Internet Security - Banking

Internet Security - Banking

In this chapter, we will deal with banking security issues related to e-banking or the so called Internet banking, and credit or debit cards based security issues.
E-banking is an electronic payment gateway which enables all the customers of a bank to do banking transactions through their computers without the need to go physically to the bank.
Normally to create an e-banking account the client has to go physically to the bank to be able to open it and authenticate it when it opens. A customer can link this account with their loans, current account and many other bank products.

How to do an e-Banking Transaction Safely?

Always enter the e-banking link by typing it yourself and not through an arriving email it can be a phishing mail. Always connect through a secure connection to the website and check if the webpage is authenticated like in the following image, where the connection is a secure Https − and the authenticity of web I have checked it through the green bar which is a certificate which means that this web is pre-authenticated.
E-Banking
Be cautious of any unexpected or suspicious looking pop-ups that appear during your online banking session. Think about the process you normally go through to make a payment to someone – be suspicious if it differs from the last time you used it.
Never give anyone your login details in full either by email or over the phone – your bank will never request these in this way. Check your bank statements regularly and contact your bank immediately if you find any transactions that you did not authorize.
When you send money via your online bank account, always double check the amount you are sending as well as the account number and sort code you are sending it to.

Credit Cards

Generally, these cards are issues by card providers like banks and they are connected with the client’s bank accounts and help to make payments and as this too is being used more often increasing the possibilities of frauds.
Credit Card
Credit card fraud is a theft carried out by using a credit card or any alike payment mechanism as a fake source for fraud transaction. A common type of fraud happens when an offender purchases an item online, by utilizing a credit card number that they have obtained in unethical ways.
