Active Directory PenTesting
In today's digital world, cyber attacks are becoming increasingly sophisticated, and organizations must continuously monitor and improve their security measures. Penetration testing, commonly known as pen testing, is a crucial step in identifying vulnerabilities and weaknesses in an organization's systems, networks, and applications. One critical area that needs to be tested is the organization's Active Directory (AD). This article will discuss Active Directory pen testing, why it is essential, and some examples of AD vulnerabilities. What is Active Directory? Active Directory is a directory service developed by Microsoft for managing and organizing information about users, computers, and other resources in ...
Read MoreADD PPP Command in PPP Configuration
Introduction PPP (Point-to-Point Protocol) is a network protocol that allows communication between two devices over a point-to-point connection. It is a widely used protocol for establishing and managing Internet connections over dial-up, DSL, and other types of connections. PPP uses a variety of commands to configure and manage communication session between two devices. One such command is "ADD PPP" command. In this article, we will discuss ADD PPP command in PPP configuration, its significance, and various examples of its usage. What is ADD PPP Command? The ADD PPP command is a configuration command used to create a new PPP session ...
Read MoreFile transfer protocol server configuration using cisco packet tracer
Introduction A File Transfer Protocol (FTP) server is a network protocol that allows users to transfer files between computers over internet or a local area network (LAN). FTP servers are commonly used in businesses and organizations for file sharing and storage. In this article, we will discuss how to configure an FTP server using Cisco Packet Tracer. Setting up FTP server Before configuring an FTP server, we need to have a server machine and an FTP client machine. In this example, we will be using two virtual machines (VMs) on Cisco Packet Tracer, one acting as FTP server and other ...
Read MoreFile Service Architecture in Distributed System
Introduction In distributed systems, file service architecture is an essential component that enables users to access and manipulate files remotely. file service architecture enables multiple users to access a shared file system over a network. This article will explore file service architecture in distributed systems, including its design, components, and examples of implementations. Design of File Service Architecture The design of file service architecture is based on a client-server model. client sends a request to server, and server processes request and sends back requested data. client-server model provides a scalable, fault-tolerant, and reliable file service architecture in distributed systems. The ...
Read MoreFile Accessing Models in Distributed System
In a distributed system, multiple computers work together to provide a cohesive service to users. One of most critical components of a distributed system is ability to access files stored on different computers in network. Different file accessing models have been developed to manage this complexity and ensure efficient and secure file sharing. In this article, we will explore various file accessing models in a distributed system. Centralized File Accessing Model In a centralized file accessing model, all files are stored on a single server or node, and users access these files through server. This model is simple to implement ...
Read MoreFiber Optics Broadband Connection
In today's digital age, high-speed internet is no longer a luxury but a necessity. With growing demand for streaming services, video conferencing, and online gaming, traditional copper-based internet connections are becoming outdated. Fiber optics broadband connection has emerged as go-to solution for reliable, high-speed internet that meets needs of modern-day user. In this article, we will explore what fiber optics broadband connection is, its benefits, and its applications. What is Fiber Optics Broadband Connection? Fiber optics broadband connection is an internet connection that uses fiber-optic cables to transmit data. Unlike traditional copper cables, which transmit data through electrical signals, fiber ...
Read MoreFeatures of Good Message Passing in Distributed System
In a distributed system, message passing is a critical component of communication between processes or nodes. Message passing allows processes to share data, coordinate their activities, and respond to changes in system. A well-designed message passing system can improve performance, reliability, and scalability of a distributed system. In this article, we will discuss features of good message passing in distributed systems and provide examples of how these features can be implemented. Reliability Reliability is one of most important features of message passing in distributed systems. Messages should be delivered to intended recipient, even in presence of failures, network delays, and ...
Read MoreFeatures of Enhanced Interior Gateway Routing Protocol (EIGRP)
Introduction The Enhanced Interior Gateway Routing Protocol (EIGRP) is a widely used routing protocol in computer networks. It is an advanced version of Interior Gateway Routing Protocol (IGRP), which was developed by Cisco Systems. EIGRP is an advanced, distance vector, routing protocol that provides faster convergence and better scalability compared to other distance vector routing protocols. This article will discuss features of EIGRP that make it one of most preferred routing protocols for large networks. Fast Convergence One of significant features of EIGRP is its fast convergence. Convergence is process by which all routers in a network come to agree ...
Read MoreFast Recovery Technique For Loss Recovery in TCP
Introduction Transmission Control Protocol (TCP) is a widely used protocol for data transmission over internet. However, data transmission over TCP is not always error-free. transmission can be disrupted due to several reasons such as network congestion, packet loss, or failure of intermediate devices. In such cases, TCP uses a loss recovery technique to recover lost data and retransmit it. This technique is crucial in ensuring reliability of data transmission over internet. In this article, we will discuss fast recovery technique for loss recovery in TCP. Understanding TCP loss recovery technique TCP uses a three-way handshake mechanism to establish a connection ...
Read MoreExplicitly assigning port number to client in Socket
Introduction When building client-server applications using sockets, it's essential to assign a unique port number to each client to ensure proper communication between server and clients. By explicitly assigning a port number to each client, server can identify and communicate with individual clients without confusion or overlap. In this article, we'll explore importance of assigning port numbers to clients and how to do so effectively. What is a port number? In context of networking, a port number is a 16-bit unsigned integer that uniquely identifies a specific process to which a network packet is directed. When a client sends a ...
