    – Use anti-malware software (*Malwarebytes/Avast/TrendMicro/etc) with real-time threat detection capabilities on all endpoints.
    – Require strong password policies, multi-factor authentication, and regular password changes for all accounts.
    – Regularly monitor endpoint activity and investigate any suspicious behavior immediately.

What is the Internet of Things (IoT) and how can I secure it in my home

    – Use a strong, unique password for each device and avoid using common phrases or easily guessable passwords.
    – Keep IoT software and firmware up to date with the latest security patches.
    – Segregate IoT devices from other networks and devices to prevent them from becoming entry points into your main network.
    – Disable unnecessary services, features, and functions on IoT devices to reduce their attack surface.
