NTP Security

Learn the risks associated with Network Time Protocol (NTP) security and how to minimize those risks while deploying and managing the protocol. You will be able to reduce the disruption of communication between servers on the network and the risk that the entire network will be taken offline.

NTP Security: A Quick-Start Guide provides an understanding of how NTP is critical to modern networks and how it can be exploited. You will understand how an attacker can wreak havoc on an insecure network and guidance is provided to help you manage your system and make it more secure.

What You Will Learn:

• Understand the vulnerabilities, flaws, and risks associated with the Network Time protocol (NTP)
• Analyze NTP traffic and configure NTP on servers and workstations in the network in a more secure manner

• Use practical solutions to secure NTP and build a robust infrastructure, such as bringing more capability inside the network and creating a smaller attack surface

• Determine the alternatives to NTP, including how to synchronize network clocks in other ways Who This Book Is For:

  System administrators, network engineers, and security analysts

  Network Time Protocol (NTP) attacks are a growing threat and security teams will have the information they need to be ahead of the curve Practical guidance is given to configure a more secure NTP across multiple platforms Alternatives to NTP are discussed, including finding a better, more secure, solution to time synchronization
