Do you really expect people here, on this list to say "Use OpenBSD" or "Use Linux" or etc?
`Use NetBSD'
Use a toaster oven. Toaster ovens have excellent network security characteristics. For example, they are not susceptible to any IMAP-based buffer overflow attacks; additionally, current toaster ovens are not known to have any bugs in their TCP/IP stacks, nor have been vulnerable to any in the recent past (according to CERT advisories, anyway). Toaster ovens require console access to perform administrative functions (such as modification of temperature settings), but this will not impede deployment in a number of environment.
Toaster ovens may be vulnerable to a remote denial of service attack involving manipulation of power lines -- however, most operating systems running on standard hardware are also vulnerable to this attack.
I have found that my toaster oven has served me well for a number of years, and produces excellent grilled cheese sandwiches, which is far better than my pentium running FreeBSD, largely because the cooling fan on the pentium does too good a job. Go figure. Maybe if I get a pentium pro? Neither my FreeBSD box nor my toaster oven has suffered from a security problem in a while.
