NSA Advises Regular Smartphone Reboots for Security

The National Security Agency (NSA) is urging iPhone and Android users to reboot their devices weekly to combat rising cybersecurity threats, particularly non-persistent malware that can be cleared with a restart. This advice, first introduced in a 2020 guide, is increasingly relevant as smartphones become key targets for cybercriminals. Rebooting not only mitigates risks from malware but also helps prevent spear phishing and zero-click exploits, which can compromise user data without interaction. The NSA emphasizes the importance of additional security practices, such as disabling unnecessary wireless connections, using strong authentication methods, and keeping software updated. Rebooting, while simple, functions as a necessary 'deep clean' for device memory, enhancing overall security. Responses to the NSA's guidance highlight both appreciation for raising awareness and criticism for the lack of detail regarding limitations of rebooting.
