As an Information Technology manager who is in charge of the availability, the confidentiality, and the integrity of your small business information system – you should build a high performance and secure network infrastructure. To build a secure network infrastructure you should have a strong security protection in the entry point of the internet by implementing the UTM appliance.
UTM ( Unified Threat Management) appliance is a very essential device in protecting your network environment against any types of emerging internet threats which always evolve to get smarter in penetrating your system vulnerabilities which cannot be just blocked by layer-2 and layer-3 devices such as traditional router / firewall. Your system must be able to scan deep up to the application layer.
The other important system you need to have for your small business network infrastructure is the capability of creating the secure tunnels for remote sites or travelling users to your internal network through the internet as if they work locally in the office. With the limitation of the personnel experts in networking and security, you have lots of works to do. But with all-in-one UTM security appliance you can build a secure small business network easily. Consider D-Link NetDefend DFL-860 – a single solution for UTM and VPN firewall appliance.
