Samsung SDS is offering enforced security services for its cloud storage based on artificial intelligence and higher level encryption.

Cloud storage is a service offered by hosting companies that allows individual users or corporate clients to store large amounts of data online instead of using internal servers. Samsung SDS offers the service to corporate clients. The increased amount of data created by connected portable devices is boosting demand among companies.

According to Forbes, around 83 percent of all global companies will adopt cloud computing by 2020. Samsung SDS, an IT solution provider, says that cloud security will increasingly become an issue as the adoption rate goes up.

Contrary to traditional data servers, cloud storage can be flexibly adjusted in terms of size and employee access. As storage can be accessed remotely, different security functions are required compared to traditional physical server storage.

“In 2018, there was a total of 300,000 attacks on cloud systems, 3.3 times more than the previous year,” said Han Sung-won, a Samsung vice president in charge of the security business.

“But a lot of the contract terms for cloud services state that clients are responsible for security. This is creating a lot of concern among clients on how to cope with these new attacks.”

To prevent attacks, Samsung is using artificial intelligence (AI) to automatically block attacks that appear similar to ones the AI recognizes from previous incidents.

For a higher level of security, Samsung is developing technology that will prevent hackers from understanding data. A function that is already available for this purpose is white box cryptography. Instead of a fixed encryption key that allows access to a cloud database, Samsung adopted a way to transform this key based on a mathematical algorithm.

Another function under development is enabling the analysis of encoded data. A lot of data breaches happen when consumer data is decoded for analysis.
