Article: Analytics Brief: Securing The New Data Center

Analytics Brief: Securing The New Data Center
Virtualization changes the rules for how companies secure their data and their computing infrastructure.


In a recent InformationWeek poll, 70% of respondents report they’re running at least one virtualized server, yet less than 12% have a security strategy tailored to their virtual environment. Given the relative nascence of virtualization offerings for the x86 platform, this doesn’t come as a shock, but that also doesn’t mean it’s acceptable. Of those without a security plan in place, almost half believe that virtual machines are as secure as traditional servers, while another 18% admit they don’t know whether virtualization changes the rules of the game for security (see chart below of responses filtered for “no plan in place”).

There’s little doubt that virtualization is an important and disruptive technology that will, in a relatively short period, change the face of the data center. Because virtualization is so disruptive, it also will clearly change the rules for how enterprises secure their data and their computing infrastructure. And, while we don’t believe that virtualization should remain off limits until a security strategy is fully nailed down, smart organizations will develop security and management strategies as they develop deployment plans for virtualization.

chart: Confidence Level -- In your opinion, how do virtual servers compare with conventional server environments for information protection and security?
New threats to security come on two fronts. The first and most obvious is the additional software footprint represented by virtualization. On the desktop, virtualization is often implemented as an “application” that runs as a process under a desktop operating system, like Windows. For servers, hypervisors have emerged as the preferred method for introducing a hardware virtualization layer between the “bare metal” hardware and general-purpose operating systems.As such, hypervisors represent a relatively slim attack vector as they’re often implemented in less than 100,000 lines of code. When compared with the millions of lines that make up a general-purpose operating system, creating a bulletproof hypervisor is a more realistic goal, but flaws will still exist, and exploits will be created. All the major players report that building a secure hypervisor is a top priority. VMware’s CTO, Mendel Rosenblum, goes so far as to boast that no security holes will show up in VMware’s ESX product because of design flaws–of course, that leaves open the possibility of implementation errors. Unfortunately, the enterprise is left with little other than vendor assurances to work with. While tools exist to detect rootkits and other compromises on conventional operating systems, no tools exist to detect their presence in the hypervisor.

chart: Confidence Level -- In your opinion, how do virtual servers compare with conventional server environments for information protection and security?

ETTING SECURE
Help will probably come in two forms. First, it’s likely that as virtualization becomes more mainstream, hardware vendors will design end-user systems from the ground up to provide administrator-controlled VM partitions and hypervisor layers, making it harder for malware to enter systems.

A better fix uses the Trusted Platform Module found in most new x86 based systems. Using the TPM, software authenticity can be tested and inter-VM traffic can more easily be encrypted. Using the TPM’s ability to sign software makes it easier to determine that a system image has been altered and that it should be assumed to be compromised. Since the TPM is designed to be a tamper-proof hardware approach to encryption and software signing, it should help substantially in validating that software of all stripes hasn’t been corrupted by malware or by other means.The other substantive threat is a byproduct of how multiple virtual machines communicate with each other on the same system; that, along with the ability to move running VMs from machine to machine, renders most network-based security products much less effective.

chart: Security Strategy -- Does your organization have a formal security/information protection strategy for virtualization server environments?
One of the first production uses for x86 virtualization has been server consolidation. The idea is that a single powerful server running a number of VMs can replace potentially dozens of older, lightly loaded individual servers. With so many VMs running on a system, the amount of communication between them can be significant. For intraserver communication between VMs, all virtualization products create a virtual switch, which is then shared by all VMs on the server. External network security tools from firewalls to intrusion detection and prevention systems to anomalous behavior detectors are all, by definition, blind to network traffic that never leaves the physical server.One approach to securing multiple VMs on a single server is to ensure that all the VMs are running similar operating systems and that each has been properly patched. The notion is that if all systems running on a given server are similarly secure, their communications will be, too. Security products like host-based firewalls should be in place to provide what security they can.

A better solution is to use tools that are specifically intended to improve the security of virtualized environments.

