Information Gathering

The first step in ethical hacking is gathering information about the target system. This stage, known as reconnaissance, involves collecting data such as IP addresses and network configurations. The goal is to understand the target’s structure and weak points.

There are two types of reconnaissance: active and passive. Active reconnaissance involves directly interacting with the target, while passive reconnaissance gathers information without direct interaction. Both methods help ethical hackers prepare for the next steps.

Information gathering can be achieved through various tools and techniques. Examples include using search engines, social media, and public databases. The information obtained will guide the subsequent phases of ethical hacking.

Scanning and Detection

After information gathering, the next step is scanning the target system for vulnerabilities. Ethical hackers use tools like Nmap and Nessus to scan for open ports, services, and weaknesses. This phase allows them to identify potential entry points for an attack.

Scanning can be divided into two main categories: network scanning and system scanning. Network scanning checks for open ports and active devices, while system scanning examines the operating system and applications. Both types are vital for a comprehensive assessment.

The results of the scan are analyzed to pinpoint vulnerabilities that need attention. Ethical hackers use this information to develop strategies for further testing. This step is critical for identifying and prioritizing security issues.

Gaining and Maintaining Access

Once vulnerabilities are identified, ethical hackers attempt to gain access to the system. This step involves exploiting the weaknesses found during scanning. The aim is to assess how deeply an attacker could penetrate the system.

After gaining access, the next goal is maintaining it for further analysis. Ethical hackers need to ensure they can stay within the system long enough to understand the full extent of the vulnerabilities. This step helps create a realistic scenario of what a malicious hacker could do.

Gaining and maintaining access is crucial for providing a detailed security report. By understanding how an attack could unfold, companies can better protect their systems. Ethical hackers offer recommendations to close these security gaps and enhance overall protection.
