You may have a better understanding of the many security features that can be implemented with Kubernetes by reading the blog post that I wrote previously. Let’s talk about why logging and monitoring are essential to the safety of Kubernetes in this blog post, shall we? First things first: before we get into the specifics of why logging and monitoring are essential, let’s have a firm grasp on what they actually are.
Logging is a technique that stores or records the events of any operation that has been carried out digitally within an organization. Logging can refer to either storing or recording the occurrences. Therefore, if anyone logs onto their internal portal or participates in any of the activities, everything is being logged, which means that the records are being kept within a text file. The only method that can demonstrate both the identity and the integrity of the occurrences is logging. A log can contain a variety of important information, including the initiator, the source IP address, the date and time of the events, the source port, the destination port, and the device address, among other things.
Monitoring is the process through which a company tries to identify any harmful or unintentional behavior that may be occurring inside or outside of the organization as well as any developing threats. Because monitoring is so important, most companies these days are investing in SIEM hardware so that they can carry out centralized monitoring. This enables them to better keep track of their systems.
Now We are aware of the significance of accurate logging and monitoring within any infrastructure or organisation; however, when viewed from the perspective of Kubernetes, this becomes a whole other story. In most cases, we have a few layers such as pods, clusters, and so on, and each of these will generate their own unique set of logs. Due to the fact that these various components offer a great deal of potential avenues of exploitation as well, the resources need to be monitored appropriately. For monitoring purposes, organisations make use of effective tools and policies, enabling them to implement any necessary response in the event that harmful traffic is uncovered.
