What is Cloud Security?
Cloud Security is a cybersecurity practice that encompasses policies, procedures, and technologies to protect data and applications hosted in or accessed through the cloud. It includes firewalls, network security solutions, and endpoint protection systems.
The interconnected nature of the cloud promotes collaboration, but it also exposes vulnerabilities and risks such as data breaches and leaks. For example, a server cloud misconfiguration exposed the personal information of 100 million Capital One customers in 2019. Another notorious incident involved the 2021 ransomware attack that disrupted operations at the JBS meat processor, impacting global supply chains. These incidents highlight the importance of deploying robust and resilient cyber defenses, including multi-factor authentication, encryption tools for data in transit or at rest, and dynamic network segmentation to minimize attack surface.
Using the right set of tools is key for ensuring cloud security. Look for SIEM (security information and event management) solutions that work across multiple vendors, pentest tools such as Burp Suite or CIS Hardened AMIs (AKA Golden Images), and Azure security solutions like Active Directory with a granular view into resource access.
