The motivation to prevent these cyber events should be more than just to avoid identity theft. How to Prevent Data Breaches and Data Leaks in 2023 Exfiltrated data posted in dark web forums.Some examples of security incidents that lead to data breaches include: Learn more about social engineering > What is Considered a Data Breach?Īny event that exposes sensitive data due to cybercriminal activity is considered a data breach.Įxamples of Events that Cause Data Breaches The bounty from these attacks provides just enough ammunition to access a private network and initiate a data breach campaign. This is because the information exposed in a successful social engineering attack isn't always sensitive enough to be considered a breach. Though an external factor causes these events, social engineering could also be considered a data leak vector. Weak passwords (because they can be easily discovered with brute force methods).Cloud storage misconfigurations (such as insecure Amazon S3 buckets).Some examples of security incidents that cause data leakage include: ![]() Medical or Personal Health Information (PHI).Personal Identifiable Information (PII).The types of data commonly exposed in a data leakage include: Security policies and data security strategies must consider the diversity of data leak types to maximize the potential of mitigation efforts. The inclusion of physical events widens the scope of data leaks and further differentiates them from data breaches, since breaches only occur in the digital realm. When sensitive data is stolen from either a data breach or a ransomware attack and published on the dark web, these events are also classified as data leaks.īesides insider threats, a physical data leak could include insecure physical devices storing sensitive information, such as passwordless external hard drives. Physical data leaks, such as insider threats, are more difficult to intercept because you're usually contending with a strategizing adversary rather than a static digital exposure. These events can be both digital and physical. Learn more about the differences between data leaks, data breaches, and data loss > What is Considered a Data Leak?Īny internal event exposing confidential information to an insecure environment that isn't a cyberattack is considered a data leak. Data loss prevention (DLP) strategies aim to confine sensitive data within a set boundary to prevent its transfer into hostile environments. Data loss occurs when sensitive data is irrevocably lost, either through theft or deletion. Internal security teams could overlook a software vulnerability exposing confidential data, or insider threats could purposely establish attack vectors for hackers to access sensitive data.ĭata loss is another term commonly associated with data leaks and data breaches. This trigger is usually an action performed by a cybercriminal, such as a phishing attack.ĭata leakage, on the other hand, results from an internal trigger. Get your free data breach prevention guide >ĭata breaches require an external trigger to initiate a process leading to data compromise. The primary differentiator between the two events is the impetus leading to this objective. The outcome of data leaks and data breaches is the same - sensitive data is compromised. ![]() These cyber events are more common, and there are plenty of examples supporting this claim. ![]() Simply put, a data leak is when sensitive data is unknowingly exposed to the public, and a data breach is an event caused by a cyberattack.Īn example of a data leak is a software misconfiguration facilitating unauthorized access to sensitive resources - such as the major Microsoft Power Apps data leak in 2021.Īn example of a data breach is a cybercriminal overcoming network security controls to gain access to sensitive resources.
