OWASP Periodic Table of Vulnerabilities - Insufficient Data Protection
Insufficient Data Protection
Root Cause Summary
Sensitive data is not sufficiently protected against disclosure, modification or non-repudiation.
Browser / Standards Solution
Generic Framework Solution
Provide a configuration-based suite of encryption utilities for all data security needs. This includes safeguards to prevent tampering (with Hash-based Message Authentication Code or HMAC) and eavesdropping (with symmetric or public key encryption).
The framework solution must be designed for ease of key rotation and transparent, simple substitution of more secure algorithms as cryptographic techniques improve.
Custom Framework Solution
Custom Code Solution
Identify which kinds of data need to be protected (e.g. Personally Identifiable Information (PII) or authentication and identification data). Examples of PII are names, passport numbers, address information and personal characteristics.
Never store more information than is needed. Minimize the use, collection and retention of data.
Use a risk-based approach, order the data by impact level (for example low, moderate and high) if it is to be inappropriately accessed, used or disclosed.
Make sure that all applicable (eg. local, federal) laws are obeyed.
Discussion / Controversy
Data protection laws vary from country to country. Ensure that the correct mitigations and protections have been taken.
