Password Attacks Explained: Brute Force, Phishing, and Beyond

Learn about common password attack methods and how to protect your organisation against them for Cyber Essentials compliance.

Understanding Password Attacks

Password attacks are among the most common methods used by cybercriminals to gain unauthorised access to systems. Understanding these attack methods is crucial for implementing effective defences.

Common Password Attack Methods

Brute Force Attacks

Brute force attacks involve systematically trying every possible password combination until the correct one is found. While computationally intensive, they can be effective against weak passwords.

Dictionary Attacks

Dictionary attacks use lists of common passwords, words, and phrases. These attacks are faster than brute force because they target passwords people actually use.

Credential Stuffing

Attackers use previously breached username/password combinations to attempt login on other services, exploiting password reuse habits.

Phishing Attacks

Phishing involves tricking users into entering their credentials on fake websites or forms that appear legitimate.

Defence Strategies

Protection Measures

  • Strong, unique passwords for each account
  • Multi-factor authentication (MFA)
  • Account lockout policies
  • User education and awareness training
  • Password managers

Cyber Essentials Requirements

For Cyber Essentials certification, implement robust password security measures:

  • Strong password policies: Enforce minimum length and complexity requirements
  • Account protection: Implement lockout mechanisms against brute force
  • Multi-factor authentication: Use MFA for privileged accounts
  • User training: Educate staff about password security and phishing threats
