Firewalls

ACM provides the latest technology from Sonicwall, leader in network firewall systems. The system is designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both to prevent unauthorized individuals to access your data.

 

A firewall is an integrated collection of security measures designed to prevent unauthorized electronic access to a networked computer system. It also allows for sets of devices or set of devices configured to permit, deny, encrypt, decrypt, or proxy all computer traffic between different security domains based upon a set of rules and other criteria.

 

Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.

The SonicWALL ® TZ Series is the ideal total security platform for home, small and remote/branch offices, providing a compelling blend of ease-of-use for basic networks and unsurpassed flexibility for more complex networks.

 

Malicious attacks can penetrate outdated stateful packet inspection firewalls. The TZ Series integrates a deep packet inspection firewall, 802.11b/g secure wireless, gateway anti-virus, anti-spyware, intrusion prevention, content filtering, failover/failback technologies and IPSec VPN capabilities into a cost-effective solution, and scales to protect your investment as your organization grows. 

 

VPN 


A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) as opposed to running across a single private network. The link-layer protocols of the virtual network are said to be tunneled through the larger network.

 

One common application is secure communications through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. VPNs, for example, can be used to separate the traffic of different user communities over an underlying network with strong security features.
