Security Power Tools

May 26th, 2010  Tagged

Security Power Tools A solid resource for those interested in learning available tools - Gift Card Recipient - Oxnard, CA United States
I am very pleased with this purchase. The explanations and how-to directions are helping me get up to speed on a variety of powerful tools to assess security of a given environment. I recommend this book to others interested in finding out how secure their networked environments really are.
Invaluable security resource - Ben Rothke - USA
A classic ad for Snap-on brand tools featured the tagline, “I own the best, please don’t ask to borrow them.” In the new, complex world of IT security, picking the best tool for the job is no easy task. An indispensable reference on the subject, Security Power Tools, brings together a slew of expert authors who detail the best security tools available.

The main portion of the book is divided into six sections comprising 23 chapters that cover the following aspects of network security: reconnaissance, penetration, control, defense, monitoring, and discovery. The chapters cover tools for major operating systems from Unix/Linux, to Windows and Macintosh. The book is organized and progresses in a logical sequence that parallels real-world security scenarios and application of the tools.

Each section and subsection covers the subjects at hand, and then lists the appropriate tool for the job. The book not only lists and evaluates top tools but also explains how to access all of them, many for free, by downloading them from the Internet.

Many of the hacking countermeasures listed in the book may, however, require specific legal permission before use. Perhaps for this reason, the book opens with a chapter on legal and ethical issues. Yet the chapter does not read like a legal disclaimer–quite the contrary–it’s both engaging and fascinating.

This book is written for experienced security professionals who need an authoritative resource for finding the best IT security tool for the job. At nearly 800 pages, the text covers nearly every available security tool known, making it the de facto reference to such tool selection. Readers will find it an invaluable guide

:

What if you could sit down with some of the most talented security engineers in the world and ask any network security question you wanted? Security Power Tools lets you do exactly that! Members of Juniper Networks’ Security Engineering team and a few guest experts reveal how to use, tweak, and push the most popular network security applications, utilities, and tools available using Windows, Linux, Mac OS X, and Unix platforms.

Designed to be browsed, Security Power Tools offers you multiple approaches to network security via 23 cross-referenced chapters that review the best security tools on the planet for both black hat techniques and white hat defense tactics. It’s a must-have reference for network administrators, engineers and consultants with tips, tricks, and how-to advice for an assortment of freeware and commercial tools, ranging from intermediate level command-line operations to advanced programming of self-hiding exploits.

Security Power Tools details best practices for:

  • Reconnaissance — including tools for network scanning such as nmap; vulnerability scanning tools for Windows and Linux; LAN reconnaissance; tools to help with wireless reconnaissance; and custom packet generation
  • Penetration — such as the Metasploit framework for automated penetration of remote computers; tools to find wireless networks; exploitation framework applications; and tricks and tools to manipulate shellcodes
  • Control — including the configuration of several tools for use as backdoors; and a review of known rootkits for Windows and Linux
  • Defense — including host-based firewalls; host hardening for Windows and Linux networks; communication security with ssh; email security and anti-malware; and device security testing
  • Monitoring — such as tools to capture, and analyze packets; network monitoring with Honeyd and snort; and host monitoring of production servers for file changes
  • Discovery — including The Forensic Toolkit, SysInternals and other popular forensic tools; application fuzzer and fuzzing techniques; and the art of binary reverse engineering using tools like Interactive Disassembler and Ollydbg

A practical and timely network security ethics chapter written by a Stanford University professor of law completes the suite of topics and makes this book a goldmine of security information. Save yourself a ton of headaches and be prepared for any network security dilemma with Security Power Tools.

The TCP/IP Guide: A Comprehensive, Illustrated Internet Protocols Reference

May 24th, 2010  Tagged , , , , , ,

The TCP/IP Guide: A Comprehensive, Illustrated Internet Protocols Reference Repetitive and Dull - David Wolinsky -
Many of these reviews paint a glowing picture of this book. I don’t agree. The book is a tedious to read, I have now read up through the section describing TCP (over 50% of the book). Now on to my frustrations:

Technically speaking this book reads as a monolithic, modified RFC, all protocol no depth. He does a good job of going over IPv6 in its specific sections, but he does it disservice when discussing changes to UDP/TCP relating to IPv6, notably that the pseudoheader has changed. I would think that the target audience for this book isn’t for OS writers or graduate students but IT folk looking for a desk reference. One would ask though, why would IT folk need a desk reference when all this material is easily available online. Personally, I was expecting a book that went into the details of why TCP/IP/IPv6 would do this feature or that. I was hoping for an updated version of TCP Illustrated, now I have to break the bank and buy those books. Oh well.

