In a complex data-driven world, many security vulnerabilities and attacks can jeopardize an organization’s sensitive data. Perhaps the most difficult, however, are zero-day attacks.
Malicious attackers have gotten increasingly adept at identifying vulnerabilities and launching attacks to exploit these weak points in IT systems.
A zero-day attack is a cyberattack in which an organization or developer only learns of a flaw as it’s being exploited in that organization’s IT systems—which means that IT teams have “zero days” to fix the flaw.
According to some data, a surge in verified zero-day exploits in 2021 alone accounted for 40% of zero-day attacks undertaken in the past decade.
Zero-day attacks are a key theme at Black Hat 2022, a security conference taking place August 6-11 in Las Vegas. The centrality of zero-day attacks suggests that organizations need a better strategy to fend off these attacks. But they also need a better strategy to address these attacks if they have IT systems and live applications that are already compromised.
Cyberattacks such as the Log4Shell vulnerability, which emerged in late 2021, demonstrated the importance of having a runtime application vulnerability strategy. Advanced observability tools can enable organizations to identify and address dangerous zero-day vulnerabilities, such as Log4Shell. Such tools can prevent bad actors from injecting malicious code into applications that are accessible to the outside world. Further, by automating DevSecOps release validation through quality gates, organizations can ensure their releases are secure by default.
In this guide, we explore runtime application security strategies and how observability and application security can converge to protect organizations from the threats zero-day attacks pose.
DevSecOps: Integrating security into DevOps
Traditional approaches to application security struggle to keep up with the complexity presented by cloud-native environments and rapid software release cycles. As organizations hasten software development cycles to remain competitive, security vulnerabilities can make their way into live applications, because developers simply don’t have time to find and fix them. To address this, organizations are integrating DevOps and security, or “DevSecOps,” to detect and respond to software flaws in production faster and with more efficiency.
DevSecOps ensures that teams can address security concerns early in the software development lifecycle as well as in production. This approach helps organizations strengthen their application security, so they can better protect users and the business from cyberattacks, including zero-day attacks and data breaches.

Runtime vulnerability management: Staying ahead of zero-day attacks
Flexibility and agility are two major reasons why organizations are increasingly adopting cloud-native and open source technologies. Hybrid and multicloud environments are crucial for organizations looking to scale; however, they breed complexity that many traditional security solutions cannot adequately manage.
Moreover, with increased agility, organizations are now releasing new code faster than ever before. To facilitate software development in these faster release cycles, teams are turning to open source code libraries. Though convenient, third-party libraries can contain vulnerabilities that have the potential to compromise applications and sensitive data. Consider, for example, the recent Log4Shell and Spring4Shell vulnerabilities, which led to zero-day attacks.
A traditional, layered security posture is no longer enough. According to recent data, identifying and patching a vulnerability can take almost 7 months. How can organizations stay ahead of runtime vulnerabilities before they threaten sensitive information?

Zero-day attacks: Facing the unexpected head on
With organizations adopting remote work policies and investing in their online presence, cyber attackers are taking advantage of the recent shift towards digital, wreaking havoc on organizations, sensitive data, and software supply chains.
By definition, zero-day attacks take organizations by surprise. “Zero day” means bad actors discover and exploit security vulnerabilities before experts learn about them. As a result, teams have “0 days” to remediate such issues and are always at risk. While IT teams can be diligent at identifying vulnerabilities, these weaknesses are difficult to detect. Also, attackers can almost always find a loophole using strategies like phishing scams, watering hole attacks, business email compromise attacks, malicious sites, unauthorized access, and more.
