What is DevSecOps?
DevSecOps is all about introducing security in the earlier phase of the application or software development cycle and continuous integration, continuous delivery and continuous deployment pipelines (CI/CD), which helps to minimize vulnerabilities and meet IT and business objectives related to security and compliance. It mainly focuses on securing applications and automating security in the DevOps process. Good DevOps Security Tools and strategies are required to determine risk tolerance and conduct a risk/benefit analysis.
DevSecOps is a practice of implementing security at every step in the DevOps Lifecycle with DevSecOps Tools. According to the traditional method where penetration tests and vulnerability assessment were done after the build, DevSecOps is based on the concept of integrating security assessments and vulnerability tests at each point of the CI/CD pipeline. DevSecOps tools help in implementing security within the DevOps workflow.
DevSecOps is the answer to integrating various enterprise challenges into a coherent and effective approach to software delivery. A central tenet of DevSecOps Tools is that security is an integral and essential element of DevOps – the method by which enterprises innovate at speed and scale.
The DevSecOps Manifesto
- Leaning in over Always Saying, “No.”
- Data & Security Science over Fear, Uncertainty, and Doubt.
- Open Contribution & Collaboration over Security-Only Requirements.
- Relying on empowered development teams more than security specialists.
- Consumable Security Services with APIs over Mandated Security Controls & Paperwork.
- Business Driven Security Scores over Rubber Stamp Security.
- 24x7 Proactive Security Monitoring over Reacting after being Informed of an Incident.
- Shared Threat Intelligence over Keeping Info to ourselves.
- Compliance Operations over Clipboards & Checklists.
What's driving the DevSecOps Movement
As software continues to grow rapidly in IT, DevSecOps and DevSecOps Tools become the foundation of competitiveness in the modern marketplace. Every business must become an agile and innovative software delivery machine to survive. This leads all of us to the enterprise IT paradox: go faster and innovate. But always stay secure. Modern Applications are mostly “assembled.” Developers often use and download vulnerable open source components and application frameworks.
In the DevOps world, organizations are building applications faster than they have forgotten the Security aspect. Cloud platforms and continuous delivery life cycles often circumvent traditional security processes and checks.
Security Collaboration – it’s everyone's responsibility. Organizations must try to bring individuals of all abilities to a high level of proficiency in a short period of time.
DevSecOps, it’s going to enhance the purpose of DevOps. Taken From Article, A Quick Guide to DevSecOps Pipeline

It scans, identifies, profiles, and validates all configuration changes on the network to ensure that these configurations remain in known and trusted states.
Alerting Tools help organizations by providing and generating passive and active alerts. These are essential as whatever is observed by the Monitoring Tools and found suspicious should be conveyed to the appropriate personnel; else, having or not having Monitoring Tools will not matter if alerts are not generated. Alerting Tools also allow for teamwide communication and response. Some of the tools used are:
- Contrast Assess
- Contrast Protect
VictorOpsIt aims to provide incident visibility and cross-team communications (both broad and targeted) of issues and their status. It offers transparent and meaningful information to the users working outside their domain to work quickly and efficiently.

Let's see how and where to add security checks into a Continuous Delivery workflow.
- Lightweight, iterative threat modeling, and risk assessments.
- Static analysis (SAST) checking in the engineer’s IDE.
- Peer code reviews (for defensive coding and security vulnerabilities).
2. Commit Stage
- Compile and build checks, ensuring that these steps are clean and no errors or warnings.
- Try to identify risk in third-party components.
- Generating Alerts on the high-risk code.
- Automation of unit testing of security functions, with full coverage of code analysis.

