  3. Analysis of Firewall Policy Rules Using Data Mining Techniques: Network Operations and Management Symposium, 2006. NOMS 2006. 10th IEEE/IFIP (2006), pp. 305-315.Firewa ll is the de facto core technology of today's network security and defense. However, the management of firewall rules has been proven to be complex, error-prone, costly and inefficient for many large-networke d organizations. These firewall rules are mostly custom-designe d and hand-written thus in constant need for tuning and validation, due to the dynamic nature of the traffic characteristic s, ever-changing network environment and its market demands. One of the main problems that we address in this paper is that how much the firewall rules are useful, up-to-dated, well-organized or efficient to reflect the current characteristic s of network traffics. In this paper, we present a set of techniques and algorithms to analysis and manage firewall policy rules: (1) data mining technique to deduce efficient firewall policy rules by mining its network traffic log based on its frequency, (2) filtering-rule generalization (FRG) to reduce the number of policy rules by generalization , and (3) a technique to identify any decaying rule and a set of few dominant rules, to generate a new set of efficient firewall policy rules. The anomaly detection based on the mining exposes many hidden but not detectable by analyzing only the firewall policy rules, resulting in two new types of the anomalies. As a result of these mechanisms, network security administrators can automatically review and update the rules. We have developed a prototype system and demonstrated usefulness of our approachesK Golnabi, RK Min, L Khan, E Al-Shaer

  4. Firewall Policy Advisor for anomaly discovery and rule editing: Integrated Network Management, 2003. IFIP/IEEE Eighth International Symposium on (2003), pp. 17-30.Firewall s are core elements in network security. However, managing firewall rules, especially for enterprize networks, has become complex and error-prone. Firewall filtering rules have to be carefully written and organized in order to correctly implement the security policy. In addition, inserting or modifying a filtering rule requires thorough analysis of the relationship between this rule and other rules in order to determine the proper order of this rule and commit the updates. In this paper, we present a set of techniques and algorithms that provide (1) automatic discovery of firewall policy anomalies to reveal rule conflicts and potential problems in legacy firewalls, and (2) anomaly-free policy editing for rule insertion, removal and modification. This is implemented in a user-friendly tool called "Firewall Policy Advisor". The Firewall Policy Advisor significantly simplifies the management of any generic firewall policy written as filtering rules, while minimizing network vulnerability due to firewall rule misconfigurati on.ES Al-Shaer, HH Hamed

  6. Algorithms for analysing firewall and router access lists: (1999)Network firewalls and routers use a rule database to decide which packets will be allowed from one network onto another. By filtering packets the firewalls and routers can improve security and performance. However, as the size of the rule list increases, it becomes difficult to maintain and validate the rules, and lookup latency may increase significantly. Ordered binary decision diagrams (BDDs) -- a compact method of representing and manipulating boolean expressions -- are a potential method...S Hazelhurst
