As time protocols are becoming increasingly common and widely deployed, concern about the resulting exposure to various security threats is increasing. If a time protocol is compromised, the applications it serves are prone to a range of possible attacks including Denial of Service (DoS) or incorrect behavior.

                 Security Requirements of Time Protocols                       in Packet Switched Networks


   As time and frequency distribution protocols are becoming    increasingly common and widely deployed, concern about their exposure    to various security threats is increasing.  This document defines a    set of security requirements for time protocols, focusing on the    Precision Time Protocol (PTP) and the Network Time Protocol (NTP).    This document also discusses the security impacts of time protocol    practices, the performance implications of external security    practices on time protocols, and the dependencies between other    security services and time synchronization.
