Cybersecurity protects identities, data, applications, infrastructure, and networks against unauthorized access, disruption, and misuse. It addresses a persistent operational problem: digital services remain exposed to changing threats, including ransomware, fraud, theft, and public data exposure. section 1.0 section 1.9
Treat cybersecurity as an infinite game rather than a one-time contest with a final winner. Attackers, tactics, technologies, and cloud environments continually change, so security requires ongoing learning, assessment, and adjustment instead of reliance on a single solution. section 1.1 section 11.5
Common cloud security problems include:
- Misconfigured workloads, exposed virtual machines, leaked credentials, and unencrypted secrets can create direct paths to unauthorized access. section 1.1
- Ransomware, brute-force attacks, supply-chain attacks, zero-day vulnerabilities, data theft, insider threats, and denial-of-service attacks form part of the wider threat landscape. section 1.1
- The shared responsibility model clarifies which security responsibilities belong to the cloud provider and which remain with the organization. section 1.9
- Defense in depth combines multiple security controls and services so that one failed control does not determine the outcome. section 1.9
Rushed cloud migration
A rushed move from on-premises systems to the public cloud can leave virtual machines exposed to the internet, credentials available to attackers, and secrets visible in source-code repositories. Improving the resulting security posture requires iterative assessment and multiple Azure security services rather than a single corrective measure. section 1.1 section 1.9
