The four C’s of DevSecOps are essential security measures for protecting applications and data in cloud-native environments. Developers must focus on the rising application threats and consider the Cs to improve security measures.
Security in software development is increasing. Companies are investing more to better their software security measure. While developing software, developers make sure that there are robust security measures.
Importance of Rising Security Concerns
For robust security measures, four things matter the most
- the principle of security,
- its management, and
- skills to manage the overall ecosystem and
- protection of data.
The protection also covers risk management and compliance of data.
DevSecOps is responsible for building robust security in the software development cycle. It involves other concerns beyond security and patching. The security standards for DevSecOps are rising as threat intensity arises. With the help of modern tools and technologies, developers can raise the security bar.
Software development needs best practices for security due to factors such as agile development, open-source software, and cloud-native technologies. This is critical in the early stages of software development.
The size of the DevSecOps landscape creates a challenge for developers to determine the best-fit solutions for organizational software development. To help developers with this, here are the vital DevSecOps’s four C— Code, Container, Cloud, and Cluster. They must focus on these to implement the latest security solutions in all the stages of software development.
The Four C’s – Container, Cloud, Cluster, and Code
The four Cs are dedicated to code security. Secure coding is one of the necessary security concerns to safeguard software and its data. So, the C’s of DevSecOps will help developers to keep codes safer than before.
Cloud security runs in the infrastructure of the servers. Developers must collaborate with Cloud service providers (CSPs) to set up a secure cloud infrastructure. Businesses must consider the shared responsibility model of cloud security. This will help to check and configure security patches while keeping all data safe within the cloud services.
However, the most common security issues in cloud systems are misconfigurations and automation challenges. Here are a few ways these issues may occur.
Misconfigurations are usually configuration mistakes that cybercriminals can take advantage of. Many applications and services are created under default settings, which gets exposed easily. The risk of misconfiguration is increasing rapidly. That is why robust cloud security is imperative here.
Automation is ideal for improving the speed and efficiency of running new applications. However, its process can also have errors and security issues if not adequately monitored. Developers must be able to secure the different sides of their architecture efficiently.
Properly managed cloud security services provide businesses with native measures to keep data safer. These services are experts in cloud security and can help developers to implement and maintain effective security solutions.
Container security involves securing the container that includes cloud-native applications. The security process involves the latest patches, access control, and network usage that prevents cyber-attacks.
Developers can increase security for containers by securing the host operating system. It involves the configuration of runtime, continuously securing codes. It provides access to selected host resources and restrains unidentified logins. It also includes image security, which developers can use to increase security measures and identification of logins and access monitoring.
Developers must initiate cluster security by securing the infrastructure and applications running on the cluster. The security parameters address access controls, networks, and authentication.
Developers must secure a cluster by studying every component that builds the cluster, such as the master, codes, and worker nodes. Developers must implement access control to limit access to sensitive resources. They should also implement authentication mechanisms such as certificate-based authentication to verify the machines and the identity of users. Kubernetes, a popular cluster management tool, provides authentication for client certificates, service accounts, and bearer tokens.
Code quality and security are related. High-quality code is more secure than low-quality code. So developers must understand code vulnerabilities and use secure coding practices to ensure code security.
It is because even remote code vulnerability can weaken or exploit the applications, harming company products. Developers must implement code analysis tools to identify code vulnerabilities faster. These tools analyze the vulnerable code and find security flaws such as injection attacks, buffer overflow, and cross-site scripting.
So, to provide security to codes for these processes, developers must secure the coding process under stringent cloud security parameters. The parameters such as strong authentication mechanisms, encryption of data, implement access controls for resources.
The 4Cs of DevSecOps security are critical because if any of these are compromised, it may compromise the running applications. DevSecOps constantly requires a new security mindset and must update its software’s security process in production.
The Strategies to Implement
DevSecOps strategies will help applications protect data in cloud-native environments. Here are the strategies to follow:
Identify Security Risks
Developers must identify the security risks affecting applications, their codes, and ways to prevent them. They need to create a Platform-Based Security strategy to stay abreast of the evolving DevSecOps security trends. The strategy focuses on the stacks the application is built upon and covers overall platform security across all endpoints.
Securing Services and Components
Developers develop applications with the help of various services and components. So, securing those dependencies is critical. It is because threat actors use the vulnerabilities in components first to hit the entire application process.

Security into Software Development Lifecycle (SDLC)
Developers need to integrate security measures into the software development lifecycle (SDLC) from the early stage of development. Developers can reduce the risk of vulnerabilities immediately by identifying security issues early.
Shared Responsibility Model
Developers must focus on a shared responsibility model for security to recommend businesses for adequate application security. This will help all data and codes to remain under tight security layers. Only authorized official employees can get access to the model to access application codes.
Companies and developers must be more cautious and aware of rising security issues. That is why they must continuously review all the security processes and stay aware of updates to increase security measures. Also, they must review and audit existing applications and remediate existing infrastructure flaws. So, aligning a goal for DevSecOps in businesses will help accelerate security changes.
