What is digital forensics?
Digital forensics is a structured process for identifying, preserving, analyzing, and documenting digital evidence following a security incident or cyberattack. The objective is to understand what happened, how the incident occurred, which systems or data were affected, and what activities an attacker performed.
Digital evidence can be found in sources such as logs, computers, servers, network traffic, cloud services, user accounts, and mobile devices. During a digital forensic investigation, these traces are analyzed to reconstruct the sequence of events and identify indicators of compromise. Evidence must also be preserved and documented in a way that maintains its integrity and allows the findings to be verified.
A useful analogy is the investigation of a physical crime scene. Investigators secure evidence before it disappears, analyze the available traces, and attempt to reconstruct what happened. In digital forensics, the evidence is instead found within digital systems and data.
Sicra and digital forensics
Digital forensics is important during serious security incidents because it gives organizations a stronger foundation for understanding the scope of an attack and determining the appropriate response. An investigation can help establish how an attacker gained access, which systems they moved through, and whether information was accessed, extracted, or manipulated.
Sicra supports organizations during security incidents with analysis, coordination, and response. Through monitoring and analysis of security data, Sicra can help identify suspicious activity, investigate the sequence of events, and provide organizations with a stronger basis for incident handling, recovery, and future security improvements.
