The Operations network was moved from a mixed corporate and
operations network, to a divided set of secure networks.

I upgraded and re-configured firewalls to provide protection for
critical operations servers and separated services onto differing security
level PIX interfaces.

Configured Secure console servers for core routers and switches.

Re-Positioned insecure telnet access to the core routers and switches onto a secure management interface.

Replaced and upgraded web and SSH servers, adding https servers
and authorization to sensitive servers. Expanded DNS failover and management capabilities.

Added regular automated backups for servers and databases.
