Validating strong passwords awk
Passwords are created either automatically (using randomizing equipment) or by a human; the latter case is more common.The effectiveness of a password of a given strength is strongly determined by the design and implementation of the factors (knowledge, ownership, inherence).The first factor is the main focus in this article.The only reason I can think is that someone, very very lazy, can decide to hack the check just to have an easier password to remember. I know that you cannot enforce a strong password on the client side and that if you are required to have a strong password in any circumstance, you have to do it on the server side.My point is: given that, to have an acceptable user experience, we have to do the check on the client side, there has to be a good reason, a real use case that creates a possible vulnerability to justify a duplication of the check on the server side.There are times you want forbid (blacklist) a password from usage.
Passwords are blacklisted using providers which can either an array or (flat-file) database (which you can update regularly).
A company that we have called to check security vulnerabilities pointed out that this is not enough because using some hacking a user can ignore the check and set a weak password.
I do not understand how this can be a security vulnerability.
The strength of a password is a function of length, complexity, and unpredictability.
Using strong passwords lowers overall risk of a security breach, but strong passwords do not replace the need for other effective security controls.
The rate at which an attacker can submit guessed passwords to the system is a key factor in determining system security.
