Cloud Security is about securing data and applications in multi-cloud environments. It combines multiple tools to reduce risk exposure, including firewalls, CASBs, IAM, SIEM, DLP and more. It also includes services like network micro-segmentation, which limits users to specific parts of a network, and identity governance that helps enforce least privilege access and Zero Trust principles.

Rapid cloud adoption creates significant security risks, with overlapping vulnerabilities and high-risk exposure points across multiple platforms. Combined with misconfigurations, orphaned accounts, and unmanaged shadow assets, this creates a large attack surface for adversaries to exploit. It is critical to bring security in early in development, and implement automated risk assessment and remediation processes. This will help identify and resolve risks before they become a threat.

Lastly, robust monitoring and detection capabilities are required to reduce blind spots and ensure continuous visibility of critical applications. This includes continuous threat scanning and logging, vulnerability scans, red-teaming and digital twin exercises, and resilient disaster recovery processes. Ongoing employee training and awareness programs can help reduce human error that leads to breaches.

To protect data and apps from attacks, it is important to secure the perimeter with Next-Generation Firewalls and CASBs that provide a strict default Zero Trust policy until users supply credentials. This helps prevent many types of threats, including ransomware encrypting data, cryptojacking malware exploiting cloud resources for cryptocurrency mining and phishing attacks that attempt to steal login information. Similarly, data protection technologies, such as encryption and key management, secure transport of data in transit and at rest, and VPN anonymization help secure remote users’ ability to access and use the cloud.
