What is the meaning of this Access/Admission Control & ID Management Access or Admission control determines the authorised participation rights of a resource, a user or a service within a distributed system. This can include the sourcing of data, and the access rights to read/write and usage of data over the lifetime of a service. The potential threats and consequent attacks include masquerading or spoofing of identity to gain access rights to the data. It can also involve Denial of Service (DoS) attacks that detrimentally limit access (e.g., depletion of computing resources and communication channels) leading to the consequent inaccessibility and unavailability of the distributed resources/services. A distributed system entity (resource, service, user or data element) participates (via access control) in a distributed system with a physical or logical identity. The identity, statically or dynamically allocated, can be a resource identifier such as an ID name or a number1 . It…
In today's society, what is the relevance of access restrictions? In your answer, please include at least two examples of access limitations.
1. Let us consider an application where we need to run a secure Information Management System. We are to receive very confidential information from our customers and keep them save in our system. These information are sent to us in the softcopy forms. We are to protect our customers’ confidentiality even from ourselves, we are not to see the information they bring to us, or else the confidentiality is compromised. Your job as computer security officer is to verify the authenticity of the important document received in order to save them under the appropriate users. Mind you; you have no access to the users’ usernames and passwords, you can store but cannot retrieve except the user himself. Secondly, you are to protect the passwords and usernames to make impossible for everyone (including the system administrators) except the users themselves to access even if the whole database is hacked or stolen. i. Based on your knowledge in computer security, which cryptographic mechanisms would…
