How can I be safe on the internet?
- Don’t click on pop-up messages: If you see unsolicited pop-ups, such as a message warning that a computer is infected and offering virus removal, don’t follow links or click to accept software downloads. Doing so could result in you downloading malicious software.
- Don’t follow links in unexpected emails: Such links can take you to bogus websites, where any confidential you enter, such as account details and passwords, can be stolen and misused. Always enter the website address you want to visit in the address bar in your browser.
- Use different passwords for every site: A different password should be used for each site you have a user account. If a password is compromised, only one account will be affected.
- Configure your internet browser for security: You can disable Java or ActiveX applets, or ask to be warned that such is code is running.
- Consider blocking access to certain websites or types of web content: In a company environment, users may want to be prevented from accessing sites that are inappropriate for workplace use, or that may pose a security threat by using filtering software or a “hardware” appliance”.
- Reputation filtering software can be used to check the sender addresses in email against a database that shows how often mail from that address is spam, or contain viruses, worms etc. The software then assigns the email a “reputation” score that is used to decide whether to block the email or to slow doen its delivery (giving priority to email with a better reputation).
- Firewalls can be used to prevent computer from communicating with the internet via unauthorized programs.
- Routers can also be used to limit connection between the internet and specific computers.
