Cloud Computing brings you a lot of convenience. And Encryption with Cloud cryptography makes sure that you need not sacrifice your safety for this. For protecting the data stored in the cloud, Cryptography allows you to employ encryption techniques. While being secured by such encryption, the cloud data & services can be easily accessed and shared among users. This allows secured exchange of information and protects confidential data.
For the data which is beyond our control to be protected, cryptography paves the way. Since we no longer hold control over the cloud data physically, the only way to protect it is to encrypt it cryptographically and having the cryptographic key in our hands.
Cloud security with Cryptography
Cloud computing provides virtual infrastructure for computing where the data and applications can be stored. Although it is gaining popularity, it faces the issue of security since the data is handled outside the reach of its owner. As there is no security provided against untrusted cloud operators, businesses face the challenge of storing confidential information such as Financial records, Medical records, or high-impact data. To balance security with performance, many cryptographic tools are being designed by different companies.
Cryptography can be extended to cloud in different ways of encryption. Most of the users chose to encrypt the data before it is uploaded on to the cloud. This is deemed to be more secured as the data is locked before it leaves the organization and only the authorized receiving end can decrypt it with their decryption key. Some services provide encryption for the data after receipt. This ensures that the data storage and transmission is secured through encryption, by default. Some services may not enable encryption techniques. But it is still needed to use encrypted connections for ensuring data safety such as HTTPS, SSL, etc.
The changing technological environment poses advanced and sophisticated threats for cloud services, virtualization and mobility. Data-centric approach protecting sensible and confidential information is needed by the organizations to provide guard against such threats. Data-security solutions should be provided by companies that ensures consistent protection for data including cryptographic key management and Cloud data security by encryption. This platform for encryption and cloud data security can also employ key management techniques and robust access controls which can help the organization to efficiently and cost-effectively encrypt the data addressing the concerned security problems.
Benefits & Setbacks for businesses
As most of the companies treat cloud cryptography as providing a strong protection layer over the data to avoid hacking, breaching, or any other kind of malware practices. Benefits of such a technique for your business include:
Privacy: For the sensitive data such as client information, it ensures the data to remain private reducing the chances of theft or manipulation from unauthorized users.
User Notifications: Cryptographic keys ensure that only authorized users are enabled to access data. And the businesses can enable notifications if any unauthorized user tries to access such data.
Enhanced security: Static data can remain more protected but this becomes more vulnerable during transmission. Encryption prevents this from happening.
Along with benefits, businesses must make sure of setbacks too for making an efficient decision of how to protect their data. The following are the setbacks of this method:
Cost: Since the systems are more advanced, the technology for encryption is also more sophisticated which results in high-cost maintenance.
Data Recovery: At times, the security over the data leads to over-protection which makes it difficult to recover the data at receiving end. Hence, although more keys lead to more security, it also involves more difficulty to enter server.
Glitches: Handling the data in IT may consist of high protection over data for its storage and transfer. But it still has high possibilities of server glitches.
Cloud cryptography, on the whole has both benefits and setbacks. But it is necessary for the businesses to ensure the safety of their data when they are using the storage infrastructure outside of their reach. Different kinds of Encryption techniques allow organization flexibility to choose from based on their requirements.
