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 manger for Windows NT, and at one time he oversaw the Microsoft.com Web site. He is expected to return to a new position at Microsoft some time later this year, the spokeswoman said.
