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
