CIS_Azure_1.1.0 9.1 CIS_Azure_1.1.0_9.1 CIS Microsoft Azure Foundations Benchmark recommendation 9.1 9 AppService Ensure App Service Authentication is set on Azure App Service Shared The customer is responsible for implementing this recommendation. Azure App Service Authentication is a feature that can prevent anonymous HTTP requests from reaching the API app, or authenticate those that have tokens before they reach the API app. If an anonymous request is received from a browser, App Service will redirect to a logon page. To handle the logon process, a choice from a set of identity providers can be made, or a custom authentication mechanism can be implemented. link 5
CIS_Azure_1.3.0 9.1 CIS_Azure_1.3.0_9.1 CIS Microsoft Azure Foundations Benchmark recommendation 9.1 9 AppService Ensure App Service Authentication is set on Azure App Service Shared The customer is responsible for implementing this recommendation. Azure App Service Authentication is a feature that can prevent anonymous HTTP requests from reaching the API app, or authenticate those that have tokens before they reach the API app. If an anonymous request is received from a browser, App Service will redirect to a logon page.

CIS_Azure_1.4.0 9.1 CIS_Azure_1.4.0_9.1 CIS Microsoft Azure Foundations Benchmark recommendation 9.1 9 AppService Ensure App Service Authentication is set up for apps in Azure App Service Shared The customer is responsible for implementing this recommendation. Azure App Service Authentication is a feature that can prevent anonymous HTTP requests from reaching the API app, or authenticate those that have tokens before they reach the API app. If an anonymous request is received from a browser, App Service will redirect to a logon page.

CIS_Azure_2.0.0 9.1 CIS_Azure_2.0.0_9.1 CIS Microsoft Azure Foundations Benchmark recommendation 9.1 9 Ensure App Service Authentication is set up for apps in Azure App Service Shared This is only required for App Services which require authentication. Enabling on site like a marketing or support website will prevent unauthenticated access which would be undesirable. Adding Authentication requirement will increase cost of App Service and require additional security components to facilitate the authentication. Azure App Service Authentication is a feature that can prevent anonymous HTTP requests from reaching a Web Application or authenticate those with tokens before they reach the app. If an anonymous request is received from a browser, App Service will redirect to a logon page. To handle the logon process, a choice from a set of identity providers can be made, or a custom authentication mechanism can be implemented. By Enabling App Service Authentication, every incoming HTTP request passes through it before being handled by the application code. It also handles authentication of users with the specified provider (Azure Active Directory, Facebook, Google, Microsoft Account, and Twitter), validation, storing and refreshing of tokens, managing the authenticated sessions and injecting identity information into request headers. link 5

NIST_SP_800-171_R3_3 .1.3 NIST_SP_800-171_R3_3.1.3 NIST 800-171 R3 3.1.3 Access Control Information Flow Enforcement Shared Information flow control regulates where CUI can transit within a system and between systems (versus who can access the information) and without explicit regard to subsequent accesses to that information. Flow control restrictions include keeping CUI from being transmitted in the clear to the internet, blocking outside traffic that claims to be from within the organization, restricting requests to the internet that are not from the internal web proxy server, and limiting information transfers between organizations based on data structures and content. Organizations commonly use information flow control policies and enforcement mechanisms to control the flow of CUI between designated sources and destinations (e.g., networks, individuals, and devices) within systems and between interconnected systems. Flow control is based on characteristics of the information or the information path. Enforcement occurs in boundary protection devices (e.g., encrypted tunnels, routers, gateways, and firewalls) that use rule sets or establish configuration settings that restrict system services, provide a packet-filtering capability based on header information, or provide a message-filtering capability based on message content (e.g., implementing key word searches or using document characteristics). Organizations also consider the trustworthiness of filtering and inspection mechanisms (i.e., hardware, firmware, and software components) that are critical to information flow enforcement. Transferring information between systems that represent different security domains with different security policies introduces the risk that such transfers violate one or more domain security policies. In such situations, information owners or stewards provide guidance at designated policy enforcement points between interconnected systems. Organizations consider mandating specific architectural solutions when required to enforce specific security policies. Enforcement includes prohibiting information transfers between interconnected systems (i.e., allowing information access only), employing hardware mechanisms to enforce one-way information flows, and implementing trustworthy regrading mechanisms to reassign security attributes and security labels. Enforce approved authorizations for controlling the flow of CUI within the system and between connected systems. 46
NIST_SP_800-53_R5.1.1 AC.4 NIST_SP_800-53_R5.1.1_AC.4 NIST SP 800-53 R5.1.1 AC.4 Access Control Information Flow Enforcement Shared Enforce approved authorizations for controlling the flow of information within the system and between connected systems based on [Assignment: organization-defined information flow control policies]. Information flow control regulates where information can travel within a system and between systems (in contrast to who is allowed to access the information) and without regard to subsequent accesses to that information. Flow control restrictions include blocking external traffic that claims to be from within the organization, keeping export-controlled information from being transmitted in the clear to the Internet, restricting web requests that are not from the internal web proxy server, and limiting information transfers between organizations based on data structures and content. Transferring information between organizations may require an agreement specifying how the information flow is enforced (see CA-3). Transferring information between systems in different security or privacy domains with different security or privacy policies introduces the risk that such transfers violate one or more domain security or privacy policies. In such situations, information owners/stewards provide guidance at designated policy enforcement points between connected systems. Organizations consider mandating specific architectural solutions to enforce specific security and privacy policies. Enforcement includes prohibiting information transfers between connected systems (i.e., allowing access only), verifying write permissions before accepting information from another security or privacy domain or connected system, employing hardware mechanisms to enforce one-way information flows, and implementing trustworthy regrading mechanisms to reassign security or privacy attributes and labels. Organizations commonly employ information flow control policies and enforcement mechanisms to control the flow of information between designated sources and destinations within systems and between connected systems. Flow control is based on the characteristics of the information and/or the information path. Enforcement occurs, for example, in boundary protection devices that employ rule sets or establish configuration settings that restrict system services, provide a packet-filtering capability based on header information, or provide a message-filtering capability based on message content. Organizations also consider the trustworthiness of filtering and/or inspection mechanisms (i.e., hardware, firmware, and software components) that are critical to information flow enforcement. Control enhancements 3 through 32 primarily address cross-domain solution needs that focus on more advanced filtering techniques, in-depth analysis, and stronger flow enforcement mechanisms implemented in cross-domain products, such as high-assurance guards. Such capabilities are generally not available in commercial off-the-shelf products. Information flow enforcement also applies to control plane traffic (e.g., routing and DNS). 44
