Cloud-based computing is quickly establishing itself as the future of data storage and computing. The current era is dominated by digital transformation, and the cloud has become the cornerstone of modern business operations. Cloud-based storage offers several advantages: you can sync several devices simultaneously, and all your employees can access relevant data.
However, with this shift comes the need to prioritize security in the cloud environment. Cloud-based storage is particularly vulnerable to hackers and malware, as any malware that makes its way to the cloud can transfer to all the devices connected with the cloud. Here are some practices that can fortify cloud infrastructure against threats and vulnerabilities:
- Using a Cloud Access Security Broker
A Cloud Access Security Broker, or CASB, is a security solution that gives organizations visibility and control over cloud applications and services within their environment. It tells the organization which cloud applications are being accessed by whom. CASBs offer data security features like data encryption, data loss prevention (DLP), and access controls to ensure that only authorized users can access data on the cloud.
A CASB solution can also identify and manage shadow IT usage or unauthorized cloud applications within the organization. Through its compliance reporting, audit logging, and policy enforcement features, CASBs also help maintain compliance with regulatory requirements and industry standards regarding data privacy.
- Implementing Strong Authentication Mechanisms
Authentication is the frontline defense against unauthorized access to sensitive data and resources. A robust authentication mechanism can secure your cloud solution. Consider utilizing multi-factor authentication (MFA) protocols to bolster traditional password-based systems.
If you use OneDrive as your cloud storage, mandate Microsoft Authenticator for your organization’s accounts. You can also consider other authentication mechanisms like biometric verification, token-based authentication, and adaptive authentication to reduce the risk of unauthorized entry.

- Encrypt Data Both in Transit and at Rest
Data encryption is paramount in safeguarding information from interception and unauthorized access. Consider employing robust encryption algorithms to secure data. When using encryption algorithms, ensure that the data is encrypted not only in the cloud but also in transit between the servers and devices. Similarly, data should be encrypted off-cloud in physical storage devices as well. Remember to manage encryption keys securely and enforce regular rotation to enhance security.
- Regularly Update and Patch Systems
Software vulnerabilities are a common entry point for cyberattacks. Stay vigilant by promptly applying security patches and updates released by cloud service providers and software vendors.
Automated patch management systems can streamline this process, ensuring your cloud infrastructure remains fortified against known vulnerabilities. If you use an antivirus system for cloud storage, ensure its database is regularly updated with the latest repository of malware.
- Monitor and Log Activities
Comprehensive monitoring and logging mechanisms provide visibility into your cloud environment, enabling real-time threat detection and incident response. Implement robust logging practices to capture and analyze user activities, system events, and network traffic. Leverage cloud-native monitoring tools, security information, and event management solutions to promptly identify anomalous behavior and potential security incidents.
Endnote
As the digital transformation continues, most businesses have shifted to cloud-based storage. While cloud storage offers several benefits, there is a risk to data security. Several practices can alleviate data security concerns in cloud systems, such as using CASBs and robust authentication protocols like MFA. Data encryption, both in transit and at rest, can protect your cloud data, too. Regularly updating and patching software and monitoring and logging activities can alleviate significant cybersecurity concerns.
