DNSCrypt is a network protocol that authenticates and encrypts Domain Name System (DNS) traffic between the user's computer and recursive name servers.DNSCrypt wraps unmodified DNS traffic between a client and a DNS resolver in a cryptographic construction, preventing eavesdropping and forgery by a man-in-the-middle.
A proxy auto-config (PAC) file defines how web browsers and other user agents can automatically choose the appropriate proxy server (access method) for fetching a given URL. A PAC file contains a JavaScript function FindProxyForURL(url, host) .
Apple has made the source code of the Bonjour multicast DNS responder, the core component of service discovery, available as a Darwin open source project. The project provides source code to build the responder daemon for a wide range of platforms, including Mac OS 9 , macOS , Linux , *BSD , Solaris , VxWorks , and Windows .
The Neighbor Discovery Protocol (NDP), or simply Neighbor Discovery (ND), is a protocol of the Internet protocol suite used with Internet Protocol Version 6 (IPv6). [1]: §1 It operates at the internet layer of the Internet model, [2] and is responsible for gathering various information required for network communication, including the configuration of local connections and the domain name ...
Firefox for Android prior to version 79 did not properly validate the schema of the URL received in SSDP and were vulnerable to remote code execution. An attacker on the same network could create a malicious server pretending to be a device supporting casting, but instead of a configuration file it would return an intent:// URL. Firefox would ...
When a client uses domain fronting, it replaces the server domain in SNI (unencrypted), but leaves it in the HTTP host header (which is encrypted by TLS) so that server can serve the right content. Domain fronting violates the standard defining SNI itself, so its compatibility is limited (many services check that SNI host matches the HTTP ...
DNS-SD (DNS Service Discovery [16]) allows clients to discover a named list of service instances and to resolve those services to hostnames using standard DNS queries. The specification is compatible with existing unicast DNS server and client software, but works equally well with mDNS in a zero-configuration environment.
DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks .
