Securing the Borderless Network reveals New techniques for securing advanced Web 2.0, virtualization, mobility, and collaborative applications

Today’s new Web 2.0, virtualization, mobility, telepresence, and collaborative applications offer immense potential for enhancing productivity and competitive advantage. However, they also introduce daunting new security issues, many of which are already being exploited by cybercriminals. Securing the Borderless Network is the first book entirely focused on helping senior IT decision-makers understand, manage, and mitigate the security risks of these new collaborative technologies.

Cisco® security technology expert Tom Gillis brings together systematic, timely decision-making and technical guidance for companies of all sizes: information and techniques for protecting collaborative systems without compromising their business benefits. You’ll walk through multiple scenarios and case studies, from Cisco Webex® conferencing to social networking to cloud computing. For each scenario, the author identifies key security risks and presents proven best-practice responses, both technical and nontechnical.

Securing the Borderless Network reviews the latest Cisco technology solutions for managing identity and securing networks, content, endpoints, and applications. The book concludes by discussing the evolution toward "Web 3.0" applications and the Cisco security vision for the borderless enterprise, providing you with a complete security overview for this quickly evolving network paradigm.

    An executive review of modern security

    "Securing the Borderless Network" is a good executive level summary of the issues that any IT manager needs to understand. At only 148 pages it can be read fairly quickly and the author has a writing style that made the subject engaging. I have read books that made their subjects more boring than was needed and luckily the author does a fine job of making security sound interesting and critical for an organization.

    The topics range from cloud computing, smart phones, malware, identity management, data backup and loss, and real world security policies. Each topic does a good job showing enough history for understanding how a subject came to be relevant today. I had not seen a picture of an Apple Newton in a long time, but there it was in the history section of the smart phone chapter.

    It should be pointed out that this is by Cisco Press and they do modestly discuss their own products as ways to address pretty much all of the issues brought up in the book. The author made this reasonably unobtrusive and I was left with a better appreciation for Cisco products without feeling intruded upon during the presentation of any issues.

    Also, this is not a technical book. A programmer wanting to better secure their database programming will not necessarily need this book, but their manager and executive staff will be well served by it. While there are some graphs, the diagrams are usually screenshots, product pictures, and bullet points. Actual implementation is left as an exercise for the reader or, certainly, the subject of a much more technical book. Instead, get this book for decision makers who need to understand why the IT staff wants more emphasis on securing their network rather than simply providing services.

    Calming fears about data security

    If you have employees begging to be allowed to use their cool new smartphones to read company email and access corporate data - and you're nervous as heck about it - this book is for you. t seems to me that concerns about security are natural when sensitive information moves outside of the relative safety of corporate networks. Securing the Borderless Network tells you how to create an open, collaborative environment for your workers, no matter how far-flung they are, while at the same time explaining how this collaboration can coexist with security. The writing is clear and straightforward, and the advice is practical.

    Handy reference book on security threats in the Web 2.0 world

    The goal of this book is to educate the senior IT 'decision- makers' on the issues surrounding securing collaborative technologies. Starting with a review of network security in general, moving to what collaboration technologies are all about and the expectations around these technologies to the modern workforce, and then to what cloud computing means, Tom Gillis from Cisco covers a lot of territory in a brief period of time in a language that anyone can understand.

    Gillis continues the book by covering other threats that can't be ignored: smartphones, malware, and some of the technology that can be used to combat these threats. He then wraps up with the importance of Acceptable Use policies, the actualities of data loss, and most importantly delivers the message: hope exists that these threats can be mitigated.

    One word of caution: as Gillis is an employee of Cisco, there is a heavy emphasis on some of the tools that they offer in the collaboration area. Readers need to keep in mind that these are examples of part of the market- there are other options out there!

    In a small, lightweight paperback, 'Securing the Borderless Network' is a helpful explanation of the information security threats that face the modern network. It's useful for the non-technical individual interested in learning what the big fuss is all about.

    Solid intoduction to Web 2.0, Cloud Computing and Security challenges posed by them

    This book is an entertaining and fun read and any technology enthusiast should read it. I was able to read this book in two nights and enjoyed it like I was reading Dan Brown's Angels and Demons. The author Tom Gillis clearly explains new challenges faced by IT Security Managers due to Web 2.0, Cloud Computing and mobile workforce. The author clearly explains why Web 2.0 and Cloud Computing are Enterprise management's biggest fear and clearly expose IT's inflexibility. Web 2.0 gives rise to Work 2.0 and whether IT departments like it or not, this trend is here to stay. Today employees work anytime from anywhere using any device and need connectivity 24x7x365 which increases their productivity and job satisfaction. But this trend is major headache for C-Level enterprise executives and IT Security managers as they don't know how to secure this information flow when communication may not even touch their networks like Salesforce hosting your company's CRM and employee access this data using his iPhone. Traditional network boundaries are blurring and it is becoming very difficult to protect data whether it is in motion or rest. Tom also explains Next Generation Firewalls that will not do filtering based on port, protocol and IP but instead will be Content, Application and User Identity aware. How about writing a firewall policy saying "John Doe" from "Engineering" department can access "[...]" and cannot exceed "2 Mbps"instead of IP address x.x.x.x/32 can access y.y.y.y/32 on port 80. I think you got the point :-)

    The problem statement is clearly defined with many excellent examples and interview excerpts from real enterprises. Last few chapters are fully focused on highlighting solutions for Web 2.0 security challenges and I have to admit, Cisco vision is neat and they are focusing on both On-Prem and Cloud based security solutions. The author didn't go into implementation or design details but ideas like Flexible Identity Fabric and multilayer scanning engines are pretty encouraging. The concept of Policy Management consoles (where enforcement and Policy management functions are decoupled) along with Security Intelligence Operations (SIO) are good initiatives by Cisco.

    Overall I thoroughly enjoyed this book and in my opinion the content is very well organized, timely and fresh. Tom Gillis is very knowledgeable and he certainly delivered a book that will benefit many IT managers,executives and staff members.

    nice explanation of firewalls

    Cisco is making a big push into cloud computing and the much bruited Web 2.0. Gillis explains these trends in a concise way, and tries to minimise the technical jargon.

    The first chapter is distinguished by an excellent summary of how firewalls work. Gillis skips all the low level product details that you typically find in other discussions about firewalls. Instead, he describes that all firewalls are divided into 2 types - proxy and packet filters. And that the latter are now largely represented by stateful packet filters. The relative merits of these are given, along with the trends in the last 15 or so years. If you have another book devoted to firewalls, consider perhaps first reading this chapter of Gillis to orient yourself before plunging into the former.

    Gillis then goes on to talk about cloud computing. Note however that the two example companies he covers are small. They don't have and cannot afford much in the way of dedicated IT people or equipment. So perhaps for situations like theirs, a so-called cloud remote access, where their data is hosted on some third party data center, makes sense. More plausibly, cloud computing usage may indeed expand, but likely there will always be both cases; of companies using it and others going with their own data centers.

    The book also delves into the various manifestations of malware, like viruses, botnets, spam and phishing. If you want more details, try Malware: Fighting Malicious Code or The Rootkit Arsenal: Escape and Evasion in the Dark Corners of the System.