Virtual appliances are, as the name suggests, VMs with a minimized and hardened operating system that’s been configured to precisely meet the needs of the appliance’s one application. The idea is to minimize or eliminate any operating system configuration work on the part of the end user, permitting rapid and consistent deployment with relatively little expertise required from the installer. Applications for virtual appliances range from grid computing to SaaS to security.

chart: VM Volume -- What fraction of your servers are virtualized?
Though a virtual appliance can be created for any virtualization environment, VMware is ahead of the field and has created a marketplace along with a try-before-you-buy Web site. More than 100 security-related virtual appliances are listed on the site. Only a fraction of those are from commercial vendors. The rest are applications created by internal groups or open source collaborations.Among the vendors listed are Astaro, with a unified threat management appliance; Blue Lane, with a virtual patching appliance; Catbird, with a security agent; and Reflex, with an intrusion prevention appliance. As this group indicates, virtual appliances, much as their physical-world kin do for the legacy data center, can fill many of the security gaps created by a virtualized environment.

While the tools to create a secure virtualized environment are now showing up, it would be a mistake to think that virtualization security is just about buying a different set of security tools. Greg Shipley, CTO of security research company Neohapsis, offers this advice: “Take a hard look at what threats you actually think you’re facing, and what tools or techniques (which might not involve a technology purchase!) are out there to help mitigate them.” Shipley maintains a healthy skepticism of security software vendors. He “can’t help but wonder if some of the vendors out there are simply looking at all the virtualization going on and saying, ‘Hey, how do I sell security to all these VMware shops?’ I think part of the burden on us users/consumers of the technology is to discuss what the true threat vectors are and then look to at tools.” Virtualization will change the face of computing from the desktop to the data center. Getting security right requires reassessing the approach to and goals for security. Platform and network security, which have been the mainstay of most security efforts to date, will give way to securing data and restricting its use to only those who are, by policy, allowed to use it.

Intellectual Property- what is it and how do we secure it?

December 29th, 2007

Intellectual Property

Intellectual property, a major component of Intellectual Capital, is described in Chapter 4 of IT Governance: Guidelines for Directors. Intellectual property (IP) is a term used to describe certain legal entitlements which are concerned with the protection and usage of recorded media (TV programmes/films/music), written works, names and inventions. IP is usually in the form of:

  • a patent,
  • a copyright,
  • a trademark or
  • a design

Every country has its own form of copyright legislation. In the UK, the UK Patent Office provides substantial information about UK intellectual property rights (’IPR’), the Copyright Licensing Agency is a critical resource, and the World Intellectual Property Organization (’WIPO’) “promotes intellectual property throughout the world.” The Handbook of Intellectual Property Management is an excellent reference book on the subject.

Further insights into the many different types of IP and the laws governing them are detailed in the Handbook of European Intellectual Property Management which predominantly covers the world of IP from a European perspective or, if you are looking for a specifically legal manual, then Intellectual Property Law, Fourth Edition provides a worldwide perspective and introduction to the subjects.

Both the books mentioned above are available for immediate despatch from the IT Governance online store. IT Governance have searched the book publishing world exhaustively for the most interesting and highly authoritative books on the many different aspects of IP; these are now readily available in one place for you to purchase. Please read on for more information on IP and the books associated with specific aspects of IP.

Copyright

Copyright is primarily concerned with the right to use a certain piece of information or a particular expression. Its main principle is that it allows the copyright holder to regulate the use of the item protected by copyright.

The most visible sign that an item is protected by copyright is the symbol © which is usually clearly featured on the item in question. However, this symbol has never been legally recognised.

Copyright can be described in simple terms as the ‘the right to copy the item in question’. If you are looking to understand the ins and outs of copyright, then the best book for you to read is A User’s Guide to Copyright, Sixth Edition. This cuts through the jargon to provide both legal and non-legal professionals with a guide to the world of copyright.

