The modern cybersecurity landscape is one characterized by near-constant evolution. With new technological development, there inevitably come new threats, meaning we must find new ways to defend ourselves against potential attacks. Now, with AI becoming the dominant force driving the digital ecosystem, it seems alternatives to traditional security testing are in order, and continuous security validation (CSV) may just be exactly what we need. But just what are the limitations of existing testing methods, and how can CSV better solve the challenges of modern cybersecurity?
The Emerging Need for Proactive Security
Penetration testing has historically been a core aspect of how organizations seek out vulnerabilities, upscale their defense, and ultimately protect against the threats that malicious actors pose, and for the longest time, it has been largely effective. However, the threat landscape has changed drastically in recent times, altering perspectives around pentesting.
It’s an axiom of cybersecurity that threat actors are always working to develop more advanced attack methods, and the role of security experts has always been to understand and counteract those methods as they are developed. In this aspect, pentesting has been largely effective over the years, but with the advent of AI, threat actors now have the capability to develop more sophisticated payloads. Malware and ransomware are becoming more complex, fast-acting, and difficult to detect, and so advanced persistent threats (APTs) are a growing threat to enterprises. Likewise, attackers are now empowered to exploit vulnerabilities in third-party software more quickly, with zero-day exploits becoming increasingly common.
These developments have culminated in a situation in which vigilance and proactivity are now critical to effective cyber defense, and it seems as though traditional pentesting may not be fit for purpose as it once was.
Limitations in Traditional Testing
For the time being, third-party external pentesting remains useful, providing some valuable insight into vulnerabilities that in-house teams might be ill-equipped to identify. However, the testing method is beginning to show signs of age in the fast-paced and increasingly AI-driven realm of cybersecurity.
One key limitation is the periodic nature of the assessments. Traditional pentesting is typically carried out at scheduled intervals, with client companies soliciting the services of testing firms several times per year. This method provides a snapshot of an organization’s network to show what vulnerabilities exist at that point in time, which is useful, but the organization is effectively left in the dark as to what goes on between tests. With threats evolving as quickly as they do now, this can be problematic.
Another downside to traditional pentesting is the limited scope of the assessments. Pentesters are usually brought in to carry out focused tests on specific applications, systems, or networks to identify their vulnerabilities. Again, while this is useful, the issue is what the tests fail to do. Given the wide range of vectors that attackers are now able to exploit, organizations simply cannot achieve the coverage they require by relying solely on tests with such a narrow purview.
Lastly, there is also the issue of efficiency to consider. The reality is that traditional penetration testing can be expensive and time-consuming, often necessitating some degree of downtime. Additionally, depending on the scale of testing, reports can be slow to arrive relative to the speed at which threat actors now operate, meaning some of the vulnerabilities identified during tests may have already been exploited by the time the client has received the report. For organizations to keep pace with evolving threats and maintain the kind of visibility they require these days, they need validation to be fast, scalable, and cost-efficient.
These limitations point to a need for evolution in cybersecurity. While traditional pentesting will still have a role to play in more focused processes, organizations need more proactive and adaptive security solutions. To combat modern cyber threats, they need to fight fire with fire by leveraging AI and automation in cyber defense, and this is where continuous security validation comes into play.
The Role of Continuous Security Validation
Continuous security validation is a process whereby an organization assesses its security controls on an ongoing basis. It is done through the implementation of automated security validation (ASV) software, which simulates real-world attack scenarios to seek out potential vulnerabilities in applications, systems, and networks. This method offers some distinct advantages when compared to traditional testing.
Firstly, by its very nature, continuous validation facilitates enhanced detection and response capabilities. Through the implementation of real-time monitoring, this approach allows organizations to maintain constant visibility over their attack surfaces. This means that they can more quickly identify indicators or compromise and respond to potential threats to minimize cyber exposure.
Secondly, since automated security validation tools use regularly updated threat libraries to simulate attacks, they can test security controls in a wide variety of scenarios. This provides more comprehensive coverage so that organizations can be more resilient to evolving threats.
Finally, by leveraging automation, continuous security validation enables organizations to carry out routine schedule testing at scale without the need for manual intervention. In doing so, it improves protection while reducing costs and downtime and allowing security teams to focus their efforts on tasks that require their direct attention.
By empowering organizations to validate security controls in an efficient, cost-effective, and scalable way, continuous security validation can cover the gaps that traditional penetration testing leaves. This facilitates more proactive, front-font defense strategies that are better suited to the challenges of today’s threat landscape.
Achieve Digital Resilience with CSVÂ Â
Cyber threats are growing more sophisticated all the time, whether we like it or not, and our organizations need to adapt if they are to stay secure going forward. While traditional testing methods still have utility, it’s becoming increasingly clear that they cannot keep pace with the evolution of modern cyber threats, but continuous security validation can offer the solution. By embracing AI and automation in security validation, we can achieve real-time visibility and rapid response capabilities at scale, and empower our organizations to become more proactive and resilient in the fight against evolving cyber threats.
