Cloud security refers to the technologies, policies, controls, and services that protect cloud data, applications, and infrastructure from threats. Human error is one of the top reasons for data breaches in the cloud, as administrators forget to turn on basic security controls. Whether it is Amazon Web Services, Microsoft Azure, or Google Cloud Platform, keep these rules in mind to secure your cloud workloads.
A Definition Of Cloud Storage SecurityCloud-based internet security is an outsourced solution for storing data. Instead of saving data onto local hard drives, users store data on Internet-connected servers. Data Centers manage these servers to keep the data safe and secure to access. Enterprises turn to cloud storage solutions to solve a variety of problems. Small businesses use the cloud to cut costs. IT specialists turn to the cloud as the best way to store sensitive data. Any time you access files stored remotely, you are accessing a cloud. Email is a prime example. Most email users don’t bother saving emails to their devices because those devices are connected to the Internet. Learn about cloud storage security and how to take steps to secure your cloud servers.
Types of Cloud: Public, Private, Hybrid
There are three types of cloud solutions.
Each of these offers a unique combination of advantages and drawbacks: Public Cloud: These services offer accessibility and security. This security is best suited for unstructured data, like files in folders. Most users don’t get a great deal of customized attention from public cloud providers. This option is affordable. Private Cloud: Private cloud hosting services are on-premises solutions. Users assert unlimited control over the system. Private cloud storage is more expensive. This is because the owner manages and maintains the physical hardware. Hybrid Cloud: Many companies choose to keep high-volume files on the public cloud and sensitive data on a private cloud. This hybrid approach strikes a balance between affordability and customization. How Secure is Cloud Storage? All files stored on secure cloud servers benefit from an enhanced level of security. The security credential most users are familiar with is the password. Cloud storage security vendors secure data using other means as well.
Some of these include:
- Advanced Firewalls: All Firewall types inspect traveling data packets. Simple ones only examine the source and destination data. Advanced ones verify packet content integrity. These programs then map packet contents to known security threats.
- Intrusion Detection: Online secure storage can serve many users at the same time. Successful cloud security systems rely on identifying when someone tries to break into the system. Multiple levels of detection ensure cloud vendors can even stop intruders who break past the network’s initial defenses.
- Event Logging: Event logs help security analysts understand threats. These logs record network actions. Analysts use this data to build a narrative concerning network events. This helps them predict and prevent security breaches.
- Internal Firewalls: Not all accounts should have complete access to data stored in the cloud. Limiting secure cloud access through internal firewalls boosts security. This ensures that even a compromised account cannot gain full access.
- Encryption: Encryption keeps data safe from unauthorized users. If an attacker steals an encrypted file, access is denied without finding a secret key. The data is worthless to anyone who does not have the key.
Physical Security: Cloud data centers are highly secure. Certified data centers have 24-hour monitoring, fingerprint locks, and armed guards. These places are more secure than almost all on-site data centers. Different cloud vendors use different approaches for each of these factors. For instance, some cloud storage systems keep user encryption keys from their users. Others give the encryption keys to their users. Best-in-class cloud infrastructure relies on giving users the ideal balance between access and security. If you trust users with their own keys, users may accidentally give the keys to an unauthorized person. There are many different ways to structure a cloud security framework. The user must follow guidelines laid out in the cloud security policy when using the cloud. For a security system to be complete, users must adhere to a security awareness training program. Even the most advanced security system cannot compensate for negligent users. ...from https://phoenixnap.com/blog/cloud-storage-security
