Recommendations to Defence to reduce Denial of Service risks:

Implement rate limiting and traffic filtering to mitigate the impact of incoming malicious traffic.
Check with your IT service provider that the resilience of its systems against such attack was tested.
Regularly monitor network traffic and set up alerting for unusual patterns or spikes.
Diversify your server locations and use failover systems to ensure service availability in case of an attack.
Establish an incident response plan to quickly mitigate and recover from DoS attacks.
