Current developments in AI systems show that vulnerabilities are found more quickly, suitable exploits are developed more quickly, and attacks are increasingly implemented automatically. This significantly reduces the time between discovery and exploitation. What used to take weeks or months often happens within a very short time today.
For many organizations, this means that existing vulnerability management processes are no longer sufficient to keep up with this dynamic. Assessment, prioritization, and remediation often still take place in periods of time that no longer correspond to the current threat situation.
At the same time, the development will continue to intensify. Organizations must expect to be confronted with a significantly higher number of critical vulnerabilities in a short period of time.
It is therefore no longer just a matter of recognizing vulnerabilities but of how quickly and in a structured manner they are reacted to.
Where Existing Processes Reach Their Limits
The challenge is particularly evident in operational implementation: existing processes are not designed for the required speed and volume. Today, numerous vulnerabilities need to be assessed, prioritized, and remediated simultaneously.
This dynamic is further reinforced by the use of AI on the attacker side. Dependencies in the software supply chain also increase complexity: a single vulnerability can affect many systems at the same time and require quick action. In addition, 0-day vulnerabilities increase the pressure, as they require additional measures in detection and processing.
In practice, manual sub-steps, incomplete data, and rigid processes are the main obstacles. Prioritization and follow-up are not risk-based; decisions take too long, measures take effect late, and patch cycles are too long. This is exactly where the gap between increasing attack dynamics and operational responsiveness in defense arises.
Organizations must therefore adapt their processes to evolving conditions so they can prioritize quickly and remain operational even under high loads.
What Needs to Change in Vulnerability Management Now
Markus Ritter, Managing Consultant IT Security at usd, accompanies organizations from various industries in setting up and further developing their vulnerability management in interaction with all its interfaces. His project experience shows that the basic tasks remain the same under the current conditions. What is important now is how consistently and how quickly they are implemented under the changed conditions.
This results in three central objectives for action:
Consistently reduce the window of exposure
The decisive factor is not the number of vulnerabilities discovered, but how long they remain exploitable. It is crucial to quickly identify the vulnerabilities that can actually have serious impacts in the organization’s specific context and to limit them effectively. Even when no patch is yet available.
Deliberately keep the attack surface small
Only those who know their own assets, interfaces, dependencies, and their protection requirements can prioritize risks sensibly. The focus is on particularly exposed assets: their exposure and connections should be regularly reviewed and limited to what is necessary. In addition, hardening measures should be consistently implemented at all levels.
Limit the impact of attacks
Not all vulnerabilities can be closed in the short term; this is especially true for 0-day vulnerabilities. This makes it all the more important to limit impacts in a targeted manner, for example, through hardening, segmentation, monitoring for early detection of attacks, and clearly defined response processes.
What Needs to Be Implemented Now
The goal is to be able to make decisions quickly, to address the vulnerabilities that matter most earlier, and to measurably reduce the actual attack surface.
These requirements result in concrete fields of action for practice:
- Consistently align prioritization with risk: Context is decisive: asset criticality, exposure, and actual exploitability, not just CVSS values. Truly significant vulnerabilities must be addressed without delay.
- Bring data together and make it usable: Asset data, vulnerability information, and operational knowledge need to be integrated in real-time so that decisions can be made quickly.
- Secure and monitor exposed systems in a targeted manner: External attack surfaces must be evaluated transparently and continuously. Changes must be incorporated directly into the prioritization.
- Proactively detect vulnerabilities: Vulnerability scans and structured pentest programs identify vulnerabilities at an early stage. Scenario pentests and red teaming check one's own defense capability.
- Remaining able to act even without a patch: For 0-day scenarios, alternatives must take effect: hardening at all levels, monitoring to detect attacks, incident response, and mitigating measures.
- Strengthen the Integration of Vulnerability Management: Vulnerability management must interact with operations, monitoring, and incident response in order to be effective. Maintaining short patch cycles in operations is essential.
- Reduce manual process steps: Automation in all interlocking building blocks is a prerequisite for keeping up with the pace. AI can support these processes, but the final assessment should remain in the hands of human experts.
Markus Ritter assesses the situation as follows: "The basic measures are known in most organizations. Today, it is crucial to be able to quickly assess which vulnerabilities are actually relevant in the organization’s specific context and to react to them consistently. Above all, this requires transparency about assets and dependencies as well as clearly defined priorities."
