Chay published on Web Application A web application is a type of software application that runs on a web server and is accessed through a web browser over a network, such as the internet. It typically uses a combination of server-side scripts (like PHP, Python, or Java) to handle the logic and database interactions, and client-side scripts (like JavaScript) to manage the user interface and interactions. Web applications can range from simple, static web pages to complex, dynamic applications with real-time updates and interactive features.
Understanding the “Couldn’t agree on host key algorithm” Error and How to Fix It When you encounter the error “Couldn’t agree on host key algorithm” while trying to connect to a Linux machine using SSH, it signifies a compatibility issue between your SSH client and the server’s supported host key algorithms.
What are SSH Host Key Algorithms? SSH (Secure Shell) is a cryptographic network protocol that enables secure communication between two systems.
Chay published on What is Wireshark Wireshark is a network packet analyzer that presents captured packet data in detail, serving as a tool to examine network activities, much like how an electrician uses a voltmeter to inspect electrical cables. It is free, open-source, and widely used for network troubleshooting, analysis, protocol development, and education. Wireshark captures traffic from various network media types such as Ethernet, Wireless LAN, Bluetooth, and more. Users can customize columns, set up packet colorization, and adjust column displays to optimize Wireshark for specific analysis needs.
Chay published on What is Web Server A web server is a software application that serves content (such as web pages, images, videos, etc.) to clients (usually web browsers) over the internet or a local network. It uses the Hypertext Transfer Protocol (HTTP) to communicate with clients and fulfill their requests.
Web Server File Structure The file structure of a web server typically refers to the organization of files and directories (folders) on the server that are accessible to clients over the internet or a network.
Chay published on Intrusion Detection System An Intrusion Detection System (IDS) is a security tool designed to monitor network or system activities for malicious activities or policy violations and produce reports to a management station. IDS doesn’t stop anything that it detects instead it only reports it. IDS come in two main types:
Network Intrusion Detection Systems (NIDS): These monitor network traffic for suspicious patterns that may indicate an attack. They are placed at strategic points within the network to monitor traffic to and from all devices on the network.
Chay published on Session Hijacking Session hijacking is a type of cyber attack where an attacker takes control of a user’s session on a computer system or network service. In a typical online session, such as logging into a website or an application, the user’s identity and privileges are verified through a process known as authentication. Once authenticated, the user is granted a session token or identifier, which allows them to interact with the system or service without having to re-authenticate for each action.
Chay published on DoS - Denial Of Service A Denial-of-Service (DoS) attack is a malicious attempt to disrupt the normal functioning of a network, service, or website by overwhelming it with a flood of illegitimate traffic or requests. The goal of a DoS attack is to make a system or network unavailable to its intended users, causing a denial of service.
There are various types of DoS attacks, and they can target different layers of a network stack.
Chay published on Social Engineering Social engineering is a method used by cyber attackers to manipulate individuals into divulging confidential information, providing access to systems, or performing actions that may compromise the security of an organization or individual. Instead of relying on technical vulnerabilities, social engineering exploits the psychological aspects of human behavior.
Human Based and Computer Based Social engineering attacks can be broadly categorized into two main types based on the primary method of manipulation: human-based social engineering and computer-based social engineering.
Chay published on In the context of cybersecurity or networking, “sniffing” refers to the practice of intercepting and inspecting network traffic. The purpose of sniffing is to capture and analyze data packets as they travel across a network. This activity can be performed for various reasons, both legitimate and malicious.
Here are some key points related to sniffing in cybersecurity or networking:
Packet Sniffing: Sniffing involves capturing and analyzing data packets that are transmitted over a network.
Chay published on Malware Malware, short for “malicious software,” refers to any software intentionally designed to cause damage, gain unauthorized access, or disrupt a computer system, network, or device. It encompasses various types, each with unique characteristics and purposes. Here are the major types of malware:
Viruses: Viruses attach themselves to clean files and replicate when the infected file is executed. They can corrupt or delete data and spread to other systems.
Worms: Worms are standalone malware that replicate to spread across networks, often without user intervention.
