Denial of service

Denial of Service attacks remain disturbingly prominent in the Internet, costing businesses in terms of both revenue and reputation. A well-prepared business must not only protect itself against accidental failures, but intentional and malicious attacks from determined adversaries as well. When systems are designed without security principles in mind, supplementary "add-on" security solutions need to be deployed - inflating the costs of operation. In the PADRES system Denial of Service resilience is integrated into the broker and overlay architecture.

This work is part of our ongoing research efforts to defend against DoS attacks in content-based publish/subscribe systems, and seeks to achieve the following benefits:

• Efficient response in isolating and dealing with threats to system availability

• Reliable operation continued in the face of malicious attacks

• Seamless integration of Denial of Service resilience mechanisms with standard publish/subscribe paradigm
