For Web applications, the recommended services are the Web browsing services. If the match settings of the application are configured to Customize , the blocked application is matched on the customized services.
It is not matched on all ports. Note - This setting applies to all applications, not only to Web applications. Checkbox: Match web application on 'Any' port when used in 'Block' rule. You can create custom applications, categories or groups, that are not included in the Check Point Application Database.
Note - If the application or site URL is defined as a regular expression you must use the correct syntax. These are the Action options:. Optionally, shows a UserCheck Block message. Limits the bandwidth that is permitted for a rule. Add a Limit object to configure a maximum throughput for uploads and downloads. Enable Identity Captive Portal.
Redirects HTTP traffic to an authentication captive portal. After the user is authenticated, new connections from this source are inspected without requiring authentication.
These are the Action options that work with UserCheck:. Shows a UserCheck Ask message. The message asks users to confirm that it is necessary that they go to the application or site.
Confirm UserCheck. This shows some examples of URL Filtering and Application Control rules for a typical policy that monitors and controls Internet browsing. The Hits and Install On columns are not shown. Note - The Remote Administration category blocks traffic that uses the Radmin application. If this rule is placed before rule 3, then this rule can also block Radmin for the IT department.
Use the Hit Count feature to track the number of connections that each rule matches. You can show Hit Count for the rules in these options:. Hit Count works independently from logging and tracks the hits even if the Track option is None.
Note - If you see a rule with a zero hit count it only means that in the Security Gateways enabled with Hit Count there were no matching connections. There can be matching connections on other Security Gateways. The timeframe setting that defines the data collection time range is configured globally.
If necessary, you can disable Hit Count for one or more Security Gateways. After you enable or disable Hit Count you must install the Policy for the Security Gateway to start or stop collecting data.
These are the options you can configure for how matched connection data is shown in the Hits column:. For example, K represents thousand connections and 2M represents 2 million connections.
Right-click the heading row of the Rule Base and select Hits. The Security Management Server comes with two preconfigured inspection profiles for the Firewall:. When you configure a Security Gateway, the Default Inspection profile is enabled for it. You can also assign the Recommended Inspection profile to the Security Gateway, or to create a custom profile and assign it to the Security Gateway.
The Inspection Settings window opens. Select Capture Packets , if you want to be able to examine packets that were blocked in Drop rules. To assign an Inspection Settings profile to a Security Gateway:. The Exception Rule window opens. Field Description No.
Rule number in the Rule Base Layer. Hits Number of connections that match this rule. Name Name that the system administrator gives this rule. Source Network object that defines where the traffic starts. Destination Network object that defines the destination of the traffic. Action Action that is done when traffic matches the rule. Track Tracking and logging action that is done when traffic matches the rule.
Install On Network objects that will get the rule s of the policy. Time Time period that this rule is enforced. Comment An optional field that lets you summarize the rule. Explicit rules The rules that the administrator configures explicitly, to allow or to block traffic based on specified criteria.
Implied rules The default rules that are available as part of the Global properties configuration and cannot be edited. You can only select the implied rules and configure their position in the Rule Base: First - Applied first, before all other rules in the Rule Base - explicit or implied Last - Applied last, after all other rules in the Rule Base - explicit or implied, but before the Implicit Cleanup Rule Before Last - Applied before the last explicit rule in the Rule Base Implied rules are configured to allow connections for different services that the Security Gateway uses.
The implicit rules do not show in the Rule Base. Configuring the Implied Rules Some of the implied rules are enabled by default. Select a rule to enable it, or clear a rule to disable it. For the enabled rules, select the position of the rules in the Rule Base : First - The rule is applied before any other rule in the Rule Base Last - The rule is applied if all other rules in the Rule Base were applied and none of them matched Before Last - The rule is applied before the last explicit rule, if none of the other rules in the Rule Base matched Click OK and install the policy.
Visual Division of the Rule Base with Sections To better manage a policy with a large number of rules, you can use Sections to divide the Rule Base into smaller, logical components.
The implicit cleanup rule for it is set to Drop all traffic that is not matched by any rule in this Layer. The implicit cleanup rule for it is set to Accept all traffic that is not matched by any rule in this Layer. There are no other Policy Layers. Order of Rule Enforcement When a packet arrives at the gateway, the gateway checks it against the rules in the top Policy Layer, sequentially from top to bottom, and enforces the first rule that matches a packet.
Explicit Rules - These are the rules that you create. Before Last Implied Rules - Applied before the last explicit rule. Last Explicit Rule - We recommend that you use a Cleanup rule as the last explicit rule. Last Implied Rule - Remember that although this rule is applied after all other explicit and implied rules, the Implicit Cleanup Rule is still applied last. Implicit Cleanup Rule - The default rule that is applied if none of the rules in the Policy Layer match.
For more, see: sk Managing Network Access Control A firewall controls access to computers, clients, servers, and applications through a set of rules that comprise an Access Control Rule Base.
