Despite the growing adoption of the shift-left strategy in software development, challenges still persist. According to the 2022 Global C-Suite Security Survey Report from CloudBees, 83% of surveyed C-suite executives agree that shifting left is important, but 58% find it burdensome for their developers. Implementing shift-left programmatically is no easy task, and it requires intentional practices, guidelines, and playbooks for the entire team.
Embedding security earlier in the development process without adequate planning or support can lead to ineffective implementation. Organizations need to create a roadmap that outlines the necessary building blocks for a successful shift-left strategy, such as the DevSecOps architecture and policies. They should also take an iterative approach, starting with a pilot and expanding to more teams and software as they learn from their experiences.
One challenge that arises when discussing shift-left is the misconception that security responsibilities are being shifted entirely onto the development teams. However, the goal is to have developers and operations teams work jointly with security to ensure secure and high-quality software products. The term DevSecOps is preferred by some experts as it better represents the concept of integrating security into the development process.
Another concern that hinders the adoption of shift-left is the fear that it will slow down the development and release of software products. This fear is not limited to developers; even business leaders may share this sentiment. The traditional approach of leaving security reviews until the end of development can indeed cause delays. To overcome these concerns, CISOs must demonstrate that a shift-left approach can support both security and speed. Starting with small wins and showcasing the benefits can help convince stakeholders of its value.
Incentives play a crucial role in motivating developers and security practitioners to embrace a shift-left approach. Enterprise executives should provide the right incentives for teams to work differently and prioritize security early in the development process. Developers should have key performance indicators (KPIs) related to security, which requires a shift in mindset and organizational culture. Integrated KPIs that emphasize speed to market, performance, and security can help align all stakeholders towards common goals.
Acquiring the right talent is also essential for the success of DevSecOps/shift-left. While developers should not bear sole responsibility for security, they should understand the risks and collaborate effectively with security practitioners. Providing adequate training is crucial to ensure teams have the necessary skills and knowledge. Additionally, organizations should cultivate “security champions” who promote a security mindset and reward their efforts.
Having the right technology and tools is important, but it’s not enough. Security functions need to select tools that integrate well with existing development platforms and provide guidance to the teams on how to triage vulnerabilities. Simply throwing tools at the team without proper direction can overwhelm them and lead to anxiety. Security leaders should prioritize vulnerabilities based on enterprise risk factors and ensure clear communication between security and development teams.
In conclusion, while implementing shift-left in software development can bring numerous benefits, including lower security costs and faster issue resolution, challenges remain. Proper planning, support, incentives, talent acquisition, and technology selection are all crucial factors for a successful shift-left strategy. Overcoming these challenges will ultimately lead to improved security and efficiency in software development processes.
