You are being targeted, like any organization with networked IT, and there is no way to prevent that entirely. What matters is how fast a vulnerability gets closed before it becomes an actively exploited attack vector. That is a race against time, with clear phases and measurable metrics.

Key Takeaways
An attack vector is the concrete path an attacker uses to actually exploit a vulnerability. From creation to closure, every vulnerability moves through several phases, and a clock is ticking in each one. According to Mandiant's M-Trends 2026, the mean time to exploit has already dropped to -7 days, meaning attacks often begin before a patch even exists.
Key benefits of continuous vulnerability management include:
  • Faster detection of new vulnerabilities in your own environment
  • Prioritization by real risk instead of CVSS alone
  • Measurable time to detect and time to remediate

What Is an Attack Vector?

An attack vector is the concrete path an attacker uses to actually exploit a vulnerability in a system, application or network, for example an unpatched software flaw, a misconfiguration or stolen credentials. The term is often confused with attack surface: the attack surface covers every potential entry point into an IT environment, while the attack vector is the specific path an attacker actually takes.

This page looks at a particular angle on attack vectors: their timeline. Every vulnerability that could become an attack vector moves through several phases from creation to closure. How fast these phases pass determines whether a flaw gets exploited or closed in time. For a deeper technical look at the CVE process itself, see our page Vulnerability Timeline – From CVE to Enterprise Feed.

The Race: Time to Exploit vs. Time to Remediate

The moment a vulnerability becomes public, a three-leg race begins. The first leg sits entirely with vendors like Greenbone, the other two happen inside your own environment:

Build the Test

A vulnerability test needs to exist that reliably reveals the flaw. This leg sits entirely with vendors like Greenbone.

Detect the Vulnerability

The test needs to run in your own environment to check whether the vulnerability is actually present.

Close the Vulnerability

Once detected, the flaw needs to be prioritized and fixed, through a patch, a configuration change or a compensating control.

Attackers run a strikingly similar three-step process, except that testing and closing are replaced by building and running an exploit. Whoever completes their own legs faster than the other side wins the race:

Attack Vectors in Numbers

Current data shows just how far this race has tilted in attackers’ favor:

Five Phases of an Attack Vector

Every attack vector moves through the same five phases from creation to closure. The overview below shows what happens in each phase and how Greenbone helps shorten it:

Phase What Happens Greenbone's Role
Creation A vulnerability enters a product unnoticed, for example through a coding error or an insecure default configuration. At this point, nobody knows about it, including attackers. Greenbone follows security-focused processes in its own product development and advises customers to do the same in their own software development and third-party module integration.
Becomes Known Someone discovers the vulnerability. In most cases it is reported responsibly, but occasionally an attacker keeps the discovery secret to exploit or sell it. Greenbone monitors the channels where newly discovered vulnerabilities are discussed and starts building a test early, often before an official CVE entry exists.
Detectable A method exists to reliably prove the vulnerability's presence in an IT environment. Greenbone publishes one or more vulnerability tests in the OPENVAS feed and keeps updating them as new information becomes available.
Detected in Your Environment Your own scan shows the vulnerability is present in your environment. This is where prioritization and action speed matter most, often slowed by limited resources or a pending vendor patch. OPENVAS delivers CVSS- and risk-based prioritization directly in the scan report and offers managed services to support remediation.
Closed The vulnerability is fixed or effectively mitigated. The attack vector no longer exists in your environment. Greenbone's goal is to keep the "becomes known," "detectable" and "detected" phases as short as possible, so you reach this point faster than attackers reach exploitation.

Why the Gap Keeps Widening

Several trends currently give attackers the edge in this race:

AI-Generated Exploits

Generative AI can turn a vulnerability description into a working exploit in a short amount of time, significantly lowering the barrier to entry for attackers.

A Growing Number of CVEs

With 48,185 new CVEs, 2025 saw more vulnerabilities published than ever before. Without clear prioritization, full coverage becomes practically impossible.

Edge Devices and VPNs in the Crosshairs

VPN and edge device vulnerabilities accounted for a far larger share of breaches in 2024 than the year before, according to Verizon’s 2025 DBIR, often with very long real-world remediation times.

How Greenbone Shortens Every Phase

OPENVAS was built to shorten exactly the phases that are in your own hands: detection and closure.

Automated vulnerability management for mid-size to large organizations, with continuous scanning, CVSS-based prioritization and a daily updated vulnerability feed.
Vulnerability management for small businesses and single sites, ready to go in minutes with a free 14-day trial.

Checklist: Close Attack Vectors Faster

A first, concrete plan to win the race against attackers:

  • Establish continuous vulnerability management instead of one-off scans
  • Keep the OPENVAS feed updated daily
  • Prioritize vulnerabilities by CVSS and actual exploitability
  • Shorten patch windows for critical systems and set firm deadlines
  • Include edge devices and VPNs in your scan scope
  • Continuously measure time to detect and time to remediate
  • Define emergency processes for zero-day vulnerabilities

Frequently Asked Questions About Attack Vectors

An attack vector is the concrete path an attacker uses to exploit a vulnerability, for example an unpatched software flaw, a misconfiguration or stolen credentials.

No. A vulnerability is the technical flaw itself, while an attack vector is the path through which that flaw is actually exploited. Not every vulnerability necessarily becomes an active attack vector.

Time to Exploit describes the interval between a vulnerability’s disclosure and its first observed exploitation. According to Mandiant’s M-Trends 2026, this now averages -7 days, meaning attackers are often already active before a patch is available.

Time to Remediate is the time an organization needs to fix a known vulnerability, from detection in its own scan to effective closure.

Greenbone starts building a test as soon as a vulnerability becomes known, often before an official CVE entry exists. See our page Vulnerability Timeline for details.

No defense system is one hundred percent secure, and new vulnerabilities are disclosed every day. The goal is therefore not absolute security, but the shortest possible time between disclosure and closure.

Only recurring scans reliably show when a new vulnerability appears in your environment. One-off or infrequent checks often leave attack vectors undetected for weeks.
