How to Prevent Data Leaks

With the rapid advancement of digital technology and the advent of the Internet of Things (IoT), data has experienced exponential growth, posing unprecedented challenges for organizations in safeguarding the confidentiality, integrity, and availability of their data assets.

In this context, data leak detection and response solutions have become a crucial component of robust cybersecurity strategies. To address these issues, enterprises must employ advanced technologies to detect and respond to data leaks, ensuring the protection of their valuable data assets.

Definition and Causes of Data Leaks

Data leaks and data breaches both involve unauthorized disclosure of information, albeit with differences in methods, scale, and impact. Typically, data leaks occur when an unauthorized party deliberately attempts to gain access to sensitive information.

On the other hand, data leaks may result from errors in configuration, system malfunctions, internal threats, and inadequate security measures. However, unintentional leaks do not imply a lesser concern compared to malicious ones, as both scenarios can have serious security and financial implications for any organization.

Causes of Data Leaks

Some factors leading to internal data leaks include:

  1. Errors in data storage, system, or network configuration
  2. Internal threats and poor access management
  3. System crashes, errors, and failures
  4. Outdated software and tools
  5. Social engineering attacks
  6. Zero-day vulnerabilities

Addressing Data Leak Issues

  1. Attack Surface Monitoring

The expansion of the attack surface is identified as one of the most critical security and risk management trends in 2022. This involves the increased risk associated with the use of IoT devices, cloud applications, open-source code, and even social media. The solution is not merely reducing the digital footprint but taking responsibility and developing greater capabilities to identify potential vulnerabilities and entry points.

  1. Data Detection and Response (DDR)

DDR solutions represent an advancement over traditional data leak prevention plans, as they focus on a data-centric approach. In comparison to the narrow approach of traditional Data Loss Prevention (DLP), DDR can enhance comprehensive visibility by using advanced technologies such as machine learning and behavioral analysis to detect abnormal activities, suspicious patterns, and potential data leak attempts. Therefore, DDR methods are better suited to capture and mitigate zero-day attacks.

  1. Data Leak Prevention Policies

Organizations are guided by policy documents in all areas, and data security should not be an exception, especially when it comes to data leaks. Implementing company-wide data leak prevention policies is one of the primary steps to mitigate threats caused by internal negligence. Ideally, such policies will define acceptable data usage, educate employees on best data security practices, and establish incident response protocols to effectively address data leak events.

  1. Endpoint Protection

The rapid increase in the number of endpoints within global organizations has been a significant concern. Traditional security measures, such as antivirus software, host-based firewalls, intrusion detection systems, and other signature-based security solutions, have not been as successful as anticipated. According to the 2022 Endpoint Security Report by Cybersecurity Insiders, 85% of organizations expect their security systems to be attacked within the next 12 months, and 34% claim to lack sufficient understanding of their endpoint environment. To avoid data leaks, organizations must prioritize advanced endpoint protection solutions to defend against malware, unauthorized access, and data leaks.

  1. Privileged Access Management

Users with privileged access to critical systems and data are most vulnerable to harmful data leaks. Therefore, attackers find it easier to identify and manipulate vulnerabilities by elevating access privileges. In addition to enforcing robust authentication and authorization mechanisms, it is best to grant privileged access only on a need-to-know basis and monitor such access.


By deploying these solutions, enterprises can proactively protect their valuable data assets, enhance incident response capabilities, and maintain trust with stakeholders. If data is indeed considered the “new oil,” efforts must be made to protect it from falling into the wrong hands. As more organizations embrace this challenge, people will better ensure the security of their data.
