What to do

AI-suggested

  1. Monitor Mitel’s official security advisories and apply patches or updates immediately once they become available for the affected InAttend and CMG versions.
  2. Implement network segmentation to isolate Mitel communication systems from general enterprise networks and limit exposure to untrusted networks, especially the internet.
  3. Employ strict firewall rules to restrict access to BluStar components only to trusted IP addresses and internal users.
  4. Enable and enhance logging and monitoring on affected systems to detect unusual activities or unauthorized access attempts promptly.
  5. Conduct regular vulnerability assessments and penetration testing focused on Mitel infrastructure to identify potential exploitation attempts.
  6. Use intrusion detection/prevention systems (IDS/IPS) with updated signatures to detect exploitation attempts targeting this vulnerability.
  7. Develop and test incident response plans specifically addressing potential compromise of communication systems to minimize downtime and data loss.
  8. Educate IT and security teams about the vulnerability details and the importance of rapid response to any suspicious activity related to Mitel products.
