Fear of insider threats hits home The more money that companies spend on securing their IT operations from external attack, the more it seems they become aware that the potential threat posed by their own employees remains their most significant risk. HP core LAN switch signals rise of ProCurve Hewlett-Packard isn't yet a household name in enterprise LANs but is poised to extend its gains against leader Cisco with a new core switch and coordination with HP's consulting arm. September 10, 2:53 p.m. PDT Best of open source in networking If we had to pick the most significant trend in networking today, the VoIP phenomenon might well top the list. And open source is playing no small part. While enterprises remain reluctant to rip out their tried-and-true PBXes, open source VoIP -- usually in the form of Asterisk -- is capturing business communications one small business or branch office at a time. Sooner or later, enterprises too will catch the open source VoIP bug. The cost savings and flexibility are too compelling to resist.  September 10, 3:00 a.m. PDT Sourcefire acquires ClamAV open-source anti-malware project Network security specialist Sourcefire announced Friday that it has acquired ClamAV, an open-source gateway anti-malware project whose technologies are used in the products of a number of other vendors. August 17, 8:58 a.m. PDT IEEE group settles on faster Ethernet plans A technical group working on the next generation of Ethernet has agreed to disagree and will now work on a single standard that covers both 40Gbps and 100Gbps speeds. July 24, 4:36 a.m. PDT Novell to manage Windows desktops with Zenworks Novell hopes to cut out some of the complexity small and medium-size businesses face in managing Windows desktops with new software it is demonstrating at CeBIT in Hanover, Germany, this week. March 15, 9:16 a.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 unveils branch-office strategy Enterprises have done wonders in recent years consolidating their IT operations into efficient and tightly managed datacenters. That trend has been a godsend for system administrators and IT workers, who no longer have to spend long hours on the road, in transit to far-flung branch offices to reboot servers and take care of other mundane tasks. One population that hasn’t benefitted from centralized IT operations: the poor souls who have to work in those branch offices and live at the mercy of their WAN connection. And that’s no small population. By one estimate, as much as 80 percent of employees at many companies now work outside of headquarters. October 30, 3:00 a.m. PST 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 Huawei to expand R&D in India Chinese networking equipment maker Huawei Technologies Co. is expanding its R&D (research and development) in India with a new center in Bangalore for the development of optical network products and wireless LAN technologies. August 31, 8:08 a.m. PDT Slow progress for 802.11n standards The IEEE 802.11n standard has been three years in the making, and from the looks of it, it has at least another year to go. That’s a shame because it offers a lot of benefits, including higher throughput than the current Wi-Fi standard -- about 120Mbps in the real world -- and 50 percent longer range. Plus, because it uses multiple antennas that can stitch together a fractured signal, it eliminates a lot of spots where there might be drop-offs indoors. June 6, 3:00 a.m. PDT InfoWorld’s CTO 25 winners have the right stuff Five years in, and the quality keeps improving. I’m talking about InfoWorld’s CTO 25 award winners, our annual crop of high achievers who have pushed their companies’ IT efforts to new heights over the past year. In this incarnation of the awards, not only did we see a record number of nominees, but we were bowled over by the qualifications and the sheer accomplishments of so many of the candidates. Read the highly distilled results of that embarrassment of riches -- a collection of 25 profiles. June 5, 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 Hack Tales: Air-gap networking for the price of a pair of sneakers Federal IT managers face troubling times when it comes to synchronizing an air-gap network. And just in case you’re thinking “air gap” refers to a new brand of sneakers … well, you’re almost right. May 29, 3:00 a.m. PDT Nortel, Symantec team on app security Symantec plans to announce Monday a deal to put its intrusion prevention system (IPS) software on Nortel Network's application switching hardware. May 22, 8:50 a.m. PDT Gigamon offers one view of many monitoring systems Compliance requirements, security threats, and the need for operational visibility require more and more monitoring of activities on the network. Vendors have responded by offering plug-and-play appliances to fill specific needs, yet nobody wants to manage a patchwork of one-off solutions, each with its own proprietary spin. “At some point, the customer is going to get tired of all this. They’ll want help to aggregate the monitoring,” says Denny Miu, CEO of Gigamon. May 15, 3:00 a.m. PDT Interop shows slow, steady progress on NAC Network access control was a hot topic at last year’s Interop show, despite an evolutionary state that was barely protozoic. But new developments from the Trusted Computing Group (TCG) and pure-play vendors such as Vernier and InfoExpress could soon enable the technology to crawl out of the muck and take its place on enterprise networks, according to one expert. May 1, 3:00 a.m. PDT Cisco sets up R&D lab in Hanoi Cisco Systems has teamed up with Hanoi University of Technology (HUT) to open a research and development (R&D) lab in Vietnam, the company said Friday. April 21, 4:29 a.m. PDT Dark tales from your friendly IT help desk The features I normally tend to write for InfoWorld are … well, let’s call them "technically thick" … somewhat dense studies in micro- and macro-IT management issues. Good reads if your life revolves around these things, but not exactly where you’d look for a barrel of laughs. But there’s an exception to every rule. April 20, 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.
