What is cybersecurity forensics?
Cybersecurity forensics
involves gathering, conserving, analyzing, and presenting electronic evidence to investigate and respond to cyber incidents, cybercrimes, and security breaches, sometimes referred to as digital forensics or cyber forensics. It requires using specialized techniques and tools to study digital artifacts, such as computer systems, networks, storage devices, and digital media, to find evidence related to cyberattacks, data breaches, and other cyber incidents. The main objectives of cybersecurity forensics are as follows:
1. Investigating Incidents: Cybersecurity forensics experts determine the origin, extent, and implications of a cyber incident or breach, including identifying the attack method, the affected systems, and the accessed or stolen data.
2. Attribution: They identify the individuals or organizations responsible for a cyberattack or other unauthorized activities. This involves analyzing malware, tracking digital traces, and examining attack patterns to attribute the incident to specific actors.
3. Collecting and Preserving Evidence: Experts gather digital evidence and preserve it in a manner that maintains its integrity and makes it admissible for legal or regulatory purposes. They ensure that the evidence is preserved throughout the investigation.
4. Analysis: They investigate the collected facts to reconstruct the chronology of the cyber incident, including its prelude, course, and aftermath. This involves examining artifacts such as log files, network traffic, memory dumps, and file timestamps to piece together the attack timeline and tactics.
5. Reporting and Documentation: They record the findings, analyses, and methodology of the investigation. They prepare comprehensive reports that convey the facts and conclusions in an understandable and systematic manner, which is crucial for legal proceedings and organizational decision-making.
6. Compliance with Laws and Regulations: Experts ensure that the investigation process complies with laws and regulations, including following the correct chain of custody protocols and adhering to the regulations governing the admissibility of evidence in court.
Cybersecurity forensics experts employ a variety of methods and equipment for their investigations, including:
- Using Data Recovery Tools to recover deleted or hidden files and information.
- Employing Network forensic tools to examine network traffic and detect irregularities.
- Utilizing Memory analysis tools to search for indications of malicious activity in volatile memory.
- Employing Malware analysis tools to examine and dissect dangerous malware.
- Using Forensic imaging tools to create precise replicas of storage devices (forensic images) for analysis.
By using cybersecurity forensics, organizations can gain a better understanding of cyber risks, recover from attacks, and take measures to prevent similar incidents in the future. It also aids in identifying and prosecuting perpetrators, ensuring the overall security of digital systems and data, and playing a crucial role in both cybersecurity and law enforcement.
