Youssef Arbach: VP Security
Businesses are moving to the cloud. The cloud offers services that will make their IT infrastructure cheaper and more scalable with less maintenance. Although the cloud is very interesting for businesses, there are major security and privacy concerns. Due to fear or strict regulations, businesses struggle with secrecy, control and ownership of
data in the cloud. For these reasons most businesses choose to go for private clouds and even legacy on premise solutions, making unnecessary costs and effort.
Secrecy of data mainly depends on encryption and key management. Cloud providers provide encryption services but hold the keys to this encryption and are therefore a shared reader of the content. If data is encrypted before it is stored, most cloud providers nowadays have enough computation power to break ciphers that are considered safe.
Up until now there is no technology that will leverage the power of cloud scalability whilst maintaining full secrecy of data that is stored. One solution next to encryption that would increase secrecy is to chunk data and distribute it over multiple cloud containers or providers. Although you hold the keys, the increase of secrecy with this approach might still lead to partially readable data if the cipher is broken.
