Network Security |
Establish network segmentation boundaries |
Shared |
**Security Principle:**
Ensure that your virtual network deployment aligns to your enterprise segmentation strategy defined in the GS-2 security control. Any workload that could incur higher risk for the organization should be in isolated virtual networks.
Examples of high-risk workload include:
- An application storing or processing highly sensitive data.
- An external network-facing application accessible by the public or users outside of your organization.
- An application using insecure architecture or containing vulnerabilities that cannot be easily remediated.
To enhance your enterprise segmentation strategy, restrict or monitor traffic between internal resources using network controls. For specific, well-defined applications (such as a 3-tier app), this can be a highly secure "deny by default, permit by exception" approach by restricting the ports, protocols, source, and destination IPs of the network traffic. If you have many applications and endpoints interacting with each other, blocking traffic may not scale well, and you may only be able to monitor traffic.
**Azure Guidance:**
Create a virtual network (VNet) as a fundamental segmentation approach in your Azure network, so resources such as VMs can be deployed into the VNet within a network boundary. To further segment the network, you can create subnets inside VNet for smaller sub-networks.
Use network security groups (NSG) as a network layer control to restrict or monitor traffic by port, protocol, source IP address, or destination IP address.
You can also use application security groups (ASGs) to simplify complex configuration. Instead of defining policy based on explicit IP addresses in network security groups, ASGs enable you to configure network security as a natural extension of an application's structure, allowing you to group virtual machines and define network security policies based on those groups.

Configuration Management |
Restrict, disable, or prevent the use of nonessential programs, functions, ports, protocols, and services. |
Shared |
Microsoft and the customer share responsibilities for implementing this requirement. |
Restricting the use of nonessential software (programs) includes restricting the roles allowed to approve program execution; prohibiting auto-execute; program blacklisting and whitelisting; or restricting the number of program instances executed at the same time. The organization makes a security-based determination which functions, ports, protocols, and/or services are restricted. Bluetooth, File Transfer Protocol (FTP), and peer-to-peer networking are examples of protocols organizations consider preventing the use of, restricting, or disabling. |

System and Communications Protection |
Monitor, control, and protect communications (i.e., information transmitted or received by organizational systems) at the external boundaries and key internal boundaries of organizational systems. |
Shared |
Microsoft and the customer share responsibilities for implementing this requirement. |
Communications can be monitored, controlled, and protected at boundary components and by restricting or prohibiting interfaces in organizational systems. Boundary components include gateways, routers, firewalls, guards, network-based malicious code analysis and virtualization systems, or encrypted tunnels implemented within a system security architecture (e.g., routers protecting firewalls or application gateways residing on protected subnetworks). Restricting or prohibiting interfaces in organizational systems includes restricting external web communications traffic to designated web servers within managed interfaces and prohibiting external traffic that appears to be spoofing internal addresses.
Organizations consider the shared nature of commercial telecommunications services in the implementation of security requirements associated with the use of such services. Commercial telecommunications services are commonly based on network components and consolidated management systems shared by all attached commercial customers and may also include third party-provided access lines and other service elements. Such transmission services may represent sources of increased risk despite contract security provisions. |

Access Control |
Information Flow Enforcement |
Shared |
n/a |
The information system enforces approved authorizations for controlling the flow of information within the system and between interconnected systems based on [Assignment: organization-defined information flow control policies].
Supplemental Guidance: Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to that information. Flow control restrictions include, for example, keeping export-controlled information from being transmitted in the clear to the Internet, blocking outside traffic that claims to be from within the organization, restricting web 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. Transferring information between information systems representing different security domains with different security policies introduces risk that such transfers violate one or more domain security policies. In such situations, information owners/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, for example: (i) prohibiting information transfers between interconnected systems (i.e., allowing access only); (ii) employing hardware mechanisms to enforce one-way information flows; and (iii) implementing trustworthy regarding mechanisms to reassign security attributes and security labels.
Organizations commonly employ information flow control policies and enforcement mechanisms to control the flow of information between designated sources and destinations (e.g., networks, individuals, and devices) within information systems and between interconnected systems. Flow control is based on the characteristics of the information and/or the information path. Enforcement occurs, for example, in boundary protection devices (e.g., gateways, routers, guards, encrypted tunnels, firewalls) that employ rule sets or establish configuration settings that restrict information system services, provide a packet-filtering capability based on header information, or message- filtering capability based on message content (e.g., implementing key word searches or using document characteristics). Organizations also consider the trustworthiness of filtering/inspection mechanisms (i.e., hardware, firmware, and software components) that are critical to information flow enforcement. Control enhancements 3 through 22 primarily address cross-domain solution needs which focus on more advanced filtering techniques, in-depth analysis, and stronger flow enforcement mechanisms implemented in cross-domain products, for example, high-assurance guards. Such capabilities are generally not available in commercial off-the-shelf information technology products. Related controls: AC-3, AC-17, AC-19, AC-21, CM-6, CM-7, SA-8, SC-2, SC-5, SC-7, SC-18.

