A system and method providing Internet protocol security without secure domain name resolution are disclosed. A processor that periodically needs to resolve domain names into network addresses has a local DNS server that includes a secure IPSEC cache, a resolver function, a security policy database, and an IPSEC layer. The cache is readable only by the IPSEC layer. Resolved domain names are cached with process and transaction identifiers that uniquely associate the resolved names with an application process and time. When resolution is needed, the cache is used to ensure that IP addresses are resolved from names that came from the application. As a result, IPSEC connections may be established without use of DNSSEC to provide secure domain name resolution.

The terminal is capable of communicating with a VPN client and at least one application. The VPN client, in turn, is capable of defining at least one VPN access point, each VPN access point including an associated physical access point and VPN policy. Thereafter, the VPN client can access at least one VPN based upon the VPN access point(s) to thereby establish at least one data connection from at least one application across the at least one VPN. In addition, the VPN client can be capable of downloading at least one VPN policy from the SPD. A system for managing at least one Virtual Private Network (VPN) policy is also provided, where the VPN polic(ies) are for use in accessing at least one VPN.

A searching method for a Security Policy Database (SPD) is proposed. The characteristic of peer gateway of the IPSec is applied to divide the original SPD into multiple smaller peer-based SPDs, and build a peer table corresponding to the peer-based SPDs. When it is required to search the policies in the database, the peer-based SPD according to the present invention can be directly used so as to save the time of data searching.

Security policy databases capable of being fast retrieved while securing sequentiality. An IPSec processing device of the present invention performs communications by encrypting IP packets exchanged between a first IP network and a second IP network. The IPSec processing device includes a security policy database that stores security policies. The security policy database includes first, second, and third security policy databases. The first and third security policy databases include a linear list structure, and the second security policy database includes a hash list structure. The IPSec processing device, when performing at least one of transmission and reception of the IP packet, retrieves a security policy in the order of the first, second, and third security policy databases.

The invention relates to a system and method for dynamically configuring a virtual machine migration security policy. A source host node and a target host node are both provided with strategy agent modules; a security policy database and a policy coordination module are respectively connected with a security management center; the policy coordination module is further connected with all the strategy agent modules; the security management center is used for inquiring the security policy database to judge whether a local security policy intermediate value violates a global security policy or not; if yes, the local security policy intermediate value is adjusted to be a security policy final value; if not, the local security policy intermediate value is set to be the security policy final value. Due to the fact that the global security policy is introduced in the process of generating the security policy final value, the security policy final value can violate the global security policy under no circumstances; after a virtual machine is migrated, a local security policy on the target host node is adjusted and brought into global security policy planning, and therefore the virtual machine is effectively prevented from lowering in security before and after migration.

The invention relates to the field of firewalls, and aims to provide an HTTP (Hyper Text Transport Protocol) service firewall based on an adaptive agent mechanism. The HTTP service firewall based on the adaptive agent mechanism comprises an agent module, a core control and a security policy database, wherein the agent module is used for accessing HTTP access from a client, acquiring various data, transmitting the acquired data to the core control, and performing execution after receiving a judgment conclusion of the core control; the core control is used for scheduling the cooperation of each module, receiving the request of each module, and updating data records, working modes and working methods in the security policy database; and the security policy database comprises a client permission strategy, a client session state database, a start address white list and a subsequent address white list. Through adoption of the HTTP service firewall, checking work on various security aspects of accidental access, accidental parameters, session parameter check, user associated data and the like needing to be considered in a protection system can be reduced, and the security level of the system is raised.

A security policy database cache includes at least one primary table including signature values that indicate that a packet's security policy database information may be in the cache and at least one secondary table including cache entries having a selector, flags, security association information and an operation to perform on the corresponding packet for which a cache lookup was made.

A security procedure for invoking IPsec security for communication of a packet in a network includes the steps of generating a message to be sent at the transport layer, building Internet Protocol and Transport Control Protocol headers for the message, selecting a security policy in accordance with a security policy database after the step of building Internet Protocol and Transport Control Protocol headers, and processing the packet according to the selected security policy.
