You are the SOC team member working with the application and infrastructure teams architecting the resource architecture for the new web application that uses containers and Azure SQL.
You are accountable to make sure the workloads are secure with Azure Defender and offer options for non-protected workloads.
What type of protection is delivered by Azure Defender for services on DNS?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: D Option D is correct as it is one of the advantages of using Azure defender for DNS.
Reference:
Azure Defender is a cloud-native security solution that provides unified security management and advanced threat protection for hybrid cloud workloads. Azure Defender is designed to work with a variety of services in Azure, including virtual machines, SQL databases, storage accounts, and more.
One of the services that Azure Defender provides protection for is DNS (Domain Name System). DNS is a critical service that is used to translate domain names (e.g., www.example.com) into IP addresses. DNS is often targeted by attackers as a way to exfiltrate data, communicate with C&C servers, and perform other malicious activities.
To protect against these types of attacks, Azure Defender provides several types of protection for DNS services. The answer options provided are as follows:
A. Data exfiltration from your Azure resources using DNS tunneling.
DNS tunneling is a technique that allows attackers to bypass network security controls by encapsulating other protocols within DNS requests and responses. Azure Defender is designed to detect and block DNS tunneling attempts, which can be used to exfiltrate data from Azure resources.
B. Malware communicating with C&C server.
Malware often communicates with command-and-control (C&C) servers using DNS requests. Azure Defender is designed to detect and block DNS requests that are associated with known malware families.
C. Communication with malicious domains as phishing and crypto mining.
Attackers often use phishing and crypto mining campaigns to steal sensitive data or compute resources from victims. These campaigns often involve communication with malicious domains using DNS requests. Azure Defender is designed to detect and block DNS requests that are associated with known phishing and crypto mining campaigns.
D. On-premises DNS communication with malicious DNS resolvers.
In some cases, attackers may attempt to redirect DNS requests to malicious DNS resolvers in order to intercept or manipulate network traffic. Azure Defender is designed to detect and block DNS requests that are associated with known malicious DNS resolvers.
In summary, Azure Defender provides protection for DNS services by detecting and blocking DNS tunneling attempts, malware communications, communication with malicious domains, and communication with malicious DNS resolvers.
