Firewall Internet Security - The Basics of a Firewall

Firewalls

Enterprise companies today employ firewalls that do stateful inspection of sessions between external and internal hosts and devices. Cisco employs a patented ASA algorithm that utilizes source IP address, destination IP address, TCP sequence numbers, port numbers and TCP flags to examine and prevent unauthorized sessions. The firewall is configured with conduit statements to filter traffic by examining source/destination IP addresses, application port and protocol port before making a decision whether to permit or deny a session or specific traffic.

Firewalls are implemented at the company demilitarized zone (DMZ) which is located between the external network and the company internal network. Static routing is typically configured at the DMZ between firewalls and internal/external routers for improved security. This is to have greater control over route propagation than would be available with dynamic routing protocols such as RIP and EIGRP. Internal and DMZ (Public) servers would be configured to use the firewall as their default route to forward Internet traffic. If an internal router were available, servers would use that as their default gateway to forward Internet traffic.

The external router broadcasts a default route to the firewall that is used to forward traffic destined for the Internet. A conduit must be configured at the firewall for each protocol type that should be allowed through your firewall. For instance, if your company manages routers and servers across a firewall, you must configure a conduit for SNMP traffic to allow traps through the firewall. The conduit would specify the source address of the router which is sending SNMP traps, the destination address of the network management station that is receiving SNMP traps, and UDP 161 which is the UDP port number for sending SNMP traffic from managed devices to a network management station.

The firewall examines the end to end session connection and does a lookup of its conduit table to determine if a particular source address, destination address, protocol port or application port is allowed through. The packet is discarded or allowed through on to the company network (inside) or Internet depending upon the conduit statements configured.

TACACS Server

This is a TCP service running on a designated Unix server that authenticates employees attempting to access a router. The routers must be configured to send a request to the TACACS server when someone attempts to logon to a router. The router prompts the user for a username/password pair and sends that to the TACACS server for authentication. TACACS servers are implemented with VPN services as well to authenticate remote users before allowing that session to continue with network authentication to Windows Server, Unix or Mainframe authentication and authorization.

RADIUS Server

This is a UDP service running on a designated network server that authenticates employees attempting to access a router. The routers must be configured to send a request to the RADIUS server when someone attempts to logon to a router. The router prompts the user for a username/password pair and sends that to the RADIUS server for authentication. RADIUS servers are implemented with VPN services as well to authenticate remote users before allowing that session to continue with network authentication to Windows Server, Unix or Mainframe authentication and authorization.

CISCO 8x10/100 VPN Router $309 Die innovative Netzwerklösung für geteilten Internet-Zugang wurde speziell für die Anforderungen kleiner Unternehmen entwickelt.Wie jeder herkömmliche Router sorgt auch der RV082 von Cisco als Herzstück eines Small Office-Netzwerkes dafür, dass mehrere Rechner eine Internet-Verbindung nutzen können. Die Besonderheit des RV082 aber liegt im einzigartigen zweiten Internet-Port. Damit lässt sich eine weitere Online-Verbindung unterhalten - entweder als Back-up oder mit der simultanen Verwendung beider Eingänge. In diesem Fall steuert der Router die beiden Ports je nach Bedarf so aus, dass jederzeit ein Maximum an Bandbreite für Up- und Downstreams zur Verfügung steht.Weiteres Feature des Cisco VPN-Routers ist der eingebaute 8-Port Full Duplex 10/100 Ethernet-Switch, mit dem sich acht PCs direkt anschliessen lassen. Fügt man zusätzliche Switches hinzu, lässt sich ein Office-Netzwerk problemlos erweitern.Einen grossen Nutzen für kleine oder mittelständische Unternehmen bietet der Cisco RV082 durch seine VPN-Funktionalität (Virtual Private Network). Über das Internet werden verschlüsselte Tunnels erzeugt, durch die sich Geschäftsreisende und Aussendienstmitarbeiter sicher ins Firmennetzwerk einloggen können - wo auch immer sie sich gerade aufhalten. Der Zugriff auf Daten, eMails oder einem Intranet durch einen VPN-Tunnel ist so leicht und sicher, als befände man sich im Nebenraum.Der 10/100 8-Port-VPN-Router kann auch als DHCP-Server fungieren und enthält eine Stateful Packet Inspection (SPI)-Firewall zum Schutz vor Eindringlingen aus dem Web und sonstigen Attacken. Konfiguriert werden kann er so, dass nur ausgewählte User Zugang zum Internet erhalten (IP-Adressen-filter). Wie bei allen Cisco-Routern erfolgt die Konfiguration einfach und schnell durch den Webbrowser.
