A cyber incident response plan (IRP) is essential to have to protect your PII data. Having a strategic plan in place is very helpful to address the cybersecurity issues and to protect the financial and reputational consequences caused by a privacy incident breach.

The basic purpose of security incident response is to validate that businesses are well informed about crucial security incidents and respond instantly to stop the invader. This helps in minimizing the damages and preventing consecutive attacks or similar incidents in the future.

But what privacy incidents are and what are the phases involved in the incident response process are the key concerns that experts seem to be talking about? In this blog, we will find the answer to these important questions to help you create an effective incident response plan;

What are the Privacy Incidents?

Privacy incidents are the security breaches that involve the disclosure of and access to any of your PII/PHI where people other than authorized users have potential access to your data or its use for an unauthorized purpose.

However, it is important to distinguish between privacy incidents and other types of incidents. If you or any of your partner suspect that a security breach qualifies for a privacy incident, your incident response team should involve your legal team instantly.

Phases of Building a Strong Incident Response Plan

Although every business demands a different plan for cyber security incident response, all IRP’s follow the same necessary components as they go through the six-step process. Make sure to address all these phases involved in the IRP, before a data breach occurs.

Phase 1 – Get Prepared:

the very first step involves the preparation that enables an incident response (IR) team to respond to a potential security breach or incident. In this phase, you need to establish the policies and procedures involved in the incident response management and to establish effective internal/external communication, and documentation for both before and after the incident.

Another aspect of this phase is to prevent incidents by maintaining the security of your networks, systems, and applications. A strong cyber incident response plan must have the ability to keep the number of incidents considerably low.

Phase 2 – Detect:

This phase is to determine whether business data has been breached or not. It includes the declaration and primary classification of the incident. The detection phase is dependent on the security and monitoring tools, insider information, or openly available threat information. Detection is made by identifying suspicious activities, unfamiliar login attempts, unexpected new files, unexpected user accounts or user logins, and more.

Phase 3 – Containment:

Once you have gathered all the necessary information about the incident, it’s time that your IR team needs to focuses on the containment of the threat for avoiding any further damage. This phase requires planning for strategies to contain the breach and to prevent any loss of your personal data. This could include detaching the impacted device from the network or back-up your systems for restoring normal business operations.

Phase 4 – Neutralization:

The fourth phase requires your IR team to work towards a permanent solution with the addition of a process liable for repairing all the affected units. This is a process to eliminate the threat out of your infected system or network. Furthermore, they discover the root cause of the incident and ultimately recognize how it was affected to avoid similar attacks.

Phase 5 – Recovery:

This phase will focus on analyzing the incident for its technical and policy implications. From the recovery of your data to anything left in the restoration process, this phase covers it all. This phase will determine the time taken to return systems to normal, checking of systems for patching and testing, to check whether a system can be securely restored with a backup and how much time systems require to be monitored.

Phase 6 – Review:

The final step in the IRP is to revisit the entire process. It is important to document all the information throughout the process to avoid any kind of breach in the future. Learning from your mistakes and paying attention to what went wrong is very crucial for improving your ongoing incident recovery plans.

A strong incident response plan needs to include comprehensive information about every single stage of an incident. It becomes hard for companies to plan and execute the process on their own. The best way is to take the help of a reliable cyber security software solutions company to help you in the entire process.
