Managing WLAN Risks With Vulnerability Assessment
AirMagnet, October 2005

Many measures are available to safeguard WLANs, but which should your company deploy, and how can you tell whether your network has been sufficiently hardened? This white paper, written by Lisa Phifer for AirMagnet, describes an iterative process for vulnerability assessment, risk analysis, and remediation.

Chasing away your wireless blues
searchMobileComputing, November 17, 2005

While Wi-Fi security has been grabbing headlines, Bluetooth has been creeping quietly into corporate networks, under IT's security radar. Given increasing deployment and broader usage, Bluetooth really deserves more attention. In this WLAN Advisor column, Lisa Phifer describes Bluetooth attacks and monitoring tools.

Show me the money: WLAN ROI
searchMobileComputing, September 20, 2005

If your company hasn't yet jumped on the Wi-Fi band-wagon, or seems to be stuck at the pilot stage, projecting ROI may help you turn the crank on broader wireless deployment. Doing so may also highlight financial differences between WLAN design alternatives. In this Wireless Advisor column, Lisa Phifer explains why it's important to examine the 'soft' benefits as well as the 'hard' ROI of WLANs.

Beware phone phishers bearing false gifts
MobilityLoop, November 21, 2005

In this MobilityLoop column, Lisa Phifer discusses how phishers have been capitalizing on Skype's popularity to plant IRCbot trojans that pose as Skype software, and why P2P programs like Skype are so often targeted by phishing email.

SSID Broadcasts and Other Security Legends
MobilityLoop, October 31, 2005

You've probably hear this old chestnut: disable SSID broadcasts to hide your WLAN from war drivers. But disabling SSID broadcasts will not accomplish that feat -- doing so will make your WLAN harder for legitimate users to access, and increase overhead. Lisa Phifer discusses why in this MobilityLoop column.

Here, There, but still not Everywhere
MobilityLoop, October 18, 2005

While hotspot locations and roaming agreements are expanding, the cold hard truth is that Wi-Fi does not (yet) offer anywhere-anytime mobile access. Carriers ask us to believe that 3G wireless services are a better answer, but is this only a vision or reality? In this column, Lisa Phifer ponders the gap between Wi-Fi and 3G wireless.

Lessons from the NWW security tour
Network World, October 17, 2005

You can't police and enforce a security policy that doesn't exist, and more often than not companies are missing this key resource. That was one of the core messages delivered by CoreCom's Dave Piscitello on the recently completed Network World Security Technology Tour, wrote John Dix in this NWW editorial.

Wireless LANs, the new 'secure' network
searchNetworking.com, October 27, 2005

Once considered a playground for hackers and malicious attacks, are wireless networks becoming more secure than their wired counterparts? TechTarget's news writer Andrew Hickey ponders this question by chatting with WLAN security experts, including CoreCom's Lisa Phifer.

Phishers using SSL certificates
Dave's Blog, 28 Oct 2005

In this post, Dave observes that phishers don't need to bother purchasing a server certificate from a trusted authority to create a sufficiently convincing lure to extract customer account info from their victims.

Do you trust your online banking home page?
Dave's Blog, 26 Oct 2005

And has your bank made it impossible for you to do so? Dave ponders how customers can trust that they have really visited their bank's home page and not that of a phisher, without confirming the site's server certificate.

University security on a limited budget
Dave's Blog, 19 Oct 2005

In this post, Dave answers another question from the NWW Security Tour 2005: Our college has a limited budget for security. With threats at so many levels, would it be prudent to focus on one specific vector (i.e., email, apps, web, firewall/IDS/IPS)?
