Brute force network attacks are a type of cyberattack in which an attacker attempts to gain unauthorized access to a computer system, network, or application by systematically trying all possible combinations of usernames and passwords until the correct combination is found.
These attacks are characterized by their persistence and their reliance on sheer computational power to guess login credentials.
Attackers may use techniques to avoid detection, such as slowing down the login attempts, using different IP addresses, or employing proxy servers to hide their origin.

Defence against brute force attacks
Defending against brute force attacks is crucial for maintaining the security of your systems and data.
Strategies include:
Strong Passwords and 2FA: Enforce strong password policies and enable two-factor authentication (2FA).
Account Lockout: Implement account lockout after a set number of failed login attempts.
Rate Limiting: Limit the number of login attempts from a single source within a timeframe.
Intrusion Detection: Use intrusion detection systems to monitor and alert on suspicious login patterns.
Firewalls: Configure firewalls to block traffic from known malicious sources.
CAPTCHA: Implement CAPTCHA challenges on login forms to deter automated attacks.
User Education: Educate users on password security and best practices.
Regular Updates: Keep all software up to date with security patches.
Security Audits: Conduct security audits and penetration testing.
The use of multi-factor authentication can help prevent brute force attacks by adding an extra layer of .
Brute force attacks can be mitigated by implementing password policies.
