 Cyber attacks, intrusions, attempts, and probes are happening every hour, every minute of every day. The threat is real and comes from a variety of sources, including nation-states, profit-motivated criminals, and ideologically motivated hackers, extremists, and terrorists. Our Navy networks, our systems, and you are under attack. The Navy must operate its IT networks like a warfighting platform. With the increase of cyber threats across the globe, the Navy is hardening another weapon system essential for effective operations, its networks, both a float and a shore. NMCI serves 700,000 users in 2,500 locations that send more than 33 million weekly email messages. NMCI prevents more than 231 million unauthorized intrusion attempts per month. It blocks 3.5 million spam messages per month. The Cane's tactical afloat network serves as the cyber platform for more than 200 applications in connected systems, including data, transport, systems management, voice, and video. However, humans still remain the weakest link in cybersecurity. Successfully defeating our adversaries in the cyber realm is an all-hands effort. Installations in modernization of C4I systems, security upgrades, and patches, and proper network configurations are important pieces to staying safe. But, ultimately, you are the first and most important line of defense. Follow the guidance provided to you, stop and think before you click, and always think about cybersecurity before exposing the network via spam and phishing attempts. Cybersecurity demands constant vigilance. You can make all the difference by working together to keep our Navy network safe and secure.
