Since its launch at the Infosecurity exhibition and conference in April, the UK branch of the US-based Information Systems Security Association (ISSA) has boosted membership fivefold, from about 20 founder members to more than 120 organisations and individuals.
Well over half of its members are from the corporate IT user community.
ISSA, which is a global organisation aimed at identifying and promoting best practice IT security management approaches, works at several levels - from local technical, business and management perspectives to helping create national security policies and frameworks.
The first major quarterly meeting, on 7 October, will focus on two areas: the BS7799 security standard; and on optimum response to security incidents.
Microsoft's head of security Stuart Okin will step into the lion's den at the meeting to discuss the direction his company is taking on security.
Louis Gamon, of Yell, and the association's regional director for Europe and Africa, said the organisation is on track for achieving 250-300 members by the end of 2004.
"At present we are having meetings in the London area but will aim to set up regional chapters as members from elsewhere in the UK join," he said.
The subscription is $95.
Gamon aims to involve not only his own members but all 600 or so certified information systems security professionals in the UK in a series of seminars with various suppliers.
