Understanding various current threats and can help you to avoid to becoming a victim of Phishing, Pharming, Fraud Emails, Viruses/Trojans, ATM Type Fraud..etc.

Those are some good points for education:
- Use a unique password or PIN and change it regularly. You should never disclose your password or PIN to anyone
- Be very suspicious of any e-mail or phone call received from a business or person that asks for your password, passport number, account or credit card information unless you have initiated the transaction.  
- Maintain different passwords for multiple services
- Always use anti-virus software. Keep anti-virus software up-to-date.
- Ensure that your browser and operating system are up to date and security patches application

This sounds like a homework question.
That's because humans are the weakest link in the security chain. To reduce risks on different fields:

- Educating the user on how to use/keep passwords. Complexity/length. Repetition on other platforms (don't use same password on other systems) etc etc.
- Educating the user on surfing behaviour (clicking on popups that look like an antivirus screen) etc
- Educating the user on emailing behaviour (think before clicking on links or attachments, even from strangers, and emails in foreign languages).

When education is proper, the reliance on expensive software (while still needed, it means the hard to catch 0-days and drive by exploits are less of a concern, as the speed of the updates of any security package lags a bit when a new widespread exploit is in the wild, while it's still being analysed by the companies)
Can you describe the business problem and business environment around this question? Or if it's an academic question, please identify it as such. The two types of questions require different responses from any participating experts.
