FortiOS 6.2 Best Practices

General considerations

  1. For security purposes, NAT mode is preferred because all of the internal or DMZ networks can have secure private addresses. NAT mode policies use network address translation to hide the addresses in a more secure zone from users in a less secure zone.
  2. Use virtual domains (VDOMs) to group related interfaces or VLAN subinterfaces. Using VDOMs will partition networks and create added security by limiting the scope of threats.
  3. Use transparent mode when a network is complex and does not allow for changes in the IP addressing scheme.

System and performance

By implementing the following best practices for system and performance, you will ensure maximum efficiency of your FortiGate device. Be sure to read everything carefully, particularly the section that concerns shutting down the FortiGate system, in order to avoid potential hardware issues.

Performance

  • Disable any management features you do not need. If you don’t need SSH or SNMP, disable them. SSH also provides another possibility for would-be hackers to infiltrate your FortiGate unit.
  • Put the most used firewall rules to the top of the interface list. l Log only necessary traffic. The writing of logs, especially if to an internal hard disk, slows down performance. l Enable only the required application inspections.
  • Keep alert systems to a minimum. If you send logs to a syslog server, you may not need SNMP or email alerts, making for redundant processing.
  • Establish scheduled FortiGuard updates at a reasonable rate. Daily updates occurring every 4-5 hours are sufficient for most situations. In more heavy-traffic situations, schedule updates for the evening when more bandwidth can be available.
  • Keep security profiles to a minimum. If you do not need a profile on a firewall rule, do not include it. l Keep VDOMs to a minimum. On low-end FortiGate units, avoid using them if possible. l Avoid traffic shaping if you need maximum performance. Traffic shaping, by definition, slows down traffic.

Shutting down

Always shut down the FortiGate operating system properly before turning off the power switch to avoid potentially catastrophic hardware problems.

To power off the FortiGate unit – GUI:

  1. Go to Dashboard.
  2. In the System Resources widget, select Shutdown.

To power off the FortiGate unit – CLI:

execute shutdown

Once this has been done, you can safely turn off the power switch or disconnect the power cables from the power supply.

Migration

Network administrators are often reluctant to change firewall vendors due to the perception that the migration process is difficult. Indeed, there is no point hiding the fact that moving to a new vendor requires careful consideration. But concern over the potential pain of migration should not stand in the way of adopting new security technologies. The purpose of this chapter is to describe the best practices for performing such migrations and ultimately to ease the migration process itself.

Information gathering

It is always best practice to perform a full network audit prior to any migration. This should include:

  • Full back up of all security systems (including switches, routers) in case a back-out needs to be performed. l Physical and logical network diagram with visual audit

Understanding exactly where cables run in the network and verifying they are all correctly labeled is essential to avoid mistakes and unnecessary downtime during the upgrade. Don’t overlook simple things such as:

  • Do I have enough spare interfaces on my switches? l Do I have the right fiber (single/multi mode) and right connectors (LC, FC, MTRJ, SC, ST)?
  • Do I have spare cables? (in the heat of the moment, it is a simple mistake to break an RJ-45 connector or damage a fiber) l Do I have space in the rack for the new equipment? l Do I have enough power sockets?

No matter how securely a FortiGate is configured in the network, it cannot help if it has been bypassed; visually checking where the device sits in the network in relation to other devices will ensure you are maintaining security and verify the network diagram is ‘as built’. Details of all networks including subnet masks should be documented at this point to ensure that the replacement device is configured with the correct information.

Object and policy migration

Whilst we have suggested some level of manual review is included in the policy migration, it can be useful to be able to automatically migrate simply between another vendor’s format and the FortiGate format. The FortiGate policy format is text based and can easily be cut and pasted into from other vendor formats however, responding to the high customer demand to migrate away from other vendors, Fortinet have released an automatic configuration migration tool at http://convert.fortinet.com to simplify this process. Supporting Cisco ACLs, PIX, ASA, Check Point, and Juniper, the Converter can securely upload and convert the policy into the Fortinet format.

Testing and validation

This is an important process and should be tested offline first wherever possible i.e. configure the policy in the lab or on a test network and verify that the required access permissions are being implemented. To really test the solution out, the FortiGate can be implemented on the live network with a different gateway IP and the selected user pointed to the new gateway. This allows a staged approach to migrating the new platform into the network ensuring that the process does not interrupt day to day operations.

Going live and obtaining feedback

If testing and validation is successful at this point, you can migrate to the new firewall either by switching IP’s and removing the old devices or by changing the default gateway in DHCP. Once the firewall is in place, acceptance testing will of course need to be carried out and an iterative process of tuning undertaken to finalize the configuration.

Adding new services

The Fortinet solution will have a plethora of additional features compared to your previous vendor and it is very tempting to start switching them on but it is a good idea to wait and validate the new firewall as was previously configured before adding new functions as this simplifies testing and problem diagnosis. Finally complete the migration (don’t forget about the Plan Do Check Act Cycle) by adding any new services that were requested and learn about the multiple features you have available with the FortiGate appliance.

