Supply chain attacks and Zero-days

The year 2021 has seen several high profiled vulnerabilities being actively exploited in big
and popular software, including Microsoft Exchange and Solar Winds Orion.
Experience shows that in some cases it is too late to patch even after a few days.
Many organizations work with the guideline of patching within 30 days, if the vendor states the
update is of important nature. This is an attempt to verify that the patch does not cause any
adverse effects. The need for a vigilant Vulnerability Management process that continuously triage
published vulnerabilities is becoming clear.

Some of the issues published lately is Supply chain attacks, where an attacker manipulates
products or product delivery mechanisms prior to receipt by a final consumer or exploiting
previously unknown vulnerabilities (so called Zero Days). Defending against these attacks is in
some cases not possible, or at least demands such a high level of security that it often is difficult
to stay productive and profitable. Seemingly in some cases it seems like the best an organization
can do is to not be the weakest link and the easiest target.

It is important to prepare for an attack and have a plan for incident response. Perform exercises.
Deploy a security framework in order to engage in continuous improvement of the security
posture.
