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 ...
1. Variables & Data Types x = 10 # Integer y = 3.14 # Float name = "Alice" # String is_active = True # Boolean fruits = [ "apple" , "banana" , "cherry" ] # List person = { "name" : "John" , "age" : 25 } # Dictionary 2. Basic Operations sum = 5 + 3 # Addition diff = 10 - 4 # Subtraction prod = 6 * 7 # Multiplication quot = 10 / 3 # Division mod = 10 % 3 # Modulus power = 2 ** 3 # Exponentiation 3. Conditional Statements x = 10 if x > 5 : print ( "x is greater than 5" ) elif x == 5 : print ( "x is 5" ) else : print ( "x is less than 5" ) 4. Loops # For Loop for i in range ( 5 ): print (i) # 0, 1, 2, 3, 4 # While Loop x = 5 while x > 0 : print (x) x -= 1 5. Functions def greet ( name ): return f"Hello, {name} !" print (greet( "Alice" )) # Output: Hello, Alice! 6. Lists ...
