How to configure Symfony’s Security Access Control in Laravel 4



Symfonic 4 Security Access control allows developers to specify access types to applications and services, allowing them to restrict access to specific kinds of content and user data.

Laravel 5 allows developers the option to specify these access types on a per-service basis.

Symfony Security Access controls can be configured to prevent the following:Application data from being shared with third parties.

Application code from being executed by third parties or by Symfonies own code.

Database connections to the database being made from the application or service to third parties, or to the server of a third party.

Security access can be limited by the app’s developer’s policies, and can be controlled with the app settings page.

Laravel Security Access Controls can be used to restrict the scope of security exceptions and exceptions that the app can receive, as well as to provide a default access control policy.

This article describes the default access controls that Symfonia 4 provides.

Symfonics default policy can be overridden by a developer.

The following table lists the default policies and exceptions Symfonys default policy provides.

Policy Default exceptions Symphony SecurityAccess controlsSymfonic SecurityAccess control:Allow the following access types:Access type Description NoAllowDatabaseConnection NoAllowApplicationConnection NoDenyDatabaseConnectionNoDenyApplicationConnectionAllow the application to be used as a connection to the web server NoDenialApplicationConnection Allow the application access to the application database.

SecurityAccesses allow applications to restrict application access.

In order to use these policies, the application must have a Symfones default policy.

To use a Symphonic Security Access Policy, first create a Symfson configuration file in the app/config/SecurityAccessPolicy.php file.

Then, create an access policy file in app/controllers/SecurityPolicy.xml file in your project’s root directory.

Add the following code to the top of the file: <exceptions action="RestrictionException" type="" excluded="net-conn.exception" exclusion-rule="" exclude-rule="*-exclude-rule" excluded-rule-string="" excluded-excluded-reason="" excluded_excluded_exclusion="" excluded "net-connection" exclusion_action="" excluded="" excluded2="netconn.

ExcessConnection” exclude=”” excluded3_string=”” exclude3_reason=”” exclude2=”” excluded1=”” excluded0=”” excluded4=”” excluded” excluded0_string” exclude0_reason2=”” exclude0=”” exclude1=”” exclude4_string=”netConnections.

ExcludedConnection” exclusion=”true”/> SecurityAccess Policy settings can be changed by setting an access_type policy to a value.

For example, you can add a security policy that only allow the following exception types:AllowDatabaseException,AllowApplicationException,DenyUserConnection,DenyingDatabaseConnection,RestrictException,RestrictedUserConnectionAllow this exception to be excluded from all access to a particular app, server, or service, or from the app or service that is connected to a database.

The following example uses the AllowDatabaseException exception, and sets a security_access_policy to deny the app access to that app.

SecurityPolicy settings can also be changed using the Allow exception access type policy, which is a value that specifies the exception type that should be allowed for that application, server or service.

The example below allows the application’s permission to access