I had significant issues with the author’s writing style. It was very amateurish. At the beginning of every chapter, the author begins with “I describe”, “I explain”, “I …”. That is an absurd style of writing, that I found very distracting. Every now and then he drops these lines in the text. Then while reading the text, the author always uses present tense “I talk about that in chapter 5″, when we’re in chapter 10. A much more clear form would have been “as discussed in Chapter 5″. The authors goal was to make a book that could easily be referenced off the shelf and make each chapter independent, which makes the book somewhat flawed. If the author had actually reviewed this book to remove unnecessary clutter, I have no doubt that it would retain just as much information at a 10 to 20% reduction in wasted paper.

I will say this, I am not disappointed in buying the book, it was a great refresher, but it promises too much but lacks a proper delivery. If you’re going in for a networking job interview or starting to consider research topics in networking, this may be the book for you. If you’re looking to do something after reading the book, you will be sorely disappointed.
Fast, Perfect, Would buy from Again - Stewart Van Cleave -
My book came alot faster than I was supposed to receive it, came in better quality than was even advertised, and the entire process went by extremely smoothly. I am extremely satisfied with the way this order was processed and I would definately do business with them again. A++
INCENTIVE PUBLICATION:

The TCP/IP Guide is both an encyclopedic and comprehensible guide to the TCP/IP protocol suite that will appeal to newcomers and the seasoned professional. It details the core protocols that make TCP/IP internetworks function, and the most important classical TCP/IP applications. Its personal, easy-going writing style lets anyone understand the dozens of protocols and technologies that run the Internet, with full coverage of PPP, ARP, IP, IPv6, IP NAT, IPSec, Mobile IP, ICMP, RIP, BGP, TCP, UDP, DNS, DHCP, SNMP, FTP, SMTP, NNTP, HTTP, Telnet and much more. The author offers not only a detailed view of the TCP/IP protocol suite, but also describes networking fundamentals and the important OSI Reference Model.

What reviewers are saying about The TCP/IP Guide:

“Keeps things interesting and flowing well enough that working one’s way through… is actually entertaining instead of torture.” — Slashdot

“This book is the Real Deal… If you’ve read as many bad IT books as I have, you will appreciate the mastery of Kozierok’s achievement. His warmth and style don’t smack you in the face at first, but keep reading, and you’ll discover an IT brother.” — WatchGuard Wire

“The most comprehensive guide to TCP/IP protocols we have ever come across. It also is the most readable. This is a book that will be staying on our shelves, and we highly recommend it.” — NetworkWorld

“Now I can retire all my other TCP/IP books I have gathering dust on my bookshelves… This book however may become timeless, because it not only talks about, but shows everything.” — MacCompanion

“Smartly illustrated, the book is easily navigated for both brief overviews of the subject matter and more in-depth study of TCP/IP-related topics… A welcome change from the information congestion common on the Information Superhighway” — About This Particular Mac

The Practical Intrusion Detection Handbook

May 22nd, 2010  Tagged , , ,

The Practical Intrusion Detection Handbook School Books - Thurman L. Harter - Terps Rule
This is a book that is required for my masters degree. It appears to be well organized and written in easy to understand manner.
Great IDS book for experts and beginners - -
This book is comprehensive and very readable. The information is excellent. Mr. Proctor’s experience helps show how intrusion detection systems are used in real life through a lot of examples. My company implemented network-based IDS last year and this book really helped us understand host-based IDS. In fact it’s the only book I’ve read on IDS that pays any significant attention to host-based IDS.

On the down side there are a few typos and the product section is a dated because several of the products mentioned have been acquired by other companies but this didn’t take away from the really useful information.

I’ve read the other books on intrusion detection and if you’ve got Northcutt’s book and this one you’ll have all the information you need.
Hidden product advertisement - Matthias Hofherr - München
In general, Mr. Proctor`s book is well done. Unfortunately, the autor uses many definitions which are not primarily used among ID specialists. These definitions are straight from the handbooks of Cybersafe Centrax, an IDS developed by the author (e.g. Network Node Intrusion Detection; the unique definitions of realtime/batched modes…). Additionally, Mr. Proctors seems to believe that only commercial IDSs are worthy of the professionel ID analyst. He wrongly describes Snort, an OpenSource NIDS published under GPL, as shareware and mentiones it very briefly in 3 sentences. Currently, 80-90% of all detects published on lists like Incidents are detected by Snort sensors ! Since Centrax is a first rate HIDS and only a second rate NIDS, the autor seems to be a very strong supporter of HIDS. This shows clearly through the whole book. The book gives a good overview over todays ID techniques combined with excellent examples. If Mr. Proctor had desisted from placing more or less hidden product advertisement in his book he would have done all readers a big favor.
: Intrusion detection systems are increasingly recognized as a key weapon in the war against computer crime. In The Practical Intrusion Detection Handbook, one of the field’s leading experts shows exactly how to use them to detect, deter, and respond to security threats. This is the only intrusion detection book to present practical advice for the entire lifecycle: choosing products, planning, deployment, operations, and beyond. Full of checklists and real-world case studies, The Practical Intrusion Detection Handbook demonstrates exactly how to integrate intrusion detection into a total strategy for protecting your information and e-commerce assets. Paul E. Proctor introduces each approach to intrusion detection, including host-based, network-based, and hybrid solutions; then offers practical selection criteria; and reviews the key factors associated with successful deployment. You’ll watch today’s best intrusion detection systems in action, through response, surveillance, damage assessment, and data forensics. Finally, Proctor addresses the future of intrusion detection — from standards and interoperability to law and ethics. Rather than emphasize the characteristics of attacks on computers and networks, The Practical Intrusion Detection Handbook places its focus on the tools, resources, and policies that should be in place to help security administrators do their jobs. It deals with preventing attacks, detecting and stopping them when they occur, and assessing–after the fact–the damage they cause. Throughout, the importance of record keeping is emphasized, particularly that accurate and unmuddled log files are necessary to back up legal charges or support certain firing decisions, if necessary. The business environment beyond the security officer’s cubicle is also explored, including how to justify security expenditures to organizational decision makers.

