This chapter contains the following topics: • Before you begin • How this guide is organized Before you begin Before you begin using this guide, please ensure that: • You have administrative access to the web-based manager and/or CLI. • The FortiGate unit is integrated into your network. • The operation mode has been configured. • The system time, DNS settings, administrator password, and network interfaces have been configured. • Firmware, FortiGuard Antivirus and FortiGuard Antispam updates are completed. • Any third-party software or servers have been configured using their documentation. While using the instructions in this guide, note that administrators are assumed to be super_admin administrators unless otherwise specified. Some restrictions will apply to other administrators. How this guide is organized This FortiOS Handbook chapter contains the following sections: Managing “bring your own device” describes device monitoring, devices, device groups, and device policies. The administrator can monitor all types of devices and control their access to network resources. Endpoint Protection describes how you can enforce the use of FortiClient Endpoint Control and apply an endpoint profile to users’ devices. Endpoint profiles include real-time antivirus protection, application control, web category filtering, and VPN provisioning. Vulnerability Scan describes how perform network vulnerability scanning to look for security weaknesses in your servers and workstations. Fortinet Technologies Inc. Page 4 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Managing “bring your own device” FortiOS can control network access for different types of personal mobile devices that your employees bring onto your premises. You can: • identify and monitor the types of devices connecting to your networks, wireless or wired • use MAC address based access control to allow or deny individual devices • create policies based on device type • enforce endpoint control on devices that can run FortiClient Endpoint Control software Device monitoring The FortiGate unit can monitor your networks and gather information about the devices operating on those networks. Collected information includes: • MAC address • IP address • operating system • hostname • user name • how long ago the device was detected and on which FortiGate interface You can go to User & Device > Device > Device Definitions to view this information. Device monitoring is enabled separately on each interface. Device detection is intended for devices directly connected to your LAN ports. If enabled on a WAN port, device detection may be unable to determine some devices’ operating system. Page 5 To configure device monitoring 1. Go to System > Network > Interfaces. 2. Edit the interface that you want to monitor devices on. 3. In Device Management, select Detect and Identify Devices. 4. Select OK. 5. Repeat steps 2 through 4 for each interface that will monitor devices. To assign an alias to a detected device or change device information 1. Go to User & Device > Device > Device Definitions. 2. Double-click the device entry or right-click it and select Edit. 3. Enter an Alias such as the user’s name to identify the device. This is step is compulsory. The alias replaces the MAC address in the device list. 4. Change other information as needed. 5. Select OK. To add a device manually 1. Go to User & Device > Device > Device Definitions and select Create New. 2. Enter the following information. • Alias (required) • MAC address • Device Type 3. Optionally, select Custom Groups or enter Comments. 4. Select OK. Device Groups Device Groups are used in device policies to specify which devices match the policy. FortiOS automatically adds detected devices of well-known device types to predefined device groups. You can also create custom device groups so that you can create a different policy for devices that you know than for devices in general. Go to User & Device > Device > Device Groups to view the list of device groups. To view all groups, select Show Empty Groups at the top right of the list. Table 1: Predefined Device Groups Group Devices All All devices. Android Phone All Android-based phones in the Device Visibility database. Android Tablet Tablets running Android OS. BlackBerry Phone All BlackBerry-based phones in the Device Visibility database. BlackBerry PlayBook All BlackBerry PlayBook devices in the Device Visibility database. Collected Emails All devices from which FortiOS has collected a user email address. Fortinet Device FortiGate, FortiManager, FortiAnalyzer, FortiMail, etc. Fortinet Technologies Inc. Page 6 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Table 1: Predefined Device Groups Group Devices Gaming Console All Gaming consoles listed in the Device Visibility database. This includes Xbox, PS2, PS3, Wii, PSP. IP Phone All IP phones. iPad All IOS-based tablets in the Device Visibility database. iPhone All IOS-based phones in the Device Visibility database. Linux PC PCs running a Linux-based OS. Mac Apple Macintosh computers. Media Streaming Media streaming devices such as Apple TV. Router/NAT Device Router. Windows PC PCs running a Windows OS. Windows Phone All Windows OS based phones. Windows Tablet All Windows-based tablets. Other Network Device All other network devices not categorized under any other group. Creating a custom device group In addition to the predefined device groups, you can create custom device groups, where you choose the member devices. For ease of identifying devices, Fortinet recommends that you assign each device an Alias. For previously detected devices, you can edit the existing device definition to assign an alias. For devices that have not yet been detected, you can add a device definition if you know the device’s MAC address. At that time you can also assign an alias for the device. To create a custom device group and add devices to it 1. Go to User & Device > Device > Device Groups and select Create New. 2. Enter a Name for the group, Employees for example. 