An Introduction to DevSecOps

Challenges without DevSecOps

Without integrating DevSecOps, businesses often struggle with similar issues, which can include but are not limited to:

·      Lack of focus on security during the development process

·      Quality of solutions can be compromised from a security perspective as all the focus is on feature deliverables

·      Poor quality and insecure product releases can damage reputation

·      Sensitive data is compromised due to a lack of security testing focus

·      Massive delays in uncovering critical vulnerabilities

·      Delays to delivery/release due to Security teams having to step in last minute to fix serious issues

·      Unravelling of hard work by DevOps team as the Product doesn’t pass security tests before release

Because Security Teams are normally kept out of the process until the last phase of development, critical vulnerabilities and security issues can remain undetected throughout the whole build, this often leads to rework, loss of resources, loss of time, and loss of money.

Advantages to Implementing DevSecOps

By bringing Development, Security and Operations teams together into one Agile process, businesses can quickly see big advantages in terms of communication, collaboration, and efficiency, which all assist the creation of a seamless end to end product delivery. These benefits include, but are not limited to:

·      Elimination of silos

·      Promotes collaboration and teamwork across departments

·      Aligns business goals and visions across departments

·      Identifies vulnerabilities early whilst still ensuring fast delivery

·      Contributes business value by reducing rework and increasing quality (which saves money, time, and resources)

·      Improved overall operations

·      Diminished security risks

Effectively, the team can then spend more time adding value to end customers and less resources fixing and managing security vulnerabilities or security exploits.

How to implement DevSecOps

The biggest challenge in implementing DevSecOps is a reluctance to integration and change. These business functions have been kept separate for a long time and therefore they have different processes, metrics, and tools that they are all used to using. Everyone would have to adapt to new work processes and also new working relationships with people who aren’t usually a part of that team. To achieve this it’s important to choose the right processes and the right tools (which will be business dependant) and also allow an adequate amount of time to make this transition gradually.

Sumo Logic suggests six easy steps to implement DevSecOps gradually, which are;

1. Use Agile methodologies to deliver code in small, frequent releases

2. Run automated tests wherever possible

3. Empower developers to suggest critical security changes

4. Real-time security compliance

5. Always be prepared for threats

6. Invest in training for newly formed DevSecOps teams

Conclusion

Security is a fundamental part of the Agile Product lifecycle. With DevSecOps, developers can better understand the criticality of vulnerabilities that exist in their code and fix these vulnerabilities earlier in the process, which helps them deliver products and solutions (still) fast, but more secure. This saves business resources, enables cross-department collaboration, and also protects the business's reputation by consistently delivering high quality, fast, and secure products.

In the next few weeks, I’m looking to host a webinar that explores the process, benefits and challenges of DevSecOps from market leaders in the space. If you’re interested in taking part, finding out more, or submitting your own questions, I’m really keen to hear from you. Feel free to drop me a message or comment anytime to discuss any of the above. I’d love to hear what your thoughts and experiences of DevSecOps is, and if it’s something you use in your business.
