On-site firewall and anti-virus installation
Many of the new appliance firewalls are easy to configure and install. However, particularly on a site which is connecting to the Internet at the same time as installing the firewall, there are many other configuration jobs to be done and tested:

• Making the e-mail server accessible from the Internet
  
• Domain Name System (DNS) issues
  
• moving server machines to the firewall's DMZ (demilitarized zone)
  
• configuring Microsoft Windows Networking and WINS servers, to operate over a routed network, especially if you are using VPN
  

As part of our installation work we familiarize you with the management of the new network components so that you can easily handle the day-to-day running of your network.

Network consultancy
If you are having performance or other network problems, our engineers can work with you on-site to explore your network, analyze what's happening and decide how to fix the problems.
If you want to re-build or extend your network, in conjunction with you we can design a resilient network that performs well and is easy to manage.

Training courses
We offer four courses which are run on your site. You can customize the courses by choosing from what is in effect a "menu" of our standard material

Training course: Using packet sniffers and protocol analyzers (two days)
This training course covers the following tools:

• the tcpdump packet sniffer
  
• the ethereal protocol analyzer
  
• the Windows Network Monitor protocol analyzer (standard version and extended SMS version)
  and shows how to install and use each one. Practical labs in the course show you how to:
  
• select only the packets you are interested in
  
• drill down into the data you have captured
  
• use the traces to investigate network problems and find bugs in software implementations of the TCP/IP protocols
  
• convert between different data capture formats
  

Training course: SonicWALL firewall installation and management (three days)

• basic SonicWALL concepts
  
• building a test network
  
• standard mode installation
  
• network address translation mode (NAT) installation
  
• allow/deny specific types of traffic
  
• installing site-to-site VPN
  
• installing dial-up client VPN
  
• debugging your setup
• day-to-day management

Training course: Managing and understanding your Internet and TCP/IP network (three to five days)

• TCP/IP routing made simple
  
• IP addressing and the magic subnet mask. Common netmask problems
  
• how your computers find one another - ARP and RARP
  
• centralized configuration with DHCP. BOOTP compatibility
  
• e-mail send/receive with SMTP
  
• e-mail collection with POP3
  
• DNS (domain name service) - how your domain name is translated to a numeric Internet address
  
• HTTP and other protocols
  
• security - firewalls and packet filtering
  
• diagnostic techniques
  

Training course: Integrating Microsoft Windows Networking into a TCP/IP network (three days)

• how Windows Networking differs from other TCP/IP protocols
  
• NetBIOS name resolution; broadcasts; WINS; Active Directory; DNS
  
• authentication and NT domains
  
• NetBIOS browsing - how Network Neighborhood works
  
• tips and tricks for using Windows Networking
  
• troubleshooting Windows Network with Windows Network Monitor and other protocol analyzers
  

Penetration and vulnerability testing

Penetration testing
We partner with one of Europe's top testing companies to provide on a regular (Monthly, Quarterly or Once-off) basis, a thorough testing of the security configurations and effectiveness of your Internet gateway security installation - by probing remotely from the external Internet, in the same manner as any potential intruder.

The testing searches for security vulnerabilities that can be practically identified, including most recent at time of test.
The testing does not require access to the company network, servers, or to privileged information such as computer account/password data - it is based on the 'black-box' approach. The testing is "non-exploitative", i.e. security holes are identified and reported to you, but they are not exploited. There is no attempt to 'break-in' to any systems, and no on-site data files or hard disks will be directly written to.
You receive a written report, containing:

• management overview
  
• summary of the problems discovered sorted by severity
  
• technical details of each issue complete with outline associated recommendations
  
• full listing of the actual tests results tables
  
• notes on the scope and limitations of tests
  

A debriefing session by telephone can also be arranged if required, to give you any advice or clarification you need.

SonicWALL Vulnerability Scanning Service
SonicWALL Vulnerability Scanning Service is an automated, subscription-based security vulnerability assessment service that provides a "hacker's eye view" of a network perimeter, including public servers, routers and gateways, and remote ends of VPN connections. Using an Web-based interface, this service generates detailed reports of security weaknesses and provides administrators with in-depth guidance on how to address the risks.
