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

DNS Defending the Domain Name System provides tactics on how to protect a Domain Name System (DNS) framework by exploring common DNS vulnerabilities, studying different attack vectors, and providing necessary information for securing DNS infrastructure. The book is a timely reference as DNS is an integral part of the Internet that is involved in almost every attack against a network. The book focuses entirely on the security aspects of DNS, covering common attacks against DNS servers and the protocol itself, as well as ways to use DNS to turn the tables on the attackers and stop an incident before it even starts.

The biggest online threat to businesses and consumers today is ransomware, a category of malware that can encrypt your computer files until you pay a ransom to unlock them. With this practical book, you'll learn how easily ransomware infects your system and what steps you can take to stop the attack before it sets foot in the network.
