Study Notes
- IaC security is a complex and challenging task
- Adhering to IaC security best practices minimizes security risks and avoids cyber attacks and breaches
- Security scans should be performed on IaC code to identify and correct misconfigurations
- Automating IaC security scanning helps identify and correct vulnerabilities
- Environmental/cloud drift is a threat to IaC security and should be prevented
- Code tampering is a threat to IaC security and should be avoided by hardening developers' access
- Avoid complexity in IaC code to reduce the likelihood of security issues or violations.
