6. Encrypt Data for Enhanced Privacy

Why It Matters: Encryption secures data as it moves between devices, preventing unauthorized access and data interception.

Best Practices:
– Device-Level Encryption: Choose devices that support data encryption for both stored and transmitted data.
– Router-Level Encryption: Enable encryption features on your router to protect all data passing through the network.
– End-to-End Encryption for Communications: Ensure that devices and apps handling sensitive information, such as security cameras or door locks, use end-to-end encryption.

7. Monitor and Limit Device Permissions

Why It Matters: Many smart devices request permissions to access different types of data or control features, sometimes more than necessary. Limiting these permissions reduces the risk of unauthorized access.

Best Practices:
– Review Permissions During Setup: When setting up new devices, carefully review requested permissions and disable any that are unnecessary for the device’s functionality.
– Limit Data Sharing: Disable data-sharing features on devices that don’t need to communicate with external networks.
– Regularly Check Permissions: Periodically review permissions to ensure they align with your current security needs and remove any unnecessary ones.

8. Secure Physical Access to Devices

Why It Matters: Physical security is often overlooked in smart homes. Devices in accessible locations can be tampered with, compromising the security of your entire network.

Best Practices:
– Secure Locations for Critical Devices: Place routers and other critical devices in secure locations within the home to prevent unauthorized access.
