Brute Force CLI Access
Identifying brute force Command Line Interface (CLI) access attempts, particularly through protocols like SSH (Secure Shell) and telnet, is crucial in safeguarding network security. Brute force attacks involve repeated attempts to guess login credentials and gain unauthorized access to systems. These attacks pose a significant threat as they can lead to compromised systems, data breaches, and unauthorized control over critical network resources. In the context of SSH and telnet, which are commonly used for secure administrative access to devices and servers, detecting brute force attempts is paramount. Early detection allows network administrators to implement countermeasures, such as blocking malicious IP addresses, enforcing strong password policies, or setting up additional authentication mechanisms, thereby mitigating potential security risks.
ElastiFlow provides a collection of anomaly detection jobs designed to identify brute force CLI access attempts through SSH and telnet including several targeted monitoring and analysis strategies.
