What is Incident Response Plan (IRP) in Cybersecurity?

In an era dominated by technological advancements, the significance of cybersecurity cannot be overstated. Incident response (sometimes called cybersecurity incident response) refers to an organization’s processes and technologies for detecting and responding to cyberthreats, security breaches or cyberattacks. As our lives become increasingly intertwined with digital platforms, the need to protect sensitive information and digital assets has never been more critical.

Cybersecurity serves as the frontline defense against a myriad of threats, ranging from malicious attacks to data breaches. Within this realm, one key aspect takes center stage – “Cybersecurity Incident Response Strategies.”

The term suggests a proactive strategy in handling cybersecurity incidents, emphasizing the need for both prevention and effective response. In this guide, we’ll delve into cybersecurity incident response strategies, revealing methodologies for organizations and individuals to secure their digital landscape.

  • Event — a change in system settings, status, or communication. Examples include server requests, permissions update, or the deletion of data.
  • Alert — a notification triggered by an event. Alerts can warn of suspicious events or of normal events that need your attention. For example,the use of an unused port vs storage resources running low.
  • Incident — an event that puts your system at risk. For example, theft of credentials or installation of malware.

Understanding Cybersecurity Incidents

In our exploration of cybersecurity incident response strategies, it’s paramount to begin by comprehending the very essence of cybersecurity incidents.

A cybersecurity incident is any malicious activity or security breach threatening digital information’s confidentiality, integrity, or availability. These incidents span various cyber threats, including malware attacks, phishing schemes, and sophisticated forms of intrusion.

Understanding the potential impact of cybersecurity incidents is crucial. The ramifications extend beyond just technological disruptions; they can lead to financial losses, reputational damage, and compromise the trust of stakeholders. The ripple effect of inadequate incident response can be far-reaching, underscoring the need for a proactive and strategic approach.

The Anatomy of Cybersecurity Incident Response

Now that we’ve established a foundational understanding of cybersecurity incidents, let’s delve into the intricate framework of an effective cybersecurity incident response plan.

A successful incident response plan is multifaceted, involving a well-coordinated set of actions. From the initial stages of preparation and identification to the critical steps of containment, eradication, and recovery, each component plays a crucial role in mitigating the impact of a cybersecurity incident. The process doesn’t end there; continuous improvement is facilitated through a thorough analysis of lessons learned.

The acronym PICERL encapsulates the key stages of incident response: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. This structured approach ensures a systematic and comprehensive response to incidents, minimizing damage and facilitating a swift return to normalcy. As we unravel the layers of PICERL, we uncover the strategic elements that form the backbone of an effective cybersecurity incident response plan.

A Comprehensive Overview of the Incident Response Lifecycle

This article explores the six phases of the incident response lifecycle, as outlined by SANS. In contrast to the four-step NIST incident response process, SANS provides a more detailed framework.

These six steps occur in a cycle each time an incident occurs. The steps are:

  1. Preparation
  2. Identification of Threats
  3. Containment of Threats
  4. Elimination of Threats
  5. Recovery and Restoration
  6. Feedback and Refinement


During the initial preparation phase, existing security measures and policies are scrutinized for effectiveness. A risk assessment is conducted to identify vulnerabilities and prioritize asset protection. This phase involves refining or creating policies and procedures, including a communication plan and role assignments for incident response.

Identification of Threats

Teams employ tools and procedures established in the preparation phase to detect and identify suspicious activities. When an incident is confirmed, the focus shifts to determining the nature, source, and goals of the attack. Communication plans are activated to inform relevant parties, and all evidence collected is safeguarded for future analysis and potential legal proceedings.

Containment of Threats

Upon identification of an incident, containment methods are swiftly enacted to minimize damage. Short-term containment isolates immediate threats, while long-term containment applies additional access controls to unaffected systems. Clean, patched versions of systems are prepared for the recovery phase.

Elimination of Threats

After containment, teams work to eliminate attackers and malware from affected systems. This process continues until all traces of the attack are eradicated. In some cases, this may involve taking systems offline to replace compromised assets with clean versions.

Recovery and Restoration

Teams bring updated replacement systems online in the recovery phase. Ideally, systems are restored without data loss, but if necessary, teams determine the last clean data copy and restore from it. The recovery phase extends as systems are monitored to ensure attackers do not return.

Feedback and Refinement

The lessons learned phase involves a thorough review of the response. Teams evaluate what went well, what didn’t, and propose improvements for the future. Incomplete documentation is finalized during this phase, ensuring a continuous cycle of improvement in incident response strategies.

What Does an Incident Response Team Do?

An incident response team, also known as a computer security incident response team (CSIRT), cyber incident response team (CIRT), or computer emergency response team (CERT), is tasked with executing your Incident Response Plan (IRP).

The primary responsibilities of your CSIRT encompass the prevention, management, and response to security incidents. This entails thorough research into emerging threats, the formulation of effective policies and procedures, and the education of end-users in cybersecurity best practices.
