McAfee Network Access Control

McAfee System Protection
Protect your network from noncompliant or infected systems
Noncompliant, infected, or misconfigured systems pose security risks and incur costs due to system downtime and restoration. Even one infected host already on the network can cause disruptions to network bandwidth or can infect other compliant systems. Boost NAC with McAfee IntruShield® IPS to protect high-risk areas on the network by identifying, quarantining, and remediating infected devices.

Yahoo Partners With McAfee To Make Search More Secure
Following Google (NSDQ: GOOG)'s lead, Yahoo (NSDQ: YHOO) is moving to make its search engine safer.
Yahoo and McAfee on Tuesday announced a partnership to integrate McAfee's SiteAdvisor technology with Yahoo Search. SiteAdvisor tracks Web site security issues, identifying sites associated with adware, malware, spyware, phishing, and spam.


More Security Insights White Papers CISSP Exam Tips Security vs. Flexibility: Must IT Management Choose? WebcastsWeb 2.0: Business Opportunity or Security Threat? Managing Risk and Bringing Rigor to Information Security ReportsWeb 2.0 Gets Down To Business Rolling Review: Microsoft NAP The new SearchScan feature in Yahoo Search is a manifestation of the partnership. It provides red warning messages about the risks posed by Web sites that appear in Yahoo Search results lists.
Google began flagging risky search results in February 2007.

"Searching on the Web can present a minefield of spyware, malware, and other malicious sites that can cause serious harm to your PC and cost you valuable time and money," said Vish Makhijani, senior VP and general manager of Yahoo Search, in a blog post. "We are taking steps to make you feel safe when searching the Web -- warning you about dangerous sites before you click on them."

According to Makhijani, "No other search engine today offers you this level of warning before visiting sites. Period."

Citing a March 2008 survey conducted by marketing research services provider Decipher, Yahoo and McAfee claim that 65% of Americans online are more worried about clicking unsecured search listings than the threat of neighborhood crime, getting one's wallet stolen, or e-mail scams. Unfortunately, Decipher hasn't posted this survey online, making it harder to divine why so many people supposedly prefer being pistol-whipped and robbed to a malware infection.

Tim Dowling, VP of McAfee's Web security group, said that SearchScan tests for browser exploits, so it will detect sites where malware is delivered through online ads.

According to a Google security report published in February, 2% of malicious Web sites were delivering malware via advertising. Because ads tend to be placed on popular sites, searchers encounter them more often than their general prevalence suggests. "On average, 12% of the overall search results that returned landing pages were associated with malicious content due to unsafe ads," the report said.

Flagging such sites, however, is not without problems. Web sites penalized by McAfee's scarlet letter may see a drop in visitors despite the possibility that the fault may lie with the security of the site's ad syndication network rather than with the hosting site itself. Still, fear of such stigma may make site owners demand better security at ad networks, which would improve Internet safety for everyone.

It's something of a surprise to find Yahoo striking a deal with McAfee given that McAfee in May 2007 fingered Yahoo as the search engine with the greatest percentage of risky search results (5.4%). But perhaps having partnered with McAfee, Yahoo will fare better in McAfee's forthcoming 2008 State of Search Engine Safety survey.

Asked whether Yahoo's new relationship with McAfee represents a conflict of interest that might affect the search engine's ranking in McAfee's upcoming survey, Dowling replied, "It's hard to say whether there's a real conflict of interest. It's a pretty quantitative study." He added that due to Yahoo's commitment to cleaner search results, "I would expect Yahoo to be the safest search engine, or one of them."

Dowling said McAfee was running a bit behind in compiling the data for its 2008 search safety survey but did provide a preview: Sponsored search results are twice as likely to link to malicious sites as organic search results, he said. "The bad guys try to look good and Internet advertising is a way they can buy their way into a higher search result position," he said.

Dowling also said that search engines collectively serve 8 billion risky sites per month worldwide.

I want to start out by saying that this book completely exceeded my expectations for the first NAC Appliance book. I wish this was published 3 years ago. The author clearly articulates the business benefits of NAC, including how NAC provides return on investment (ROI), which gives any reader the know-how to wisely purchase Cisco NAC Appliance. He also shows his technical expertise by diving extremely deep into the inner workings of Cisco NAC Appliance, which gives engineers, consultants, and operations the information they need to successfully deploy or maintain the product.

This book shows great details into the process flows of In-Band & Out-of-Band users, Clean Access Agent (CAA) users and network scanning users. The information on the different deployment options and how to use them in diverse environments is great to start your NAC Design. This book makes the confusing topics seem easy and manageable.

Some of the highlights that caught my eye and I thought everyone would like were:

- Chapter on Host Security Policy - An amazing deal of information on how to design/create a Host Security Policy as it relates to NAC Appliance is invaluable to deployments

- Exploration of High Availability and Load Balancing - Information on how to load balance Clean Access Servers using the CSM, CSS, ACE and PBR cannot be found anywhere else. This includes saving money on Failover Bundles by using N+1 Failover

- Layer 3 OOB Deployment options - Walk through of the benefits of the different methods of deploying L3 OOB, e.g. PBR, ACLS, VPNs, etc.

- Deployment Best Practices - An entire chapter on how to plan, schedule, and keep all parties happy for your NAC Appliance deployment

- Monitoring & Troubleshooting information - detailed list of all logs located on the CAM and CAS, as well as the information on how to troubleshoot and monitor online users

All in all this is a great book and I would recommend it for all people interested in Buying, Deploying, Operating, or Troubleshooting Cisco NAC Appliance. This is definitely a great reference manual to have at your desk!

The Cisco Self Securing Network platform is currently structured around several cornerstone technologies of which the Cisco Clean Access technology is a leading component. The Cisco Clean Access technology is one of several industry wide Network Admission Control (NAC) technologies which rely on a combination of client-server components. The Cisco Clean Access suite includes a client component which could be host-installed applet or a browser based applet that can read basic configuration data from a host machine and communicate compliance to enterprise defined rules/policies which are pre-defined on a clean access server appliance and other coorperating systems. The book, Cisco NAC Appliance is a good guide for administrators deploying this complex set of solutions brought from Perfigo Inc. after Perfigo's acquisition by Cisco 2006.

The book's organization and tone is aimed at security architects, security managers and security administrators. While a security architect will better understand the various deployment options and thus the place of the Cisco NAC framework in an enterprise, security managers will get a comprehensive enough view of the Cisco NAC framework to make the judgment call on actual deployment of the infrastructure and of course make decisions on cost/facility and better grapple with the potential cost benefit requests from enterprise's executive and the security administrator will have a quick guide handbook to help wade through the myriads of documentations from Cisco on its evolving SAFE architecture in general and the NAC framework in particular.

The organization of this book is excellent for the intended audience; six parts covering the basics of host security landscape, design of Cisco NAC appliance, developing a host security policy, the Cisco NAC configuration, some deployment best practices, and of course NAC appliance maintenance and troubleshooting. The six parts are laid out in fifteen accessible chapters spanning more than 500 pages with generous amount of configuration examples and screenshots.

With Cisco now having more than 45% market share in the endpoint access control market, books like these can only increase in importance as a guide to organizations grappling with the decision on what and where to deploy these technologies.

And for this volume, the taste of the pudding remains in the eating. So if you don't have a copy yet, go grab one (so long as you are interested in some endpoint security solutions now or at some point in the future). As for rating, I'll give it my best rating so far, four star out of five.
