The service uses credentials provided in your authentication record for remote access to different command line services such as SSH, telnet and rlogin. The Clear Text Password setting in your record determines whether your credentials may be transmitted in clear text when connecting to services which do not support strong password encryption.
Your password will not be transmitted in clear text. The scanning engine only uses strong password encryption for remote login. This setting may prevent the scanning engine from detecting some vulnerabilities on hosts which do not support strong password encryption.
Your password may be transmitted in clear text. The scanning engine uses strong password encryption for remote login, if possible, and falls back to transmitting credentials with weak encryption or in clear text for services which do not support strong password encryption. Important: If these credentials are intercepted by a malicious person, then they may be used to completely compromise a host for attack and theft of information. It is recommended that you replace unsecured services, such as telnet and rlogin, with a secured SSH service. If you must operate unsecured command line services, it is recommended that you operate them within a secured tunnel like SSL/TLS or VPN.
