Starting our day from getting up to going to sleep, we upload our information at many places, like on Facebook, Instagram, Snap chat and various social media sites. Ever wondered where this information will be stored? Who can access our information? Is our data really safe? How to protect our information? Let’s get into details of all the questions…
Data as a whole is very huge, and storing data of every individual is a huge task. Data gets stored in clouds. The cloud is just a fancy way of describing a network of connected servers. A server is a computer or a device that provides functionality or services to other computers. There are two types of clouds: Public Clouds and Private Clouds.
HOW DATA GETS STORED IN A CLOUD?
How data gets stored in a cloud differs between the cloud vendors. When files get saved to the cloud, they can be accessed from any computer connected to that cloud’s network. The data is stored and accessed in the cloud via the Internet. The data storage in the cloud also known as cloud storage. It is actually a phenomenon of handing over your data to a storage service provider who stores it in their Datacenters.
A data centre is a centralized location, either physical or virtual, where networking and computing equipment is concentrated for the storage, management, and dissemination of data. Data is stored in the cloud either using different network distributed file systems or as local files on local drives in the cloud computing nodes.
Open stack a popular open source cloud stack. The most popular block storage solutions are Ceph and LVM which is a logical volume mapper for Linux. Objects are stored and replicated to protect against data loss. Objects stored in the cloud can be fetched via HTTP clients. Data which gets stored in the cloud is mostly stored in an encrypted form that would need to be cracked before an intruder could access the information.
WHY ARE PEOPLE CONCERNED WITH CLOUD COMPUTING?
As we aren’t storing our data in our personal hard disks, we are uploading our data into cloud storage which is supposed be guarded and managed by companies capable of storing a large amount of data. Including the likes of Google (Google Docs), Apple (iCloud), and Dropbox. Which will be saved a thousand miles away, so the safety of your information is in their hands now. Whether the data gets uploaded automatically (apps that sync to the cloud) or the users upload photos to social media, at the end it’s all there somewhere being logged and saved. So somehow the privacy of your data is not in your hands.
WHAT ARE THE RISKS OF CLOUD COMPUTING?
Cloud security will be obviously tight to secure your data, yet it is hackable. Cybercriminals can access your files by mere guessing of the security questions or bypassing the questions by hacking. There are many cloud hacking that took place, one of the worst is The Mirai Botnet (aka Dyn Attack) Back in October of 2016, the largest DDoS attack ever was launched on service provider Dyn using an IoT botnet. The biggest problem with cloud storage is privacy. Even if data is not completely stolen yet it can be viewed. Government officials can legally request to get access to the information, yet it depends upon the cloud service provider to accept the request. At large percentages, they provide at least some information if not complete information.
BENEFITS OF STORING DATA ON CLOUD
The data that you save in the cloud is comparatively more saver than having it on your own hard drive. Cloud servers are situated in warehouses away from the city which is heavily guarded. The data in the servers are encrypted, which makes hacking a tedious task for criminals. Whereas the virus on your computer can expose all of your personal data. It can also leave your files open to ransomware threats. So backing up your files onto the clouds is safer than having an enormous amount of data on your PC.
The cost-effectiveness and ease-of-access is another benefit of storing data on clouds. Using the cloud users can store a large amount of data, often for free. Against the number of external hard drives and USBs you’d have to purchase, and the difficulty accessing data once it’s been stored to multiple other devices, we can understand why cloud storage has become a popular option for businesses and consumers who store large amounts of data.
HOW TO PROTECT YOUR DATA?
Most of the cloud providers automatically encrypt data in transit by requiring SSL connections on any Web browser, but we don’t know whether this data is stored in encrypted containers. So it is better to encrypt your cloud data by using services like Cloud Information Protection | CipherCloud. If you have sensitive data you’d like to keep it away from prying eyes—probably the best way is to it store in a hard drive that remains disconnected from your home computer.
If you prefer saving your data on the cloud, we suggest you to follow these best practices to keep your data secure on the cloud:
- Use Strong passwords and Two-factor Authentication: Unique and randomized passwords should be used for storing data on the cloud. Use passwords with special characters and numbers. Don’t use the same password on any other platform. And protect your login even more with two-factor authentication.
- Back up your files in different cloud accounts: It’s never safe to put up all your important data in one place. Backup your data in different cloud accounts so it remains safe and secure.
- Practice smart browsing: Try avoiding accessing your data on public computers, if in case you’re accessing the cloud on a public computer, remember to log out and never save password info to your browser. Else you can delete your browsing history.
