Analysts expect tech's major players, including IBM ( IBM), H-P ( HPQ) and EMC ( EMC) to continue with the buying spree they started last year. What they're looking for in 2010: security firms, a sector led by the likes of McAfee ( MFE). "To all the stacked dominators -- the large guys like Oracle ( ORCL), Microsoft ( MSFT) and Cisco ( CSCO) -- security, which is very relevant to their software and network infrastructure offerings, is a top priority," says Don More, a partner with New York investment bank Updata Advisors. "More and more of them are realizing that security and system maintenance should be in the same box." More points specificially to H-P, which he says "lacks the core capability" of security expertise that would benefit the firm on its software side. In terms of targets, McAfee has long been rumored a good buy for large tech firms, despite its $6.24 billion market cap that makes it an expensive grab. McAfee reported better-than-expected results for the fourth quarter, reporting revenue of $525.7 million, up from $424 million in the same period last year and well above analysts' forecast of $514.81 million. Also a potential target is ArcSight, IT security's rising star, which sells devices for monitoring security threats across data centers.
