Step 1: Installing a Server Activity Monitoring Program
To set up automatic alerts for suspicious activity on the server, you need to install a special program to monitor activity. One such popular tool is Snort — an open-source intrusion detection system.
Step 2: Configuring Snort
After installing Snort, you need to configure it. This includes defining rules for detecting suspicious activity, configuring alerts, and setting up notifications about potential threats.
Step 3: Setting Up Alerts for Suspicious Activity
To set up automatic alerts for suspicious activity on the server, you need to specify alert parameters in the Snort configuration file. This includes specifying the email address or phone number to which notifications will be sent.
alert email admin@example.com any any -> any any (msg: "Suspicious activity detected";)
Step 4: Testing the Alert System
After completing all the previous steps, you need to test the alert system to ensure it is working correctly. To do this, you can play the role of an attacker and try to perform suspicious activities on the server.
Step 5: Additional Security Measures
To ensure more reliable server protection, it is recommended to take additional security measures, such as installing a firewall, regularly updating software, and monitoring user activity on the server.
These steps will help detect and prevent suspicious activity on the server, providing a higher level of security and protection against threats.
