I.  Introduction to Become an Ethical Hacking Pro

Understanding the Concept of Ethical Hacking

Penetration testing, commonly referred to as ethical hacking or white-hat hacking, is the systematic probing of computer systems, networks, applications, and devices to find security flaws.  In addition, they perform several activities with the permission of the system’s owner or organization to enhance the security posture of varied IoT devices comprised of the IT infrastructure.

The Importance of Ethical Hacking in Today’s Digital Landscape

In the modern digital environment, ethical hacking is essential to maintaining the security and reliability of computer networks, information systems, and data.  The importance of ethical hacking has substantially increased as technology develops and permeates more areas of our life.  In today’s digital environment, ethical hacking is essential for the following reasons:

• Identifying Vulnerabilities,
• Strengthening Cybersecurity Defenses,
• Protecting Sensitive Data,

III.  Understanding Common Cybersecurity Threats

Overview of Cybersecurity Threat Landscape

The variety of threats, dangers, and weaknesses that are present in the digital world are referred to as the cybersecurity threat landscape since they are dynamic and always changing.  It refers to a range of destructive actions and assaults carried out by online criminals to take advantage of flaws in software, networks, and computer systems.  As new technologies are developed, the threat landscape is continuously shifting, and hackers modify their strategies to capitalize on these advancements.

Types of Cyber Attacks Explained

Here are the main types of Cyber Attacks:

Phishing Attacks	Phishing attacks entail duping people into divulging private data, like login credentials, credit card information, or passwords.
Malware Attacks	Viruses, worms, Trojan horses, ransomware, and other dangerous software are all examples of malware, often known as malicious software.  Malware is made to hack into systems and compromise them, steal data, sabotage operations, or demand money from unwitting victims.
DDoS Attacks	DDoS attacks flood the targeted network architecture or servers with excessive traffic, rendering services inaccessible to authorized users.
Ransomware Attacks	A form of software known as ransomware encodes the data of a victim or locks them out of their computers and then demands payment in exchange for the decryption key or to regain access.
Social Engineering Attacks	Utilizing social engineering techniques, individuals are tricked into taking specific activities or disclosing private information.
Insider Threats	Insider threats are assaults or security lapses started by someone working for a company who has possession of confidential data and use that access maliciously.

IV.  Reconnaissance and Footprinting

The earliest stages of hacking involve reconnaissance and footprinting, during which attackers learn as much as they can about a target system, network, or organization.  Identifying the intended victim’s weaknesses and possible entry points during these stages is essential for the attacker to better effectively plan their assault.  In the case of ethical hacking, reconnaissance, and footprinting are carried out by security experts with the owner’s consent to find and proactively fix security flaws.

Moreover, there are two types of Reconnaissance:

• Active Reconnaissance,
• Passive Reconnaissance.

Apart from reconnaissance, there are 4 types of footprinting tactics:

• Network Footprinting,
• Website Footprinting,
• People Footprinting, and
• Competitive Intelligence.

V.  Scanning and Enumeration

Following reconnaissance and footprinting, scanning, and enumeration are essential phases in the ethical hacking procedure.  In these stages, the target system or network is aggressively probed to learn more specifics regarding its open ports, services, and potential weaknesses.  Scanning and enumeration are tools used by ethical hackers to find vulnerabilities and potential entry points, such as the following:

There are 4 types of scanning examples:

• Port Scanning,
• Network Scanning,
• Vulnerability Scanning, and
• Banner Grabbing.

Moreover, 3 types of Enumeration are there, as mentioned below:

• Service Enumeration,
• User Enumeration,
• Network Enumeration, etc.

VI. Vulnerability Assessment and Penetration Testing (VAPT)

In general, vulnerability assessments give a complete overview of the security posture of the firm by looking for identified weaknesses and configuration errors.  Penetration testing, on the other hand, goes further by actually exploiting flaws to ascertain the system’s resistance to actual attacks.

Both VAPT processes are essential for firms to identify their safety risks and put in place the necessary safeguards to secure their data and systems.  They work best together.

VII.  Wireless Network Security

Understanding Wireless Network Vulnerabilities

Users may connect to the web and share information without using physical cords because of the simplicity and adaptability that wireless networks offer.  Wireless networks do, however, also offer certain weaknesses that attackers can take advantage of.  In order to successfully secure wireless networks, it is essential to comprehend these vulnerabilities.

1. Preparation,
2. Identification,
3. Containment,
4. Eradication,
5. Recovery, and
6. Lessons learned.

Disaster Recovery:

Business continuity planning, also referred to as BCP, is an element of disaster recovery (DR).  It emphasizes returning an IT infrastructure and systems to operational status following a catastrophe.  Natural disasters (such as a flood or earthquake) or man-made ones (such as a cyberattack or hardware malfunction) both qualify as disasters.  A few essential steps in disaster recovery planning are:

1. Risk Assessment,
2. Recovery Planning,
3. Implementation,
4. Testing and Maintenance,
