As cyber threats continue to grow in number and sophistication, organizations are investing heavily in incident response teams (IRTs) to detect, investigate, contain, eradicate, and recover from computer incidents. But what exactly do IRTs do, and how do they specialize? In this article, we’ll explore the roles and responsibilities of IRTs and other types of cybersecurity teams, as well as real-life examples of organizations that have successfully navigated major security incidents with the help of these specialized teams.
What is an Incident Response Team?
An incident response team (IRT) is a group of cybersecurity professionals who are responsible for identifying and responding to computer incidents. The primary goal of an IRT is to minimize the impact of an incident on an organization’s systems, data, and operations, while also ensuring compliance with relevant regulations and standards.
IRTs typically consist of several specialists with different skill sets, including:
-
Incident response analysts: responsible for collecting and analyzing data related to the incident, as well as identifying patterns and trends that could indicate future attacks.
-
Forensic investigators: responsible for collecting and analyzing digital evidence related to the incident, as well as reconstructing events leading up to the incident.
-
Malware analysts: responsible for identifying and analyzing malicious software or other types of malware that may have contributed to the incident.
-
Network engineers: responsible for managing an organization’s networks and systems, including identifying vulnerabilities and implementing security measures to prevent future attacks.
-
Communication specialists: responsible for communicating with stakeholders, including employees, customers, regulators, and law enforcement agencies, about the incident and the steps being taken to respond.
How do IRTs Specialize?
While all IRTs share certain common responsibilities, there are also many specialized roles within an IRT. Some of the most common specializations include:
-
Incident response analysts: as mentioned earlier, incident response analysts are responsible for collecting and analyzing data related to the incident. They may specialize in specific types of data analysis, such as network traffic analysis or endpoint analysis.
-
Forensic investigators: forensic investigators specialize in collecting and analyzing digital evidence related to the incident. They may specialize in specific types of forensics, such as disk imaging or memory analysis.
-
Malware analysts: malware analysts are responsible for identifying and analyzing malicious software or other types of malware that may have contributed to the incident. They may specialize in specific types of malware, such as viruses or worms.
-
Network engineers: network engineers specialize in managing an organization’s networks and systems, including identifying vulnerabilities and implementing security measures to prevent future attacks. They may specialize in specific areas of networking, such as firewall configuration or intrusion detection systems.
-
Communication specialists: communication specialists are responsible for communicating with stakeholders about the incident and the steps being taken to respond. They may specialize in specific types of communication, such as media relations or public affairs.
Real-Life Examples: Who Specializes Solely in Incident Response?
To further illustrate who specializes solely in incident response, let’s take a closer look at some real-life examples:
-
Target Data Breach: In the aftermath of the 2013 Target data breach, the retail giant created an IRT that was responsible for detecting, investigating, containing, eradicating, and recovering from the incident. The team worked closely with law enforcement agencies and forensic experts to understand the root cause of the incident and implement measures to prevent future breaches. While there may have been some overlap between the roles of incident response analysts, forensic investigators, and malware analysts, each specialist had a specific area of focus that contributed to the team’s overall success in responding to the incident.
-
Equifax Data Breach: In response to the 2017 Equifax data breach, the credit reporting agency created an IRT that was responsible for detecting, investigating, containing, eradicating, and recovering from the incident. The team worked closely with law enforcement agencies and forensic experts to understand the root cause of the incident and implement measures to prevent future breaches. Again, there may have been some overlap between the roles of incident response analysts, forensic investigators, and malware analysts, but each specialist had a specific area of focus that contributed to the team’s overall success in responding to the incident.
-
WannaCry Ransomware Attack: In May 2017, a global ransomware attack known as WannaCry affected organizations around the world, including several major hospitals and government agencies. To respond to the incident, many organizations created IRTs that were responsible for detecting, investigating, containing, eradicating, and recovering from the attack. While there may have been some overlap between the roles of incident response analysts, forensic investigators, and malware analysts, each specialist had a specific area of focus that contributed to the team’s overall success in responding to the incident.
Conclusion
Incident response teams (IRTs) are critical components of any organization’s cybersecurity strategy, responsible for detecting, investigating, containing, eradicating, and recovering from computer incidents. While there may be some overlap between the roles of incident response analysts, forensic investigators, malware analysts, network engineers, and communication specialists, each specialist has a specific area of focus that contributes to the team’s overall success in responding to incidents. By investing in IRTs and other specialized cybersecurity teams, organizations can better protect their systems, data, and operations from the growing threat of cyber attacks.
