As digitalization transforms industries and business models, organizations increasingly are adopting modern software engineering practices such as DevOps and agile to become competitive in the modern marketplace. DevOps enables organizations to release new products and features faster, but this pace and frequency of application releases can conflict with established practices of handling security and compliance. This leads to the enterprise paradox to go faster and innovate but stay secure by avoiding compromises on controls.
However, integrating security into DevOps efforts (DevSecOps) across the whole product life cycle rather than being handled independently or left until the end of the development process after a product is released can help organizations significantly reduce their risk posture, making them more agile and their products more secure and reliable. When properly implemented, DevSecOps offers immense benefits such as easy remediation of vulnerabilities and a tool to mitigate against cost overruns due to delays. It also enables developers to tackle security issues more quickly and effectively. Getting security right from the start is important due to the growing dependence of companies on digital technologies that can make them more susceptible to cyberattacks, in which an attacker can utilize a system flaw possibly created due to unfamiliarity toward security as a business priority.
DevSecOps integrates various security challenges into the coherent approach of software delivery. Some best practices followed in DevSecOps throughout the software development life cycle are:
- Planning and Designing: From the inception, teams are aware of their security responsibilities and trained to handle them. Since the start teams quickly model threats and risks. Product backlog items (PBI) are prioritized in a way to make the product secure and compliant. Architectural design is developed in collaboration with security experts.
- Coding: Developers practice secure and resilient coding practices. Full advantage is taken of reusable coding patterns and microservices to meet common security requirements for encryption and authentication.
- Reviewing: Both automated and manual checks are used to review codes as part of regular agile sprints. After that, peer reviews are conducted by senior developers to make sure that software meets appropriate standards.
- Testing: Automated security tests are run alongside automated functional and performance tests to confirm that testing is consistent. Automated penetration tests look for security cracks in systems as part of every sprint and release cycle.
- Deployment: Automated processes are used to deploy code securely and reliably into production-hosting environments that can be rapidly invoked through APIs.
- Operations: In production, automated processes such as real-time monitoring, intrusion detection and compliance validation are used to detect vulnerabilities. Product reliability and security are constantly checked to detect vulnerabilities and prioritize resolutions.
The success of adopting DevSecOps principles relies on avoiding common pitfalls. The mere implementation of DevOps tools across the organization cannot support the effectiveness of DevOps. To get it right, companies need to:
- Create a more integrated operating model making privacy and security principles as integral parts of the company culture.
- Build secure and reliable services.
- Wherever possible, automate development and release processes.
- Continually evolve product architectures.
Leaders play an active part in steering the transformation by endorsing security and privacy at the board level. At the same time, CISO and compliance leaders need to make certain that greater agility does not come at the cost of higher risk.
Often organizations focus on software security as a business priority only after they are affected by a data breach. But when an organization is impacted by cybercrime, along with the costs of data damage, IP theft and business disruptions, it incurs legal and PR fees, drops in share price and the potential loss of customers and competitive advantage.
Companies that implement DevSecOps best practices benefit from numerous advantages. Substantial costs can be curtailed by detecting and fixing security issues in the early phases of development, which indirectly leads to an increased speed of delivery and recovery.
A secure and reliable product has the potential to increase sales. Following best practices leads to the creation of immutable infrastructure and utilization of cloud-based infrastructure that helps improve overall security by reducing insecure defaults, increasing code coverage and automation.
Automated application testing, automated security review of code and empowering developers to use secure design patterns ensure the “secure by design” principle. In DevSecOps the responsibility for security is shared and encourages a culture of openness and transparency from earlier stages of development and enables constant iterative improvements.
A central belief of DevSecOps is that security is an integral and essential aspect of DevOps. By adopting DevSecOps best practices in their product development cycles and avoiding common pitfalls, companies can stay current, acquire agility and strengthen their security to withstand exposure to cyberattacks.
