Network: Old Methods vs. New Methods

• Port and protocol allow/block firewalling• URL filtering, black lists• Blacklisting of IP or range• Standalone signature based IPS• UTM: unified threat management• Web gateways/Proxy

• Visibility and Control• Application based firewalling• Integrated Threat Prevention• SSL decryption/inspection• Automated threat intelligence sharing• Sandboxing

Visibility and Control: Application based firewalling, SSL Decryption/Inspection, Integrated Threat Prevention

Sandboxing and Threat Intelligence…3 years later

Watchguard- Dimension (threat intel only)

CheckPoint - Threat Emulation(sandbox), ThreatCloud service (intel, MSP)

Cisco(Sourcefire) - Threat Grid and AMP

Palo Alto Networks – WildFire Threat Intelligence Cloud

McAfee – TrustedSource (threat intel only – IP/Domain)

Fortinet – FortiSandbox

FireEye – core product + Threat Intelligence

Endpoint: Old Methods vs. New Methods

• Signature matching• Heuristics• Kernel-level root-kit protection• Cloud based updates• Web threat protection• IP Reputation services• Registry cleaners

• Micro-virtualization• Task introspection• Process/App whitelisting• Automated threat intelligence• Exploit trapping• Sandboxing• Predictive math modeling• Either Prevent or Detect/Remediate

Are exploits really the problem?

99.9% of the exploited vulnerabilities were compromised more than 1 year after the CVE was published.

~50% of 2014 CVEs exploited fell within 2 weeks of announcement.

How does exploit trapping fare against a sophisticated APT?

17

Traps stops 0-day exploits without prior knowledge of them

Attacks LEAD with exploits

Nov 2014: Operation CloudyOmegaNov 2014: Dark Hotel campaignOct 2014: SandWormOct 2014: Hurricane PandaFeb 2014: Operation SnowMan (MS IE 0-day exploit)Sept 2013: Ichitaro Zero DayFeb 2014: IE 0-day, Watering Hole attackFeb 2014: ‘The Mask’ CampaignDec 2013: Operation KeyChangOct 2013: Egobot CampaignSept 2013: Icefog campaignSept 2013: EvilGrab campaignJune 2013: NetTraveler campaign

…this pattern repeats over and over again
