Mobile Communications Best Practice Guidance

The Cybersecurity and Infrastructure Security Agency (CISA) has identified cyber espionage threats targeting sensitive mobile communications. In response, CISA released best practices to safeguard communications, focusing on highly targeted individuals like senior government officials. These recommendations include adopting end-to-end encryption, enabling phishing-resistant authentication, and transitioning away from vulnerable SMS-based MFA. By implementing these measures, organizations and individuals can significantly enhance their defense against malicious actors.
