Guide to Building an Efficient Incident Response Team

With the growing number of threats and an increase in their frequency, it is becoming critical for organizations to maintain an incident response team. A dedicated group of professionals who can defend servers, networks and other IT infrastructure and can respond actively to the security incidents is the need of the hour. The team may comprise of experts working either full-time, part-time or on consulting services.

The comprehensive response provided by an incident response team includes changes recommended to systems or organizational practices as protective guidance against future incidents. It also points at non-technical concerns, such as status reporting, handling personnel issues, assisting counsel, managing internal communications, etc.

The Role of an Incident Response Team:

Incident response is a group of members who handle independent roles, multiple roles, or shared roles based on the core requirement. Here we list out a few general roles of an incident response team, but there may be more specific roles based on one’s IR plan. Before we define the team roles, here are a few points that should be considered while defining them:

Define, Document, and Communicate – The roles should be documented and clearly communicated to them to ensure clarity and coordination within the team. Well-defined and documented team roles enable efficacy of the team in case of crisis.

Establish, Confirm, and Publish Channels of Communication – Effective communication binds the team and keeps them motivated. This is significant in incident handling as communication plays a major role when dealing with threats. Listing out all contacts (internal and external) and defining and documenting a planned strategy about whom to contact and the flow of tasks or communication such as media, law enforcement, etc. minimizes panic and reduces the time spent on containment too.

Inter-departmental Participation Required – Incident response team seeks support from the IT security department as well as from legal and HR. IR being part of the IT security seeks the participation of at least one executive from major business units. The HR and legal departments support filling the requirement gaps, corporate security, privacy and consulting services.

 

Role Responsibility
Team Leader Coordinates and leads incident response team activity by encouraging the team to minimize damage and maintain a quick containment time.
Lead Investigator Analyses evidence, directs the team members, determines root cause, and implements a rapid system.
Communications Lead Acts as an active communication link for the management, inter-departments, stakeholders, legal advisors, and others concerned with the IR process.
Documentation Lead Documents investigation process, team activities, and discovery and recovery tasks. Also, determines a timeline for every stage of the incident.
HR/ Legal Representation IR team should have an external supporting executive for legal and HR guidance so that the response is performed efficiently.

The main responsibility of an incident response team is to deal with the impact of an attack and the containment process.  Hence, they play an important role in drafting the overall security policy in the organization. The more information incident response team brings to the management, the better the company can strengthen the security system and establish channeled communication during a crisis.

An incident response team investigates the significance of the threat, reports the incident impact, and responds and communicates across the company. When not working on any threats, incident response team meets regularly to review security trends and response procedures within the organization. If required, they draft new strategies and implement them after being approved by management.

Choosing Incident Response Team Members

Incident response is a 24/7 job which demands the attention of 365 days of a year. Though practically, one cannot be onsite forever but consider staying closer to the workplace so that commuting shall become easy. While fulltime hiring may not be possible, your existing information security team can be trained to acquire the necessary skills to respond quickly when required.
