• Automation removes the potential for human error
• It works around the clock, and on weekends and holidays
• Automation enables a self-healing environment
• Multiple incidents can be responded to in parallel
• It allows InfoSec and other teams to better utilise their time for
high-level security tasks
• All easily built and scaled using the power of AWS!

So how do we scale security?
19. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Step 1: Detect Step 2: Assess Step 4: Notify
How can we detect
specific events of
interest, such as
key configuration
changes in AWS?
How can we
assess selected
assets against
known security
baseline
policies?
Step 3: Remediate
How can we
treat identified
deviations from
security policy?
How do we
notify the
affected people
and maintain
traceability?
The problem(s)
20. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Detect: Examples
AWS CloudTrail configuration changes
Route Table changes
AWS RDS encryption enabled
Security Group ingress rules
