Alert fusion is a key problem in distributed intrusion detection system (DIDS). The paper proposes a distributed intrusion alert fusion scheme based on multiple keywords and routing infrastructure: distributed hash table (DHT). All the related alerts produced by local sensor can be routed and fused to their
by the keyword search method enabled in P2P networks; a typical P2P network uses query broadcast to enable keyword search and are not able to express impreciseness. These protocols and mechanisms can be reinforced by the use of fuzzy logic. We propose an architecture that integrates fuzzy queries and an inference
, Patrol Packet Protocol (PTP). This protocol allows users to enter a part of a required URL with keyword(s). Additionally, the ISP completely works with a new routing protocol, PTP. The result of the search is the short list of URLs that relevant to the entering search URL and keywords.
Mobility has become a keyword nowadays with the evolution of mobile devices market and proliferation of real-time services. IP Multimedia Subsystem (IMS) is a single, standardized service framework that supports voice, video, data and messaging services, but does not provide seamless mobility for packet based sessions
genuinely important logs that lead to serious problems due to the large volume and complexity of log data. We propose a log analysis system for proactive detection of failures. Our key observation is that the abnormality of logs depends on not just the keywords in the messages (e.g. ERROR, FAIL), but generation patterns such
Although the problem of spam detection in email is well understood and has been extensively researched, a significant portion of emails today are spam. A most widely used method to detect spam involves content filtering, where the spam detector scans the received email for keywords. However, the same approach cannot
Set the date range to filter the displayed results. You can set a starting date, ending date or both. You can enter the dates manually or choose them from the calendar.
