Top 5 Risks of "Dirty" Firewalls

Firewall rules are notoriously complex and voluminous in nature. Ironically, the more secure you try to be, the more complexity you create. Firewall proliferation not only driven by the number of physical sites, but also how fine-grained you attempt to make your network security. Along with more firewalls, you also end up with more rules, sometimes tens of thousands of them. On its own, this type of complexity is not a security issue. However, there is a strong correlation between the complexity of the firewall and the number of mistakes in the policy. Each mistake in turn adds unnecessary complexity. Over the years, these problems compound upon one another, resulting in an unmanageable policy, deteriorated firewall performance, increased risk and increased management costs. In this webinar, we discuss the top 5 risks the team at FireMon, the leading network security policy software vendor, finds when assessing complex firewall infrastructures as well as the types of analysis you can perform to clean up your firewalls effectively and safely and prevent rules from getting out of hand and outdated in the future.
