Source Code Audit Review Service
Our innovative methodology to audit the source code of an application provides a comprehensive framework to identify the flaws and the security issues present inside the source code of the application. Here, we not only rely on the automated tools for the auditing process, but also perform manual method of auditing the source code of the application according to the standard defined.
The team at SecureLayer7 firstly identifies the attack surfaces of input. Then they determing whether the existing security mechanisms are in place or not. After identification of these attack surfaces, we need to analyze the qualitative aspect according to the specific programming behaviour which includes user supplied input assumptions, unsanitized user supplied inputs, checking of functions return values, variable initialization check. It also includes performing check for jump or function pointers use of user supplied data, needs to be investigated.
The check for annotations can be done with the help of qualitative analysis of the source code. By using formal method of auditing, we need to check for the precise functioning of the program objective and verify and validate the output according to its implementation based on mathematical logic. For verifying the correctness of the syntax being used i.e. non formal method, we need to define various parameters manually as well as in form of input based for automation tools.
Source Code Audit Process
The first step of a security code review is to conduct a through study of the application followed by the creation of a comprehensive threat profile.
Our experts study the code layout to develop a specific code reviewer plan, and uses a hybrid approach where automated scans are verified and a custom manual review is performed.
Once the code is analyzed, the next step in the security code review process is to verify existing flaws and generate reports that provide solutions.
