What Are Policy Rules?
...
A policy rule is a statement that gives you options to allow, deny, apply an encryption key, and audit access attempts on a GuardPoint based on a combination of 6 criteria. The policy rules are analyzed in descending order, similar to firewall rules, which means the order of these rules is important.
Create a Policy with Security Rules
...
Log into your DSM as the Security Administrator.
In the menu bar, click Policies.

Click Add Online Policy.
In Name, enter a descriptive name.
In Description, enter a short description to help identify the purpose of this policy, such as Database_Policy.
(Optional) Select Learn Mode.
Armor recommends that you select Learn Mode when you create and apply a new policy.
The cloning feature allows you to create an identical policy for future GuardPoints that require the same access rules.
To learn more about Learn Mode, see Create a Starter Policy with Learn Mode.
Under Security Rules, click Add.

Resource - Specifies which folders or files in a GuardPoint can be accessed.
User - Specifies the users or user groups that can access the GuardPoint.
Process - Specifies the executables that can access the GuardPoint, such as usr/lib/exec/mysql.exe.
When - Specifies the date and time range when files can be accessed.
Action - Specifies the allowed file action, such as read, write, remove, rename, make directory, etc.
Effect - The following options correspond to Effect:
Permit - Permits access to the data.
Apply Key - Enables users and processes the ability to encrypt and decrypt data inside of the GuardPoint.
Audit - Creates an entry in the DSM message logs that describes what data is being accessed, when the attempt was made, and the security rule being applied.
Deny - Denies access to the data. You can also deny users or processes by simply leaving them out of the policy rules.
