Best static code analysis tools

Developers love writing code – they have to. Otherwise, they wouldn’t have chosen their profession. But, if there is one thing that can make their lives miserable, it is an error message throwing their new applications into chaos. And nothing is more frustrating to them than not being able to track the cause of the bugs

That is why they need the seven best static code analysis tools we are about to see.

Here is our list of the seven best static code analysis tools:

What is static code analysis?

Let’s define static code analysis:

Static code analysis – also known as Static Application Security Testing or SAST – is the process of analyzing computer software without actually running the software. Developers use static code analysis tools to find and fix vulnerabilities, bugs, and security risks in their new applications while the source code is in its ‘static’ state – meaning when it is not being run.

This process helps reduce exposure to internal and external security risks, allows developers to create applications quickly, and lets businesses see where they stand concerning compliance to industry security standards.

Note: To find out more about SAST, you can refer to “What is SAST (Static Application Security Testing)?” – This is a post that gives a comprehensive insight into the technology itself.

This is all in contrast to Dynamic Application Security Testing or DAST, where the analysis occurs while the application is running.

What makes for a tremendous static code tool?

Businesses and developers should consider the following factors when comparing and choosing static code analysis tools:

  • Low false-positive rates – a question is what volume of false positives users of a product encounter. Their tool should help them save time, not waste it chasing issues that don’t exist. Also, the tool should make it easy to manage false positives, regardless of how low the rate of occurrence, when they do (inevitably) encounter them.
  • IDE Integration – users should be able to integrate their tools into their existing developer environments. This is critical in measuring how early in the software development life cycle (SDLC) the tools can be used; the earlier it can be used, the more effective it becomes.
  • The extent of automation – they should also ask to what extent the static testing can be automated within the development environment. Incidentally, SAST has traditionally been considered one of the more manually-driven security testing methods. Any level of automation improves efficiency.
  • Detailed reporting capabilities – developers should be able to figure out where they have gone wrong quickly and then fix the issues without resorting to more research. A good tool will not only highlight errors but also provide ample documentation and training for better understanding and directly contributing to the resolution of issues.
  • The price – the price of a SAST should be worth the tool’s performance and its features. After all, why pay for any product when there is a better alternative on the market for free?

Advantages of using a static code analysis tool

We have just had a look at the seven best static code analysis tools. Let’s now see why developers and businesses should adopt these solutions:

  • With the help of SAST solutions, the development of applications becomes faster while applications become more secure and reliable.
  • Businesses have their applications up and running in the shortest amount of time; they save time and money – and release more secure code on time – all factors that help their processes become more efficient.
  • These tools help create better developers who develop code quickly and do it without making security risks or deviating from industry best practices.
  • They also don’t waste time by having to retro-fit security into old code – they do it while it is being built; they have code insights before execution.
  • SAST tools execute scans quickly when compared with dynamic analysis (DAST), for example.
  • The search for bugs and code quality maintenance is automated, which quickly eliminates human error due to manual debugging.

Static vs. Dynamic code analysis

A point that needs to be addressed is why developers prefer to choose static code analysis tools (SAST) over dynamic (DAST).

For one, SAST tools debug the code as it is being created and before it is built. This makes it quicker and easier to clean the code. They also give developers educational feedback and the chance to fix the code themselves; this can serve as hands-on training.

DAST tools, on the other hand, fix the code by giving security teams quickly delivered improvements. But, unfortunately, they are comparatively resource-intensive and require more expertise to run.

Static code analysis tools are a must

Businesses and their developers should always have static code analysis tools integrated into their development process. It is the best way to turn code into applications that contribute to business processes without creating any risk.

Static code analysis FAQs

What is static code analysis tools?

Static analysis scans through source code looking for coding errors or potential security weaknesses. The practice is also known as source code analysis. Traditionally, source code checking is the responsibility of the coder – it is expected that such mistakes should be corrected in order to sign off the coding job as complete. While testing is traditionally performed by running a program, source code analysis can be performed before a program has been completed, giving it the advantage of catching errors early. The use of static analysis for security weakness detection increased the importance of this field of QA and implementing the practice through automated tools removes human oversight and maximizes the efficiency of expensive human resources.

What do static analysis tools analyze?

Static analysis tools are useful for catching coding errors early. They can operate before unit testing is possible. Automated tools do not need to be limited to looking at the program in isolation but can highlight potential security issues that might arise once the code is implemented on specific operating systems or integrated into other applications.

Who typically use static analysis tools?

Static analysis tools are used to identify coding errors and so they are particularly useful to programmers during the creation of a program

Unit testing and acceptance testing can identify procedural errors with programs by running them. However, using static analysis first with an automated tool can spot common errors quickly and recycle programs for correction before time-consuming system testing occurs.

Not every organization is security-conscious and a new application can gather sales despite the presence of security weaknesses. The use of static analysis tols during the assessment of a software bundle for acquisition can be a useful way to identify insecure systems before a business commits to buying it.

New vulnerabilities arise all the time and so a function that passed security testing at acquisition could provide weaknesses later, particularly when applied in new suites and environments. Static code integrated into operation procedures, such as within a vulnerability scanner, can spot new vulnerabilities in old code.
