Identifying sources that are hacking into your system by using various techniques in computer science and mathematics.
◦ ◦ ◦ To solve practical security problems networking and system techniques applied cryptography machine learning ◦ ◦ ◦ probability/statistics information theory graph theory
Assistant professor in the Department of Computer Science & Engineering PhD Georgia Tech, 2008
Automated collection and analysis of web based bot malware infections Interests include all aspects of network and system security. ◦ ◦ ◦ ◦ Internet malware detection, defense, and analysis Intrusion detection and anomaly detections Network security Web and social networking security
Short for malicious software, consists of programming (code, scripts, active content, and other software) Loss of privacy
In malware, a botnet is a collection of infected computers or bots
Secret writing Ciphertext ◦ ◦ The conversion of information from a readable state to apparent nonsense ATM cards Computer passwords
