Security Incident Management and Forensics /Digital Forensics and Incident Response (DFIR)

Security Incidents in Digital Forensics and Incident Response (DFIR) is a field within cybersecurity that focuses on the identification, investigation, and remediation of cyberattacks.

DFIR has two main components:

  • Digital Forensics: A subset of forensic science that examines system data, user activity, and other pieces of digital evidence to determine if an attack is in progress and who may be behind the activity.
  • Incident Response: The overarching process that an organization will follow in order to prepare for, detect, contain, and recover from a data breach.

Due to the proliferation of endpoints and an escalation of cybersecurity attacks in general, DFIR has become a central capability within the organization’s security strategy and threat hunting capabilities. The shift to the cloud, as well as the acceleration of remote-based work, has further heightened the need for organizations to ensure protection from a wide variety of threats across all devices that are connected to the network.

Though DFIR is traditionally a reactive security function, sophisticated tooling and advanced technology, such as artificial intelligence (AI) and machine learning (ML), have enabled some organizations to leverage DFIR activity to influence and inform preventative measures. In such cases, DFIR can also be considered a component within the proactive security strategy.

Security Incident Management and Forensics

How is Digital Forensics Used in the Security Incident sResponse Plan

Security Incidents in Digital forensics provides the necessary information and evidence that the computer emergency response team (CERT) or computer security incident response team (CSIRT) needs to respond to a security incident.

Digital forensics may include:

  • File System Forensics: Analyzing file systems within the endpoint for signs of compromise.
  • Memory Forensics: Analyzing memory for attack indicators that may not appear within the file system.
  • Network Forensics: Reviewing network activity, including emailing, messaging and web browsing, to identify an attack, understand the cybercriminal’s attack techniques and gauge the scope of the incident.
  • Log Analysis: Reviewing and interpreting activity records or logs to identify suspicious activity or anomalous events.

In addition to helping the team respond to attacks, digital forensics also plays an important role in the full remediation process. Digital Forensics may also include providing evidence to support litigation or documentation to show auditors.

Further, analysis from the digital forensics team can help shape and strengthen preventative security measures. This can enable the organization to reduce overall risk, as well as speed future response times.
