Login Security and Behavior

Password policy can be defined on the System > Users > Local Users > Password Policy page to control and place restrictions on user login passwords (see Local Users). In addition to this, you can define further login behavior settings to provide a greater degree of control and security awareness for the users of your system. The “Login and Security Settings” section of the System > Global Settings page provides a number of configuration settings split broadly into two themes:

UI Screen Banners

Should you need to provide your users with a suitable message or reminder upon using the system, define these here.

Setting

Description

login_banner

A banner text message to be displayed to anyone who attempts to log in to the Admin UI or Traffic Manager SSH command line.

banner_accept

Whether the user is required to explicitly acknowledge and agree to the login_banner text prior to logging into the Admin UI. A check box is added to the login page for this purpose.

uipage_banner

This is a text message that will be displayed at the top and bottom of each page of the Admin UI.

Login Controls

You can place controls on the number of login attempts available to users, and the consequences of breaching this.

Setting

Description

max_login_attempts

The number of login failures permitted before a user account is suspended. A value of 0 disables this feature. Default: 0.

The user account is reactivated after the delay set in max_login_suspension_time; however, it can be reactivated sooner from the System > Users > Local Users > Edit page or the System > Users > Suspended Users page (see Suspended Users).

Ivanti recommends exercising caution when using a login attempt limit with password based authentication. Always use additional security measures such as a firewall or unique user naming convention to avoid rendering your Traffic Manager potentially inaccessible through a Denial-of-Service attack on your administrative user logins.

max_login_external

Specifies whether externally authenticated (LDAP, RADIUS or TACACS+) users should be suspended after max_login_attempts login failures.

max_login_suspension_time

The length of time for which a user account is suspended after max_login_attempts login failures.

login_delay

The delay after a failed login before another login attempt can be made. Default: 4.