3. Click in the Members field and click a device to add. Repeat to add other devices. 4. Select OK. The devices are added to the custom device group. Fortinet Technologies Inc. Page 7 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Controlling access with a MAC Address Access Control List A MAC Address Access Control List is best used to handle exceptions. If you want to limit network access to a larger group such as your employees, it is better to create a custom device group and specify that group in your device-based security policies. A MAC Address Access Control List functions as either a list of blocked devices or a list of allowed devices. This is determined by the Unknown MAC Address entry. • By default, unknown MAC addresses are allowed: Action is Assign IP. You add an entry for each MAC address that you want to block and set its Action to Block. • If you want to restrict access to a limited set of devices, you set the Unknown MAC Address entry to Block and add an entry for each allowed MAC address with Action set to Assign IP. To create a MAC Address Access Control List 1. In the SSID or other interface configuration, select Enable DHCP Server. 2. Enter the required Address Range and Netmask. 3. Expand Advanced. 4. In MAC Address Access Control List, select Create New and enter the device’s MAC Address. 5. Select Assign IP to allow the device or Block to block the device and then select OK. 6. Repeat Steps 4 and 5 for each additional MAC address entry. 7. If needed, edit the Unknown MAC Address entry to set the correct Action. Device policies Policies based on device identity enable you to implement policies according to device type. For example: • Gaming consoles cannot connect to the company network or the Internet. • Personal tablet and phone devices can connect to the Internet but not to company servers. • Company-issued laptop computers can connect to the Internet and company servers. Web filtering and antivirus are applied. • Employee laptop computers can connect to the Internet, but web filtering is applied. They can also connect to company networks, but only if FortiClient Endpoint Security is installed to protect against viruses. Figure 1 and Figure 2 show these policies implemented for WiFi to the company network and to the Internet. Fortinet Technologies Inc. Page 8 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Figure 1: Device policies for WiFi access to the company network Figure 2: Device policies for WiFi access to the Internet The next section explains device policy creation in detail. Fortinet Technologies Inc. Page 9 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Creating device policies Device-based security policies are similar to policies based on user identity: • The policy enables traffic to flow from one network interface to another. • NAT can be enabled. • Authentication rules can allow or deny specific devices or device groups. • UTM protection can be applied. To create a device identity policy 1. Go to Policy > Policy > Policy and select Create New. 2. In Policy Subtype, select Device Identity. 3. Choose Incoming Interface, Source Address, and Outgoing Interface as you would for any security policy. 4. Select Enable NAT if appropriate. You are now ready to create authentication rules. To create an authentication rule 1. Select Create New. 2. Enter Destination, Schedule, and Service as you would for any security policy. 3. In Device, select the devices or device groups to which this policy applies. You can select multiple devices or groups. 4. Select Compliant with Endpoint Profile if you want to enforce use of FortiClient Endpoint Security by the client devices. This is available here only if Action is ACCEPT. See “Adding endpoint protection” next. 5. Select either ACCEPT or DENY as the policy Action. 6. Configure UTM Security Profiles as you would for any security policy. 7. Select OK. 8. Select OK again to complete creation of the security policy. Adding endpoint protection Optionally, you can require that users’ devices have FortiClient Endpoint Security software installed. The software provides FortiOS more detailed information about the applications being used. FortiOS pushes a FortiClient profile out to the FortiClient software, configuring network protection such as antivirus, application control, and web category filtering. Devices without an up-to-date installation of FortiClient software are restricted to a captive portal from which the user can download a FortiClient installer. If you have already created an ACCEPT rule for particular device groups, you simply edit this rule and enable Compliant with Endpoint Profile. Then select the device policy option that directs FortiClient-compatible devices to a captive portal. Figure 3: Authentication rule with Endpoint compliance and captive portal enabled For more information, see “Endpoint Protection” on page 12. Fortinet Technologies Inc. Page 10 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Setting Device Policy Options 1. Optionally, enable Attempt to detect all Unknown device types before implicit deny. 2. Redirect all non-compliant/unregistered FortiClient compatible devices to a captive portal enables the captive portal. Select which device platforms to include. 