Although many books deal with the generalities of computer security, there is a need for texts looking in-depth at specific areas. This book discusses one such area: the access control mechanisms available in mainframe and mid-range computer systems. This subject is of particular relevance to information systems auditors analyzing security mechanisms in various computing environments, who need a general and logical applicable method. Having explained the general information security framework and access control within this context, the book covers the practical application of this concept for particular computer systems (IBM mainframe and mid-range, DEC's VAX/VMS, Tandem's Guardian and Siemens Nixdorf's BS2000).
