Uncover the Top Cloud Security Threats and Proven Defense Strategies

“U创营” is a cloud‑computing popular‑science course series designed for university students, offering video explanations, illustrated guides, and hands‑on practice to bridge the gap between theory and real‑world employment skills.

-1- Cloud Computing Security Risk Types

DDoS denial‑of‑service attacks : Attackers control massive numbers of machines to flood a target, exhausting bandwidth and resources so legitimate users cannot access services.

CC attacks : Attackers continuously send large volumes of packets to a server, depleting its resources until it crashes.

Web application attacks : Exploiting vulnerabilities in web apps to steal site information, user data, or gain control of the server.

Host intrusion attacks : Hackers target vulnerable or misconfigured cloud hosts to steal confidential data or conduct ransomware operations.

Data leakage attacks : Exploiting the window between vulnerability discovery and patching to infiltrate assets and obtain sensitive business data.

Website spoofing and hijacking : Threat actors impersonate HTTP sites, leading victims to phishing pages and causing sensitive information leakage.

Internal insider leaks : Operations personnel with backend privileges must enforce strict account, permission, and audit controls to prevent misuse.

-2- Cloud Platform Security Services

Cleaning and high‑defense services : Provide DDoS protection for elastic IPs and hosted servers, ensuring business continuity during attacks. When local bandwidth is insufficient, traffic is redirected to dedicated high‑defense facilities for scrubbing.

Host intrusion detection : Agents monitor servers for vulnerabilities, brute‑force attempts, successful logins, and backdoor installations, issuing alerts when malicious activity is detected.

Additional security services (details in course materials):

Vulnerability scanning

WAF (Web Application Firewall)

Certificate services

Database audit services

Bastion host (jump server)

Security situational awareness

-3- Cloud Computing Security Features

Cloud platforms aggregate massive resources, making them attractive targets for botnets, mining malware, and various cyber‑attacks such as web and host attacks, as well as large‑scale DDoS assaults.

Consequently, the security threats faced by cloud platforms far exceed those of traditional systems, requiring more sophisticated defense technologies and comprehensive risk‑analysis platforms that combine network, host, application, and data intelligence to reveal current threats and future trends.
