regex to filter weak passwords

[robcivitello]

Hello, we have a need to respond to a password deficiency audit finding, because we do not currently have filters in place in Saviynt to block the following scenarios.  Is this something that can be achieved with regex?  If so, what would that look like?

- Keyboard sequence with more than 3 characters, such as “qwerty”

 - Repeating patterns with 3 or more instances, such as “BuyBuyBuy”

- Sequences of more than 3 consecutive characters, such as “wxyz” or "1234"

To achieve this, you can use blacklisted words and blacklisted attribute feature under password policy. 

to enable, select YES from the password policy and add the blacklist words under blacklist.txt in filedirectory.
