20130276098 | Method and Computer Device for Handling COM Objects - A computer device and method are provided to handle COM objects. A COM creating unit intercepts a request for creation of an elevated COM object by a first user process, determines whether the first user process is entitled to access the COM object, and creates the COM object without elevated privileges. A COM implementing unit intercepts a second user process that implements the COM object, confirms that the second user process is entitled to access the COM object and elevates the privilege level of the second user process to implement the elevated COM object. | 10-17-2013 |
20130061320 | Computer Device with Anti-Tamper Resource Security - A computer device provides an execution environment that supports a plurality of processes. A plurality of key resources are associated with a security application that may perform process elevation to grant privileged access rights to a user process. A security module controls access to the key resources using an access control list. An anti-tamper mechanism creates a protection group as a local security group and adds a deny access control entry to the access control list. The anti-tamper mechanism intercepts the user process and creates a revised access token identifying the user process as a member of the protection group. The security module matches the protection group in the revised access token of the user process against the deny access control entry in the access control list of the key resources thereby restricting access by the user process even though the user process otherwise has privileges to access those resources. | 03-07-2013 |
