Microsoft Azure is a dominant cloud hosting platform, serving around 70 percent of organizations worldwide. A popular hosting environment for SQL databases, Azure also provides a flexible way to run up to 200 cloud applications.
This flexibility is a game-changer for many businesses. But there’s a catch. To function properly, it’s essential to create a secure Azure environment. Otherwise, cloud apps and databases can leak sensitive data. Credentials may be at risk, and companies can suffer huge compliance penalties.
Fortunately, solutions exist. This blog will explain how to secure your cloud environment with Azure security best practices. And we will look at how to create a layered security strategy that goes beyond Microsoft’s controls.
Why is securing access to Azure so important?
Azure security matters because Microsoft’s cloud platform hosts a range of critical assets. Companies use Azure to host .Net apps for web applications or gaming DevOps. Azure storage accounts host SQL databases containing client data, while Kubernetes clusters support private cloud infrastructure.
Whatever Azure services companies rely on, security is a priority. Insecure Azure apps can leak data and provide an entry point for cyber attackers. And you cannot rely on Microsoft to cover every security challenge.
Azure clients have wide areas of responsibility to secure their cloud configuration. Clients need to restrict access to sensitive data. Users must manage access and exclude malicious actors. They also have to manage how data flows between cloud apps. The need for an Azure security policy is obvious when you put these tasks together.
Microsoft Azure security best practices
Any companies that rely on Microsoft’s cloud services should get to know Azure security best practices.
The best approach is adopting a layered strategy. Users should exploit security tools provided by Microsoft. But they should add additional security controls where necessary. These Azure security best practices will explain how the layered security approach works.
1. Map Azure assets and create a compliance strategy
The first step in layering Azure security is understanding the cloud environment. Before applying any of the best practices below, you must understand what assets need to be protected.
Map the cloud assets on your Azure platform. Include all apps and data stores, and classify data according to importance. You should know exactly where client data is stored and who has access to that data.
It is also advisable to create a clear compliance strategy for Azure environments. Define your core goals, including HIPAA, DCI-PSS, or GDPR compliance. Use these data security frameworks as a baseline to improve Azure security and meet regulatory requirements.
Track your compliance progress with the scoring tools in the Azure Security Center. The compliance dashboard provides detailed information about security levels and required actions.
2. Encrypt critical data
Data security on Azure apps is the responsibility of clients, not Microsoft. So take action to encrypt data and hide it from malicious actors.
Encrypt sensitive data at rest using Microsoft’s server-side symmetric key encryption tools. You can use these tools to segment data by importance. This ensures that operational data is available to employees. But financial or personal information is only accessible to users with specific encryption keys.
Azure Disk Encryption works alongside Microsoft’s SSE. It creates another layer of data security for virtual machines and data containers. This reduces the risk of attackers exploiting Virtual Hard Disk (VHD) files. Attackers will find it much harder to create virtual machines within Azure environments.
When you apply Azure encryption, key storage is your responsibility. Secure encryption keys in IAM controls in place to prevent unauthorized access. The Azure Key Vault is a good key management solution and integrates well with Azure app environments.
Users should also encrypt sensitive data in transit. Data constantly flows between Azure apps, remote devices, and on-premises workstations. VPN encryption provides a solution, adding another layer of protection above Azure security controls.
3. Create a backup and disaster recovery plan
A strong Azure security posture features a fall-back plan when systems fail, or attackers succeed. Microsoft offers an end-to-end DR service via Azure Site Recovery (ASR). Combine this with Azure Backup to create tailored data backup plans.
With an ASR failover plan, you can recover application states with minimal information loss. You might also add Azure Storage Replication, which regularly generates multiple copies of important files.
4. Secure sensitive data with robust controls
Encryption is not the only data security control for Azure users. Consider a range of additional tools and find a mix that secures sensitive data without compromising user experience. Options to think about include:
Activate auditing tools. Users can instruct Azure to audit databases. This creates a data stream that tracks database changes. Data visibility makes it easier for security teams to detect anomalies and unsafe user activity.
Add Azure SQL threat detection. Many Azure apps rely on SQL, but SQL presents critical security threats. Using SQL databases, turn on SQL threat detection to isolate security weaknesses and secure the threat surface.
Use Azure Firewall. Azure Firewall adds another layer of data security protection for Azure-hosted apps. You can manage firewall settings centrally, and coverage can increase as new apps come online. Cloud-native TLS inspection provides valuable protection against malware attacks.
Enable Azure Monitor alerts. Gain additional awareness by engaging Azure Monitor alerts. Users can target alerts at single resources and use many metrics to identify vulnerabilities. Azure Monitor Action Groups make it easy to automate alerts and deliver precise information when threats arise.
