Test-Break-Fix-Repeat; Why Security Testing is your Cyber Stress Test

Weakness = Weaponized

Most attacks, in the real world, hardly start off with a zero-day exploit; it’s often a well-documented vulnerability, some kind of misconfiguration, or an exposed, perhaps overlooked security gap. Security testing, moves that risk window in your favor.

A Vulnerability assessment can identify known issues such as outdated software, missing patches, open ports, weak configurations and even default credentials which may cause a vulnerability.

A literature review makes the case that penetration testing is critical not only for detection, but for prioritizing remediation, to help organizations focus their efforts on the gaps with the highest risk potential (Alhamed & Rahman, 2023).

Routine testing helps ensure that you reduce the window during which vulnerabilities can exist undiscovered – and be weaponized by attackers.

Beyond the Scan: The Human Factor

Technical defenses find technical vulnerabilities; however, attackers jump over them by targeting human behavior, too often. People, process and culture must be part of a robust testing regime, as well.

A new interdisciplinary survey finds that people, human behavior, decision-making, organizational culture and security awareness form “the cornerstone of cyber resilience.” It further argues that defenses “must go beyond piling technical safeguards on top of one another” by including human-centered approaches (Khadka & Ullah, 2025).
A related review found that human error, fatigue, overconfidence and inadequate training are among the most common root causes in cybersecurity incidents, and that the “human factor” is often the most critical vulnerability when overlooked (Khadka & Ullah, 2025).
Research has found that the security leadership in organizations, needs to manage communication, security awareness training and the social work environment to mitigate unintentional human risks (Triplett, 2022).
In some cases attackers use social engineering techniques as an initial step during an intrusion. Phishing, pretexting or impersonation can provide initial access or credential disclosure to allow technical exploits to follow. Pen tests and red teams often try such techniques to assess whether people and processes can withstand them (Evans, Maglaras, He, & Janicke, 2016).

Testing programs should simulate realistic attacker behavior that targets humans, processes, and technology together, not just system vulnerability.

Continuous Validation in a Dynamic Environment

Continuous Validation. In dynamic, fast-paced IT environments (cloud-native, APIs, microservices, frequent deployments), traditional “audit once per year” cadence can be too slow. Controls regressions, misconfigurations, or new exposures could happen daily, even multiple times a day.

Continuous security validation” (CSV) has been defined as “embedding testing and assessment into the operational infrastructure and automating adversary-style probing against live systems, in order to confirm the controls are effective and deployed systems are not exposed to known or unknown threats (Hubbard, 2020).
One whitepaper on validating cloud-native controls similarly observes that automated, continuous validation can help overcome some of the constraints of manual testing: “scaling in a more reliable way and with much more frequency, and tests if defenses can indeed detect and block simulated malicious activity” (Hubbard.J, 2020).
In an exploration of modern pentesting, investigators have noted that key challenges with existing solutions include the cost, shortage of qualified testers, and requirement for automation, all of which point to benefits to adopting continuous or hybrid validation models (Bertoglio, Gil, Acosta, Godoy, Lunardi, & Zorzo, 2023).

Validating defenses continuously helps close the gap between when a vulnerability is introduced and when it’s detected, limiting windows of opportunity for attackers.

In cybersecurity, assumptions are fragile. You can’t defend what you haven’t tested. Security testing is the process of turning assumptions into testable and executable statements of fact. It enables organisations to:

Find weaknesses before attackers do,
Account for human and process vectors, and
Validate controls continuously in a fast-moving environment. The cycle of “test, break, fix, repeat” is more than methodology; it is the engine of resilience in an adversarial world.
