existingPROBLEMS DE-CENTRALIZED

each of the dealer’s inventory information is contained within their own location and is not centrally located for distribution

using an Excel spreadsheet at each dealership INACCESSIBLE 

if one person has the spreadsheet open and is entering data, others can’t get access to it people will save personal copies of the spreadsheet for their own use

STATIC go and actually find the car to double check spending too much time and money making phone calls and faxing inventory sheets between

dealerships Not all of the salespeople update the spreadsheets at each location in a timely manner update the main spreadsheet at the end of each month

INSECURE every employee should not be able to access certain information

SUSCEPTIBLE TO INPUT ERRORS forgetting to go back and enter data into it or entering incorrectly = inaccurate data

COMPLICATED dealership doesn’t really have anyone who specializes in the spreadsheets who can show us

how to efficiently work with them

• YOUR NEEDSo Each employee of NOMO Auto Group

needs access to different parts of the database.

o Data needs to be protected from employees who do not need to access it.

o Data needs to be protected from outsiders trying to attack the system and alter data.

• Secrecy, Integrity, Availability…

• Secrecy, Integrity and Availability can all be achieved by creating a individual account system and using Discretionary Access Control to determine who has access to what data.o Each employee is assigned a user account name and

password.o To access the database they will need to enter their

user-name and password.o Permissions assigned to each user groupo DBA assigns and updates permissions exclusively

ADDITIONAL PROTECTION • When employee is signed into data base,

password re-entry will be required to view restricted data.

• After five minutes of inactivity, the system will log the user out automatically.o Both are controls to prevent unauthorized

access in the case of a user forgetting to log out after use.

• If a user forgets their password they must request a new one by answering their secret question o Passwords are encrypted and stored in the

database.
