Section 8.79 Obfuscation Flashcards
Objectives 1.4 Explain the importance of using appropriate cryptographic solutions. Objectives 2.3 Explain various types of vulnerabilities. Objectives 2.4 Given a scenario, you must be able to analyse indicators of malicious activity.
Obfuscation Techniques in Data Security
Steganography
● Conceals a message within another to hide its very existence
● Involves altering image or data elements to embed hidden information
● Primary goal is to prevent the suspicion that there’s any hidden data at all
● Used alongside encryption for added security
● Detection is challenging due to hiding data in plain sight
Obfuscation Techniques in Data Security
Tokenization
● Substitutes sensitive data with non-sensitive tokens
● Original data securely stored elsewhere
● Tokens have no intrinsic value
● Reduces exposure of sensitive data during transactions
● Commonly used for payment systems to comply with security standards
Obfuscation Techniques in Data Security
Data Masking (Data Obfuscation)
● Disguises original data to protect sensitive information
● Maintains data authenticity and usability
● Used in testing environments, especially for software development
● Reduces the risk of data breaches in non-production settings
● Common in industries handling personal data
● Masks portions of sensitive data for privacy, e.g., credit card digits, social
security numbers
