Top 7 Azure Security Tools and Functions 

Besides helping companies accomplish their business objectives, Azure is well known for its security services. With strong uptime, they can safely rely on the services of this cloud-native platform. It provides a variety of tools that can be used to implement and maintain security in your organisation.

Here are the top 7 Azure  Security Tools that you need to know about in today’s Cloud Computing  world:  

1) Microsoft Sentinel

Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) solution. It helps detect, prevent, and respond to security threats across your entire organisation. Sentinel collects and analyses data from various sources, providing a comprehensive view of security issues. It uses Artificial Intelligence to identify and mitigate threats.

Best Practices:

a) Regularly Update Threat Detection Rules: Keep your detection rules up to date to identify the latest security threats. This ensures your system can effectively recognise and respond to new types of attacks.

b) Integrate All Relevant Data Sources: Connect all your data sources to Sentinel for a comprehensive security overview. This helps in detecting patterns and anomalies across your entire environment.

c) Use Automated Response Playbooks: Implement automated responses for common threats to reduce response time. This ensures quick action on detected threats, minimising potential damage.

2) Azure Firewall 

It is a cloud-based network security service that safeguards your Azure Virtual Network resources. It offers both application and network-level filtering rules, helping to block malicious traffic and prevent unauthorised access. Azure Firewall is highly available and can scale to meet your network traffic needs. It provides logging and analytics to monitor and improve your security posture.

Best Practices:

a) Define Clear Traffic Filtering Rules: Create specific rules to control traffic flow and block malicious activity. This helps ensure only legitimate traffic can access your resources.

b) Enable Logging for All Activities: Turn on logging to track all firewall activities and identify any suspicious behaviour. Logs provide valuable insights for auditing and troubleshooting.

c) Regularly Review and Update Rules: Periodically check and update your firewall rules to adapt to new threats. This keeps your security measures current and effective.

3) Azure Resource Locks 

Azure Resource Locks help prevent accidental deletion or modification of your critical resources. By applying locks, you can ensure that important resources are protected from unintentional changes. There are two types of locks: CanNotDelete and ReadOnly. These locks provide a layer of security by enforcing restrictions on resource modifications.

Best Practices:

a) Apply Locks to Critical Resources: Use locks to safeguard essential resources from accidental changes. This prevents costly mistakes that could disrupt your operations.

b) Use ReadOnly Locks for Sensitive Data: Implement ReadOnly locks on resources that should not be modified. This ensures that the data remains unchanged and secure.

c) Regularly Review Lock Configurations: Check your lock settings periodically to ensure they meet your security needs. Adjust locks as necessary to protect your most important resources.

4) Azure Key Vault

It is a cloud service for storing and managing sensitive information like keys, secrets, and certificates. It helps safeguard cryptographic keys used by cloud applications and services. Key Vault simplifies key management and ensures that your secrets are protected with Hardware Security Modules (HSMs). It also enables secure access to your secrets and keys using managed identities.

Best Practices:

a) Regularly Rotate Keys and Secrets: Change your keys and secrets frequently to enhance security. Regular rotation reduces the risk of exposure and unauthorised access.

b) Set Up Access Policies: Define who can manage and use your keys and secrets. Access policies ensure only authorised users have the necessary permissions.

c) Monitor Access and Usage: Use Azure monitoring tools to track who is accessing your keys and secrets. This helps detect and respond to suspicious activities promptly.

5) Azure AD Multi-factor Authentication 

Authentication Azure AD Multi-factor Authentication (MFA) adds an additional layer of security to your user sign-ins. It requires users to provide two or more verification methods, such as a password and a mobile app notification. MFA helps protect against credential theft and unauthorised access. It is an essential tool for enhancing the security of user accounts.

Best Practices:

a) Enable MFA for All Users: Ensure that every user in your organisation uses MFA. This greatly reduces the risk of account breaches.

b) Regularly Review Authentication Methods: Check and update the verification methods to keep them effective and secure. Ensuring the latest methods are used helps maintain strong protection.

c) Educate Users on MFA Importance: Inform your users about the Microsoft Azure Benefits of MFA and how to use it properly. Education ensures users understand and effectively use this security measure.

6) Azure SQL Database Always Encrypted

Azure SQL Database Always Encrypted helps protect sensitive data by ensuring that it remains encrypted during storage and transit. This feature allows you to encrypt confidential data within your database without revealing the encryption keys to the database system.

Only authorised applications and users can access the encrypted data. 'Always Encrypted' ensures that sensitive information, such as credit card numbers and personal identifiers, is secure.

Best Practices:

a) Encrypt All Sensitive Data Fields: Make sure to encrypt fields containing sensitive information. This protects your most valuable data from unauthorised access.

b) Use Strong Encryption Algorithms: Apply robust encryption methods to secure your data. Strong algorithms provide better protection against decryption attempts.

c) Regularly Rotate Encryption Keys: Change encryption keys periodically to enhance security. Key rotation helps prevent long-term exposure of encrypted data.

7) Azure Active Directory Identity Protection

Azure Active Directory Identity Protection helps detect and respond to identity-based risks. It uses Machine Learning to identify suspicious activities, such as unusual sign-in attempts and potential account compromises. Identity Protection provides detailed reports and alerts to help you address these risks promptly. It also offers automated responses to mitigate identified risks.

Best Practices:

a) Enable Risk-based Conditional Access Policies: Use policies that adapt based on detected risks to control access. This ensures that legitimate users can access sensitive resources.

b) Regularly Review Identity Protection Reports: Check the reports and alerts frequently to stay informed about potential threats. Regular reviews help you respond quickly to any issues.

c) Educate Users on Suspicious Activities: Teach your users to recognise and report unusual account behaviour. User awareness helps in early detection and prevention of security incidents.
