Kevin Mitnick's exploits as a cyber-desperado and fugitive form oneof the most exhaustive FBI manhunts in history and have spawneddozens of articles, books, films, and documentaries. Since hisrelease from federal prison, in 1998, Mitnick has turned his lifearound and established himself as one of the most sought-aftercomputer security experts worldwide. Now, in The Art of Deception,the world's most notorious hacker gives new meaning to the oldadage, "It takes a thief to catch a thief."
Focusing on the human factors involved with information security,Mitnick explains why all the firewalls and encryption protocols inthe world will never be enough to stop a savvy grifter intent onrifling a corporate database or an irate employee determined tocrash a system. With the help of many fascinating true stories ofsuccessful attacks on business and government, he illustrates justhow susceptible even the most locked-down information systems areto a slick con artist impersonating an IRS agent. Narrating fromthe points of view of both the attacker and the victims, heexplains why each attack was so successful and how it could havebeen prevented in an engaging and highly readable style reminiscentof a true-crime novel. And, perhaps most importantly, Mitnickoffers advice for preventing these types of social engineeringhacks through security protocols, training programs, and manualsthat address the human element of security.

The Go programming language, often referred to as Golang (albeit wrongly), is really making strides, with some masterclass developments, architected by the greatest programming minds. Tobias Lutke, CEO of Shopify, recently quoted as saying “Go will be the server language of the future”, powerful words, with much ambition. Go programmers are in high demand, but more controversially, Go takes the stage, where C and Unix programmers previously led the way.
The growth of the Go language has seen it become the means by which systems, networking, web, and cloud applications are implemented. Comfortable with syntax, you’ll benefit by mastering the use of the libraries and utilise its features, speed, and efficiency, for which the Go ecology is justly famous.
You already know a little Go syntax and you’ve written some small projects, most Go programmers face the difficulty of having to integrate their Golang skills with production code. Typical introductions to Go programming, often stop short of this transition, the author continue on, showing you just how to tackle this.
Offering a compendium of Go, the book begins with an account of how Go has been implemented, also, the reader will benefit from a dedicated chapter, an in-depth account of concurrency, systems and network programming, imperative for modern-day native cloud development.What you will learn Understand the design choices of Golang syntax Know enough Go internals to be able to optimize Golang code Appreciate concurrency models available in Golang Understand the interplay of systems and networking code Write server-level code that plays well in all environments Understand the context and appropriate use of Go data types and data structuresWho this book is for
This book is for Golang programmers. You should have previously read an introductory book on Go, or to have worked through the Tour of Go or an equivalent online course. This book will definitely help to remember the basic concepts of concurrency, but network programming will be explained. A certain amount of previous coding and production experience would be helpful.

