I'm considering using a service from papertrailapp.com (other similar services are loggly and splunk), where you configure your syslog to echo events to it over udp. It involves adding this entry to /etc/rsyslog.conf
*.* @logs.papertrailapp.com:12345 (where 12345 is a port unique to my account)
So my question is, is this secure? Couldn't someone sniff the traffic and watch the log output from my server?
