As the world becomes increasingly more digitized, the security of our data and applications becomes more and more important. In this blog post, we will discuss two types of security testing that are crucial for the safety of web and mobile applications: SAST and DAST. We will also explain the importance of SAST and DAST and how they can help protect your data.
What Is Application Security Testing?
It entails evaluating and improving the security posture of applications (such as websites and mobile apps) to safeguard them from threats that can cause harm or loss of data. Companies need to develop secure applications so hackers don’t have access to confidential information or customer data.
Why Is Application Security Testing Crucial?
Application security testing is used to ensure safe and secure software applications. It helps organizations identify potential vulnerabilities before they are exploited by hackers, which can save money on repairs and lawsuits due to data breaches.
Additionally, it allows developers to build safer programs that don’t expose users’ personal information or cause other issues like identity theft or credit card fraud.
Security Issues With Web And Mobile Applications:
There are many types of security threats that applications can face, but the most common include:
- Malicious code – Code that is inserted into an application with the intent to harm or take control of a system. It is difficult to spot and may result in significant damage.
- Cross-site scripting – This is where malicious scripts are injected into a website via input fields. Once the script has been executed, it can be used to steal cookies and other sensitive information from users who visit that site. These attacks are most often employed against insecure websites.
- Injection flaws – When an application accepts input from users without properly verifying it, attackers can use this to inject malicious code into the application and databases. Injection flaws are one of the most prevalent types of security bugs, and detecting and correcting them may be tough.
- Broken authentication and session management – Authentication failures and fake user sessions can lead to attackers gaining access to user accounts which they can use to steal or misuse sensitive data.
- Insufficient logging and monitoring – If attackers manage to exploit a vulnerability in an application, it’s important to have the ability to track their activities so they can be quickly identified and remedied. However, many applications don’t have adequate logging mechanisms in place to monitor suspicious activity or log events that might indicate an attacker has compromised the system.
- Cross-site request forgery – This happens when a user is tricked into submitting a malicious form without knowing it. The goal of this type of attack is usually to hijack cookies and steal data from other websites that the user visits.
- Sensitive data exposure – When a vulnerability in an app provides access to sensitive data such as passwords, financial information, or social security numbers, a breach occurs.
- Broken access control – If access controls are not properly set up or maintained on applications, attackers may be able to bypass security measures and gain access to sensitive data or functionality.
Types Of Application Security Testing
Now that we have a better understanding of the types of threats that applications can face, let’s take a look at the different types of security testing that can be used to mitigate these risks. The two most common types are SAST and DAST:
Static Application Security Testing (SAST):
SAST is a type of software testing that examines an application’s source code to identify potential vulnerabilities. It can be used to perform penetration tests, identify coding errors and vulnerabilities, and recommend solutions.
SAST is usually performed during the early stages of development while the code is still being written. This allows developers to fix any potential issues before they become a bigger problem and cause more damage.
Dynamic Application Security Testing (DAST):
DAST is a type of software testing that analyzes an application’s behavior as it runs in its intended environment. It can be used to perform pentests, identify coding errors and vulnerabilities, and recommend solutions.
DAST is usually performed during the later stages of the software development lifecycle when the code is stable enough to run on its own. This allows testers to identify issues that may not be caught during static testing.
The importance of SAST and DAST are critical for enhancing mobile and web applications’ security. They can help identify vulnerabilities before they become a problem and cause damage to the business. It’s critical to apply both types of testing in order to obtain the most comprehensive picture of your application’s security.
SAST can be used during development while DAST should be performed during deployment of certain phases and after complete deployment so that issues can be identified as early as possible.
