Cisco extends NAC product lineup Cisco announced a pair of additions to its Network Admission Control (NAC) product line on Monday, launching new tools that promise to extend the authentication system to a greater variety of devices and office environments. 2007 InfoWorld CTO 25: Marc Willebeek-LeMair Dr. Marc Willebeek-LeMair, CTO of 3Com, is used to wrestling with weighty problems. After all, the man spent a decade at IBM's T. J. Watson Research Center working on so-called intelligent infrastructure technologies and has done research on everything from distributed computing and high-speed networking technologies to network processors and management systems. So when Willebeek-LeMair talks about the problems facing the enterprise networking industry, people tend to listen.  June 8, 3:00 a.m. PDT Cogneto: to identity and beyond! Multifactor authentication is all the rage these days, thanks to increasingly sophisticated trojans and phishing attacks and even rootkits aimed at stealing passwords and sensitive data. High-stakes online crime has even spurred financial services companies and some enterprises to consider new, "risk-based authentication" solutions, which examine behavioral patterns and session characteristics to identify rogue users. May 25, 3:00 a.m. PDT Future of NAC pits host against network Makers of network access control technologies find themselves dividing along familiar lines within the world of IT security as some providers evangelize a centralized, network-based approach for enforcing device authentication tools and others claim that NAC should reside on the endpoint. April 24, 7:15 a.m. PDT Sophos to integrate NAC into desktop security Sophos will weave network access control (NAC) functions into its client antivirus security product, Endpoint Security, over the next 12 months, the company's chief executive officer said on Thursday at CeBIT in Hanover, Germany. March 15, 9:34 a.m. PST Cisco backtracks on open source promise After promising to turn the client software for its CTA (Cisco Trust Agent) into an open-source application, Bob Gleichauf, CTO of Cisco's Security Technology Group, said that the company has not made up its mind yet about the future of the software. February 21, 3:00 a.m. PST Cisco going open source with NAC client As it develops the next generation of network security infrastructure, Cisco Systems Inc. is planning to cease development on its network admission control (NAC) client, the Cisco Trust Agent (CTA), and submit the source code for the software client to the open source community, Bob Gleichauf, CTO of Cisco's Security Technology Group, told InfoWorld. February 7, 3:06 p.m. PST Analysis: Cisco's transformation still a work in progress Cisco Systems used the RSA Security Conference in San Francisco to trumpet its transformation from "packet pusher" to "infrastructure" company, unveiling a string of product updates that unify its diverse security portfolio on Monday. February 6, 10:10 a.m. PST Accelerate your 802.1x rollout During the course of our NAC reviews, we also tested Cloudpath Networks' XpressConnect. XpressConnect is a small, browser-delivered agent that can reconfigure wireless access profiles and 802.1x supplicants. Placed on a captured portal page for guests or staff, it automatically configures systems for access to your 802.1x network, be it wired or wireless. As a result, 802.1x authentication is much easier to deploy than has been the case in the past. February 5, 3:00 a.m. PST NAC: How we tested Our test infrastructure for the NAC reviews included an edge switch for the client systems, a core switch with server VLANs for the common and secured servers, and a RADIUS server for authentication. Client systems connected into the edge switch, authenticated as defined for the specific scenarios, then accessed (or attempted to access) the various areas of the network: Internet, enterprise, and limited access. We created additional policy networks for remediation and scanning as well. February 5, 3:00 a.m. PST NAC smorgasbord: Four ways to police the network In this age of worms, zombies, and botnets, mobile computers themselves are a kind of Trojan horse. Do you know where that computer’s been? No, you really don’t. February 5, 3:00 a.m. PST NAC policy management wags the watchdog The most critical element of a NAC system is the policy management system. As every administrative interface that an administrator must use requires specialized focus and understanding, the ease with which an administrator can launch the policy management system, make the changes desired, view reports, and perform other management