17 Cyber Security Concepts ExplainedCyber security is the foundation of all other information security systems. Cybersecurity is a mature market with powerful and established suppliers and start-ups that constantly bring in new and better technologies. This article will introduce the key concepts of modern network security architecture. A cybersecurity architect refers to a series of responsibilities related to cloud security architecture, cybersecurity architecture, and data security architecture. Depending on the size of the organization, there may be one person responsible for each module, or there may be one person responsible for the entire module. No matter which way it is, the organization needs to appoint relevant responsible persons and authorize them to make critical mission decisions. Network risk assessment refers to the entire process of detecting, identifying, controlling and eliminating known or potential security risks and hidden dangers in a network. It is one of the necessary measures for enterprise network security management. Through network security assessment, comprehensively sort out the assets in the network, understand the current security risks and hidden dangers, and carry out targeted security reinforcement to ensure the safe operation of the network. Zero Trust Architecture (Zero Trust Architecture, ZTA) is a cybersecurity paradigm. The principle of its industrial vpn router is to assume that all participants in the network are untrusted. Therefore, it protects the assets on the network rather than the network itself. Because it is related to the user, the agent will decide whether to approve each access request based on the risk status calculated by context factors such as application, location, user, device, time and data sensitivity. As the name suggests, ZTA is an architecture rather than a product. You can't buy it, but you can develop it based on some technical elements. A network firewall is a mature industrial Ethernet router with a series of functions designed to prevent anyone from directly accessing the network server hosting the organization's applications and data. Network firewalls can be used for both local networks and the cloud. For the cloud, there are some cloud-centric products and methods deployed by IaaS providers to achieve some of the same functions. The application of a secure Web gateway has evolved from optimizing Internet bandwidth in the past to protecting users from malicious content from the Internet. Functions such as URL filtering, anti-malware, decryption and inspection of websites accessed via HTTPS, data loss protection (DLP), and Cloud Access Security Proxy (CASB) have become standard configurations. Remote access relies less on virtual private networks (VPNS) and more on zero-trust network access (ZTNA). Zero Trust network access makes assets invisible to users and accesses individual applications using context configuration files. Intrusion Prevention systems (IPS) detect and block attacks by placing IPS devices on unpatched servers to prevent irreparable vulnerabilities (for example, packaged applications that service providers no longer support). The IPS function is usually included in other security products, but there are also independent products. IPS, or vpn industrial routers, are experiencing a revival as cloud-native control has gradually incorporated into vpn industrial routers. Network access control provides visibility into all content on the network and policy-based control over access to the network infrastructure. Policies can define access rights based on the user's role, authentication, or other factors. Network packet proxy devices process network traffic so that other monitoring devices (such as those dedicated to network performance monitoring and security-related monitoring) can operate more effectively. These functions include packet data filtering for identifying risk levels, allocating packet loads, and hardware-based timestamp insertion.
