Cloud security is the protection of data stored online from theft, leakage and deletion.
Methods of providing cloud security include firewalls, penetration testing, obfuscation, tokenization, virtual private networks (VPN), and avoiding public internet connections.
Major threats to cloud security include data breaches, data loss, account hijacking, service traffic hijacking, insecure application program interfaces (APIs), poor choice of cloud storage providers, and shared technology that can compromise cloud security. Distributed denial of service (DDoS) attacks are another threat to cloud security.
These attacks shut down a service by overwhelming it with data so that users cannot access their accounts, such as bank accounts or email accounts.
