Protected rule resource matching rule expressions

Protected Policy rules require a resource matching rule to determine if an end user matches a rule. Resource matching rules are based on regular expression which can be very complex.

Access Gateway provides a set of menu items with common baseline expressions, which can be selected and then modified to meet a specific need.

Modifying a protected rule based on a provided expression

To modify a protected rule:

1. Navigate to the Access Gateway Admin UI console.

2. Select the Applications tab.

3. Select an application that contains an existing or needs a new protected rule and click Edit.

4. Select the Policies sub-tab.
5. Select an existing protected rule and click Edit. Alternatively, create a new protected rule. For details of adding a new protected rule, see Manage application policy.
6. Click the policy menu and select one of the Predefined policies, then click Use this.
   
   
7. Modify the policy as required.

Predefined policies

The following predefined policies are provided:

Policy	Description
Allow Group	Allows access to the given resource if the end user is a member of the single specified group. Example: Groups=((?=(|.:)Everyone(R|:.*)))
Deny Group	Denies access to the given resource if the end user is a member of the single specified group. Example: Groups=((?!(|.*:)Everyone(\R|:.*)))
Allow RemoteIP	Allows access to the given resource if the end users IP matches the provided regular expression. Example: RemoteIP=(?=192\..*)
Deny RemoteIP	Denies access to the given resource if the end users IP matches the provided regular expression. Example: RemoteIP=(?!192\..*)
Allow OR Groups	Allow access to resource if user has group membership to one OR another group. Example: Groups=((?=(|.*:)Everyone(\R|:.*)))|((?=(|.*:)Group2(\R|:.*)))
Allow AND Groups	Allow access to resource if user has group membership to one AND another group. Example: Groups=((?=(|.*:)Everyone(\R|:.*)))((?=(|.*:)Group2(\R|:.*)))
Allow User	Allow access to resource if UserName matches. Example: UserName=user@example.com
Deny User	Deny access to resource if UserName matches. Example: UserName=(?!test@example.com)
Allow Group AND User	Allow access to resource if user has group membership AND UserName matches. Example: (?=.*Groups=(?=(|.:)Everyone(R|:.*)))(?=.*UserName=user1@domain.tld)
Allow Group AND Deny User	Allow access to resource if user has group membership AND UserName is not matches. Example: (?=.*Groups=(?=(|.:)Everyone(R|:.*)))(?=.*UserName=(?!user3@domain.tld))

Once selected the expression can be modified to meet a specific need.

Resource Matching Rule fields

Resource matching rules are regular expressions based on application attributes. Predefined polices use attributes such as Groups, UserName and RemoteIP. Any application attribute can be used in a resource matching rule. Common attribute mappings include:

Data Source	Field	Name
IDP	Groups	Groups
IDP	email	UserName
IDP	login	login
Provided and not required to be defined as attributes.		RemoteIP USER_AGENT
