Security breaches cost companies an average of $4.35 million in 2022. This staggering number emphasizes why traditional security approaches fail in today's ever-changing software development world. To address this challenge, organizations are increasingly turning to the concept of "shift left security" in DevSecOps.

But what is shift left security, and why is it crucial for modern software development? This article will explore the shift left meaning in the context of cybersecurity and its significance in the DevSecOps framework.

DevSecOps brings a radical alteration to the security approach in software development. Instead of treating security as an afterthought, security integration happens from the beginning of the development process. This "shifting security left" approach helps teams catch and fix security issues early in the software development life cycle (SDLC). As a result, it saves time and resources while building more secure applications.

This comprehensive guide will help you understand DevSecOps and the importance of shift left security for modern organizations. You'll learn about the business benefits of the shift left security approach, key tools and technologies, automation strategies, and real-world application examples. Whether you're new to DevSecOps or looking to improve your existing security practices, this guide will provide practical steps to enhance your security posture through a shift left strategy.

The Business Case for Shift Left Security

The economics of security tells a compelling story through numbers. Research proves that fixing vulnerabilities in production costs significantly more than addressing them during the design phase. This reality makes a strong business case for moving security practices earlier in the process, embodying the essence of the shift left security approach.

Cost Impact Analysis

Organizations that adopt DevSecOps and implement a shift left on security cut down their security expenses substantially. A major health insurance company saved $21 million from their yearly security budget of $28 million by detecting defects early in their development cycle. Teams that fix security issues early spend up to 90% less on fixes compared to production-stage remediation. These figures clearly demonstrate the financial benefits of the shift left security strategy.

Risk Mitigation Benefits

Companies with mature DevSecOps practices that have embraced the shift left security approach spot security incidents 2.5 times quicker - often within hours rather than taking days or weeks. This quick detection becomes vital since IT downtime costs reach $5,600 per minute. Organizations can significantly reduce their exposure to potential security vulnerabilities and associated risks by implementing shift left security testing.

Competitive Advantages

Moving security practices left creates several market advantages:

• Stronger customer trust in security capabilities
• Quicker secure product launches
• Better teamwork between development, security, and operations teams
• Stronger regulatory compliance with fewer penalty risks

It makes sense why shifting left leads to better outcomes. The earlier vulnerabilities are caught and remediated the less amount of internal rework and teams are needed to intervene. In addition, mitigating issues before production helps reduce the overall cost burden companies face between SLAs, regulatory fines and lawsuits. The data shows that DevSecOps-enabled companies face 50% fewer security breaches than others. This reduction leads to lower incident costs and fewer legal issues. A real example shows how Capital One cut down their critical vulnerability fix time from 18 hours to minutes, which proves massive efficiency gains achieved through the shift left security approach.

Essential Security Tools and Technologies

The right security tools are vital to successful DevSecOps adoption and implementation of a shift left security strategy. Let's look at the technologies that form the foundation of modern security practices in the context of shifting security left.

Secret Detection

Secret detection is a process used to identify sensitive information that has been accidentally exposed or embedded in application code, configuration files, or logs. These secrets might include:

• API Keys
• Access Tokens
• Passwords
• Encryption Keys
• OAuth Tokens
• Database Credentials
• SSH Keys

When exposed, these secrets can be exploited by attackers to gain unauthorized access to systems, APIs, or data. Secret detection tools or processes aim to mitigate this risk by scanning codebases, repositories, or runtime environments to flag and secure such sensitive information.

SAST and DAST Implementation

Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) are the lifeblood of security that shifts left. SAST tools scan source code, bytecode, or binaries to detect common security flaws, such as:

• SQL Injection
• Cross-Site Scripting (XSS)
• Buffer Overflows
• Hardcoded Secrets
• Poor Encryption Practices

Since SAST operates on non-running code, it can detect vulnerabilities as developers write or commit code, enabling fixes before deployment. SAST tools are incredibly important to companies required to adhere to specific compliance frameworks due to their support with standards like OWASP Top 10, PCI DSS, GDPR, and HIPAA.

DAST adds value by testing running applications and detecting problems that surface only during runtime. Both SAST and DAST are crucial components of shift left security testing, enabling early detection and remediation of security issues.

Container Security Solutions

Container security plays a vital role in modern DevSecOps practices and the shift left security approach. Containers are widely used for deploying applications due to their portability and scalability. However, they can introduce risks, such as:

• Vulnerabilities in the operating system or libraries included in the image.
• Misconfigured permissions or exposed secrets.
• Malicious code embedded in base images.

Container scanning helps detect and mitigate these risks before containers are deployed into production. A strong container scanning tool will support with the following:

• Base image security validation and trusted sources
• Runtime protection tools for behavioral monitoring
• Automated vulnerability scanning for container images

Infrastructure as Code Security

Infrastructure as Code (IaC) security helps you build consistent and secure environments, aligning with the shift left security strategy. IaC scanning detects potential cloud misconfigurations before changes go live. Companies who have implemented IaC security tools early in the development cycle substantially reduce misconfiguration risks in production.

Integration in the CI/CD workflow allows automated security checks at each stage, embodying the principles of shift left security by blocking misconfigs before they get costly in production. Tools like Codefortify provide comprehensive security analysis and cut vulnerability detection time by up to 50% compared to traditional methods, demonstrating the efficiency of shifting security left.

Security Automation Strategies

Security automation has pioneered the transformation for most companies evolving from DevOps to DevSecOps, and ultimately their adoption shift left security. Automation helps reduce the volume of manual vulnerabilities that need to be reviewed and auto-approve or auto-fail pipelines that don’t meet specific security requirements.

CI/CD Pipeline Integration

Integrating security into CI/CD pipelines is a key aspect of the shift left security approach and requires a systematic strategy. Teams can detect vulnerabilities before they reach production by implementing automated security checks. CI/CD security integration, aligned with the shift left security strategy, significantly reduces the amount of time development and security teams spend discussing vulnerabilities and in many examples has cut down the average remediation time for critical vulnerabilities from hours to just minutes.

Automated Remediation Workflows

Automated remediation focuses on enabling developers with self-service security tools, which offloads the responsibility of identification and remediation from the security team to the development team - a crucial element of shifting security left. This approach delivers substantial benefits:

• Reduced dependency on security teams
• Faster vulnerability remediation cycles
• Improved cross-team skill development
• Better visibility across the development lifecycle

Security Policy as Code

Security policy as code (PaC) serves as the foundation for a comprehensive automation strategy and supports the shift left security approach. Codifying security policies eliminates human interpretation errors and ensures consistent enforcement. PaC improves compliance monitoring substantially with up-to-the-minute detection of policy violations and automated security pipelines achieve continuous monitoring and validation of security controls. This method works especially well in container environments where automated scanning compares containers against vulnerability databases to detect potential security issues, further reinforcing the shift left security strategy.

Real-world Case Studies

Real-life implementations help us see how DevSecOps adoption and the shift left security approach work in practice. Success stories and experiences provide valuable insights into this approach.
