24. Server Security Issues

Data flow control

What manages the transfer of information to and from your servers?

Aggregation

There are two specific types of attack that database administrators should pay careful attention to. This attack occurs when an individual with a low level security clearance is able to put together facts available at that low level to determine a very sensitive piece of information that they should not have access to.

Inference

There are two specific types of attack that database administrators should pay careful attention to. This attack occurs when an individual can figure out sensitive information from the facts available to them

NoSQL databases

What type of database implements an extremely simple format known as a key-value store. These databases don't have the defined record formats of SQL databases. They're basically a giant filing cabinet that stores values using a key. Values can later be retrieved from the database by referencing that key. These databases are very popular for web applications because of the speed. 

key

 NoSQL databases only have two elements. What element is used to identify and locate data in the database?

value

 NoSQL databases only have two elements. What element is associated with the key?

client-server model

What model is a central computer, known as a server, is responsible for accepting requests from other computers, known as clients, for accepting requests from other computers, known as clients. After receiving a request, the server may retrieve information, perform a calculation, or undertake some other action on behalf of the client before providing the client with a response. 

grid computing

What kind of computing builds a virtual supercomputer by assembling the unused resources of hundreds, or thousands of individual computers at different locations, and using them to work on the same problem?

peer-to-peer computing

What kind of computing is another example of distributed computing where many different computers band together to provide a service to each other, and or the general public. Unlike grid computing, these networks often have no centralized controller