  • FortiClient (Mac OS X) SSL VPN requirements l Use of dedicated management interfaces (mgmt1 and mgmt2) l Using FortiAnalyzer units running older versions on page 8

FortiGuard Security Rating Service

Not all FortiGate models can support running the FortiGuard Security Rating Service as a Fabric “root” device. The following FortiGate platforms can run the FortiGuard Security Rating Service when added to an existing Fortinet Security Fabric managed by a supported FortiGate model: l FGR-30D l FGR-35D l FGT-30E l FGT-30E-MI l FGT-30E-MN l FGT-50E l FGT-51E l FGT-52E l FWF-30E l FWF-30E-MI l FWF-30E-MN l FWF-50E-2R l FWF-50E l FWF-51E

FortiGate hardware limitation

FortiOS 5.4.0 reported an issue with the FG-92D model in the Special Notices > FG-92D High Availability in Interface Mode section of the release notes. Those issues, which were related to the use of port 1 through 14, include:

  • PPPoE failing, HA failing to form. l IPv6 packets being dropped. l FortiSwitch devices failing to be discovered. l Spanning tree loops may result depending on the network topology.

Special Notices                                                                                                                                                          7

FG-92D does not support STP. These issues have been improved in FortiOS 5.4.1, but with some side effects with the introduction of a new command, which is enabled by default:

config global set hw-switch-ether-filter <enable | disable>

When the command is enabled:

  • ARP (0x0806), IPv4 (0x0800), and VLAN (0x8100) packets are allowed. l BPDUs are dropped and therefore no STP loop results. l PPPoE packets are dropped. l IPv6 packets are dropped. l FortiSwitch devices are not discovered. l HA may fail to form depending the network topology.

When the command is disabled:

  • All packet types are allowed, but depending on the network topology, an STP loop may result.

CAPWAP traffic offloading

CAPWAP traffic will not offload if the ingress and egress traffic ports are on different NP6 chips. It will only offload if both ingress and egress ports belong to the same NP6 chip. The following models are affected: l FG-900D l FG-1000D l FG-2000E l FG-2500E

FortiClient (Mac OS X) SSL VPN requirements

When using SSL VPN on Mac OS X 10.8, you must enable SSLv3 in FortiOS.

Use of dedicated management interfaces (mgmt1 and mgmt2)

For optimum stability, use management ports (mgmt1 and mgmt2) for management traffic only. Do not use management ports for general user traffic.

 

Special Notices

Using FortiAnalyzer units running older versions

When using FortiOS 6.2.0 with FortiAnalyzer units running 5.6.5 or lower, or 6.0.0-6.0.2, FortiAnalyzer might report increased bandwidth and session counts if there are sessions that last longer than two minutes.

For accurate bandwidth and session counts, upgrade the FortiAnalyzer unit to 5.6.6 or higher, or 6.0.2 or higher.

Changes in default behavior

Upgrade Information

Supported upgrade path information is available on the Fortinet Customer Service & Support site.

To view supported upgrade path information:

  1. Go to https://support.fortinet.com.
  2. From the Download menu, select Firmware Images.
  3. Check that Select Product is FortiGate.
  4. Click the Upgrade Path tab and select the following:

l Current Product l Current FortiOS Version l Upgrade To FortiOS Version

  1. Click Go.

FortiClient Endpoint Telemetry license

Starting with FortiOS 6.2.0, the FortiClient Endpoint Telemetry license is deprecated and as a result there are two upgrade scenarios:

  • Customers using only a FortiGate device in FortiOS 6.0 to enforce compliance must install FortiClient EMS 6.2.0 and purchase a FortiClient Security Fabric Agent License.
  • Customers using both a FortiGate device in FortiOS 6.0 and FortiClient EMS running 6.0 for compliance enforcement, must upgrade both the FortiGate device to FortiOS 6.2.0, FortiClient to 6.2.0, and FortiClient EMS to 6.2.0.

Fortinet Security Fabric upgrade

FortiOS 6.2.0 greatly increases the interoperability between other Fortinet products. This includes:

l FortiAnalyzer 6.2.0 l FortiClient EMS 6.2.0 l FortiClient 6.2.0 l FortiAP 5.4.4 and later l FortiSwitch 3.6.9 and later

Upgrade the firmware of each product in the correct order. This maintains network connectivity without the need to use manual steps.

If Security Fabric is enabled, then all FortiGate devices must be upgraded to 6.2.0. When Security Fabric is enabled in FortiOS 6.2.0, all FortiGate devices must be running FortiOS 6.2.0.

 

Minimum version of TLS services automatically changed

For improved security, FortiOS 6.2.0 uses the ssl-min-proto-version option (under config system global) to control the minimum SSL protocol version used in communication between FortiGate and third-party SSL and TLS services.

When you upgrade to FortiOS 6.2.0 and later, the default ssl-min-proto-version option is TLS v1.2. The following SSL and TLS services inherit global settings to use TLS v1.2 as the default. You can override these settings.

l Email server (config system email-server) l Certificate (config vpn certificate setting) l FortiSandbox (config system fortisandbox) l FortiGuard (config log fortiguard setting) l FortiAnalyzer (config log fortianalyzer setting) l LDAP server (config user ldap) l POP3 server (config user pop3)

Downgrading to previous firmware versions

Downgrading to previous firmware versions results in configuration loss on all models. Only the following settings are retained:

l operation mode l interface IP/management IP l static route table l DNS settings l admin user account l session helpers l system access profiles

Amazon AWS enhanced networking compatibility issue

With this enhancement, there is a compatibility issue with older AWS VM versions. After downgrading a 6.2.0 image to an older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

To configure local-access profile:

config switch-controller security-policy local-access edit [Policy Name] set mgmt-allowaccess https ping ssh set internal-allowaccess https ping ssh

next

end

To apply local-access profile to managed FortiSwitch:

config switch-controller managed-switch edit [FortiSwitch Serial Number] set switch-profile [Policy Name] set access-profile [Policy Name]

next

end
