Unit 12 – IT Technical Support – Anne Sewell Aims of the lesson: To carry out a back-up of files to a USB or desktop. This is a build-up exercise towards M4 (Task 4), Assignment 4 – Advice and Guidance

For your assessment criteria you will need to do the following: “For M4, you should produce a ‘User’s Guide’ to solving common faults. The idea of this it will save you time having to respond to the same problem repeatedly. As a technician you would send a help or ‘crib’ sheet to a user to help them solve their problem (how to reset a password for example – does it need a capital letter or a combination of upper and lower case? Does it need a number?) Choose two faults and include appropriate screenshots and pictures. The material should be different from that provided for P5 but any style or format you wish to use is acceptable.  user guides Task 4 – Additional support M4 provide additional support material to users

Why back-up files? To provide “Data security”? Or the  Physical security, network security and security of computer systems What does “integrity” mean?  “the state of being whole, entire, or undiminished” – in other words your files are intact!

Data security is about keeping data safe. Many individuals, small businesses and major companies rely heavily on their computer systems. If the data on these computer systems is damaged, lost, or stolen, it can lead to disaster. Data Security

Key threats to data security Data may get:  lost or damaged during a system crash - especially one affecting the hard disk  corrupted as a result of faulty disks, disk drives, or power failures  lost by accidentally deleting or overwriting files  lost or become corrupted by computer viruses  hacked into by unauthorised users and deleted or altered  destroyed by natural disasters, acts of terrorism, or war deleted or altered by employees wishing to make money or take revenge on their employer Data Security

Measures that can be taken to keep data secure include:  making regular backups of files (backup copies should be stored in fireproof safes or in another building)  Using Cloud storage facilities  protecting yourself against viruses by running anti- virus software  using a system of passwords so that access to data is restricted  safe storage of important files stored on removable disks, eg locked away in a fireproof and waterproof safe  allowing only authorised staff into certain computer areas, eg by controlling entry to these areas by means of ID cards or magnetic swipe cards Keeping Data Secure

 always logging off or turning terminals off and if possible locking them  avoiding accidental deletion of files by write-protecting files/USB (flash sticks)/disks etc  using data encryption techniques to code data so that it makes no apparent sense! Keeping Data Secure

Online Banking When you bank online, look out for the http in the address bar has changed to https. This indicates that a secure connection between your computer/the bank's computer has been established. Data sent between the two computers is encrypted - anyone trying to intercept your data will receive meaningless data instead. The encrypted data can only be decrypted into readable data by using a key that is known only to the two computers - yours and the bank's. This is an example of a card reader: Other ways of keeping Data Secure

A padlock also ensures security:

Question  In a local doctor's surgery, data about the patients is stored in a database on a computer.  Can you name 2 physical precautions that should be taken to keep the data secure. Data Security

“Since USB flash drives are often used to store media files, which can be large, the smallest one should buy these days is 2GB. With technology improving rapidly, USB flash drive capacity is constantly increasing.” What Size USB Flash Drive Should You Buy? | eBay Should-You.../g.html The numbers game:

Answer  keep the computer area secure  keep backups in a safe place Hint: The key word is physical - the question is asking for the physical precautions you can take to protect data. Keeping the computer area secure and keeping backups in a safe place are both physical precautions. Swipe card entry, locking terminals or controlling access to computer areas would also have been good answers. Data Security

Question  The doctor needs to see all the information about patients. The receptionist only needs to see some of the information.  Describe one way in which software could restrict access to patient information. Data Security

Answer  Make it so users must enter a password to gain access to certain areas of the database. Hint: The question is looking for detail about different types of access for different users. This answer clearly highlights the need for having passwords for different levels of access. Data Security

Aims of the lesson:  You will need to provide evidence of this task by using annotated “before” and “after” screen dumps of backing up and restoring data. A screen print of backing up data from one drive to an external (USB) drive is acceptable.  In addition you will need to print off the results of your BBC questionnaire. Data Security
