Phil Evans: User advocate.
Evans, a president and longtime board member of the International Communications Association, helped shape the telecom industry in the post divestiture era. Widely respected as a network visionary, Evans influenced a generation of telecom and data communications managers in spearheading the ICA's educational efforts in an age of telecom services such as ISDN and frame relay. Evans crafted telecom strategies at a variety of Fortune 500 companies, including Ashland Oil, Dresser Industries, FMC and Occidental Petroleum. He also co-wrote The Network Manager's Handbook.
Harold Greene: Dictated change.
With his infamous 1984 Modified Final Judgment, this federal judge broke up the Bell System and forever changed the telecom industry. He expected competitive local and long-distance service to blossom if AT&T were a long-distance carrier and local services were left to seven regional holding companies. In reality, his decision led to regulatory and legislative wrangling that continues today. One has to wonder what Greene, who died in 2000, would make of today's market in general and the new AT&T in particular.
Ed Whitacre: Telecom's biggest gun.
Last year Whitacre brought the Bell System breakup full circle when he led SBC's acquisition of AT&T. The move was only natural for the tough-minded, savvy executive who has been reshaping telecom boundaries for years by acquiring fellow regional Bells Pacific Telesis and Ameritech. Now he's at it again, with AT&T's proposed acquisition of BellSouth.
Shlomo Kramer: Firewall evangelist.
Wherever there's an enterprise network, firewalls stand guard at its entry points. Some may argue that a garden-variety firewall no longer provides enough enterprise protection, but no one can deny how significant the technology has been for corporate security during the last decade. Kramer and his compadres at Check Point, including CEO Gil Schwed, for spurring widespread firewall use within the enterprise, while and Bell researchers Bill Cheswick and Steve Bellovin get the nod for educating the masses in their widely read Firewalls and Internet Security: Repelling the Wily Hacker.
Taher Elgamal: Encryption go-to guy.
The world of data is a more secure place thanks to Elgamal. While chief scientist at Netscape in the late '90s, this encryption guru pioneered the SSL protocol that is a primary security mechanism for extended enterprises and the Web. Before that, he oversaw the engineering team at RSA Security that developed the industry-standard RSA cryptographic tool kits.
