Information is an asset which, like other important business assets, has value to the organization and consequently needs to be suitably protected. In enterprise class businesses, they have Information Technology (IT) department that is in charge in providing the availability, integrity, and the confidentiality of the business resources (the information asset). One of the main tasks in IT department is protecting the internal network against any types of network and internet threats. Hundreds of new viruses and worms are introduced into the wild internet every week. In network businesses, you should have a well managed anti-virus infrastructure centrally to prevent the virus outbreak to spread into the private network. Spam is annoying, phishing and virus-laden messages from inbound SMTP-based emails must be blocked before they reach your network. You need to deploy such kind of anti-spam appliance. Hacker techniques are evolving gradually, therefore deployment such firewall with Intrusion detection system is essentials to help your system detect any false positive packets and drop them before they reach the internal network. As a security best practice, any connection to the network that come from the internet must be done in a secure way. Deployment of virtual private network infrastructure is a must to allow mobile users or travelling users create secure tunneling to the private network. With the VPN infrastructure, you can connect the branch offices in secure way using L2TP / IPSec VPN. And tele-workers can easily and securely access the business network via public internet. To provide business continuity in communication system, any single failure of the system element must be eliminated. System redundancy in communication system must be developed to allow a load balancing and failover / failback system. We can see that those systems are very complicated for small to medium businesses and are very expensive deployment with several experts in their fields.
