Best Secure Code Training Tools

Writing code and creating applications is a form of art. Developers put their best effort into creating a solution that is not only useful but also secure to use

Despite their best efforts, there is always a chance that human error could lead to vulnerabilities leading to costly system crashes and data losses.

The best way to prevent such vulnerabilities from occurring is with the help of secure code training tools.

Here is our list of the best secure code training tools:

Now, although we will soon have a detailed look at each one of them, here is a brief list of some of the best secure code training tools:

  1. SonarQube EDITOR’S CHOICE A popular open-source platform for continuous code monitoring; catches issues like null-pointer references, logic errors, and resource leaks and also boasts compatibility with an extensive array of programming languages.
  2. Synopsys Coverity An open-source tool that is compatible with languages (and flavors) like C, Java, Ruby, PHP, and Python; it also supports 100 compilers; the tool delves deeper to find root causes of errors for easier debugging and error-fixing.
  3. DeepSource A cloud-based code tracking tool for security-conscious developers who prefer to play their cards close to their chests; it is fast, easy to install, and makes it easy for teams to collaborate on keeping their code secure.
  4. VisualCodeGrepper This is the “pocket knife” version of the code analysis tool. It holds just the essential tools required to complete the task effectively without confusing users or overburdening the system; it can be configured to work with any programming language using a simple CONFIG file.
  5. Embold An essential code analysis tool for code quality management; it helps improve developers’ security capabilities by teaching them about best practices in secure coding with the help of complex issue visualizations.
  6. Parasoft A tool that supports various types of static analysis techniques to ensure code security compliance; it packs sub-tools for securing languages like C++, Java, and .Net to help cover the most popular languages used in the business environment.
  7. Checkmarx This is another comprehensive platform for tackling various aspects of code security; it includes security testing, composition analysis, and application security testing to make sure code is covered from all angles.

But, what is a secure code training tool?

A secure code training tool is a software solution created to help programmers and developers write code that is as bug-free and error-free as possible. These types of solutions typically read the code as written, analyze it, and identify potential issues or vulnerabilities in real-time. This allows the coders to fix their work before it is released into the production environment.

Using secure code training tools helps avoid what could turn out to be costly coding mistakes and saves time and money wasted on correcting errors in programs that have already been released into the production environment. And, over time, the developers themselves learn how to develop applications that are secure and compliant to industry security standards – the first time around.

Feature of a good secure code training tool

Our methodology for selecting an excellent secure code training tool

  • It should accommodate as many programming languages as possible – especially if it is being deployed in a large development environment.
  • It should also integrate well with the libraries, frameworks, and platforms in the IT architecture it is being deployed on.
  • Next, it should integrate into the IDE that the developers use and not run independently or on the side as a stand-alone software or application.
  • It should be able to detect weaknesses, in real-time, from snippets of code and not only the buildable source code; in fact, an excellent secure code training tool will be able to read code in its source version and not just the binary, compiled format.
  • It should detect as many vulnerabilities as possible – it should keep up with new bugs and threats as they come out; a good sign would be its ability to see the top ten Open Web Application Security Project (OWASP) threats.
  • It should be precise – its accuracy should be high enough to avoid false-positive and false-negative detections; it shouldn’t add to the confusion.
  • It should be easy to set up, use, and administer – and once installed; it should be run continuously and automatically with minimum manual intervention required, if at all.
  • Finally, any tool should always be worth the investment – it doesn’t make sense to pay dearly for a performance that can be out-matched by that from a free or cheaper alternative solution.

The tools we are about to see next have all or most of the features we have just seen, making them stand out from the crowd.

Synopsys Coverity is another open-source secure code training tool that works with C, C++, C#, Objective-C, Java, JavaScript, Node JS, Ruby, PHP, and Python. It also supports 100 compilers. What’s interesting is that this tool doesn’t just point out issues with code – it delivers clear descriptions of their root causes.

Key Features:

  • A Long List of Programming Languages: Supports 100 compilers
  • Active During Coding: Integrates with a development environment
  • Highlights Errors: Shows programmers where changes are needed
  • Deployment Options: Integrates into IDEs

Why do we recommend it?

Synopsys Coverity is a static application security testing (SAST) service. This examines the code for a We application and identifies security weaknesses. It is like a vulnerability scanner for code, which plugs into the IDE and spots errors as they appear. The tool provides remediation tips and training articles, linked to the discovered problem.

