Discover strategies to protect your software against threats with advanced security testing.
We live in a time of increasing security threats and attacks. Security testing in software testing is more important than ever. It serves as a robust protective shield, scanning software products for potential weaknesses to prevent potential attacks.
Why security testing in software testing is essential
Security testing is essential to safeguard software integrity and protect both companies and end users.
The rise of cyber threats
Over the past decade, the world has seen an alarming increase in cyber threats, with an exponentially greater number of data breaches. Experts expect that more than cybercriminals will steal more than 33 billion records in 2023 alone, a 175% increase in the last 5 years alone. In 2022, an additional 422 million individuals felt the effects of data compromise, such as data breaches, leaks, and exposure.
Commercial implications
Companies that are victims of data breaches suffer immense financial and reputational consequences. The global average cost of a data breach in 2023 is $4.45 million , an increase of more than 15% over the last 3 years. The reputational cost associated with the loss and exposure of sensitive data is something few companies can overcome, with 46% of organizations suffering damage – financial, reputational and otherwise – from a data breach.
User trust and brand image
Security threats and data breaches severely tarnish a brand's image and undermine the trust of its customers or users. After feeling betrayed by a company, customers often choose to use or work with competitors, causing even more damage to the brand. Data breaches and security threats cause a ripple effect that creates a long-term crisis of trust for users and harms businesses.
Types of security testing
To successfully navigate the complicated cyber threat landscape, companies must utilize a variety of different security tools and tests for their software. From vulnerability scanning to dynamic testing to penetration testing, these practices help keep bad actors at bay with proactive measures.
Vulnerability scanning
Vulnerability scanning is a type of security scanning that systematically analyzes, identifies, and reports potential areas of weakness or security flaws in software systems. This is a critical type of testing to prevent cyberattacks by ensuring that robust defense mechanisms have the ability to protect the software. Tools like Nessus and Nexpose offer companies comprehensive insights into the security vulnerabilities of their systems.
Penetration Testing
Penetration testing involves simulating a cyberattack against a system to discover exploitable vulnerabilities and potential security issues before real hackers have the opportunity to do so. This involves three types of methodologies that, when combined, offer comprehensive insights into the system and ensure a stronger security defense from multiple angles.
- Black Box: The tester has no prior knowledge of the system.
- White Box: The tester has extensive knowledge of the system.
- Gray Box: The tester has a limited amount of system information.
Security audit
Software security auditing measures an entire system to assess the extent to which it complies with a set of established criteria. The auditor goes through a series of steps, including risk assessment, testing for system vulnerabilities, review of controls, and policy compliance assessments to obtain the most holistic view of all of a system's security defenses. Security auditors use tools like Nmap and Wireshark.
Risk assessments
Like insurance processes, cybersecurity risk assessment is a structured process of identifying and classifying potential threats to the system. This assessment examines many elements, including the potential impact of threats, the likelihood of an occurrence, and potential vulnerabilities. Professionals typically employ tools like Microsoft Threat Modeling to help prioritize their defense strategies against the most substantial risks.
Ethical Hacking
Using their skills for good rather than evil, ethical hackers simulate cyberattacks to expose system vulnerabilities before real cybercriminals do. This type of security analysis complements more traditional testing measures, using real-world scenario analysis for a more comprehensive security strategy.
Security Testing Tools
There are many tools to help companies navigate the intricate security testing process. Tools like Burp Suite and OWASP ZAP help facilitate early vulnerability detection while automating repetitive tasks to optimize security testing efficiency.
