Solution
Shared resources, also known as network resources, refer to computer data, information, or
hardware devices that can be easily accessed from a remote computer through a local area
network (LAN) or enterprise intranet. Successful shared resource access allows users to operate
as if the shared resource were on their own computer. The most frequently used shared network
environment objects are files, data, multimedia and hardware resources like printers, fax
machines and scanners.
Operating systems have to balance the conflicting goals of convenient resource sharing and
protection against unauthorized resource access. Windows offers a variety of mechanisms such
as user and group permissions, shares, and access control lists with inheritance. On the other
hand, Linux has a much simpler implementation of users and groups.
Following methods are adopted to achieve resoure security: 1) using global user identifiers to
replace traditional user identifiers; 2) implanting global user identifiers into kernel entities such
as processes and files; 3) adopting an access control mechanism based on global user identifiers.
The most important feature of our approach is that we implement it by introducing innovative

2. Problems addressed by modern file systems:
Issues to consider:
Contiguous allocation (also called "extent-based"): allocate files like segmented memory
(contiguous run of sectors). Keep a free list of unused areas of the disk. When creating a file,
make the user specify its length, allocate all the space at once. Descriptor contains location and
size. Example: IBM OS/360.
