The regular expression used in the Passwords policy template results in detection failures on endpoints due to limitations of the Lookahead and Lookbehind assertions. The Passwords policy template was introduced in Symantec Data Loss Prevention 16.0 MP1.

Resolve this issue by modifying the regular expression to remove the second, third, and fourth characters. You can copy the updated regular expression shown below.
