Static analysis for verification of software program access to secure resources for computer systems
View Patent ↗Computer program products and apparatus are disclosed. Using a static analysis, a software program is analyzed to determine whether the software program accesses a secure resource for a computer system without verification that the secure resource can be accessed by the software program. In response to an access by the software program to the secure resource without verification that the secure resource can be accessed by the software program, a result is output indicative of the analyzing. An apparatus is disclosed that includes a user interface providing a security report to a user, the security report indicating a result of an analysis of whether or not a software program accesses a secure resource for a computer system without verification that the secure resource can be accessed by the software program.
1. A method, comprising:
using a static analysis, analyzing a software program to determine whether the software program accesses a secure resource for a computer system without verification that the secure resource can be accessed by the software program, wherein analyzing the software program further comprises determining whether a verification check is present for an access by the software program to the secure resource but where the verification check is invalid due to at least one of (1) a reference to the secure resource or (2) a method of access to the secure resource changing between verification by the verification check and access to the secure resource by the software program; and
in response to an access by the software program to the secure resource without verification that the secure resource can be accessed by the software program, outputting a result indicative of the analyzing.
2. The method of claim 1 , wherein the software program includes one or more of the following: source code, byte code, library modules, application code, or object code.
3. The method of claim 1 , where the verification is authentication.
4. The method of claim 1 , where the verification is authorization.
5. The method of claim 1 , wherein the analyzing is performed for any and all accesses to secure resources made in the software program.
6. The method of claim 1 , wherein the analyzing is performed prior to the execution of the software program on the computer system.
7. The method of claim 6 , further comprising preventing the software program from executing on the computer system in response to an access by the software program to the secure resource without verification that the secure resource can be accessed by the software program.
8. The method of claim 1 , wherein analyzing the software program comprises determining whether a verification check is missing for an access by the software program to the secure resource.
9. The method of claim 1 , wherein the computer system is one of the following: a client system, a server, or a mobile device.
