DETECTION OVERVIEW
Risk Factors
An attacker with network access to a RADIUS or Diameter server can easily attempt an automated brute force attack to guess passwords. If successful, the attacker can gain access to the network and launch attacks.
The system might change the risk score for this detection.
Category
Authentication, Authorization, and Accounting (AAA) is a security framework implemented in protocols such as RADIUS and Diameter. Before an attacker can gain access to devices, the attacker must first acquire valid credentials. A brute force attack is a method for guessing a weak user password. Brute force attacks can occur manually through trial and error or with automated tools.
Establish a throttling policy for failed attempts by implementing lockouts or timeouts
Delay Access-Reject response time to one second to increase attack difficulty
Implement multi-factor authentication
Enforce strong password policies

This analysis exposes the critical link between an organization's lack of internal visibility and the escalating cost of compromise, demanding an urgent re-evaluation of how core business assets are protected.
Learn why you need to be wary of the claims certain network detection and response providers make about their coverage against the MITRE ATT&CK framework.
Learn how NDR from RevealX helps security teams detect and investigate more adversary TTPs in the MITRE ATT&CK framework than rule-based tools.