Information flow control regulates where information can travel 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 the following: keeping export-controlled information 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 information between designated sources and destinations (e.g., networks, individuals, and devices) within systems and 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 access only); employing hardware mechanisms to enforce one-way information flows; and implementing trustworthy regrading mechanisms to reassign security attributes and security labels. |

Organizations apply systems security engineering principles to new development systems or systems undergoing major upgrades. For legacy systems, organizations apply systems security engineering principles to system upgrades and modifications to the extent feasible, given the current state of hardware, software, and firmware components within those systems. The application of systems security engineering concepts and principles helps to develop trustworthy, secure, and resilient systems and system components and reduce the susceptibility of organizations to disruptions, hazards, and threats. Examples of these concepts and principles include developing layered protections; establishing security policies, architecture, and controls as the foundation for design; incorporating security requirements into the system development life cycle; delineating physical and logical security boundaries; ensuring that developers are trained on how to build secure software; and performing threat modeling to identify use cases, threat agents, attack vectors and patterns, design patterns, and compensating controls needed to mitigate risk. Organizations that apply security engineering concepts and principles can facilitate the development of trustworthy, secure systems, system components, and system services; reduce risk to acceptable levels; and make informed risk-management decisions.

The system owner of the higher security domain of connected security domains would be most familiar with the controls required to protect the more sensitive information and as such is best placed to manage any shared components of gateways. In some cases where multiple security domains from different agencies are connected to a gateway, it may be more appropriate to have a qualified third party manage the gateway on behalf of all connected agencies.

Ensure overall network security controls are implemented including the following:
(a) dedicated firewalls at all segments. All external-facing firewalls must be deployed on High Availability (HA) configuration and “fail-close” mode activated. Deploy different brand name/model for two firewalls located in sequence within the same network path;
(b) IPS at all critical network segments with the capability to inspect and monitor encrypted network traffic;
(c) web and email filtering systems such as web-proxy, spam filter and anti-spoofing controls;
(d) endpoint protection solution to detect and remove security threats including viruses and malicious software;
(e) solution to mitigate advanced persistent threats including zero-day and signatureless malware; and
(f) capture the full network packets to rebuild relevant network sessions to aid forensics in the event of incidents. |

TRUST SERVICES CRITERIA AND POINTS OF FOCUS
inventories, classifies, and manages information assets.
• Restricts Logical Access — Logical access to information assets, including hardware, data (at-rest, during processing, or in transmission), software, administrative
authorities, mobile devices, output, and offline system components is restricted
through the use of access control software and rule sets.
• Identifies and Authenticates Users — Persons, infrastructure, and software are
identified and authenticated prior to accessing information assets, whether locally
or remotely.
• Considers Network Segmentation — Network segmentation permits unrelated portions of the entity's information system to be isolated from each other.
• Manages Points of Access — Points of access by outside entities and the types of
data that flow through the points of access are identified, inventoried, and managed. The types of individuals and systems using each point of access are identified,
documented, and managed.
• Restricts Access to Information Assets — Combinations of data classification, separate data structures, port restrictions, access protocol restrictions, user identification, and digital certificates are used to establish access-control rules for information assets.
• Manages Identification and Authentication — Identification and authentication requirements are established, documented, and managed for individuals and systems
accessing entity information, infrastructure, and software.
• Manages Credentials for Infrastructure and Software — New internal and external
infrastructure and software are registered, authorized, and documented prior to being granted access credentials and implemented on the network or access point.
Credentials are removed and access is disabled when access is no longer required
or the infrastructure and software are no longer in use.
• Uses Encryption to Protect Data — The entity uses encryption to supplement other
measures used to protect data at rest, when such protections are deemed appropriate based on assessed risk.
• Protects Encryption Keys — Processes are in place to protect encryption keys during generation, storage, use, and destruction |

channel (for example, FTP site, router port) are restricted.
• Protects Identification and Authentication Credentials — Identification and authentication credentials are protected during transmission outside its system boundaries.
• Requires Additional Authentication or Credentials — Additional authentication information or credentials are required when accessing the system from outside its
boundaries.
• Implements Boundary Protection Systems — Boundary protection systems (for example, firewalls, demilitarized zones, and intrusion detection systems) are implemented to protect external access points from attempts and unauthorized access and
are monitored to detect such attempts |

• Restricts the Ability to Perform Transmission — Data loss prevention processes and
technologies are used to restrict ability to authorize and execute transmission,
movement, and removal of information.
• Uses Encryption Technologies or Secure Communication Channels to Protect Data
— Encryption technologies or secured communication channels are used to protect
transmission of data and other communications beyond connectivity access points.
• Protects Removal Media — Encryption technologies and physical asset protections
are used for removable media (such as USB drives and backup tapes), as appropriate.
• Protects Mobile Devices — Processes are in place to protect mobile devices (such
as laptops, smart phones, and tablets) that serve as information assets |
