3 Approaches to Identifying Mobile Devices

February 24, 2012 By Editor Leave a Comment

When it comes to managing wireless devices on your network, you’ve got two basic options: treat the device as a known entity that is allowed to access the corporate network, or as an unknown entity that is not. But there are several ways to make that determination, says Chris Williams, a systems engineer with Carousel Industries, and they are progressively more granular and useful. Fingerprinting and Web Browser Snooping The simplest way to identify a device is through fingerprinting or web browser snooping. With fingerprinting, when the device logs on, it performs a DHCP request. In that request is a… Continue Reading ›

Survey Points to Serious Issues with Firewall Management and Compliance

December 8, 2011 By Editor Leave a Comment

With the furious rise in cybercrime, well maintained and audited network firewalls are a critical line of defense. However, firewalls are apparently spinning out of the control of IT, at least according to a recent survey by Tufin Technologies, which makes software for automating security processes. Given the source you are free to take the survey results with a grain of salt, but if there’s even a modicum of truth to the survey, it points to some real problems. Firewall change management is a sticking point For starters, 67% of the 100 network security professionals surveyed, all of whom… Continue Reading ›

Meeting the Security Challenges of Educational Institutions

November 14, 2011 By Editor Leave a Comment

For security professionals, educational institutions present a number of challenges that are quite different from the corporate world. It’s an environment with distinct user groups – students, faculty and staff – that require both separation from one another and the ability to collaborate. In K-12 schools, there’s a need to police Internet access. In universities, there is the need to monitor and log traffic and usage. And many institutions have to comply with standards such as PCI and HIPAA, if they take credit cards and store student health data. To get a handle on how schools are dealing with these… Continue Reading ›

Data Security Breach Roundup

June 30, 2011 By Editor Leave a Comment

Groupon hack reveals 300,000 email addresses and passwords This is a case of an IT security breach handled well. The Indian Groupon subsidiary Sosata.com accidentally published a list of some 300,000 subscriber email addresses, complete with their Sosata.com passwords. The list was discovered by security expert Daniel Grzelak, who runs the web site, shouldichangemypassword.com. Grzelak is one of the good guys. He collects info onemail addresses known to be compromised and posts them on his site in hopes the owners will find them and, as his URL suggests, change their passwords. As he told Risky.Biz: The shouldichangemypassword.com database includes leaked… Continue Reading ›

Data Security Breach News Roundup

June 1, 2011 By Editor Leave a Comment

The hits keep coming and (perhaps not surprisingly) the targets are the big boys. In the last month we have seen the first serious repercussions of the RSA Security Breach, the havoc that can happen when hackers don’t like how a media outlet tells a story, and Honda having to get let 280,000 Canadian customers know that their personal information was stolen. Lockheed Martin Breached with Duplicate RSA Electronic Security Keys In an ominious attack and a potential foreshadowing of things to come, massive defense contractor Lockheed Martin’s network was breached according to the news agency Reuters: According to the… Continue Reading ›

Government says Mobile Devices, Corporations key targets of organized, sophisticated Cybercriminals

May 12, 2011 By Editor Leave a Comment

In compelling (at least for a computer security geek) testimony delivered before Congress earlier this week, Assistant Attorney General Jason Weinstein spoke to the privacy and security threats facing US citizens and corporations from the Department of Justice’s perspective. His comments focused on the explosive growth of mobile devices (smartphones and tablets) and the security risks these devices face from what he describes as “organized, international, profit-driven cybercriminals”. He continues: “Every day, criminals hunt for our personal and financial data so that they can use it to commit fraud or sell it to other criminals. The technology revolution has facilitated… Continue Reading ›

May 11, 2011 By Editor 2 Comments

The modern workforce is evolving, with more and more employees working from home or small branch locations. While setting up a campus with a secure Wireless Network is becoming a well-understood exercise the question becomes, how are businesses extending the security and control they are used to in a campus setting to the many remote and teleworkers they need to support? According to Chris Williams, one of Carousel’s wireless networking specialists, one solution that has been taking off with businesses looking to address this challenge is the deployment of wireless Remote Access Points, or RAPs.

Never in my wildest dreams did I think that I would have something in common with stock market watchdog theStreet. Much to my surprise, I do! TheStreet just came out with an article on the “5 Cisco Alternatives“, Juniper, Aruba, Polycom, Riverbed and Fortinet, all five of which Carousel represents, and I talk with customers about on a daily basis. TheStreet has noticed a trend that I have personally been seeing as well, “best of breed” is becoming more important than “brand name”. TheStreet’s five technology picks to watch out for are Juniper Networks, Riverbed, Polycom, Aruba Networks and Fortinet. … Continue Reading ›
