This seminar presentation discusses the Heartbleed vulnerability, which affected the OpenSSL implementation of the SSL/TLS protocols. It notes that many Android devices and Linux browsers were likely vulnerable, while iOS, Mac OS X, and browsers using Microsoft's SSL implementation were not. The presentation recommends continuous monitoring with IDS/IPS devices and vulnerability scans to detect any exploits of Heartbleed, and lists other potentially vulnerable devices like IP phones, routers, medical equipment and smart TVs.
