The Instant Virtual Extranet (IVE) Access 3000 from Neoteris is a hardware/software hybrid SSL VPN appliance that offers users access to network resources securely. These resources also encompass web-enabled applications and email software (Lotus Notes and Microsoft Exchange), as well as Unix file shares.

Accomplished hackers will always perform some sort of reconnaissance on a target network before mounting an attack - finding out details such as operating system types, application version, etc. The idea behind ActiveScout is that if the application can detect this activity it can later prevent it. Bogus host or port data traffic is marked, and the application responds to any future activity it thinks is coming from an attacker with such marked data. It then blocks the packets and stops any damage ever occurring.

The U.S. Department of Homeland Security failed to meet user needs or to conduct enough security testing by rushing development of a secure network for sensitive data, according to a report by the DHS inspector general. Intrusion prevention firm Network Associates is to release its latest version of a managed firewall for end-users, McAfee Desktop Firewall AsaP. Wireless security firm SonicWALL is to sell a virtual private network (VPN) and firewall software solution for mobile employees. Frequently, the media characterizes computer crimes as those involving hacking (gaining unauthorized computer network access), cracking (another word for gaining unauthorized access to a computer or program), or web page defacing (gaining unauthorized access to a web page and changing its content).

When considering security in any area, be it IT, ATMs or even opening your own front door, there is always one weak spot: it has to involve people. Despite all the research, we are years away from being able to recognize a person's identity with 100 per cent certainty (even if using finger-printing, retinal scanning or DNA testing) in real time.
Unfortunately, the drive to encourage remote working means that more and more people need access to the corporate network, with all of the security risks that that entails: how can you be sure who the person is on the other end? One solution - or rather, preventative measure - is to simply publish only necessary information on an extranet, but even then, this can still be confidential data and a risky business.

This solution is supplied as software, desktop or rack-mounted. Each network sensor is a separate appliance, handing high-availability, high-security 10/100 or gigabit monitored segments.Running on a hardened OS, based on Red Hat Linux, in a small installation it can be managed using a web-based interface, software or optionally as an appliance.

Internet usage is growing at an accelerating pace.

This inventory application uses a technology called Lanprobe to meter software usage and discover devices on a network.
