The primary difference between SSH and Telnet is that SSH encrypts all communication, providing a secure connection, while Telnet sends all data in plain text, making it highly vulnerable to interception and security attacks. SSH is the modern, recommended standard for remote access, whereas Telnet is largely obsolete due to its security flaws. Comparison of SSH and Telnet Feature SSH (Secure…
Fortinet firewall policies are configured under Policy & Objects > Firewall Policy to control traffic based on source, destination, service, and action (Accept/Deny). Key settings include defining incoming/outgoing interfaces (e.g., LAN to WAN), enabling NAT for internet access, and applying security profiles. Policies are stateful, requiring explicit rules to permit traffic. Fortinet firewall policies are configured under Policy &…
ServiceNow is a cloud-based Platform-as-a-Service (PaaS) that uses AI and machine learning to automate enterprise workflows, specifically for IT, HR, customer service, and security. It serves as a central system of action, connecting disparate departments to streamline processes, improve productivity, and enhance employee and customer experiences. Key Aspects of ServiceNow: Core Functionality: Originating in IT Service Management…
SD-WAN (Software-Defined Wide Area Network) is a virtualized networking approach that uses software to manage and optimize connectivity between geographically dispersed locations, such as branch offices, data centres, and cloud environments Core Components Key Features
Static routing in computer networks is a manual configuration method where network administrators explicitly define the paths for data packets in a router’s routing table. It is a non-adaptive technique ideal for small, stable networks, offering high security, predictability, and low resource overhead because it does not require frequent routing table updates. Key aspects of static…
IPv4 uses 32-bit addresses, supporting ~4.3 billion devices with decimal notation (e.g., 192.168.1.1), leading to address exhaustion. IPv6 uses 128-bit addresses, providing unique, hexadecimal-notated addresses, eliminating the need for NAT, and offering built-in IPsec security, faster routing, and automatic configuration (SLAAC). Key Differences Between IPv4 and IPv6 Routing/Performance: IPv6 uses multicasting and anycast, reducing network congestion….
To access another computer on the same network, enable Remote Desktop (Windows Pro) in Settings, or use File Explorer to navigate the “Network” tab. Ensure both computers have network discovery enabled, are on the same Wi-Fi/Ethernet, and use the target PC’s name or IP address. Common methods include Windows Remote Desktop, Chrome Remote Desktop, or file…
IT incidents are like uninvited guests at a party – disruptive, unwelcome, and demanding immediate attention. But unlike uninvited guests, IT incidents can’t be politely ushered out the door. They require a well-orchestrated response, a dance of swift action and meticulous procedure. Here’s how to tango with IT incidents and emerge victorious. When IT Glitches…
A Layer 2 (L2) switch is a high-speed networking device operating at the Data Link layer (Layer 2) of the OSI model, primarily used to connect devices within a local area network (LAN). It forwards data frames based on destination MAC addresses, using a MAC address table to direct traffic specifically to the intended port, reducing…
A network switch is a hardware device that connects multiple devices (computers, printers, servers) within a Local Area Network (LAN) using Ethernet cables. It operates at Layer 2 (Data Link Layer) of the OSI model, intelligently forwarding data packets only to the intended destination device using MAC addresses, which increases network efficiency and speed. How a…
