Agenda

• Heartbleed – what is it, how did it happen, and how can it be used against you

• How to identify your business exposure

• What systems are vulnerable and what you can do to check for Heartbleed

• How Tripwire’s solutions work together on detection, prevention, and remediation for Heartbleed

4

What Is Heartbleed?

• OpenSSL vulnerability

• Affects 2/3 of Internet and more

• Active exploits in the wild

• You may have already been compromised

CVE-2014-0160

Heartbleed Is Not a Single “Bug”

20

There are Different Breeds of the Heartbleed Bug

21

The Heartbleed Bug Doesn’t Just Live in Perimeter Networks…

22

Heartbleed Also Thrives Inside Corporate Networks and Datacenters

Healing Heartbleed

If You Do Detect Heartbleed:

• Update OpenSSL to 1.0.1g+

• Contact the Vendor for a Fix

• Update or revoke your certificates as a precaution

• If appropriate, ask or require users to revise their passwords

44

Prevention Recap

.1

• Know What You Have and Where OpenSSL Lives

2• Check both Perimeter and

Internal Networks

3• Patch both Remote and Local

Vulnerabilities
