Chai published on SQL Injection SQL injection is a type of cyber attack that targets the SQL (Structured Query Language) databases used to store data in web applications. In an SQL injection attack, an attacker uses malicious SQL code to manipulate the database behind the web application. This can allow the attacker to access, modify, or delete data stored in the database, and in some cases, take control of the entire database server.
Chai 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.
Chai 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.
Chai 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.
Chai 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.
