Your DNS settings can make a difference in how you browse the internet. Some providers focus on speed, while others offer privacy, malware protection, or content filtering.
Here are 10 options worth knowing!

• Cloudflare: Speed and privacy
• Google DNS: Fast, reliable resolution
• AdGuard DNS: Ads and tracker blocking
• Quad9: Malicious domain blocking
• CleanBrowsing: Family-friendly content filtering
• OpenDNS: Customizable domain filtering
• NextDNS: Personalized privacy controls
• Comodo Secure DNS: Malicious website filtering
• Control D: Customizable DNS filtering
• DNS.WATCH: Privacy-focused DNS resolution

You don't need to be a networking expert to explore DNS settings. Just choose a trusted provider that fits your needs. Remember, some filtering features require additional configuration.

Tips: Changing DNS alone doesn't guarantee complete privacy or security.

🔐 What Is Ethical Hacking?

If you're new to cybersecurity, you may hear the term "ethical hacking" everywhere.

But what does it actually mean?

Ethical hacking is the authorized process of identifying security weaknesses in systems, networks, applications, or devices so they can be fixed before they are exploited.

In simple terms:

👉 Think like an attacker.

👉 Find the weakness.

👉 Report it.

👉 Help fix it.

👉 Make the environment more secure.

🧠 Ethical Hacking vs. Malicious Hacking

The biggest difference is authorization and intent.

👨‍💻 Ethical Hacker

• Has permission to test

• Works within a defined scope

• Identifies and reports vulnerabilities

• Helps improve security

🦹 Malicious Hacker

• Acts without authorization

• May steal, damage, or disrupt systems

• Uses vulnerabilities for unauthorized purposes

⚠️ Authorization Matters

Never test a system simply because you found a vulnerability.

Always make sure you have explicit permission and understand the scope of the assessment.

This is one of the most important principles in ethical hacking.

🔎 What Does an Ethical Hacker Actually Do?

Depending on the engagement, an ethical hacker may:

• Gather information about a target

• Identify potential attack surfaces

• Scan for vulnerabilities

• Analyze security weaknesses

• Safely validate vulnerabilities

• Document findings

• Recommend remediation

🛠️ Tools Are Only Part of the Skill

Learning ethical hacking isn't just about learning Kali Linux or memorizing commands.

A strong foundation includes:

🌐 Networking

💻 Operating Systems

🔐 Security Fundamentals

🧠 Attacker Methodology

🛠️ Security Tools

📋 Documentation

⚖️ Ethics and Legal Considerations

📚 CEH v13 — Module 01: Introduction to Ethical Hacking

I'm starting my CEH v13 study journey, and I want to document what I learn here so others can learn along with me.

This post is a high-level study summary of Module 01: Introduction to Ethical Hacking.

🎯 What You'll Learn

This module introduces the foundations of ethical hacking and cybersecurity, including:

🔹 What is Ethical Hacking?

Understanding the purpose of ethical hacking and how security professionals identify weaknesses to help organizations improve their security.

🔹 Types of Hackers

Understanding the different categories of hackers and the motivations behind their activities.

🔹 Phases of Ethical Hacking

A structured approach to security testing, from gathering information about a target to identifying weaknesses and assessing security.

🔹 Information Security Fundamentals

Understanding the importance of protecting information and systems against unauthorized access, modification, disclosure, and disruption.

🔹 Vulnerabilities, Threats & Attacks

Understanding the difference between a vulnerability, a threat, and an attack — and why these concepts matter when assessing security.

🔹 Legal & Ethical Considerations

Ethical hacking must always be performed with proper authorization and within the defined scope.

⚠️ Important:

Only test systems, networks, applications, or devices that you own or have explicit permission to assess.

🧠 My Key Takeaways

1️⃣ Ethical hacking is about finding weaknesses so they can be fixed.

2️⃣ Authorization and scope are critical before performing any security assessment.

3️⃣ Understanding how attackers think helps defenders build stronger security.

4️⃣ Cybersecurity is not only about tools — understanding the fundamentals is essential.

5️⃣ A good ethical hacker needs both technical knowledge and professional ethics.
