Zorluk: KolayPassword Security Policies, MFA, and Certificates

A network administrator is establishing password security policies on network devices to protect administrative logins from brute-force attacks. Which security policy control directly ensures that users choose strong passwords that resist dictionary attacks?

  1. Configuring minimum length and character complexity rulesCevap
  2. B
    Encrypting the entire authentication payload using RADIUS
  3. C
    Enabling sticky MAC address learning on switch access ports
  4. D
    Relying on the default implicit deny clause in access control lists

Cevap

Configuring minimum length and character complexity rules directly ensures users create resilient credentials that resist dictionary and brute-force guessing attacks.
Configuring minimum length and character complexity rules is the standard control for enforcing password strength. Requiring longer passwords containing a mix of upper and lower case letters, numbers, and symbols significantly increases entropy and mitigates dictionary or brute-force guessing attacks.

Adım Adım Çözüm

1
Identify the goal of the password security policy
The requirement is to prevent users from creating weak, easily guessed, or dictionary-vulnerable passwords.
Security policies dictate password composition rules prior to account creation or updates.
2
Evaluate the effect of password complexity and length enforcement
Requiring a combination of character types (uppercase, lowercase, numbers, symbols) along with sufficient length exponentially increases entropy.
Higher entropy prevents automated dictionary attacks from quickly discovering valid passwords.
