General Technical Specifications
|
The Firewall operates at several layers:
|
Physical Layer
|
Separate network segments and inter-segment routing
|
|
IP Layer
|
Filtering by source/destination and protocol
|
|
Connection Layer
|
Connection tracking and filtering by connection
|
|
Protocol Layer
|
Specific filters for specific protocols
|
Standard firewalls will usually reject unauthorized traffic. Unfortunately, this gives out information to hackers on what is actually protected (as opposed to what is not available).The Network-Box is configurable to silently drop traffic (behaving as a "black hole" - sucking in data without letting anything escape), without giving out any information to hackers who can make use of this information.
NAT (Network Address Translation) is available on all network ports. The Network-Box needs just one single fixed network address, and can share that address amongst all the workstations and servers.
Network call Forwarding and Redirection is available on all network ports. The Network-Box can dynamically forward and redirect calls around the network (including load-balancing incoming calls, or forward calls to servers in the DMZ/LAN).
The firewall is fully configurable and is configured according to each individual company's specific requirements.
All incoming connections can be checked and filtered, according to firewall policy, according to any of the four supported levels of protection.
Outbound connections can also be checked and filtered, according to firewall policy. This can effectively block Trojans and other virus problems, as well as enforce company policies.
Includes a state-of-the-art anti-virus engine. Includes both static signature detection, and dynamic heuristic techniques. Virus signatures are updated in real-time.
Includes a security-hardened SMTP email server. All incoming and outgoing SMTP email is intercepted and handled by this highly-secure server. Mail is scanned and checked for:
- Conformance to acceptable Internet standards
- Anti-relaying - stops Spammers using your server to send mail
- Source blocking - can stop specific email sources
- Anti-Spam-lists - uses Real-time-Black-Lists to reduce Spam
- Anti-Spam-rules - uses heuristic engine to reduce Spam
- Anti-virus - uses anti-virus engine to block viruses in email
- Company Policy - enforces company policy on attachments and limits
- Large-size emails scanning - no specific limits on maximum size of emails or attachments

POP3 and IMAP4 accounts are fully protected by the Network Box solution as soon as they are activated on the LAN. That is it - no setup required. Most systems cannot offer this type of protection at all. Automatic POP3 and IMAP4 email protection also allows sites which do not host their own email systems, to be protected by the Network Box. The outsourcing of email management is common, yet many traditional anti-virus email gateways cannot work with such a configuration, as they only support the SMTP protocol directly.
