Network Security

What are the top wireless network security risks? Wireless networks are vulnerable to a wide range of security risks due to their inherent characteristics, such as broadcast nature, lack of physical boundaries, and dependence on radio waves. Here are some of the top wireless network security risks: Unauthorized access: Wireless networks are vulnerable to unauthorized…

What is intrusion detection? Intrusion Detection Systems (IDS) monitor the traffic flowing through your network and sound an alarm when they spot suspicious network activity. There are primarily two types of IDS: Network Intrusion Detection Systems (NIDS): NIDS monitors the entire network, looking out for abnormal patterns or activities. NIDS is the go-to choice for…

What is MSCHAPv2 used for? MSCHAPv2 (Microsoft Challenge Handshake Authentication Protocol version 2) is a widely used authentication protocol primarily used for securing remote access connections in Virtual Private Networks (VPNs). It is an extension of the original MSCHAP protocol developed by Microsoft. MSCHAPv2 is used to verify the identity of a user or device…

What is MS-CHAP used for? MS-CHAP, which stands for Microsoft Challenge Handshake Authentication Protocol, is a widely used authentication protocol in computer networking and security. It is primarily used for secure authentication of users in Point-to-Point Protocol (PPP) connections, which are often used for remote access to corporate networks, virtual private networks (VPNs), and dial-up…

What is network detection and response (NDR)? Network Detection and Response (NDR) is a cybersecurity solution designed to detect and respond to threats within network traffic. Unlike traditional security measures that focus on preventing threats at the perimeter (such as firewalls and antivirus software), NDR operates by continuously monitoring internal network traffic to identify suspicious…

Addressing Network Vulnerabilities: A Deep Dive into Wi-Fi Protected Access In the complex and ever-evolving world of network security, Wi-Fi Protected Access (WPA) stands as a critical line of defense against the myriad threats that target wireless networks. With the proliferation of wireless devices and the increasing sophistication of cyberattacks, ensuring the integrity and confidentiality…

What is network access point? A Network Access Point (NAP) is a key component in telecommunications and networking, serving as a public exchange facility where Internet Service Providers (ISPs) can connect with one another in peering arrangements. These connections enable ISPs to exchange traffic directly, rather than routing it through a third party’s network, which…

What is a network switch? A network switch is a hardware device that connects devices within a computer network, using packet switching to receive, process, and forward data to the destination device. It operates at the data link layer (Layer 2) of the OSI model and sometimes at the network layer (Layer 3) to incorporate…

In the realm of cybersecurity, safeguarding your network against potential threats is paramount. One of the fundamental measures in ensuring the security of your home or business wireless network is through the use of a WPA2 password. This electronic key acts as a barrier, allowing only authorized computers and devices to connect to your WiFi…

What is Classless Inter-Domain Routing (CIDR)? Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and routing Internet Protocol packets. The main idea behind CIDR is to allocate blocks of IP addresses to organizations based on their needs, while trying to conserve the remaining IP address space. Some key points about CIDR: It…

What is network microsegmentation? Network microsegmentation is a security technique that involves dividing a network into smaller segments or zones, and applying security policies and controls to each segment independently. Microsegmentation provides granular security at the network level, enabling organizations to isolate critical applications and data from the rest of the network, and to control…

What is PSK in WPA? In the context of WPA (Wi-Fi Protected Access), PSK stands for Pre-Shared Key. It is a security mechanism used in WPA to establish a secure connection between a wireless client (such as a laptop, smartphone, or other Wi-Fi-enabled device) and a Wi-Fi access point. When using WPA with PSK, a…
