Imagine this: Your accounting firm handles a multitude of confidential financial records. Each number, document, and transaction tells a story and holds significant value. But what if this data falls into the wrong hands? The consequences can be disastrous, both financially and reputationally.
Accounting firms are a goldmine for cybercriminals, holding valuable client information, sensitive financial data, and critical business insights. A cyber-attack can mean a potential erosion of trust that takes years to build – or even bankruptcy and business closure.
However, here’s the good news. With the right measures in place, these risks can be significantly mitigated. This article will explore the best practices that every accounting firm should adopt to protect data.
The Importance of Financial Cybersecurity: Risks Threatening Financial Data
Phishing: These scams involve cybercriminals posing as trustworthy entities to deceive individuals into providing sensitive information. For instance, you might receive an email that looks like it’s from a trusted partner, asking you to verify your credentials or click on a link. In reality, it’s a trap to capture your login details.
Ransomware: A form of malicious software that encrypts the victim’s files. The attacker then demands a ransom from the victim to restore access to the data. For accounting firms, this can mean a halt in operations and potential loss of critical financial data – as seen with insurance provider MCNA, who was hit with a ransomware attack in February 2023 that resulted in one of the largest data breaches of the year.
Insider threats: Not all threats come from the outside. Disgruntled employees or those with malicious intentions can misuse their access to sensitive information, leading to data breaches. Alternatively, an ignorant or unskilled employee may make a mistake – accidentally leaking or deleting data, for instance.
Man-in-the-Middle: Here, the attacker secretly intercepts and possibly alters the communication between two parties. For example, when an accountant communicates transaction details with a client, an attacker could intercept and modify the transaction without either party knowing.
5 Data Security Best Practices for Accountants
Before you can defend against threats, you must first understand the vulnerabilities and risks of your firm’s existing security infrastructure. Technology evolves rapidly, and new vulnerabilities emerge just as quickly. These can be taken advantage of by cybercriminals if they aren’t discovered and fixed in time.
One of the largest data breaches of 2023 was the mass exploitation of MOVEit Transfer software, which affected over 1000 global organizations and 60 million individuals, due to a zero-day vulnerability discovered in the software by attackers.
Remember that both external threats (cybercriminals) and internal risks (employee actions) can jeopardize your firm’s data, so assess your systems from both perspectives, and ensure all departments, from HR to IT, are involved in the assessment process to get a holistic view.
One of the most effective ways to enhance security is by ensuring that only the right people can access certain data. MFA acts as an added layer of security beyond just strong passwords by requiring users to provide two or more verification factors to gain access. This could be a smart card, token, fingerprint, or through an authentication app.
Given the sensitive nature of financial data, accounting firms should consider MFA mandatory. It ensures that even if a cybercriminal obtains a user’s password, they would still need the second or third verification factor, making unauthorized access much more difficult.
In the realm of data security, encryption is like a secret code. It scrambles your data into an unreadable code so that even if someone intercepts it, they can’t understand it without the key – the decryption key.
For accounting firms, encryption ensures that sensitive financial data, client details, and transaction records remain confidential and secure, even if intercepted.
Encryption at rest is data that is stored, perhaps on a server or a hard drive, while encryption in transit means data as it moves from one location to another, like during an online transaction. Implementing both types of encryption ensures it remains secure as it travels across the internet or between devices, and even if it’s compromised.
In the event of data loss, whether due to malicious attacks, human error, or technical failures, backups are your safety net. Regularly backing up data ensures that even if it’s lost or compromised, there’s a secondary copy available for recovery. In cases of ransomware attacks, backups allow the firm to restore its data without succumbing to the demands of cybercriminals.
Backups can be stored in the cloud or on physical servers/storage devices. The cloud provides accessibility from anywhere and often comes with built-in security measures – but choose your cloud provider carefully, and understand where and how your data is stored. And while storing your data on physical servers gives more direct control over the backups, it might be susceptible to physical threats like theft or natural disasters.
A well-informed and vigilant workforce can act as the first line of defense against numerous cyber threats. However, the flip side is also true: without proper training and awareness, these same employees can inadvertently become a significant vulnerability.
One of the primary culprits behind data breaches is human error. Simple mistakes, such as clicking on phishing links or misplacing devices laden with sensitive data, can have profound consequences.
Instead of grappling with the aftermath of such errors, it’s far more effective to proactively train employees on cybersecurity, cyber threats, and your firm’s internal policies. By raising awareness about common threats and educating your team on how to counteract these risks, many potential mistakes can be sidestepped altogether.
