_ Ursus Security and Network Designs _ 
Custom infrastructure computing, network and security solutions for your
unique requirements.
Experienced computing, network design/implementation with
stable & reliable infrastructure computing
switching/routing solutions, along with
appropriate data security.
Located in the central Texas. Established in 1996.
Over 15 years of Computing, Networking & Internet site management
experience.
Areas of Extensive Experience (spanning 15 years)
- TCP/IP security: including Firewall system designs and thorough
understanding of the standard IP protocol suite (TCP, UPD, ICMP), along with
the services that utilize these protocols; the knowledge of how to setup the
security infrastructure, such that unecessary exposure to attack is removed.
- A proven track record for both the design and implementation of
complex Local Area Networks (LANs), based on current high speed switching
technology (from a small scale LAN to a large scale campus environment) and
WAN network links, either dedicated, FrameRelay, fiberoptic or other
media/protocols, including the complexity of a multihomed Internet site
utilizing BGP4 and OSPF routing.
- An understanding of the strengths and the weakness of various
network technologies, including where each should be applied and where
each should be avoided, i.e. cell (ATM) versus frame based (various
Ethernet options) switching, routing versus switching, etc.
- The specifications and installation of various types of WAN links
via dedicated T1, HDSL, T3, dark-fiber or copper based FrameRelay; or
dynamic links as in ISDN.
- Selection, configuration and use of multiplexers, switches,
routers and the implementation of Security stateful packet filtering mechanisms
for TCP/IP networks. Specifically: extensive experience with the configuration
of Cisco routers (1750s, 2500s, 4700s,3660s, 7507s), including complex IP
packet filtering algorithms (with and without the Firewall feature set)
across multiple routers and interfaces, and with Cisco switches (Catalyst
1900s, 3100s, 3200s, 5000s, 5500s); PIX, OpenBSD & proxy based Sidewinder Firewalls.
- Use of either copper or fiber optic based solutions for
both LAN and WAN networks.
- Management of Internet connections and all the issues associated
with maintaining these links, i.e. ISP selection (very important), Domain Name
Services (DNS), current addressing conventions including classless interdomain
routing (CIDR), various routing protocols and matching bandwidth requirements
to link speed, multihomed sites, equipment options and associated cost.
- System Management of UNIX/Linux {Solaris, OpenBSD, RedHat}, VMS, MacOS and WindowsNT Server 4.0.
