Security Considerations
From SecureCRT
A session is a set of options that are assigned to a connection to a remote machine. These settings and options are saved under a session name and allow the user to have different preferences for different hosts.
A data path or circuit between two computers over a phone line, network cable, or other means.
Telnet is a protocol that provides an interface for communications between clients and servers.
The first version of the SSH protocol which provides a way to encrypt network traffic between a client and a server.
The second version of the SSH protocol which provides a way to encrypt network traffic between a client and a server, with a slightly different set of security features than the SSH1 protocol provides.
SSL is an acronym for the Secure Sockets Layer, a cryptographic communications protocol used to encrypt network traffic over the internet.
Security
Considerations
Session security depends on several factors, including whether the connection you are using to the host is a trusted connection. If it is not, consider whether private or confidential information will be sent and received. A Telnet session will transmit user ID, password and other sensitive or private information in an easily readable format.
For maximum security, DO NOT put passwords in the SecureCRT Script dialog or script file. Script dialog information is stored in the SecureCRT configuration file, which may be accessed by other users depending on how open access is to the computer on which SecureCRT is installed.
Maximum security and privacy on the internet and local networks requires the use of the Secure Shell Protocols (SSH1 or SSH2) or the Secure Sockets Layer (SSL) supported in SecureCRT.
Note that although SecureCRT does support the Telnet protocol, SecureCRT Telnet sessions that are not Telnet/SSL are not encrypted. Encrypted connections are achieved through the SSH1, SSH2, and Telnet/SSL protocols.
