Microsoft Azure Security Center provides unified security management and advanced threat protection across hybrid cloud workloads. With Security Center, you can apply security policies across your workloads, limit your exposure to threats, and detect and respond to attacks.
You can select an existing Log Analytics workspace to store data collected by Security Center. To use your existing Log Analytics workspace:
• The workspace must be associated with your selected Azure subscription.
• At a minimum, you must have read permissions to access the workspace.
You can edit the default security policy for each of your Azure subscriptions in Security Center. To modify a security policy, you must be an owner, contributor, or security administrator of the subscription. To configure security policies in Security Center, do the following:
1. Sign in to the Azure portal.
2. On the Security Center dashboard, under General, select Security policy.
3. Select the subscription that you want to enable a security policy for.
4. In the Policy Components section, select Security policy.
This is the default policy that’s assigned by Security Center. You can turn on or off the available security recommendations.
5. When you finish editing, select Save.

Azure Security Center provides unified security management and advanced threat protection for workloads running in Azure, on-premises, and in other clouds. It delivers visibility and control over hybrid cloud workloads, active defenses that reduce your exposure to threats, and intelligent detection to help you keep pace with rapidly evolving cyber attacks.
Security Center is offered in two tiers:
• The Free tier is automatically enabled on all Azure subscriptions, and provides security policy, continuous security assessment, and actionable security recommendations to help you protect your Azure resources.
• The Standard tier extends the capabilities of the Free tier to workloads running in private and other public clouds, providing unified security management and threat protection across your hybrid cloud workloads. The Standard tier also adds advanced threat detection capabilities, which uses built-in behavioral analytics and machine learning to identify attacks and zero-day exploits, access and application controls to reduce exposure to network attacks and malware, and more. The Standard tier is free for the first 60 days. Read here more…….
What are OS Security Configurations?
Azure Security Center monitors security configurations using a set of over 150 recommended rules for hardening the OS, including rules related to firewalls, auditing, password policies, and more. If a machine is found to have a vulnerable configuration, a security recommendation is generated.
Customization of the rules can help organizations to control which configuration options are more appropriate for their environment. This feature enables users to set a customized assessment policy and apply it on all applicable machines in the subscription.
• Currently OS Security Configuration customization is available for Windows Server 2008, 2008R2, 2012, 2012R2 operating systems only.
• The configuration applies to all VMs and computers connected to all workspaces under the selected subscription.
• OS Security Configuration customization is available only on Security Center’s Standard tier.

Integrated Azure security solutions
Security Center makes it easy to enable integrated security solutions in Azure. Benefits include:
Simplified deployment: Security Center offers streamlined provisioning of integrated partner solutions. For solutions like antimalware and vulnerability assessment, Security Center can provision the needed agent on your virtual machines, and for firewall appliances, Security Center can take care of much of the network configuration required.
Integrated detections: Security events from partner solutions are automatically collected, aggregated, and displayed as part of Security Center alerts and incidents. These events also are fused with detections from other sources to provide advanced threat-detection capabilities.
Unified health monitoring and management: Customers can use integrated health events to monitor all partner solutions at a glance. Basic management is available, with easy access to advanced setup by using the partner solution.

Identity and Access Overview in Azure Security Center
Brute force attacks commonly target management ports as a means to gain access to a VM. If successful, an attacker can take control over the VM and establish a foothold into your environment.
One way to reduce exposure to a brute force attack is to limit the amount of time that a port is open. Management ports do not need to be open at all times. They only need to be open while you are connected to the VM, for example to perform management or maintenance tasks. When just in time is enabled, Security Center uses Network Security Group (NSG) rules, which restrict access to management ports so they cannot be targeted by attackers.
Azure Security Center’s advanced detection capabilities, helps you identify active threats targeting your Microsoft Azure resources and provides you with the insights needed to respond quickly
Custom Alert Rules
What are custom alert rules in Security Center?
Security Center has a set of predefined security alerts, which are triggered when a threat, or suspicious activity takes place. In some scenarios, you may want to create a custom alert to address specific needs of your environment.
Custom alert rules in Security Center allow you to define new security alerts based on data that is already collected from your environment. You can create queries, and the result of these queries can be used as criteria for the custom rule, and once this criteria is matched, the rule is executed. You can use computers security events, partner’s security solution logs or data ingested using APIs to create your custom queries.
Azure Security Center Playbooks
What is security playbook in Security Center?
Security playbook is a collection of procedures that can be executed from Security Center once a certain playbook is triggered from selected alert. Security playbook can help to automate and orchestrate your response to a specific security alert detected by Security Center. Security Playbooks in Security Center are based on Azure Logic Apps, which means you can use the templates that are provided under the security category in Logic Apps templates, you can modify them based on your needs, or you can create new playbooks using Azure Logic Apps workflow, and using Security Center as your trigger.
