Earl Carter has always had a passion for solving puzzles and understanding how things operate. Mr Carter quickly learned that identifying security weaknesses is just like solving puzzles. Almost 20 years ago, he was introduced to network security when he accepted a position at the Airforce Information Warfare center in San Antonio, Texas. In 1998, Mr Carter starting working Cisco and became one of the founding members on the Security Technology Assessment Team (STAT). After spending 15 years identifying new security threats and assisting product teams in hardening their devices and software to mitigate those identified security threats, Mr Carter became a Threat Researcher for Cisco Talos. Now he spends his time hunting for new threats against live customer networks by examining various intelligence feeds and data sources. In addition to hunting for new threats, Mr Carter also writes blog posts and white papers on new threats as well as regularly presenting at security conferences on these issues. Among Mr Carter’s significant contributions to Cisco are multiple security patents and authoring three Cisco Press Security Books along with co-authoring three more Cisco Press Security Books.
