  Configure ImageMagick policies.

Domains include system, delegate, coder, filter, path, or resource.

Rights include none, read, write, and execute.  Use | to combine them,
  for example: "read | write" to permit read from, or write to, a path.

Use a glob expression as a pattern.

Suppose we do not want users to process MPEG video images:

Here we do not want users reading images from HTTP:

Lets prevent users from executing any image filters:

The /repository file system is restricted to read only.  We use a glob
  expression to match all paths that start with /repository:
  
    <policy domain="path" rights="read" pattern="/repository/*" />

Let's prevent possible exploits by removing the right to use indirect reads.
 
    <policy domain="path" rights="none" pattern="@*" />
 
  Any large image is cached to disk rather than memory:

Note, resource policies are maximums for each instance of ImageMagick (e.g.
  policy memory limit 1GB, -limit 2GB exceeds policy maximum so memory limit
  is 1GB).
