What are we seeing
Key Facts and Figures - Americas
• 2,200+ networks analyzed
• 1,600 applications detected
• 31 petabytes of bandwidth
• 4,600+ unique threats
• Billions of threat logs

applications are needed to run the
business?
Bandwidth Consumed


High in Threat Delivery; Low in Activity
 11% of all threats observed are code execution exploits within common
sharing applications
 Most commonly used applications: email (SMTP, Outlook Web, Yahoo! Mail),
social media (Facebook, Twitter) and file-sharing (FTP)

Low Activity: Effective Security or Something Else?
SMTP
IMAP
POP3
Web browsing
Smoke.loader botnet controller
 Delivers and manages payload
 Steals passwords
 Encrypts payload

seen in SMTP, POP3, IMAP
and web browsing.


Distributed computing = resilience

High number UDP ports mask its use

Multiple techniques to evade detection

Robs your network of processing power
Unknown UDP Hides Significant Threat Activity

1 application = 96% of all malware logs

ZeroAccess.Gen command & control traffic represents nearly all malware activity

Business Applications = Heaviest Exploit Activity
 90% of the exploit activity was found in 10 applications
 Primary source: Brute force attacks

Best Practices
Security from Policy to Application

What assumptions drive your security policy?

Does your current security implementation adequately reflect that policy?

Doss your current security implementation provide the visibility and insight
needed to shape your policy?

Application Visibility

Reduce attack surface

Identify Applications that
circumvent security policy.

Full traffic visibility that provides
insight to drive policy

Identify and inspect unknown
traffic
Identify All Users

Do NOT Trust, always verify all access

Base security policy on users and their roles, not IP addresses.

For groups of users, tie access to specific groups of applications

Limit the amount of exfiltration via network segmentation
