Patch Window Within Three Days: CISA’s New Directive

A patch window of three days is definitely an indicator of an accelerated process of vulnerability management. CISA’s directive recognizes the harsh truth that after a vulnerability goes into public domain and is actively exploited, defenders could be left with only a limited time before an attack against the vulnerability takes place. There will be no more room for slow responses in this case.
It doesn’t necessarily mean that all patches should be applied right away in any environment. However, what it means is that certain vulnerabilities are extremely critical and cannot be waited for anymore.

The Reason Why The Timeframe Is So Short
Once an important security flaw is made public, attackers start scanning rapidly. It is now easier for them to detect vulnerable systems using automation, and exploitation usually starts soon after the disclosure. The three-day period acknowledges the fact that delay can raise the risk of compromise.
It means that companies need to improve on their asset management, prioritization, and deployment capabilities. You cannot patch your vulnerable systems unless you first know what they are. You cannot limit exposure until you first identify your critical assets.

Change Is Needed
Organizations should have pre-defined patch processes, ownership, and rollbacks. In addition, there must be a distinction between patching cycles and exploiting events. Time will play a critical role in determining whether the organization will be resilient or breached when dealing with Internet exposed assets, identity platforms, and critical infrastructures.

The Bigger Lesson
It is evident from CISA’s three-day directive that vulnerability management has become a race. Organizations that can act fast will always be better than those with longer maintenance windows.
