Tutorial / Cram Notes
Identity and Access Management systems are the cornerstone of security for both cloud and on-premises infrastructures. They ensure that only authenticated and authorized users can access resources within the organization. Examples of IAM solutions include Azure Active Directory for the cloud and Active Directory for on-premises environments.
Cloud and On-Premises Key Components to be Protected:
| Cloud Components | On-Premises Components |
|---|---|
| User identities | User credentials |
| Managed identities | Managed service accounts |
| Access control policies | Group and user permissions |
| Multi-Factor Authentication (MFA) | MFA solutions |
Data Protection:
Both cloud and on-premises solutions need robust measures to protect data, including encryption in transit and at rest. In the cloud, services like Azure Information Protection can classify and protect documents and emails. On-premises, solutions like BitLocker can provide encryption for data stored on physical drives.
Protective Data Measures Comparison:
| Cloud Data Protection | On-Premises Data Protection |
|---|---|
| Azure Information Protection | Windows Information Protection |
| Azure Backup | On-premises backup solutions |
| Transparent Data Encryption | Database encryption methods |
Network Security:
On the network level, cloud resources are protected by network security groups, firewalls such as Azure Firewall, and Virtual Network configurations that control inbound and outbound traffic. On-premises networks rely on firewall appliances, intrusion detection/prevention systems, and segmented network zones.
Network Security Measures:
| Cloud Network Security | On-Premises Network Security |
|---|---|
| Azure Firewall | Network Firewall Appliances |
| Virtual Networks (VNets) | Virtual LANs (VLANs) |
| Network Security Groups (NSGs) | Intrusion Detection Systems (IDS) |
Endpoint Security:
End-to-end protection for devices that access the organization’s resources is crucial. For cloud services, Microsoft Defender for Endpoint can monitor and respond to threats. On-premises, traditional antivirus and anti-malware solutions can provide similar protection.
Endpoint Security Solutions:
| Cloud Endpoints | On-Premises Endpoints |
|---|---|
| Microsoft Defender for Endpoint | Antivirus software |
| Microsoft Intune | Group Policy settings |
| Azure Security Center | Security Information and Event Management (SIEM) solutions |
Disaster Recovery and Business Continuity:
Having a plan for when things go wrong is essential. The cloud offers services like Azure Site Recovery for replicating workloads and enabling quick failover. On-premises disaster recovery might involve maintaining secondary data centers or backup sites.
Disaster Recovery Strategies:
| Cloud Disaster Recovery | On-Premises Disaster Recovery |
|---|---|
| Azure Site Recovery | Secondary Data Centers |
| Azure Backup | Offsite Backup Storage |
| Geo-redundant storage (GRS) | Backup and Recovery Software |
Application Security:
Applications, whether hosted in the cloud or on-premises, must be secure by design. Cloud applications benefit from tools like Azure App Service’s built-in security features, while on-premises applications require application firewalls and regular security assessments.
Application Security Features:
| Cloud Applications | On-Premises Applications |
|---|---|
| Azure App Service Security | Web Application Firewalls (WAF) |
| Azure SQL Database Threat Detection | Database Activity Monitoring (DAM) |
Monitoring and Logging:
Continual monitoring, logging, and analysis of security-related events are necessary to detect and respond to threats in real time. Azure offers services such as Azure Monitor and Azure Security Center for the cloud, while on-premises solutions may include SIEM systems like Splunk or IBM QRadar.
Monitoring and Logging Services:
| Cloud Monitoring | On-Premises Monitoring |
|---|---|
| Azure Monitor | SIEM Solutions (e.g., Splunk) |
| Azure Security Center | Network Monitoring Tools |
Compliance and Regulatory Requirements:
Organizations must adhere to legal and regulatory standards, such as GDPR or HIPAA. Cloud services often offer compliance frameworks and certifications, while on-premises infrastructures require the organization to ensure compliance through policies and audits.
Compliance Frameworks:
| Cloud Compliance | On-Premises Compliance |
|---|---|
| Microsoft Compliance Manager | Internal Audit Procedures |
| Azure Trust Center | Compliance Documentation |
To fully embrace the protection of cloud and on-premises infrastructure, deciding on the correct mix of these components while considering their specific industry standards and regulatory requirements is pivotal for every organization’s security posture. With Microsoft 365’s suite of applications, both cloud and on-premises environments can achieve a high standard of security and compliance, essential for today’s operational needs.
Practice Test with Explanation
True or False: Data stored on physical servers on premises is less vulnerable to security breaches than data stored in the cloud.

Some of the benefits of using Azure AD Conditional Access include increased security, more granular access control, improved user productivity, and the ability to monitor and audit access to resources.
What is the difference between an identity policy and an access policy?
An identity policy is used to manage user identity, such as authentication and password policies, while an access policy is used to control access to specific resources, such as applications and data.
How can you use Azure AD Privileged Identity Management to protect privileged accounts?
You can use Azure AD Privileged Identity Management to protect privileged accounts by creating time-based and approval-based access policies, which help to limit access to privileged accounts and ensure that access is granted only when needed.
What is the purpose of role-based access control (RBAC) in Azure AD?
The purpose of role-based access control (RBAC) in Azure AD is to allow administrators to control access to Azure AD resources and services based on roles, rather than individual users or groups.
How does RBAC work in Azure AD?
RBAC in Azure AD works by defining roles that correspond to specific tasks or actions, and then assigning users or groups to those roles. Users or groups with a specific role have the necessary permissions to perform the corresponding tasks or actions.