- Automated deployment and release orchestration.
- Automated runtime asserts and compliance checks.
- Production monitoring/feedback.
- Runtime defense.
- Bug bounties.
- Learning from failure
- Depending on the risk and uncertainty profile of your organization and infrastructure, you shall need to implement these practices and controls.
Architecting Container Infrastructure for Continuous Security and Compliance
As organizations benefit from agility, scalability, and even migrating to containers and microservices, Security and compliance parameters are often overlooked—some of the most critical security listings for container infrastructure.
- Kernel Security
- Denial Of Service
- Image Security
- Credentials and Secrets
- Runtime Security
1. Kernel Security
When it comes to containers and microservices, all rely on a single kernel of the host machine. Most of the intrusions can be stopped if proper kernel security is implemented. This is really efficient for multiple reasons you probably know already, but from the point of view of security, it can be seen as a risk that needs to be mitigated
2. Docker Host and Kernel Security
If an attacker compromises your host system, then container isolation and security safeguards won’t make much difference. Besides, containers run on top of the host kernel by design.
- Make sure your host and Docker engine configuration are secure. Watry using the Docker bench audit tool to check configuration best practices.
- Keep your base system reasonably updated, subscribe to security news feeds for the os and any software installed for 3rd party repositories, like the container orchestration platforms.
- Using minimal, container-centric host systems like CoreOS, Redhat Atomic, RancherOS, etc.
- You can use Mandatory Access Control to prevent undesired operations both on the host and on the containers at the kernel level using tools like Seccomp or Selinux.
- Ensure you have the removed lethal kernel modules; packages such as xinetd and telnet can be lethal, and privileges and access should be ensured accordingly.
Security vulnerabilities can exist in OSS (Open source software) libraries that we import as much as we write. Tons of developers do programming every day, and manual code reviews don't scale. Here is the real power of DevSecOps lies. Click to explore about, Relationship of DevSecOps with CI/CD Pipeline
3. Distributed Denial Of Service
Distributed denial of service DDOS attacks are some of the most pervasive and difficult attacks to prevent. These kinds of attacks use many distributed endpoints and systems to flood a web domain, application, or service with an excess number of service requests or application calls.
Running penetration tests on software early in development is one way to thwart holes that enable L7 DDoS attacks.
The failed test requires a response. One such response is to build the software when the software fails the test automatically. If development can't move forward without fixing the security holes, the security holes will be fixed.
Developers should not have to do a lot of digging to uncover these methods. Use resources such as the Open Web Application Security Project ( OWASP ) clearly set these approaches apart and label each of them independently.
4. Image Security
Many images are available on different repositories on the internet doing all kinds of useful stuff. Still, if you pull images without trust, authenticity, or vulnerability scanning, you are running arbitrary software on your machine.
Certain parameters must be followed before using that docker image:-
- Where did the image come from?
- Do you trust the image creator? Which kind of security policy are they using?
- How do you know nobody has been tampering with the image?
Best Practices to follow
- Do not run unverified software and/or from sources you don’t explicitly trust.
- Deploy a container-centric trust server using some of the Docker registry servers in our Docker Security Tools list.
- Enforce mandatory signature verification for any image that is going to be pulled or running on your system.
5. Credentials and Secrets
Your software needs sensitive information to run, such as user password hashes, server-side certificates, and encryption keys. The microservices deployed on containers are plenty and may constantly be created and destroyed.
You need an automatic and secure process to share this sensitive info.
Best Practices to follow
- Do not use environment variables for secrets; this is a widespread yet very insecure practice.
- Do not embed any secrets in the container image. Like “The private key and the certificate were mistakenly left inside the container image.”
- Deploy a Docker credentials management software if your deployments get complex enough, Do not attempt to create your own ‘secrets storage’ unless you know really well what you are doing.
6. Docker runtime security monitoring
As we build Docker container images, we need to know exactly what goes into each container layer. We also must ensure that containers installed by third-party vendors do not download and run anything at runtime.
A Holistic Approach
Towards Automation and Continuous Security using DevSecOps Tools
DevSecOps is all about implementing security at every step in the DevOps Lifecycle. it is an approach to secure an application and infrastructure using DevSecOps Tools based on DevOps, making sure the application is less vulnerable and ready for user use. All things automated, and security checks started from the beginning of the application’s pipelines.
With DevSecOps Tools, it is easier to identify and mitigate vulnerabilities and deliver more secure products. It allows the organization to take a proactive approach toward security. DevSecOps Tools enables the development, safety, and operations teams to work closely and deliver better results within the same frame but with relatively fewer efforts. It also allows the organization to monitor the products for new security threats as DevSecOps tools can be easily merged into the CI/CD pipeline.