This isn’t exactly an academic text, but it’s a step removed from the sorts of play-by-play descriptions of attacks and defenses you’ll find in Stephen Northcutt’s security books–reference is made to those books, as a matter of fact. This hardback volume explains the appearance of various kinds of attacks in broad terms, and shows how intrusion detection systems (IDS) can spot and record the clues (Windows NT security log entries are often used as examples). The text is conversational and liberally studded with bulleted definitions, boxed case studies, and references to Web sites and paper documents. While a working security administrator would probably want to back this book with one of Northcutt’s texts and other more detailed books, The Practical Intrusion Detection Handbook makes an excellent choice for a student of business management who wants to be more than minimally informed about the operation of corporate information systems, so as to make better decisions about those systems. –David Wall

Topics covered: Intrusion detection systems (IDS) for whole networks as well as for individual computers, with emphasis on how intrusion detection works and how to configure it for maximum effectiveness and minimum false alarms. Establishing policies and setting procedures, and ways to choose IDS products and justify their purchase to management.

Guide to TCP/IP

Guide to TCP/IP CD not included - Lana - Brooklyn, NY
I was disappointed to get this book without the CD-Rom that the book calls for. The description for the book does not indicate that CD-Rom is included (so I assumed it did not come with one). But the book calls for CD-Rom, thus it should be included, if it is in new condition. Explanations of abbreviations are in regular typing instead of bold or at least italic. I found myself re-reading paragraphs, as they were written in a confusing way.
Wrong Edition - Jesse J. Mathews - minneapolis
I ordered this particular book because they stated the book was third edition. I have received the first edition of the book that is outdated.This old book is worthless to me and was a complete waste of money. I am a full time college student and cannot afford to throw money away to bad representation and false advertisement.
this book is fine but amazon is sucks - S. rizvi - usa
i like this book
but amazon sucks,
i think amazon is not good and fair to me.
amazon would not let me sell my book back that is not fair to me!
: Learn the concepts, terminology, protocols and services that the Transmission Control Protocol/Internet Protocol (TCP/IP) suite uses to make the Internet work! This book clearly displays and demonstrates TCP/IP capabilities while encouraging readers to interact with the protocols as well as to read and learn about them. It provides both the knowledge and tools would-be network administrators and analysts need to understand what’s happening on their networks, and to appreciate that behavior from the perspectives of traffic analysis and characterization, error detection and troubleshooting, security analysis and remedial action, and more.

Windows Forensic Analysis Including DVD Toolkit

May 18th, 2010  Tagged , , , ,

Windows Forensic Analysis Including DVD Toolkit Another Superb Book in Dgital Forensics from Harlan Carvey - A. E Heald - Portland ME USA
Harlan continues to give us a fascinating look “under the hood” from a forensics perspective, this time stepping away from Incident Response and into the operating system that must be examined. His work continues to be readable, detailed, and includes a DVD with extensive tools, many written by him. A jewel in my forensics library, again!
Great Book - Lannes J. Hilboldt -
This book is well written and a great asset to anyone doing computer investigations and forensics.
: The only book available on the market that addresses and discusses in-depth forensic analysis of Windows systems. Windows Forensic Analysis DVD Toolkit takes the reader to a whole new, undiscovered level of forensic analysis for Windows systems, providing unique information and resources not available anywhere else. This book covers both live and post-mortem response collection and analysis methodologies, addressing material that is applicable to law enforcement, the federal government, students, and consultants. This book also brings this material to the doorstep of system administrators, who are often the front line troops when an incident occurs, but due to staffing and budgets do not have the necessary knowledge to effectively respond. The companion DVD for the book contains significant, unique materials (movies, spreadsheet, code, etc.) not available any place else, as they were created by the author.

