GDPR: How to Detect Unauthorized Access to Personal Data

GDPR (General Data Protection Regulation) requires businesses to obtain explicit consent from individuals and ensure the privacy of their personal data before collecting it. It also imposes obligations on businesses to take technical measures for the following purposes: - Monitoring data access and flow across the entire network infrastructure. - Detecting data breaches within 72 hours of their occurrence. - Performing appropriate post-breach activities such as generating incident reports or automatically remedying a breach.

How to detect unauthorized access to personal data with Logsign USO Platform

Logsign USO Platform groups parameters such as the number of log-in attempts, username, and user IP address to collect unsuccessful log-in attempts and creates incidents after a certain limit is passed. Logsign USO Platform warns IT managers via SMS/email if unauthorized user access is detected.

The detection process of unauthorized access begins with Logsign USO Platform correlation techniques by using authentication source logs.


Using multi-correlation processes, user behavior is analyzed, and users are labeled as Attacker, Victim, or Suspicious.


On the Attacker side, after the initial activity initiated by the user, behavior analysis is performed using logs from resources to enrich the logs. Activities performed by the Attacker, both from inside to outside and from outside to inside, are correlated with log activities to be displayed on relevant Dashboard panels.


Malicious access requests detected by the Logsign correlation engine can be detected by the Logsign USO Platform, providing visibility, analyzing them, and sharing them with relevant IT managers via SMS or email.


By centralizing and correlating security event data, it streamlines efficient incident response workflows. Integrated with ticketing systems and other incident response tools, it enables security teams to automate the incident response process. Logsign can trigger automated actions, such as quarantining a compromised host or blocking malicious IP, Username, URL, Domain, and Hash information, to reduce response times and minimize the impact of security incidents.