3. Optionally, enable Prompt Email Address Collection Portal for all devices. This requests an email address from the device user. See “Guest access in a retail environment” on page 994. Fortinet Technologies Inc. Page 11 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Endpoint Protection This section describes the Endpoint Protection feature and how to configure it. The following topics are included in this section: • Endpoint Protection overview • Configuration overview • Creating a FortiClient profile • Enabling Endpoint Protection in security policies • Configuring endpoint registration over a VPN • Monitoring endpoints • Modifying the Endpoint Protection replacement messages Endpoint Protection overview Endpoint Protection enforces the use of up-to-date FortiClient Endpoint Security software on endpoints (workstation computers and mobile devices). It pushes a FortiClient profile to the FortiClient application, specifying security settings, including: • Real-time antivirus protection - on or off • FortiClient web category filtering based on web filters defined in a FortiGate web filter profile • FortiClient application control (application firewall) using application sensors defined in the FortiGate application control feature • Endpoint vulnerability scanning daily, weekly, or monthly The FortiClient profile can also specify: • VPN configurations • Uploading of logs to the FortiGate unit hourly or daily • Configuration profile (.mobileconfig file for iOS) • Dashboard banner You enable Endpoint Security in device identity security policies by enabling Compliant with FortiClient Profile. Optionally, the security policy can redirect non-compliant endpoints to a captive portal to download FortiClient software. Otherwise, non-compliant endpoints are blocked. User experience Endpoint Protection applies to users attempting to make a connection that is controlled by a firewall policy that specifies a FortiClient profile. The user of a non-compliant endpoint using a web browser receives a replacement message HTML page from the FortiGate unit. The message explains the non-compliance. Depending on the FortiClient profile, the user may be allowed to continue or is blocked from further access. For information about modifying these replacement pages, see “Modifying the Endpoint Protection replacement messages” on page 19. Page 12 FortiClient non-compliance If the authentication rule in a device identity policy requires endpoint protection, a device without the latest version of FortiClient Endpoint Security installed is denied access. Optionally, the user is redirected to a captive and sees a message like this: Figure 4: Default FortiClient non-compliance message for Windows After installing FortiClient Endpoint Security, the user will receive an invitation to register with the FortiGate unit. If the user accepts the invitation, the FortiClient profile is sent to the device's FortiClient application. Now the user can pass the authentication rule and connect to the network. FortiClient Endpoint Security registered with a FortiGate unit does not need to be separately licensed with FortiGuard. The FortiGate unit can also register endpoints who connect over the Internet through a VPN. The user can accept an invitation to register with the FortiGate unit. See “Configuring endpoint registration over a VPN” on page 18. FortiGate endpoint registration limits To view the number of endpoints that are registered and the total that can be registered, go to System > Dashboard > Status. Under License Information, find FortiClient Software. You will see a line like “Registered/Allowed 4 of 10”. This means that there are four registered endpoints and a total of ten are allowed. When the registration limit is reached, the next FortiClient-compatible device will not be able to register with the FortiGate unit. The user sees a message in FortiClient application about this. The FortiClient profile is not sent to client and the client cannot connect through the FortiGate unit. For all FortiGate models, the maximum number of registered endpoints is ten. For all models except 20C and 40C, you can purchase an endpoint license to increase this capacity: Fortinet Technologies Inc. Page 13 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 To add an endpoint license - web-based manager 1. Go to System > Dashboard > Status. 