Subject: previledge password in cisco routers

Sorry but cisco can only be blamed for so much. If you allow telnet to
your router from the internet...then how is that Cisco's fault? Or even
if you allow SSH from the internet...network protection is the key.
Software will have holes and problems with be found. Only thru good
network design and layered security will you be protected.

Server are open to attack also if you allow FTP, SSH and TS from the
internet...what do you think will happen?

SNMP strings are like gold..and very few people understand they need to
change them and guard them as such...but again that isn't cisco's fault.
Should you use the web interface to connect your routers? Well no..there
are problem with it...learn the command line and therefore the problem
doesn't exist.
