Our security team is aiming for zero CVEs (Common Vulnerabilities and Exposures) in production, which sounds great in theory, but unfortunately, each of our containers is loaded with 120 to 150 vulnerabilities. We continuously scan and patch, but new CVEs appear almost daily. This situation is overwhelming; developers are frustrated, productivity is being affected, and distinguishing which vulnerabilities are genuinely concerning is a hassle. We also face a lot of false positives. Is it realistic to expect zero vulnerabilities in environments heavily reliant on containers, or should we instead focus on addressing critical vulnerabilities, improving our triage processes, and maintaining a secure production environment without exhausting our team? We're trying to navigate this challenging situation without burning out.

This is puzzling. You’d expect that the idea of containers is to have contained services that can be quickly rebuilt with the latest updates. If your devs are bundling everything into massive containers, that might be where the issue lies. It complicates updates and security management.
It's about control. If you’re lumping everything together, what you've really built is more akin to a VM. It defeats the purpose of using containers in the first place.
Chasing zero CVEs sounds great, but is nearly impossible in containerized systems. Focus on what’s exploitable, ideally with a robust risk management strategy. There are platforms that assist in prioritization, so leverage that to manage what matters.
Ultimately, your security team should be prioritizing critical issues. Zero vulnerabilities are a fantasy! Establish a clear line of communication with all teams involved to ensure that everyone is aligned in their understanding of security requirements and realities.
Exactly! And when it comes to vulnerabilities, it’s essential to have the context of your specific environment in mind when assessing risks.
Your situation is common. The key is to adopt a systematic patching schedule where you assess vulnerabilities based on severity. For example, prioritize medium and high vulnerabilities while regularly assessing your environment. Also, consider integrating automated tools that can help streamline this process.
Yes, hitting zero is unrealistic. I suggest you have a productive discussion with your security team. Aim for something practical, like targeting no unresolved critical vulnerabilities. Achieving a good understanding of which vulnerabilities are severe and manageable should help ease the stress on everyone involved.
That's key! It’s helpful to focus solely on critical vulnerabilities that could actually be exploited, rather than wasting time on low-risk vulnerabilities that won't impact your production.
Exactly! It's more about managing risk rather than an unattainable goal of total CVE elimination.
Keep in mind that not all vulnerabilities are threats. If they aren’t exploitable in your environment, you can lower their impact score instead of going for a full panic to patch every minor detail. Just make sure your key risks are adequately remediated.
One strategy to reduce vulnerabilities is to use hardened images. If your containers are bloated with unnecessary components, consider removing anything that isn't needed and use the smallest possible base image. This will help minimize your attack surface and the number of potential vulnerabilities.
Right! Even if you don’t want to rely on Docker’s official hardened images, alternatives like scratch or Alpine can really help. Plus, multistage builds can prevent a lot of build-time dependencies from reaching your production containers.
Exactly. Relying on large images, like Ubuntu, is a bad move if you're concerned about vulnerabilities.
Honestly, how did you end up with so many vulnerabilities in the first place? In my environment, even with complex setups, we only see around 10 vulnerabilities at most from third-party images and none in our custom builds. Are your developers using outdated practices or large monolithic containers instead of small, focused ones?
If security is really important in your sector, consider engaging professionals or looking into specialized security services that can help tailor your vulnerability management approach and take some of the burden off your team.
Or you could explore managed services that focus specifically on creating secure images and automating remediation processes for high-risk vulnerabilities.
Definitely! Investing in those services can help align your security practices with best standards without overwhelming your team.

Definitely! A web app can depend on hundreds of packages that can introduce vulnerabilities. If a package like RandomPythonPackage has a privilege escalation flaw but runs in an isolated container, it might not seem critical. But if those containers are not properly managed, you're opening yourself up to issues.
