10 Primary Exploit Target: Browser Plug-Ins The majority of publicly released exploits are for browser plug-ins The top five most exploited browser vulnerabilities all target plug-ins Although most active exploitation focuses on older vulnerabilities, newer attack tools have automatic methods to incorporate the most recent exploits 10

17 The Attack Lifecycle Inherent in any computer program are vulnerabilities, or small cracks in the code, that allow things in that were not originally intended. 17

18 The Attack Lifecycle Inherent in any computer program are vulnerabilities, or small cracks in the code, that allow things in that were not originally intended. A proof of concept, or exploit, is created to take advantage of the lowered defenses from the vulnerability 18

23 X-Force Protection Engines Cobion Cobion and content filtering technology has analyzed over 8.7B URLs and images and 1B unique spam messages. Over 100k web/700k spams analyzed daily. Shellcode Heuristics This engine uses generic shellcode detection to block shellcode payloads, one of the most prevalent method of infecting non-binary files like html, docs, and images. BOEP Buffer Overflow Exploit Prevention (BOEP) blocks execution payloads delivered through buffer overflow exploits, providing 0-day protection for this class of threats. PAM The Protocol Analysis Module (PAM) is the network IPS component in IBM ISS desktop, server, and network products. PAM uses behavioral and vulnerability-centric methods to detect and block network-based exploits affecting more than 7,400 vulnerabilities. VPS The Virus Prevention System (VPS) is a behavioral anti-virus technology that can stop not only new malware variants, but also new malware families. VPS uses pre-execution behavioral analysis to stop malware before it can run and do damage. 23

24 Conclusions The costs of data loss are significant but hard to calculate: the whole company is at risk. Collaboration brings complexity and with it many new risks. Statistics are showing how the endpoint and the data are targeted. A complete solutions must entail intrusion and extrusion prevention, as well as proper Authentication, Authorization and Accounting. 24