Implement Azure Defender. Defender is a subscription-based security service that leverages extended threat detection and response (XDR) and contextual security. It covers hybrid and multi-cloud environments, delivering threat protection and remediation advice. Azure Defender may well be a sensible addition when securing complex cloud environments,
Use Shared Access Signatures. Created via Active Directory, Shared Access Signatures let you manage access to Azure resources to third parties and employees for limited periods. Best practices include creating a SAS for all short-term network users, as it allows admins to set granular controls.
5. Manage access with IAM
Preventing illegitimate access to cloud infrastructure is one of the most important Azure security best practices. The best way to manage user access is by adding Identity and Access Management (IAM) to your security arsenal.
Microsoft provides a cloud-native IAM system called Azure Active Directory (AAD). AAD authenticates logins and compares user credentials to a secure Active Directory database.
IAM best practices for Azure include using AAD to set role-based access controls (RBAC). With RBAC, admins can put the Zero Trust ‘principle of least privilege’ into action. Every user has very limited privileges. Privileges only apply after users supply multiple credentials.
Role-based privileges have big practical benefits. Developers will not retain access to resources when their project involvement ends. Attackers obtaining their credentials will be relatively powerless. They will struggle to achieve Virtual Machine access. Breaching Azure SQL databases will be much harder.
Add another layer to your security posture by combining AAD with Single-Sign-On (SSO). SSO combines all cloud and on-premises assets. Remote workers can log in to the apps they need via a single sign-on portal.
Users can apply Multi-Factor Authentication (MFA) at this stage. This requests an extra authentication factor for each login, such as biometric data or one-time codes delivered to smartphones.
IP allowlisting also features in recommended Azure security best practices. Allowlisting lets you specify trusted IP addresses. You can add remote work devices or employee smartphones and exclude every other device until it passes MFA and IAM controls.
6. Add workload and VM protection
Azure security best practices include securing virtual machines via specialist controls. For instance, Azure includes the option of applying just-in-time controls for VMs. These Azure security controls allow users to access VMs for limited periods, removing the possibility of accessing assets after sessions expire.
VM controls also allow administrators to lock vulnerable ports and limit access to authorized users. Restrict access to RDP, WinRM, and SSH ports commonly used by VMs. Access should only be available when absolutely required.
You can apply controls easily by assigning workloads and VMs to Network Security Groups (NSGs). These groups define security procedures for each asset and add another protective layer via the Azure Firewall.
Additionally, remember to keep workload patches up to date. Unpatched Azure apps can be vulnerable to exploits. Automate software updates where possible and audit unpatched tools to minimize your exploit vulnerability.
7. Control the cloud perimeter with network security
Internal Azure cloud security works alongside general network security. Attackers can steal credentials from devices outside the cloud or launch attacks via internet-facing endpoints. This is why Azure’s best practices include measures to harden on-premises security. These measures can protect the whole network perimeter:
Track internet-facing cloud endpoints and minimize the contact between the wider web and company resources.
Use a Security Information and Event Management solution. SIEM tracks network traffic and identifies potential threats. Integrate it with Azure Defender to cover external and cloud-based vulnerabilities.
Apply network segmentation. Separate cloud endpoints from data centers and workstations with internet access.
Install a VPN or similar security tool to encrypt data and conceal user identities.
8. Audit user identities and access policies
Your Azure cloud security posture can weaken over time. What works now may degrade and create new vulnerabilities.
Azure security teams must audit every cloud security control and ensure continuing app and data protection. Audit app ownership regularly to ensure only active users have administrative privileges. Clean up Azure platforms by removing obsolete services, groups, and users.
Use the Azure Security Center to improve auditing procedures. The ASC includes machine learning analysis tools that provide feedback and suggest security posture improvements. Real-time monitoring and audit logs provide evidence to fine-tune your security setup.
How can NordLayer secure your access to Microsoft Azure?
Microsoft Azure cloud security requires a layered mix of internal cloud-based controls and solid external security. Users must protect data at the app level, followed by workgroups, platforms, and the entire company network.
The best practices listed above provide a roadmap to achieve security at the cloud level. Encrypt data and manage Active Directory identities. Leverage the Security Center to track user activity and run regular audits. And target virtual machines and apps with specific protection.
But that’s not enough. Add an extra security layer for rock-solid SaaS access control by safeguarding the network edge and protecting credentials outside the cloud.
NordLayer will help you achieve this. Encrypt in-transit data, apply for SSO, and screen access with IP allowlisting. Limit access to trusted IP addresses and exclude everything else – an important step towards a Zero Trust security posture.

