Review the Trend Deep Security server configuration to ensure the limit of three consecutive invalid logon attempts by a user during a 15-minute time period is enforced.

Verify the number of failed logon attempts. Go to Administration >> System Settings >> Security >> User Security >> Number of incorrect sign-in attempts allowed (before lock out): 3
