 During the collection phase of the forensic process, data related to a specific event is labeled and recorded to preserve its integrity. This step ensures that the data remains unaltered and authentic from the time of collection until it is presented as evidence,maintaining the chain of custody. References := Cisco Cybersecurity Operations Fundamentals - Module 6: Security Incident Investigations

In digital forensics, hash values are used to verify the integrity of disk images. When a disk image is created, cryptographic hash functions such as MD5 or SHA-256 are calculated and recorded. These hashes act as a digital fingerprint of the data at the time of acquisition.

An untampered disk image maintains the same hash value throughout the investigation, proving that the data has not been altered. A tampered disk image, however, will produce a different hash value because even the smallest modification to the data changes the resulting hash. This difference immediately indicates that the integrity of the evidence has been compromised.

Options A, C, and D are incorrect because encryption, access permissions, and compression do not define whether an image is tampered. Cybersecurity and forensic documentation consistently emphasizes hash verification as the primary method for validating forensic integrity.

Therefore, the key difference is that a tampered image has a different hash value, making Option B correct.

A buffer overflow attack occurs when more data is written to a buffer than it is designed to hold. This excess data can overwrite adjacent memory locations, leading to the execution of malicious code or crashing the system. Buffer overflows are a common vulnerability that attackers exploit to gain unauthorized access to systems.

In a Security Operations Center (SOC) environment, a vulnerability management metric is a quantifiable measure used to assess the effectiveness of the vulnerability management program. A full assets scan is a metric that can be used to determine the coverage and frequency of vulnerability scans across all assets. This helps in identifying unscanned assets and ensuring that all parts of the network are regularly checked for vulnerabilities1.