2. In the License Information widget, under FortiClient Software, select [Enter License], enter the license key, and select OK. Table 2: Maximum registered endpoints with endpoint license Model type Max Registered Endpoints Desktop 200 Rack - 1U 2000 Rack - 2U+ 8000 Configuration overview Endpoint Protection requires that all hosts using the firewall policy have the FortiClient Endpoint Security application installed. Make sure that all hosts affected by this policy are able to install this application. Currently, FortiClient Endpoint Security is available for Microsoft Windows (2000 and later) and Apple Mac OSX only. To set up Endpoint Protection, you need to • Enable Central Management by the FortiGuard Analysis & Management Service if you will use FortiGuard Services to update the FortiClient application or antivirus signatures. You do not need to enter account information. See “Centralized Management” in the System Administration chapter of the FortiOS Handbook. • By default, the FortiGuard service provides the FortiClient installer. If you prefer to host it on your own server, see “Changing the FortiClient installer download location” on page 14. • In Security Profiles, configure application sensors and web filters profiles as needed to monitor or block applications. See the Security Profiles Guide chapter of the FortiOS Handbook.for details. • Create a FortiClient profile or use a predefined profile. See “Creating a FortiClient profile” on page 15. Enable the application sensor and web category filtering profiles that you want to use. • Enable Compliant with FortiClient Profile in the authentication rules of Device Identity security policies that the endpoints will use. • Optionally, configure the FortiGate unit to support endpoint registration by IPsec or SSL VPN. Changing the FortiClient installer download location By default, FortiClient installers are downloaded from the FortiGuard network. You can also host these installers on a server for your users to download. In that case, you must configure FortiOS with this custom download location. For example, to set the download location to a customer web server with address custom.example.com, enter the following command: config endpoint-control settings set download-location custom set download-custom-link "http://custom.example.com" end Fortinet Technologies Inc. Page 14 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Creating a FortiClient profile Each FortiClient profile is assigned to particular device groups, user groups, or individual users. When Compliant with FortiClient Profile is selected in an authentication rule, all users of that rule must have FortiClient Endpoint Security installed. The FortiGate unit pushes the FortiClient profile settings to the FortiClient application on the client. To create a FortiClient profile - web-based manager 1. If you will use the Application Firewall feature, go to Security Profiles > Application Control > Application Sensors to create the Application Sensors that you will need. 2.

Page 17 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Configuring endpoint registration over a VPN FortiGate units can register FortiClient-equipped endpoints over either an interface-based IPsec VPN or a tunnel-mode SSL VPN. After the user authenticates, the FortiGate unit sends the FortiClient application the IP address and port to be used for registration. If the user accepts the FortiGate invitation to register, registration proceeds and the FortiClient profile is downloaded to the client. Users without FortiClient Endpoint Security connecting to the SSL VPN through a browser can be redirected to a captive portal to download and install the FortiClient software. The security policy must enable Redirect all non-compliant/unregistered FortiClient compatible devices to a captive portal, but not select any specific device types. Endpoint registration on an IPsec VPN You can enable endpoint registration when you configure the FortiClient VPN or you can enable it on an existing FortiClient VPN. To enable endpoint registration while configuring the VPN • Enable Allow Endpoint Registration on the Network page of the VPN Wizard when creating the FortiClient VPN. To enable endpoint registration on an existing VPN 1. Go to System > Network > Interfaces and edit the VPN’s tunnel interface. The tunnel is a subinterface of the physical network interface. 2. In Administrative Access, make sure that FCT-Access is enabled. 3. Select OK. Endpoint registration on the SSL VPN To enable endpoint registration on the SSL VPN 1. Go to VPN > SSL > Portal. 2. Make sure Enable Tunnel Mode is enabled. 3. Optionally, enable Include FortiClient Download. Users who access the VPN with a browser will be able to download FortiClient Endpoint Security for their device. 4. Select Apply. 5. Go to VPN > SSL > Config, make sure Allow Endpoint Registration (Tunnel Mode Only) is enabled, then select Apply. This procedure does not include all settings needed to configure a working SSL VPN. Synchronizing endpoint registrations To support roaming users in a network with multiple FortiGate units, you need to configure synchronization of the endpoint registration databases between the units. The registered endpoints are then recognized on all of the FortiGate units. This is configured in the CLI. For Fortinet Technologies Inc. Page 18 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 example, to synchronize this FortiGate unit’s registered endpoint database with another unit named other1 at IP address 172.20.120.4, enter: config endpoint-control forticlient-registration-sync edit other1 set peer-ip 172.20.120.4 end Monitoring endpoints Go to User & Device > Monitor > FortiClient to monitor endpoints. Modifying the Endpoint Protection replacement messages If the security policy has Redirect all non-compliant/unregistered