Researchers Develop Scanner For Cloud Services

Researchers at two British universities have developed a scanner to prevent criminals steal confidential files in the cloud and upload illegal files to cloud services. The system is called Xdet , which stands for Extrusion detection.

Xdet makes a signature of private files and store them. The signature is then compared with the signatures of files exchanged with the cloud service. "This way, unauthorized uploads or downloads of potentially confidential data can be detected and prevented," the researchers compared ScienceDaily . Who argue that even upload illegal files to the cloud in this way can be noticed.

The Xdet software is placed between the cloud server and distributed file storage, instead of the perimeter of the cloud network. This has several advantages. So Xdet itself is protected by perimeter security solutions such as firewalls and IDS.In addition, it is scalable, and better in this way can the cloud provider to use network-based encryption to protect data during transport.

ESET & Facebook Works Together To Fight Against Malware

To protect users from malware, Facebook has signed a cooperation agreement with ESET's online virus scanner and will of the Slovak anti-virus company now offer to users. The online virus scanner is to start directly from Facebook.

"We have cooperated with ESET to add their security software directly to our detection and prevention systems, just as we did earlier this year with the other providers," says Facebook engineer Chetan Gowda. Facebook previously signed a similar agreement with the Finnish F-Secure and Japanese Trend Micro online virus scanners which were already integrated into Facebook.

If the computer of a Facebook user behaves erratically and shows signs of a malware infection, a message appears that an online virus scan is offered. Then, the user can perform the scan, the results and remove malware without the need to first log out of Facebook.

According Gowda help the three anti-virus companies in this way in blocking malicious links and malicious websites in the news feeds and messages from the 1.35 billion Facebook users. Users often miss the most basic security to prevent infection and remove, observes the engineer on.
