 With the recent cybersecurity breach at the Office of Personnel Management, now more than ever, service members are reminded of Operation Security or OPSEC. Even if a document is unclassified, that does not mean it's unimportant. Documents that may seem harmless today could be critical in the future. It is every service member's duty to know their command's critical information and stay up to date because as the mission changes, so does the critical information of the command. There can be several indicators that may alert the enemy to future operations, such as a ship taking on a large amount of fresh fruit and vegetables could indicate that the ship will be getting underway soon. Not every indicator can be protected, but we must remain vigilant and protect as much information as possible. For more information about OPSEC, visit the Naval Operations Security Facebook page.
