How would you handle overlapping ACL rules, or multiple entries that contradict one another within the same ACL?
To handle overlapping ACL rules or contradicting entries within the same ACL, follow these steps :
1. Identify conflicting rules by analyzing the ACL and noting any overlaps or contradictions.
2. Determine the desired outcome for each conflict, considering security requirements and business needs.
3. Prioritize rules based on their importance to achieve the desired outcomes.
4. Reorder or modify rules as needed to resolve conflicts while maintaining priority. Use explicit deny statements if necessary to block undesired access.
5. Test the modified ACL in a controlled environment to ensure it functions as intended without causing unintended consequences.
6. Document changes made to the ACL, including reasons for modifications and expected results.
7. Implement the updated ACL in the production environment and monitor its performance to confirm that conflicts have been resolved.
