Firewall Solutions Netgear FVS318G PROSAFE

Netgear FVS318G PROSAFE one of firewall solutions in protecting your organization against any threats

The NETGEAR ProSafe 8-port Gigabit VPN Firewall is designed for small to medium offices providing secure IPSec site-to-site secure tunneling as well as secure tunneling for remote users. It becomes one of firewall solutions for small businesses with true firewall including customizable rules, manageable via SNMP, ideal solution for any types of internet threats. It provides DoS attack protection, Stateful Packet Inspection (SPI), URL keyword filtering, logging, reporting, and real-time alerts.

Why You Need Firewall

In large network environments, the organizations develop their own security policy including firewalls security standards they need to implement. This is to ensure that internal business assets are protected with a suitably supported and configured firewall. The main function of a firewall is to provide a secure connection between trusted and un-trusted networks. This may also consist of a perimeter router used in conjunction with an external facing firewall and configured security policy. An external public (Internet) connection requires a proven enterprise-based and robust secure firewall which can defend against the variety of Internet based security attacks.

SPI (Stateful Packet Inspection)

A dedicated, system hardened firewall must support the ability to screen packets at any level of the OSI network model. Firewall from most mature firewall products use a method known as “Stateful Inspection” (Dynamic Packet Filtering), which provides the ability to look deep into a packet before the packet is allowed through the firewall. Less secure firewall solutions-like systems may use basic packet filtering (layer-3) or a proxy based system, all of which are susceptible to common security hacking techniques and their use within the corporate must be avoided.

Click for spec details

Implementing firewall solutions in the organizations should choose the firewall that supports the NAT feature in order to hide your internal network from the public network (aka internet). This provides the ability to mask the internal networks from the outside-world. Microsoft’s ISA server uses LAT (Local Address Table) which ensures that internal addresses are not exposed to the Internet. Netgear FVS318G supports both NAT and SPI.

Threats Protection

Firewalls must also be able to defend against common Internet attacks. These include; anti-spoofing (LAN attack), SYN attacks (TCP 3-way handshake), ping-of-death, WinNuke, UDP bombers and session hijacking. These attacks target known weaknesses in the network and host sub-systems found in most corporate environments.

Firewall solutions must also support detailed logging as well as alert notification. This enables detailed analysis and ensures that only authorized traffic is traversing the corporate firewall system. Other features such as Active-X, Java, URL blocking and virus scanning may be required in environments where content filtering is a concern.

Netgear FVS318G VPN firewall includes the denial-of-service (DoS) protection, stateful packet inspection (SPI), URL keyword filtering, logging, reporting, and real-time alerts.

Firewall solutions should also support industry standard VPN (Virtual Private Networks) encryption options. Proprietary and non-standards based encryption methods should be avoided, due to the lack of industry scrutiny and potential security holes.

Firewall solutions must be readily manageable and allow for access rules to be routinely modified and verified. The use of Intrusion Detection Systems (IDS) may also be considered and will offer further intelligent security against DDOS (Dynamic Denial Of Service) attacks.

Best Practices in Industry

Best practices for firewall solutions implemented in industrial should comply to the following minimum standards:

1. Firewall must be dedicated system
2. Firewall must be hardened system
3. A minimum of three or more interfaces
4. A firewall must support NAT and dynamic filtering with screening capabilities at the application layer (OSI-layer7) to provide optimal network security
5. Firewall must provide management based security policies and provide the ability to define sequential (ordered or best fit) rules that either permit or deny specific traffic.
6. By default must be configured to “deny all”
7. Capable of providing logging and alerts
8. Capable of protecting any types of threats
9. Must support strong VPN technology including IPSec and L2TP and iVPN compatible

Netgear FVS318G VPN firewall is a good solution for small to medium offices to provide site-to-site VPN connection and strong secure protection against any internet threats.
