Logs are the audit trail of everything that happens in your environment. Without logs, you cannot detect attacks in progress, investigate past incidents, prove compliance to regulators, or support insurance claims. The average attacker dwells inside a network for 197 days before being detected. Without centralised logging and monitoring, that attacker is invisible the entire time. Under CSA 2024 and NACSA guidelines, CNII-adjacent organisations must maintain security logs for a minimum of 90 days.
