The Enterprise AWS Security Journey

Phase 1:

How do I move

to AWS?

Time

Experience

AWS Foundation Services

Compute Storage Database Networking

AWS Global

InfrastructureRegions

Configuration

Customer applications & content

Yo

uAWS and you share responsibility for security

You get to

define your

controls IN the

Cloud

AWS takes care

of the security

Control

Start with the 5 why’s of security

1) Why is security such a hot topic?

Because its important, and it’s hard

2) Why is enterprise security traditionally so hard?

Because so much planning is needed

3) Why so much planning which takes so long?

Because it requires so many processes

4) Why so many processes?

Because mistakes are easy

to make and hard to put right

5) Why are mistakes so hard to put right?

Lack of visibility Low degree of automation

So where does AWS come in?

AWS makes security

more agile

Lets you move fast while

staying safe

From this To this

Design & Deploy

Define sensible defaults

Inherit compliance controls

Use available security features

Manage templates - not instances

Operate & Improve

Constantly reduce the role of people

Reduce Privileged accounts

Concentrate on what matters

The Five Why’s at Work at AWS

AWS Security Team

Operations

Application Security

Engineering

Compliance

Aligned for speed

Security Ownership as part of DNA

• Promotes culture of “everyone is an owner” for security

• Makes security stakeholder in business success

• Enables easier and smoother communication

Distributed Embedded

Operating Principles

Separation of duties

Different personnel across service lines

Least privilege

Technology to automate operational principles

Visibility through log analytics

Shrinking the protection boundaries

Ubiquitous encryption

Log analysis at AWS

• Internal project at AWS to analyze internal log

traffic• Collecting 90TB of logs per day - ~70k EPS average

• Correlate with permissions

• Compress 10:1 and store in S3

• Less than a minute response time for 3 billion sequential

accesses

• Costing a fraction of off the shelf software

Log analysis data flow

Raw logs

Permissions

Amazon EMR

Amazon Glacier

Amazon Redshift

Amazon S3

Write to S3

Parse in EMR and

upload to Redshift

EC2 Instances

Analyze with standard

BI tools

Archive to Glacier

AWS CloudTrail

Encrypted

end-to-end!

What are we looking for?

• Unused permissions

• Overuse of privileged accounts

• Usage of keys

• Anomalous logins

• Policy violations

• System abuse

• ….

• Collect data once, many use cases

Infrastructure Security at AWS

• Bastion hosts for maintenance

• Two Factor Authentication

Benefits of Enterprise Security on AWS

Higher degree of visibility, transparency and accountability

Higher degree of trust and autonomy

Better ability to respond to business’ requirements for change

Agility in security leading to speed to market

St. James’s Place Runs 85 Percent of Its Applications on AWS

St. James’s Place is a U.K. wealth-management

company managing over £52 billion of client funds.

We were able to double our capacity

during the peak tax season, and then

contract it back down when it was no

longer required.

Andy Montgomery

Head of Division for IT Operations and Solution

Design, St James’s Place

”

“ Needed flexible IT resources that

could scale as customer base grows

50% every year.

Needed high level of data security and

compliance with Financial Conduct

Authority (FCA) regulations

Migrated 85 percent of its applications

to AWS and expects a full migration by

2016.
