Passive methods involve extracting publicly available data from websites, social media platforms, and search engines. Conversely, active techniques entail employing tools like Shodan or Nmap to conduct scans, identify live hosts, and discover open ports. Additionally, the reconnaissance process certified ethical hacker includes footprinting, which involves pinpointing network range, architecture, and critical devices. Interestingly, the origins of reconnaissance date back to the US Navy’s 1837 mission during the Caroline Affair, marking the inception of modern reconnaissance operations.

Scanning

The scanning phase of ethical hacking involves several critical steps that contribute to the assessment of a system’s security. This phase is instrumental in identifying open ports and the services running on those ports, as well as mapping the network architecture to locate potential vulnerabilities. Network scans are conducted to gather comprehensive information about the target system, including the identification of live hosts and active devices within the network. Vulnerability scans play a pivotal role in pinpointing weaknesses that could be exploited. Notably, the scanning phase of becoming an ethical hacker holds immense importance, as it enables ethical hackers to comprehensively evaluate a network or system’s security posture.

Gaining Access

Gaining access to ethical hacking unfolds through a series of essential steps. Initially, vulnerabilities are exploited to gain initial access to the target system. Subsequently, the process involves escalating privileges to acquire higher-level permissions within the system. To maintain persistent access as malicious hackers, ethical hackers establish a continuous presence within the system. An integral aspect of this phase is the documentation and reporting of any vulnerabilities discovered, ensuring the system’s security is upheld. Similar to maintaining a relationship, sustaining access to ethical hacking requires ongoing effort and creativity.

Maintaining Access

In the maintenance phase, ethical hackers employ various strategies to ensure continued access to the target system. These strategies include the creation of secure backdoor access points for re-entry, setting up remote administration tools to maintain control from a distance, installing rootkits to operate stealthily, monitoring user activity to gather information about malicious intent, and implementing file-hiding techniques to conceal files and directories. Like seasoned detectives, ethical hackers skillfully cover their tracks, leaving behind no digital footprints.

Covering Tracks

Covering tracks in ethical hacking aligns with the principle of confidentiality, ensuring that unauthorized access leaves minimal to no trace. This phase of ethical hacking also involves clearing logs to remove evidence of intrusion, utilizing encryption to protect files and communications, and manipulating timestamps to conceal unauthorized access.
