A system and method for capturing non-forgeable packet traces. Upon start-up of a sniffer, a first quote of Platform Configuration Register (PCR) values in a Trusted Platform Module (TPM) utilized by the sniffer is obtained, wherein the first quote comprises a list of starting values in the PCRs and is signed by the TPM and stored in a packet log. When a packet of interest is intercepted by the sniffer, the sniffer obtains a hash of the packet and instructs the TPM to extend a PCR with the hash value. The packet of interest is then stored in the packet log. When the sniffer is shutdown, a second quote of values in the PCRs is obtained, wherein the second quote comprises a list of current values in the PCRs, and wherein the second quote is signed by the TPM and stored in the packet log.

Notarizing packet traces

A method and system are provided to classify and convey data to satisfy a client request. The classification system is a two dimensional data classification system, including a first dimension pertaining to subject matter and a second dimension pertaining to data security. A partition is dynamically created, and data that satisfies the request populates the created partition to convey parsed data based satisfying both dimensions of the request.

Classification separation router

In a software environment wherein one or more subjects respectively seek to access one or more objects, and wherein a security policy having rules is associated with the environment, a method is provided for use in connection with an effort by a particular subject to access a particular object. The method comprises identifying a domain to which the particular subject belongs, and identifying a type that includes or characterizes the particular object. One or more rules of the security policy are then used to decide whether to permit the particular subject to access the particular object. The method further comprises providing one or more distinct audible sounds for a user associated with the particular subject, wherein each audible sound represents specified information pertaining to the decision of whether or not to permit access to the particular object.

Improving comprehension of information in a security enhanced environment by representing the information in audio form

A system for creating a non-reputable chat log. An initial quote is performed of a value of a register in response to a secure chat session being initiated. The value of the register is extended to record a message measurement within the register for the secure chat session in response to a message being measured. A final quote is performed of the value of the register in response to the secure chat session being terminated.
