1.1. Features

A Clavister NetShield Firewall running cOS Stream provides vital network security functions while providing high throughput performance by fully utilizing the parallel processing advantages of multi-core hardware platforms.

The firewall also provides seamless integration of all its subsystems, in-depth administrative control of functionality, as well as exposing a minimal attack surface which helps negate the risk from security attacks.

Configuration Objects

From the administrator's perspective the conceptual approach is to visualize operations through a set of logical building blocks or configuration objects. Combining different objects allows configuration in an almost limitless number of different ways. This granular control allows the administrator to meet the requirements of the most demanding network security scenarios.

Key Features

The list below presents the key features of cOS Stream's extensive feature set:

IP Routing
cOS Stream provides a variety of options for IP routing including static routing.
Firewalling Policies
cOS Stream provides stateful inspection-based firewalling for a wide range of protocols such as TCP, UDP and ICMP. The administrator can define detailed firewalling policies based on source/destination network/interface, protocol and ports.
VPN
cOS Stream supports IPsec based VPNs and can provide individual security policies for each VPN tunnel.
High Availability

High Availability (HA) is supported through automatic fault-tolerant failover to a secondary Clavister NetShield Firewall should a failure be detected. Two firewalls operate together in an HA cluster, with one being active while the other is passive and constantly mirroring the state of the active unit.

This feature is described in more detail in Chapter 22, High Availability.
