The decision to deploy proprietary, rather than open source security solutions (OSS), is often influenced by some commonly held perceptions.
Many IT professionals can’t seem to shake off the belief that OSS is inherently risky unreliable and complex. I am going to examine the most common of these perceptions to highlight how the facts are very often the exact opposite to what people believe....[more].

May 13, 2008:
FBI Issues Warning About Vulnerability of Wi-Fi Hotspots
|
[0 comment(s)]

|
The FBI issued an alert this week warning that wireless Internet networks, often called Wi-Fi hotspots, are more vulnerable to hackers than most users probably realize. In South Florida, Wi-Fi hotspots are at airports, fast food restaurants, bookstores, coffee shops, sports bars, school campuses, malls, supermarkets -- just about everywhere. Several cities and neighborhoods in the region plan to eventually install networks for residents, too....[more].

May 12, 2008: Researchers Dig Into x86 Chips For Stealthier Rootkits
|

Security researchers have discovered a new technique for developing rootkits, malicious packages used to hide the presence of malware on compromised systems.
Instead of hiding a rootkit in the virtualisation layer, Shawn Embleton and Sherri Sparks of Clear Hat Consulting have discovered an approach for smuggling rootkit technology into System Management Mode (SMM), an isolated memory and execution environment supported in Intel chips that's designed to handle problems such as memory errors and the like....[more].

One day in May 2005, a 16-year-old hacker named SoBe opened his front door to find a swarm of FBI agents descending on his family's three-story house in Boca Raton, Florida. With an arm and leg in casts from a recent motorcycle accident, one agent grabbed his good arm while others seized thousands of dollars worth of computers, video game consoles and other electronics. His parents looked on.
At that moment, some 2,700 miles away, in the Los Angeles suburb of Downey, California, the FBI was serving a separate search warrant on Jeanson James Ancheta, SoBe's 20-year-old employer and hacking mentor. It was the second time in six months Ancheta had been raided by the FBI - a clear sign, had either bothered to notice, that their year-long botnet spree was unravelling....[more].

Google has thrown its weight behind a fledgling security reporting group for the open-source community.
The search engine giant, long a proponent of open-source software, is now one of three sponsors of oCERT, the Open Source Computer Emergency Response Team....[more].

Configuring Samba for your office or home can provide many advantages. By encouraging users to store files on a central file server, you can simplify data backup and in some cases, software installation and maintenance.
Unfortunately, the initial configuration of Samba can be tricky. Many simple steps need to be executed in the correct order, and one small slip up can have big repercussions. This chapter explores the ways in which you can recover from those mistakes that you couldn't avoid....[more].

May 05, 2008: Virtual Server Sprawl Highlights Security Concerns

Think server sprawl is bad now? Just wait till you experience virtual server sprawl. When users can clone a virtual machine with the click of a mouse, or save versions of applications and operating systems for later use, you're asking for trouble if IT doesn't maintain tight control, virtualization management vendor Embotics warned in a session at Interop Las Vegas Tuesday. (Look through our slideshow at other products shown at Interop.)
The ease of creating and deploying virtual machines can lead to a nightmare of confusion when it comes to IT maintenance. How do you keep track of hundreds of VMs scattered about your network, all with varying operating systems and applications installed? How do you know which ones are securely patched and what other servers they can access? Read on for an overview of this growing problem and let us know what solutions you may have for virtual server sprawl....[more].

On that day in 1978, 393 Arpanet subscribers were sent what's reckoned to be the first ever spam email1 in history (the message itself was written on 1 May 1978). DEC marketing rep Gary Thuerk came up with the wheeze which produced a fierce backlash from Arpanet (military) administrators, as well as a small number of sales.
After first appearing on Arpanet, unsolicited bulk commercial ads moved over to Usenet, email and websites links. Much to the chagrin of Hormel Foods, the term spam was applied to the phenomenon in a pop-culture reference to the spam skit from Monty Python's Flying Circus, where all meals in a restaurant come with spam, spam and more spam. Junk email - not nourishing luncheon meat - has become the principal meaning of the word spam....[more].

Forget networked PCs or even PlayStation 3s, components commonly found in plasma TVs are the latest thing in password cracking tools.
High performance FPGA (Field Programmable Gate Array) chips are the Chuck Norris of number crunching, equally suited to image processing and (with a bit of modification) password cracking....[more].

About a year ago, we took a look at the growing trend toward open-source security and highlighted 10 of the best apps available. Since then, the area has continued to mature, and now we're back highlighting 75 of the most frequently downloaded open-source security applications.
We all love lists, especially if they have to do with something we care actually care about! See if your "weapon of choice" made this particular list!...[more].
