✅ Cybersecurity Basics

Cybersecurity is all about protecting systems, networks, and data from attacks. The goal? Keep confidentiality, integrity, and availability intact.

Core Pillars
- Confidentiality: Data stays private
- Integrity: Data stays unchanged
- Availability: Systems stay online

Common Attack Types
- Phishing: Fake emails or messages to steal passwords or OTPs
- Malware: Malicious software like viruses, worms, trojans, and ransomware
- Brute Force: Repeated password attempts targeting weak passwords
- Man-in-the-Middle: Attacker intercepts communication, often on public WiFi
- Denial of Service: Flooding a server with traffic to crash websites

Basic Networking Concepts
- IP address: Unique system identifier (e.g., 192.168.1.1)
- DNS: Converts domain names to IPs (e.g., example.com to IP address)
- HTTP vs HTTPS: HTTP sends data in plain text, HTTPS encrypts data using SSL/TLS
- Ports: Entry points for services (e.g., 80 for HTTP, 443 for HTTPS, 22 for SSH)

Security Fundamentals
- Firewall: Filters incoming and outgoing traffic
- Encryption: Protects data in transit and storage (e.g., AES, RSA)
- Hashing: One-way data conversion for passwords (e.g., MD5, SHA-256)

OWASP Basics
- OWASP lists top web risks: SQL Injection, Cross Site Scripting, Broken authentication, Security misconfiguration

Beginner Mistakes to Avoid
- Reusing passwords
- Ignoring updates
- Running tools without understanding
- Skipping networking basics

✅ Cybersecurity Basics: Part 2 - Networking Fundamentals

Why networking matters
• Every attack travels through a network
• You fail faster without this knowledge
• Most security tools rely on packets and ports

Internet flow in simple steps
• You type a website
• DNS resolves domain to IP
• Browser opens a connection
• Server sends response
• Page loads

IP address
• Unique identifier for a device
• IPv4 example: 192.168.0.10
• IPv6 exists due to IP shortage

Public vs private IP
• Public IP faces the internet
• Private IP stays inside network
• Private ranges:
– 192.168.x.x
– 10.x.x.x
– 172.16.x.x

DNS
• Phonebook of the internet
• Converts name to IP
• Attack angle: DNS spoofing

HTTP vs HTTPS
• HTTP sends data in plain text
• HTTPS encrypts data
• HTTPS uses SSL/TLS
• Always secure login pages

Ports
• Logical entry points
• One IP hosts many services
• Common ports:
– 21: FTP
– 22: SSH
– 80: HTTP
– 443: HTTPS
– 3306: MySQL

TCP vs UDP
• TCP: Reliable, used for web, email
• UDP: Faster, used for video, gaming

Packets
• Data breaks into packets
• Each packet has source and destination
• Attackers sniff packets

Firewalls
• Gatekeepers of network
• Allow or block traffic
• Based on IP, port, protocol

Proxy
• Middleman between user and internet
• Hides real IP
• Used in monitoring and bypassing

VPN
• Encrypted tunnel
• Protects data on public WiFi
• Still trust provider carefully

Tools you must practice
• ping: Check reachability
• traceroute: Track packet path
• netstat: View connections
• nslookup: Test DNS

Common beginner mistakes
• Skipping subnet basics
• Memorizing ports without use
• Running scans blindly

What you should do next
• Draw network diagrams daily
• Practice commands on your system
• Capture packets using Wireshark
• Understand one protocol deeply

Encryption and hashing you must understand. ✅

Why this topic matters
- Protects data in transit and storage
- Weak crypto breaks entire systems
- Many breaches start with poor implementation

Encryption vs hashing
- Encryption: Two way
- Hashing: One way

Encryption basics
- Symmetric encryption:
- Same key for lock and unlock
- Fast
- Used for bulk data
- Example: AES
- Asymmetric encryption:
- Public and private key pair
- Slower
- Used for key exchange
- Examples: RSA, ECC

Where encryption is used
- HTTPS traffic
- VPN tunnels
- Disk encryption
- Database encryption

Hashing basics
- Converts data into fixed length value
- One way process
- Same input gives same output
- Common hash algorithms:
- MD5: Broken
- SHA-1: Broken
- SHA-256: Secure

Passwords and hashing
- Never store plain text passwords
- Use salted hashes
- Salt blocks rainbow tables

Real breach example
- LinkedIn lost 117 million hashes
- Used unsalted SHA-1
- Cracked within days

Digital signatures
- Prove authenticity
- Verify integrity
- Used in software updates

SSL TLS explained simply
- Browser verifies certificate
- Public key exchanged
- Symmetric key created
- Encrypted session starts

Common crypto mistakes
- Using MD5 for passwords
- Hardcoding keys
- Reusing encryption keys
- Rolling custom crypto

What you should do next
- Encrypt a file using OpenSSL
- Hash passwords using SHA-256
- Break weak hashes in lab
- Read TLS handshake flow
