SAST is a type of software security vulnerability testing.
SAST tools include static code analyzers. They inspect and analyze an application’s code to discover security vulnerabilities.
SAST can be performed at all stages of your software development — on the desktop, within CI/CD Pipelines, and server nightly builds. This helps to ensure that software vulnerabilities are detected earlier in the process.
Why Automated Security Testing Tools Are Necessary
Cyberthreats are growing. Automated security testing tools — like SAST — are now an essential part of application development. You can use them to safeguard your software from potential vulnerabilities.
The Differences Between SAST and DAST
Ensuring that your software is secure and safeguarded against vulnerabilities is easy with the right software security tools and techniques — like SAST and DAST.
NIST Cybersecurity Framework Overview
NIST provides a cybersecurity framework. Use NIST to better understand and improve how you manage cybersecurity risks.
The NIST cybersecurity framework is composed of three components:
- Framework Core
- Implementation Tiers
- Framework Profiles
Secure Coding Overview
Secure coding is an important part of SAST.
Code that is secure makes it more difficult for hackers to take direct control of a device or gain access to another device. You need to incorporate secure coding practices throughout software development to ensure secure code.
The best way to ensure secure coding is to use a static code analyzer. By using a static code analyzer, you are able to enforce coding standard rules and flag security violations.
Application Security (AppSec) provides guideance on how to ensure secure development throughout the wholee lifecycle, including after thee application has launched.
Secure Coding Standards Overview
Secure coding standards are rules and guidelines used to prevent security vulnerabilities. They prevent, detect, and eliminate errors that could compromise software security.
Secure coding guidelines are especially important for embedded development — which relies on C/C++ coding languages. They're also important for enterprise software — which relies on C# and Java coding languages.

Secure Coding Best Practices
Following secure coding best practices helps to ensure that code is safe from threats and free of vulnerabilities.
The most effective way to implement secure coding standards is to use an automated security testing tool — like SAST. Half of all security defects are introduced at the source code level. That's why it is essential to enforce coding standards to identify code security vulnerabilities early.
Guide for Secure Software Development
Beginning a new software project can be daunting, as there are many decisions that need to be made and considerations that must be thought through. To help, we've put together a step-by-step guide to walk you through the most time-consuming and difficult challenges of a new project to help ensure that yours is a success.
SAST Tutorial to Prevent Cybersecurity Threats
Unfortunately, cybersecurity threats will continue to be a concern. You need to take steps to safeguard your software from potential vulnerabilities.
The Top Cybersecurity Vulnerabilities for Embedded Software
A single cybersecurity vulnerability can leave embedded systems defenseless to data breaches, cyberattacks, and other cyber incidents. Unfortunately, cybersecurity vulnerabilities are an ever-present threat. You need to know how to identify and fix these vulnerabilities to help ensure that your embedded systems are secure.
Understanding the Difference Between Software Safety vs. Security
Safe software depends on the quality of the safety and security of the code to protect against malicious attacks. While code security and safety are often used interchangeably, there are differences between the two.
Code security is about preventing unwanted or illegal activity in software. It helps to ensure that our systems are secure during an attack. While code safety is a broader term used to indicate whether the software is safe and reliable to use.
The Most Common Software Vulnerabilities
Software vulnerabilities can impact the performance and security of your software, and could allow untrustworthy agents to exploit or gain access to your products and data.
How to Apply This SAST Tutorial to Specific Industries
SAST helps to ensure that the software is safe and secure from potential cyber vulnerabilities. While SAST is more applicable to some industries, every team can benefit from their regular use.
To better explain how SAST can help, here is an example of how SAST helps medical device development.
Medical devices must be compliant with FDA cybersecurity guidance. Automated security testing tools — especially SAST — are essential to enforcing coding rules and ensuring that code cannot be exploited by cyberthreats.
Which Automated Security Testing Tool to Use
To develop secure and safe software, you need the right automated security testing tool — like SAST.
Automated security testing tools should help you:
- Identify and analyze risk and help prioritize severity.
- Fulfill compliance standard requirements based on risk (and prove it).
- Apply a coding standard and ensure that coding rules are followed.
- Verify and validate through testing.
- Achieve compliance and get certified faster.
