Is deobfuscation illegal?

Deobfuscation itself isn't illegal, but it depends on how it's used. Security researchers often deobfuscate code to study malware or check for vulnerabilities, which is legal.

What are three tools that can be used in the data obfuscation process?

Data masking, encryption, and tokenization are three common data obfuscation techniques. Each type has strengths in protecting against destructive malware.
