Cloud Security protects apps, workloads and cloud data from threats in the cloud. It also provides visibility into cloud usage and helps prevent data loss. It leverages advanced analytics to identify and respond to anomalous behavior in the cloud and enables clients to proactively detect and block attacks. It can be used to complement other security solutions, such as identity and access management (IAM), firewalls, cloud access control brokers (CASB), and enterprise threat protection (ETP) tools.

Secure cloud use starts with a strong password policy that includes a mix of letters, numbers and special characters to make it hard for hackers to guess or brute-force. Use multi-factor authentication (MFA) to stop unauthorized logins and ensure users are who they say they are. Avoid using public Wi-Fi, especially if you are accessing cloud data that is sensitive or private. If you must, use a VPN.

When it comes to cloud service providers, the most important part of secure use is choosing one that takes security seriously. Enterprises can insist on a privately hosted private cloud, but small to midsize businesses must deal with public services like storage and web applications. In these cases, it’s vital that the provider can keep its servers secure, particularly when dealing with multitenant data.

Cloud security solutions include virtualized firewalls, cloud proxies and a variety of encryption tools to keep data at the edge of the network. They must also include capabilities that help companies monitor and manage the security of their own systems in the cloud, such as SIEM and XDR solutions.