These days, cybercrime is rampant. It’s no longer a matter of “if” you’re going to suffer an attack but “when” it will happen. All companies want to be ready for any crisis. And this is where a business continuity plan comes into play.
But what is a business continuity plan exactly? Why is it important? What should one include? Today, we’re exploring all these questions in-depth.
What is a business continuity plan?
A business continuity plan (BCP) is a document that sets guidelines for how an organization will continue its operations in the event of a disruption, whether it’s a fire, flood, other natural disaster or a cybersecurity incident. A BCP aims to help organizations resume operations without significant downtime.
Unfortunately, according to a 2020 Mercer survey, 51% of businesses across the globe don’t have a business continuity plan in place.
What’s the difference between business continuity and disaster recovery plans?
We often confuse the terms business continuity plan and disaster recovery plan. The two overlap and often work together, but the disaster recovery plan focuses on containing, examining, and restoring operations after a cyber incident. On the other hand, BCP is a broader concept that considers the whole organization. A business continuity plan helps organizations stay prepared for dealing with a potential crisis and usually encompasses a disaster recovery plan.
Importance of business continuity planning
The number of news headlines announcing data breaches has numbed us to the fact that cybercrime is very real and frequent and poses an existential risk to companies of all sizes and industries.
Consider that in 2021, approximately 37% of global organizations fell victim to a ransomware attack. Then consider that business interruption and restoration costs account for 50% of cyberattack-related losses. Finally, take into account that most cyberattacks are financially motivated and the global cost of cybercrime topped $6 trillion last year. The picture is quite clear — cybercrime is a lucrative venture for bad actors and potentially disastrous for those on the receiving end.
To thrive in these unpredictable times, organizations go beyond conventional security measures. Many companies develop a business continuity plan parallel to secure infrastructure and consider the plan a critical part of the security ecosystem. The Purpose of a business continuity plan is to significantly reduce the downtime in an emergency and, in turn, reduce the potential reputational damage and — of course — revenue losses.

Purpose of the Plan
Scope of the Plan
Budget
Timeline
The initial stage of developing a business continuity plan starts with a statement of the plan’s purpose, which explains the main objective of the plan, such as ensuring the organization’s ability to continue its operations during and after a disruptive event.
The Scope of the Plan outlines the areas or functions that the plan will cover, including business processes, personnel, equipment, and technology.
The Budget specifies the estimated financial resources required to implement and maintain the BCP. It includes costs related to technology, personnel, equipment, training, and other necessary expenses.
The Timeline provides a detailed schedule for developing, implementing, testing, and updating the BCP.
II. Risk Assessment
Identification of Risks
Prioritization of Risks
Mitigation Strategies
The Risk Assessment section of a Business Continuity Plan (BCP) is an essential part of the plan that identifies potential risks that could disrupt an organization’s critical functions.
The Identification of Risks involves identifying potential threats to the organization, such cybersecurity breaches, supply chain disruptions, power outages, and other potential risks. This step is critical to understand the risks and their potential impact on the organization.
Once the risks have been identified, the Prioritization of Risks follows, which helps determine which risks require the most attention and resources.
The final step in the Risk Assessment section is developing Mitigation Strategies to minimize the impact of identified risks. Mitigation strategies may include preventative measures, such as system redundancies, data backups, cybersecurity measures, as well as response and recovery measures, such as emergency protocols and employee training.
III. Emergency Response
Emergency Response Team
Communication Plan
Emergency Procedures
This section of the plan focuses on immediate actions that should be taken to ensure the safety and well-being of employees and minimize the impact of the event on the organization’s operations.
The Emergency Response Team is responsible for managing the response to an emergency or disaster situation. This team should be composed of individuals who are trained in emergency response procedures and can act quickly and decisively during an emergency. The team should also include a designated leader who is responsible for coordinating the emergency response efforts.
The Communication Plan outlines how information will be disseminated during an emergency situation. It includes contact information for employees, stakeholders, and emergency response personnel, as well as protocols for communicating with these individuals.
The Emergency Procedures detail the steps that should be taken during an emergency or disaster situation. The emergency procedures should be developed based on the potential risks identified in the Risk Assessment section and should be tested regularly to ensure that they are effective.
IV. Business Impact Analysis
The Business Impact Analysis (BIA) section of a Business Continuity Plan (BCP) is a critical step in identifying the potential impact of a disruption to an organization’s critical operations.
The Business Impact Analysis is typically conducted by a team of individuals who understand the organization’s critical functions and can assess the potential impact of a disruption to those functions. The team may include representatives from various departments, including finance, operations, IT, and human resources.