tasks is critical. No administrator is likely to have hours to devote to these systems each day, so the simplification and visualization provided by the system should be a primary consideration for shoppers (and a prime opportunity for differentiation among the vendors). February 5, 3:00 a.m. PST Eclipse, Novell near 'Big Bang' for identity Two open-source identity management projects said on Monday that they had achieved a key milestone in the development of open-source identity services that connect products regardless of maker or platform. January 29, 3:36 p.m. PST Cisco warns of vulnerabilities in NAC product Networking equipment vendor Cisco Systems Inc. issued an advisory to customers Wednesday about two serious vulnerabilities in its Cisco Clean Access software, a network access control product. January 4, 1:36 p.m. PST Networking: Convergence is at hand In networking, the big news of 2006 was the emergence of 10-Gigabit Ethernet as a mature, enterprise-ready technology. The past year also witnessed important advances in security and monitoring on the enterprise LAN, thanks to ever tightening integration and partnerships. January 1, 3:00 a.m. PST 2006 Year in Reviews: Networking After most of the vendors declined our invitation to a WAN shootout last year, we settled for a series of standalone reviews of WAN accelerators this year. As usual, Riverbed’s Steelhead shined -- so did products from Silver Peak, Blue Coat, and Cisco Systems, though they still swam in Steelhead’s wake. Perhaps competition will be stiff enough for a comparative test in 2007. Stay tuned. December 18, 3:00 a.m. PST Cisco opens R&D center in west of Ireland Cisco Systems Inc. will open a research center in Ireland to develop unified communications products. November 22, 8:21 a.m. PST Juniper releases Version 2 of NAC product With all the hype and anticipation that has surrounded the NAC (network access control) space in recent years, you can forgive IT administrators for assuming that full-featured NAC solutions were just around the corner. But progress on client screening and NAC has been agonizingly slow since the first NAC products hit the market in 2004. November 13, 3:00 a.m. PST Government agencies gear up for HSPD 12 Most major IT projects of any size are slow moving beasts: amorphous blobs of specs and builds and regression tests slouching toward completion, someday far in the future. October 23, 3:00 a.m. PDT Emerging security solutions vie for approval Aside from a flurry of beta releases, security updates, and the usual E.U. he said/she said dance, it's been a pretty quiet week in Redmond. In case you're wondering which betas to watch for (past, present, and near-immediate future), the list includes Vista RC2, Exchange Server 2007 Beta 2 Help, Virtual PC 2007 Beta 1, and PowerShell RC2. All that and the happy announcement that Microsoft will soon be ending support for Windows XP Service Pack 1. (Is it my imagination or was that awfully quick?) October 5, 3:00 a.m. PDT Experts advise caution on implementing NAC Security researchers and experts this week cautioned network administrators to consider carefully whether they need to implement network access control (NAC) technology in their security infrastructure before buying in to the current hype surrounding it. September 22, 9:31 a.m. PDT More players announce NAC plans Microsoft and Cisco Systems played the role of proud parents on Sept. 6. But with so many questions about when NAC-NAP, as it’s been called, will be available, and how it will work with non-Windows clients and non-Cisco infrastructure, it’s been hard to figure out what the companies created. September 18, 3:00 a.m. PDT Cisco, Microsoft NAC plans leave many questions Building a bridge is rarely a quiet affair. Just ask John Augustus Roebling and his son, Washington, whose Brooklyn Bridge took 13 years to complete and cost 27 people their lives. September 11, 3:00 a.m. PDT Cisco banking on collaboration tools Triple plays are rare in baseball. But Cisco Systems CEO John Chambers plans to do one better Wednesday by promising to pull off a "quadruple play" in the networking business: incorporating data, voice, video, and mobile capabilities across its product lines. September 11, 3:00 a.m. PDT Cisco, Microsoft to announce NAC progress Cisco Systems and Microsoft will announce progress on a 2-year-old effort to link their separate technologies for network client health screening, commonly known as "network access control," according to sources familiar with the companies' plans. September 6, 7:15 a.m. PDT Lessons from the verticals Every industry presents unique