KEY CHALLENGES FOR CLOUD STORAGE SECURITY

There is a rising trend seen in the adoption of cloud services by organizations and enterprises. Along with this has emerged an increase in the cloud storage security challenges that organizations and enterprises are facing. This article provides you with an update on the key challenges in cloud storage security.

KEY CHALLENGES FOR CLOUD STORAGE SECURITY-1

With businesses taking advantage of cloud storage and making it an integral part of their infrastructure, cloud storage has become the key technology for storing data. And here, along with the advantages of storing the data in the cloud, there are a few basic challenges with the security.

The primary concern would be that the data might move beyond the security of the organization. A proper cloud-based storage solution can safeguard the data by keeping it safe. The top security challenges are described below which helps to analyze and also to keep the organization data safe.

1. In what way does the cloud storage solution block the data leakage?

The cloud serves as a multi-user as well as a third party environment where the resources are shared as well as being the gateway to the customer’s data. It is risky to share the storage hardware to the vendor. Apart from being risky, the privacy laws control the essential data of the organization. Data leakage is always a major security issue. It may happen due to access by government agencies or an accident or a hacker. The best method to follow would be sending only encrypted files to the cloud from the beginning and using the strongest encryption technique. Any weaker encryption technique may again cause risk to the data. Depending on the cloud provider or an intermediary organization for encrypting the files would leave the organization with no options, except to rely on trust. This may happen because the cloud provider can decrypt the data as well. All data has to be encrypted completely before it leaves the premises. Even though the cloud is managed by leading or bigger companies, they still are not to be trusted.

2. Does your organization have exclusive credentials for the cloud?

Securing the data with your own credentials is one of the important challenges. By maintaining unique credentials, the files will be separated from other company’s data and also prevent others to log into your account and make any changes or delete the files. In the storage pool, access is based on the credentials. If your organization is piled up together with another and you share the same credentials, there is every chance of others obtaining the credentials and accessing the data. They might not be able to interpret it, assuming that the data is encrypted but they can still delete the data.

3. Is your data secured during transit?

Files on the cloud can be accessible if there is no strong encryption and unique credentials. Risks may occur while transmitting the data. There is no need of a secure connection for the encrypted files to be sent as it results in double encryption. But, assuming the worst and taking measures to safe guard any intruding by sending and fetching the data on a secure connection is always a good step. This prevents the exposure of the cloud metadata. The data should not be translucent in the cloud. No filenames or timestamps should be seen once the data leaves the organization boundary, which may help in interpreting the data.

4.Who are holding the Crypto keys?

Mishandling of the key management without addressing properly, creates a risk that users do not activate cryptography which compromises the security. The management has to be simple such that the encryption is automatic and there is no way of turning it off. This way it makes the key management simple without even the user’s awareness. This way, the data is in a secure mode and there is no chance of a third party to decrypt and access the data to the cloud. The keys are also to be guaranteed so that it’s highly difficult to fetch and access the data.

5. How is the performance effected?

Performance should not be effected by maintaining a strong security strategy.  Encryption and decryption process should happen with no adverse impact on the performance. Encrypting the data to the cloud and decrypting the same from the cloud, should not create an impact on the performance of the user experience either.
