What is Cloud storage security and why is it important?

Cloud Encryption: Best practice for Cloud Security

Cloud Encryption is a critical component of Cloud Computing Security Best Practices since it ensures that your cloud data is secured at rest and in transit. It is a solution offered by cloud storage companies that encrypts and stores a customer’s data in the cloud. Cloud encryption is almost identical to on-premises encryption. Still, for one important distinction: the cloud customer must learn about the provider’s encryption and key management policies and procedures. The cloud encryption capabilities of the service provider must be consistent with the sensitivity of the stored data. In this article we will discuss how it works, its importance, challenges, benefits, and how Alibaba Cloud offers high-security infrastructure capabilities, allowing users to store and utilize data securely on a trusted cloud platform.

Cloud encryption’s advantages

Cloud encryption acts as proactive protection against data breaches and assaults, allowing businesses and their users to use the advantages of cloud collaboration services without jeopardizing data security. It can secure data from end-to-end throughout the transit to and from the cloud and against unwanted access. Additionally, it complies with a large number of consumer and governmental data security standards.

Cloud encryption solutions protect data during transmission to and from cloud-based applications and storage and between users in several locations. Additionally, these technologies encrypt data stored on cloud-based storage devices. These protections prevent unauthorized users from accessing data during its transfer to and from the cloud. Amazon Web Services (AWS), Dropbox, Microsoft Azure, and Google Cloud all provide cloud services that encrypt data at rest.

Difficulties with cloud encryption

While the security benefits of cloud encryption exceed the drawbacks, administrators should be aware of typical issues. Historically, performance and integration issues have prevented many organizations from adopting encryption as a regular practice since the users who need quick access see encryption as excessively complex or inconvenient for users. While modern systems are faster and simpler to use, it is critical to try any platform to verify that integration and usability satisfy needs. Due to the resource-intensive nature of the encryption process, which adds time and money to daily operations, it’s also critical to monitor access times and resource consumption levels.

The loss of encryption keys is a serious issue since it renders all encrypted data unusable, and poor key management may risk essential data. However, the most significant issue is ensuring that any cloud encryption services are in use correctly.

Best Cloud Encryption Approaches

To guarantee compliance issues with the company’s security strategy, security teams should sketch out the security needs for any data that travels to and from the cloud. This will assist in identifying cloud service providers that provide adequate encryption choices and services. Security teams must decide on the following:

  • Which data must be encrypted based on its data categorization and compliance requirements
  • When encryption is required — in transit, at rest, and during use
  • Who should be in possession of the encryption keys — the cloud service provider or the enterprise?

Continous Encryption

All data in transit must encrypt anytime it leaves the internal network. It will always travel through an unknown number of third parties, and it should secure sensitive data even while sent inside. While web browsers and File Transfer Protocol (FTP) software safely handle natively in transit, all connections must utilize a secure protocol. While virtual private networks (VPNs) and IP security (IPsec) are other methods for protecting data in transit, they provide an additional degree of complexity. Cloud access security broker (CASB) solutions provide security administrators with a centralized interface for controlling and managing cloud resources and ensuring users adhere to the organization’s security rules.

Memory and Backup

You should always encrypt and back up critical data locally before transferring it to the cloud. This guarantees that data is accessible and safe in the cloud. Numerous vendors provide robust disc encryption at both the client and network levels. We require Complete disc and memory encryption to protect sensitive data in use, however, this may prevent specific programs from processing the data; thus, tight access controls and limited access to particular data sets are critical alternatives.

Encryption Key

Extensive encryption key management is essential, from key registration to enable complete lifecycle monitoring. The keys should be kept separately from the encrypted data, with off-site backups and frequent auditing. Additionally, administrators should enable multifactor authentication (MFA) for the master and recovery keys. While some cloud encryption companies offer to handle encryption keys, an appealing feature for businesses lacking in-house expertise and resources, regulatory compliance requirements may compel some to retain and manage keys internally.

Cloud Security in Alibaba Cloud

Alibaba Cloud offers high-security infrastructure capabilities, allowing them to store and utilize data securely on a trusted cloud platform. Alibaba Cloud architecture protects and scans hardware and firmware, and enables a TPM2.0-compliant computing environment. Moreover, it provides hardware encryption (HSM) and chip-level encryption computing capabilities at the cloud platform layer.

At the cloud product layer, data security integrates with the security aspects of cloud products. It includes end-to-end data encryption, backup, and verification. Among them, end-to-end data encryption is the best data encryption practice.

End-to-end data encryption enables the data encryption on transmission connections (i.e., data in transit), compute nodes (i.e., data in use), and storage nodes (i.e., data-at-rest). Specifically, transmission encryption depends heavily on SSL/TLS encryption and protects data using AES256 encryption.

Moreover, it supports AES256 data-at-rest encryption in different products. It also supports Bring Your Own Key (BYOK) through Key Management Service (KMS). Alibaba Cloud, in conjunction with KMS, may offer customers end-to-end data encryption security.

A data encryption process uses globally recognized/standardized encryption methods to generate the ciphertext from plain text data. Proper security protection and management of keys are critical components of the encryption process. If one retains control of the key, one has control of the encryption processes as a whole.

Conclusion

While cloud encryption has a number of disadvantages and difficulties, it is required by standards, laws, and organizational security needs. Security experts would agree that cloud encryption is a critical component of data security. Additionally, cloud service providers provide a variety of encryption solutions to accommodate a variety of budgets and data security requirements.

