Nowadays, everything is stored in the cloud, which affects our lives and industry very much even if it is not physically visible to us. Because of this one of the major concerns related to a cloud are IT security and its privacy. Each and every day there is a news related to breaches in the server system, confidential leaks in social media network, spying, and all other security-related incidents. All such things increase the risk and fear in user's mind because it can happen with them also.
Many years ago, when users are concerned about IT security, the firewall technology comes into account and becomes really popular. Moreover, the organization’s which are creating firewall technology had an amazing idea. They acknowledged that selling only a piece of firewall software program did not bring them high profit. Thus, they buy the low-end computers, which can easily satisfy the minimum requirement that is necessary to run the firewall software. After that, they just painted the box with a red color and sold their product beautifully. However, the representative was able to tell users that firewall is enabled. They show the red box also and make users feel more comfortable because there is a dedicated physical box.
Therefore, when a user talks about the cloud services, there are few questions that strike in the customer mind. How secure is cloud computing, how a user can safeguard the environment with cloud control? Considering all such queries, a complete guide on security related to cloud computing is discussed here.
Private Versus Public Cloud: Which is More Secure?
When it comes to security in cloud computing, the type of cloud one is using is also one of the major factors. Thus, we have covered all major points related to public or private cloud.
- Private Cloud: The private cloud is also known as an internal or enterprise-level cloud where all data is secured behind a firewall. It is more beneficial for the organizations that already use an expensive data centers. It is because they can easily use their current infrastructure. But, the major drawback of using a private cloud is that all updating of the data centers, management, and maintenance is the responsibility of the organization only that is really expensive. On the other side, private clouds provide a great level of security as they share very few resources with other organizations.
- Public Cloud: The major difference between the public and private clouds is that in this a user is not responsible for any type management. All important data is stored in the data center of providers and that particular provider is responsible for data center’s management and maintenance. It is used by most of the organizations as it decreases the lead times while testing and deploying a new product. The major drawback of public cloud is that users feel security is lacking behind.
Now, after understanding all about public and private cloud, it is clear that large organizations may go for a private cloud to have an advanced level of security. On the other hand, a smaller business might go for a public cloud.
How Actually is Traditional IT Infrastructure Secured?
Before switching to cloud security, first, understand how the infrastructure of traditional IT with the medium-sized company is secured mainly. They basically take help of any of the following to protect their infrastructure:
- Physical resources
- Network partition
- Firewalls
- Correct management of user ID and password
- Security area management
- Software with some unsafe code
- Perform complete system security check
- Encrypt the most important data and create network traffic
- Use intrusion detection & prevention systems
- Monitor all unauthorized activities
- Maintains logs and use alerts
By using a robust security policy, high level of security tools and best practices will provide a high level of IT security. Apart from this, the organization may get some sort of certifications such as ISO27002 standard. One can secure the traditional IT environments at any level depending on the effort and money spends on them.
Approach Used by the Cloud to be Secured
If a user wants to secure cloud, then or she can use same IT security policies, industry best practices, and standards in the cloud also. If a user thinks of using similar approaches as a traditional IT infrastructure and perform virtualization of components that are already running on a dedicated hardware. Then, surely there are some things that change. For example, deletion of standard virtual server occurs more quickly compared to same on a dedicated hardware. But there are some things that remain as it is such as security policy of an organization.
Switch to CloudCodes for Better Cloud Security
However, there are still some questions in users mind like how to reduce the unauthorized deletion of virtual instances? How to be sure that data is completely secured in the cloud? To get an answer to all such questions, one is suggested to take help of some CASB solutions. CloudCodes is one of the popular CASB services providers to secure all your data stored in the cloud. It helps the organization to track or monitor each and every unauthorized access to the data and notifies you time to time. It always provides innovative, reliable, and cost-effective cloud security solutions across the worldwide. It blocks all known and unknown intrusions and implements layer-wise security. Using this, one can be free about the cloud security because it assures the same.
