He continues by focusing on the different techniques and best practices that are available when troubleshooting NetFlow deployme
By COSMIC TRAVELER
Are you a network and security professional? If you are, then this book is for you! Author Omar Santos, has done an outstanding job of writing a book that gets you started with managing network security, install and configure network security features to provide additional visibility.
Author Santos, begins by providing an overview of Cisco Netflow and IPFIX. Then, the author covers the different Cisco NetFlow v9 export format and packet details, and includes a detailed comparison between NetFlow and IPFIX. He continues by providing an introduction to Cisco's Flexible NetFlow; as well as, covering the Flexible NetFlow components and fields. Then, the author provides details about the top commercial NetFlow analyzers. He then describes how NetFlow is used for big data analytics for cyber security, along with other network telemetry capabilities, such as firewall logs, syslog, SNMP, and authentication, authorization and accounting logs; in addition to logs from routers and switches, servers, and endpoint stations, among others. Next, the author provides detailed coverage of the Cisco Cyber Threat Defense Solution. He continues by focusing on the different techniques and best practices that are available when troubleshooting NetFlow deployments and configurations. Finally, the author covers several case studies and real life scenarios on how NetFlow is deployed in large enterprises and in small and medium-sized businesses.
This excellent book encompasses topics from an introductory level to advanced topics on Cisco Netflow, Cisco Cyber Threat Defense, and big data analytics tools, such as Logstash, Kibana, Elasticsearch, and many others. Also, this great book provides design and configuration guidance when deploying the Cisco Cyber Threat Defense Solution.

MUST HAVE RESOURCE FOR IT ADMINS!
By William W. Ellis
This is a great primer on Flexible NetFlow and IPFIX for those who have minimal experience with either technology! Omar Santos explains with clear language the basics for Cisco's NetFlow and how it relates to the open-standard IPFIX as well as clear examples for usage. I appreciated the way the book took me from a basic overview for the technologies into practical implementations on a variety of platforms, from Cisco IOS, to NX-IOS and even ASA and IOS-XR. This is a resource for every administrator who needs useful tools and understanding for Big Data Analytics including basic CyberSecurity and commonly available tools to collect and analyze the data. Introducing basic troubleshooting for several platforms was a true bonus! While it is not designed to be the ultimate source for everything with analytics, this book is a valuable addition to any administrator's library.

Good Book for Two Great Tools
By Bob Monroe
Imagine getting a book on some topic you love; say a book about “beer”. You relish the idea of reading all about this incredible beverage such as the different types of brew, its history, ingredients used, great breweries around the world, and so forth. Once the book arrives, the entire content is dedicated to one brand of beer and never once talks about how it tastes. Omar Santos pretty much accomplished this same feat with Network Security with Netflow and IPFIX .
First of all Dr. Santos has been quite busy pushing out books for Cisco. He just coauthored a book on security a few months back so he was probably very busy to put full effort into this book on Netflow. For those of you who aren’t familiar with Netwflow, it is probably one of the best network forensic tools ever created. That was the book I was expecting; one filled with all the different ways to use Netflow for forensic investigations and security of network traffic. Network forensic is very different from digital forensics because data is streaming across network devices at high speeds. Digital forensics usually involves locating static data off of evidence sitting right in front of you. They are two completely different fields with network forensics being incredibly advanced compared to the former.
Cisco created Netflow many years ago as a tool to collect data usage information for billing clients, locating bottlenecks, bandwidth scaling and basic tools normally associated with administrative tasks. Somewhere along the line somebody realized that Netflow can track much more useful information that can be used to recreate events, gather evidence of a crime, exonerate someone of a malicious act and help create logs for moving attacks to safer networks.
Netflow works on many devices besides Cisco so it is a tool that is usually installed as the network is created or when a savvy security administrator takes over a network. Basically, it is an essential tool in this line of work. Everyone thinks Wireshark is the bomb but Netflow works at a much higher level of traffic flow for filtering and collecting packets. I have nothing against Wireshark and use it on a regular basis yet Network is much more reasonable when you are dealing with terabytes of traffic per second on multiple connected devices.
Omar Santos does a good job of covering some of the open source tools like export protocols sFlow and Stream Control Transmission Protocol (SCTP). Both tools allow you to collect information about the data that crossed your network both inbound and outbound. As a security professional and a network forensic specialist, you rely on analytical tools to help you sort through all the hay to get to the needle.
As with all Cisco books, this one is very vendor oriented. Netflow is covered in all types of Cisco products ranging from ASA all the way to FireSIGHT Management Control Center. The different configurations are discussed in-depth which is nice if all your products are Cisco. Most organizations have a wide range of vendor products but at least you can use the configuration information as a map to help you understand your network devices. I was pretty impressed with the detailed information presented in the book but it kind of felt like a cheatsheet at certain points.
I love cheatsheets but I want them at the end of the book, not as the main content of a book. Mr. Santos covers a wide range of security uses for Netflow and IPFIX. I was expecting more information focused on the forensic abilities of these two incredible tools. There are multiple ways Omar shows the reader how to use the filtering aspects of these tools to make life easier. As with Wireshark, you gotta filter all that data or else you will lose your mind.
Both GUI and CLI are given equal discussion time in the book. We all know the real strength in any product is in the CLI, using switches and attributes to add power to commands. But we also know that sometimes we want to see what is happening to the thousands of packets we are examining.
Let’s face it: you would not but this book unless you knew the importance of these tools. The book does a great job of covering a wide range of the abilities of the tools. I was just expecting more specific details on network forensics. Because of my own expectations, I was a bit disappointed on the content. Maybe if I were a network guy, I’d be more impressed.
Netflow and IPFIX are two very different tools and have enormous capabilities if you know how to use them. Network Security with Netflow and IPFIX by Omar Santos is a good stab at all this complex information. These are not logging tools. If you are using them as logging tools than you are missing some serious heavy network help. If you want to learn about network forensics, this book is a good place to start.
