Firewall maker Check Point launched a security appliance on Tuesday that it claims will protect corporate networks from cyberattacks that exploit known vulnerabilities in LAN protocols and applications.
The InterSpect appliance works by having access to a regularly updated database of known vulnerabilities. When packets associated with a particular application start acting suspiciously, the InerSpect appliance takes over, quarantines the affected PC and warns the user that all network access has been temporarily revoked while the computer is being cleaned.
Computer security experts fear a new worm that began spreading rapidly across Australian e-mail networks on Sunday could be a rehearsal for a more concerted attack in coming weeks.
The worm — dubbed Bagle-A — carries an expiry date, possibly indicating more robust versions of the worm could be slated for release soon, said Daniel Zatz, security director for Computer Associates Australia.
Microsoft is still investigating which of its products are vulnerable to a bug in its implementation of the H.323 voice over IP (VoIP) standard.
While the company has patched its Internet Security and Acceleration server software against the glitch, it has conceded that users of the company's NetMeeting software are probably vulnerable to buffer overflow bugs found in implementations of the protocol that could allow a remote attacker to take control of affected systems.
As the European Commission (EC) is preparing to launch the world's first IPv6 network this week, one respected commentator predicts that the new standard will make the internet less secure and slow it down by letting many more devices connect.
At an event in Brussels this week, the EC will launch the new Global IPv6 Service, designed for the research community. Announcing the network, Erkki Liikanen, commissioner for enterprise and the information society, said, "[IPv6] is a crucial component for e-Europe and faster rollout of broadband networks."
Corporations are embracing a simpler, cheaper way of connecting remote workers to their networks, opening up new opportunities -- and competition -- for network security vendors.
At stake are gateways allowing secure access to corporate networks based on a browser security technology known as Secure Sockets Layer (SSL) encryption. Analysts and makers of SSL-based networking equipment say that large numbers of corporate users are starting to implement virtual private networks (VPNs) using SSL technology.
