The Importance of Security Testing in Today’s Digital Age

As companies grow online, they face new dangers. Malicious individuals will stop at nothing to accomplish their objectives, be it financial gain, power, or influence. 

It’s crucial for businesses to prioritize cybersecurity and undertake measures like security testing to safeguard their critical digital assets from cybercriminals.

For example, in 2023, there were nearly 6 billion unauthorized data access incidents. Notably, Indian Council of Medical Research (ICMR) experienced the most significant breach of the year, compromising nearly 815 million records.

This shows that treating cybersecurity as less important won’t work anymore. It highlights how important security testing is to keep information safe. 

Now, let’s talk about what is security testing, and why almost every organization needs it.

Understanding Security Testing

Security testing checks whether the software can withstand cyberattacks and how it reacts to harmful or unexpected inputs. It shows that systems and information are safe and reliable and don’t accept illegal inputs. 

In cybersecurity, security testing is vital for checking and fixing security weaknesses in an application. It makes sure the application is protected from cyberattacks, unauthorized access, and data breaches.

This type of testing is called non-functional testing. Unlike functional testing, which checks if the program’s features work correctly (what the software does), non-functional testing examines if the application is constructed and set up correctly (how it operates).

Objectives of Security Testing

• Recognize Assets: These are the important things that need safeguarding, like applications and business infrastructure.
• Identify Weaknesses: These are the actions that can harm something valuable or flaws in one or more valuable things that attackers can take advantage of.
• Assess Risk: Security testing evaluates the chance that specific threats or weaknesses might harm the organization. This is done by measuring how serious a vulnerability or threat is and how likely it is to be exploited, along with the potential consequences.
• Address Issues: Security testing goes beyond just identifying problems with assets. It provides practical guidance on fixing discovered weaknesses and can confirm that they’ve been successfully resolved.

Essentials of Security Testing      

Security testing makes sure that an organization’s systems, applications, and data follow these important security rules:

• Confidentiality: This means controlling who can access important information stored in a system.
• Authentication: This is the process of safeguarding important systems or data by confirming the identity of the person trying to access them.
• Availability: This makes sure that important systems or data are ready and accessible to users whenever they’re required.
• Integrity: This involves making sure that data remains reliable, accurate, and trustworthy from start to finish and can’t be changed by people who aren’t authorized.
• Authorization: This guarantees that only people with the right roles or permissions can access important systems or data.
• Non-repudiation: This guarantees that data sent or received cannot be denied later on. It’s ensured by using authentication details and a verifiable time stamp.

Security testing is crucial for strengthening digital systems against cyber threats. By following security principles and goals, organizations can improve their cybersecurity position and protect their assets efficiently. 

Continuous assessment and enhancement of security measures are essential for staying ahead in the ever-changing cyber threats ecosystem.

1. Security Audits

Security audits involve comprehensive examinations of systems or processes to ensure they meet particular security criteria. For example, companies that process credit card transactions must conduct regular security testing to safeguard customer data, as enforced by the Payment Card Industry Data Security Standard (PCI DSS). These infrastructure security audits are essential for following industry rules. Failure to comply could result in penalties or even suspension of operations for the business.

2. Penetration Testing

What is penetration testing, also known as “pentesting,” is a systematic procedure where security experts intentionally seek and exploit vulnerabilities in an application. They assess the strength of the application’s defenses and simulate real-world attacks to determine potential outcomes if attackers were to breach them.

This method gives businesses a comprehensive insight into their security vulnerabilities, enabling them to make informed decisions about risk reduction and budget management. Security testing companies provide detailed pentest reports to businesses, outlining any vulnerabilities found in the app and recommending solutions.

3. Vulnerability Assessment

Vulnerability assessment uses automated tools to scan applications for known security problems. Some commonly used tools include Burp Suite, Mob SF, Nikto, Owasp Zap, APK tool, and Frida. Businesses can ensure that any vulnerabilities found are addressed promptly by regularly scheduling and performing these assessments. To effectively scan for the latest security flaws, it’s important to use an updated vulnerability database. Vulnerability scanners assess web applications externally to detect issues like cross-site scripting, SQL injections, command injections, insecure server configurations, and more.

4. Source Code Review

Source code review is an essential aspect of creating secure software, making it a vital type of security testing. Its goal is to uncover and address security weaknesses in an application’s source code. This proactive method ensures that security is a top priority in the software’s design, minimizing the risk of security breaches and data leaks. In a source code review, a skilled security analyst or developer meticulously examines the code, line by line, to pinpoint any security flaws, coding errors, or vulnerabilities that attackers might exploit.

5. SAST

Static Application Security Testing (SAST), also known as static analysis, is a method for testing software security through source code audit. This testing approach combines automated and manual methods to find vulnerabilities. It’s useful because it can detect problems without needing to run the software in a live environment. Engineers can carefully review the software source code audit and systematically address any security issues they find. SAST tools can delve deep into the code, uncovering vulnerabilities that might be missed by manual inspection.
