In This Section: |
The Protection browser shows the Threat Prevention Software Blades protection types and a summary of important information and usage indicators.
These are some of the default columns in the IPS protections summary table.
Column |
Description |
---|---|
Protection |
Name of the protection. A description of the protection type is shown in the bottom section of the pane. |
Industry Reference |
International CVE or CVE candidate name for attack. |
Performance Impact |
How this protection affects the performance of a Security Gateway. If possible, shows an exact figure. |
Severity |
Probable severity of a successful attack on your environment. |
Confidence Level |
How confident IPS is in recognizing the attack. |
profile_name |
The Activation setting for the protection for each IPS profile. |
You should activate protections of Critical and High Severity, unless you are sure that you do not want the specified protection activated.
For example, if a protection has a rating of Severity: High, and Performance Impact: Critical, make sure that the protection is necessary for your environment before you activate the protection.
Some attack types are less severe than others, and legitimate traffic may sometimes be mistakenly recognized as a threat. The confidence level value shows how well the specified protection can correctly recognize the specified attack.
The Confidence parameter can help you troubleshoot connectivity issues with the firewall. If legitimate traffic is blocked by a protection, and the protection has a Confidence level of Low, you have a good indication that more granular configurations might be required on this protection.
Some protections require the use of more resources or apply to common types of traffic, which adversely affects the performance of the gateways on which they are activated.
Note - The Performance Impact of protections is rated based on how they affect gateways of the R80.10 version. The Performance Impact on other gateways may be different than the rating listed on the protection.
For example, you might want to make sure that protections that have a Critical or High Performance Impact are not activated unless they have a Critical or High Severity, or you know the protection is necessary.
If your gateways experience heavy traffic load, be careful about activating High/Critical Performance Impact protections on profiles that affect a large number of mixed (client and server) computers.
Use the value of this parameter to set an optimal protection profile, in order to prevent overload on the gateway resources.
The IPS protections are divided into two main types:
The IPS Protections summary lets you quickly browse all IPS protections and their settings.
To show IPS protections:
You can search the Protections page by protection name, engine, or by any information type that is shown in the columns.
To filter the protections:
The Filters pane opens and shows IPS protections categories.
A window opens and shows the IPS protections categories.
The category is added to the Filters pane.
To sort the protections list by information:
Click the column header of the information you want.
Each profile is a set of activated protections and instructions for what IPS does if traffic inspection matches an activated protection. The procedures in this section explain how to change the action for a specified protection.
To manually activate a protection in all profiles:
The IPS Protections page opens.
Make sure that the action is on all profiles.
To manually activate a protection for a specific profile:
You can activate the protection for one profile and deactivate it for another profile. It will be active for some gateways and inactive for others.
If the protection is inactive according to the policy, you can override the policy preference or change the policy criteria.
To override the settings for this one protection, continue with this procedure.
You can remove the manually activated IPS protections and restore them to the profile settings. You can remove overrides on one protection, on selected protections or on all protections at the same time.
To remove IPS protection overrides on selected protections:
The IPS Protections page opens.
Note - Press CTRL to select more than one protection.
A warning message opens.
To remove IPS protection overrides from all protections:
The Profile Cleanup window opens.
To edit core protections:
Note - to filter for core protections, select Type Core in the Filters pane.
Check Point constantly develops and improves its protections against the latest threats. You can immediately update IPS with real-time information on attacks and all the latest protections. You can manually update the IPS protections and also set a schedule when updates are automatically downloaded and installed. IPS protections include many protections that can help manage the threats against your network. Make sure that you understand the complexity of the IPS protections before you manually modify the settings.
Note - To enforce the IPS updates, you must install policy.
To update IPS Protections:
To manually update IPS Protections:
The file directory opens.
For troubleshooting or for performance tuning, you can revert to an earlier IPS protection package.
To revert to an earlier protection package:
You can configure a schedule for downloading the latest IPS protections and protection descriptions.
