Prevent Data Leaks with M+Guardian
Hi everyone!
Did you know that with M+Guardian, it’s super easy to create a policy to protect against data leaks?
For instance, if you’re an organization that collects people’s Social Security numbers, you can make sure that email messages being sent from your organization do not contain any Social Security numbers. Leaking a Social Security number would be a HUGE data breach!
Here’s how to configure M+Guardian to stop it from happening:
1. Choose Policies > Content Filter > Create Content Filter Policy.
2. Under Create a Policy, enter a name for your policy, and then click Save Changes.
3. Select your new policy.
4. Under Filter Type, choose Regular Expressions.
5. In the Filter Value dialog box, enter the following number sequence: [0-9][0-9][0-9].[0-9][0-9][0-9].[0-9][0-9][0-9][0-9].
6. Under Action, select which message action you wish to take on a message which meets this criteria. Depending on your corporate epolicy, you may wish to select from the following options:
• Delete the Message: This option deletes the message containing the SSN. Use this option alone or use this option in conjunction with the BCC to or the Send Notification option.
• BCC to: This option allows you to specify where a blind carbon copy of the message should be sent. Use this option notify a designated individual about a violation in corporate epolicy without notifying the sender of the message.
• Send Notification: This option allows you to choose a Notification policy. Notification policies can be configured to automatically send email notifications to the sender and/or administrators when a message containing an SSN is detected in the system. Notification Policies are created by choosing Policies > Notifications. For more information, see "Notifications".
7. Click Save Changes to save your policy.
8. Choose Domains & Users. Highlight the name of your domain and click the Sender Policies tab.
9. Under Content Filtering Policy, click Add New to view a list of available policies and then highlight your previously-created policy.
10. To apply the policy to all users in the organization, do not select
Allow this policy to be overridden.
11. Click Save Changes to save your changes.
That’s it! Your organization is now protected from a Social Security number data breach. A similar procedure can be followed to protect against other types of sensitive data being leaked from the email system.
