What your team learns
Build security into the whole application.
Prevent vulnerabilities
Choose technologies and development practices that remove the root causes of vulnerabilities. Back them up with layers of protection.
Contain a compromise
Limit what accounts and components can reach and do. Build trust boundaries that protect the rest of the application when one part is compromised.
Detect and respond
Make attacks visible. Use monitoring and automatic defenses to stop repeated abuse, and retain the evidence your team needs to respond.
Cloud and Git
Fix the cloud and Git setup too.
