Cybersecurity within cloud computing and hosting primarily aims to protect data, applications, and infrastructure from unauthorized access, damage, or disruption. This typically involves multiple layers of defense to address diverse threats such as malware, phishing, insider risks, and distributed denial-of-service (DDoS) attacks. Implementation of cybersecurity measures in these domains often follows established standards and best practices specific to cloud environments.

Identity and access management (IAM) systems help ensure that only authorized users can interact with cloud or hosting resources. These systems may include features such as multi-factor authentication and role-based access controls to decrease the likelihood of credential compromise. Monitoring tools continually analyze logs and network traffic for irregular patterns potentially indicating a security incident.
Encryption methods are usually applied both during data transmission and while data is stored, reducing the chances that intercepted information can be read or manipulated. Security policies related to patch management and vulnerability assessment contribute to identifying and remedying weaknesses. Additionally, security information and event management (SIEM) systems can aggregate and analyze security alerts from across cloud and hosting components to aid in threat detection.
Collaboration between cloud providers and hosting services often extends to shared responsibility models, whereby certain security obligations fall on the provider and others on the user organization. This division can vary depending on service type such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). Understanding these responsibilities is important for establishing effective cybersecurity controls within combined cloud-hosting environments.
