The National Security Agency (NSA) has recommended that all iPhone and Android users restart their devices at least once a week. These guidelines are part of a broader set of best practices to improve mobile device security and protect users from potential cyber threats.
The advice, detailed in a document issued by the NSA, underlines the importance of regularly restarting devices as a simple but effective measure to limit the risk of cyber attacks. The NSA’s guidance comes amid growing concerns about the increasing sophistication of cyber threats targeting mobile devices.
The reason behind weekly reboots
According to the NSA, restarting mobile devices can help disrupt the operation of malware and other malicious software that may have infiltrated the system.
Many types of malware are designed to persist in the device’s memory, and a restart can effectively clear this memory, neutralizing the threat.
The NSA stated in the advisory: “Regularly restarting your mobile device can ensure that any malicious code running in the background is terminated. This simple action can significantly reduce the risk of persistent malware infections.”

The advisory also emphasizes that while a restart is not a foolproof solution, it is a valuable part of a comprehensive security strategy.
The NSA recommends combining regular reboots with other best practices, such as keeping the device’s operating system and applications up to date, using strong passwords, and enabling multi-factor authentication.
In addition to the weekly reboot recommendation, the NSA document outlines several other best practices for mobile device security:
- Update software regularly: Ensure that the device operating system and all installed applications are kept up to date with the latest security patches and updates.
- Use strong authentication: Enable multi-factor authentication (MFA) to add an extra layer of security beyond just a password.
- Be careful with public Wi-Fi: Avoid using public Wi-Fi networks for sensitive transactions. If necessary, use a virtual private network (VPN) to secure the connection.
- Install apps from trusted sources: To reduce the risk of installing malicious software, download and install applications only from official app stores, such as the Apple App Store or Google Play Store.
- Check app permissions regularly: Regularly review the permissions granted to installed applications and revoke any permissions that seem unnecessary or overly intrusive.
The NSA’s advisory comes at a time when cyber threats targeting mobile devices are becoming increasingly common and sophisticated. Cybercriminals are constantly developing new methods to exploit vulnerabilities in mobile operating systems and applications, making it more important than ever for users to implement robust security practices.
Recent reports indicate an increase in mobile malware attacks, phishing attempts and other forms of cybercrime targeting smartphone users. These threats can have significant consequences, including data breaches, financial losses and compromised personal information.
The NSA’s recommendation to restart mobile devices once a week is a timely reminder of the importance of proactive security measures in the digital age.
By incorporating regular restarts into their routine and following other best practices, iPhone and Android users can better protect themselves against the ever-evolving cyber threat landscape.
