Why is security traditionally so hard?
Lack of
visibility
Low degree
of automation

The most sensitive workloads run on AWS
“With AWS, DNAnexus enables enterprises worldwide to perform
genomic analysis and clinical studies in a secure and compliant
environment at a scale not previously possible.”
— Richard Daly, CEO DNAnexus
“The fact that we can rely on the AWS security posture to boost our
own security is really important for our business. AWS does a much
better job at security than we could ever do running a cage in a data
center.”
— Richard Crowley, Director of Operations, Slack
“We determined that security in AWS is superior to our on-premises data
center across several dimensions, including patching,
encryption, auditing and logging, entitlements, and compliance.”
—John Brady, CISO, FINRA (Financial Industry Regulatory Authority)

“CIOs and CISOs need to stop obsessing over
unsubstantiated cloud security worries, and instead apply
their imagination and energy to developing new
approaches to cloud control, allowing them to securely,
compliantly, and reliably leverage the benefits of this
increasingly ubiquitous computing model.”

AWS Config Rules
Create rules that automatically take action in response to changes in your
environment, such as isolating resources, enriching events with additional
data, or restoring configuration to a known-good state
AWS Lambda
Use our serverless compute service to run code without provisioning or managing
servers so you can scale your programmed, automated
response to incidents
During an incident, containing the
event and returning to a known
good state are important elements
of a response plan. AWS provides
the following
tools to automate aspects of this
best practice.

“I have come to realize that as a relatively small organization, we can be far more secure in the cloud and
achieve a higher level of assurance at a much lower cost, in terms of effort and dollars invested. We
determined that security in AWS is superior to our on-premises data center across several dimensions,
including patching, encryption, auditing and logging, entitlements, and compliance.”
• Looks for fraud, abuse, and insider trading over
nearly 6 billion shares traded in U.S. equities
markets every day
• Processes approximately 6 terabytes of data
and 37 billion records on an average day
• Went from 3–4 weeks for server hardening
to 3–4 minutes
• DevOps teams focus on automation and tools to raise the
compliance bar and simplify controls
• Achieved incredible levels of assurance for consistencies of
builds and patching via rebooting
with automated deployment scripts