The law governing copyright is standardised across the world by treaties such as the Berne Convention. If you are looking to grasp the fundamentals of these copyright treaties and gain interpretive guidance, then the doubly authoritative manual, International Copyright and Neighbouring Rights: The Berne Convention and Beyond, Second Edition, is highly recommended. This is a two book set from Oxford University Press (OUP) which offers highly intelligent insights and guidance into the complex issue of copyright law. Additionally, copies of the most of the major copyright agreements and treaties, such as the Berne and Rome Conventions, are included.

Patents

Patents are generally a set of rights granted to an inventor, or to a person or organisation associated with the inventor, for a fixed period of time. These rights are granted in exchange for disclosure of an invention or idea.

Patents usually grant a period of exclusivity in which the inventor, or associated individuals/organisations, can prevent others from making, using, selling, offering to sell or importing the invention. However, these rights are not the same in all countries.

If you are looking to ascertain the ins and outs of UK and EU patent law then A User’s Guide to Patents, Second Edition provides a thorough understanding of these articles. It also addresses many of the wider public policy issues of patents.

There are many different international agreements and treaties governing how patents are enforced. However, these agreements or treaties are usually enshrined in local laws. The main agreements and treaties governing the use of patents are the Trade Related Aspects of Intellectual Property (TRIPS) Agreement and the Paris Convention for the Protection of Industrial Property. Further information on the TRIPS Agreement in particular can be found in a book called Trade Related Aspects of Intellectual Property Rights: A Commentary on the TRIPS Agreement. This book distils the essence of the TRIPS Agreement making it easily interpretable by the layman as well as the legal professional.

For a more thorough country-by-country approach to the legal aspects of patents and which treaties or agreements are, in effect, within a particular country then International Patent Treaties with Commentary is essential reading. It provides country-by-country information of the particular patent laws operating in that country, as well as providing information on how to maximise your patent rights in that country.

Patent searching can often be a difficult task: you can pay third party organisations to undertake searches for you, or you can do it yourself on websites such as Google Patent Search, the UK Patent Office or the United States Patent and Trademark Office’s website.

If you are looking for tried and tested methods of searching for patents, and don’t want to pay a third party service provider to do searches for you, then the methods conveyed in Patent Searching: Tool & Techniques are essential. Make sure before filing your patent, that one does not exist for an invention similar to your own, and save time and money on third party services by using the methods in this book.

Trademarks

A trademark is a unique and distinctive sign, or indicator of some type, which is used to distinguish a company’s, person’s or legal entity’s products or services from other entities products or services.

Trademarks are usually names, logos, designs, symbols or words. They can also be a combination of all of the previous elements put together.

Trademark rights confer exclusive rights of usage of the trademark within a certain market to licensors. More than one organisation can have rights to use a certain trademark, however the market they can use it in is limited. An example of this would be Apple Music and Apple Computers; the trademark here being an apple symbol.

Further information on the correct usage of trademarks can be found in a highly authoritative manual called Trade Mark Use, which is published by Oxford University Press. This manual clearly describes the correct usage of trademarks and the laws that cover the many different aspects of trademarking.

If you are looking to correctly classify your trademarks in accordance with the Nice Treaty, which is one of the main treaties governing the world trademark system, then International Trademark Classification: A Guide to the Nice Agreement is the essential manual you need. The advice included in this handy desk reference is fully in line with the ninth edition of the Nice Classification.

The above manual is written by a high authoritative author, Jesse N. Roberts who is the administrator of trademark classification at the United States Patent and Trademark Office.

Licensing Intellectual Property

Many organisations choose to license their trademarks, patents and copyrights to third parties for economic and other purposes. However, if you don’t understand the fundamentals of doing so, you can soon find yourself bogged down in a legal mire.

Essentials of Licensing Intellectual Property distils the key information you need to know if your organisation is considering licensing its IP to third party organisations. It demystifies the entire process of IP licensing by providing best-practice processes for every key stage of IP licensing.