challenges, where IT must marshal more than the usual chunk of resources to solve extreme headaches. That may mean walking out to the edge of grid computing to garner greater compute performance, or it may involve management challenges such as accommodating a mobile workforce or connecting hundreds of far-flung offices. The greater the problem to overcome, the greater the potential to learn from successful solutions. August 21, 3:00 a.m. PDT Juniper, Cisco focus on access control Although Cisco Systems began evangelizing the notion of NAC (network access control) in 2003, it took its time putting a NAC strategy together, allowing competitors and small startups to rush in to fill the void. The fuzzy NAC picture, however, is starting to snap into focus, with access control news from both Cisco and Juniper Networks in recent weeks. July 17, 3:00 a.m. PDT RSA confirms acquisition rumors RSA Security confirmed published rumors that it is in discussions to be acquired, but declined to reveal the companies with which it is negotiating. June 29, 3:00 a.m. PDT NAC appliances reveal who's rapping at your network door As the NAC (network access control) market matures, the solutions are becoming more sophisticated at identifying users and assessing the security compliance of host devices. Answering questions such as how snugly they fit into the existing infrastructure (is it a forklift upgrade?) and how well they qualify a device’s security compliance posture before admitting it to the network helps to separate the wheat from the chaff. June 2, 3:00 a.m. PDT Hack Tales: Keeping thin clients synced from coast to coast I once consulted for a medical-records company that was rolling out thin clients to nearly 50 offices around the United States. The goal was to build a large Citrix MetaFrame farm over WAN links to the main datacenter, which was located outside Boston, providing a Windows desktop for every user without dealing with hardware problems at each site. May 29, 3:00 a.m. PDT Hack Tales: Network auditing on a shoestring What do you do when the auditors are breathing down your neck, wanting to see an exhaustive report on the Windows network security of a 2,000-user network across eight sites? That’s easy. Break out a text editor and start writing some Perl. May 29, 3:00 a.m. PDT Determina pre-hacks applications against intruders Malicious hackers are constantly exploiting software vulnerabilities. Vendors and IT staff alike spend countless hours racing to update protection signatures and install patches before their exposed systems can be compromised. It’s a never-ending battle that favors the hackers. May 15, 3:00 a.m. PDT ConSentry locks down the network Traditionally, enterprise networks have been built on trust: Anyone connected is assumed to be authorized because they have to be on the premises. But the growing prevalence of wireless networks, remote access, and nonstaff workers have turned networks into easy targets. “The LAN is now the new DMZ,” says Tom Barsi, CEO of ConSentry. May 15, 3:00 a.m. PDT Product previews IBM primes x86 servers for consolidation IBM announced a new line of Intel x86 server hardware called System x that is designed to deliver enterprise class virtualization capabilities for server consolidation. IBM also unveiled the Consolidation Discovery and Analysis Tool (CDAT), software that scans the network for under-utilized servers and helps identify opportunities to consolidate and virtualize x86 systems. Three new models -- System x3950, System x3850, System x3800 -- will be available this month. System x3950, System x3850, System x3800, IBM May 8, 3:00 a.m. PDT RSA buys PassMark for $44 million RSA Security said on Monday that it acquired PassMark Security, a maker of lightweight authentication technology. April 24, 1:24 p.m. PDT Product previews NetSuite Flexes Process Automation, Woos Verticals Hosted applications vendor NetSuite announced NetSuite 11.0, its latest integrated CRM and back-office suite. The new version, due in May, extends AJAX (Asynchronous JavaScript and XML) beyond the current real-time dashboards into functional areas, including reporting, scheduling, and document management. It also adds complex process customization via a new scripting language, SuiteScript, built on JavaScript. The company also launched vertical editions of NetSuite for wholesale/distribution, services, and software companies. NetSuite 11.0, NetSuite April 17, 3:00 a.m. PDT Stupid user tricks: Eleven IT horror stories No matter how hard we pray, how many chickens we sacrifice, how often we chant naked by moonlight, every network is at one time or other