re: Identifying And Remediating Security Vulnerabilities In The Cloud
I agree that "Cloud computing can lead to security risks". There are many reasons behind these data security issues in cloud services.- First and foremost is that the architecture is fundamentally based on sharing resources and moving data around for collaboration and scalability.- This contradicts the basic principles of data security and compliance, which focus on restricting access and controlling data flow.- Once the data is out of organizationsG hands and into the cloud, how can security be assured?
If the platform cannot be protected by the organization, then the data itself must be secured before it reaches the cloud.- The primary means to this is in granular, selective data protection, via tokenization or masking, to allow different classification levels.- Tokenized or masked data holds no value to a potential thief, and allows applications to operate on selective portions of the data that bleed through.
The data will then be secured across the enterprise and into the cloud, and only via policy retained at the organizationGs security center can the sensitive data ever be revealed to authorized parties or applications that require it.- A separation of duties, isolating security administration to security personnel, can ensure protection from internal threats.
Since the data itself is secured, this can reduce the requirements for auditing and monitoring, which are also issues in a cloud environment.
Practicing in this way can allow organizations to rest easy, knowing that their data is safe wherever it goes, and continue to take advantage of the numerous efficiencies in cloud computing.
