In today’s digital landscape, cybersecurity is more critical than ever. With increasing cyber threats, data breaches, and privacy concerns, individuals and businesses must take proactive steps to secure their data. This guide outlines the most effective security practices for 2025. 1. Implement Strong Authentication Measures Passwords alone are no longer sufficient to protect sensitive accounts. Instead, consider: ✅ Multi-Factor Authentication (MFA): Require users to verify their identity using an additional factor, such as an SMS code, authenticator app, or biometric authentication. ✅ Passkeys & Password Managers: Use passkeys where available and store strong, unique passwords in a secure password manager. 2. Encrypt Sensitive Data Encryption ensures that even if data is stolen, it remains unreadable without the decryption key. 🔹 Use end-to-end encryption (E2EE) for messages and emails. 🔹 Encrypt stored data on cloud services, external drives, and local machines. 🔹 Consider ...

Cypress provides various functions and commands for writing automated tests effectively. Below is a categorized list of the most commonly used Cypress functions with explanations and examples. 1. Visiting and Navigating Pages cy.visit(url)      Navigates to a specific URL.      cy. visit ( 'https://example.com' ); Can also pass options like authentication headers.      cy. visit ( 'https://example.com' , { auth : { username : 'user' , password : 'pass' } }); cy.go()      Navigates forward or backward in browser history.      cy. go ( 'back' ); // Go back one page      cy. go ( 'forward' ); // Go forward one page      cy. go (- 1 ); // Equivalent to back      cy. go ( 1 ); // Equivalent to forward cy.reload()      Reloads the current page.      cy. reload ();      cy. reload ({ force : true }); // Forces reload, bypassi...

When writing SQL queries, understanding the execution order is crucial for writing efficient and optimized code. Many beginners assume that queries execute in the order they are written, but in reality, SQL follows a specific sequence of execution. SQL Execution Order SQL queries run in the following order: 1️⃣ FROM + JOIN 2️⃣ WHERE 3️⃣ GROUP BY 4️⃣ HAVING 5️⃣ SELECT (including window functions) 6️⃣ ORDER BY 7️⃣ LIMIT Let’s break down each step with examples. 1. FROM + JOIN (Data Retrieval) The SQL engine first retrieves data from the specified table(s) and applies any JOIN operations. 🔹 Example: SELECT employees.name, departments.department_name FROM employees JOIN departments ON employees.department_id = departments.id; Here, the JOIN happens before any filtering ( WHERE ) or grouping ( GROUP BY ). 2. WHERE (Filtering Data) Once data is retrieved, the WHERE clause filters rows before aggregation occurs. 🔹 Example: SELECT * FROM employees WHERE salary > 50000 ; Thi...
