Ethical Hacking vs Penetration Testing

Most users get both technologies as the same they think that doing penetration testing is the actual meaning of ethical hacking.  Here, we are going to elaborate on the basic difference between Ethical Hacking vs Penetration Testing in the following table:

Ethical Hacking Penetration Testing
Ethical Hacking is basically the guideline of hacking the system in an official methodology to track down any potential form of vulnerabilities present in the system. It can be expressed as the authorized set of methods to track down security vulnerabilities, drawbacks, and risks.
It is employed to determine the loopholes and secures the actual hacking and the compromisation of the digital assets of an organization on a real-time basis. This process is very useful as it is being functioned to enhance the corporate defense systems.

Phases of System Hacking

When it comes to the knowledge of the Phases of System Hacking:  There are around 5 particular phases in penetration testing which include the following:

  • Reconnaissance: hugely employed to collect data.
  • Scanning: Utilized to collect additional intelligence on the information.
  • Gaining access: Bears command of one or more network devices to obtain datasets.
  • Maintaining access: Takes some additional datasets from the aimed ecosystem.
  • Covering tracks: Clear footprints of the attack detection.

 

Moreover, we can sincerely understand that there are numerous concepts of hacking like the phase of penetration testing, footprinting, scanning, enumeration, system hacking, sniffing traffic, and so on.

Footprinting

Reconnaissance which is also referred to as Footprinting is highly utilized for collecting all the potential datasets about the target system that could be both active as well as passive.  Moreover, the gathered data is employed to trespass into the particular target system and determine the attack types on the system strictly based on security.

In addition, an abundance of info like domain name, IP address, email id, namespace, geolocation, history, etc. of the website can be encountered in this particular way.

Footprint and Scanning Tools

Several tools are used to gather information such as –

  • Search engines: Yahoo, Bing, DuckDuckGo, Google, Mozilla Firefox, and another search distinguished info searching sites to extract any relevant data.
  • Traceroute: It is dedicatedly utilized to track down a way between the user and the target system on the networks.
  • Crawling: Browse the internet to extract data.
  • Nslookup: Querying DNS server to obtain some info
  • Whois: It is a dedicated lookup of the website to get sensitive details such as email, registration, etc.
  • The Harvester: Utilized to register email and subdomains.
  • Netcraft: A pretty genuine tool to collect datasets about web servers on both server and client sides.

Scanning tools such as –

  • Nmap: A wide variety of scanning toolsare especially utilized for scanning purposes and for searching free ports of the target.
  • Nessus: This scanning tool is employed for finding quick vulnerabilities and loopholes in the ports.
  • Nexpose: Its work is just similar to Nessus.

Penetration Testing/ Exploitation tools such as –

  • MEDUSA: This particular tool is used to acquire authentication services in the target machine.
  • Hydra: This tool is genuinely used to break authentication systems.
  • Metasploit: This tool is generally utilized to exploit the system.

Network scanning

The genuine step of Network Scanning is the second stage of information collection where a malicious actor attempts to do an in-depth research into a system to look for some credible form of datasets.  Moreover, ethical hackers attempt to secure an organization’s attacks by utilizing this network scanning efficiently.  In addition, the particular tools and techniques employed for scanning are as follows:

  • Crafted packets
  • TCP flags
  • UDP scans
  • Ping sweeps

The hackers try to track down a live system utilizing a protocol, blueprint the same network and execute vulnerability scans to search for weaknesses in the system.  Moreover, there are 3 types of scanning present as the following:

  • Port scanning
  • Network scanning
  • Vulnerability scanning

Gaining Access

It is the step where a security analyst tries to intervene in a system and gain the access to its digital assets such as:

  • Password cracking
  • Password attacks

Maintaining Access

In this step, you just need to maintain your access to the compromised system to which you have successfully gained access.  Now, to remain undetected in the network, you just require to safeguard your presence in it.  Additionally, you need to install some hidden infrastructure to keep working through the backdoor open, and for doing that so, you need Trojan horses, covert channels, rootkits, etc.

Covering Tracks

Now, you just need to cover all the traces of the attack you made such as log files, intrusion detection system alarms are eliminated to hide the tracks.  In addition, if you remove all the files and folders produced, alters logs and registry once the malicious threat actors depart the compromised system.  Moreover, one may also use reverse Http shells and ICMP tunnels just in order to cover tracks and traces of attacks performed.

Protecting your system from Hacking

Some varied methodologies that can be employed to tackle malicious actors are described below:

OS Updates