FortiClient compatible devices to a captive portal enabled, users of non-compliant devices are redirected to a captive portal that is defined by the Endpoint NAC Download Portal replacement message. There are different portals for Android, iOS, Mac, Windows, and “other” devices. Optionally, you can modify them. To modify the Endpoint NAC Download Portal 1. Go to System > Config > Replacement Message Group and select Extended View. 2. In the Endpoint Control section select the message that you want to edit. The replacement message and its HTML code appear in a split screen in the lower half of the page. 3. Modify the text as needed and select Save. Fortinet Technologies Inc. Page 19 FortiOS™ Handbook - Managing Devices for FortiOS 5.0 Vulnerability Scan The Network Vulnerability Scan helps you to protect your network assets (servers and workstations) by scanning them for security weaknesses. You can scan on-demand or on a scheduled basis. Results are viewable on the FortiGate unit, but results are also sent to an attached FortiAnalyzer unit. The FortiAnalyzer unit can collect the results of vulnerability scans from multiple FortiGate units at different locations on your network, compiling a comprehensive report about network security. This section describes how to configure a single FortiGate unit for network scanning and how to view the results of the scan. The following topics are included in this section: • Configuring vulnerability scans • Running a vulnerability scan and viewing scan results • Requirements for authenticated scanning and ports scanned Configuring vulnerability scans You can configure the scan schedule and the assets to be scanned. To configure scanning - web-based manager 1. Go to User & Device > Vulnerability Scan > Scan Definition. 2. Beside Schedule select Change to set the scan schedule and mode: Recurrence Select Daily, Weekly, or Monthly and configure the details for the option you have selected. Suspend Scan between Set a time during which the scan should be paused if its running. Vulnerability Scan Mode Quick — check only the most commonly used ports Standard — check the ports used by most known applications Full — check all TCP and UDP ports For a detailed list of the TCP and UDP ports examined by each scan mode, see Table 3 on page 25. 3. Select Apply to save the schedule and scan type. 4. Select Create New under Asset Definitions to select the devices on the network to scan. An asset can be a single server or workstation computer on your network or a range of addresses on your network. You must add assets to the vulnerability scan before you can run a scan. To scan an entire network or part of a network you can just add the appropriate IP address range to the asset configuration. You can also add the IP addresses of Windows and Linux computers to include the user names and passwords for these machines. The vulnerability scanner will use these credentials to log into the computers and do more detailed vulnerability scanning. Page 20 Even if the asset is an address range you can add Windows and Linux credentials. The vulnerability scanner will attempt to log into all network device it finds using these credentials. 5. Enter the following information and select OK: Name Enter a name for this asset. Type Select IP Address to add a single IP address. Select Range to add a range of IP addresses to scan. IP Address Enter the IP address of the asset. (Type is IP Address.) Range Enter the start and end of the IP address range. (Type is Range.) Enable Scheduled Select to allow this asset to be scanned according to the schedule. Vulnerability Scanning Otherwise the asset is not scanned during a scheduled vulnerability scan. Windows Authentication Select to use authentication on a Windows operating system. Enter the username and password in the fields provided. For more information, see “Requirements for authenticated scanning and ports scanned” on page 22. Unix Authentication Select to use authentication on a Unix operating system. Enter the username and password in the fields provided. For more information, see “Requirements for authenticated scanning and ports scanned” on page 22. 6. Select Apply to save the configuration. To configure scanning - CLI To configure, for example, a standard scan to be performed every Sunday at 2:00am, you would enter: config netscan settings set scan-mode standard set schedule enable set time 02:00 set recurrence weekly set day-of-week sunday end To add an asset - CLI This example adds a single computer to the Asset list: config netscan assets edit 0 set name "server1" set addr-type ip set start-ip 10.11.101.20 set auth-windows enable set win-username admin set win-password zxcvbnm Fortinet Technologies Inc.

To view vulnerability scan results go to User & Device > Vulnerability Scan > Vulnerability Result. 2. Select any log entry to view log details. Requirements for authenticated scanning and ports scanned The effectiveness of an authenticated scan is determined by the level of access the FortiGate unit obtains to the host operating system. Rather than use the system administrator’s account, it might be more convenient to set up a separate account for the exclusive use of the vulnerability scanner with a password that does not change. The following sections detail the account requirements for various operating systems. Fortinet Technologies Inc.
