Headline: NSA‘s 2024 Advice: Regular Reboots and Cybersecurity Best Practices
As cybersecurity threats continue to evolve, the National Security Agency (NSA) has issued timely advice for smartphone users in 2024: reboot your devices regularly. This guidance, reminiscent of a well-known comedic refrain, emphasizes the importance of maintaining security against sophisticated malware and spyware attacks. Recent updates from the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the U.K. Government Cyber Essentials scheme highlight the ongoing pursuit of enhanced digital security measures that all users should heed.
The Purpose Behind Regular Reboots
The NSA’s recent recommendations for iPhone and Android users include practical steps illustrated through an easy-to-understand infographic. The guidance addresses the dangers posed by zero-click exploits and emphasizes the necessity of regular smartphone reboots—specifically, powering off and on at least once a week.
While the phrase “turn it off and on again” might elicit laughs from fans of the British sitcom The IT Crowd, in cybersecurity, the phrase holds substantial merit. The NSA’s document categorizes what users should do—like employing strong passwords and keeping devices updated—and what to avoid—such as jailbreaking phones or clicking on unknown links.
Evaluating the Need for Rebooting
The question arises: do smartphone users truly need to reboot every week in 2024? While the short answer is no, experts suggest that regular reboots can benefit users in several ways.
Jake Moore, global cybersecurity evangelist with ESET, underscores the dual purposes of rebooting—a performance boost and a potential reduction in risks associated with non-persistent malware. “As long as people are regularly updating their devices when fresh operating system versions are released,” Moore states, “devices will remain healthy and protected.” Though rebooting isn’t an all-encompassing security strategy, it does mitigate certain vulnerabilities related to less sophisticated malware operations.
Zero-click malware, which has been a persistent challenge for both Apple and Android platforms, is typically addressed promptly by security updates once identified. However, rebooting regularly can reduce the chances of being victimized by such attacks. While there’s no definitive blanket rule, regular reboots may lessen overall vulnerability.
New Guidelines from CISA
In parallel with the NSA’s advice, CISA has introduced a new set of security requirements aiming to protect sensitive data from adversaries. The proposed guidelines focus primarily on entities engaged with sensitive information, particularly in transactions with partners potentially associated with cyber espionage or threat actors.
Dr. Marc Manzano, general manager of cybersecurity at SandboxAQ, asserts that these requirements signal crucial steps toward enhancing national cybersecurity. "These new guidelines, focusing on protecting sensitive information," say Manzano, "present opportunities for modern cryptography management systems.”
While primarily aimed at federal agencies, these recommendations also have broader implications for individual users, advocating for practices like:
- Updating devices promptly to fix known vulnerabilities
- Using two-factor authentication (2FA) on all accounts where applicable
- Ensuring passwords are at least 16 characters long
Cyber Essentials Scheme in the U.K.
The U.K. Government has also taken steps to strengthen cybersecurity through its Cyber Essentials scheme. This program sets out standards and controls organizations should adopt to mitigate common online threats. According to William Wright, CEO of Closed Door Security, accredited businesses are not only more aware of cyber risks but also feel more prepared to deal with them.
Statistics indicate that organizations adhering to the Cyber Essentials controls make 92% fewer insurance claims for cyberattacks than those without. “This evaluation demonstrates that Cyber Essentials offers significant security benefits to organizations,” Wright emphasizes.
Security Protocols and Business Partnerships
The Cyber Essentials certification relies on self-assessment, which can raise questions regarding the accuracy of reported security measures. While it significantly improves an organization’s cybersecurity resilience, experts urge businesses to consider achieving Cyber Essentials Plus certification and integrate other frameworks like NIST and ISO27001 for a more comprehensive approach.
By blending the practices recommended by the NSA and CISA with standards like Cyber Essentials, organizations can establish a robust security posture that reduces risks and enhances overall cybersecurity maturity.
