NSA recommends restarting phone once a week

National Security Agency (NSA) has reportedly advised restarting phones once a week to improve security. The advisory from NSA to all the Android and iPhone devices users to restart their devices once every few days. Regularly rebooting devices helps clear temporary files and caches, which can improve performance and reduce the risk of certain types of cyber threats, such as malware or software vulnerabilities.

Restarting your phone periodically can also ensure that any updates or patches released by the manufacturer are applied, keeping your device up-to-date and secure. It can clear temporary files and memory leaks that might be exploited by certain vulnerabilities. At the same time, some malware or exploits might rely on staying in memory to function. A restart disrupts them.

Forbes reports that, an NSA document from years ago, recently made public, offers advice on how to protect smartphones from threat actors and that occasionally restarting devices can assist in getting rid of malware and zero-day exploits that may be installed. It's important to remember that a weekly reboot is not a foolproof security measure. It might help against some specific attack types, but it won't protect against all threats.

it's also essential to follow other cybersecurity practices, such as using strong and unique passwords, keeping software and apps updated, being cautious of suspicious links and downloads, and using security features like encryption and two-factor authentication when available.
