ANNEX 2
SECURITY MEASURES
Taking into account the best practices, the costs of implementation and the nature, scope, circumstances and purposes of processing as well as the different likelihood of occurrence and severity of the risk to the rights and freedoms of natural persons, Extendity undertakes the following technical and organizational measures:
1. Encryption measures
Measures by which readable text / information is transformed into unreadable, difficult-to-interpret character strings (encrypted text) through encryption methods.
Description of encryption measures: symmetric / asymmetric encryption is applied to communications between participants and/or servers.
2. Physical access control
Measures that physically prevent unauthorised persons from accessing IT systems and data processing equipment used to process personal data, as well as confidential files and data media.
Description of physical access control measures: restricting unauthorised access to data processing systems by locking premises, using access cards, and other locks.
3. Logical access control
Measures preventing unauthorised persons from processing or using personal data.
Description of logical access control measures: managing system access and work sessions, using secure passwords, automatic computer locking mechanisms, and encryption of data media.
4. Data access control
Measures ensuring that persons authorised to use data processing systems can only access personal data according to their granted access rights and that data cannot be read, copied, modified, or removed without permission during processing, use, and storage.
Data access control measures: prohibition of reading, copying, modifying, or deleting data in the system without authorisation, use of authorisation mechanisms and access rights upon request, application of a “clean desk” policy, and automatic device locking when away from the workplace.
5. Separation rule
Measures ensuring that data collected for different purposes is processed separately and isolated from other data and systems to prevent unintended use for other purposes than those for which they were collected.
Separation measures: separate processing of data collected for different purposes, based on authorisation measures, use of software and information systems grounded in client separation, and separation of development and production environments.
6. Transmission control
Measures ensuring that it is possible to verify and determine to whom personal data may be or has been transferred, using data transfer equipment.
Transmission control measures: during electronic transfer, encryption measures prevent data from being read, copied, modified, or removed, with records kept of data transfers and users conducting the transfer.
7. Availability control
Measures ensuring that personal data is protected against accidental destruction or loss.
Description of the availability control system: data is stored in a reliable environment with a backup procedure.
