Maritime security operations (MSO) are the actions of modern naval forces to "combat sea–based terrorism and other illegal activities, such as hijacking, piracy, and slavery, also known as human trafficking." Ships assigned to such operations may also assist seafaring vessels in distress. These activities are part of an overall category of activities which fall short of open warfare called military operations other than war (MOOTW). MSO also involve the marine environmental protection, creating a safer and clean environment. The United States Coast Guard, along with several other agencies such as Navy, Maritime Administration, the Department of Transportation, the Environmental Protection Agency, and the Federal Maritime Commission are American agencies that have a role in the regulation of U.S ports. Their mission is to create a safer and reliable international ocean transportation system, to protect the public from any unfair and deceiving practice.
