Source code security audits objectives
Static Application Security Testing (SAST) consists of, using a security tool, automatically analyzing the source code of a program, application or service in order to discover security issues without the need to execute it.
In code security audits, Tarlogic's team of experts tries to find possible vulnerabilities and security flaws in the source code using these static analysis techniques, a process commonly known as white-box auditing.
The result of this effort will allow the customer to gain an accurate and deep understanding of the security status of the analyzed source code.
Source code security audits benefits
- It has no impact on productive environments, since it is a static analysis.
- Our code security audit allows to discover a large number of vulnerabilities and bad development practices in a fast way.
- It allows a deep analysis of all possible source code execution flows.
Code audit general description
In code security audit, the software entire source code of a particular component or application is usually analyzed automatically using a SAST solution.
Once this information is available, false positive filtering is performed, usually with the help of the development team. The various bad practices of secure development that can be found in the source code are also discussed.
This information is then documented and presented in a report detailing all the vulnerabilities found, a brief description of each one and its possible solution.
Code review FAQs
How do you audit a code?
The code can be audited in two ways, either statically or dynamically, each way has its benefits and tools for performing the analysis.
To audit the code statically, the code itself and a SAST (Static Application Security Testing) tool are needed. The SAST tool shall be able to interpret the language in which the code is written and shall have rules to identify vulnerabilities in that language.
Finally, an analyst reviews the results to validate that results don’t include false positives, try identify false negatives, and to complement the information provided by the tool, for the developers to have a better understanding of the vulnerability.
What is the purpose of a code audit?
Identify as many vulnerabilities as possible in the most effective way, and before they are exposed in a production environment. This avoids the risk of exposing a high-impact vulnerability.
It also avoids the effort of mitigating a vulnerability that may affect several application modules at a late stage of the software lifecycle where the code is fully developed and changing the core or main modules may lead to a bottleneck task where too much application logic is modified.
What does a code security audit include?
A static code audit includes the analysis of the code using a SAST (Static Application Security Testing) tool that is appropriate for the programming language and/or framework that makes up the code.
Results are reviewed by an analyst, and the security status of the application is presented to executives and technical responsible of the application, using specific formats. The objective is to provide valuable data to help planning actions needed to correct vulnerabilities and improve security.
