Previous attacks that link the sender and receiver of traffic in the Tor network (“correlation attacks”) have generally relied on analyzing traffic from TCP connections. The TCP connections of a typical client application, however, are often accompanied by DNS requests and responses. This additional traffic presents more opportunities for correlation attacks. This paper quantifies how DNS traff...

OBJECTIVES International evidence suggests the diabetes nurse specialist (DNS) has a key role in supporting integrated management of diabetes. We examine whether hospital and community DNS currently support the integration of care, examine regional variation in aspects of the service relevant to the delivery of integrated care and identify barriers to service delivery and areas for improvement....

Computer networks are constantly being attacked by malicious entities for various reasons. Network based attacks include but are not limited to, Distributed Denial of Service (DDoS), DNS based attacks, Cross-site Scripting (XSS) etc. Such attacks have exploited either the network protocol or the end-host software vulnerabilities for perpetration. Current network traffic analysis techniques empl...

AIMS To provide one of the diagnostic categories for distal diabetic polyneuropathy,several symptom scoring systems are available, which are often extensive and lack in validation. We validated a new four-item Diabetic Neuropathy Symptom (DNS) score for diagnosing distal diabetic polyneuropathy. METHODS We compared score characteristics of the generally accepted Neuropathy Symptom Score (NSS)...

The numbers of online social networking sites are growing rapidly. The social networking sites have redefined the way we interact online. Most of the social networking sties provide customizable personal pages to its members. During customization user may embed contents from different web sites that provide contents in a form of HTML embed codes. Thus a page may contain different contents from ...

We study the challenges of deploying DNSSEC on Domain Name System (DNS) name servers. DNSSEC, a defence mechanism for DNS, was designed to provide cryptographic assurance for DNS records against cache poisoning attacks. Although standardised more than 15 years ago, DNSSEC is still not widely deployed. Multiple efforts are focused on identifying deployment obstacles and it is generally believed ...

We performed statistical analysis on the total PTR resource record (RR) based DNS query packet traffic from a university campus network to the top domain DNS server through March 14th, 2009, when the network servers in the campus network were under inbound SSH dictionary attack. The interesting results are obtained, as follows: (1) the network servers, especially those providing SSH services, g...
