What is difference between Digital Forensic and Reverse Engineering?

Question

I am not able to understand exact difference in Digital Forensic and Reverse Engineering. Will Digital Forensic has anything to do with decompilation, assembly code reading or debugging?

Thanks

Answer 1

Digital Forensic practice usually involves:

• looking at logfiles
• doing recovery of unlinked filesystem objects (e.g deleted files)
• recovering browsing history through cache, etc.
• looking at timestamps of files

(usually for the purpose of law enforcement)

Reverse Engineering usually involves determining how something works by:

• looking at binary file formats of multiple files (or executables) to determine patterns
• decompilation of binary executables to determine intent of the code
• black-boxing and/or debugging of known-good applications to determine nominal behaviour with respect to data.

(usually for the purpose of interoperability)

They're completely different activities.

EDIT: so many typos.
