International Business Machines Corp. (NYSE: IBM), the world’s largest seller of computer services, has acquired security firm Trusteer with the goal of setting up a security lab focused on counter-fraud and malware detection.

Financial terms of the transaction were not disclosed.

Trusteer, which has offices in Boston and Tel Aviv, Israel, and is backed by U.S. Venture Partners, specializes in protecting web applications, computer networks and mobile devices from cybercriminals.

The deal is expected to expand IBM's current portfolio with stronger threat intelligence services.

Trusteer's services are delivered through cloud technology, an area IBM has been recently developing, especially through various acquisitions. In June, it acquired SoftLayer for roughly $2 billion. 

Separately, IBM announced plans to create a security team made up of Trusteer and IBM employees. The lab, to be based in Tel Aviv, will include researchers and developers and focus on creating services geared toward cyber security and the prevention of financial crimes.

The deal is expected to close in the third quarter of 2013.
