Human Factor in Data Breaches in Financial Sector

There is a rapid increase in the usage of digital channels in the financial sector such as internet banking, digital wallets, mobile banking. This increase the exposure and thereby cyber-attacks causing financial and reputation losses to institutions.

Financial sector faces three times cyber-attacks compared to other sectors as per various published reports. With increasing risk of cyber threats, this sector is facing huge challenge of data breaches and therefore there is extreme need of strengthening their cyber security postures.

Data breaches (card data, Personal Identifiable Information etc.) causes exponential rise in the cost and stringent data privacy acts & loss of customers increases the impact further.

A data breach happens not only when data is lost or illegitimately accessed but also when itโ€™s confidentiality/privacy or integrity is compromised.

Data loses its confidentiality when an unauthorized person view, alter or steal the information of customer. The integrity of the system is affected when data in the system is changed irresponsibly or with malicious intention.

Below are some examples that fall in data breach (confidentiality or integrity compromise) by the employees within institutions:

  • Selling personal information of customers to marketers and third parties for monetary gain
  • Mr. Xโ€™s relative in a bank views and provides banking details of Mr. Y to Mr. X thereby breaching confidentiality of Mr. Y data
  • Mr. Xโ€™s residential address is not updated by an irresponsible employee and his account statement is sent on old address which is read by Mr. Y staying at that address thereby breaching confidentiality of data
  • Exchanging a sum of money from another customer account to own account by altering data in the system

All above data breaches can be done by an employee with malicious intention or an employeeโ€™s negligence toward security giving opportunity to another insider or outsider to perform these acts.

Educate employees at all levels about cyber threats: cyber crime is not just the domain of the IT/ network security function. There are different types of cyber crime, from hacktivism to data theft, which affect different functions of the financial institution in varying ways. Contact for any query.
