The two most well-known types of networks are a Local Area Network (LAN) and a Wide Area Network (WAN), but more network options have emerged as technology has improved. Today's network architecture is complex and is faced with a threat environment that is always changing and attackers that are always trying to find and exploit vulnerabilities. They also relay messages between subnetworks and may be analog or digital. A wireless network consists of several components that support communications using radio or light waves propagating through an air medium. Network security is protecting the integrity and usability of network data, including both software and hardware technologies. The actual physical system can span many miles; for example, locks and dams, pipelines, and electric transmission and distribution systems can have many non-contiguous components. For example, a wireless printer (a resource) may receive a command from a computer over a network, either with a direct connection or wirelessly. All Right Reserved. Tasks are allocated equally without a hierarchy, which is why P2P can also be called a distributed network. There are multiple layers of software and hardware that prevent numerous threats from penetrating, damaging, and spreading through the network. Repeaters – Repeaters regenerate network signals that are distorted. In the diagram below, an attacker must compromise only one server to gain access to the Web applications provided on the same system. Thus, city resources are easily shareable within different departmental facilities. For example, users would access a virtual machine on their device but none of the applications are actually run on the personal device. SIEM gathers the relevant and required data from multiple sources to help identify deviations and take appropriate actions. While the above three architecture components compose the core of a network, other components often come up when discussing network security. What are the different types of network security? The two most common architecture types are Peer-to-Peer (P2P) and tiered, also referred to as client-server. We use your data to personalize and improve your experience as an user and to provide the services you request from us. NAC identifies what users and devices are allowed on the network. When Should I Become a Certified Network Defender? What Is Network Security? Within a tiered network, if a server goes down, clients are more vulnerable because the network is not as distributed as in a P2P network. Penetration testing and computer forensics will help strengthen network security. RSI Security is an Approved Scanning Vendor (ASV) and Qualified Security Assessor (QSA). All of these things make it harder for an attacker to gain access to your crown jewels and easier for you to isolate and respond to breaches when they occur.