Intellectual Property Law

There are many different agreements and treaties governing the many different types of intellectual property. IT Governance have scoured the world of publishing to assemble the best selection of both practical and authoritative books on the subject. Whether you are looking for a book covering the TRIPS Agreement or the Nice Treaty, then you will find it here:

Creating, Managing and Measuring Intellectual Property

For those who want to go about creating a portfolio of IP, knowing where to start can be very confusing and frustrating. Knowing how to protect IP, which treaties and agreements apply, and understanding the IP management process from creation to fruition are key requirements.

The Handbook of Intellectual Property provides a one-stop resource covering the main aspects of IP. Whichever aspect you are looking for, the information in this book is bound to be of interest to you.

It is often not appreciated how much value the effective management of IP can bring to an organisation. However, this is understandable, as IP is, in itself, intangible. In Tangible Strategies for Intangible Assets, the author provides methods for measuring, realising and managing an organisation’s intellectual property. The methods covered include the Balanced Scorecard approach amongst many others. Sample case studies are given of how the methods in the book have been used successfully, including eBay and Amazon amongst many others.

TAKING RISK ON BOARD. How global business leaders view risk

December 29th, 2007

This briefing paper draws a number of onclusions, based on a programme of in-depth interviews with business leaders
and industry analysts, and combined with extensive desk research, all carried out by the Economist Intelligence Unit.

“That business risks are proliferating in an
increasingly competitive world is beyond
dispute. Risks to business continuity and
to intangible assets such as intellectual
property and reputation are rising as the
economy becomes ever more global.
At the same time, the post-Enron era has
brought heightened focus on the role and
responsibility of corporate boards and their
members. So, just how high is risk
management on the corporate agenda?

Ask the Auditor: Who is Responsible for Information Security?

December 29th, 2007

Our new column, “Ask the Auditor,” answers real questions submitted by real readers. This week, certified internal auditor and certified information systems auditor Dan Swanson answers the question of who is responsible for information security.

By Dan Swanson

A Reader Asks: Who is responsible for information security?

The Auditor Responds: In short, the board of directors, management (of both staff and business lines), and internal audit functions all have significant roles in auditing information security. The big question for many companies is how these stakeholders should work together to ensure that everything that should be done to protect sensitive data is being done—and that the company’s key assets are protected appropriately.

1) Staff and line-of-business managers must have a voice in the design and implementation information security programs, since these managers are ultimately responsible for protecting and enhancing the value of the organization’s assets, including information assets. Managers must also review and monitor security controls to ensure they are appropriate, despite ever-changing risks and business requirements. This is, in fact, a form of auditing information security. And, finally, managers who own business-unit information should also help define their security requirements, based on business objectives, the significance of the information involved, legal requirements, and the seriousness of threats to data privacy.

Under a separate category of management, information security managers should organize and implement the organization’s information security program, including its monitoring (testing) program.

Although business managers often try to assign information security responsibilities to an information security management function, all parts of the organization have information security responsibilities. Security goals include a mixture of technical, procedural, and oversight controls, all of which should be reviewed or tested to ensure they are (a) adequate, as defined to mitigate information security risks, and (b) reasonably effective in practice.

Finally, executive management must provide leadership to ensure that information security efforts are supported and understood across the organization. Executive management must also dedicate sufficient resources to allow controls to be effective.

2) The board of directors must provide oversight at a level above other business managers. The director’s role in information security is to ask managers the right questions and encourage the right results. Directors must set the right tone at the top, communicating to executive management the business imperative of effective information security management.

3) The internal audit function provides strategic, operational, and tactical value to an organization’s operations. For example, internal auditing:

  • Tells the board and management whether business units understand the importance of security and adhere to policies; whether key information assets and systems are secure; and whether programs are in place for continually updating and strengthening safeguards against internal and external security threats
  • Provides assurance to both directors and managers that information security is as good as people say it is. Auditors identify weaknesses in existing security efforts, along with corresponding opportunities for improvement.
  • Helps the board and management understand whether the information security function has the resources, systems, and processes it needs to be efficient and effective
  • Independently validate that the organization’s information security program efforts are proactive and effective against current and emerging threats. To provide this level of assurance, internal auditors also compare current organizational practices with industry practices to discern whether their organization is operating comparable to others.

