How Can Financial Institutions Prevent Breaches with Layered Security?

According to CSIS, financial institutions are the top targets of cybercriminals.

For many, this is not surprising. It’s not difficult to see what makes banks appealing to cybercriminals.

Besides direct monetary gain, threat actors can obtain the sensitive information of millions of people who trust their bank with their personal data.

Banks are already investing a lot in cybersecurity — especially as they add more convenient services such as mobile applications and online banking for their users.

So why are successful breaches of financial institutions still headlining in the news?

For starters, let’s take a look at the latest cybersecurity breaches to get a sense of how cybercriminals exploit weaknesses to breach financial institutions.

Recent Banking Breaches

What can we learn from the latest hacking of financial institutions? When we compare recent cyber incidents in the financial sector, clear patterns emerge:

● A successful cyberattack can set financial institutions back millions

● Hackers use versatile methods to obtain sensitive data or financially damage institutions

● Even major banks that already allocate a lot of resources towards cybersecurity can be breached

● Financial damage is not necessarily the hacker’s endgame

In April 2022, the platform Beanstalk Farms reported a loss of $180 million in Bean cryptocurrency. Hackers exploited voting rights to obtain the currency and caused a decrease in the value of the Bean.

In the last couple of months, researchers have uncovered different malware that has been used to target financial institutions.

For example, in South Korea, they spotted Fakecalls. This trojan called victims and impersonated banking officials, urging them to disclose banking information and make transfers.

Some of the major financial institutions that have recently fallen victim to cyberattacks include Block and Flagstar Bank.

Block compromised the information of as many as 8.2 million users and employees when a former employee improperly downloaded Cash App Investing reports containing customer data.

Flagstar Bank’s perpetrators leaked the social security numbers of 1.5 million users after a data breach.

Layered Security to Protect Finances

What kind of cybersecurity do financial institutions need to deploy on their premises to avoid such attacks?

Comprehensive and layered cybersecurity. This means having different tools, protocols, and systems that cover any possible weak spot within the infrastructure itself. Cybersecurity mesh can improve collaboration between various security solutions.

Instead of working in silos, the model integrates the architecture into a more flexible and collaborative one. Companies that adopt this approach can add more security tools as they grow, as well as adjust security functions based on their needs.

What’s more, to continually monitor movement within the infrastructure, CSMA utilizes the power of artificial intelligence. This delegates repetitive tasks to IA and frees up time for cyber analysts, enabling them to allocate more resources toward mitigating advanced threats.

Final Word

Financial institutions already invest a lot in their security because there’s a lot at stake.

Losses following an attack include people whose sensitive information has been stolen, different currencies (e.g., crypto), leaked portfolios, and lost life savings.

Recurring attacks can, and often do, lead to a lack of trust and therefore, loss of clients.

To protect users' personal information — which in the case of financial institutions can lead to data leaks and further attacks on different infrastructures — it’s necessary to deploy strong and layered security.

Recent major attacks on financial institutions have shown that institutions have to guard their assets against different types of attacks — even from those they can’t yet expect.

Cybersecurity Mesh Architecture encourages working smart instead of hard by uniting the tools a business would use in a single infrastructure.