To enjoy the advantages of cloud encryption, an organization should spend time understanding its data protection requirements and studying the most appropriate and effective encryption services offered by various suppliers in order to avoid putting itself in danger. In this article, we have also discussed how Alibaba Cloud offers high-security infrastructure capabilities, allowing them to store and utilize data securely on a trusted cloud platform.

Cloud Storage: Important Facts

Cloud computing model known as Cloud Storage is a globally distributed, secure, and scalable object storage system for immutable data types such as pictures, text, video files, and other file formats. Each item identifies by a unique identifier, metadata, characteristics, and the data itself. The metadata may include various types of information, such as the file’s security classification, the programs that can use it, and essential details. The unique identifier, knowledge, and characteristics make object storage an attractive storage option for a wide range of applications, from web serving to data analytics.

Numerous cloud computing storage providers including Nihao Cloud provide various services that can be useful to the customer to a greater or lesser extent. This post will not be about our service at NiHao Cloud and I don’t have a favorite in this category since they’re all unique in their ways. Nevertheless, each cloud computing service has a few common words, which I have discussed below.

Best Cloud Storage Providers

Cloud Storage Services: 

While hosting firms often provide various services, the primary one is data storage on the “cloud.” we will discuss some of the terms with respect to storage below:

Synchronization

Synchronization of files implies that whatever you save to the cloud on one device will be available on all of your other devices. Whether it’s movies, pictures, documents, or music, the cloud can save everything. Most hosting providers have already adopted this since it is the entire core of cloud computing storage. At work, upload your data and then access it when you get home. Additionally, they offer a desktop version that resembles an illusory drive on which you may save your data. It’s much more convenient to utilize the desktop version than repeated login into your account on your browser. It looked like such an intriguing method to save your info. 

Backup

While cloud storage needs you to store your data online actively, the backup function provides an alternative. It enables the smooth transfer of your data to the cloud for safekeeping. This is very useful if your hard disc fails or you lose your smartphone/notebook. Another method to accomplish this is to download backup apps to your mobile device, often already offered by cloud computing storage providers. You may select to save your pictures in your backup folder, erasing the photos stored on your phone in the process.

Numerous cloud storage providers do not even have a backup option. On the other hand, there are also plenty of them that are only for file backup.

File sharing:

The feature is self-explanatory. Are you collaborating with your mates on a class project or a task? Utilize numerous methods for sharing your files. You may either connect your folders or generate download links that you can share with your friends. This is probably one of the things that your physical storage lacks. To be quite candid, I can’t imagine functioning without cloud computing storage. Not to mention the hundreds of millions of individual users, but we’ll get to that later.

Versioning of objects:

Cloud storage enables this functionality. Once enabled, a history of file changes will maintain for all objects. This allows you to recover previous versions of your files or even recover erased data. Each item is endowed with specific characteristics that aid in its recognition. When you remove an item enabled for this feature, a duplicate of the object is immediately stored with attributes that help identify it. I suppose I should say that not all service providers provide this option in their free plans. Additionally, some do not include it in their payment plans.

File retrieval:

It’s comparable to object versioning. Some/most cloud services provided by default or via the installation of different add-ons can recover lost data. Some have a temporal restriction on how long data may be recovered, while others keep it forever. They are often kept in a subdirectory called “trash” or “deleted files.” If you are unable to locate it, it is most likely not included in your current plan. You may contact me, and I will gladly assist you by studying for you or just giving the knowledge direct from my brain. Additionally, you may consult my reviews section for additional information. Here is an example.

Third-party applications:

The box is an example of this. It integrates third-party applications such as Microsoft Word, PowerPoint, Google Documents, and Google Sheets within the software itself. It’s one factor to consider while choosing a cloud storage provider. Few cloud services integrate third-party apps.

Cloud Storage Service Types

Not all cloud storage users have the exact needs or requirements. As a result, many cloud storage providers provide a variety of distinct cloud storage solutions.

Personal

Personal Cloud Storage While most cloud storage services let you access their remote servers, you may also set up your server at home to establish your cloud storage.

Western Digital My Cloud, for example, enables you to create a private server accessible only to you. There are a variety of reasons why this may be necessary. It’s ideal for streaming media — such as music and movies — inside your house since you can depend on your home network’s better speeds than you would receive streaming from a server over the internet.

It also means you won’t have to worry about your cloud vendor sniffing around and analyzing your files if your media material comes from less-than-trustworthy sources.

Private cloud storage, on the other hand, is essentially business-specific cloud storage. This is the process through which a company establishes its storage servers in-house.

There are various reasons why a company may want to create its private cloud storage, but one of the most compelling is that some companies are legally obliged to keep customer data on-premises.

Public

This is often understood when the term “cloud storage” is used. Google Drive and pCloud, for example, have whole racks of servers devoted to serving the public in data centers, enabling customers to keep their files in the cloud.

While these providers primarily serve the consumer data storage market, several cloud storage providers also provide business-oriented solutions for off-site data storage. In addition, check out our roundup of the top corporate cloud storage services.

Hybrid Storage

Combine the speed and security of private cloud storage with the simplicity and adaptability of public cloud storage, and you’ve found hybrid cloud storage, a novel approach to online file storage.

Hybrid cloud storage also enables you to mix your on-premises storage with that provided by a public cloud storage provider. This allows you to choose to store data locally and files remotely in the cloud.

This combines the best of both worlds and maybe the optimal option for a wide variety of companies. As explained in our previous Microsoft Azure review, services like Microsoft Azure enable you to manage your hybrid cloud storage.
