The document discusses security in the cloud using Amazon Web Services (AWS). It notes that AWS provides strong security capabilities that allow customers to be more secure in the cloud than in their own data centers. It outlines how AWS offers security at no extra cost and discusses principles of security compliance, certifications, and tools available on AWS like Inspector, WAF, and CloudTrail to help customers with security. The document advocates for taking a security-by-design approach and leveraging AWS services and professional services to help customers prepare, prevent, detect, and respond to security issues in the cloud.

5. Security and Business Value
Security as a “Feature”:
• Qualitative measure: either secure or
insecure
• No added end user value
Objective Reality:
• Small or shrinking budgets
• Threat vectors and agents rising in
number and sophistication
Challenge:
How do we justify the cost of security?
