Many of the security options in RFC 2617 are optional. If quality-of-protection (qop) is not specified by the server, the client will operate in a security-reduced legacy RFC 2069 mode; Digest access authentication is vulnerable to a man-in-the-middle (MITM) attack. For example, a MITM attacker could tell clients to use basic access ...
The string "localhost" will attempt to access the file as UNC path \\localhost\c:\path\to\the file.txt, which will not work since the colon is not allowed in a share name. The dot "." The dot "." results in the string being passed as \\.\c:\path\to\the file.txt , which will work for local files, but not shares on the local system.
Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography.SSH client programs (such as ssh from OpenSSH) typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory (e.g., .ssh/id_rsa).
Application-Layer Protocol Negotiation (ALPN) is a Transport Layer Security (TLS) extension that allows the application layer to negotiate which protocol should be performed over a secure connection in a manner that avoids additional round trips and which is independent of the application-layer protocols.
Given its URL, the attributes of a service can be requested. In standard SLP the attributes are not returned in the query result and must be fetched separately. The Attribute List Extension (RFC 3059) fixes this problem. A list of all service types can be obtained; A list of all existing scopes can be requested.
This version offers improved security and new features, but is not compatible with SSH-1. For example, it introduces new key-exchange mechanisms like Diffie–Hellman key exchange , improved data integrity checking via message authentication codes like MD5 or SHA-1 , which can be negotiated between client and server.
In early May 2019, an update was deployed to Stack Overflow's development version. It contained a bug which allowed an attacker to grant themselves privileges in accessing the production version of the site.
In computer networking, localhost is a hostname that refers to the current computer used to access it. The name localhost is reserved for loopback purposes. [1] It is used to access the network services that are running on the host via the loopback network interface. Using the loopback interface bypasses any local network interface hardware.
