Find and Fix Docker Doomsday with BMC
That quote is true today just like it was in the 1700’s, and
while he was actually talking about fire safety (some believe he was referring
to staying healthy – not true), Mr. Franklin could just as easily have been
talking about protecting against security vulnerabilities, including a new and
very dangerous one, Docker Doomsday.
What is Docker Doomsday?
The Docker Doomsday vulnerability affects almost any
organization using Docker and containers. Here’s a quick look at what it does.
First, an attacker infects a container with a malicious program. The malicious
code exploits a flaw in runc, which is the container runtime utility for Docker
and Kubernetes.
Next, the malicious code breaks out and infects the entire
container host, and spreads to potentially thousands of other containers
running on that host. This is a Doomsday scenario because the attack can
ultimately affect many interconnected, production systems.
How bad is Docker Doomsday?
Well, it’s CVE 2019-5736 and has an overall Common
Vulnerability Scoring System (CVSS) value of 8.6, that’s on a scale of 1-10
where 10 is as bad as it gets. Another perspective comes from RedHat. They
classified it as “Important Impact”, a category reserved for vulnerabilities
that can lead to unauthorized access to sensitive data, or a denial of service.
How to Solve for Docker Doomsday
Now the good news. Since the leading security vulnerability
scanners (such as Qualys and Nessus) can find Docker Doomsday, you can run a
scan and automatically import the vulnerability data into TrueSight
Vulnerability Management. There you can analyze it and leverage its integration
with TrueSight Server Automation to fix it, either on-premises or in the cloud.
If you want to go one step further, use BMC Helix Discovery to find “blind
spots” (cloud-based Docker instances that the scanners missed) to obtain a
complete picture of where Docker Doomsday exists.
If you are in Cloud Operations and use TrueSight Cloud
Security, you can scan your Docker instances and containers, find Docker
Doomsday, and fix it with a security patch using TrueSight Server Automation.
Thinking back to Benjamin Franklin, your ounce of prevention
is patching with BMC TrueSight Server Automation. But do it soon, time favors
the attacker, not the
defender.[Source]-https://www.bmc.com/blogs/find-and-fix-docker-doomsday-with-bmc/
