Comparing Two File Policies
License: 
Protection
To review policy changes for compliance with your organization’s standards or to optimize system 
performance, you can examine the differences between any two file policies, or two revisions of the same 
policy. 
The file policy comparison view displays two file policies or revisions in a side-by-side format, with the 
time of last modification and the last user to modify displayed next to each policy name. Differences 
between the two policies are highlighted:
  •
Blue indicates that the highlighted setting is different in the two policies, and the difference is noted 
in red text. 
  •
Green indicates that the highlighted setting appears in one policy but not the other.
You can navigate through the differences by clicking 
Previous
 and 
Next
. The double-arrow icon (
centered between the left and right sides moves, and the 
Difference 
number adjusts to identify which 
difference you are viewing. Optionally, you can generate a file policy comparison report, which is a PDF 
version of the comparison view.
To compare two file policies:
Access: 
Admin/Access Admin
Step 1
Select 
Policies > Files.
The File Policies page appears.
Step 2
Click 
Compare Policies
.
The Select Comparison dialog box appears.
Step 3
From the 
Compare Against
 drop-down list, select the type of comparison you want to make:
  •
To compare two different policies, select either 
Running Configuration
 or 
Other Policy
. The practical 
difference between the two options is that if you select 
Running Configuration
, the system limits one 
of your comparison choices to the set of currently applied file policies.
  •
To compare revisions of the same policy, select 
Other Revision
.
The dialog box refreshes, displaying your comparison options.
Step 4
Depending on the comparison type you selected, you have the following choices:
  •
If you are comparing two different policies, select the policies you want to compare: 
Policy A
 or 
Target/Running Configuration A
, and 
Policy B
.
  •
If you are comparing revisions of the same policy, select the 
Policy
 you want to use, then select the 
two revisions: 
Revision A
 and 
Revision B
. Revisions are listed by date and user name.
Step 5
Click
 OK
.
The comparison view appears.
Step 6
Optionally, click 
Comparison Report 
to generate the access control policy comparison report.
