Technical Mitigations AI-generated
• Implement a robust security training program for employees, such as the one accelerated by Xolis after their data breach.
• Regularly monitor system logs to detect and alert on potential threats, with a focus on increasing detection rates (e.g., 54% of successful attacks detected).
• Utilize breach and attack simulation tests, like those described in the Picus whitepaper, to identify vulnerabilities in SIEM and EDR rules.
