As such, diagrams should document how company printers fit within the network.įirewalls and authentication tools also form part of the network architecture diagram. Many IT personnel forget that printers also send and receive data. These components are especially relevant when creating a logical topology. Network diagrams should track what data passes back-and-forth from these phones/tablets.Ĭable and wireless networks, along with switches, represent critical hubs in an organization’s digital framework. If employees take company devices off-campus, the risk is even higher. It’s unusual to lose a company computer, but it is more common for careless personnel to leave mobile devices lying about. Mobile devices present an even greater risk. Failing to logout or clicking unknown links can create opportunities for lost or stolen data. Quantifying that risk requires your team to understand what data passes between employee computers and the rest of the network.Īdditionally, network architecture diagrams are instructive for employees during their mandatory training. From managing email inboxes to logout procedures, employee responsibility can make all the difference in your cybersecurity program. As such, network diagrams help you visualize all possible vulnerabilities.Įmployees remain your biggest cybersecurity risk. While your server should be well-protected, most security breaches occur outside the server and attempt to infiltrate through data interception or back door intrusions. Either way, your servers form the “ground zero” of your network. Depending on the size and nature of your organization, you either employ onsite servers or cloud server hosting. This list is by no means exhaustive but can help you understand what is included in a network topology. What’s Included in a Physical Network Topology?Įssentially, your network diagram needs to account for every device, as well as any digital path that connects each device. As a general rule, logical topologies are more detailed than physical ones. Your logical topology resembles a digital roadmap of how data travels between these devices and hubs. In a network, data moves among many devices, from servers to printers to mobile devices and more. There are four different setups, which we will discuss in a bit. In most physical topologies, there is a hub – such as a wire and central server – tying together the entire network. Physical topology in network diagrams demonstrates connectivity. Network diagrams exist in two parts or topologies: Without this information, CISOs and security advisors cannot identify system vulnerabilities. These network infrastructure diagrams are essential to any cybersecurity program. Project managers often refer to network diagrams more broadly, but in the case of cybersecurity, it pertains to data flow across telecommunication hardware. Network diagrams refer to the documentation that identifies the flow of data within an organization. Cybersecurity experts at RSI Security are intimately knowledgeable about network diagrams and telecom operations.

At any time, feel free to reach out to our virtual security advisors for customized care. In this guide, we’ll define what a network diagram is and how it works. Without a small business network setup diagram, you become an easy target because your security team won’t be able to foresee and prevent a breach. That said, ignoring your network diagram upkeep is a critical mistake, especially if your business is small. The network keeps getting bigger-and so does the attack surface. New platforms and applications appear as well. Simply trusting vast swaths of the enterprise’s internal landscape won’t work because the ground is constantly shifting as employees move to new roles and require different access privileges. It’s a tug-of-war over access and control. The challenge comes down to this: making data and applications accessible to the right users in a way that is fast and efficient-and secure. Digital transformation – on any level – significantly increases a company’s attack vectors. Also, today’s fast-paced digital environment requires most businesses to expand rapidly. To be fair, documenting one’s network is tedious. Unfortunately, creating and maintaining these network architecture diagrams has become the IT equivalent to bookkeeping – it’s a fairly simple task that few people enjoy. Network diagrams form the blueprints for security programs in the 21st Century.
