Windows-based Server
For protection of Windows-based servers hosting information on the Internet, an extranet, or an intranet, VisNetic Firewall for Servers provides packet-level firewall protection. Recognizing that servers must be accessible to those with proper credentials, and perhaps open to the public anonymously, VisNetic Firewall allows legitimate requests through the firewall while denying access to packets that do not meet the rule-set. Rules within VisNetic Firewall determine whether a packet is allowed or blocked dependent upon parameters such as source and destination IP address, source and destination port, direction of traffic (i.e. inbound and/or outbound) and protocol. Incorporating all of the features of the workstation version, VisNetic Firewall for Servers also includes extended features required by a server such as, Real-Time Activity Viewing, and Selective Control of Other IP Protocols. With the option of real-time viewing of the firewall, the Administrator can actively oversee the firewall and address any issue that might take place while an attack is occurring. VisNetic Firewall for Servers supplies a strong defense mechanism for host computers against data intrusion, attack, theft or damage. The configuration is protected by password security, further protecting the settings of the firewall from tampering. If under attack and specific rules are hit, an Email Notification can be sent to the Administrator's specified email address via a text message. VisNetic Firewall for Servers may also be configured to filter protocols other than IP protocols selectively. Examples of other protocols that VisNetic Firewall will filter include IGMP and GRE. The benefit of blocking these protocols independently, rather than globally, is that selective filtering can take place. As an example, GRE is a protocol used for many VPN implementations and is often ignored by a firewall as trusted traffic; whereas IGMP is a protocol of choice for some attacks. With this feature, an Administrator may allow GRE through the VPN, while blocking IGMP.
