Attack surface management: continuous discovery and assessment

Attack Surface Management: Continuous Discovery and Assessment in an Age of Digital Threats

The digital world is a battleground. Every day, organizations face a barrage of cyber threats aimed at exploiting vulnerabilities. In this environment, attack surface management (ASM) is no longer a luxury – it’s a necessity.

Think of your organization’s attack surface as the sum of all its digital points of entry. This includes everything from servers and websites to employee laptops and mobile devices. Each point represents a potential target for attackers.

The First Amendment Connection: Protecting Your Digital Voice

The recent news about attacks on the First Amendment highlights the importance of protecting our digital voices. Just as freedom of speech is vital in the physical world, so too is the security of our online platforms and communications crucial in the digital age. A robust attack surface management strategy can be a key tool in this fight.

Imagine a non-profit organization dedicated to free speech. Their website, donation platform, and communication channels are all potential targets. A successful attack could silence their message, disrupt operations, and erode public trust. Effective ASM helps ensure their vital work continues unimpeded.

Continuous Discovery: Knowing Your Weaknesses

The first step in ASM is continuous discovery. This means constantly scanning your digital environment to identify all assets and potential vulnerabilities.

Automated Tools: Utilize automated tools to scan for exposed servers, outdated software, and misconfigured settings.
External Perspective: Employ external security researchers or ethical hackers to simulate real-world attacks and uncover hidden weaknesses.
Dark Web Monitoring: Monitor dark web forums and marketplaces for mentions of your organization or leaked credentials.

Continuous Assessment: Prioritizing and Mitigating Risks

Once you understand your attack surface, you need to continuously assess and prioritize risks. Not all vulnerabilities are created equal.

Risk Scoring: Assign risk scores to vulnerabilities based on their potential impact and likelihood of exploitation.
Threat Intelligence: Leverage threat intelligence feeds to understand which vulnerabilities are actively being exploited by attackers.
Prioritization: Focus on patching or mitigating the highest-risk vulnerabilities first.

Real-World Example: The Equifax Breach

The 2017 Equifax breach, which exposed the personal data of over 147 million people, is a stark reminder of the importance of ASM. The breach was caused by a known vulnerability in Apache Struts, a popular web application framework. Equifax had two months to patch the vulnerability but failed to do so.

This example highlights the critical need for both continuous discovery (identifying the vulnerability) and continuous assessment (prioritizing and patching it).

Benefits of Continuous ASM

Implementing a continuous ASM program offers numerous benefits:

Reduced Risk: Proactively identifying and mitigating vulnerabilities significantly reduces the risk of a successful attack.
Improved Security Posture: Continuously assessing and improving your security posture makes your organization a less attractive target for attackers.
Enhanced Compliance: ASM helps organizations meet regulatory requirements related to data security and privacy.
Cost Savings: Preventing a breach is always more cost-effective than dealing with the aftermath.

Conclusion

In today’s digital landscape, attack surface management is not optional. It’s an essential component of any comprehensive cybersecurity strategy. By embracing continuous discovery and assessment, organizations can stay ahead of emerging threats and protect their valuable assets, including their digital voice.