exposed to the ultimate technology risk: users. April 13, 3:00 a.m. PDT RSA polishes its smart token system Branch offices aren’t always just nests for employees further down the food chain. Sometimes they comprise critical pieces of business infrastructure that are just geographically removed from HQ. Unfortunately, managing high-end authentication becomes troublesome when target nodes are distant from knowledgeable IT staff. April 6, 3:00 a.m. PDT Exclusive: ESP 2.0 boosts your network perception System admins used to only dream about knowing exactly which devices were on their network and controlling what resources those devices were accessing. There has been an explosion of products announced and released during the past few months aimed at providing this highly sought view of traffic flows and hosts, as well as tools to enforce network policies. One of the more mature solutions is ESP (Elemental Security Platform) 2.0. March 31, 3:00 a.m. PST The hidden challenges of federated identity For years, companies have kept stores of identity information about employees, customers, and partners. These databases and directories are critical components of a company’s identity infrastructure. But as businesses push to create new products and increase productivity, they have discovered that they often must cooperate to provide the services their customers and employees demand. March 24, 3:00 a.m. PST Scaling a federated identity infrastructure Different kinds of organizations approach the problem of scaling a federated identity implementation in different ways. When you’re federating with one or two partners, hammering out the legal arrangements and assigning risk and liability is done one partner at a time. Even if technology standards provide universal system interoperability, the lawyers are likely to approach each agreement as a one-off task. Let’s call this model “peer-to-peer federation.” March 24, 3:00 a.m. PST Product Previews Fujitsu unveils eight-socket server blade Fujitsu last week announced an eight-socket server blade based on dual-core AMD Opteron processors. Taking up a good chunk of a Primergy BX600 chassis -- which otherwise supports as many as 10 two-socket blades or five four-socket blades -- the Primergy BX630 can be installed alongside one or two other blades running AMD Opteron or Intel Xeon processors. The eight-socket BX630 blades will be available in the second quarter of this year, priced at less than $36,000. Windows Server 2003, Red Hat Enterprise Linux, Suse Linux Enterprise Server, and VMware ESX Server operating systems are supported. Primergy BX630, Fujitsu Computer Systems March 20, 3:00 a.m. PST It takes an extraprise to secure your business Back in May, I wrote a column about our country's lack of an overall plan to protect critical infrastructure in case of attack -- telecommunications and fiber in particular. Consider this Part 2. February 21, 3:00 a.m. PST Cisco appoints ex-MCI chief Capellas to board Cisco Systems Inc. has appointed Michael Capellas, former president and chief executive officer of MCI Inc., to its board of directors, the computer networking company said Tuesday. February 1, 4:42 a.m. PST Juniper sues over message-board posts Juniper Networks Inc. is suing 10 unnamed defendants over comments posted to a networking news message board that Juniper charges are libelous. December 22, 4:27 a.m. PST Hardware isn't enough IT buyers live in a golden age of commodity hardware. Processors, servers, networks, storage, you name it: Every segment of the IT stack keeps getting faster, cheaper, and more commoditized. No surprise, then, that IT managers often resort to a checkbook-waving strategy, throwing hardware at every IT problem, from a balky WAN to an application speed bump. November 28, 3:00 a.m. PST No. 13: 'My cable modem is faster' A shared T1 was once immeasurably fast to most folks. Now, it’s less than half the bandwidth most of us have at home. November 28, 3:00 a.m. PST No. 1: It’s probably not the servers Server upgrades used to make all the difference, which is why the old saw "When all else fails, throw more hardware at it" persists today. That's still true in some cases. But how much of IT is really that compute-intensive? Generally, you can save a lot of time and money by turning your hairy eyeball away from server hardware. The lower end of the server spectrum has more than enough horsepower to handle everyday tasks. November 28, 3:00 a.m. PST EU seeks to limit data retention rules to one year Members of the European Parliament's civil liberties committee voted on Thursday to limit to 12 months the maximum period for