Data Encryption
What is encryption, anonymization and pseudo-anonymization of data?
Data security policies can include different ways to protect data. They differ in the technology used, among other things, but have the same effect.
Data encryption
It is a set of techniques involving encryption of sensitive information that should remain confidential. With this procedure, it is possible to block unauthorized access. However, encryption of data in the cloud does not make it inaccessible to people with the appropriate permissions. They can be accessed with a decryption key.
Anonymous
Pseudo-anonymization
Unlike anonymization this is a fully reversible procedure. In this case, too, the data is processed so that it cannot be attributed to a specific person, but with the use of additional information it will be possible. Importantly, the so-called additional information should be collected separately and under supervision. Access to them should be properly authorized.Â
What kind of data can we encrypt?
- End stations - key element of data protection implemented on devices such as laptops, computers, smartphones
- Databases - Encryption of sensitive data stored in SQL and NoSQL databases.
- Applications - Integration of encryption into applications to protect sensitive data.
- Data in the cloud - Encryption of data stored in cloud services.
- HSM (Hardware Security Modules). - secure management of cryptographic keys.
- PKI (Public Key Infrastructure) - security of keys and certificates.
- Email - protects the contents of a message from unauthorized access, ensuring the confidentiality of communications. Thus, even if a message is intercepted, its contents remain unreadable without the appropriate encryption keys
Models of solutions dedicated to encryption
Encryption can be implemented in several ways:
Encryption of data during transmission
is to protect data in motion within the network.
Encryption of archive data
is to protect collected and cataloged information that is not currently in circulation. The protection can be applied to both data on servers and individual user devices.
Data encryption in use
is to secure resources even while they are being used by employees, such as through business applications.Â
Benefits of implementing data encryption
- Protection of sensitive data - Encryption makes the data unreadable to unauthorized parties, minimizing the risk of leaks.
- Meeting regulatory requirements - Encryption helps with regulatory compliance, such as RODO, NIS2, DORA.
- Security against theft - Even if the data is stolen, it will be useless without the right keys.
- Increase customer confidence - Secured data builds customer confidence in the company.