A strong Access Control Rule Base: Only allows authorized connections and prevents vulnerabilities in a network Gives authorized users access to the correct internal resources Efficiently inspects connections and uses network resources efficiently Ensuring a Secure Network Access A robust security policy must have some basic rules in its Rule Base. Basic Rules These are basic Access Control rules we recommend for all Rule Bases: Stealth rule that prevents direct access to the Security Gateway Cleanup rule that drops all traffic that is not allowed by the earlier rules in the policy Note - There is also the implicit drop rule that drops all traffic that did not match all other rules.
When a connection matches the Stealth rule, an alert window opens in SmartView Monitor. Critical subnet - Traffic from the internal network to the specified resources is logged. Only HTTP traffic is allowed.
When a packet matches the Tech support rule, the Alert action is done. This traffic is not logged. Mail and Web servers - Allows incoming traffic to the mail and web servers that are located in the DMZ. Does not allow SMTP connections to the internal network, to protect against a compromised mail server.
Clean up rule - Drops all traffic. All traffic that is allowed matched one of the earlier rules. Preventing IP Spoofing IP spoofing replaces the untrusted source IP address with a fake, trusted one, to hijack connections to your network.
Example: The diagram shows a Gateway with interfaces A and B, and C, and some example networks behind the interfaces. For the Gateway, anti-spoofing makes sure that All incoming packets to A come from Configuring Anti-Spoofing Make sure to configure Anti-Spoofing protection on all the interfaces of the Security Gateway, including internal interfaces.
From the navigation tree, select Network Management. Click Get Interfaces. Click Accept. Select an interface and click Edit. From the navigation tree, select General. In the Topology section of the page, click Modify. To monitor traffic and to learn about the network topology without dropping packets, select this option together with the Spoof Tracking Log option.
Configure Anti-Spoofing exceptions optional - addresses, from which packets are not inspected by Anti-Spoofing : Select Don't check packets from. Select an object from the drop-down list, or click New to create a new object. Configure Spoof Tracking - select the tracking action that is done when spoofed packets are detected: Log - Create a log entry default Alert - Show an alert None - Do not log or alert Click OK twice to save Anti-Spoofing settings for the interface.
Excluding Specific Internal Addresses In some configurations, the Firewall must allow connections with an internal IP address from an external source. Managing URL Filtering and Application Control Today there are many challenges for businesses to keep up with security requirements of social media and Web 2. For example: Malware threats - Popular applications like Twitter, Facebook, and YouTube can cause users to download viruses unintentionally. When users download files and use torrents, they can also let malware into your network.
Bandwidth hogging - Applications that use a lot of bandwidth can reduce the performance for important business applications. Loss of productivity - Employees can spend time on social networking and other applications that can decrease business productivity. Content control - Prevent Internet access to websites with inappropriate content, such as sex and violence. Manage Bandwidth Consumption - Configure rules to limit the available network bandwidth for specified users or groups.
You can define separate limits for uploading and downloading. Keep Your Policies Updated - The Application Database is updated regularly, which helps you makes sure that your Internet security policy has the newest applications and website categories. Security Gateways connect to the Check Point Online Web Service to identify new social networking widgets and website categories.
UserCheck helps users understand that certain websites are against the company's security policy. It also tells users about the changes in Internet policy related to websites and applications. Create Custom Objects - In addition to the hundreds of default objects, you can create custom objects, to better manage the use of Internet by your users.
Create objects for applications, websites, categories and groups, and use them in your security policy rules. UserCheck on a computer The UserCheck client is installed on endpoint computers. This client: Sends messages for applications that are not based on Internet browsers, such as Skype and iTunes, and Internet browser add-ons and plug-ins.
Shows a message on the computer when it cannot be shown in the Internet browser. From the navigation tree, click General Properties. Click OK. In the Access Control section, click the plus sign. Click New Layer. In the Blades section, enter a name for the Layer. Click OK and the Layer Editor window closes. Click OK and the Policy window closes. Install the policy. A rule can contain one or more: Applications Web sites Services Default categories of Internet traffic Custom categories or groups that you create, that are not included in the Check Point Application Database.
Application Matching If an application is allowed in the policy, the rule is matched only on the recommended services of the application. You can change the default match settings for applications. Configuring Matching for an Allowed Application You can configure how a rule matches an application or category that is allowed in the policy.
You can configure the rule to match the application: On any service, or On a specified service. Select Match Settings. Select an option: To match the application with all services, select Any.
To match the application on specified services: Select Customize. Add or remove services. To match the application with all services and exclude specified services: Select Customize. Add the services to exclude. Select Negate. Configuring Matching for Blocked Applications By default, if an application is blocked in the policy, it is blocked on all services.
Selected - This is the default. If an application is blocked in the Rule Base, the application is matched to Any port. Not selected - If an application is blocked in the Rule Base, the application is matched to the services that are configured in the application object of the application. However, some applications are still matched on Any. These are applications Skype, for example that do not limit themselves to a standard set of services.
To add applications to a rule, select the Application Control Layer. Search for the services, sites, applications, or categories. Creating Custom Applications, Categories, and Groups You can create custom applications, categories or groups, that are not included in the Check Point Application Database.
Select the Application Control Layer. The Application viewer window opens. Enter a name for the object. Enter one or more URLs. Enter a description for the object. Drop Blocks the traffic. Limit Limits the bandwidth that is permitted for a rule. Ask Shows a UserCheck Ask message.
