Why Static Code Analysis is Necessary

Static Code Analysis examines the source codes of an application without the need to actually execute the program. This is also referred to as white-box testing method where the codes are evaluated to check for any potential flaws and mitigate possible program threats such as bugs and security vulnerability. The static code testing is considered as an effective tool that helps predetermine the software’s flaws which may not be detected by the dynamic testing methodology alone.

Typically, the static analysis is executed during the Security Development Lifecycle or SDLC implementation phase. Here are someof the essential functions or uses of static code analysis:

  1. To Develop a Standardized Coding SystemWhen using static codes analysis, programmers tend to develop coding convention and standards within the team thereby achieving code uniformity. As coding is standardized, it provides an advantage for future developers to be able to easily understand the source codes along with their functions.
  2. To Implement Code DocumentationIntegrating static analysis often requires code documentation.
  3. To Diagnose Potential Security Flaws

Using the advanced static code analysis tools and models it is much easier to predetermine potential security issues which a human programmer may miss out. Various security flaws such as SQL Injections which can compromise passwords and secured data and Cross-site Request Forging can be major headaches if not identified early on.

The use of static code analysis before a software or application is deployed to production and the actual operation is considered one of the best practices to enhance software security, quality and reliability. The practice has long been used by various programmers and software engineers and is found to be greatly beneficial in that:

  1. It provides thorough analysis and evaluation of the source codes.Using static analysis in your project gives you the opportunity to extensively examine the codes without necessarily executing them.
  2. It sets boundary and standard rules to the project.Static analyzers such as “findbugs” and “fortify” are among the commonly used static analysis tools and are efficient tools in implementing specific project rules. In an event that one of the programming team forgets or misses out in any of the set standards, the policy violations and mistakes will be highlighted by these analyzer tools.
  3. It allows early detection of bugs and threats.Using static code analysis during the application’s development cycle is one of the most effective ways to uncover potential bugs and security threats that may compromise the software later on. This is probably one of the highlights of static analysis tools. The earlier program bugs and security threats are detected, the better. It would cost less time and resources to fix them and it can prevent extensive damage to the software.
  4. It greatly enhances the software security.

Integrating static code analysis helps reveal the software’s security flaws and vulnerabilities. Static analyzers offer comprehensive analysis exposing security issues that may potentially compromise the entire application. With static code analysis, the application’s reliability and quality is greatly improved.
