Now that increasing numbers of SMEs are becoming Web-enabled, the AEB said it is vital that smaller companies have access to information that will help them to use this technology safely.
The industry body said the guidelines, which are sponsored by the Department of Trade & Industry and law firm Masons, will enable SMEs to access easily understandable advice, written in "plain English", to help them develop and implement an information security policy for Web sites and e-business services.
The guidelines are intended to work as both a stand-alone document and a companion to BS7799, the information security management standard.
Although the guidelines are aimed at SMEs, companies of all sizes cannot ignore the security issue, said Jon Fell, an IT lawyer at Masons.
"There can be little doubt that online security is one of the most important issues facing business today, and it will become increasingly important as more businesses and government departments move online," he said.
"The guidelines give clear, commercial and practical advice on information security to all businesses regardless of their size."
The AEB is a coalition of five trade associations: the Confederation of British Industries, the Computing Services and Software Association, the Direct Marketing Association, E-Centre and the Federation of the Electronic Industries.
