The "Brute-Force" detection focuses on identifying attempts to gain unauthorized access to user accounts through repetitive guessing of passwords. Brute-force attacks involve trying numerous combinations of usernames and passwords until the correct one is found. This detection is crucial as successful brute-force attacks can lead to unauthorized access, data breaches, and further exploitation within the network.
Scenario 1: An attacker uses a tool to perform a brute-force attack on a company's VPN login portal. The tool tries various combinations of usernames and passwords until it successfully gains access to an account. This detection is triggered by the high number of failed login attempts from a single IP address.
Scenario 2: During a penetration test, the security team simulates a brute-force attack on several user accounts to test the organization's defenses. The detection is triggered, and the activity is verified as part of the scheduled assessment.
If this detection indicates a genuine threat, the organization faces significant risks:
Unauthorized access to user accounts can lead to further exploitation and data breaches.
Compromised accounts with elevated privileges can be used to gain further access within the network.
Repeated login attempts can overwhelm authentication systems, causing delays or outages.
A brute-force attack involves repeatedly trying various combinations of usernames and passwords until the correct one is found to gain unauthorized access to user accounts.
Common signs include numerous failed login attempts from a single IP address or user account, repeated login attempts with different usernames or passwords, and sudden spikes in authentication failures.
Yes, users forgetting their passwords, misconfigured applications, or scheduled security assessments can trigger this detection. It’s important to verify the context of the activity.
Vectra AI uses advanced AI algorithms to analyze authentication logs and identify patterns indicative of brute-force attacks, correlating these with other suspicious behaviors.
Implement strong password policies, use multi-factor authentication (MFA), monitor authentication logs, set up account lockout mechanisms, and regularly audit user activity and access controls.
Yes. Monitoring authentication logs for patterns of multiple failed login attempts, unusual login behaviors, and spikes in authentication failures can help detect brute-force attacks.
Successful brute-force attacks can lead to unauthorized access, account compromise, data breaches, and privilege escalation within the network.
Investigate the source of the login attempts, verify if they are legitimate, check for other signs of malicious activity, and take steps to secure affected accounts, such as resetting passwords and enabling MFA.
The primary risks are account compromise, privilege escalation, data breaches, operational disruptions, and compliance violations, which can lead to significant damage to the organization.
Tools like authentication log analyzers, Threat Detection and Response systems, and specialized monitoring solutions can help identify and verify brute-force attacks.
