Detecting and Mitigating Security Anomaliies

Network and information security is of increasing concern as intruders utilize more advanced technologies, and attacks are occurring much more frequently. A simple intrusion can cause an enterprise financial disaster, a threat to national safety, or loss of human life. Network-based and computer-based intrusion detection systems (IDS's) started appearing some twenty years ago. Now, there are va...

Detecting and Mitigating Malware in Virtual Appliances

System administrators use application-level knowledge to identify anomalies in virtual appliances (VAs) and to recover from them. This process can be automated through an anomaly detection and recovery system. In this thesis, we claim that application-level policies defined over kernel-level application state can be effective for automatically detecting and mitigating the effects of malicious s...

Mitigating Drive-By Download Attacks: Challenges and Open Problems

Malicious web sites perform drive-by download attacks to infect their visitors with malware. Current protection approaches rely on blackor whitelisting techniques that are difficult to keep up-to-date. As todays drive-by attacks already employ encryption to evade network level detection we propose a series of techniques that can be implemented in web browsers to protect the user from such threa...

Mitigating the Degradation Effects of Fading Channels

This article emphasizes so-called Rayleigh fading, primarily in the UHF band, that affects mobile systems such as cellular and personal communication systems (PCS). The major elements that contribute to fading and their degradation effects in a communication channel are briefly summarized. Emphasis is then placed on methods for mitigating the degradation. Two examples of specific mitigation tec...
