Information systems that perform or support critical business processes require additional or enhanced security controls. Some authors (for example Willard, in General Topology ) use the term frontier instead of boundary in an attempt to avoid confusion with a different definition used in algebraic topology and the theory of manifolds . Since Ops first quote describes IP, My answer is correct contextually, but not necessarily the only valid answer to the general question "what does network boundary mean?". Your organization's protection strategy should carefully orchestrate and thoroughly document the interplay among the enterprise, hosting environment, and high-value system boundary protection capabilities. en For that reason only basic filtering and access control functions are performed by the networks, whereas more specific security functions (e.g. Notional Enterprise Architecture. The first step in the six step risk management framework (RMF) process is categorizing your system. Boundary protection is the "monitoring and control of communications at the external boundary of an information system to prevent and detect malicious and other unauthorized communication." NIST SP 800-37, Revision 1, has a flexible definition: "the set of information resources allocated to an information system." Do they emit light of the same energy? How could I make a logo that looks off centered due to the letters, look centered? Today, many attackers focus on exploiting systems that they can reach across the internet; they are constantly probing perimeters for vulnerabilities and information needed to build their attack plan. Why did DEC develop Alpha instead of continuing with MIPS? In Cybersecurity Architecture, Part 1: Cyber Resilience and Critical Service, we talked about the importance of identifying and prioritizing critical or high-value services and the assets and data that support them. Incorporating a system architecture review into your security assessment can help stakeholders gain a comprehensive understanding of risk to the mission or business. Required inbound and outbound traffic for high-value systems should be understood and documented at the IP address, port, and protocol level of detail. Notations used for boundary of a set S include bd( S ), fr( S ), and ∂ S {\displaystyle \partial S} . What boundary protection capabilities apply to the high-value system? (For example, traffic to and from the high-value system is restricted to only traffic that is required for the operation of the system.). This is used to distinguish a network that has its own hosts and addresses. In addition, all of the traffic entering and exiting the high-value system environment should be inspected. A machine that is not directly connected to your LAN is outside your network boundary, and you cannot contact it. What does boundary mean? It is by definition a realm of connected machines that can communicate using the OSI Data Link layer (layer 2). When the CERT Division of the SEI performs security architecture reviews, our teams of three to four people often include system engineers, software developers, penetration testers, and security analysts. In this context, "network" is synonymous with "LAN" or local area network. The term originates from before the Internet, when the only kinds of networks were LANs.

Regardless, we recommend employing boundary protection specific to the high-value system to ensure that it is sufficiently isolated, including from the rest of the enterprise. Whether such a boundary is too large can depend on the standard in use: NIST guidance might consider such services outside the boundary, while the PCI standard might include them. Bridges, brokers and boundary spanners facilitate transactions and the flow of information between people or groups who either have no physical or cognitive access to one another, or alternatively, who have no basis on which to trust each other. In this post, we'll introduce our approach for reviewing the security of the architecture of information systems that deliver or support these services. See more. One method is to identify the potential impact to the organization (such as Low, Moderate, or High) resulting from the loss of confidentiality, integrity, or availability (the "CIA Triad") of the information and information system. In Part 3 of our Cybersecurity Architecture series, we'll discuss three more focus areas: Asset Management, Network Segmentation, and Configuration Management. The boundary data is an approximation. Review and analyze the information, documenting findings or identifying additional information that needs to be collected. The CIA requirements for the other systems that reside in the hosting environment, might be very different from the CIA requirements for the high-value system.
