Data Security for the new system

Extracts from this document...

Introduction

Objectives of the new system Below are the objectives that must be achieved when my system is complete. These will help achieve the goals I have for my system. * The new system has to be efficient and fast. It has to hold data about the schools, the amount of uniform stock has left to the relevant schools, keep track of stock levels and make sure the correct amount of stock leaves the warehouses. The system must be easily accessible, be presented clearly and make sure its readable. The data required by the user must appear quickly as data may be required while a user is speaking to a client. * The main objective that the system must achieve is to create a suitable database that will hold information on the schools, stock levels, and the stock control that are held within the warehouse. It has to say where the stock has gone and keep tabs on how many stock schools have taken for the year. * The system will hold details of the schools who have been dealing with them. Every school will have a unique user ID number. If the user requires information about the school they can do a sort to find the school using this number. ...read more.

Access rights to a particular set of data could typically be set to Read-Only, Read/Write, or No Access. This ensures that users within a company can only gain access to data that they are permitted to see, and can only change data on the database if they are authorised to. Securing against fraudulent use or malicious damage Disgruntled employees or theft of software or data that may fall into the hands of competitors often exposes organisations to the possibility of fraud, deliberate corruption of data. Measures to counteract these risks include: * Careful vetting of prospective employees * Immediate removal of employees who have been sacked or who hand in their resignation, and cancellation of all passwords and authorisations * Separation of duties * Prevention of unauthorised access by employees and others to secure areas such as computer operations rooms, by means of machine readable cards or badges or other type of locks * The use of passwords to gain access to the computer system from terminals Protection against viruses Below are steps that can be taken to minimise the risk of suffering damage from viruses: * Making sure that all purchased software comes in sealed packaging * Not permitting floppy disks containing software or data to be removed from or brought into the office * Using anti virus software to check all floppy disks before use Periodic backups This is the most common technique to ensure that data isn't lost. ...read more.

Conclusion

Smaller amounts of data may be able to fit onto zip drives. * Location of backup storage. The data needs to be held in a secure location incase of fire ore burglary. Many organisations have fireproof safes for latest backups, with other sets of backups stored off-site * Responsibility for implementing the backup strategy. Although a computer operator may perform the regular backup routine, the senior manager should have overall responsibility for ensuring that all aspects of the backup strategy are properly implemented. * Testing of recovery procedures. At regular intervals the effectiveness of the backup strategy needs to be tested to ensure that the organisation can recover quickly from loss of data. It would be bad to see that the tapes or disks meant for backup ended up to be blank Recovery procedures A contingency plan needs to be developed to allow rapid recovery from major disruptions. In addition to file back-up procedures it is necessary to: * Identify alternative compatible equipment and security facilities, or implement a service agreement that provides replacement equipment when needed. This may also include putting up temporary office space * Have provision for alternative communication links As you can see from all the procedures above doing these measures will take time. The company is also quite weak with computers so training them on how to get the best from their security will have to come from an external source. ...read more.
