Global Technology Associates' primary corporate mission is to provide solid security solutions. In 1996 GTA introduced the GNAT Box Firewall which has continually evolved into its current product line of Firewall Unified Threat Management Appliances. The underlying technology for each Firewall UTM Appliance is GTA's proprietary operating system, GB-OS.
GB-OS is Global Technology Associates' dedicated, feature rich, firewall operating system - providing comprehensive network security and total perimeter threat management in a single system. GB-OS reduces the complexity of maintaining firewall security with innovative features and a wide array of powerful, customizable configuration options. The customizable options allow organizations to fine-tune GB-OS to meet their needs and with consistent features across GTA's entire product line, GB-OS is able to grow with an organization.
Intuitive, Flexible Configuration
Assisting users via a guided walk through for a variety of standard configuration tasks, GB-OS' wizard section supplies all levels of users with the tools needed to successfully configure a GTA firewall. The Basic Setup Wizard guides novice users through what can be a complex and intimidating task of standard firewall configuration while the VPN Setup Wizard supplements the guided directions with graphical reinforcement of completed tasks - providing the user with a better understanding of the VPN creation process. The IPS Setup Wizard also provides an intuitive interface to guide users through the initial setup of an intrusion prevention system.
Automatically generating basic policies for implementing many firewall or networking features, GB-OS reduces the complexity of utilizing these features on the GTA firewall. With the basic policies generated automatically, administrators can focus on customizing the default policies to match their network and security implementation. Automatic policy generation is available for many features on GTA firewalls including VPN, SNMP, DNS and NTP services.
Simple, flexible security policies allow network administrators to match the firewall's configuration to the network it protects. Administrators are able to create objects to predefine network addresses, VPN settings, service groups and time groups. With country blocking, administrators can allow or deny traffic based upon IP address country codes. And with object encapsulation, one-click access to new configuration screens, new objects can be created without exiting the configuration section.
Furthermore, GB-OS eliminates the worry about network stability when making configuration changes or version upgrades. With Live and Test modes, administrators can reduce downtime and errors when modifying a system's configuration. During version upgrades, GB-OS maintains an easily accessible copy of the previous runtime configuration in non-volatile static memory. These redundant runtimes provide a fail safe environment to edit configurations and upgrade. And with automatic updates, GB-OS is assured to always be running the latest version, protecting networks from the latest Internet-based attacks with up-to-the-minute features and enhancements.
GB-OS also includes automatic backup options, ensuring safe and reliable access to vital firewall configurations. By enabling automatic backup, a backup file is saved every time a change is made and saved during LIve mode. These backups can be emailed, saved to a USB device, or saved to a remotely secure cloud storage location. The backups can then be downloaded and imported back into the firewall from either the USB device or cloud storage.
Dynamic Gateway Architecture
GB-OS' unique Dynamic Gateway Architecture provides traffic shaping, load sharing, dynamic routing and gateway failover for flexible traffic management. Traffic shaping is essential for network administers to optimize network usage. Choose from a variety of routing protocols including RIP, BGP and OSPF as well as static routing and policy-based routing. The many customizable routing options provided by GB-OS ensure easy implementation into most network environments.
Gateway failover adds an extra layer of redundancy to a network setup by allowing for mulitple external gateways. GB-OS will seamlessly redirect all outbound traffic to an alternate gateway should the primary fail. GB-OS also supports several types of link aggregation (failover, LACP- Link Aggregation Control Protocol, Load Balance, and Round Robin), providing system administrators with the tools to increase bandwidth speed and network failover. Increased throughput and redundant connectivity ensure the reliability of network uptime.
Comprehensive Unified Threat Management Protection
With GB-OS' robust unified threat management features, administrators can effectively lock down their network while protecting resources from dynamic threats. Powerful unified threat management features include an Intrusion Prevention System (IPS), GTA's Mail Proxy with Anti-Spam and Anti-Virus options and Content Filtering with an additional Web Filtering option.
GB-OS includes an Intrusion Prevention System which carefully analyzes traffic and automatically blocks attacks before reaching the network. By comparing data packets against over 4000 signatures, GB-OS is able to protect networks from a variety of exploits including Web attacks, telnet, RPC, database, NetBIOS, multimedia, email, FTP, network services, DoS/DDos, peer to peer and backdoor attacks. Users will be able to selectively activate IPS rules on their system and updated signatures are automatically delivered to the firewall.
Optional mail and web content offerings further protect the network. The Mail Proxy Anti-Virus option provides real-time virus and malware scanning of email against a database of nearly 100,000 virus definitions. The Mail Proxy Anti-Spam subscription option, powered by MailShell’s multi-level anti-spam technology, offers customizable spam blocking and filtering for a system’s email proxy. Finally, the Web Filtering subscription option allows organizations to increase productivity and reduce liability by limiting access to unproductive or inappropriate web sites based on over 70 category ratings.
IPv6 is an internet protocol, the future of IP addresses that will replace the current IPv4 addresses. IPv6 addresses are 128-bit numbers, divided into eight, 16-bit hexadecimal blocks separated by colons. IPv4 addresses are 32-bit numbers with about 4.3 billion possible addresses. In contrast, IPv6 addresses are 128-bit numbers with approximately 340 undecillion (1036) possible addresses.
As scarcity of IPv4 address continues to increase, it is important to prepare for the future of IPv6 addresses. GB-OS allows organizations to prepare for and deploy IPv6 to ensure business continuity and growth, while still using IPv4. IPv6 configuration support includes statically assigned IP addresses for IPv6, DHCPv6, Stateless Address Auto configuration (SLAAC), Dual Stack (IPv4 and IPv6) addresses, IPv4 and IPv6 VLAN interfaces, IPv4 and IPv6 Link Aggregation, IPv4 HA Interfaces and IPv4 Bridge Mode. With each update and software release, GTA continues to expand IPv6 support for various features, services and configuration options.
VPN Features including Remote Access
Integrated industry standard IPSec virtual private networking for both site-to-site installations and remote mobile users means that secure remote access can be a reality for even the smallest organization. GB-OS contains comprehensive VPN features such as certificate support, NAT through VPN, VPN keep alives, and VPN failover along with several options for remote access.
VPN connections can be authenticated utilizing GBAuth, Single Sign-on, or certificates - providing an additional layer of authentication control. With VPN keep alives consistent, continuous connections are ensured even during periods of no activity. This establishes a stable VPN connection in case of Internet network disruption or periods of no data packet transmissions. GB-OS also provides business continuity with VPN failover. Continuous uptime is provided through automatic backup tunnels for every active tunnel. Should one tunnel fail, business activities will be able to proceed uninterrupted without compromising network security.
With GB-OS, several remote access options are available through the GTA Mobile IPSec VPN Client, PPTP, L2TP, SSL Browser and SSL Client. Easy to install and setup, these options allow remote workers to securely access protected networks. Users are seamlessly connected to the network, allowing access to files, applications and intranets. Via GB-OS' Unified Threat Management protection, user authentication and threat detection occur at the gateway, protecting against unauthorized access, data loss and malicious threats such as viruses, worms and spyware. GTA's remote access options are flexible and guarantee safe and secure network access from virtually any location and device.
