The requirement to purchase, manage, and maintain internal Secure Data Storage in Cloud Computing infrastructure is removed when data is stored on the cloud. Despite this ease, organizations continue to worry about losing control over cloud-based data, even though cloud storage security is often better than any on-premises defense.
This article serves as an introduction to data protection strategies used by cloud service providers and cloud storage security.
Continue reading to find out more about the various aspects of protecting cloud-based data and how to tell top-tier vendors from those with insufficient storage protection.
What is a Secure Data Storage in Cloud Computing?
A corporation can store data in the cloud as opposed to on-site storage thanks to the cloud storage service. With this arrangement, employees can have on-demand access to data from any device while having files stored conveniently on a third-party server.
These are typical use cases for cloud storage:
- Data archiving.
- Initial file archiving (most common in a hybrid and multi-cloud setup).
- Email archiving.
- DRaaS (Disaster Recovery as a Service) is a method of disaster recovery.
- Archived files.
- DevOps teams’ test and development environments spin up storage resources.
A corporation employing a public cloud must, in part, rely on the provider to keep data secure because cloud-stored data does not reside on an on-premises server.
The good news is that a top vendor’s data center employs a number of procedures to guarantee of Secure Data Storage in Cloud Computing. These actions frequently consist of:
- Encrypting data from end to end.
- Highly developed cybersecurity talents.
- Access control methods and protocols that are secure.
- Characteristics that ensure high availability.
- Putting data on servers spread across several different locations.
- High-end infrastructure and physical device security.
- Features for advanced cloud monitoring.
Is Cloud Storage Secure?
Your cloud storage will be safer than any on-prem infrastructure if you work with the proper provider. Although some cloud storage services are less secure than their providers want to admit, not all of them are the same.
Many capabilities and frameworks that a business cannot readily (or affordably) put on-prem are available from the proper provider. These abilities consist of:
- High-level redundancy: For disaster recovery scenarios, a provider-level data center has the best hardware and software redundancy.
- Dependable physical security: Compared to a typical in-office server room, a high-end data center maintains servers in a far more secure environment. Regular security precautions include armed guards, fingerprint locks, and round-the-clock facility surveillance.
- Multi-level security components: Top hardware and software-based firewalls are used by cloud providers to filter traffic going into and out of the cloud storage. Another typical approach is the employment of an intrusion detection system (IDS).
- Exemplary security examinations: To make sure that the storage security standards are up to speed with the most recent threats, cloud providers conduct frequent vulnerability assessments and penetration tests.
- Constant observation (CM): The security team is given real-time access to every server and cloud storage in the building thanks to CM.
Although the Secure Data Storage in Cloud Computing is probably more advanced than that of your on-premise equipment, the cloud adds complication to the data storage process. To ensure data security, your team must acquire new skills, modify security strategies, and implement new controls.
Operational Risks
Almost all cloud security breaches are the product of client-side operational errors. The most typical errors are as follows:
- Employees that use unapproved cloud storage platforms or services without the IT or security team’s knowledge.
- Transferring files to the incorrect user
- Accidentally erasing important data.
- Losing an encryption key as a result of bad key administration.
- Use passwords that are weak and simple to hack.
- Employees make use of insecure and unauthorized gadgets.
A business with a Bring Your Own Device (BYOD) culture faces an exceptionally high risk from the use of unlicensed devices. To maintain safe operations, the management must establish and strictly execute a BYOD policy.
Concern with Data Availability
Operational hazards might also arise from the perspective of the service provider. Typical problems include:
- Service interruptions are brought on by a staff member’s error or a server fault.
- A local catastrophe disrupts service, such as a fire, earthquake, or power outage.
- A cyberattack that is successful and targets the provider either directly or via another cloud user.
If something goes wrong with your storage provider, it will immediately affect how you can access your data. The team might not have access to cloud-based data until the vendor’s team fixes the problem, therefore you must wait for them to do so.
More Exposure to Data
Making ensuring no one outside the team can access the data is a big aspect of Secure Data Storage in Cloud Computing. When you rely on a partner to keep your information, the attack surface via which a bad actor can access your data is increased.
Even if you take all necessary measures to ensure that no one on the team leaks information. Your storage provider may unintentionally reveal your files and result in data leakage or open the door to an expensive attack.
Regulatory and Compliance Obligations
Cloud storage must satisfy all relevant criteria because compliance needs differ depending on how and where a corporation maintains data.
These requirements may specify how a service must:
- Data processing and storage.
- Manage who has access to files.
- Create storage segments.
- Remove the data.
- Safeguard data.
The cloud service must not only satisfy present needs but also be adaptable enough to let a company meet future needs and legal requirements.
Issues with Misconfiguration
Any mistake or flaw that puts cloud data at risk is referred to as a cloud misconfiguration. Misconfigurations are a typical issue since end users have limited access and control over data and processes.
Misconfigurations in cloud storage frequently come from:
- engineers without experience.
- IT blunders.
- inadequate resource and operation procedures.
An internal threat or an outside attacker who acquires access to the cloud due to a misconfiguration can frequently result in a data breach.
