OWASP TOP TEN:#2 CRYPTOGRAPHIC FAILURE

 WHAT IS CRYPTOGRAPHIC FAILURE?

Cryptographic failures are where attackers often target sensitive data, such as passwords, credit card numbers, and personal information, when you do not properly protect them. This is the root cause of sensitive data exposure. Cryptographic failures are vulnerabilities in cryptographic systems that can expose sensitive data. 

Cryptographic errors are mistakes or weaknesses in the design, implementation, or usage of cryptographic algorithms, protocols, or systems. They can compromise the security, privacy, or integrity of data and communications, and expose them to attacks such as eavesdropping, tampering, or forgery.

TYPES OF CRYPTOGRAPHIC FAILURE:

Weak encryption: Using weak encryption algorithms or outdated cryptographic libraries 

Poor key management: Using hard-coded passwords, or having poor practices for managing cryptographic keys 

Insecure hashing: Using insecure hashing algorithms or deprecated hash functions 

Insufficient randomness: Not using enough randomness (entropy) for cryptographic functions 

Transmitting secret data in plain text: Sending secret data without encryption 

Using old algorithms: Using old or less-secure algorithms 

Insecure certificate validation: Having insecure implementations of certificate validation

HOW TO PREVENT CRYPTOGRAPHIC FAILURE:

Use secure configurations for operating systems, frameworks, libraries, and applications

Keep software updated and patched

Use strong random number generation

Avoid using outdated cryptographic libraries
