Bolstering Container Security to Minimize Cyber-Attack Threats

26
A resilient container security protocol is one of the most effective ways to minimize exposure to various cyber-attacks and other inherent vulnerabilities. 

Enterprises globally are upgrading their tech stack to scale their business, enhance supply chain management and respond to disruptions effectively. Businesses need to be agile, efficient, and resilient against any cyber-attacks or disruptions. Integrating containers in the enterprise tech stack will help businesses to be up and running faster to streamline operations. 

Embracing containers is one of the most effective ways to overcome all the traditional virtualization challenges. However, the implementation of containers into the enterprise tech stack can expose the IT infrastructure to substantial security risks. 

CISOs should consider designing and implementing resilient security strategies to identify and mitigate threats. There are many container security vendors that enhance security and protect organizations from significant cyber-attacks. A recent Global Container Security Market Size, Share & Industry Trends Analysis Report  by Research and Markets forecasts that the global container security market size might reach USD 3.9 billion by 2027, scaling at a 23.5% CAGR during the forecasted period from 2021-2027. Even small data breaches can have a significant impact on business productivity and disrupt cash flows. 

Here are a few top container security strategies that CISOs can consider to strengthen end-to-end containerization:

Vigilant access management

It is crucial to secure all the container images on the business network. Maintaining a private registry will enable organizations to seamlessly execute role-based access management. Furthermore, it will enable enterprises to assign relevant metadata to the container to identify and monitor known vulnerabilities. Organizations can maintain a container registry to automate and implement policies for the images stored and reduce human errors that expose the container environment to various cyber-attacks. Determining what type of role-based access management controls are required to manage container images is essential to strengthening container security.

CISOs should consider evaluating their tagging capabilities to sort images. It is crucial to understand if the system is able to tag the images as approved only for development, testing, and production to understand the challenges. Analyzing end-to-end container management will assist the SecOps teams in understanding the potential vulnerabilities. Patching all the potential attack surface areas in all the containers will help to increase the enterprise’s container security. 

Ingrain resiliency to defend from cyber-attacks

Leveraging the isolation offered by the containers node Operating System (OS) will help businesses to add another layer of container security. Enterprises need to integrate a host OS that helps them to get maximum container isolating capabilities. It is one of the most effective ways to develop cyber resiliency in container deployment environments. Because node OS is designed to monitor container run executed by an orchestration tool, businesses that want to strengthen their container security can integrate network namespaces to sequester apps and ecosystems and attach storage via secure mounts. 

CISOs should consider using API management platforms that have authentication and authorization, endpoint access management, and rate limiting to ingrain security in containerization. Determining what containers require access to another and the discovery process will help to streamline the information flow. Designing and implementing role-based control access management of shared resources is essential to limit unauthorized access. Enterprises need to verify all the containers by regularly scanning the ecosystem to identify malicious files or images. Cyber attackers develop malicious containers and deploy them in known repositories to infiltrate the business network. CISOs should consider analyzing end-to-end container ecosystems to develop cyber-resilient enterprise container security strategies to protect the IT infrastructure from various risks.
