Over the past decade, the world saw an alarming increase in cyber threats with exponentially increased numbers of data breaches. Experts expect that more than cybercriminals will steal over 33 billion records in 2023 alone, an increase of 175% over just the last 5 years. In 2022, over 422 million individuals felt the effects of data compromises like data breaches, leakage, and exposure.
Business Implications
The victim companies 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 over 15% over the last 3 years. The reputational cost associated with the loss and exposure of sensitive data is one that few companies have the ability to 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 erode their customers or users’ trust. After feeling betrayed by a company, customers frequently choose to use or work with competitors, thus causing even more damage to the brand. Data breaches and security threats cause a ripple effect that creates a long-term crisis of confidence for users and damage to companies.
Types of Security Tests
To successfully navigate the complicated landscape of cyber threats, 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 malicious criminals 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 within software systems. This is a critical type of test to thwart cyberattacks by ensuring that robust defense mechanisms have the ability to guard 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 uncover 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 more fortified security defense from multiple angles.
- Black Box: The tester has no prior system knowledge.
- White Box: The tester has extensive knowledge of the system.
- Grey Box: The testier has a limited amount of system information.
Security Auditing
Software security auditing measures a full system to assess how well it conforms to an established criteria set. The auditor goes through a series of steps including risk assessment, testing system vulnerabilities, a review of controls, and policy compliance evaluations to perform the most holistic view of a system’s entire security defenses. Security auditors utilize tools like Nmap and Wireshark.
Risk Assessments
Much like the processes in insurance, risk assessment in cybersecurity is a structured process of identifying and ranking potential system threats. This assessment examines many elements, including the possible impact of threats, the likelihood of an occurrence, and the potential vulnerabilities. Professionals typically employ tools like Microsoft’s Threat Modeling to help prioritize their defense strategies against the most substantial risks.
Ethical Hacking
Using their skills for good and not evil, ethical hackers simulate cyberattacks to expose system vulnerabilities before the real cyber criminals do. This type of security analysis complements more traditional testing measures by using real-world scenario analysis for a more comprehensive security strategy.
Security Testing Tools
There are many tools to help companies navigate the intricate process of security testing. Tools like Burp Suite and OWASP ZAP help facilitate the early detection of vulnerabilities while automating repetitive tasks to optimize the efficiency of security testing.