which telephone companies and ISPs (Internet service providers) should store call data logs. November 25, 12:00 a.m. PST Network policing at wire speed The new line of LANenforcer products from Nevis Networks takes a hardware-based approach to network user access and policy enforcement. Based on Nevis’ “massively parallel” LANsecure architecture, LANenforcer is designed to provide a “personal DMZ” around each network user by combining comprehensive access control with defense against both known and unknown threats. November 21, 3:00 a.m. PST Exclusive: ConSentry keeps a watchful eye on users Network security is going through a paradigm shift. It is no longer enough to secure just the network edge against unknown attackers trying to break in; traffic inside the network must come under increased scrutiny, as well, to ensure that users are following established policy or meeting regulatory requirements. And when users misbehave, there must be a way to enforce the policy by denying access to sites, applications, and protocols. November 14, 3:00 a.m. PST HP makes push for network stability These days, network stability means more than just making sure links are available and the proper routes are in place. A single workstation on a network segment can easily wreak havoc following a virus or worm infection, as continuous attempts to infect neighboring systems consumes enormous bandwidth on the LAN — and eventually the WAN or Internet circuit. November 7, 3:00 a.m. PST Federation takes identity to the next level When clients of advertising giant Ogilvy & Mather want to collaborate on budgets or watch rough cuts of commercials, they’re likely to log on to the company’s network and do it online. The process speeds delivery and saves on travel costs, but it can also add a big security and regulatory burden. October 7, 3:00 a.m. PDT Open source identity A complete identity management solution comprises a number of components. As such, it would be difficult for any single open source project to offer a plug-and-play identity management system. There are, however, a number of projects that offer components of such a system, particularly in the area of federation and SSO (single sign-on). August 8, 5:00 a.m. PDT Open source directory With more and more companies investigating capabilities such as identity management, SSO (single sign-on), and automated provisioning, directory services are fast becoming a vital component of network infrastructures. So far, however, no open source project has gained as much traction in this area as Apache enjoys in the Web server market. August 8, 5:00 a.m. PDT Cisco mulls acquiring Nokia, report says Internet equipment maker Cisco Systems Inc. is interested in acquiring Nokia Corp., the world largest manufacturer of mobile phones, according to several media reports citing the Sunday Business newspaper. August 8, 3:58 a.m. PDT The dumb remote office Management, compliance, and security concerns have made consolidation all the rage in large organizations, which have increasingly moved their applications and data from globally dispersed servers to a few centralized, tightly secured data centers. With the trend toward intelligent networks, we may one day see remote offices with very little intelligence of their own. July 18, 5:00 a.m. PDT Building the intelligent network The days of the fat, dumb pipe, are over. Servers applications, and storage have been shouldering the intelligence and security burden for too long. It’s time for the network infrastructure itself to add some smarts. After all, when it comes to intelligence, the real beauty of the network is that it touches everything. July 18, 5:00 a.m. PDT Cisco adds Intelligence to network gear Embarking on a new path, Cisco Systems unveiled details of its first move into the messaging middleware business last week, with its AON (Application-Oriented Network) business unit. June 27, 9:00 a.m. PDT VMware debuts ISV network June 6, 9:20 a.m. PDT Investigators link Cisco hack to other activities A theft of computer source code from Cisco Systems, reported a year ago, has led to a wide-ranging investigation of potential criminal activity involving multiple server break-ins in several countries, according to the U.S. Federal Bureau of Investigation (FBI). May 10, 9:44 a.m. PDT Juniper adds to network toolkit Juniper Networks signed definitive agreements Tuesday to acquire Peribit Networks and Redline Networks. The two acquisitions give Juniper additional products in the network application delivery and performance space. April 26, 3:18 p.m. PDT Stock your Windows administration toolkit for free I'm