V. Recovery and Restoration
Procedures for recovery and restoration of critical processes
Prioritization of recovery efforts
Establishment of recovery time objectives
The Recovery and Restoration section of a Business Continuity Plan (BCP) outlines the procedures for recovering and restoring critical processes and functions following a disruption.
The Procedures for recovery and restoration of critical processes describe the steps required to restore critical processes and functions following a disruption. This may include steps such as relocating to alternate facilities, restoring data and systems, and re-establishing key business relationships.
The Prioritization section of the plan identifies the order in which critical processes will be restored, based on their importance to the organization’s operations and overall mission.
Recovery time objectives (RTOs) define the maximum amount of time that critical processes and functions can be unavailable following a disruption. Establishing RTOs ensures that recovery efforts are focused on restoring critical functions within a specific timeframe.
VI. Plan Activation
Plan Activation Procedures
The Plan Activation section is critical in ensuring that an organization can quickly and effectively activate the plan and respond to a potential emergency.
The Plan Activation Procedures describe the steps required to activate the BCP in response to a disruption. The procedures should be clear and concise, with specific instructions for each step to ensure a prompt and effective response.
VII. Testing and Maintenance
Testing Procedures
Maintenance Procedures
Review and Update Procedures
This section of the plan is critical to ensure that an organization can effectively respond to disruptions and quickly resume its essential functions.
Testing procedures may include scenarios such as natural disasters, cyber-attacks, and other potential risks. The testing procedures should include clear objectives, testing scenarios, roles and responsibilities, and evaluation criteria to assess the effectiveness of the plan.
The Maintenance Procedures detail the steps necessary to keep the BCP up-to-date and relevant.
The Review and Update Procedures describe how the BCP will be reviewed and updated regularly to ensure its continued effectiveness. This may involve conducting a review of the plan on a regular basis or after significant changes to the organization’s operations or threats.
What should a business continuity plan checklist include?
Organizations looking to develop a BCP have more than a few things to think through and consider. Variables such as the size of the organization, its IT infrastructure, personnel, and resources all play a significant role in developing a continuity plan. Remember, each crisis is different, and each organization will have a view on handling it according to all the variables in play. However, all business continuity plans will include a few elements in one way or another.
Clearly defined areas of responsibility
A BCP should define specific roles and responsibilities for cases of emergency. Detail who is responsible for what tasks and clarify what course of action a person in a specific position should take. Clearly defined roles and responsibilities in an emergency event allow you to act quickly and decisively and minimize potential damage.
Crisis communication plan
In an emergency, communication is vital. It is the determining factor when it comes to crisis handling. For communication to be effective, it is critical to establish clear communication pipelines. Furthermore, it is crucial to understand that alternative communication channels should not be overlooked and outlined in a business continuity plan.
Recovery teams
A recovery team is a collective of different professionals who ensure that business operations are restored as soon as possible after the organization confronts a crisis.
Alternative site of operations
Today, when we think of an incident in a business environment, we usually think of something related to cybersecurity. However, as discussed earlier, a BCP covers many possible disasters. In a natural disaster, determine potential alternate sites where the company could continue to operate.
Backup power and data backups
Whether a cyber event or a real-life physical event, ensuring that you have access to power is crucial if you wish to continue operations. In a BCP, you can often come across lists of alternative power sources such as generators, where such tools are located, and who should oversee them. The same applies to data. Regularly scheduled data backups can significantly reduce potential losses incurred by a crisis event.
Recovery guidelines
If a crisis is significant, a comprehensive business continuity plan usually includes detailed guidelines on how the recovery process will be carried out.
Business continuity planning steps
Here are some general guidelines that an organization looking to develop a BCP should consider:
Analysis
A business continuity plan should include an in-depth analysis of everything that could negatively affect the overall organizational infrastructure and operations. Assessing different levels of risk should also be a part of the analysis phase.
Design and development
Once you have a clear overview of potential risks your company could face, start developing a plan. Create a draft and reassess it to see if it takes into account even the smallest of details.
Implementation
Implement BCP within the organization by providing training sessions for the staff to get familiar with the plan. Getting everyone on the same page regarding crisis management is critical.
Testing
Rigorously test the plan. Play out a variety of scenarios in training sessions to learn the overall effectiveness of the continuity plan. By doing so, everyone on the team will be closely familiar with the business continuity plan’s guidelines.
Maintenance and updating
Because the threat landscape constantly changes and evolves, you should regularly reassess your BCP and take steps to update it. By making your continuity plan in tune with the times, you will be able to stay a step ahead of a crisis.
