The bottom line is people musn't think that a firewall is enough to fix a security problem. Security is an ongoing, operational task and not a one-off thing. A security policy needs to be constantly looked at and adhered to by the CEO all the way down to the tea lady. Additionally, last September, Mimos took to task IT managers and administrators in local companies, universities and government departments for being slack in securing their publicly accessible servers. The call came after it had identified a group of hackers from a local university as being responsible for breaking into and using 38 local and up to 30 foreign servers as launch pads for denial of service attacks and abuse on global chat networks.
Security is relative.
What might be secure to you might not be secure to me. It's been said the securest system is one that isn't connected to a network. I believe Mimos servers could be more secure but do keep in mind that as security increases, the ease of use and maintenance of the system decreases. Andrew explains that SSH is an UNIX-based command interface and protocol for getting access to a remote computer and is widely used by network administrators. SSH commands are encrypted and secure in several ways.
