Because an intranet contains internal company information, security goes beyond the login screen. Access to records, tracking changes, and recovering data after unexpected events must be considered together.
A practical approach
Begin with strong authentication, least privilege, and regular access reviews. Apply additional controls to administrator accounts. If the intranet is accessible outside the corporate network, network boundaries, TLS configuration, and security updates become even more important.
What to consider in practice
Keep audit records for critical actions and protect their integrity. Test not only whether backups are taken but whether they can be restored. Plan file type, size, and malicious-content checks for upload features.
Key takeaway
Do not treat security as a one-time checklist. Without regular testing, incident-response planning, and clear responsibilities, technical safeguards can lose effectiveness over time.
