System and method for using virtual local area network tags with a virtual private network

An exemplary system and method for using a network access system, such as a virtual private network (VPN), are provided. A user device may have a user session with a home agent. Additionally, an initiating security gateway may be in communication with the home agent, and a terminating security gateway may be in communication with the initiating security gateway via a tunnel (e.g., Internet Protocol in Internet Protocol (IP-in-IP) or Internet Protocol security (IPsec) tunnel). Further, a virtual local area network (VLAN) tag associated with the user session may map to a selector operable in a security policy database. The selector may be used to find a security policy defining an IPsec procedure, and the security policy may be applied to the tunnel. Also, the initiating security gateway may also include a Quality of Service (QoS) module that determines QoS markings for a packet traveling along the tunnel.

Process and system providing internet protocol security without secure domain resolution

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.

Analyzing security compliance within a network

A security policy database identifies the intended security policies within a network, a traffic generator provides test traffic that is configured to test each defined security policy, and a simulator simulates the propagation of this traffic on a model of the network. The model of the network includes the configuration data associated with each device, and thus, if devices are properly configured to enforce the intended security policies, the success / failure of the simulated test traffic will conform to the intended permit / deny policy of each connection. Differences between the simulated message propagation and the intended security policies are reported to the user, and diagnostic tools are provided to facilitate identification of the device configuration data that accounts for the observed difference. Additionally, if a network's current security policy is unknown, test traffic is generated to reveal the actual policy in effect, to construct a baseline intended security policy.

Packet communication system

A packet communication system for effectively using network resources and for improving network operability. A transmission security policy database specifies the omission of header information attached when a transmission packet is capsulated, as a transmission security policy. A header-information omitting section omits the header information of the capsulated transmission packet. A packet transmission processing section adds a security header and a header for tunnel communication to the packet from which the header information has been omitted and transmits the packet. A receiving security policy database specifies that the header information has been omitted, as a receiving security policy. A header-information recovering section searches the receiving security policy database for a security policy for a received packet, and when recognizing that the received packet is a target packet from which the header information has been omitted, recovers the header information.
