Approved for public release, distribution is unlimited / Recent advances in information technology communications have brought about increases in bandwidth and processing speeds to encourage the growth of Internet Protocol Telephony (IPT), a method of transmitting voice conversations over data networks. Many organizations are replacing portions of their traditional phone systems to gain the benefits of cost savings and enhanced feature sets through the use of IPT. The Coast Guard has an interest in exploiting this technology, and has taken its first steps by implementing IPT at Headquarters Support Command in Washington D.C. This thesis investigates the successful implementation practices and security policies of commercial, educational, and government organizations in order to create recommendations for IPT security policies and implementation practices relevant to the Coast Guard. It includes the discussion of the public switched telephone network, an overview of IPT, IPT security issues, the safeguards available to counter security threats, the tradeoffs (e.g., voice quality, cost) required to mitigate security risks, and current IPT security policy and implementation guidance. It is supported by the study and analysis of the IPT system at Coast Guard Headquarters. The Coast Guard gains an understanding of the advantages, limitations, and security issues that it will face as it considers further implementation of IPT. / Lieutenant, United States Coast Guard

All levels of society, individuals, businesses and governments, must be involved in order to reverse the unsustainable path that society is currently on. Though much has been written about what needs to be done, there is much less literature on how to do it. This study attempts to start filling this gap. This paper is focused on the Vision 2050 report which acknowledges the role businesses have in moving society towards sustainability. The Vision 2050 report which was released by the World Business Council for Sustainable Development explores the current reality business is facing and the opportunities that are available for them to incorporate sustainability into the mainstream of their business. The study examines how businesses can begin to integrate sustainability into their company’s operations and services, using the report for inspiration and the Framework for Strategic Sustainable Development as guidance. A suggested approach is presented in the form of an implementation guide, which can be used by business to help them navigate their organization, collaborate with others and to develop an action plan as they work to integrating sustainability into their operations
