Methods of detecting malicious code injected into memory of a computer system are disclosed. The memory injection detection methods may include enumerating memory regions of an address space in memory of computer system to create memory region address information. The memory region address information may be compared to loaded module address information to facilitate detection of malicious code memory injection.

Information security techniques including detection, interdiction and/or mitigation of memory injection attacks

Techniques allow runtime extensions to a whitelist that locks down a computational system. For example, executable code is not only subject to whitelist checks that allow (or deny) its execution, but is also subject to checks that determine whether a whitelisted executable is itself trusted to introduce further executable code into the computational system in which it is allowed to run. In general, deletion and/or modification of instances of code that are already covered by the whitelist are also disallowed in accordance with a security policy. Accordingly, an executable that is trusted may be allowed to delete and/or modify code instances covered by the whitelist. In general, trust may be coded for a given code instance that seeks to introduce, remove or modify code.

Policy-based whitelisting with system change management based on trust framework

Techniques have been developed to allow runtime extensions to a whitelist that locks down a computational system. For example, executable code (including e.g., objects such as a script or active content that may be treated as an executable) is not only subject to whitelist checks that allow (or deny) its execution, but is also subject to checks that determine whether a whitelisted executable is itself trusted to introduce further executable code into the computational system in which it is allowed to run. In general, deletion and/or modification of instances of code that are already covered by the whitelist are also disallowed in accordance with a security policy. Accordingly, an executable that is trusted may be allowed to delete and/or modify code instances covered by the whitelist. In general, trust may be coded for a given code instance that seeks to introduce, remove or modify code (e.g., in the whitelist itself).

System and method are disclosed for securing and managing individual end-user platforms as part of an enterprise network. The method/system of the invention has three main components: a security module, a manager appliance, and a console appliance. The security module enforces the enterprise licenses and security policies for the end-user platforms while the manager appliance provides secure, centralized communication with, and oversight of, the security module. The console appliance allows an administrator to access the manager appliance for purposes of monitoring and changing the licenses. Security is established and maintained through an innovative use of data encryption and authentication procedures. The use of these procedures allows the appliances to be uniquely identified to one another, which in turn provides a way to dynamically create unique identifiers for the security modules. These various components together form an infrastructure over the enterprise network to securely manage the end-user platforms.

Method and system for license management

A system and method for network security using a kernel based network security infrastructure is disclosed. The method comprises the installation of a computer code set into the operating system kernel of each computer on a network and use of the computer code set to detect and stop unwanted or malicious intrusions into the kernel. Because the security feature is kernel based, a broader range of security features, such as security of communication between user-space applications and the kernel, can be implemented.
