Data Leak Prevention Strategies

Updated: Apr 18, 2023

With the increasing use of information technologies, information security has become a key concern for companies of all sizes and industries. Information leaks can occur for a variety of reasons, from human error to sophisticated cyberattacks.

These leaks can have serious consequences for companies, including loss of reputation, financial impact, breach of privacy and even legal issues. Therefore, prevention is crucial for the security and success of companies in the digital age. In this context, it is important to implement adequate protection measures to guarantee the confidentiality, integrity and availability of data at all levels of the organization.

Main Reasons

Information leaks in companies occur for several reasons, such as hacking, human error, equipment theft, among others. Below is a list of the main reasons:

  1. Cyber Attack: A group of attackers enters a company's network to gain access to confidential data. They can use techniques such as phishing, social engineering, malware or brute force attacks to enter the system.

  2. Human errors: Employees can make accidental errors that lead to the exposure of unauthorized information. This includes sending an email to the wrong recipient or leaving a folder with such information in a public place.

  3. Device theft: Storage devices such as laptops, tablets and smartphones can be lost or stolen, leaving confidential information on display.

  4. Software vulnerabilities: Vulnerabilities in software or systems that have not been updated can be exploited by hackers to access data.

  5. Insider Fraud: Company employees may disclose what is private for financial or personal reasons. This includes selling information to competitors or cyber criminals.

Some of the information that is disclosed includes:

  • Names, addresses, including email addresses;

  • Phone numbers;

  • Internal projects, such as new product launches;

  • Financial information.

Prevention Strategies

There are some strategies to be explored that organizations can use to reduce the risk of data leaks. Check it out below:

  1. Implement security monitoring systems: These systems alert you to suspicious activity. It is used to supervise user assignment and detect possible threats through specialized software. It integrates traffic monitoring, detection of intrusion attempts and analysis of access logs.

  2. Restrict access to trusted data: Only authorized employees can access it through physical and digital entry controls such as passwords and multi-factor authentication. These types of data should be limited by institutions.

  3. Conduct risk assessments regularly: Used to identify potential threats and define appropriate protection measures. Risk assessments usually involve analyzing the company's systems, processes and information flows to identify potential vulnerabilities and define an action plan to correct them.

  4. Make backups regularly: This action helps to minimize the information, in case the leak occurs. Backups have to be taken in trusted locations, plus testing to be done to ensure they can be fully restored. It is important to avoid loss in case of incidents such as cyberattacks or system failures.

  5. Encrypt sensitive data: This technique provides additional security, as it transforms data into an unreadable format for unauthorized persons. Encryption is used in cases of passwords and financial information.

  6. Adopt security policies: It is necessary to have a well-defined policy on how data should be stored and accessed. It includes the definition of passwords that are difficult to be guessed, entry restricted to what is confidential and the use of security software. Such policies need to be implemented in all departments of the organization.

  7. Conduct employee awareness training: The importance of information security, as well as how to act in incident situations, should be made known to employees, including how to recognize and prevent phishing attacks, correctly use digital devices and systems, and avoid practices that may put the information at risk.

  8. Hire a security team: IT professionals should be hired to help implement and manage data security measures. The team of professionals can work so that companies adopt customized security solutions and that vulnerabilities are recognized.

  9. Perform penetration tests: Simulations of cyber attacks allow vulnerabilities to be identified in networks and systems. Companies should hire security professionals who perform these tests to proactively identify vulnerabilities and mitigate it.

With these prevention strategies, organizations significantly reduce the risk of data leakage and protection against internal and external threats, providing complete security for private information. It is an ongoing process, which must be constantly updated and adapted to new threats and technologies. The video below highlights the dangers of data leakage:

In short, preventing data leakage is a critical responsibility that all companies must assume. With the growing threat of cyber-attacks and the enactment of stricter data privacy laws, it is crucial that companies have security measures in place that effectively protect data and maintain the trust of their customers and partners.
