Which three tools are used for integrity verification of files? (Choose three.)
sha256sum: This tool calculates the SHA-256 hash of a file, which can be used for integrity verification by comparing the hash value with a known, trusted value.
md5sum: This tool calculates the MD5 hash of a file, which can also be used to verify its integrity by checking against a known hash value.
md5deep: This is a tool that provides recursive MD5 hash calculation, which can be useful for verifying the integrity of multiple files at once.
During an incident, the following actions have been taken:
- Executing the malware in a sandbox environment

Which two answer options are the BEST reasons to conduct post-incident reviews after an incident occurs in an organization? (Choose two.)
To help identify lessons learned and follow-up action: Post-incident reviews are critical for analyzing what went well and what could be improved, allowing the organization to apply lessons learned to future incidents.
