An employee who needs
permission to access an electronic workspace, database, or other
information system resource typically fills in a request form and
obtains approval from the responsible manager. The manager then
routes the request to one of the system’s administrators.
Highly trusted and well-trained systems administrators spend a
significant amount of time doing nothing more technical than adding
or removing names from access control lists. In large
organizations, it’s not unusual for systems administrators to have
never met any of the people involved in a specific request. The
administrators may not even work in the same office.
Hackers have learned to take advantage of this approach to access
authorization. They begin by probing an organization. The hacker
doesn’t expect to compromise the system during this initial probe.
He or she just starts by making a few phone calls to learn who is
responsible for granting access and how to apply. A little more
probing helps the hacker learn who’s who within the organization’s
structure. Some organizations even post this information online in
the front of employee directories. With this information in hand,
the hacker knows whom to talk to, what to ask for, and what names
to use to sound convincing. The hacker is now ready to try to
impersonate an employee and trick a system administrator into
revealing a password and unwittingly unauthorized access.
Organizations determine who needs access to which applications.
They also need a system through which they can authenticate the
identity of an individual making a request. Finally they need to
manage this process both effectively and inexpensively. Prepare a
response to the below using the MS Word application:
