After four years at the helm of Microsoft’s security group, Mike Nash is taking a break. This June he will go on sabbatical after handing over responsibilities to his replacement, Ben Fathi.Nash led Microsoft’s Security Technology Unit during a period in which the security of Microsoft’s products was increasingly scrutinized following a number of worldwide worm attacks, including Slammer and MyDoom.The 15-year Microsoft veteran was responsible for directing Microsoft’s response to these threats as well as for setting its overall security strategy as the software vendor struggled against a public perception that its products were insecure.Nash’s departure was announced Thursday as part of a sweeping reorganization of the company’s Platforms & Services Division. Fathi comes from Microsoft’s storage division, where he managed the company’s Windows file server, NAS (network-attached storage) and branch office businesses. As Nash’s replacement, he will report to Brian Valentine, head of Microsoft’s Core Operating System Division.A Microsoft employee since 1991, Nash was the first product manager for Windows NT, and at one time he oversaw the Microsoft.com website. He is expected to return to a new position at Microsoft sometime later this year, a spokeswoman said. -Robert McMillan, IDG News ServiceFor related news, read Microsoft Restructures Windows Unit and Report: Sinofsky to Take Over Windows Team.Keep checking in at our CSO Security Feed page for updated news coverage.
