At Impress Computers, we understand that managing your organization’s cybersecurity is more than just a series of isolated tasks—it’s an ongoing process that evolves with the ever-changing digital landscape. One of the critical aspects of this process is distinguishing between attack surface management (ASM) and exposure management, two complementary strategies essential for comprehensive cybersecurity.
Understanding Attack Surface Management (ASM) Attack surface management is the continuous process of discovering and identifying all assets that could be visible to an attacker on the internet. This includes pinpointing security gaps that could be exploited, as well as identifying areas where your defenses are robust enough to repel potential attacks. Essentially, if an asset is exposed online and could be targeted by an attacker, it falls under the realm of ASM.
The Evolution to Exposure Management While ASM focuses on the visible attack surface, exposure management goes a step further by encompassing all digital assets, user identities, and cloud account configurations. This process allows organizations to consistently evaluate the visibility, accessibility, and vulnerability of their digital assets, ensuring a more holistic approach to security.
The Continuous Journey of Managing Threats Continuous threat management is crucial because neither your business nor the threat landscape is static. New vulnerabilities emerge constantly, and attackers are always updating their techniques. Moreover, as businesses frequently update systems and deploy new services, the attack surface continuously evolves, potentially creating new security gaps.
Moving Beyond Traditional Vulnerability Management Traditional vulnerability management often focuses on issues identified through Common Vulnerabilities and Exposures (CVEs). However, at Impress Computers, we believe that any weakness in your attack surface is a vulnerability, regardless of whether it has an associated CVE. For example, an exposed SQL injection vulnerability or an open Windows Remote Desktop may not have CVEs but still pose significant risks.
Exposure management, therefore, broadens the scope to include misconfigurations and potential weaknesses that lack CVEs. This comprehensive approach ensures that all vulnerabilities, whether or not they are formally recognized, are managed effectively.
Prioritizing Vulnerabilities with Context Effective vulnerability management isn’t just about identifying issues; it’s about prioritizing them in a way that makes sense for your organization. Impress Computers emphasizes the importance of context when managing vulnerabilities. Understanding which assets are critical to your business, how vulnerabilities can be exploited in combination, and where attackers might enter your network are all crucial to making informed decisions.
This approach transforms vulnerability management from isolated tasks into a cohesive strategy, helping you determine not only if a vulnerability should be fixed but also when it should be addressed.
Why Exposure Management Matters Not every vulnerability needs to be fixed immediately. Without a strategic approach, your team might waste valuable time addressing low-impact issues instead of focusing on vulnerabilities that could compromise mission-critical systems. Exposure management helps you focus on what truly matters, allowing your team to make a meaningful impact on your organization’s security profile.
By understanding your environment, identifying key assets, and setting appropriate thresholds for action, you can significantly reduce the workload on your team and ensure that their efforts are directed towards securing the most critical aspects of your business.
The Need for Exposure Management: Real-World Examples Recent cybersecurity incidents highlight the importance of exposure management. For instance, the discovery of a backdoor in the xz-utils software, which could have allowed attackers to execute commands on compromised systems, underscores the risks associated with seemingly minor vulnerabilities. Similarly, the critical zero-day vulnerability in Palo Alto Networks’ PAN-OS software demonstrates how quickly a small security gap can become a significant threat.
With exposure management in place, organizations can quickly identify vulnerable assets and take swift action to mitigate risks, rather than reacting to threats after they have already caused damage.
Starting Your Journey with Impress Computers Embarking on an exposure management journey doesn’t have to be overwhelming. At Impress Computers, we recommend starting with practical steps:
- Leverage Existing Tools: Use the services you’re already utilizing. For example, if you’re working with Impress Computers, we can help you integrate vulnerability management and attack surface management into a comprehensive exposure management strategy.
- Define Your Scope: Focus on assets exposed to the internet first, as they are often the most vulnerable. Use tools to segment systems and assign responsibility for remediation.
- Discover and Prioritize Assets: Identify both known and unknown assets, determine which are critical to your business, and assess their risk levels.
- Act Decisively: Once vulnerabilities are identified, take appropriate action through remediation, mitigation, or risk acceptance. Impress Computers can help you manage and verify these efforts.
Bringing It All Together At the end of the day, cybersecurity is about focus. By minimizing distractions and enabling your team to concentrate on what truly matters, exposure management allows you to achieve the greatest impact with the least time invested.
With Impress Computers by your side, you can ensure that your digital landscape is secure, giving you the peace of mind to step away from your desk knowing your assets are protected. Exposure management isn’t just about managing vulnerabilities—it’s about managing your focus in the endless stream of cybersecurity threats.
