Detailed impact analysis, verification and compliance validation were done to identify and shorlist rules for optimization. .
After cross-verification with logs on the device, false positives were filtered out. Rules disablement and policy optimization exercise were carried out for every firewall. The filtered rules were then disabled and observed for over a month. Atier a month, the rules that did not have any impact were marked for deletion. The entire exercise resulted in higher performance and lower risks for the organization.
