Set Delay between Failed Login Attempts to 4

MittelStufe 1Automatisiertsolaris

Beschreibung

The SLEEPTIME variable in the /etc/default/login file controls the number of seconds to wait before printing the "login incorrect" message when a bad password is provided. The default value for SLEEPTIME is 4 seconds. As an immediate return of an error message, coupled with the capability to try again may facilitate automatic and rapid-fire brute-force password attacks by a malicious user, this delay time should be set as appropriate to the needs of the user. Audit: SLEEPTIME must be 4 or left commented out (default 4).
