The Use of Malware Analysis in Support of Law Enforcement

One of the fundamental challenges to internet security is the use of technology to attack computer systems and steal the assets they contain. These assets include data (proprietary, intellectual, financial, personal, and classified) and resources (bandwidth, computing power, and storage space). This paper discusses how malware analysis supports the efforts...

Analysis-Resistant Malware

Traditionally, techniques for computing on encrypted data have been proposed with privacy preserving applications in mind. Several current cryptosystems support a homomorphic operation, allowing simple computations to be performed using encrypted values. This is sufficient to realize several useful applications, including schemes for electronic voting and single server Private Information...

An Adaptively Evolving Intrusion Detection System Using Pattern Recognition Techniques

With networking technology evolving so rapidly, computer security has been receiving a lot of attention in the recent years. Conventional intrusion detection methods in the field of computer security are anomaly detection and misuse detection - the former suffers from high false alarm rates while the latter lacks generalization capabilities...

Counter-Forensic Tools: Analysis and Data Recovery

Among the challenges faced by forensic analysts are a range of commercial 'Disk scrubbers', software packages designed to irretrievably erase files and records of computer activity. These counter-forensic tools have been used to eliminate evidence in criminal and civil legal proceedings and represent an area of continuing concern for forensic...

Modified Logistic Regression: An Approximation to SVM and Its Applications in Large-Scale Text Categorization

Logistic Regression LR has been widely used in statistics for many years, and has received extensive study in machine learning community recently due to its close relations to Support Vector Machines SVM and Ad-a-Boost. This paper uses a modified version of LR to approximate the optimization of SVM by a...

Compatibility Is Not Transparency: VMM Detection Myths and Realities

Recent work on applications ranging from realistic honeypots to stealthier rootkits has speculated about building transparent VMMs - VMMs that are indistinguishable from native hardware, even to a dedicated adversary. This paper surveys anomalies between real and virtual hardware and consider methods for detecting such anomalies, as well as possible...

Traffic Aggregation for Malware Detection

Stealthy malware, such as botnets and spyware, are hard to detect because their activities are subtle and do not disrupt the network, in contrast to DoS attacks and aggressive worms. Stealthy malware, however, does communicate to exfiltrate data to the attacker, to receive the attacker's commands, or to carry out...

Exploiting Network Structure for Proactive Spam Mitigation

E-mail has become indispensable in today's networked society. However, the huge and ever-growing volume of spam has become a serious threat to this important communication medium. It not only affects e-mail recipients, but also causes a significant overload to mail servers which handle the e-mail transmission. This paper performs an...

Asymmetric Gradient Boosting With Application to Spam Filtering

This paper proposes a new asymmetric boosting method, Boosting with Different Costs. Traditional boosting methods assume the same cost for misclassified instances from different classes, and in this way focus on good performance with respect to overall accuracy. Their method is more generic, and is designed to be more suitable...

SIFF: A Stateless Internet Flow Filter to Mitigate DDoS Flooding Attacks

One of the fundamental limitations of the Internet is the inability of a packet flow recipient to halt disruptive flows before they consume the recipient's network link resources. Critical infrastructures and businesses alike are vulnerable to DoS attacks or flash-crowds that can incapacitate their networks with traffic floods. Unfortunately, current...

Got Predictability?: Experiences With Fault-Tolerant Middleware

Unpredictability in COTS-based systems often manifests as occasional instances of uncontrollably-high response times. A particular category of COTS systems, Fault-Tolerant FT middleware, is used in critical enterprise and embedded applications where predictability is of paramount importance. This paper presents empirical data, from 7 different three-tier, FT-middleware applications, that shows strong...