Telecom 101 is composed of three parts: Fundamentals of Telecommunications, Telecommunications Technologies, and the IP Telecommunications Network.
PART I FUNDAMENTALS OF TELECOMMUNICATIONS
2 FUNDAMENTALS OF TELEPHONY
4 THE TELECOMMUNICATIONS INDUSTRY
We begin with the fundamentals of telephony and the telephone network – the basis for understanding everything else.
First is the Public Switched Telephone Network (PSTN): loops and trunks, circuit-switching, analog, the voiceband and Plain Ordinary Telephone Service (POTS). Plus, new for the fourth edition: Voice over IP (VoIP) is now part of the fundamentals.
Next is switching, starting with traditional telephone switches: Centrex, PBX and PBX trunks, and how that relates to the newer ideas of softswitches, Hosted PBX and SIP trunking.
This part is completed with a chapter on the telecommunications business: Local Exchange Carriers and Inter-Exchange Carriers, ILECs and CLECs, the main players and how carriers interconnect.
PART II TELECOMMUNICATIONS TECHNOLOGIES
6 TRANSMISSION SYSTEMS
7 THE NETWORK CLOUD AND SERVICE PROVISIONING
8 FIBER OPTICS
9 DSL AND CABLE MODEMS: LAST MILE ON COPPER
The second part is devoted to telecommunications technologies: the actual methods used to implement circuits and services.
We begin with digital: what digital is, how voice and video are digitized, and how digitized information is actually transmitted.
The next chapter is transmission systems: the high-capacity systems developed to carry many users’ traffic. This starts with the installed base of channelized systems, the hierarchy of DS0, DS1 and DS3 rates and an overview of T1, T3, SONET and ISDN.
Then our attention turns to the new generation packetized systems, introducing the concepts of overbooking and bandwidth on demand instead of channels, how this is implemented with frames and packets, coexistence and transition from channels to packets.
Then we understand the “Network Cloud”, how services are actually implemented, the three basic types of services and the equipment used for each.
Completing this part are chapters on the technologies used to implement the network:
Fiber Optics, including fundamentals of fiber, wave-division multiplexing, the network core, Metropolitan Area Networks, Passive Optical Networks and fiber to the premise.
Last Mile on Copper: DSL and Cable Modems, including fundamentals of modems, DSLAMs, VDSL, broadband and cable modems.
Wireless, concentrating on mobile communications: cellular and mobility concepts, the technologies TDMA, CDMA and OFDM, the generations from 1G to 4G, and the systems GSM, UMTS, 1X and LTE. This chapter is completed with WiFi and satellite.
PART III THE IP PACKET-SWITCHED TELECOM NETWORK (IP-PSTN)
11 "DATA" COMMUNICATIONS CONCEPTS
12 CODING, FRAMES AND PACKETS
13 THE OSI LAYERS AND PROTOCOL STACKS
14 ETHERNET, LANS AND VLANS
15 IP NETWORKS, ROUTERS AND ADDRESSES
16 MPLS AND CARRIER NETWORKS
17 THE INTERNET
18 WRAPPING UP
The third part of Telecom 101 is dedicated to the new-generation IP telecommunications network.
We begin by understanding how convergence was achieved by treating voice and video like data – then accordingly, cover the fundamentals of what used to be called “data communications”: DTEs, DCEs, LANs and WANs and the crucial concepts of packets and frames.
There are so many functions that need to be performed to implement phone calls, television, web browsing, email and everything else over the IP network, a structure is necessary to be able to identify and discuss separate issues separately. For this purpose, there is a chapter on the OSI Reference Model and its layers, identifying what the layers are, examples of protocols for each layer and how they work together in a protocol stack.
Then we begin moving up the layers. The next chapter is on Ethernet, LANs and VLANs (Layer 2), including MAC addresses and MAC frames, LAN cables, Optical Ethernet, LAN switches and how VLANs are used to separate traffic.
The next chapter is all about IP (Layer 3): how routers implement the network, routing tables, IP addresses, subnets, IPv4 address classes, static addresses, dynamic addresses and DHCP; public addresses, private addresses and NAT; and an overview of IP version 6.
On a real-world telecom network, a traffic management system is required. This is implemented with a technique called in general virtual circuits, and in particular with MPLS. The next chapter in the book covers the fundamentals, briefly reviews legacy technologies X.25, Frame Relay and ATM, then focuses on MPLS and how it is used to implement VPNs, Class of Service, service integration and traffic aggregation.
The last main chapter is on the Internet: its origins, what an ISP is and how an ISP connects to the rest of the Internet via transit and peering, the web, the Domain Name System, HTML and HTTP, SSL, MIME and base- 64 encoding for email, Internet telephony and Internet VPNs vs. business customer “MPLS service”.
The final chapter is a summary and wrap-up, covering technology deployment from the top down, useful reference charts listing all of the technologies, standard network designs and ending with a look at The Future.
Telecommunications technology is in constant change – and some technologies that used to be of prime importance are not so important today, and so have been moved from the main part of the book into appendices.
The very last part of the book provides a comprehensive list decoding mainstream acronyms and abbreviations used in telecom.

“It’s like a symphony meeting an encyclopedia meeting a spy novel.”
–Michael Ford, Corero Network Security
On the Internet, every action leaves a mark–in routers, firewalls, web proxies, and within network traffic itself. When a hacker breaks into a bank, or an insider smuggles secrets to a competitor, evidence of the crime is always left behind.
Learn to recognize hackers’ tracks and uncover network-based evidence in Network Forensics: Tracking Hackers through Cyberspace. Carve suspicious email attachments from packet captures. Use flow records to track an intruder as he pivots through the network. Analyze a real-world wireless encryption-cracking attack (and then crack the key yourself). Reconstruct a suspect’s web surfing history–and cached web pages, too–from a web proxy. Uncover DNS-tunneled traffic. Dissect the Operation Aurora exploit, caught on the wire.
Throughout the text, step-by-step case studies guide you through the analysis of network-based evidence. You can download the evidence files from the authors’ web site (lmgsecurity.com), and follow along to gain hands-on experience.
Hackers leave footprints all across the Internet. Can you find their tracks and solve the case? Pick up Network Forensics and find out.
