AVIEN Malware Defense Guide for the Enterprise ReviewIf your book budget only allows for one book this year, this is the book you should buy. If you're a malware administrator for a small to large size enterprise this is the book that will help guide you through your day to day activities.
The section on detection a piece of malware that may be running on a user's machine is extremely helpful, the tools mentioned in that chapter will all become staple items in your outbreak "jumpkit" after reading that section.
There really isn't any other book like this out on the market today. The entire book was written by global top professionals in the field that live with the malware threat on a daily basis. They are not people that are locked away in a lab somewhere only dissecting threats sent to them, although that is a part of many of their jobs. These authors know what it's like to be in the trenches, trying to protect their enterprise environments while still maintaining that extremely delicate balance that allows their users to perform the daily activities that they require to make the enterprise run smoothly. These authors help walk you through their sections as if they are right there with you guiding you along and answering your questions.AVIEN Malware Defense Guide for the Enterprise OverviewMembers of AVIEN (the Anti-Virus Information Exchange Network) have been setting agendas in malware management for several years: they led the way on generic filtering at the gateway, and in the sharing of information about new threats at a speed that even anti-virus companies were hard-pressed to match. AVIEN members represent the best-protected large organizations in the world, and millions of users. When they talk, security vendors listen: so should you. AVIEN's sister organization AVIEWS is an invaluable meeting ground between the security vendors and researchers who know most about malicious code and anti-malware technology, and the top security administrators of AVIEN who use those technologies in real life. This new book uniquely combines the knowledge of these two groups of experts. Anyone who is responsible for the security of business information systems should be aware of this major addition to security literature.* "Customer Power" takes up the theme of the sometimes stormy relationship between the antivirus industry and its customers, and tries to dispel some common myths. It then considers the roles of the independent researcher, the vendor-employed specialist, and the corporate security specialist.* "Stalkers on Your Desktop" considers the thorny issue of malware nomenclature and then takes a brief historical look at how we got here, before expanding on some of the malware-related problems we face today.* "A Tangled Web" discusses threats and countermeasures in the context of the World Wide Web. * "Big Bad Bots" tackles bots and botnets, arguably Public Cyber-Enemy Number One.* "Crème de la CyberCrime" takes readers into the underworld of old-school virus writing, criminal business models, and predicting future malware hotspots.* "Defense in Depth" takes a broad look at DiD in the enterprise, and looks at some specific tools and technologies.* "Perilous Outsorcery" offers sound advice on how to avoid the perils and pitfalls of outsourcing, incorporating a few horrible examples of how not to do it.* "Education in Education" offers some insights into user education from an educationalist's perspective, and looks at various aspects of security in schools and other educational establishments.* "DIY Malware Analysis" is a hands-on, hands-dirty approach to security management, considering malware analysis and forensics techniques and tools.* "Antivirus Evaluation & Testing" continues the D-I-Y theme, discussing at length some of the thorny issues around the evaluation and testing of antimalware software.* "AVIEN & AVIEWS: the Future" looks at future developments in AVIEN and AVIEWS..

Chained Exploits: Advanced Hacking Attacks from Start to Finish ReviewI looked forward to Chained Exploits (CE) by Whitaker, Evans and Voth with much anticipation as the concept is a much needed addition to the lexicon on information security. Often academic fields are severely limited by the vocabulary available to discuss issues and the "chained exploit" is sure to become a mainstay in the discourse of information security. Despite my enthusiasm for the concept, however, I was disappointed by the material presented in CE. The genius of the chained exploit is that it upends the traditional threat matrix, typically presented as:
[value of resource] x [likelihood of exploit] = [risk level]
For example, a high value resource that is unlikely to be exploited should be ranked as a low risk, as should a low value resource that is likely to be exploited. Think of this in terms of a temporary database of publically available information used to populate a user demonstration website that is wiped out every 24 hours. If that information is compromised it has no value, so even if the compromise is likely it is a low risk system. Conversely if a system that contains critical financial information is confined to a single workstation that is removed from any networking and housed in a guarded facility it too is a low risk system (since the likelihood of compromise is low).
Unfortunately many auditors make risk assessments based on circumstances in a vacuum. This is where the concept of "chained exploits" becomes so valuable. For instance, if a vulnerability were discovered in a local binary accessible to users that allows privilege escalation, but the local binary exists on a system that has no users (other than administrators who already have root privileges) it is often considered a low risk. Many times patches for these sorts of vulnerabilities are not installed because the patch could introduce instability and would not be considered worthy of the expense given the low risk. Similarly a vulnerability could be discovered in a web service that when exploited could allow a remote attacker to gain an unprivileged local account that, say, only had access to read and write to the /tmp directory. This could also be considered a low risk since such limited access wouldn't present any threat to the system. However, if you "chained exploits" for the two vulnerabilities you suddenly have a condition where a remote attacker can gain a local account and elevate their privilege! This contravenes the low risk ranking of the individual vulnerabilities. When combined they suddenly become a very high risk to the system.
It was this sort of "chain" that I hoped CE would explore. Instead the material presented in the book consisted of context to several high risk vulnerabilities to explain why they might be used in tandem. For instance, the book would propose a scenario where a remote attacker installed a backdoor rootkit on a corporate network workstation then used that workstation to access the central database using default system administrator credentials. Each of the conditions used in these "chains" are extremely high risk already, and thus the book doesn't present any new material for seasoned information security professionals to consider.
For a novice this book is a great resource. It is full of the sorts of horror stories that professionals are all too familiar with, but could potentially be eye opening for a neophyte or someone unfamiliar with computer security. At the very least it is a page turning exploration of very real and often under appreciated risks to enterprises.
I was disappointed that the book didn't raise the level of discourse in the information security field but I suspect that wasn't the point of Chained Exploits. Instead it reads like a greatest hits sequence prepared by veteran penetration testers. It makes for interesting reading, but it isn't particularly informative. Don't look for any new 0 day exploits (or even a discussion of how to find such flaws). Instead the book contains a litany of well known routes to system compromise and illustrative narratives that tie them together in real world scenarios.Chained Exploits: Advanced Hacking Attacks from Start to Finish OverviewThe complete guide to today's hard-to-defend chained attacks: performing them and preventing themNowadays, it's rare for malicious hackers to rely on just one exploit or tool; instead, they use "chained" exploits that integrate multiple forms of attack to achieve their goals. Chained exploits are far more complex and far more difficult to defend. Few security or hacking books cover them well and most don't cover them at all. Now there's a book that brings together start-to-finish information about today's most widespread chained exploits–both how to perform them and how to prevent them. Chained Exploits demonstrates this advanced hacking attack technique through detailed examples that reflect real-world attack strategies, use today's most common attack tools, and focus on actual high-value targets, including credit card and healthcare data. Relentlessly thorough and realistic, this book covers the full spectrum of attack avenues, from wireless networks to physical access and social engineering. Writing for security, network, and other IT professionals, the authors take you through each attack, one step at a time, and then introduce today's most effective countermeasures— both technical and human. Coverage includes:Constructing convincing new phishing attacksDiscovering which sites other Web users are visitingWreaking havoc on IT security via wireless networksDisrupting competitors' Web sitesPerforming–and preventing–corporate espionageDestroying secure filesGaining access to private healthcare recordsAttacking the viewers of social networking pagesCreating entirely new exploitsand moreAndrew Whitaker, Director of Enterprise InfoSec and Networking for Training Camp, has been featured in The Wall Street Journal and BusinessWeek.
