Top Tips to Prevent Data Theft For Your Business

In the digital age we live in today, data theft has become one of the greatest threats to businesses around the globe. 

Have you ever really stopped to think about how secure your business data is? Do you know the risks of having the data you collect for your business mishandled? Data theft can destroy a business through loss of revenue, ruinous reputation, and loss of customer trust. By taking the right steps, your business can lessen the chances of a data breach.

An IBM report stated that the average cost of a data breach is over ₹32.8 crores, with small businesses deemed the most vulnerable. Almost 20 billion records were exposed in 2020 due to data breaches.

Equifax, one of the largest credit reporting companies in the United States, had a massive data breach that put the personal information of about 147 million people at risk. Hackers exploited a vulnerability in the Apache Struts web application framework that Equifax did not patch after a public announcement regarding the vulnerability. The data that was stolen included names, Social Security numbers, birth dates, addresses, and in some cases, driver’s license numbers.

The breach was not only incredibly damaging to the reputation of Equifax, but also led to a settlement of ₹5.74 billion to the consumers and regulators affected. Although this is a large amount of money to spend on staff salaries and new policies, the lessons to be learned are clear. Keeping your patches up-to-date, proactively auditing your security, and developing policies to improve your network security measures throughout the planning phase to incorporate every opportunity to prevent a breach is extremely important. 

The breach of Equifax by unknown hackers demonstrates the consequences of not addressing known vulnerabilities and also shows why it is important for companies to prioritize the development of organizational policies focused on cybersecurity and the ability to protect sensitive customer data.

What is Data Theft?

Data theft is the unlawful acquisition, obtaining, or appropriation of confidential, sensitive information, often for illegal reasons. Stolen data can be personal information, financial data, intellectual property, or proprietary business information. Such information can be used to commit identity theft, fraud, corporate espionage, or other actions that can cause significant harm to individuals and organizations.

Awareness of data theft is at an all-time high, with cybercriminals developing innovative methods to steal valuable data. That's why it is crucial to keep your business protected from data theft, it is not only to keep your data safe, but also to protect your customers’ trust and your business reputation.

How to Identify Data Theft For Your Business

Data theft is a serious threat that can result in significant financial losses, legal consequences, and long-term damage to your company’s reputation. While it’s essential to implement strong preventive measures, being able to identify data theft quickly is just as important to minimize the damage. 

1. Unusual System Behavior or Slowdowns

One of the first signs of potential data theft can be unusual behavior within your business’s IT systems. If you notice a significant slowdown in the system or abnormal spikes in traffic, this could indicate unauthorized access or data exfiltration. Cybercriminals often install malware or use tools to extract data from your network, which can overload the system.

2. Unexplained Access to Sensitive Data

If you notice that certain employees or users are accessing data that is outside the scope of their responsibilities, it could be an indication of potential data theft. For example, an employee in accounting may begin accessing customer personal information, which is irrelevant to their job function. This unauthorized access could be a sign that an internal or external threat is at work.

3. Sudden Increase in Data Transfer or Large Data Downloads

A sharp increase in data transfer or large-scale downloads from your company’s network can indicate that data is being exfiltrated. If you notice significant spikes in the volume of data being accessed or downloaded, it could suggest that hackers or insiders are attempting to steal valuable business data.

4. Suspicious User Accounts or Login Attempts

One of the most common methods of data theft is unauthorized access via compromised user credentials. If you notice an unusual number of failed login attempts or login attempts at odd hours (such as late at night or on weekends), this could indicate that a hacker is trying to gain unauthorized access to your business systems.

Top Tips to Prevent Data Theft For Your Business

1. Educate Your Employees on Data Security Risks

Human error is often a key factor in data theft. Employees may unknowingly expose sensitive information by clicking on malicious links, mishandling data, or falling victim to phishing attacks. As such, training your employees on proper data security practices is critical.

2. Enforce Strong Password Policies and Multi-Factor Authentication

Passwords are often the easiest point of entry for hackers. Weak passwords or reused passwords across accounts can lead to massive vulnerabilities in your system. To protect against this, enforce a strong password policy. Passwords should be long, with a combination of upper and lowercase letters, numbers, and symbols. Make it a rule for employees to change their passwords every few months and to use different passwords for different accounts.

In addition to strong passwords, implement Multi-Factor Authentication (MFA). MFA adds an extra layer of security by requiring two or more verification methods before granting access. This could be something the user knows (a password) combined with something they have (a smartphone app generating a code). MFA has been shown to significantly reduce the risk of unauthorized access. According to Verizon, 81% of data breaches involve compromised passwords, making strong password policies and MFA crucial in preventing data theft.

3. Encrypt Sensitive Data

Encryption ensures that even if someone gains unauthorized access to your data, they cannot read it. Encryption works by converting your sensitive data into a format that can only be read with a decryption key. This is essential for protecting confidential business and customer information.

Encryption should be applied both to data at rest (such as information stored in databases) and data in transit (such as data being sent over the internet). For example, sensitive customer data, such as credit card details, should always be encrypted during transactions, both online and offline. Additionally, end-to-end encryption in messaging platforms can further secure communications, preventing interception during data transfer.

4. Implement Secure Network Practices

Hackers often attempt to access a business’s data by exploiting vulnerabilities in its network. A secure network forms the backbone of your data protection strategy. Start with firewalls and anti-malware software to prevent malicious attacks. These tools block unauthorized access and alert you to any suspicious activity on your network.

Ensuring your network is regularly updated with the latest security patches is also essential. Cybercriminals often exploit outdated software and vulnerabilities to infiltrate systems. As soon as updates or patches are released, they should be installed immediately to prevent these attacks.

5. Limit Access to Sensitive Information

Not every employee needs access to all of your business data. By implementing role-based access control (RBAC), you can ensure that employees only have access to the data they need to perform their jobs. This minimizes the risk of internal data theft and reduces the amount of sensitive information at risk.

Additionally, regularly review and update employee access permissions. When employees leave your company, their access rights should be promptly revoked to prevent any potential misuse of company data.

Data theft is a constant risk, irrespective of company size. But you will minimize your risk of data theft by taking the necessary steps to educate your employees, utilize unique passwords and MFA, encrypt sensitive data, and secure your network.  Protecting your business from data theft is not a one-time event, data security is an ongoing endeavor that takes diligence, tools, and a proactive approach to information and data security.
