Protecting SSH at the Transport Layer
نویسنده
چکیده
SSH daemons are common targets for brute force attacks. Through log monitoring and firewalling, the impact of these attacks on both security and bandwidth consumption can be minimised. We consider a number of implementations and employ Stockade [1] as a backend to SSHGuard [2] for blocking attackers.

RFC 4344 SSH Transport Layer Encryption Modes January
Researchers have discovered that the authenticated encryption portion of the current SSH Transport Protocol is vulnerable to several attacks. This document describes new symmetric encryption methods for the Secure Shell (SSH) Transport Protocol and gives specific recommendations on how frequently SSH implementations should rekey.
متن کاملPacific decadal oscillation and sea level in the Japan/East sea
Satellite altimetric data from September 1992 to January 2002 and hydrographic data from 1927 to 1999 reveal the presence of low-frequency variability of sea surface height (SSH) within the Japan/East Sea (JES). SSH interannual variability amounting to approximately 15 cm is in phase with the Pacific Decadal Oscillation (PDO), with higher SSH, warmer, fresher surface (upper 200 dbar) layer duri...

متن کاملSecure Login Connections over the Internet
SSH provides secure login, le transfer, X11, and TCP/IP connections over an untrusted network. It uses cryptographic authentication, automatic session encryption, and integrity protection for transferred data. RSA is used for key exchange and authentica-tion, and symmetric algorithms (e.g., IDEA or three-key triple-DES) for encrypting transferred data. SSH is intended as a replacement for the e...
