Ethical Hacking and Network Defense Basics
The ethical hacking process
The ethical hacking process is a systematic approach to conducting a security assessment of a system or a network. It consists of five phases:
Phase
Description
Planning and scoping
This phase involves defining the scope, objectives, and rules of engagement of the ethical hacking project. It also involves gathering information about the target system or network, such as its architecture, components, services, users, and policies.
Reconnaissance
This phase involves collecting more detailed information about the target system or network, such as its IP addresses, domain names, open ports, running services, operating systems, applications, vulnerabilities, and security controls. This phase can be performed actively or passively.
Scanning
This phase involves verifying and validating the information gathered in the reconnaissance phase. It also involves identifying more vulnerabilities and weaknesses in the target system or network. This phase can be performed using various tools and techniques, such as port scanners, vulnerability scanners, network mappers, packet sniffers, and protocol analyzers.
Exploitation
This phase involves exploiting the vulnerabilities and weaknesses found in the scanning phase. It also involves gaining access to the target system or network, escalating privileges, maintaining persistence, and executing commands. This phase can be performed using various tools and techniques, such as exploit frameworks, shellcode generators, password crackers, rootkits, backdoors, and trojans.
Post-exploitation
This phase involves performing further actions on the compromised target system or network, such as exfiltrating data, installing malware, deleting logs, covering tracks, pivoting to other systems or networks, and launching denial-of-service attacks. This phase can be performed using various tools and techniques, such as file transfer tools, keyloggers, spyware, ransomware, botnets, and flooders.
Analysis and reporting
This phase involves analyzing and documenting the results of the ethical hacking project. It also involves presenting the findings and recommendations to the system or network owner. This phase can be performed using various tools and techniques, such as report generators, presentation software, charts, graphs, tables, and diagrams.
