The FBI is warning of a vulnerability in an open-source toolkit used to make VoIP calls. The mobile, wireless world in which we now live has created a shift in the focus of venture capital investments in security technology. Today's investors tend to target technology that directly protects people and information, a marked change from a few years ago when the focus was the protection of corporate computer systems as a whole. Variants of the Rinbot worm are exploiting the Windows Server DNS Service vulnerability, researchers said today. A Pennsylvania hospital has extended its systems boundaries by providing staff with remote secure access This is one of a series of articles where I will try to encourage everyone who reads them to finally get serious about establishing an employee awareness training program. The good news is that over the past several years, security analysis has become a widely accepted and integral part of development and deployment processes. Hackers have thousands of different ways to access or exploit computing environments. It would be nice if most intrusions were detected, but they are not. It’s the 15th century, and wireless communications are flourishing. The Cardinal, Sir Dickcheney, sensing imminent invasion from the enemy, has instructed his trusted servant Walker (for centuries known only as “W”) to deliver a message to a military outpost on the remote frontiers of the kingdom, 500 miles away. “Prepare to attack.” reads the message. W’s problem: he has to get it there in 24 hours. His only option: wireless. He runs up to the tower where the master pigeon trainer, Rummy, awaits. They exchange a secret password and W hands Rummy the message. Rummy affixes the message to one of the prize pigeons and off it flies.

The principle of Xiscan is a good one. It takes the idea of war dialing software, which hackers have used to their advantage for many years to scan telephone networks in an attempt to locate entry points, and turns it against the enemy.
Xiscan works in the same way that the hackers have always used automated telephone dialers – to probe for weaknesses in the network. The difference is that it is designed to be used within the network, to locate rogue modems and bring users to heel.
The basic idea is that if hackers can use automated dialers to gain an advantage over legitimate users, then why can't the legitimate user do the same? It is a very good question – and there is something very satisfying about the idea of wrestling control of hacker-type tools, and using them for legitimate ends. Xiscan takes the wardialer idea and turns it on its head, using it as a way to monitor the network from within.

Sometimes dialing into access data just isn't enough, and NetOp Remote Control allows remote access for the control of multiple PCs. This allows users to remotely initiate work from a distant location on their office workstation, enabling work to continue when they are unable to physically be at their desk. It can also provide useful and cost-efficient support from administration for problem solving, staff training and observation, or simply data use, all rolled into one.

NetOp Remote Control secures the communication while allowing authorized access. Controlling a keyboard and mouse, and viewing the screen of a remote computer is made easy with this solution, which makes an ideal tool for administration and management purposes wherever the skilled user is located. This means that a business can employ an expert at one location, but the enterprise can benefit from his or her expertise in branch offices no matter how diverse they may be ­ geographically.
