Failed Log-in Restrictions and Mobile Access Control for A+
Short answer
Limiting failed log-in attempts reduces the effectiveness of brute-force attacks. Common responses include temporary lockouts, increasing delays between attempts, or wiping the device after a threshold. Technicians must weigh data sensitivity, user convenience, and backup presence before enabling destructive policies. For managed devices, these controls may be set remotely via MDM; for BYOD, users may resist destructive defaults.
Why it appears on the exam
- Given a device type and ownership model (corporate vs BYOD) and a sensitivity level, select appropriate failed log-in policy and justify. - Identify technician steps to recommend or change wipe-after-failed-attempts setting for a managed device.
Key concepts
Concept 1
Required terms
failed log-in restriction: A policy that limits attempts to authenticate before imposing a penalty (lockout or wipe). lockout: A temporary prevention of further authentication attempts after consecutive failures. wipe-after-failed-attempts: A configuration that triggers a full device wipe after a set number of failed authentication attempts.
Example
Enabling a 10-attempt wipe for highly sensitive corporate devices, with prior automatic backup scheduled nightly.
Concept 2
How Failed Log-in Restrictions and Mobile Access Control works
Limiting failed log-in attempts reduces the effectiveness of brute-force attacks. Common responses include temporary lockouts, increasing delays between attempts, or wiping the device after a threshold. Technicians must weigh data sensitivity, user convenience, and backup presence before enabling destructive policies. For managed devices, these controls may be set remotely via MDM; for BYOD, users may resist destructive defaults.
Example
Choosing temporary lockout (5 minutes after 5 failures) on consumer devices to avoid accidental wipe by children.
Concept 3
Common confusion
- "Lockout is the same as wipe" - lockout is usually temporary and safe; wipe is destructive and should be used cautiously. - "More strict is always better" - overly strict settings can lead to accidental data loss and support calls; consider backup and supportability.
Example
Enabling a 10-attempt wipe for highly sensitive corporate devices, with prior automatic backup scheduled nightly.
