Unfortunately, container security is much more difficult to achieve than security for more traditional compute platforms, such as virtual machines or bare metal hosts. Application developers commonly leverage open-source software when building containerized applications. So far, their prediction seems to be spot-on.

Vulnerability assessment is the process of identifying, quantifying, and prioritizing the cybersecurity vulnerabilities in a given IT system. The goal of an assessment is to locate weaknesses that can be exploited to compromise systems. NMAP is an example of a well-known open-source network scanner. Analyze findings.

In order to overcome these issues, the concept of paging and segmentation was introduced, where physical address space and virtual address space were designed. Here, virtual(logical) to physical address translation is much easier as segment tables store adequate information. A detailed description of these concepts is below.
