The purpose of this policy is to minimize the risk of loss or exposure of sensitive information maintained by MUSA Corporation and to reduce the risk of acquiring malware infections on computers on the MUSA. This sublayer decides among competing devices on who should gain the access to the media and send data. I System accounts and access are reviewed at least monthly to ensure that.

Obstacle to perfect channel utilization Finite propagation delay means that each users knowledge of the state of the system is imperfect and thus they can not perfectly schedule.

Access control is concerned with determining the allowed activities of legitimate users mediating every attempt by a user to access a resource in the system. Ii Following insertion into or connection with a non-EPA information system security personnel shall check EPA-owned USB removable media. I The removable media shall be encrypted unless the EPA Deputy Administrator or Chief Information Officer has identified all data on the device as non-sensitive in writing.

This sublayer which depends on a physical layer is a procedure controlled by the sender in which several devices on multidrop or bus networks compete to gain access to the medium for data transfer. And advance proposals of particular relevance to the Commissions Media Ownership priorities and rulemaking including. The CSO is the agency official with authority for.

MAC is responsible for the transmission of data packets to and from the network-interface card and to and from another remotely shared channel.
