What is Security Testing in QA & Why is it So Essential

What is Security Testing in QA? Types of Security Testing

According to the Security Testing methodology document, there are seven basic forms of security testing. The following are the explanations:

1. Vulnerability Scanning: This is done by scanning a system against known vulnerability signatures using automated tools.
2. Security Scanning: This entails discovering network and system flaws and then proposing remedies to mitigate the risks. This scanning may be done in two ways – manually and automatically.
3. Penetration Testing: This kind of testing replicates a hostile hacker's attack. This testing entails examining a specific system for possible vulnerabilities in the event of an external hacking attempt.
4. Risk Assessment: This kind of testing entails analyzing the security threats that have been identified in the company. There are three levels of risk: low, medium, and high. This testing suggests risk-reduction controls and procedures.
5. Security Auditing: This is an internal check for security issues in applications and operating systems. A line-by-line examination of code may also be used to conduct an audit.
6. Ethical Hacking: Hacking an organization's software systems is referred to as ethical hacking. Unlike criminal hackers who steal for personal benefit, the goal is to uncover system security problems.
7. Posture Assessment: Security scanning, ethical hacking, and risk assessments are combined in a posture assessment to reveal an organization's overall security posture.

Why Security Testing is Essential in QA?

• It Fits the QA Role: The entire team in the SDLC should be able to satisfy the demands by checking and testing the application vulnerabilities from a security standpoint. The QA team should continuously look for vulnerabilities in the network, system software, and client-side application or server-side application security.
• A High-Quality Application: A bug-free and high-quality software application is not only one that functions well but is also secure. A QA team that pays attention to detail and has an eye for security risks can help add an extra layer of protection against cyber threats. Many use cases of security testing encompass essential areas like password encryption, permissions, logins, session timeouts, and cookies to more advanced ways of bypassing existing controls.
• Cost-Effective: The cost of fixing a security flaw post-release is significantly higher than fixing it during the development phase. It is important to note that vulnerabilities are often discovered only after the product has been deployed. QA teams with expertise in application security testing can help organizations save time and money by identifying potential security risks early on in the SDLC.
• Compliance and Regulations: Many industries have strict regulations in place regarding data privacy and security. For example, the healthcare industry must comply with the Health Insurance Portability and Accountability Act (HIPAA) regulations, while the financial industry must comply with the Payment Card Industry Data Security Standard (PCI DSS). Failing to comply with these regulations can result in hefty fines, loss of customer trust and damage to reputation. Conducting security testing helps ensure that the application meets the required standards and regulations.
• Protecting Intellectual Property: In today's competitive market, protecting intellectual property is critical to business success. Security testing can help identify vulnerabilities that may lead to the theft of intellectual property, such as proprietary algorithms, customer data, or business plans. It is essential to have a QA team that is proficient in security testing to identify and mitigate these risks.
• Avoiding Downtime and Service Disruptions: Cyberattacks can cause downtime and service disruptions, which can have a significant impact on a business's revenue and reputation. By conducting security testing, the QA team can identify potential threats and vulnerabilities that may lead to service disruptions. This helps organizations prepare and take preventive measures before an attack occurs.
• Enhancing Customer Confidence: Customers trust organizations that can ensure the safety and security of their personal and financial information. By conducting security testing, the QA team can identify and mitigate security risks, thereby enhancing customer confidence in the application and the organization. This, in turn, can lead to increased customer loyalty, improved brand image, and increased revenue.
