Example text

In this section, we show the components of IPSec policies, and present a formal model for any general filtering policy. We then apply this model to the IPSec policy components. 1 IPSec Policy Components The protection offered by IPSec to certain traffic is based on requirements defined by security policy rules defined and maintained by the system administrator [6, 11]. , transport protocol, source address and port number, and destination address and port number. To define traffic protection rules, the IPSec standard specifies the policy operational guidelines that should be implemented by vendors rather than a specific policy model [12].

After removing the rule, we run the interfirewall anomaly analysis in order to highlight any potential anomalies that might be introduced in the modified policy. Modifying a rule in a firewall policy is also a critical operation. However, a modified rule can be easily verified and inserted based on the rule removal and insertion techniques described above. 7 Firewall Policy Advisor: Implementation and Evaluation We implemented the techniques and algorithms described in Sects. 3 in a software tool called the “Firewall Policy Advisor” or FPA.

Rule conflicts can occur due to IPSec misconfiguration within a single policy (called intra-policy conflicts) or due to the inconsistency between policies in different devices (called inter-policy conflicts). These conflicts may result in incorrect operation of IPSec and can lead to serious security threats including transmitting traffic insecurely, dropping legitimate traffic, and allowing undesired traffic into secure networks. Therefore, successful deployment of IPSec security is highly dependent on the availability of policy management techniques that can analyze, verify and purify IPSec policy rules with minimal human intervention.
