Ans: (a) Use passwords to login to your computer: Use passwords that are difficult to guess. Passwords are difficult to hack if they are a mix of small (For example ‘a b c d’) and capital letters (For example, ‘H J E R’), numbers (For example ‘8 7 6 5’) and special characters (For example, ’% ^ # $’). This would prevent unauthorised people from using your computer.

(c) Encrypt Data: This is usually done by banks and companies in which important customer information is stored. They can encrypt their entire hard disk using encrypting feature in Windows (Bitlocker). This would force users to use a decryption password (or key) before starting the computer thus preventing unauthorised usage.
(d) Secure sites: Give details of your credit card or bank account only on secure sites. See in the address bar of the browser. If the site address starts with https:// and a lock symbol, then it is safe to give your credit card and bank details.
