As a result of examining the data breach notification within the framework of our authority and duty; With the Decision of the Personal Data Protection Board dated 20/01/2020 and numbered 2020/50;

 

It was concluded that

 

  • The fact that the data breaches that took place on 01.08.2018 and 21.10.2018 were detected on 02.07.2019, approximately one year later, indicates that the Company does not have a log record/tracking alarm system for the transactions carried out or is not used effectively and the necessary controls are not made by the Company,
  • The fact that the personal data is seen by third-party vendors/providers via the URL is an indication that the tests performed during the web page design phase are insufficient or that the necessary tests are not performed.

 

The tests carried out during the design phase of the web page were insufficient and the violation detection was made late due to the lack of tracking/alarm systems regarding the transactions that took place, within the framework of paragraph (1) of Article 12 of the Law on the Protection of Personal Data (Law) numbered 6698, an administrative fine of 50.000 TL is imposed on the data controller who does not take the necessary technical and administrative measures, in accordance with subparagraph (b) of paragraph (1) of Article 18 of the Law,

 

Considering that

 

  • Although it is seen that the violation was detected by the data controller on 29.05.2019 and the Board was notified on 06.06.2019, an investigation was conducted by the data controller residing abroad to determine whether the relevant persons in Turkey were also affected by the so-called violation after the detection date.

 

this period is considered to be reasonable, it has been decided that there is no action to be taken within the scope of the Law in this regard.

 

What Were The Shortcomings Of The Institution?

 

– The fact that the breach event can be detected by the Data Controller after a long time, the security controls are not carried out regularly, therefore the technical and administrative measures taken by the data controller in terms of personal data security follow-up are insufficient.

 

– Late notification of the breach by the Data Controller to the Personal Data Protection Board

 

– Failure to effectively implement the policies regarding personal data security by the Data Controller.

 

What Precautions Should Be Taken?

 

– Administrative and technical measures should have been effectively implemented by the Data Controller and made into a corporate culture.

 

– The data security measures taken by the Data Controller should have been implemented more frequently.

 

– By raising awareness in the institution by the Data Controller, the breach event should have been detected earlier.
