=== Password Policies
|
|
|
|
Each new realm created has no password policies associated with it. This means users can have as short, as long, as complex,
|
|
as insecure a password as they want. This is great for development or if you are just learning and playing around with {{book.project.name}},
|
|
but pretty much unacceptable in production environment. {{book.project.name}} has a rich set of password policies you can enable
|
|
through the Admin Console.
|
|
|
|
Click on the `Authentication` left menu item and go to the `Password Policy` tab. Choose the policy you want to add in the
|
|
right side drop down list box. This will add the policy in the table on the screen. Choose the parameters for the policy.
|
|
Hit the `Save` button to store your changes.
|
|
|
|
.Password Policy
|

|
|
|
|
After saving your policy, user registration and the Update Password required action will enforce your new policy. Here's
|
|
what it would look like if the user failed the policy check:
|
|
|
|
.Failed Password Policy
|
|
image:../../{{book.images}}/failed-password-policy.png[]
|
|
|
|
|
|
Unfortunately,
|
|
users are not required to update their password if the password policy changes and there is no nice way of triggering an
|
|
Update Password required action other than setting it manually for every user. This is scheduled as a future enhancement.
|
|
|
|
==== Password Policy Types
|
|
|
|
Here's an explanation of each policy type:
|
|
|
|
{% if book.community %}
|
|
HashAlgorithm::
|
|
Passwords are not stored as clear text. Instead they are hashed using standard hashing algorithms before they are stored or validated.
|
|
The only built-in and default algorithm available is PBKDF2. See the link:{{book.project.doc_base_url}}{{book.project.doc_info_version_url}}{{book.developerguide.link}}[{{book.developerguide.name}}]
|
|
on how to plug in your own algorithm. Note that if you do change the algorithm, password hashes will not change in storage until
|
|
the next time the user logs in.
|
|
{% endif %}
|
|
{% if book.product %}
|
|
Hashing Algorithm::
|
|
Passwords are not stored as clear text. Instead they are hashed using standard hashing algorithms before they are stored or validated.
|
|
The only currently supported algorithm is PBKDF2.
|
|
{% endif %}
|
|
Hashing Iterations::
|
|
This value specifies the number of times a password will be hashed before it is stored or verified. The default value is 20,000.
|
|
This hashing is done in the rare case that a hacker gets access to your password database. Once they have the database
|
|
they can reverse engineer user passwords.
|
|
The industry recommended value for this parameter changes every year as CPU power improves. The current recommended value
|
|
is 20,000. Yes, 20,000 iterations! This is a very intensive CPU operation and with this high of a setting your servers
|
|
are going to be spending most of their CPU power on hashing. You'll have to weigh what is more important to you. Performance
|
|
or protecting your passwords stores. There may be more cost effective ways of protecting your password stores.
|
|
Digits::
|
|
How many digits are required to be in the password string?
|
|
Lowercase Characters::
|
|
How many lower case letters are required to be in the password string?
|
|
Uppercase Characters::
|
|
How many upper case letters are required to be in the password string?
|
|
Special Characters::
|
|
How many special characters like '?!#%$' are required to be in the password string?
|
|
Not Username::
|
|
When set, password is not allowed to be the same as the username.
|
|
Regular Expression::
|
|
Define a Perl regular expression pattern that passwords must match.
|
|
Expire Password::
|
|
How many days is a password valid for? After the number of days has expired, the user will be required to change their password.
|
|
Not Recently Used::
|
|
This policy saves a history of previous passwords. The number of old passwords stored is configurable. When a user changes their password
|
|
they will not be able to re-use any password stored in history.
