Cloud Storage - Entriescloud

If cloud storage becomes infected with ransomware, it may result in significant damage. A plethora of cyberattacks on the cloud necessitates care by users.

For companies of all sizes, ransomware has been a chronic concern. Corporate entities must examine how ransomware may disrupt cloud-based systems.

Several cloud storage services exist, and various kinds of cloud storage are available. Also, various cloud storage solutions providers will provide many options for file, archive, and object storage.

For this discussion, generic cloud storage will be referred to as cloud storage. The best cloud security services can only help against certain forms of ransomware, and they are not universally implemented across all cloud service providers.

The epidemic known as Ransomware has been around for some time. Some early ransomware versions were simple. Most of the user’s hard disc was unaffected by a ransomware attack.

Back-end servers have become valuable to ransomware writers, who started to understand that critical data is often kept on back-end servers rather than simply on a hard drive. Such, in effect, led to ransomware evolving to encrypt network shares’ contents. A small percentage of today’s ransomware is even specifically created to target particular programs.

As we shall see, although cloud storage is essential, it is not a silver bullet on its own.

Here is how Ransomware Operates and how to keep yourself Protected

On cloud storage, the two critical components are how successful the ransomware assault was and how much data was recovered. The capabilities of ransomware are the first of these variables. Malicious ransomware is not always generated in the same way, just as unaltered cloud storage is not. Cloud storage ransomware is more effective on specific operating systems than others.

The second major issue is the degree of permission the user has been given by IT. Ransomware may compromise a user’s device as long as they have access to it. Ransomware attacks, which encrypt data on network-attached cloud storage, may potentially affect any data accessed by a user’s PC when it is mapped to the cloud. We may state this as an additional way of saying that the ransomware does not care if the data is located locally or remotely. When developing a new damaging technique, attackers make it as destructive as possible.

Companies can assist to prevent ransomware attacks from propagating to cloud storage in one of the most efficient methods possible. Everyone should have access to just the resources required to do their jobs. Companies should ensure that endpoint anti-malware protections are active, and if cloud-based anti-malware is available, then use it.

Malicious ransomware may infect cloud storage, like many other types of malware.
We should explore some of the typical methods of cloud storage in order to comprehend how ransomware may infect it.
It has been estimated that your cloud storage is susceptible to ransomware since it is synchronized with your local data storage.
You may work on your files locally if you have a Dropbox or OneDrive file sync and sharing solution installed. If you make any modifications to your documents, do they automatically get uploaded to the cloud?
When ransomware infects your PC, it will encrypt your data locally and share it with the cloud storage.
Also, in business, cloud storage gateways or other storage tiering solutions serve the same purpose. As its most probable that the ransomware will encrypt the local copy, this data will sync up to the cloud.
When pointers are present, the item will likely be recalled from the cloud and encrypted, and eventually synced back up to the cloud.

Is Versioning Helpful in the Protection of Your Data?

The concept behind versioning is that your existing data is unchanging. They are fixed in the present. Therefore any changes that are made will produce a new version.
In this regard, the encryption assault is, in fact, an advantage since it essentially means a new version of your infected data.
Even though many cloud storage solutions support versioning, you should double-check to see whether it is enabled since certain cloud storage providers disable versioning.
Cloud storage should be considered while recovering a network.
There must be versioning of cloud storage; otherwise, you must witness recovery scenarios where versioning helped.
After removing the ransomware, can you use the version history to return your local data to the latest known regular version? If you use cloud storage that has data recovery capabilities, your data will be recoverable. No one is entirely infallible.
When storing data in the cloud, can you distinguish and purge erroneous data and promote the most recent good copy to be the most current version?

Traditional Backup is Less helpful in Ransomware Protection than Cloud Backup

Except for new ransomware threat types, most malware evasion methods circumvent your virus scanner, which employs signature-based detection. Because of this, a comprehensive ransomware protection plan must go beyond obtaining the most recent virus definition and performing frequent data backups.

If your ransomware does not encrypt itself over those few days, weeks, or months, it is conceivable that your infection will go unnoticed. Often, but not always, ransomware affects just a part of an enterprise file system’s content profile. We may not encounter encrypted information as long as most data is outdated. In other words, having just conventional backups means you may recycle those copies before you discover that part of your data has been encrypted.

It is possible to configure a data-aware hybrid cloud storage system to mitigate the effects of ransomware. Before that, it determined whether unusual file access or file modification activity was happening, identified the user account, and let the administrator know with an alert. Furthermore, it allows efficient quarantine and recuperation while avoiding contamination of clean items.

With all the New Cyberattacks, new Security Strategies are Required

There is much interest in government agencies from both the private and public sectors to ensure vulnerabilities exist, and ransomware is a successful tactic for attackers. This means that cyberattacks will be there for a while.

Is cloud storage susceptible to ransomware? Absolutely. Preventing it from occurring means implementing tactics while preparing for the fact that it will happen and devising a plan to recover afterward.

