Cloud Security 101: How To Secure Cloud Data


Cloud computing technology has become ubiquitous in today's digital world, enabling users to access storage, data backups, file sharing, social media, software, servers, streaming, conferencing, and more. A 2021 report shows that 33% of companies have over 50% of their workloads in the cloud, emphasizing the need for fundamental knowledge of cloud security.

When on the cloud, your data resides primarily on public servers, meaning that it can be prone to attacks. According to McAfee, one out of four companies using cloud services experiences data theft or a breach of some kind. And since almost 97% of companies worldwide are using cloud services in one way or another, it is important now more than ever to learn how to maintain the highest levels of cloud security from a user's standpoint. 

8 Cloud Security Tips to Secure Your Cloud Data

Two-factor authorization and strong passwords are the two most common ways to secure your data on the cloud. However, there are many other cloud security measures that organizations can put in place to protect sensitive data.

Use Stronger Passwords 

Choosing long and unique passwords with special characters, upper and lowercase letters, and using ‘pass phrases’ wherever possible will create a strong password. You can also use a password manager to develop unique passwords and safely store them. Don't forget to update your passwords regularly and don't use the same password across platforms. 

Embrace Multi-factor Authentication

Using multi-factor authentication (MFA) enables you to restrict unwelcomed visitors (mostly bad actors) from gaining access to your cloud services, even if they get their hands on your password. MFA adds another level to security by sending you a security code on your mobile device or email when someone tries to log in. There are even solutions that allow you to add biometric security for MFA.

Check and Update Privacy Settings

Configuring privacy settings should always be the first step after signing up for a cloud service. It is strongly recommended to evaluate and change default privacy settings as needed. Also, users should ensure that they don’t share their private information via the apps that connect to cloud services. Recheck the privacy or security settings and reconfigure after regular intervals to keep your information safe.

Audit Shared Folders

Cloud services are a good platform for storing, sharing, and working on files that contain sensitive information, but they may leave your data open to unauthorized access. Users are encouraged to add passwords and expiry dates to their shared files. 

You can also run a regular audit of all the active shares of your files. Then, choose to unshare shares (files) that no longer need to stay shared or available.

Choose Reliable Anti-Malware and Antivirus Offerings

It is important to have a strong antivirus program on all cloud-using devices. Solutions for malware protection also block suspicious URLs and downloads, keeping your cloud accounts safe. 

Go for a Cloud Provider with Strong Security Features

Choose cloud providers that utilize encryption and additional cloud security features to keep your data safe. While opting for a cloud service, evaluate the level of control that you get over your data.

Educate Your Employees

Users are often the weakest link in terms of cloud security. As a result, businesses should educate their staff regarding cloud security standards. Covering topics such as the risks of storing data in the cloud, the importance of having a strong password, the attack tactics that the threat actors use will help show your employees why cloud security is so important.

Backup Data Regularly

Data backups can pertain to both the cloud service provider and the organizations that use the cloud service. The cloud service provider should create data backups and store them across multiple data centers. This ensures easy data recovery when one of the servers goes offline. Companies, on the other hand, should also back up cloud-based files and choose a specific timeline to update them regularly. 


It is safe to assume that your data in the cloud is not 100% secure. It's best to take proactive measures to ensure the highest levels of cloud security. If however, you suspect your cloud account has been hacked, change your password and notify the service provider right away.
