Network Security Priorities For Containers, According To Today’s IT Pros

Cloud computing and the use of cloud-native architectures have revolutionized the way businesses operate, offering unmatched performance, flexibility, velocity, and innovation. However, as the adoption of containers and distributed applications increases, so does the sophistication of threat actors. New Distributed Denial-of-Service (DDoS) attack techniques targeting cloud-native and Kubernetes-based applications have emerged. Additionally, recently disclosed security flaws in Kubernetes have highlighted the potential for remote code execution with elevated privileges on Windows endpoints within a cluster.

To address these growing security concerns, Tigera, a leading container security and network solution provider, conducted a survey with over 1,200 users of Calico Open Source, the most widely adopted solution in this space. The survey aimed to understand the capabilities IT professionals require for container security and networking.

The survey revealed that the critical capabilities driving the adoption of container networking and security solutions include scalable networking, security policies, interoperability across different environments, and encryption capabilities. These features are essential for ensuring secure and efficient operations in cloud-native environments.

Another key finding from the survey is the need for improved network visibility in Kubernetes clusters and workloads. Poor visibility can lead to misconfigurations, leaving businesses vulnerable to ransomware attacks, data exposure, denial of service attacks, and unauthorized lateral movement. Traditional perimeter-based security solutions are insufficient in identifying and mitigating such threats, emphasizing the importance of workload-level visibility.

The survey also highlighted the importance of network security policy creation and deployment. Workload access control and secure egress access are vital for protecting containerized applications. The most popular types of security policies deployed by Calico users include workload access policies that limit pod-to-pod communication and secure egress access policies. These measures help prevent lateral movement of threats and contribute to compliance efforts.

Container security necessitates a multi-layered approach, encompassing security measures at the network, host, and application layers. Network security plays a crucial role in reducing the attack surface and protecting containers. Vulnerability management, configuration management, and deploying a runtime security solution are also critical to rapidly identify and mitigate intrusion attempts.

Overall, a defense-in-depth strategy is essential for comprehensive protection against various types of attacks. Today’s technology professionals understand the importance of deploying solutions that offer robust security measures in an increasingly challenging threat landscape.

In conclusion, as cloud-native architectures continue to evolve, organizations must prioritize the implementation of container security and networking solutions. This ensures the protection of sensitive data, mitigates the risk of attacks, and helps organizations comply with industry regulations. By embracing a multi-layered approach and leveraging critical capabilities such as scalable networking, security policies, and improved network visibility, businesses can effectively safeguard their cloud-native environments.
