Implement Basic Security Controls

Start by enforcing strong authentication: set complex password policies, require multi-factor authentication where possible, and disable default accounts. Configure account lockout settings to prevent brute-force attempts, and ensure password rotation and history rules are enforced through local or domain policies.

Next, configure system-level protections: enable the firewall with restricted inbound rules by default, apply least-privilege principles for user and service accounts, and disable unnecessary services and ports. Install and update antivirus or endpoint protection tools to detect and block known threats.

Finally, harden system configurations: remove or disable unused features and applications, enable logging of security events, configure automatic security updates, and ensure audit policies capture authentication and privilege changes. These measures create layers of defense and aid early detection of anomalies.
