Measurement Criteria:
Vulnerability Remediation: ≤24h for critical CVEs Penetration Testing: OWASP Top 10 compliance Audit Compliance: SOC2 Type II readiness
This whole system can connect to the AWS service, which would allow all the data of our user to become secure and stable. Through the AWS management give the access to the user who have the access to the exact whiteboard. This can avoid data missing and other questions. There are lots of function in AWS, help us to achieve better control this web page.
