Por admin Practices for Security in the Software Development Lifecycle. Security practices in each stage of the SDLC involve requirements analysis through maintenance, practices that allow early risk identification and mitigation, cost reduction, and prevention of security issues in production.
Security analysis from the start helps identify the security requirements the application must meet, considering GDPR or PCI-DSS regulations, internal policies, and security practices.
Risk Assessment
Conduct regular analysis to understand the threats and vulnerabilities that could affect the application.
Assign Security Roles
Ensure that everyone involved in the project, such as developers, architects, testers, and others, understands their security responsibilities.
Risk Evaluation
Evaluate potential threats and vulnerabilities that could impact the application and prioritize implementing security controls and resources in the areas of highest risk.
Secure Development
Secure Coding: Train developers in secure coding techniques and the use of libraries and security tools that must comply with OWASP security standards.
SECURITY TESTING
Security Testing
Penetration Testing (Pentesting): Perform penetration tests to simulate attacks and detect exploitable vulnerabilities in the system. These tests should be conducted in an environment that simulates production.
Automated Security Testing: Implement dynamic analysis (DAST) and static analysis (SAST) tools that perform automated security tests and help identify vulnerabilities in different parts of the system.
Specific Vulnerability Testing: Run tests for specific vulnerabilities, such as XSS (cross-site scripting), CSRF (cross-site request forgery), or code injection, depending on the nature of the application.
Security Regression Testing: Ensure that security patches do not introduce new vulnerabilities into the system. This is crucial when applying updates or code improvements.
5. Secure Implementation
Secure Environment Configuration: Ensure that the production environment is adequately configured, eliminating unnecessary permissions and accesses and applying security settings (e.g., in databases, networks, and servers).
Infrastructure Security Scanning: Before deployment, conduct a full scan to verify that the environment is free of known vulnerabilities.
Access Management: Implement robust access and authentication controls in the production environment. This includes restricted access permissions to servers, databases, and network configurations.
Pre-Deployment Security Review: Conduct a final security review to validate all applied measures and confirm that the system is ready to be deployed securely.
6. Maintenance and Continuous Monitoring
Security Monitoring: Implement monitoring and intrusion detection tools to identify suspicious activities in the production environment and alert security teams.
Patch and Update Management: Regularly apply security patches to software and external dependencies, keeping the system up to date against new vulnerabilities.
Periodic Audits and Reviews: Regularly conduct security audits to assess the effectiveness of implemented controls and detect possible breaches.
Incident Response: Have a security incident response plan that defines procedures to detect, mitigate, and resolve potential issues if a security breach occurs.
7. Security Culture in the Company
Continuous Training: Continuously train the entire team on security topics and changes in regulations or security practices.
Promote Shared Responsibility: Foster a culture where everyone involved in the development and maintenance of the software feels responsible for the product’s security.

Security Policies and Practice Review: Ensure that security policies exist and are regularly reviewed and updated to adapt to changes in the threat environment. Practices for Security in the Software Development Lifecycle.