Some examples of issues that can be tracked and monitored with Coverity include resource leaks, NULL pointers, incorrect use of APIs, using uninitialized variables, memory corruption, buffer overrunning, control overflows, oversight in error handling, insecure data, and more. And it’s not just the issues – the tool finds the root causes of each error for easier debugging and error-fixing; this cuts down the time wasted on troubleshooting and error resolution.

While Coverity works in real-time – thus enabling developers to find and fix security and quality defects as they are writing their code – it also quarantines any existing defective code while under examination, so it isn’t executed until it has been debugged cleared.

This is a fast and accurate tool that runs incremental analysis in the background, making it inconspicuous while it catches bugs in real-time; it helps the developer realize the severity of any issues using Common Weakness Enumeration (CWE) information, offers remedy recommendations, as well as relevant security training – all from within the IDE.

Synopsys Coverity comes in two versions – on-premises to be used in high-security development environments and as a SaaS in the cloud for more straightforward deployment and code control. It supports and integrates with over 70 frameworks, including ASP .Net, VB .Net, Android, Salesforce, and more.

Who is it recommended for?

Why do we recommend it?

DeepSource is another SAST, however, unlike Synopsys Coverity, this tool doesn’t interact with the programmer. Rather, it is a tester that can integrate into the CI/CD pipeline. As well as generating a report of errors, the tool will straighten the formatting of a program and fix the discovered security errors.

This tool is deployed on-premises, making it the ideal choice for security-conscious developers who prefer to keep their source code on their servers. DeepSource integrates with code collaboration platforms like GitHub, Bitbucket, and GitLab; it also works with programming languages like Python, Ruby, and Go.

The tool has an impressive database to compare issues with – it can detect over 2,000 issues in a code database. It automatically formats code on every commit and runs existing code formatters without breaking continuous integration (CI) builds.

It is an ideal tool for collaboration. It has private repositories that can be shared between teams; alternatively, the teams can use public repositories to share code among themselves and across the board.

It has a dashboard where teams have reports and insights, allowing them to monitor their codes’ quality and overall health; they can also keep track of code metrics like documentation coverage and dependencies. DeepSource has a high accuracy rate – with a less than 5 percent false-positive rate – it does its job without interfering with the overall performance of teams and their digital assets.

Who is it recommended for?

This package is appealing for development companies that have large teams and a high code throughput. The autofix function could be a little risky. However, if you deploy a Web application vulnerability manager for your live systems, you will know whether you can trust the abilities of the tool.

VisualCodeGrepper is a well-maintained open source system. Although this tool seems to be the product of just one person, he seems to know what he’s doing because he has done the world a favor by creating this free tool. The software runs on Windows and identifies OWASP-listed vulnerabilities.

It is an uncomplicated tool with only the essential tools required for conducting analysis when time is of the essence. And yet, it can perform complex checks like identifying everything from broken code to any overflows. This tool has a CONFIG file for each language where developers can add bad code and functions or any other text representing the programming issues they want to search for.

For example, it can be configured to find phrases like “To Do” and “Fix Me” left within comments which could indicate broken code; it also provides stats and pie charts – for individual files or the entire codebase – that show relative proportions of code, whitespaces, comments, and bad code.

Apart from the common programming languages, VisualCodeGrepper is intelligent enough to analyze legacy or older languages like COBOL – all that is needed is to specify the language being used.

The tool can run multiple scanning processes, regardless of the complexity of the project, and display results individually for better analysis; these results show the possible errors, security flaws, the number of comments involved, percentage of the whole project, and potentially unsafe flags or code found in each process.

Who is it recommended for?

This tool will scan C++, C#, VB, PHP, Java, PL/SQL, and COBOL code. Although it is a very competent tool, you don’t get a professional support package, so if your business insurance requires that, you will need to look elsewhere.

Secure Code Training FAQs

What is secure code training?

Although you can get training courses for Web application programming, training is another matter because it involves hands-on work while still earning. The number of security weaknesses that can exist in a Web application is vast and developers can learn general categories of mistakes to avoid but they will never get a full knowledge of every potential exploit. Therefore, most secure code training packages are code scanners that highlight changes that need to be made.

Why secure code training?

Secure code training is a form of Web application security scanning. Rather than automatically fixing problems or indicating that problems exist, secure code training packages show the exact lines of code that need to be changed and explain why. This helps developers learn as they work.

What is secure coding tools?

Secure code training tools are available in a number of formats. Some are integrated into the development environment and will highlight errors as each line of code is written. Other tools are activated during the testing phase of a completed Web application and, if errors are discovered, send the application back for rework with notes on how it should be adjusted. These tools prevent security weaknesses from going live, while also showing developers how to improve their code.
