IPSec rules are searched in an improved manner to reduce processing overhead. For selected connectionless protocols, packets are treated as if they were part of a simulated connection. A pseudo-connection memory block is allocated with the creation of each socket and IPSec security binding information is stored in the pseudo-connection memory block on a first packet. Thereafter, as long as the source address and port in incoming packets on the same socket or destination address and port in outgoing packets on the same socket remain the same, the packets are treated as part of a simulated connection. The security rules are not searched again until the simulated connection terminates or the static rule table is modified. In the preferred embodiment, security binding is made only to the static rule or placeholder.

Ipsec rules are searched in order from rules containing the most specificity to those containing the least specificity of attributes. The static rules include placeholders for sets of dynamic rules. Dynamic rules are searched only if a placeholder is the first matching rule in the static table. Sets of dynamic rules are partitioned into separate groups. Within each group there is no rule order dependence. Each such group is searched with an enhanced search mechanism, such as a search tree. For connection oriented protocols, security rule binding information is stored in association with the connection. This allows the searching of the rules to be performed only when a connection is first established. If a static or dynamic rule is changed during a connection, a search is repeated. For selected connectionless protocols, packets are treated as if they were part of a simulated connection.

Ipsec rules are searched in order from rules containing the most specificity of attributes to those containing the least specificity of attributes. The static rules include placeholders for sets of dynamic rules. The placeholders in the static table immediately precede and point to an associated set of dynamic rules. Dynamic rules are searched only if a placeholder is found to be the first matching rule in the static table. Sets of dynamic rules are partitioned into separate groups. Within each group there is no rule order dependence. Each such group is searched with an enhanced search mechanism, such as a search tree. Searching is further improved by searching at layers higher than the IP layer.

Methods, systems and computer program products provide for recovering from the failure of a primary distribution processor which provides secure communications over a network in a distributed workload environment having target hosts which are accessed through the primary distribution processor by a common network address. Information sufficient to restart communications through the primary distribution processor utilizing network security is provided to a backup distribution processor. Failure of the primary distribution processor is detected and the communications utilizing network security restarted at the backup distribution processor utilizing the provided information. Both inbound and outbound communications with target hosts utilizing the common network address and which are associated with a secure network communication are then routed through the backup distribution processor. Both inbound and outbound processing of secure network communications utilizing the common network address is performed at the backup distribution processor so as to provide network security processing of communications from the target host and network security processing of communications to the target host.
