6. Your Bank Account / Financial Detail is a Major Target

An antivirus may protect you from viruses but it will not protect you from yourself. Identity theft and scams are a great industry today and one primary information sort after by internet fraudsters is bank account/financial details.

Here are some common sense tips to help you improve your security on the internet:

7. Don’t Follow Links in an email soliciting personal/private information

Occasionally you will receive an email, informing you of a problem with your bank account, ATM card, Debit card, Credit card, email account, social network sites, Binance account, PayPal account, and instructing you to visit a website to update your account details. Sometimes you will be told you have won a lottery or a promo, and you will be told to enter private information to redeem your winnings.

It is a good idea to ignore such emails as they are most likely to be internet scams. These types of security threats are called phishing threats and will usually urge you to fill a form which will include fields for entering your financial details, PINs, or passwords. Falling for such an internet scam is one of the biggest mistakes you will make on the internet.

One way to identify internet scam mails is that they will give the impression that it is urgent and you stand to lose a lot if you do not act immediately. As a rule never enter confidential information on any site you are not familiar with.

8. Don’t Download from a site you do not trust

Do not download anything you see on the internet. Some sites embed malware in downloads. There could be a malware or spyware embedded in a screen-saver, porn photo/video, or free software, so be careful when downloading on the internet. A good internet security tip is to download only from trusted sites.

9. Don’t shop at online sites you are not familiar with

Just like when downloading, be careful where you do your shopping on the internet. Some online shopping sites are only interested in collecting your credit/debit card details. Some will offer unbelievable prices just to persuade you to enter your financial details. Shop only at trusted sites. Be careful when shopping on the internet.

Do not reveal your credit/debit card PIN to anybody, not even bank officials.

Identity fraud is a major security risk on the internet today and only you can save yourself from such security threats.

10. Do not use your Email Credentials for Opening other Accounts

One common mistake people make is to use their email credentials for opening other account. For example, when opening a Facebook account some users will use their email and the same password they use for accessing their email as their Facebook password. They do the same even for less trustworthy sites.

The implication of this security breach is that if your Facebook account is compromised, your email will also be affected. So make sure the password to your email is unique and not used with other internet services.

11. Have one email for serious communication

Since most internet services now demand for your email when registering for services online, it is a good idea to reserve one email for serious business and professional communication and open others for fun and leisure. Use the professional email for serious business. Opening multiple emails is not a problem as you can do that free.

12. Do not share too much on social media services

To some people social media has given us the opportunity to become stars. However, you should be careful what you share on social media sites. Do not just accept anyone as a friend just because they request, remember what friends truly mean and keep it at the back of your mind when choosing your friend. Update your privacy settings and make sure you are not sharing too much on Twitter, Facebook, LinkedIn, etc.

13. Your passwords and PINs are major targets

Passwords and PINs are the hottest information sort by fraudsters, protect your password and do not reveal it to anyone. Change your PIN and password using authorised channels. Never change your PIN via an email message. Revealing your email to anyone will compromise your security on the internet.

You should also change your passwords and PINs regularly. Every six months is recommended.

Your internet security depends on the software protection you give your PC and your internet browsing habits. Do well in both and your internet security will be assured.

Some internet security threats for your PC are:

Malware: Causes malicious damage on your computer or data stored in it. For example a malware can delete important files on your PC without your consent. A good antivirus will shield you from security threats posed by malware.

Spyware: Steals confidential information from your computer. A good antivirus will shield you from security threats posed by spyware.

Keyloggers: capture, record and transmit via the internet to criminals your keystrokes. This can then be used to obtain passwords, financial information and more.

Screen grabbers: capture, record and transmit via the internet to criminals your clicks.

Zero day attack: an attack that takes advantage of a security hole on your internet browser for which a solution have not yet been found.
