems and devices in your company’s environment. It’s critical to get your systems and business activities back up and running without risk of another breach during this time.

Concerns to be addressed

  • When will the systems be ready to go back into production?
  • Have you patched, hardened, and tested your systems?
  • Is it possible to restore the system from a reliable backup?
  • How long will you monitor the affected systems, and what will you check for throughout that time?
  • What technologies will be used to ensure that similar attacks do not occur again? (Intrusion detection/protection, file integrity monitoring, etc.)

6. Lessons Learned:

We’ll assert that this represents one of the most crucial stages of the incident response strategy. Yes, anyone can be hacked and will be. However, it’s how we respond to the breach and what we learn from it that makes the difference.

During this phase, it’s imperative to convene all members of the Cybersecurity Incident Response team and discuss what transpired. This process is akin to taking a retrospective look at the attack. This step should be completed within two weeks of the incident. In this phase, you’ll revisit the documentation prepared in phase two. Consequently, you can assess what occurred, why it occurred, and what steps were taken to contain the situation.

Most significantly, the company must deliberate on whether anything could have been done differently during this period. Were there any flaws in the incident response strategy? Was there a department or stakeholder who could have acted more quickly or differently? The primary objective of this phase is to glean insights from the attack to prevent its recurrence. If it does occur again, the aim is to handle the issue even more effectively.
