AI-suggested

1. Monitor Fortinet advisories closely for official patches or updates addressing CVE-2024-35280 and apply them promptly upon release. 2. Implement strict input validation and output encoding on any custom integrations or web interfaces interacting with FortiDeceptor recovery endpoints to reduce XSS risk. 3. Deploy Web Application Firewalls (WAFs) with rules designed to detect and block reflected XSS attack patterns targeting FortiDeceptor URLs. 4. Educate users and administrators about the risks of clicking unsolicited or suspicious links, especially those purporting to be related to FortiDeceptor management. 5. Restrict access to FortiDeceptor web interfaces to trusted networks and VPNs to reduce exposure to external attackers. 6. Enable multi-factor authentication (MFA) for FortiDeceptor management accounts to mitigate session hijacking risks. 7. Regularly audit FortiDeceptor logs and monitor for anomalous web requests or unusual user activity indicative of exploitation attempts. 8. Consider network segmentation to isolate deception infrastructure from general user environments, limiting the impact of any compromise. 9. If possible, disable or limit the use of recovery endpoints until patches are available or risk is mitigated. 10. Maintain an incident response plan that includes scenarios involving compromise of deception technology components.
