A dynamic protection system can analyze a computer system to determine its vulnerabilities to attack and generate a policy for protecting the computer system based on the identified vulnerabilities. Data received by the computer system can be analyzed to determine if it poses a threat to the system. This can prevent the data from entering the system or host based on a determination that the data poses a threat. Also, the dynamic protection system can receive policy updates to allow it to protect the system more efficiently and effectively. In other words, the dynamic protection system can protect an evolving computer system operating in an environment that is characterized by constantly changing methods of attack. Furthermore, by minimizing a need for manual intervention, attacks can be rapidly and accurately detected with a minimization of false positives, thereby lowering the cost of operation.

Attacks by computer viruses, worm programs, and other hostile software ('malware'), have become very serious problems for computer systems connected to large communication networks such as the Internet. One potential defence against such attacks is to employ diversity-that is, making each copy of the attacked software different. However, existing diversity techniques do not offer sufficient levels of protection. The invention provides an effective diversity solution by applying tamper resistant software (TRS) encoding techniques, to the communications that take place between software components, with corresponding changes to the code handling those communications. These communications may include, for example, data passed between software routines via parameters or mutually accessible variables, light-weight messages, signals and semaphores passed between threads, and messages passed between software processes. Effective TRS encoding techniques include data-flow encoding and mass-data encoding techniques.

A tamper detection system includes a trigger mechanism system and a detection circuit that operate in combination to protect an integrated circuit from attack. The detection circuit connects to the trigger mechanism system that is basically a protective mesh that consists of two separate loops of wire held in close proximity to each other and an optional ground layer. The mesh is such that an attempted penetration is highly likely to cause an open of either loop or a short of one loop to the other. The detection system recognizes shorts and opens in the mesh. The detection circuit is intended to be very simple in its operation it that it does not require a sophisticated stimulus and response set to operate. It is designed to be polled on a regular basis for indications of a change in its operation.

A challenge-response method and apparatus to defend a system against Denial of service (DOS) / Distributed Denial of Service (DDOS) attacks, especially resource consumption attack, the method including: before committing resources to a client, throwing a challenge to the client, verifying a result generated by the client, and committing resources only if the verification is successful. When the client mounts an attack against a server by throwing multiple requests, the server will throw multiple challenges to the client and the client will get overloaded in resolving challenges thrown by the server as the server is able to control a cost of the challenge and verify responses generated for the challenge by investing minimal resources. Thus, the server's resources are free for legitimate users.

Protection of an authentication password stored in a database held by a SAM of Windows® is strengthened. A GINA, a part of the OS, receives an authentication password in ASCII codes. The authentication password is converted to first UNICODES, and the first UNICODES are salted with a random number and converted to second UNICODES. The random number used for salting is associated with a user account and a password and stored in a read / write protected non-volatile memory or a non-volatile memory which can be accessed only by a BIOS. An LSA of the OS can process UNICODES without being changed.
