What Is A Data Leak?

The common threats or problems of today’s data security are data leak, data breach, and data theft. It’s been seen that all three terms often used interchangeably. All three are not considered as same, just because they are associated with data security. They are all different from each other. Let’s see each of them one after another.

  1. Data Breach: We say there is a data breach when a successful attack is able to secure sensitive information. This requires a successful cyber attack to secure sensitive data.

  2. Data Theft: Data theft is nothing but exfiltration. When an unauthorised user accesses the data and takes it allegedly without the owner’s permission for any means. This is considered a cyber attack.

  3. Data Leak: Data leak is not limited to the unauthorized transfer of the data either electronically or physically but also publishing it on public platforms for sale. Most of the data leaks were published on the dark web. This won’t be necessarily a cyber attack. Data leak could happen because of accidental and misconfiguration reasons as well.

Common Vectors Of Data Leak:

Data leak could occur via web, email, storage drives, flash drives, optical drives, direct connections of digital devices like smartphone and laptops. But it can also occur in non electronic forms like taking print or note of the sensitive data, and even verbal transmission of data is also considered as data leak. In some cases, data leak could be due to accidental exposer and misconfigurations.
