Recently, Amazon AWS introduced the new feature EC2 Serial Console for instances using Nitro System. It provides a simple and secure way to perform troubleshooting by establishing a connection to the serial port of an instance. Even though this feature is useful in case of break glass situations, from a security perspective, it could be used by adversaries to gain access through an unguarded secondary entrance.
Welcome to another monthly update on what’s new from Sysdig. Ramadan Kareem to all observing the holy month of Ramadan. Our team continues to work hard to bring great new features to all of our customers, automatically and for free! This last month was a big month for security with our release of Cloud Security Posture Management (CSPM), and we had lots of fun designing and releasing our new Cloud Chaos game!
The CVE-2021-20291 medium-level vulnerability has been found in containers/storage Go library, leading to Denial of Service (DoS) when vulnerable container engines pull an injected image from a registry. The container engines affected are: Any containerized infrastructure that relies on these vulnerable container engines are affected as well, including Kubernetes and OpenShift.
Monitoring AWS RDS may require some observability strategy changes if you switched from a classic on-prem MySQL/PostgreSQL solution. AWS RDS is a great solution that helps you focus on the data, and forget about bare metal, patches, backups, etc. However, since you don’t have direct access to the machine, you’ll need to adapt your monitoring platform.
Detecting malicious processes is already complicated in cloud-native environments, as without the proper tools they are black boxes. It becomes even more complicated if those malicious processes are hidden. A malware using open source tools to evade detection has been reported. The open source project used by the malware is libprocesshider, a tool created by Sysdig’s former chief architect Gianluca.
This release brings 50 enhancements, up from 43 in Kubernetes 1.20 and 34 in Kubernetes 1.19. Of those 50 enhancements, 15 are graduating to Stable, 14 are existing features that keep improving, and a whopping 19 are completely new. It’s great to see old features, that have been around as long as 1.4, finally become GA. For example CronJob, PodDisruptionBudget, and sysctl support.
GCP audit logs are a powerful tool that track everything happening in your cloud infrastructure. By analyzing them, you can detect and react to threats. Modern cloud applications are not just virtual machines, containers, binaries, and data. When you migrated to the cloud, you accelerated the development of your apps and increased operational efficiency. But you also started using new assets in the cloud that need securing.
Lateral movement is a growing concern with cloud security. That is, once a piece of your cloud infrastructure is compromised, how far can an attacker reach? What often happens in famous attacks to Cloud environments is a vulnerable application that is publicly available can serve as an entry point. From there, attackers can try to move inside the cloud environment, trying to exfiltrate sensitive data or use the account for their own purpose, like crypto mining.
