What is an Incident Response Team?

An incident response team is responsible for carrying out your Incident Response Plan (IRP). This group is called a Computer Security Incident Response Team (CSIRT). Your CSIRT’s primary responsibilities are to prevent, manage, and react to security incidents, including investigating risks, implementing rules and procedures, and teaching end users the best cybersecurity practices.

Building a CSIRT in Your Organization

The quality of your CSIRT heavily influences the effectiveness of your incident response efforts. If you cannot fulfill all the required roles and duties, your reaction will have gaps, which might result in higher damage and lengthy assaults. Here is a list of the talent you will need to build a productive CSIRT.

  • Team Leader: Their primary role is communicating incidents to the executive board and ensuring the team gets appropriate attention and a budget.
  • Incident Manager: Holds the CSIRT members accountable and summarizes incident reports before escalating issues to the higher management.
  • Lead Investigator: They include a security analyst or specialized incident responder responsible for investigating the incidents.
  • Legal: The legal team advises the company on the need to report security incidents and handle any ramifications from the occurrence, such as shareholder or employee litigation.

Incident Response Team Models

The incident response team models include;

  • Central: It’s a centralized body in charge of the company’s incident response.
  • Distributed: It entails various incident response teams with each group accountable for a physical location like a department, branch office, or part of the IT infrastructure.
  • Coordinated: It is a central incident response team that collaborates with distributed incident response teams without commanding them or having any authority. The core team acts as a knowledge hub, providing help with complicated, critical, or organizational-wide crises.

Selecting a Team Model

There are several considerations for selecting a team model, and they include:

Should Staff Be Full-Time or Part-Time?

Part-time workers may form a virtual incident response team, similar to a volunteer emergency response unit. The IT help desk might be the first point of contact in the event of an issue. They may do an initial investigation, quickly summon incident response team members, and react to the case with whoever is available.

What Availability Do You Need?

You need to decide if you want 24/7 response availability and what degree of availability you want. For example, is it sufficient for teams to react remotely, or do they need to be present on-site? Your Staff should ideally be accessible in real-time and in person.

Should Staff Be Security Experts?

The more expertise your team has, the more effective it may be. Many companies, however, lack a high degree of security competence in-house. In this instance, you may wish to have external specialists on hand to support your in-house team during reaction efforts.

What Is Your Budget?

Your IR budget has a significant impact on limiting the above factors. When assembling your team, you must be realistic about the required budget and how money should be distributed.

What Are Incident Response Services?

These are managed services that may be used instead of or in addition to in-house CSIRT. Incident Response Services are often provided on a retainer basis, with a monthly fee and limited services. The advantage of these services is that they often give better knowledge than is available in-house and may provide monitoring and reaction 24/7. This service is often accompanied by a Service Level Agreement (SLA) that ensures confidentiality and responsiveness.

Incident Response Automation

Effective incident response is time-sensitive and requires teams to detect threats and initiate IRPs as soon as possible. Unfortunately, most teams cannot analyze all notifications in real-time to assess whether anything is an incident, which might result in occurrences going unnoticed or being discovered after considerable harm. Automating parts of the security incident response can help you avoid these delays by quickly triaging results and identifying incidents.