Ensuring that information security systems and management are subject to audit and review by qualified professional reviews and audits, corporate leaders advance the goal of overseeing the organization’s information security program and ensuring its continuous improvement and success.

To fulfill its potential, the internal audit function needs to:

  • Know what they are doing (i.e., have the skills to perform appropriate security audits)
  • Have a long term information security audit plan
  • Have a strong understanding of the technical and business environments
  • Know what to ask for

Information security auditing should be planned with an eye to ever-changing technical and business environments. The auditing function should “complement,” but never replace, management’s responsibility to ensure their IT controls are operating properly.

Resources

Proactively studying “what’s new” is a fundamental requirement for implementing and auditing information security effectively. Landmark guidance is issued every few years. These “classics” offer important knowledge relevant to all security stakeholders. The following list represents several classics, as well as some very new information, from a variety of leading resources relating to information security and its control and auditing.

Passenger Says He Hacked Windows In New York Taxi Display Screen

December 28th, 2007

A software engineer says he accessed a New York City cab’s video display system files after seeing an error message on the screen.

 



A New York City software engineer managed to gain access to the operating system for a touch-screen display available in the back seat of many Manhattan taxicabs and also used it to connect to the Internet. But no sensitive information or critical systems were compromised, according to the display systems vendor. The display is used to present short videos and ads to taxi riders, and can be used to pay the taxi fare with a credit card. A VeriFone Transportation Systems spokesman told InformationWeek Thursday that passengers’ credit card data is encrypted and isn’t stored locally, so it wasn’t compromised. He also said the cab had an outdated modem, used while the city tested the display systems.

Billy Chasen posted photos on his blog earlier this month showing that he accessed a New York City cab’s video display system files after seeing an error message on the screen. The artist and software engineer explained in the blog that he managed to open Internet Explorer, launched the Connection Wizard, selected aSprint (NYSE: S) card for a dial-up connection, and accessed Adobe (NSDQ: ADBE)’s Web site.

Chasen said he opened files and “had full administrative access to everything on the PC.”

“It was not only a security flaw, but people also pay with the screen if they use a credit card,” he said, adding the information could be stored locally.

“What I did was a much bigger problem than GPS tracking,” he said. “You’re essentially giving strangers access to a computer that is shared with hundreds of customers.”

Chasen went on to say that he could have installed software from the Internet.

The VeriFone spokesman, however, said Chasen had merely accessed media files, and passengers could not gain control of sensitive information.

“It’s a Windows-based system, so I could never say never,” he said. “But there is no credit card information stored in the system.”

The spokesman said the meter is integrated into the display system but not reliant upon it, so errors and unauthorized access would not affect meter functioning. He also pointed out that the New York City Taxi and Limousine Commission strictly regulates fares and meters.

“If the meters weren’t functioning right, the TLC would be all over it,” he said.

He also responded on Chasen’s blog, saying VeriFone investigated the incident, the old modem was replaced, and users cannot access editing tools on the system.

The new taxi technology systems, which are required for all New York cabs, generated controversy earlier this year and prompted some cab drivers to protest because they feared they would be monitored and tracked by GPS technology.

New Research Outlines Key Steps to Protect Sensitive Data - December 5, 2007

December 28th, 2007

Research from the IT Policy Compliance Group illustrates what works to protect sensitive data

CUPERTINO, Calif. - Dec. 5, 2007 - The IT Policy Compliance Group today announced the availability of its latest benchmark research report titled “Core Competencies for Protecting Sensitive Data” (PDF 1.5MB). The report, which incorporates responses from more than 450 organizations globally, concludes that only one in ten organizations is in the enviable position of adequately protecting their sensitive data. The report also analyzes the variables between those companies that are leaders and laggards in the area of data protection, providing insight into which actions and best practices can lead to less data loss, improved compliance results and sustained competitive advantage.
