When we talk about cloud computing, it refers to storing a company’s data in third-party data centers owned and managed by the chosen cloud provider. Before the storage of data in clouds, Organizations used to store their data in their systems. With the emerging cloud technology, complete databases, software applications required, customizations to the software can be stored in the clouds. The internet is the medium through which these can be accessed. This eliminates the need for personal physical hardware to store the data. Most Organizations are now switching to cloud technology. Still, the matter of concern here is: Is Cloud Computing secure enough to protect the data in every condition. Looking at this complex architecture, we need not mention here that despite tight security of the data in clouds, there are still some unresolved issues that fall into two major categories:
- Security concerns for cloud providers (organizations providing services to store the data on the cloud)
- Security concerns for customers (companies or organizations who use the services offered by cloud providers)
There are fears that cloud computing is comparatively less secure at some places than their security (which are now outdated) approaches. It may be because of servers on which the data is stored are controlled by third-party vendors. But Cloud storage providers promises accountability of data security. Cloud storage providers protect data for their platforms through authentication, access control, and encryption. In addition to that, enterprises can also protect their sensitive data via their self-initiated security measures.
Now let’s have a look at the risk of storing data in the cloud:
Data security provided by the cloud is upright, but it’s not that no one can breach through these security measures. Cybercriminals can get into those files, whether by guessing security questions or bypassing passwords. One of the reasons can be when the business starts transferring the data in the cloud. They assume that Cloud Service Providers had complete responsibility for keeping the data secure. Though Cloud service providers take full responsibility for infrastructure and software security but to be true, it’s the businesses who are ultimately responsible for data security or how their data is being used and accessed. One of the significant risks with cloud storage is privacy. Even if data is not hacked or publicized, it can still be decrypted and handed over to the legal government requests.
The service providers’ complete decision to hand over the data or keep it private as promised to the customer.
cloud providers take security measures
These controls are provided to protect the customers from flaws in the system and reduce any cyber-attack effect. The outcome of the service providers’ hard work in various types of controls to maintain cloud security.
They can be categorized as:
Warning messages: These controls are there to reduce attacks on a cloud system. They are the warning sign to attackers conveying that they can face adverse consequences if they go beyond limits.
Preventive controls: Preventive controls tighten the security against incidents such as cloud users’ authenticity by making sure that unauthorized users cannot access the cloud data. The cloud users should be identified before giving them access to the cloud.
Detective controls: Detective controls work to detect and react according to any incidents that occur at the time of an attack. A detective control signals the defensive or corrective controls to look into the issue. System and network security vigilance, including intrusion detection and preventive provisions, are installed to detect cloud systems attacks and supportive communication methods.
Corrective controls: Corrective controls reduce the consequences of an incident caused by data containing errors, especially by limiting the damage caused by it. They are handed over the care during or after an incident. Corrective controls can take place by taking system backups to rebuild a system containing errors. Organizations make several strategies to make data secure in the cloud.
Cloud data encryption: Encrypting data is the process of altering or encoding data before it’s being moved to the cloud storage. Cloud service providers can encrypt the data completely or partially sensitive data. They also provide encryption keys to the authorized person to decrypt the data if needed. Keeping in mind data security, this is first in the line of defense for any cloud system. Complex Algorithms provides the base to encrypt the data. To decode the encrypted file, one needs the encryption key. Encrypted data also can be hacked, but to decrypt data, requires massive computer processing power, scientific software, and a lot of time. Password protected encrypted can be only seen by authorized users. Organizations using cloud services should state the policies related to data security very clearly. Passwords that are easy to guess will not work, and only the authorized and trustworthy persons should know the passwords.
Cloud services are secure from various cyber-attacks and even natural calamities. They also provide measures to backup and restore data. But backing up a company’s sensitive information on in-house servers is a brilliant job. This is to be sure that related crucial information is not lost in case of problems with the service provider. It is also smart to validate the services provided by the cloud provider. It’s essential to keep an eye and audit continuously to keep track of the business activities and manage risk effectively.
So, we can say that cloud infrastructure almost reaches this goal to provide data security. Data is safe with the cloud provider, but with some necessary precautions to ensure everything works smoothly. This is mostly dependent on company policies related to passwords and encryption.
