Security Threat and Vulnerability Mitigation Patterns: A Case of Credit Card Theft Mitigation

Most attacks on computer and software systems are caused by threats to known vulnerabilities. Part of the reason is that one needs a lot of knowledge in developing secure systems, but it is difficult to obtain sufficient knowledge and use it correctly as security incident reports and security standards are...

Inputs of Coma: Static Detection of Denial-of-Service Vulnerabilities

As networked systems grow in complexity, they are increasingly vulnerable to Denial-of-Service DoS attacks involving resource exhaustion. A single malicious input of coma can trigger high-complexity behavior such as deep recursion in a carelessly implemented server, exhausting CPU time or stack space and making the server unavailable to legitimate clients....

Detection and Prevention Methods of Botnet-Generated Spam

Although anti-spam measures are improving, the spam volume is increasing due to the use of Botnets. Botnets facilitate an efficient generation and guaranteed delivery of large volumes of spam. Spambots, or spam-generating bots, use different transmission methods based on the network settings of the infected host. These methods include relaying,...

MashSSL: Towards Multi-Party Trust in the Internet

This paper first shows that several seemingly disparate problems, ranging from secure cross domain authorization to policy enforcement in enterprise mashups to MITM attacks on federation protocols, all have as their root cause a single missing primitive function. Specifically, when a user at a browser is simultaneously interacting with two...

Pharewell to Phishing: Secure Direction and Redirection Over the Web

The conventional wisdom has always been that users should refrain from entering their sensitive data (such as usernames, passwords, and credit card numbers) into httpor white pages, but they can enter these data into https or yellow pages. Unfortunately, this assumption is not valid as it became clear recently that,...

Regional Congestion Awareness for Load Balance in Networks-on-Chip

Interconnection Networks-On-Chip NOCs are rapidly replacing other forms of interconnect in chip multiprocessors and system-on-chip designs. Existing interconnection networks use either oblivious or adaptive routing algorithms to determine the route taken by a packet to its destination. Despite somewhat higher implementation complexity, adaptive routing enjoys better fault tolerance characteristics, increases...

Load Balancing for Reliable Multicast

New applications emerge along with the rapid growth of the Internet. Many functionalities other than packet forwarding are being proposed to be added into routers for supporting those new applications. Those functionalities significantly improve the performances of the applications, but they incur overheads on routers at the same time. It...

Local Recovery Solutions From Multi-Link Failures in MPLS-TE Networks With Probable Failure Patterns

MPLS TE Fast Reroute proposes a local protection mechanism to quickly reroute protected TE LSPs onto pre-computed and signaled bypass tunnels. This paper explores the case of multiple network element failure scenarios. The undesired complexity inherent to the multiple failure scenarios originates from the fact that those failure scenarios are...

A Local Data Abstraction and Communication Paradigm for Pervasive Computing

As sensor networks are increasingly used to support pervasive computing, this paper envisions an instrumented environment that can provide varying amounts of information to mobile applications immersed within the network. Such a scenario deviates from existing deployments of sensor networks which are often highly application-specific and funnel information to a...

Multiuser Limited Feedback for Wireless Multi-Antenna Communication

For a wireless multi-antenna network with a large number of users, the sum capacity scales at most linearly with the number of antennas and double logarithmically the number of users. Achieving this optimal capacity scaling potentially requires feedback of Channel State Information CSI from all users, leading to overflow of...
