Reporting IDS alerts of malicious transactions to interested parties does not ensure the ongoing security of an Intrusion Detection System (IDS). While it is important for situational awareness and incident response, it does not directly contribute to the security and maintenance of the IDS itself. Ensuring ongoing security of an IDS involves activities such as encrypting IDS management communications and creating unique user and administrator accounts for every IDS system, which help protect the IDS from being compromised. References include NIST SP 800-94, which provides guidelines for securing IDS systems.
