2. 1

. Key Components

Governance: Policies, regulations, and compliance
requirements

Risk Management: Recognition, assessment, and
mitigation of risks

Identity & Access Management (IAM):
Authentication, authorization, and user
management

Data Security: Encryption, Data Loss Prevention
(DLP), and secure storage

Network Security: Firewall, VPNs, intrusion
detection/prevention

Incident Response: Monitoring, alerts, and
proactive responses to breaches

Security Operations: Continuous monitoring,
patch management, and auditing

3. 2. Core Principles

9 Confidentiality: Ensuring that data is accessible
solely to authorized individuals

9 Integrity: Protecting data from unauthorized
modification or deletion

9 Availability: Ensuring data and services are
available when needed

$

4. 3. Cloud Security Models

© Shared Responsibility Model: Clarifies which
security responsibilities belong to the cloud
provider and which belong to the customer

© Defense in Depth: Multi-layered security strategy
for maximum protection

9 Cloud Access Security Brokers (CASB): Enforce
security policies for data usage and access control
across cloud

© Zero Trust Security Model: No trust by default —
Verify every user and device before granting
access

9 Multi-Cloud Security Model: Uses services from
multiple providers (AWS, Google Cloud, Azure)

9 Hybrid Cloud Security Model: Need for unified
security across both environments (private and
public clouds)

$

5. 4. Best Practices

Data Encryption: Encrypt data at rest and in
transit

Strong Authentication: Use Multi-Factor
Authentication (MFA)

Access Control: Implement least privilege access
and Role-Based Access Control (RBAC)

Regular Audits: Conduct security audits and
compliance checks

Patch Management: Keep all systems up-to-date
with the latest security patches

Backup & Recovery: Ensure secure, frequent
backups and quick recovery mechanisms

6. 5. Threats & Vulnerabilities

9 Data Breaches: Unauthorized access to sensitive
data

© Insider Threats: Employees or trusted users
intentionally or unintentionally cause harm

9 DDoS Attacks: Distributed denial-of-service
attacks on cloud infrastructure

9 Misconfiguration: Security misconfigurations due
to improper settings or weak controls

© APIs Vulnerabilities: Security holes in cloud APIs
that could be exploited

$

7. 6. Compliance Standards

© GDPR: General Data Protection Regulation
ensuring data privacy and protection

9 HIPAA: Health Insurance Portability and
Accountability Act focusing on healthcare data

9 security
ISO 27001: International standard for

9 establishing and managing information security
systems

9 SOC 2: Service Organization Control for ensuring
secure cloud services

8. 7. Tools & Technologies

9 Firewalls: Cloud-native firewalls for traffic
monitoring and control

9 Encryption Solutions: Cloud-based encryption for
secure data storage and transmission

9 SIEM: Tools for real-time analysis and monitoring
Identity Management Solutions: Cloud IAM
solutions for user and device authentication

$

9. 8. Cloud Security Challenges

9 Complexity of Multi-Cloud Environments:
Managing security across different cloud
providers

© Evolving Threat Landscape: Constantly changing
cyber threats

9 Regulatory Compliance: Complying with both
local and global security regulations

9 Securing APIs: Managing security for integrations
between cloud apps
