Do not open unknown attachments. 3. Emails can be tapped. 4. Have backups for important emails. 5. Always log out.

Computer & Network Safety  Anti-virus Software – detects and removes or quarantines computer viruses.  Firewall – hardware and/or software that protects a computer or network by monitoring all outgoing and incoming traffic.  OS and software should always be updated.  Only trusted open-source applications should be used. Examples of antivirus and firewalls: Lecture 3 4 C. Safe Browsing Lecture 3 5 D. Password Protection  Should be strong and changed periodically.  Should contain uppercase, lowercase, numbers and special characters if possible.  Never use same passwords in all accounts and never share your password.  Use two-factor authentication which is a method that requires two ways to verify your credentials. For example, bank applications require both password and a sent code. Lecture 3 6 D. Password Protection (cont.) The table below shows a comparison of the time taken to crack a password using skiddy (a very easy and simple cracking code) passwords of only lower cases and passwords of all characters between short and long password. All Characters Only Lowercase Password Length minute 1.36 Seconds 046. Characters 4 centuries 2.10 days 2.42 Characters 8 millennia 20 months 2.07 Characters 9 Lecture 3 7 D. Password Protection (cont.) Which one of these passwords do you think is easier to crack? C0mpl3x! ThisIsMyPasswrd Lecture 3 8 E. Privacy Policies & Agreements Companies need information about their employees or clients and users to run their business effectively.  Consumers want businesses to:  Know who they are, but not to know too much.  Provide what they want, but not gather information on them.  Read the privacy agreement policy and make sure to understand it.

Backup tools: - USBs and CDs - Hard Disk - Cloud Lecture 3 11 H. Other Security Measures  Anti-rootkit Software – stops outsiders taking control of your machine.  Encryption – scrambles the contents of a file so that you can’t read it without the decryption key.  Biometrics – the use of physiological characteristics for identification purposes, such as Fingerprint and Iris (eye) scanners. Lecture 3 12 Top Internet Security Tips 1. Never include personal information in an email message when you don’t know the recipient. 2.
