What does obfuscation refer to in the context of cybersecurity?
Intentionally making data unclear or difficult to understand
Which obfuscation technique involves hiding information within images, audio files, or other multimedia?
Steganography
What is the process of replacing Personally Identifiable Information (PII) data with a random value using a table called?
Tokenization
What is a key requirement for tokenization to add another layer of security to the data?
Keeping the table used for tokenization secret/secure
Which obfuscation technique involves replacing, encrypting, or scrambling sensitive information while maintaining usability for testing or analytics purposes?
Data masking
What does data masking involve?
Substituting real data with fictional or partially anonymized data
What is the primary purpose of obfuscation techniques in enhancing data security and privacy?
To protect sensitive information from unauthorized access
