7. Restricting access – Single-factor authentication
Single-factor authentication (SFA) is where the user can obtain access to an account or service using one factor such as a username and password.
Risky if same password used for many applications
Recommend using unique password for each application

8. Restricting access – Two-factor authentication
Two-factor authentication is a security method by which users obtain access by providing two separate factors to identify themselves.
Three different types of factors that can be used for authentication are:
Knowledge factor – knowing a password / PIN number
Possession factor – owning a membership card / mobile
Biometric factor – human characteristic fingerprint/DNA

9. Restricting access – Two-factor authentication
Mobile transaction numbers (mTANs) example
Member needs:
Password (knowledge)
Mobile phone (possession)
This simple method of two-factor authentication would be suitable for Fun Gym, as members only need knowledge of their password and possession of one of the following:
Their laptop/tablet computer and their mobile phone
Their smartphone for direct login
Member enters username and password into Fun Gym login page
Fun Gym receives login request from member and texts security code to member’s mobile phone
Member then enters the security code to log in to the website

10. Further Security Password advice
Use strong passwords with a mixture of numbers, letters, symbols and lower/upper case
Change passwords regularly
Access rights – set up by system administrator to limit network access to relevant files only for a user
Encryption – used to make stored data more secure, by making it unreadable to people who do not have the key to decode it

11. Validation & verification
Validation – It is important that when members are logging on to the Fun Gym website, validation checks are in place so members can log in correctly
Verification – This involved ensuring that the data that is entered is verified and correct

12. Validation checks
Type Check – checks something of the correct type is entered. E.g. a date in a date field, a number in a number field etc.
Range Check – checks something is within a specific range. E.g. an order quantity is between 1 and 10, > 18years old, or <21 etc.
Presence Check – checks that something is there. E.g. Mandatory field. Makes sure REQUIRED fields are entered.
Format Check – checks what is entered is of the correct structure. E.g. Postcode (LLNN NLL) E.g. TS23 3DX. E.g. a phone number is STD: NNNNN Num: NNNNNN
Length Check – Ensures that information is of a specified length. For example a name field may be more than 2 characters. If it is less it would not be accepted.
