Access controls

. Access controls are security features that are usually considered the first
line of defense in asset protection. They are used to dictate how subjects
access objects, and their main goal is to protect the objects from
unauthorized access. Access control models are frameworks that use access
controls to enforce the rules and objectives of the model. In your essay
response, compare the different Access Control Models and give an
example of one that you have used in a work situation or if that is not
possible, one that you’ve read about in a scholarly article.

  1. Relying on a password to secure access to a system does not provide
    enough security in today’s complex world. The Office of Personnel
    Management learned this the hard way in 2015. Since OPM was hacked
    and it was learned that the attackers compromised their system
    administrator accounts that were protected only with passwords, the
    Federal government has required the use of multifactor authentication for
    privileged accounts. Describe the three factors that can be used in
    authentication and give at least two examples for each.
  2. There are two main methods of access control administration that an
    organization can choose between to achieve the level of protection that
    they need to secure their assets and information: centralized and
    decentralized. Describe the RADIUS, TACACS, and DIAMETER forms of
    centralized access control administration. What are the advantages and
    disadvantages of decentralized administration.
