Join Marc Menninger for an in-depth discussion in this video File integrity checking tool demo, part of Performing a Technical Security Audit and Assessment.
- [Instructor] To illustrate how…file integrity checking works, I'll the Hash Tool,…which is a simple, free file hashing utility…from Digital Volcano.…I'll open the Hash Tool and select a file I'd like the tool…to generate a hash for.…This is the hash of the file's contents.…We'll use this as our baseline hash.…Now I'll go into the file and make a small change.…I'll just delete this comma and save the file.…
Now I'll run a validation hash of the file…and see what happens.…We can see that these hashes are completely different…even though I only made a small change.…Now I'll go back into the file and replace the comma.…Then I'll rerun the hash.…Here you can see that by replacing the comma,…the hash is once again the same as the baseline…and I've restored the integrity of the file.…
While you may not use hash tools in exactly this way…to conduct security assessments,…this demo showed you the principle…behind file integrity checking.…
