June 6th The most stringent privacy protection legislation in the history of the European Union, the "General Data Protection Regulations" (GDPR), gives EU users more power to control personal data. It also forces organizations to take stronger actions in storing or processing EU personal data. Security and privacy controls. Although there is currently no single tool that can help companies fully meet GDPR compliance, there are a number of tools that can help companies work toward compliance. Security Information and Event Management (SIEM) tools are among them.
Why can SIEM tools help companies "comply"?
Safety Information and Event Management (SIEM) tools can play an important role in GDPR compliance. The adoption rate of SIEM has increased significantly in the past few years because the complex compliance requirements including PCI DSS and HIPAA require advanced threat monitoring and management measures. Therefore, SIEM has always been the first choice for information security professionals.
SIEM also fits in with several of the demands of GDPR. The GDPR emphasizes in several important articles that the organization must:
Keep a record of the activity of its processing data;
? Record the type of data being processed;
The purpose of clear data processing;
? Record the parties to whom the data is shared;
? Set data retention limits for processed data;
ç¡®ä¿ Ensure that appropriate security measures are taken to protect the data.
SIEM can serve as a focal point for all data collection and analysis activities, providing intelligent analysis of system logs and network information. Once the SIEM is configured correctly, it can look for malicious behavior and system activity and alert the enterprise's security event team before the security event deteriorates into an impact data breach event.
At the same time, data captured by SIEM may contain personally identifiable data. Therefore, understanding the potential opportunities and threats of using SIEM tools to help meet GDPR compliance is critical for companies or organizations.
Identify the root cause of the data breach
Enterprises can adopt SIEM and use it to identify security events in the network after it is properly configured. This helps to prove that the company has deployed appropriate security controls to process EU user data. In addition, the SIEM solution also allows corporate analysts to quickly detect, prevent and investigate potential data breach incidents. Research analysts at the SANS Institute stated in their "2017 Data Protection Survey" report that SIEM and log data can be used to determine the root cause of data breaches.
When companies report influential data breaches to the European Union, companies need to provide detailed information to report the extent of data leakage, such as which data is accessed, which data is affected, and what are the risks to the EU data subject. Many of these problems can be answered in the SIEM solution.
Helping to meet the "right to be forgotten" of GDPR Article 17
SIEM can also help companies meet the “right to be forgotten†of GDPR Article 17. If the EU mandates, companies need to deploy a mechanism to delete data, in addition to the need to prove that personal data has been deleted. Enterprises can extract log data from bulk deletions to verify that the data has been deleted. SIEM's log data also allows companies to understand who is accessing the data and when it is processed. The more data a company provides to EU regulators, the better it will be for them. The SIEM can serve as a focal point for managing these GDPR compliance requirements and handling event reporting during incident response.
Pay attention to personal data in log processing
According to the definition of GDPR, personal data includes information such as name, email, and IP address. When an enterprise processes log and network data, SIEM solutions may retain this data, causing the company to violate regulations. To mitigate this threat, companies can choose to use kana and/or encryption solutions.
The company can separate any personal data in the log and use a pseudonym so that it can only be accessed when needed.
When the data is processed by the pseudonym, the sensitive data is replaced with a value that does not allow identification of the data body.
When data is encrypted, businesses can encrypt data on endpoints in a fully encrypted manner and monitor these data through SIEM alerts
In addition, companies can encrypt static data stored in backup and storage infrastructures. SIEM can track access to these locations and monitor any attempt to move data out of the network. Some SIEM tools themselves contain pseudonyms or data masking capabilities, so companies can also consider SIEM as a platform for managing and monitoring GDPR compliance.
In general, SIEM solutions help companies protect data. It is worth emphasizing that SIEM is not the ultimate tool for meeting GDPR compliance, but it can address some of the technical and safety control requirements required by GDPR.
