What makes you so sure about that? Probably not "random", but just
"damaged". If not harddisk failure, imagine memory failure or a
defective kernel process, anything like a single swapped important
byte in memory which causes the kernel to write a block to a wrong
location on disk.

But sure can you deny e.g. TCP SYN access to all unprivileged ports
and accept only incoming TCP reply packets and UDP. Note that the
new netfilter code (iptables) is much more mighty than ipchains.
