Security Implementation

Network System Architects helps organizations improve their security
 postures by building better network and system architectures. The ways we
 do that are:

  • Designing secure network architectures
  • Implementing network firewalls
  • Designing and implementing secure dial-up access into your network
  • Designing and implementing secure Virtual Private Networks (VPN’s)
  • Securing Unix, Linux, Microsoft Windows, and NetWare servers

Designing secure network architectures

Where should your POP server be placed in your network architecture? 
Do you know? Network System Architects can help you. We will meet with 
your staff to create an overall vision of the services provided by your 
existing network. We will then create a network architecture that provides 
these services in the most secure manner possible without limiting
functionality to your users.

Implementing network firewalls

Installing a firewall involves a great deal more than installing 
software. What ports should you allow? What ports should you deny? What
 ports are the applications on your network currently using? Network System 
Architects’ experienced and certified staff can help you answer those
 questions.

Designing and implementing secure dial-up access into your network

At Network System Architects we have found that many of our clients
 protect themselves from the Internet using firewalls, but then allow
 ordinary dial-up modems to be attached to critical servers inside their
 network security perimeter. This gives hackers an easy backdoor into their 
networks.

A properly designed and configured dial-up access server can improve
 the security of your network, while at the same time reducing costs to your
 organization.

Designing and implementing secure Virtual Private Networks (VPN’s)

Virtual Private Networks (VPN’s) use secure encryption to securely 
transport your date across insecure network links. What this means to you
is that you can cancel your expensive leased lines and send your data
 across the Internet, securely and inexpensively.

Securing Unix, Linux, Microsoft Windows, and NetWare servers

Many corporate networks are like M&M’s; hard and crunchy on the
outside but soft and gooey on the inside. Once the hacker gets past the 
perimeter firewall, there is little to prevent him from doing whatever he
wants. And if the hacker is a disgruntled employee, there is no protection
at all.

Host based security is an important part of any data security plan.  Network System Architects will help you make certain your critical systems 
stay one step ahead of security vulnerabilities caused by Operating System
 bugs. Network System Architects will also review the configuration of your 
critical systems to make certain that no vulnerabilities have been created
 that will open them to attack.
