OSI LAYER 7 // Application Layer

Brute-Force Attack

A brute-force attack repeatedly guesses credentials or secrets until a valid value is found.

01 // HOW IT WORKS

Mechanism

An attacker automates many authentication attempts against an account, service, or protected resource. Defensive analysis focuses on rate, distribution, source reputation, and successful attempts after failures.

02 // DETECTION

Indicators to watch

High failed-login rates, repeated attempts against one or many accounts, distributed source addresses, lockouts, and successful logins following bursts of failures.

04 // PREVENTION

Defensive controls

Use MFA, rate limiting, progressive delays, account protection, password policies, breached-password screening, bot detection, and centralized authentication monitoring.

05 // SECURITY TOOL

Recommended security control

SIEM correlation + identity protection

Use synthetic accounts in a lab; do not perform credential guessing against real accounts.
