Definition of Brute Force Attack

A brute force attack is an assault method carried out by trying various password combinations until the correct password is found. Attackers will try passwords with various combinations, such as uppercase and lowercase letters, numbers, and symbols. This method takes a long time but is quite effective if the attacker knows the type of password used by the target system or account.

Types of Brute Force Attack

Here are the types of brute force attacks commonly used by attackers:

  • Brute Force Attack on Login Forms: This type is the most frequently occurring type of brute force attack. Attackers will attempt various password combinations on login forms, such as those on websites or applications.
  • Brute Force Attack on SSH: This is a method of attacking systems that use Secure Shell (SSH) as a network protocol. Attackers will try various password combinations to breach systems using SSH.
  • Brute Force Attack on FTP: This method attacks systems using File Transfer Protocol (FTP) as a network protocol. Attackers will attempt various password combinations to breach systems using FTP.

Steps to Prevent Brute Force Attack

Here are some steps you can take to prevent brute force attacks:

  • Use Strong Passwords: Ensure to use strong and unpredictable passwords. A strong password should consist of a combination of uppercase and lowercase letters, numbers, and symbols.
  • Limit Failed Login Attempts: Set a limit for failed login attempts to prevent attackers from performing brute force attacks by repeatedly trying passwords. After reaching the limit of failed attempts, the account will be locked for some time.
  • Use Two-Factor Authentication: Adding a two-factor authentication method, such as SMS verification or an authentication app, will increase account security and strengthen protection against brute force attacks.
  • Use Cloud-Based Security Technology: Utilizing cloud-based security technology can help prevent brute force attacks by analyzing and blocking attacks before they reach your system.
  • Regularly Update Systems and Applications: Regularly update systems and applications to ensure they have the latest security and fix vulnerabilities that could be exploited by attackers.



Brute force attacks are one of the major threats to information security today. Therefore, it is crucial for users to know and understand about brute force attacks and how to prevent them. From the explanation above, it can be seen that several steps can be taken to prevent these attacks, such as using strong passwords, limiting failed login attempts, adding two-factor authentication methods, utilizing cloud-based security technology, and regularly updating systems and applications.
