multiOTP is an open source PHP class, a command line tool, and a web interface that can be used to provide an operating-system-independent, strong authentication system. multiOTP is OATH-certified since version 4.1.0 and is developed under the LGPL license.
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).
The user authentication layer (RFC 4252) handles client authentication, and provides a suite of authentication algorithms. Authentication is client-driven: when one is prompted for a password, it may be the SSH client prompting, not the server. The server merely responds to the client's authentication requests.
To solve this problem, they use SCRAM, where Bob can store his password in a salted format, using PBKDF2. During login, Bob sends Alice his salt and the iteration count of the PBKDF2 algorithm, and then Alice uses these to calculate the hashed password that Bob has in his database. All further calculations in SCRAM base on this value which both ...
By default, SSH root password login is disabled to encourage the use of key-based authentication. SELinux continues to play a crucial role in enforcing strict security policies . Automation and Management The integration with Ansible allows for more streamlined automation and configuration management across systems .
PostgreSQL natively supports a broad number of external authentication mechanisms, including: Password: either SCRAM-SHA-256, [78] MD5 or plain-text; Generic Security Services Application Program Interface (GSSAPI) Security Support Provider Interface (SSPI) Kerberos; ident (maps O/S user-name as provided by an ident server to database user-name)
The Name Service Switch (NSS) is a feature found in the standard C library of various Unix-like operating systems that connects a computer with a variety of sources of common configuration databases and name resolution mechanisms. [1]
A server implements an HSTS policy by supplying a header over an HTTPS connection (HSTS headers over HTTP are ignored). [1] For example, a server could send a header such that future requests to the domain for the next year (max-age is specified in seconds; 31,536,000 is equal to one non-leap year) use only HTTPS: Strict-Transport-Security: max-age=31536000.
