Are cloud storage’s being safe to store our personal data?
Cloud storage enables organizations, companies to store their data in third-party data centers through a cloud provider. Organizations are rapidly adopting the cloud, but there’s a concern: is data safe in the cloud?
All issues regarding cloud security are somewhat complex, but they fall into 2 broad categories:
- Security issues faced by the cloud providers (infrastructure-as-a-service via the cloud or organizations providing software-platform).
- Security issues faced by their customers (organizations or companies who host applications or store data on the cloud)
There are many concerns that cloud computing is inherently less secure than traditional approaches. The paranoia is due largely to the fact that the approach itself feels insecure, with your personal data stored on servers & systems you don’t own or control. However, cloud computing security offers a range of security options to make sure your data is encrypted & safely stored.
Cloud storage providers & enterprises share responsibility for cloud storage security. Cloud storage providers implement baseline protections for their platforms & the data they process, such as authentication, access control, & encryption. From there, most enterprises supplement these protections with added security measures of their own to bolster cloud data protection & tighten access to sensitive information in the cloud.
Cloud Storage Risks
Cloud security is tight, but it’s not infallible. Cybercriminals can get into those files or data, whether by guessing security questions or bypassing passwords.
But the bigger risk with cloud storage is cloud privacy. Even if data is not published or stolen, it can still be viewed. Governments can legally request information stored in the cloud, & it’s up to the cloud services provider to deny access. Tens of thousands of requests for user data are sent to Google, Microsoft, & other businesses each year by government agencies. A large percentage of the time, these companies hand over at least some kind of data, even if it’s not the content in full.
Cloud Security Controls
These controls are put in place to safeguard any weaknesses in the system & reduce the effect of an attack. While there are several types of controls behind a cloud security architecture, they can usually be found in one of the following categories.
Preventive controls strengthen the system against different incidents, generally by reducing if not actually eliminating vulnerabilities. For instance, Strong authentication of cloud users, makes it less likely that unauthorized users can access cloud systems, & more likely that cloud users are positively identified.
Detective controls are intended to detect & react appropriately to any incidents that occur. In the event of an attack, a detective control will signal the corrective controls or preventative to address the issue. System & network security monitoring, including intrusion detection & prevention arrangements, are typically employed to detect attacks on cloud systems & the supporting communications infrastructure.
Corrective controls reduce the consequences of any incident, normally by limiting the damage. They come into effect after or during an incident. Restoring system backups in order to rebuild a compromised system is an example of the corrective control.
There are many approaches enterprises take to ensure their data is secure in the cloud. Let’s take a look at them.
Cloud Data Encryption
To keep your data fully secure, the front line of defense for any cloud system is encryption. Encryption methods utilize the complex algorithms to conceal cloud-protected information. Might-be hackers would need the encryption key to decipher encrypted files. Although encrypted information is not 100 percent uncrackable, decryption requires a huge amount of computer processing power, forensic software, & a lot of time.
Data encryption in the cloud is the process of encoding or transforming data before it’s moved to cloud storage. The typically cloud service providers offer the encryption services ranging from an encrypted connection to limited encryption of sensitive data & provide encryption keys to decrypt the data as needed.
The best way you can protect your data encryption is so far. Encryption works as follows: You have a file which you want to move to a cloud, you use certain software with which you create a password for that file, you move that password-protected file to the cloud & no one is ever able to see the content of the file not knowing the password.
Data encryption is regarded as 1 of the most effective approaches to data security, database, scrambling the content of any system, or file in such a way that it’s impossible to decipher without a decryption key. By applying encryption & practicing secure encryption key management, companies can ensure that only authorized users have access to sensitive data. Even if lost, stolen, or accessed without authorization, encrypted data is unreadable & essentially meaningless without its key.
Some cloud services provide local encryption & decryption of your files in addition to storage & backup. This means that the service takes care of both encrypting your files on your own computer & storing them safely on the cloud.
Always Backup Your Data
Cloud storage is, by its nature, secure from various cyber-attacks & even natural disasters. It also offers a way to backup & restores data. Still, it’s smart to backup vital company’s information on in-house servers, just to be completely sure that crucial information is not lost in case of problems with the cloud provider.
Trust, but Verify
You have to validate the faith which you put in your cloud provider. Trust is essential because everyone must have access to your infrastructure if you are going to move & build quickly. But it’s essential that you also monitor & audit continuously so you can verify business-critical activity & manage risk effectively.