The Best Practices for Securing Cloud Storage
Secure Data Storage in Cloud Computing is a joint duty between the user and the service provider. If just one party has robust data protection, threats and attacks will result from the other side’s lack of security.
Cloud storage security should be approached in the following ways by both providers and users:
- For their platforms, the provider should put in place fundamental structures (authentication protocols, access control, high-end encryption, etc.).
- Clients should add additional safeguards to native frameworks to increase security and restrict access to cloud data.
Following is a look at the security best practices for cloud storage that suppliers and service users can use to guarantee data protection.
Encryption of Data
Cloud data must be encrypted by a cloud provider. In this method, only scrambled data will be accessible to an unauthorized user if a bad person or software accesses a file. Data can only be decoded with a decryption key.
Data should be encrypted both in transit and at rest by a provider:
- Cloud data that is not being used at the moment is protected by encryption at rest (AES 256-bit encryption is the most popular option).
- Data is protected while being transferred between two cloud or network points using encryption in transit (TLS/SSL 128-bit encryption is the most popular option).
Client-side encryption can help a business increase the security of its cloud storage. This tactic encrypts and decrypts data on the device of the intended user.
On the provider’s server, there are neither encryptions nor decryptions because the vendor does not hold any keys. The criminal won’t get their hands on your description key even if they hack into the provider’s server.
Using Two Factors to Authenticate (2FA)
Users that utilize two-factor authentication (2FA) must enter two different pieces of information when logging in. The employee must provide an additional credential in addition to their username and password, which can be:
- Biometric analysis (face or finger scans are the most common options).
- A one-time PIN is delivered to the user’s phone number or email.
- A physical token (typically a USB).
The second layer of security known as two-factor authentication makes it more difficult for an unauthorized person to gain access to cloud storage by using a stolen password (a common target of phishing attacks). Always choose a service that makes 2FA possible.
Create a Policy for Cloud Storage
A cloud storage policy makes sure that your staff is aware of how the business stores and manages its data on the cloud. This document should change as your company’s demands and the team’s utilization of cloud services change. A policy ought to state:
- A comprehensive list of all business goals connected to the cloud.
- Guidelines for the proper usage of cloud storage by employees.
- A rundown of recommendations for handling cloud data.
- Instructions on which cloud storage should receive which data.
- A list of all obligations related to compliance and regulation.
- All configuration requirements.
Your policy should encompass procedures for accessing, administering, integrating, and governing cloud usage inside your particular hybrid environment if you rely on hybrid cloud architecture.
Informing Staff About Cloud Storage Security
Protecting files in the cloud can be greatly improved by educating staff members about cloud storage security. Set up training sessions to acquaint staff with the key elements of your cloud storage strategy, such as:
- which files should be kept locally and which ones should be stored in the cloud.
- securing data sharing procedures.
- technologies and systems for cloud storage that are approved.
- the dangers associated with cloud storage and data sharing.
- applicable configuration guidelines.
- Rules for both internal and external access.
Monitoring of cloud storage
Potential dangers to cloud storage are found and eliminated with the use of ongoing change, access, and activity monitoring. The majority of storage services offer thorough cloud monitoring and notifications for:
- Fresh sign-ins
- Account movement.
- Data exchanges
- Delete a file.
- Strange and unusual activity.
You can implement your own cloud monitoring solution in addition to the warnings sent out by the provider team. By using an additional tool to Secure Data Storage in Cloud Computing, you can make sure that your team can see risks coming from your end and that you take a proactive approach to cloud storage security.
Secure Data Storage in Cloud Computing in the Future
A typical on-premises server is already much less secure than cloud storage, and predictions indicate that this security gap will continue to grow. The following noteworthy trends in cloud storage security are ones you should be aware of in the near future:
- AI Resources: Providers are progressively relying on AI to help safeguard cloud data. The initial stages of security analysis can be managed by an AI-powered tool, relieving staff workers of some of the workload.
- Multi-cloud storage is growing: As service providers look for solutions to reduce the threat of ransomware and enhance cloud disaster recovery, the practice of storing backup copies of data in additional clouds will become more and more common.
- Improved Performance: Along with increased security, cloud storage solutions will also improve in scalability and flexibility to compete with on-premises systems.
- lower costs: In order to increase cloud storage’s competitiveness, cloud providers will progressively concentrate on cost reduction. The abolition of prohibitive egress costs will probably be the first modification.
- Making a move for the edge: More cloud users will transfer their cloud storage closer to the edge of the network. Clients can set up and operate processes nearer to the customer base thanks to edge computing.
- Computing that is private: Confidential computing will be used by more vendors to further strengthen the security of cloud storage. This feature adds more in-use encryption to the at-rest and in-transit encryption to further protect data while it is being used.
Final Touch
Now you should be able to differentiate between cloud storage solutions that are adequately protected and those that aren’t. You can make use of cloud computing without increasing extra risk to your daily operations by selecting a dealer that delivers the majority (or, ideally, all) of the aforementioned capabilities.
