Overview of Cloud Native Security
The Inner Workings of Cloud Native Security
First things first, let’s take a moment to unpack what ‘Cloud Native’ actually means. Born in the era of advanced digital innovations, cloud native refers to applications or software built specifically to thrive within the cloud ecosystem. Cloud native applications are characterized by modularity, being made up of smaller, independent components known as microservices. As for now, the question that looms head is – what does Cloud Native Security entail?
At surface level, Cloud Native Security might sound like securing just the applications run in the cloud ecosystem. However, this interpretation falls short, as it encompasses much more than just securing applications. Cloud Native Security is an end-to-end approach, touching upon every aspect of software development and deployment cycle. In essence, it represents the marriage of DevOps practices with security considerations, giving birth to the concept of DevSecOps.
Focussing on the lifecycle approach, Cloud Native Security breaks down its pursuit into four distinct phases: Develop, Distribute, Deploy, and Runtime. Unlike traditional security measures that often come into play only after development, cloud native security integrates security at every phase.
Develop phase: focus is placed on the security of the code. This includes implementing secure coding methods, regular code reviews, and continuous scanning for vulnerabilities.
Distribute phase: ensuring the integrity and confidentiality of the software supply chain takes center stage. This involves secure delivery of code, validation of code integrity, vulnerability scanning of built artifacts, as well as verifying and enforcing code signing.
Deploy phase: maintaining the security and integrity of the overall environment comes to play. This entails end-to-end infrastructure security, supported with configuration and secret management.
Runtime phase: focus lays upon securing the operations. It means continuous monitoring of the applications, infrastructure, and network, ready to respond to any security incidents.
Cloud Native Security also thrusts focus upon the principle of least privilege, which demands limiting access to resources strictly to those who need them for their tasks. This not only restricts potential attack vectors but also simplifies response measures in the event of an incident.
In conclusion, Cloud Native Security is far more than just securing applications in the cloud. It’s an all-encompassing, layered approach that integrates security into every phase of software development and deployment, with an insistence on continuous monitoring and the concept of least privilege.
As the cloud continues to pivot as an integral part of modern digital landscape, embracing Cloud native security turns indispensable for organizations looking to secure their invaluable data and applications. Glancing into the future, as the boundaries between technology and traditional sectors continue to blur, Cloud native security, encapsulated with DevOps and a lifecycle based security approach, will take precedence over legacy security methodologies.
