Security Forecasts for 2011

What will 2011 hold for information security professionals? Last year I predicted a year of change. It did not happen. But we are incubating a major crisis: legacy systems are vulnerable; existing security technologies are breaking down; a dangerous monoculture is building; and an information tsunami is heading our way.

Today's security solutions will not meet tomorrow's demands. The longer we put off change, the greater the potential damage from a major incident. The security community is slow to react to a changing problem space, however, preferring gradual evolution to radical revolution. So don't hold your breath. Nevertheless, I expect to see three major shifts in thinking during 2011.

The first is that we are likely to experience a major security incident involving the integrity of our critical national infrastructure. Not quite Die Hard 4 perhaps, but sufficient to incentivise utility companies to tackle their long-standing security vulnerabilities. Building security into the systems development cycle will need to be taken out of the "too difficult" box. The long haul towards building acceptably secure information systems will begin.    

Ubuntu 'trusted client' secures Windows and Citrix

Trusted Client, an Ubuntu-based encrypted clean boot utility, has received its Common Criteria certification and been included in the Defence Signals Directorate Evaluated Product List.

The device is designed to allow secure and safe access to a corporate or government network - even if the host machine is infected with malware.

Developed by UK-based encryption specialist Becrypt, Trusted Client is a hardened version of Ubuntu 9.04 that has been cut down to its bare components - about 500mb - and then bundled with Windows deployment tools. This is all wrapped in a layer of encryption and deployed on a standard USB drive.

David Jones, senior product consultant at Becrypt explained that in order to bypass any malware on an untrusted PC, users just boot from the Trusted Client memory stick. The PC then requests a username and password before loading Ubuntu.

The potentially infected hard drive is completely ignored.

"We boot the machine from the USB stick so you come from a known clean starting point. We never allow users to see the hard drive, we never touch it - we assume it is dirty. Instead we use the available RAM on the machine as our work area.

Beware Stuxnet Impact On Windows 7

Stuxnet threat not only to shadow the user's computer with a system of 'supervisorycontrol and data acquisition "(SCADA), which is widely used in oil and gascompanies. Windows 7 and Vista users will also need to be alert.

The first threat, Alfons said, the victim Stuxnet so can not store data or run certain programs. This is because disk space is reduced due to swelling Winsta file.

Then, he went on, the computer may hang or slow. Plus the network connection thatcan be disconnected.

That's because Stuxnet perform injection on some Windows system files. Includessvchost.exe, which is associated with a network connection, as well as relatedlsass.exe computer activity.

Antivirus Software, Free Online Virus Scan

The free antivirus programs listed on this page allow you to detect computer viruses, remove or repair infected files, prevent infection, detect and remove email viruses, etc. There are also free online virus scanning services available for those who prefer (or need to) scan for virus that way.

Note that a number of the free antivirus software listed have limited support for scanning spyware and other types of non-virus malware that their commercial equivalents provide. If you are looking for commercial antivirus software, one that comes highly recommended by security-conscious people is the Avira Antivir Premium  (which is very light on resources and consistently has a very high detection rate). Also popular among many computer users is Norton Antivirus,  which also has a Mac OS X version.
