Firewall
Installation and Maintenance
Overview
The threat to corporate data posed by malicious attack from the
internet has never been greater and it is essential that every network
is protected by a reliable firewall. ITSP specialise in selecting and
installing high quality internet firewalls.
Installation Planning
During an initial planning meeting we will review and discuss your specific
security requirements. This will include:
- The current structure of the network
- Applications in use
- Special user requirements
- Remote access requirements
- Existing security policies
Firewall Installation and Configuration
Once we have selected the appropriate firewall for your corporate network,
the installation and configuration phase can begin.
During the configuration stage we will:
- Configure the firewall environmental settings specific to your location.
- Ensure the most current firmware release is loaded.
- Define network settings for the LAN, WAN and DMZ port.
- Implement network access services and filters.
- Enable user management, encryption and event logging.
- Test filtering functionality based on your security requirements.
- Activate / Deactivate features required on the firewall.
- Perform a backup of the final firewall configuration and firmware.
Firewall Testing
After the firewall has been installed and tested for connectivity, we
will begin an external security assessment of the firewall. During this
assessment we will:
- Scan the firewall for port openings (and closures) determined during
the initial meeting.
- Test remote management functionality (if required).
- Ensure all requirements specified during the installation planning
have been met.
Note: installation does not cover configuring equipment other than the
firewall. Configuration services for other equipment can be added by calling
your sales representative.
Ongoing Maintenance
From time to time it will be necessary to reconfigure the firewall
to enable new services or to prevent new threats. In most cases this can
be done remotely and ITSP offer a remote management and monitoring service.
This service ensures your firewall is kept up to date with the latest
firmware updates and security patches.
If your firewall supports VPN technology we also offer management of
the VPN accounts and security.
