To optimize Fortinet IPS performance, consider excluding trusted IPs from inspection to reduce load. This simple tweak can make a big difference in system efficiency.

You can also set the IPS profile to scan only Critical & High severity threats during high CPU load periods to prevent overwhelming the system. This helps maintain a balance between security and performance.

One more thing to keep in mind is the IPS buffer size. If your system frequently enters fail-open mode, you can try increasing the IPS socket buffer size to allow more data buffering. This reduces the chances of overloading the IPS engine.

Here are some key IPS performance tips to keep in mind:

Remember to take caution when modifying the default IPS buffer size, as setting it too large can cause the system to enter conserve mode more frequently.

To get the most out of your FortiGate's performance, you can start by excluding trusted IPs from inspection to reduce load. This simple tweak can make a big difference in your network's speed and efficiency.

One way to optimize performance is to set your profile to scan only Critical & High severity during high CPU load. This helps ensure that your network remains secure without sacrificing speed.

Hardware acceleration is a powerful tool that can offload certain tasks to specialized processors. If your FortiGate supports it, you can enable hardware acceleration (CP/NP) to boost performance.

You should also keep your IPS signatures up-to-date via FortiGuard to ensure you're protected against the latest threats. This is an essential step in maintaining a secure network.

Here are some key performance tips to keep in mind:

GUI Configuration is a crucial step in setting up your security system. To access the GUI Configuration, go to Security Profiles > Intrusion Prevention.

From there, you can use the default IPS profile or create a custom one. Selecting the right threat level is also important, such as choosing to trigger alerts for critical or high-level threats only.

To attach the profile to a Firewall Policy, simply select the policy from the list. This will ensure that your security settings are enforced across all your network traffic.

You can also configure the IPS signature rate count threshold from the GUI by going to Security Profiles > Intrusion Prevention. Create or edit an IPS sensor, and within the sensor, edit the IPS signatures and filters.

The workflow of FortiGate is quite fascinating, and understanding it is essential to optimizing its performance.

Traffic enters FortiGate, where it's then analyzed by the IPS engine.

The IPS engine workflow is a four-step process that begins with traffic entering FortiGate.

Here's a breakdown of the IPS engine workflow:

This process ensures that all incoming traffic is thoroughly inspected and processed according to the configured policy.

Increasing the IPS socket buffer size can help reduce the chances of overloading the IPS engine, especially if the system enters fail-open mode frequently.

This is because a larger buffer size allows more data to be buffered, giving the IPS engine more time to process packets. The default socket size and maximum configurable value varies by model.

You can set the size of the IPS buffer, but be cautious not to make it too large, as this can cause the system to enter conserve mode more frequently due to higher memory usage.

If the socket-size is set too low, the system may enter IPS fail-open mode too frequently. The IPS engine samples packets and passes the data to the kernel based on the socket-size.

Here's a brief summary of the trade-offs to consider when adjusting the IPS buffer size:

When choosing how to track session counts, you have two options: accurate or heuristic. The accurate count uses more resources than the less accurate heuristic count.

The default setting for session count tracking is heuristic, which is a more resource-friendly option. This setting is suitable for most situations.

If you need a precise count of open sessions, you may want to consider switching to the accurate count method.

In this lab, a virtual topology was created in the ATC to focus on validating the IPS capabilities of Fortinet FortiGate NGFW.

The rate count threshold is a crucial setting in IPS signature rate-based settings. It specifies a rate count threshold that must be met before the signature is triggered.

You can configure this setting from the GUI by going to Security Profiles > Intrusion Prevention. Create or edit an IPS sensor, and within the sensor, edit the IPS signatures and filters.

Only IPS signatures have the rate-based settings option, IPS filters do not. Some settings are only available in the CLI.

To set the rate count threshold, you'll need to specify the count of the rate, which can range from 0 to 65535, with a default value of 0. This must be configured before you can set the other rate settings.

The rate duration, in seconds, can also be set, ranging from 0 to 65535, with a default value of 60.

There are two rate modes: continuous and periodical. You'll need to choose how the count threshold is met.

You can also track one of the protocol fields within the packet, such as the source IP, destination IP, DHCP client MAC, or DNS domain.

Fail-open is a configuration option that determines what happens when the IPS raw socket buffer is full, leaving no space in memory to create more sessions. This can be a critical decision for network administrators.

The default setting is to drop sessions, which means traffic will be blocked when the system enters fail-open mode. This is a safety mechanism to prevent network congestion.

However, you can enable fail-open to allow traffic to continue flowing without IPS scanning. This will affect all protocols inspected by FortiOS IPS protocol decoders, including HTTP, HTTPS, FTP, and more.

Note that sessions offloaded to Nturbo do not support fail-open. When the Nturbo data path is overloaded, traffic will be dropped regardless of the fail-open setting.
