Security: Firewall
Function & Value
A firewall is the gateway into your network, controlling all inbound and outbound access to and from the servers and PCs you control. A firewall provides the ability to securely access PCs and servers remotely, which is good for telecommuting employees as well as rapid response from your IT firm. Firewalls also often include anti-malware protection, anti-spam abilities (if you host your own email), Internet content filtering and broadcasting for wireless Internet access.
A firewall is the most important piece of your business’ security technology. Underpowered firewalls or wrong configurations can leave your network and data exposed. Here are the common problems we see with firewall use, as well as best practices.
Common Problems
(1) Using a non-business class “all-in-one”. These devices are cheaper, but don’t offer the same tools for remote access and security. They also have limited “throughput”, which means when several people or devices are accessing your server(s) or network at the same time, you get traffic jams.
(2) Failure to secure wireless access. Providing wireless access is great. Providing wireless access to everyone is not as great. Providing wireless access into your private network to everyone that is not great at all. It’s bad.
Best Practices
(1) Use a business class firewall. This gives you access not only to solid remote access abilities (both for IT and remote employees), but strong security, anti-malware abilities and content filtering.
(2) Make sure your wireless access is protected. In tech language, “WPA2 Personal” is the safest access protection for a small business. As always, very secure passwords are critical. Many firewalls have the ability to provide both public and private wireless, giving guests wireless Internet access and staff wireless network access.