What is MSN Messenger?

May 9th, 2010  Tagged

MSN Messenger informs you while you have up-to-the-minute email in the Hotmail inbox & enables you to get entry into the inbox with a click of a key. You have complete power over who can call you and see whether you are on the Internet or not. At any occasion, you can have a look at the catalog of all clients who have put you into their recorders, plus you can simply block them if you select to do so. You can too provoke somebody in your record to access the web or to have fun with games through NetMeeting. A plan will even inform you while somebody you are conversing with is printing thus you can keep away from mixing messages.

Protocol

The MSN Messenger utilizes (MSNP) Microsoft Notification Protocol over (and alternatively over the HTTP to manage proxies) TCP to hook up to the .NET Messenger System - a system presented on connection 1863 of “messenger.hotmail.com.” Its existing edition is the MSNP13, utilized by MSN Messenger edition 7.5 as well as other 3rd-party users. Protocol is not totally covert; Microsoft revealed version MSNP2 to designers in the year1999 in web Draft, but never free editions eight, nine, ten, eleven or twelve to public. The .NET Messenger System servers now just accept protocol editions from eight and on, thus regulations of new instructions from editions eight, nine, ten, eleven and twelve are just recognized with the help of sniffers similar to Wireshark. The MSNP13 will be protocol utilized in Live Messenger of operating system. This application is yet not well-matched with the Mac Operating System X’s browser as of yet.

Xbox Live Integration

As in MSN Messenger-7.0, user now gets the power of combination with Microsoft’s Xbox Live online Gaming system. Clients of the MSN Messenger can link Xbox Web sites & link their gamertag to the Microsoft’s .NET Passport system. This will enable MSN Messenger to account for the client’s Xbox Live associates list, and enable them to launch game provocations to players, in order that client does not need to be on the Xbox Live so as to assemble games. This characteristic goes with the Microsoft’s ongoing object to set integration in their systems. After 2nd December, the Xbox Live Integration had provisionally broken down. This was because of modification in hardware as well as protocol carried with release of an Xbox 360. The fault was almost immediately solved. Spring 2007 Updating for Xbox 360 permitted MSN clients plus 360 clients to chat at the same time, and even registers what game an Xbox Live client is enjoying to their MSN-Messenger associates. This task does not consist of video or else audio chat among Xbox live clients & MSN clients. This software is freely available on the MSN website and can be downloaded in no time if you have access to Internet.

Computer Networking: Internet Protocols in Action

May 6th, 2010  Tagged , , , ,

Computer Networking: Internet Protocols in Action Informative and Enjoyable; great inro to networking protocols - abc123 -
I’m about half way through the book. It comes with a packet analyzer and pre-captured packets on a CD (make sure the CD is included!). The book walks you through analyzing the packets with the program and explains what you are looking at along the way. I feel I learned a lot. Maybe since I’m a newbie I don’t know what should have been there if, in fact, the book is lacking. However, I would definitely recommend this to others looking for an intro book that guides you through the basics and then some.
OK introduction, needs proofreading - sybernut -
This book is an OK introduction to networking, but has enough typos and contextual ambiguities to warrant a new edition. It walks a tightrope between giving a general overview and avoiding distracting details, a task rendered difficult by use of a protocol analyzer software which by definition exposes the reader to protocol details… this is sometimes not a bad thing as it makes you think and reflect (as do the typos and other mistakes :-) both within and beyond the scope of what the writer is saying about a particular topic.

The choice of top-down exposition of the Internet Protocol Stack layers has its problems, as this results in ‘forward references’ to lower-level material not yet explained, esp. due again to the use of the protocol analyzer which tantalizes us with details of the current and lower-level layers. A bottom-up approach might have been better.

The price is too high for the content given.
: Hands-on networking experience, without the lab!
The best way to learn about network protocols is to see them in action. But that doesn’t mean that you need a lab full of networking equipment. This revolutionary text and its accompanying CD give readers realistic hands-on experience working with network protocols, without requiring all the routers, switches, hubs, and PCs of an actual network.
Computer Networking: Internet Protocols in Action provides packet traces of real network activity on CD. Readers open the trace files using Ethereal, an open source network protocol analyzer, and follow the text to perform the exercises, gaining a thorough understanding of the material by seeing it in action.
Features
* Practicality: Readers are able to learn by doing, without having to use actual networks. Instructors can add an active learning component to their course without the overhead of collecting the materials.
* Flexibility: This approach has been used successfully with students at the graduate and undergraduate levels. Appropriate for courses regardless of whether the instructor uses a bottom-up or a top-down approach.
* Completeness: The exercises take the reader from the basics of examining quiet and busy networks through application, transport, network, and link layers to the crucial issues of network security.
