Patent

CA 2600236

Methods, systems, and computer program products for firewall policy optimization are disclosed. According to one method, a firewall policy including an ordered list of firewall rules is defined. For each rule, a probability indicating a likelihood of receiving a packet matching the rule is determined. The rules are sorted in order of non-increasing probability in a manner that preserves the firewall policy.

L'invention porte sur des procédés, sur des systèmes et sur des produits de programmes informatiques s'appliquant à l'optimisation de la politique de pare-feu. Selon ce procédé, on a défini une politique de pare-feu comprenant une liste ordonnée de règles de pare-feu. Pour chaque règle, on a déterminé une probabilité indiquant une vraisemblance de réception d'un paquet correspondant à la règle. Les règles sont mises en ordre de probabilité non croissante de manière à conserver la politique de pare-feu.