Cloud storage costs can accumulate if you are not cautious rapidly. Moving data to the cloud may be a cost-effective method to reduce costs. Cloud storage may be much less costly than on-premises storage infrastructure, with expenses measured in cents per gigabyte rather than dollars. It may also be more dependable and more straightforward to maintain than on-premises storage equipment. That pennies-per-gigabyte, on the other hand, piles up over time. If you are not cautious about keeping your cloud storage expenses under control, you may wind up with a total storage charge that is much more than you anticipated.

In light of this issue, here is a summary of recommended practices for reducing cloud storage expenses while maintaining storage reliability and performance standards.

First, Choose An Inexpensive Online Data Storage Provider

The most efficient way to minimize your cloud storage costs is to guarantee that you pick the cheapest storage platform from the start of your storage journey.

Note that other cloud storage providers may not supply all of the capabilities you need in your cloud storage solution. They usually provide object storage comparable to services such as AWS S3 and Azure Blob Storage, among others. The lack of block storage and a limited selection of databases that you can find on a Big Three cloud platform, as well as other types of cloud services such as virtual machines.

The bottom line: If you need object storage, be careful to compare the features and prices offered by smaller-name cloud providers before deciding. In certain instances, these providers may be able to offer the storage you need at a much cheaper cost than AWS, Azure, or GCP, but this will depend on your requirements and use cases.

Select the most Appropriate Storage Service

If you decide to store data in a cloud that provides various storage options, be sure to choose the most cost-effective storage option for your requirements from the available options.

Object storage is a cost-effective and straightforward way to store data on the cloud. Depending on what you intend to do with the data, a different kind of storage may be less expensive in the long term. Sometimes it is preferable to keep data in a database, which can be structured to save your app time (and money) in importing and processing it. Object storage’s lack of flexibility may make data analysis more expensive and time-consuming.

Make use of Storage Types or Tiers for your Advantage

Object storage services are offered in a variety of “classes” (as defined by AWS and Google Cloud Platform) or “tiers” (as defined by Microsoft Azure) on various public cloud platforms. The costliest storage class or tier is the standard storage class or tier. Choosing a lower-cost storage tier allows you to save money on storage costs. Essentially, the idea is the same as that used in on-premises storage tiering methods.

The trade-off is that lower-cost storage choices often provide lower levels of performance than higher-cost storage options. The data on these tiers is not immediately accessible; it may take a few minutes to many hours to view the information. If you use the data regularly, you may also have to pay additional costs to access it.

Lower cloud storage costs tiers or classes, on the other hand, may or may not be an intelligent method to reduce your cloud storage expenditures, depending on what you want to do with your data. Archival data that you do not anticipate being accessed frequently makes an excellent choice for low-cost storage tiers. Data that your apps need to read or write regularly is not protected against unauthorized access.

Implement Data Lifecycle Policies in the Cloud

When do you need your data stored in a typical storage class on certain occasions but not on others? It is at this point that data lifecycle rules come into play. Creating rules that automatically migrate data from one storage class or tier to another is possible on most large public clouds. These rules help you save money by ensuring that data is not kept in a higher-cost class for longer than necessary.

It is possible to reduce your cloud storage costs by using lifecycle rules. For instance, log data you initially need to retain available in case you need to reference it for troubleshooting reasons may be reduced using lifecycle policies. You may automatically transfer logs to a lower-cost tier as they get older and less likely to be required by using a lifecycle strategy to manage the process.

Be Cautious when it Comes to Data Dependability

Every company/organization’s primary concern is to protect data from temporary or permanent loss. It can be one of the reasons for data migration to the cloud: You are correct that the cloud will outperform your on-site infrastructure.

A balance between data dependability and cost has to be found. Most cloud services have excellent standard availability levels; for example, Amazon guarantees availability for “119s” after uploading data stored in its S3 services. In general, the default strength in S3 should be sufficient for most clients as long as they are ready to tolerate a 0.000000001% risk of data loss.

You may need even greater reliability. So you may want to explore replicating your data across cloud availability zones or perhaps keeping redundant copies elsewhere. This increases the chances of your data being safe and accessible in the event of a cloud infrastructure failure. However, it will substantially raise your storage costs.

Do not Keep Any More Data than is Necessary

Finally, you may reduce cloud storage costs by ensuring that only data is stored in the cloud when necessary.

However, given how simple it is to transfer data to the cloud—and how difficult it is to maintain track of it after it has been uploaded—you may unintentionally wind up with bloated cloud environments packed with data that you no longer need or that should be relocated back on-premises to avoid data loss.

To avoid such threats, ensure you understand your cloud storage strategy’s architecture and where your data is kept. Using most cloud storage services’ tagging features, you may also tag data to make it easier to find. For example, if you must keep some data for a certain period due to regulatory constraints, you may tag the data and delete it after the specified retention period.

Cloud storage may be inexpensive, but only if you approach it in an educated manner. For maximum cost savings, ensure that you choose the right cloud platform, cloud storage solutions providers, and data management methods before beginning your cloud storage migration project.