test-driving the freeware version of AVG's Anti-Virus 7.0, and so far my hat's off. Not only does it seem as up-to-date as Symantec, it's definitely got less of a dragging impact on system resources. Before you get your hopes up, however, the free version of AVG's tool is slated solely for single-PC home-oriented use. Business accounts still must pay. February 25, 3:00 p.m. PST SSL VPNs come of age Traditionally, providing road warriors and business partners with access to back-end servers and resources has meant deploying an IPSec VPN. For site-to-site communication, IPSec remains the only game in town, but for client-to-enterprise links, it is falling out of favor precipitously. The administrative overhead associated with deploying IPSec client software has become overwhelming given the ever increasing number of clients to support. There is also the potential that IPSec tunneling will allow an untrusted device to punch a hole through the firewall -- and directly into the heart of the network. February 4, 3:00 p.m. PST Hands across the enterprise Viewed as a pipe dream only a few years ago, the “autonomous datacenter” gained momentum in 2004, leading some to claim IT as we know it will be dead within a decade. But that’s obvious, isn’t it? In 1994, Usenet was still useful, and Spam tasted great at 1 a.m. The question remains, How soon will we get there -- and who’s behind the wheel? December 30, 3:00 p.m. PST IBM releases Tivoli updates for Cisco NAC IBM plans to release updates to two products that tighten integration between its Tivoli product and Cisco Systems' Network Admission Control (NAC) technology, according to a statement from the company.

November 30, 5:38 p.m. PST The top 20 IT mistakes to avoid We all like to think we learn from mistakes, whether our own or others’. So in theory, the more serious bloopers you know about, the less likely you are to be under the bright light of interrogation, explaining how you managed to screw up big-time. That’s why we put out an all-points bulletin to IT managers and vendors everywhere: For the good of humanity, tell us about the gotchas that have gotten you, so others can avoid them. November 19, 3:00 p.m. PST Sybari offers security for IM, SharePoint Sybari Software today added Antigen 8.0 for Microsoft SharePoint and Antigen 8.0 for Instant Messaging, two antivirus, antispam, and content-filtering security software products for enterprise environments. November 18, 4:09 p.m. PST The ever-changing network It could be called the “ignomoment;” the split second following a definitive action when you realize you've just made a tragic mistake. For network administrators, this means the difference between going home at 5 p.m. or 5 a.m. The truth is, despite incidents of careless backhoe drivers pulling up fiber bundles or hurricanes bringing down the power lines, administrator error is the most common reason that a network fails. November 5, 3:00 p.m. PST Cisco, Microsoft bridge security gap Cisco Systems Inc. and Microsoft Corp. on Monday will announce a collaborative effort designed to bridge a divide between their emerging network access-control architectures.

April 27, 12:48 p.m. PDT Exclusive: Oblix’s ShareID 2.0 a first-rate authentication middleman Although it’s not common practice for a company to grant internal network-resource access to employees of another company, it’s not unheard of either. The problem with the practice lies in authentication management. When a business partner requires access to certain resources, the unfortunately common solution is to create accounts for specific employees of the partner within the local directory. Although there are ways to manage this access, maintaining these user accounts is not in the best interest of any IT department, for both security and maintenance reasons. Oblix has just announced ShareID 2.0, a product that aims to fill this gap by providing a means for managing resource access between cooperating entities without the risks. April 23, 3:00 p.m. PDT Cisco warns of more critical software holes Cisco Systems Inc. warned its customers about two critical security holes that affect almost every product the company makes.

It also means that your applications can’t be hijacked to send sensitive data to places it shouldn’t go. March 5, 3:00 p.m. PST SSL VPNs best IPSec rivals As as one of their many challenges, IT staffs must provide secure remote access to data and applications from outside the confines of the enterprise. IPSec-style VPNs are no longer up to the task, however. IPSec is just too inflexible and limited in device support to really work in many situations.
