Communications between daemons and commands

Communications between LSF daemons and between LSF commands and daemons are not encrypted. If your LSF clusters are running in an untrusted or unsecured environment, these communications may be susceptible to interception and spoofing attacks. You can enable strict checking of communications to deal with spoofing attacks.
