4 Rules and rule sets Rule configuration Create a sample rule This section explains in detail how to create a sample rule. Creating new rules is one of the activities you can complete to modify the implemented rule set system. Note: The rule already exists in one of the library rule sets, but under a slightly different name (Block if virus was found). Rule Name Block if virus was detected Criteria Action Antimalware.Infected equals true –> Block Procedure Complete the following procedure to create this rule: Note: Comments in italics explain what you are doing through the step or steps that follow. 1 Go to Policy | Rule Sets. Choosing a rule set for the rule 2 From the rule sets tree, select Gateway Antimalware as the rule set for the rule. The rule set and its current rules appear on the settings pane. Opening the Add Rule window 3 On the settings pane, click Add Rule. The Add Rule Window opens with the Name step selected. In the main window area, items appear for adding a name and other general settings. Adding general settings 4 Add the following general settings: a Name — Type Block if virus was detected. b Enable rule — Deselect this checkbox, so the sample rule gets not enabled. c Comment — Skip this optional substep. Adding the criteria 5 Select Rule Criteria. Items for adding the criteria appear. 6 Click Add. The Add Criteria window opens. 7 Add the criteria of the rule (Antimalware.Infected ... equals true): a From the Property list, select Antimalware.Infected. b In the Settings list, leave the default, which is Gateway Antimalware . The Anti-Malware module runs with these settings when it scans web objects, using virus signatures and proactive methods. c In the Operator list, leave equals, the default value. d In the Parameter area, select true from the Value list as operand (parameter) for the criteria. Note: (Boolean) is displayed in brackets next to Parameter. Antimalware.Infected is a property of the Boolean type. When it is selected, its parameter must have the same type. 8 Click OK. The Add Criteria window closes and the added criteria appears in the main window area. 104 McAfee Web Gateway 7.1.5 Product Guide
Adding the action 9 Select Action. Items for adding an action appear in the main window area. 10 Add an action with special settings (Block): a From the Action list, select Block. b From the Settings list, select Virus Found. Rules and rule sets Rule configuration 4 Under these settings, a block message is sent to the user who requested an object when the object is blocked. Reviewing the rule 11 Skip the Events step and select Summary to review what you have configured. Completing the sample configuration 12 Click Finish. The Add Rule window closes and the new rule appears in the Gateway Antimalware rule set. Note: The rule is grayed out because it is not enabled. 13 Click Save Changes. For more information, see About rule sets, Adding a rule, and Block if virus was found (Sample rule). Sample rules This section explains in detail three sample rules from the library rule sets of the appliance: • Do not filter URLs in Global Whitelist • Block URLs whose category is in Category BlockList • Block if virus was found Note: The Block if virus was found rule is also used in another section of this guide as an example for explaining step by step how a rule is created. For more information, see Create a sample rule. Do not filter URLs in Global Whitelist (Sample rule) This rule can be included in rule set for global whitelisting. Rule Name Do not filter URLs in Global Whitelist Criteria Action URL matches in list GlobalWhitelist –> Stop Cycle In plain text, the rule could be rendered as follows: If a URL is on a particular global whitelist, stop the current processing cycle. Purpose of the rule The rule is implemented to provide you with a means of ensuring that particular URLs can be accessed by the users of your network and are not blocked by any other rules. To achieve this, URLs are entered on a whitelist. If a whitelist URL is requested, the rule stops processing the request cycle. This means all following rules of this cycle, including those that might eventually block the URL, are not processed. When this rule and its rule set are implemented in a rule set system, it should obviously be placed at the beginning of the system to ensure there are no rule sets before it that block URLs. In this case, the whitelisting rule is truly global. It overrules all other measures that might be taken for URLs by the implemented rule set system. McAfee Web Gateway 7.1.5 Product Guide 105
