1.2 How GFI LanGuard works
Figure 1: How GFI LanGuard works
Upon installation, GFI LanGuard operates in two stages:
First it determines the machines that are reachable. It also tries to collect information sets from the target machines as part of its Network Discovery operations, using a subset of SMB, NETBIOS, and ICMP protocols. Supported targets include the localhost, IP, computer name, computers list,
IP range, whole domain/workgroup and/or organizational unit.
Second, once the targets are identified, GFI LanGuard performs a deep scan to enumerate all the information related to the target computer. GFI LanGuard uses a variety of techniques to gain access to this information ranging from file and folder property checks, registry checks, WMI commands, SMB commands as well as port scan checks (TCP/UDP) and more.
1.3 How GFI LanGuard Agents work
GFI LanGuard can be configured to automatically discover and deploy agents on new computers.
Agents minimize network bandwidth utilization. This is because in Agent-less mode, the GFI LanGuard server component performs audits over the network; while in Agent mode, audits are done using the scan target's resources and only a result XML file is transferred over the network.
Agents send scan data to GFI LanGuard through TCP port 1070. This port is opened by default when installing GFI LanGuard. Agents do not consume resources of the scan target's machine unless it is performing a scan or remediation operations. If an Agent becomes unresponsive for 60 days, it is automatically uninstalled from the target machine.
GFI LanGuard 1 Introduction | 5
Note
By default, Agents auto-uninstall after 60 days. To customize the timeframe, go to
Configuration tab > Agents Management and from the right pane, click Agents Settings.
Specify the number of days in the General tab of the Agents Settings dialog.
Note
Agents can only be installed on computers running a Microsoft Windows operating system and they require approximately 25 MB of memory and 350 MB of hard disc space.
1.4 How GFI LanGuard Relay Agents work
GFI LanGuard enables you to configure any machine with a GFI LanGuard Agent installed on it, to act as a GFI LanGuard server. These Agents are called Relay Agents. Relay Agents reduce the load from the GFI LanGuard server component. Computers configured as relay agents download patches and definitions directly from the GFI LanGuard server and forward them to client computers just as if it were the server component.
1.5 GFI LanGuard Components
This section provides you with information about components that are installed by default, when you install GFI LanGuard. Once you install the product, you can manage patch management and remediation tasks from the Management Console. The Management Console is also referred to as the
Server component of GFI LanGuard, as described in the table below:

2 Installing GFI LanGuard
This chapter guides you in selecting the most appropriate deployment solution that caters to your requirements as well as provides you with information about how to successfully deploy a fully functional instance of GFI LanGuard.
Topics in this chapter:
2.3 Upgrading from previous versions
2.1 Deployment scenarios
GFI LanGuard can be installed on any machine which meets the minimum system requirements. Use the information in this section to determine whether you want to monitor a pool of Agent-less, Agentbased or a mix of both, depending on the:
Number of computers and devices you want to monitor
Traffic load on your network during normal operation time.
The following sections provide you with information about different deployment scenarios supported by GFI LanGuard:
Deploying GFI LanGuard in mixed mode
Deploying GFI LanGuard using Relay Agents
Deploying GFI LanGuard in Agent-less mode
2.1.1 Deploying GFI LanGuard in mixed mode
GFI LanGuard can be configured to deploy agents automatically on newly discovered machines or on manually selected computers. Agents enable data processing and auditing to be done on target machines; once an audit is finished, the result is transferred to GFI LanGuard through an XML file.
Agent-based scans:
Have better performance because the load is distributed across client machines.
Can work on low bandwidth environments because the communication between the server and agents is reduced.
Are suitable for laptops. Computers will be scanned even if the computer is not connected to the company network.
Are more accurate than manual scans, agents can access more information on the local host.
The following screenshot shows how GFI LanGuard can be deployed using agents on a Local Area
Network (LAN):
GFI LanGuard 2 Installing GFI LanGuard | 7
Figure 2: Agent/Mixed Mode
2.1.2 Deploying GFI LanGuard using Relay Agents
Relay agents are used to reduce the load from the GFI LanGuard server. Computers configured as relay agents will download patches and definitions directly from the GFI LanGuard server and will forward them to client computers. The main advantages of using relay agents are:
Save Network Bandwidth in local or geographically distributed networks. If a relay agent is configured on each site, a patch is only downloaded once and distributed to clients
Load is removed from the GFI LanGuard server component and distributed amongst relay agents
Since computers are managed from multiple relay agents, it increases the number of devices that can be protected simultaneously.
In a network, computers can be grouped and each group can be assigned to a relay agent as shown below.
GFI LanGuard 2 Installing GFI LanGuard | 8
Figure 3: Relay Agent Mode
Note
For more information refer to Configuring Relay Agents from the Administrator Guide.
2.1.3 Deploying GFI LanGuard in Agent-less mode
Agent-less auditing is started from the GFI LanGuard management console. GFI LanGuard creates a remote session with the specified scan targets and audits them over the network. On completion, the results are imported into the results database and the remote session ends.
You can audit single computers, a range of specific computers and an entire domain/workgroup.
GFI LanGuard 2 Installing GFI LanGuard | 9
Note
Scans in Agent-less mode use the resources of the machine where GFI LanGuard is installed and utilize more network bandwidth since auditing is done remotely. When you have a large network of scan targets, this mode can drastically decrease GFI LanGuard's performance and affects network speed. In larger networks, deploy Agents/Relay
Agents to balance the load appropriately.
Figure 4: Agent-Less Mode
