The modern financial sector that we know and use is constantly assaulted by cybercriminals.
Every cybersecurity breach affecting a financial institution can potentially dismantle its finances and processes. Did you know that cybercrime costs are projected to reach $10.5 trillion globally in 2025, with financial services being the most targeted sector?
Recent high-profile breaches have demonstrated several reputational and financial risks, making the protection of finance tools and having the right security strategy more of a business imperative than a desirable feature.
Understanding the Common Threats and Vulnerabilities for Finance Tools
There is a good reason behind the steep increase in cyberattacks on finance tools and platforms; after all, hackers and malicious cyberattackers have a lot to gain by exploiting their vulnerabilities.
Even the most robust finance tools today are exposed to some of these cyber threats:
- Phishing and Social Engineering
- Data Breaches
- Insider Threats
- DDoS Attacks
- Ransomware
To prevent most of these attacks, understanding how cybercriminals think can sometimes be more effective than having expensive and sophisticated security tools in place. First, exploitation of unpatched systems remains one of the most common entry points for cyberattackers.
Over 94% of attacks in the finance sector are conducted through XSS, LFI, OGNL Java, and SQL injection vulnerabilities. Some of the most common vulnerabilities in finance tools and platforms include weak authentication measures, insecure APIs and web apps, third-party integrations, and misconfigured cloud services.
Generative AI is now used in numerous ways to launch AI-driven cyberattacks, including creating convincing phishing messages, complicating detection, and leveraging deepfakes. Attackers are also most likely to use malware, brute force, and phishing to steal login details and access sensitive financial tools.
While OT security measures can help you deal with security issues in the manufacturing sector, you need more sophisticated tools and mechanisms in the financial sector.
7 Proactive Strategies and Measures to Protect Finance Tools Against Cyber Attacks
Now that we understand the different kinds of cyber threats and vulnerabilities your finance tools, such as EMI and SBA loan calculators, might face, let us look at some of the measures or strategies you can implement to combat them:
#1 Ensure Regular Patching and Vulnerability Management
Businesses can often make their data vulnerable by failing to apply available security patches promptly, which can then be exploited to infiltrate networks and cause data breaches that can prove expensive and complex for businesses.
Remember the 2017 Equifax breach that exposed the data of 147 million Americans, caused by an unpatched Apache Struts vulnerability?
To prevent this, consider implementing automated patch management tools to ensure that your system and applications are always updated. Prioritize application of critical patches for your financial tools and customer-facing parts of your platform. You must also schedule vulnerability assessments regularly to identify and remediate gaps before they become vulnerabilities.
#2 Implement MFA and Strong Access Controls
Setting strong passwords is no longer sufficient when it comes to finance tools and platforms. Consider adding another layer of security with multi-factor authentication (MFA) to eliminate the risk of unauthorized access by requiring users to provide two or more factors for verification.
You may have seen that most banks and finance apps already use MFA for online banking logins and fund transfers. Make it mandatory for all users who want to access your financial tool to go through MFA, especially when dealing with administrative accounts and high-value transactions.
Prefer app-based or hardware token MFA instead of SMS-based methods to mitigate SIM-swapping attacks. Ensure that you review and update your MFA policies regularly to prepare against evolving cyber threats.
#3 Leverage Network Segmentation and Least Privilege Principles
Network segmentation entails dividing your infrastructure into multiple isolated segments in order to reduce the risk of lateral movement by attackers. Doing so ensures that even if one of your network segments is compromised, the others remain protected.
Ideally, you must separate sensitive systems, such as customer data and payment processing, from less critical network segments like guest WiFi. Restrict access to your network segments to allow only specific job roles and personnel, and monitor the traffic between multiple segments for anomalies.
For instance, if a malware infects the customer support segment in your system, network segmentation can help contain the breach, so that it does not impact other segments related to financial transactions or development.
#4 Ensure Regular Employee Training
Since most ransomware and phishing attacks begin with social engineering, your employees should be aware of the most recent cyberattacks and security measures that threaten your financial tools or platform.
Conduct mandatory, ongoing training to help your employees identify phishing and social engineering attempts. Simulate phishing campaigns to reinforce awareness among your employees and establish clear procedures to report any suspicious activity.
#5 Deploy Advanced Security Measures
Aside from the basic and foundational security measures we have discussed so far, you can also implement certain advanced security measures. With the increased use of AI and ML in automating phishing and developing adaptive malware that evades conventional detection, attackers can launch sophisticated attacks that can only be countered with equally advanced security tools.
Here are some of the preliminary steps you should consider implementing:
1. Zero-Trust Architecture
With the increase of remote work, cloud adoption, and open banking APIs, the attack surface of your business is only expanding. A Zero Trust architecture can prevent ransomware attacks and help ensure that every user and device is authenticated and authorized before accessing sensitive parts of your systems.
You must deploy appropriate Identity and Access Management (IAM) solutions that offer continuous verification and least-privilege access for all users and applications. Moreover, you should monitor and log all network activity so you can easily audit your systems and detect anomalies.
2. Cloud Security & Hybrid Environment Protection
As most financial service companies are shifting to cloud and hybrid infrastructures, misconfigurations and insecure APIs can become prime targets for cyber attackers. You must enforce strict access controls and encryption for all your cloud data to prevent unauthorized access. You should also regularly audit your cloud configurations and partner with experienced cloud providers that offer threat detection, end-to-end encryption, and compliance tools.
#6 Carry Out Regular Backups and Incident Response Planning
A well-defined incident response plan can help you minimize the damage and downtime associated with cyberattacks. By developing and updating your incident response protocols regularly, you can minimize the damage and downtime associated with cyber threats
Conduct frequent tabletop exercises and simulations with all your stakeholders. Moreover, you should also maintain offline, immutable backups so that you can test and tweak your data without any fear of data loss. Using tested backups and a rehearsed response plan can save you millions in damages, and even help you avoid ransom payments and regulatory penalties.
#7 Double Down on API and Application Security
Open banking and digital-first services offered by most financial tools and platforms rely on APIs. Unsecured APIs can expose sensitive financial data and enable fraud, leading to large-scale data breaches and financial losses.
Conduct regular penetration testing and vulnerability assessments of all your APIs and web applications. You should also implement API gateways that provide strict authentication, rate limiting, and input validation. You can even monitor API traffic to identify and manage unauthorized access attempts and anomalies.
Concluding Remarks
Cyber threats targeting financial tools are escalating in complexity and scale, with attacks that occur every minute. The financial sector is also more vulnerable to attacks, making layered security more essential than ever.
Combine proactive security measures, advanced defense mechanisms, and a culture of vigilance to safeguard your financial tools in a hostile, evolving digital landscape. Most importantly, stay updated with the latest threat intelligence and review your security posture regularly.
