• JavaScript: It is the language of the web, which is essential for testing web applications and browsers.
  
• SQL: SQL is a programming language that is used to access, modify, and extract information from relational databases.

3. Learn About Common Attack Vectors

Ethical hackers put themselves in the attacker’s mindset to anticipate their strategies and stay one step ahead. This means understanding the tools, techniques, and procedures (TTPs) that malicious actors commonly use. By thinking like an attacker, ethical hackers can identify and close security gaps before they can be exploited. Here are some common attack vectors employed by malicious actors:

• Compromised Credentials: Weak passwords and phishing attacks can give attackers access to user accounts.
  
• Phishing: Phishing is deceptive emails or messages designed to trick users into revealing sensitive information.
  
• Malware: Malware is malicious software that can steal data, disrupt operations, or take control of systems.
  
• Insider Threats: These threats refer to internal vulnerabilities that a website may be exposed to. For example, disgruntled employees or contractors can pose a significant security risk.
  
• Vulnerabilities: These are weaknesses in software, hardware, or configuration that attackers can exploit.
  
• SQL Injection: SQL injection is a type of cyber attack where an individual injects malicious SQL code into a website to exploit vulnerabilities and gain unauthorized access to a database.
  
• Trust Relationships: Attackers can exploit trusted relationships between systems to gain access.
  
• DDoS Attacks: These attacks overload a system with traffic to make it inaccessible to legitimate users. 

4. Study Network and Security Concepts

The next step in the roadmap for ethical hacking is understanding how networks function. You must familiarize yourself with network protocols as well as the different types of network security controls. You must also learn how these elements interact to create a secure environment. Let’s understand some of these concepts in more detail:

• Principles of Computer Networking: As a professional ethical hacker, you must learn how data travels across networks and different network topologies. And also understand how essential protocols like TCP/IP and DNS function.
  
• Network Security: Exploring concepts like firewalls, intrusion detection/prevention systems (IDS/IPS), and encryption methods used to safeguard networks will enable you to protect sensitive data from attackers.
  
• Different Security Protocols: It is important to understand different security protocols such as SSH, HTTPS, and VPNs. They are responsible for establishing secure communication channels between devices and help protect sensitive information from unauthorized access. 

5. Learn to Assess Threats in Web Applications and Databases

Web applications and databases are prime targets for attackers, so a thorough understanding of their vulnerabilities is crucial for ethical hackers. Let’s take a look at some of the tools to assess vulnerabilities in web applications and databases:

• SQL Injection: It helps in learning how attackers can inject malicious SQL code into web forms to manipulate databases.
  
• Cross-site Scripting (XSS): This helps in exploring how attackers can inject malicious scripts into websites to steal user data or redirect them to phishing sites.
  
• Cross-site Request Forgery (CSRF): It assists in understanding how attackers can trick users into performing unauthorized actions on a website they’re already logged into.

6. Gain Proficiency in Ethical Hacking Tools

Ethical hackers have a diverse arsenal of tools at their disposal to scan for vulnerabilities, exploit weaknesses, and analyze security posture.
