Cyber Security- Attacking through Command and Control
Command and Control (C&C) attacks represent one of the most sophisticated and dangerous threats in cybersecurity. These attacks establish a communication channel between compromised systems and attacker-controlled servers, allowing cybercriminals to remotely control infected devices and orchestrate large-scale operations. In a C&C attack, malware installed on victim systems connects back to the attacker's command server, creating a persistent backdoor for receiving instructions. This communication often uses legitimate protocols like DNS or HTTP to avoid detection by security systems. How Command and Control Attacks Work Command and Control Attack Process ...
Read MoreDifference between IP Address and MAC Address
Both MAC Address and IP Address are used to identify a computer on a network or on the Internet. MAC address is provided by the NIC Card's manufacturer and gives the physical address of a computer. IP address is provided by the Internet Service Provider and is called the logical address of a computer connected on a network. Understanding the distinction between these two addressing schemes is crucial for network administration and troubleshooting. What is an IP Address? An IP (Internet Protocol) Address is a unique numerical identifier assigned to every device connected to a network that ...
Read MoreDifference between Static IP Address and Dynamic IP Address
Static IP Address and Dynamic IP Address are two methods used to assign unique identifiers to devices on a network. Static IP addresses remain fixed and are manually configured, while dynamic IP addresses are automatically assigned and can change over time. Understanding the difference between these two addressing methods is crucial for network administrators, web developers, and anyone managing network infrastructure. What is an IP Address? An IP address (Internet Protocol address) is a numerical identifier assigned to each device connected to a network that uses the Internet Protocol for communication. It serves two main purposes: identifying ...
Read MoreHow to Setup HAproxy Load Balance Server for Sharing Web Traffic
This article demonstrates how to configure HAProxy as a load balancer to distribute web traffic across multiple servers, providing high availability and improved performance for web applications. HAProxy is a free, open-source TCP/HTTP load balancer that ensures your website remains accessible even when individual servers fail. Server Setup Overview For this tutorial, we'll configure three CentOS 6.7 servers: HAProxy Load Balancer: 192.168.57.150 Web Server 1: 192.168.57.147 Web Server 2: 192.168.57.148 HAProxy Load Balancer Architecture HAProxy 192.168.57.150 Web Server ...
Read MoreDifference Between Streaming and Downloading
Streaming refers to the process of viewing content held on a remote server in real-time, whereas downloading is the process in which all data is transferred completely to your device before it can be viewed. Understanding the difference between these two methods of content delivery is crucial in today's digital landscape, as each approach offers distinct advantages and limitations. What is Streaming? Streaming is the process of viewing content that is stored on a remote system (server) rather than on a client workstation. The content is delivered continuously over the internet and played immediately. ...
Read MoreTraditional TCP
Traditional TCP (Transmission Control Protocol) is a connection-oriented, reliable transport layer protocol that ensures data delivery between communicating devices over wired networks. Operating at Layer 4 of the OSI model, TCP provides complete transport services by breaking data into segments, managing their transmission, and reassembling them at the destination. TCP was originally designed by Vint Cerf and Bob Kahn for reliable communication over stable wired networks. It works in conjunction with the Internet Protocol (IP) to form the TCP/IP protocol suite, which serves as the foundation of modern internet communication. Traditional TCP Data Flow ...
Read MoreDomain Name System (DNS) Zones
The Domain Name System (DNS) Zones are partitions of the DNS namespace that enable distributed administration of domain names. A DNS zone represents a portion of the DNS tree structure that is managed by a specific administrator or organization, allowing for decentralized control over different parts of the global DNS infrastructure. DNS zones solve the scalability problem that would arise if the entire DNS system were managed by a single authority. By dividing the DNS namespace into manageable zones, administrative responsibilities are distributed, and the workload on individual nameservers is reduced. Multiple zones can exist on the same physical ...
Read MoreWhat are the differences between Firewall and Proxy Server?
To begin with, let us learn the concepts of firewall and proxy server, two essential network security components that serve different purposes in protecting and managing network traffic. Firewall A firewall is a security device that provides protection from external networks such as the Internet. It combines software and hardware components to allow, deny, monitor, and block data transmissions occurring between networks based on predefined security rules. Firewalls evaluate network traffic based on factors like IP addresses, port numbers, protocols, and connection states. They defend against external threats by refusing unauthorized requests and connections from potential attackers, ...
Read MoreWhat are the differences between Border Gateway Protocol (BGP) and Routing Information Protocol (RIP)?
Let us learn the concepts of Routing Information Protocol (RIP) and Border Gateway Protocol (BGP), two fundamental routing protocols that serve different purposes in network communication. Routing Information Protocol (RIP) RIP is a distance-vector routing protocol that uses port 520 for communication. It enables routers to share routing information across networks and prevents routing loops through various mechanisms. Hop count metric − RIP determines the best route using hop count as its primary metric Maximum hop limit − RIP allows a maximum of 15 hops; networks requiring more than 15 hops are considered ...
Read MoreWhat is a Network and process of Network Communications?
A Network is a connection of two or more computer systems that enables sharing of resources, data, and communication services. Networks form the backbone of modern computing, allowing devices to exchange information and collaborate efficiently. Network Communication Process Network communication is the flow of information between connected devices following established protocols and procedures. When a device wants to communicate, it packages data into standardized formats, addresses it to the intended recipient, and transmits it through the network infrastructure. Network Communication Process Source ...
