What You Need to Know About Container Security
Security threats to compromise organizations are growing more serious, and as a result, it is becoming more crucial for enterprises to evaluate their system’s attack surface to pinpoint any potential vulnerability points.
Container security is a portion of thorough security assessments. It’s the practice of utilizing a combination of security technologies and rules to safeguard containerized apps from possible risk. In this article, let’s explore what you need to know about container security.
Container Security: An Introduction
Containers are software components that let you install apps as independent, self-contained packages that are separate from other machine activities. While virtual machines run a whole operating system, containers do not. As opposed to VMs, they have shared access to the OS kernel, making containers faster and lighter than VMs.
Related to security in typical systems, container security calls for a new strategy. The whole software development lifecycle must be integrated with a continuous security policy for containers. This entails protecting the build pipeline, host machines for containers, container images, runtimes for containers, and application layers.
Container security should be entirely automated due to a containerized environment’s complexity and dynamic nature. Implementing security controls as part of the continuous delivery lifecycle used to create and release container apps is a crucial step in automating security and integrating it into all phases of the SDLC.
Containers also offer another attack surface since they are susceptible to attacks that get around the host-to-container separation. By doing so, attackers can “break out” of a container, take over the host and get access to additional containers without authorization.
Container security is becoming a crucial part of any organization’s cybersecurity strategy as orchestrators and containers become more widely employed to run mission-critical systems and production applications.

Why Is Container Security important?
Over the past ten years, container implementation has increased dramatically. Containers are frequently used in software projects as small, lightweight blocks since they have all the components (code, tools, runtime, libraries, and configurations) necessary to run an application.
A container operates reliably each time, irrespective of the host machine’s environment, is relatively portable, and requires fewer resources than virtual machines. Being more conscious of container security is advantageous because different stakeholders are investing in it over various platforms, procedures, and programs.
Container security is concerned with all facets of safeguarding a containerized application and infrastructure. The improvement of IT security as a whole is accelerating due to container security. Organizations can improve security overall by mandating continuous security monitoring throughout production, development, and testing environments also known as DevSecOps.
Containers and Virtual Machines
Virtual machines and containers have certain commonalities, but they also differ significantly in several important ways. Containers contain only the application and all of the supporting operations. It is the best option for developing cloud-native applications because it is lightweight and simple to deploy across various environments.
A virtual machine may do many more operations and functions than a single container because it virtualizes the underlying hardware. While a virtual machine is larger than a container, it is not always preferable, particularly in the case of cloud-native development.
