Top Shift Left Security Best Practices CTOs Should Consider
These are key actions CTOs can take to include Shift Left security early and reduce risks in software projects.
1. Start Security Early in Development
Why it matters:
Identifying and fixing security issues early is faster, cheaper, and avoids final moment disturbances.
How it works:
Teams discuss potential risks during requirement gathering, create secure architecture plans, and apply basic checks during early coding. This helps identify problems before they reach testing or production.
Example:
A fintech company added code scanning during development and fixed a major vulnerability before release, saving both time and money.
2. Build a Developer-First Security Culture
Why it matters:
When developers understand application security automation and build it into their work, fewer issues reach later stages.
How it works:
Companies trained developers to write safe code, explain Common mistakes in shift left security implementation, and provide tools to check their code as they work.
Example:
An e-commerce platform trained its developers to reduce security-related bugs.
3. Upgrade Security in the CI/CD Pipeline
Why it matters:
Automation accelerates testing, reduces manual error, and keeps every setup secure without slowing delivery.
How it works:
Tools for shift left security in CI/CD pipelines. Each time code is changed or deployed, the tools check it for problems and stop unsafe code from being used.
Example:
A healthcare app integrated upgraded scans in its Azure CI/CD pipeline, detecting risks before production and avoiding costly final delays.
4. Use Threat Modeling in Development
Why it matters:
Finding possible ways attackers could target the system early helps teams fix problems before they become bigger and more expensive to fix.
How it works:
Before coding, teams check the system for risks like security breaches or unauthorized access and fix the most serious problems first.
Example:
An insurance company planned for possible risks during design and added strict access controls, stopping unauthorized access after the system launched.
5. Secure Open-Source Components
Why it matters:
Old or weak third-party libraries are usually attacked and can cause security problems in applications.
How it works:
Tools check all third-party parts for security problems. Risky or old parts are fixed or replaced, and regular checks help keep the system safe.
Example:
A logistics company used tools to find weak open-source libraries and fixed or replaced them before they could be attacked.
6. Safeguard Infrastructure as Code
Why it matters:
Cloud and containerized systems can be exposed by simple misconfigurations if security is not checked early.
How it works:
IaC templates are scanned during development for risky configurations such as open ports or broad permissions. Teams apply least-privilege rules and compliance policies as part of the build, so unsafe infrastructure never gets deployed.
Example:
A SaaS company checked its code before deployment and corrected cloud storage settings to protect data.
7. Track, Measure, and Continuous Improvement
Why it matters:
New vulnerabilities appear all the time, so constant monitoring helps keep systems secure and improves future processes.
How it works:
Dashboards track security issues, how quickly they are fixed, and problems that happen again. Teams use this to make future work safer.
Example:
A retail company used continuous monitoring to detect and fix a risky API exposure before attackers could exploit it.
