As of 2020, we all are aware of the security breaches happening to the data within the organization. The organizations are using the LAN network or wifi networks, allowing the employees to access and perform their tasks and operations. To ensure that the organization’s sensitive data is secured, a secured wifi network is necessary. The term Wireless Penetration Testing has then come up to test the wifi networks if they are secure or not using some strategies and methodologies. To gain an in-depth knowledge on the approaches used for penetration testing and Kali Linux, you can undergo a Linux certification training which helps you in nurturing yourself.
The primary focus would be on the exploitation of the vulnerabilities on the wireless gateway. It is important to select the right partner to perform wireless penetration testing. The wireless penetration testing is becoming popular because of the tasks and goals that it aims for. It provides us with a report that helps us understand the data security in the organization. It gives us a clear picture of the data vulnerabilities leading to security threats, helps us in identifying if the network connection is secure or not, gives an analysis to the organization if anything is found to be weak, and has to be modified before it goes wrong. In this blog, we will understand about Kali and Raspberry Pi and their usage in Wireless Penetration Testing.
What is Kali Linux and why is it used?
Kali Linux is a free operating system developed to perform penetration testing and security analytics. Kali Linux is formerly called BackTrack, which is a forensic and security-based distribution. Kali Linux is a combination of 600 Kali Linux tools allowing all the different operations to be performed at a single place.
It is usually called as Kali, a penetration testing platform designed and developed for security assessments, threats, security breaches, etc. Kali is used by attackers and security professionals. Kali is used as it provides its extensive support by providing scalability, support, and stability. These are the aspects that any professional would aspire to view in the operating system allowing them to perform their analysis, auditing, tests, checks, and assessments with security networks.
What is Raspberry Pi and Why is it used?
Raspberry Pi is often considered as the next level of Linux. Raspberry Pi is defined as a low-level credit card device or a computing system that can be integrated with the monitor. It is usually a small device that is plugged into the monitor using an HDMI ( High Definition Multimedia Interface) cable. Raspberry Pi is one of the latest platforms that is used for penetration testing. Though it has to be purchased, it is cheaper and available to all kinds of individuals. Raspberry Pi is used as they are small in size, often called a microcomputer, with all the hardware supported accessories making it more flexible and feasible in penetration testing.
Usage of Kali Linux and Raspberry Pi in Penetration testing:
Kali Linux and Raspberry Pi are incredibly the best platforms to perform the penetration testing allowing the professionals to save the organization from security breaches, attacks, etc. Kali Linux includes many tools within it. These tools are used to perform the security analytics of the wifi networks and assessments to understand and review if the networks are secured. As tools are included in Kali Linux, the security professionals and researchers will make use of these tools, which will help in following methodologies and strategies to perform the penetration testing. Let us have a quick review of the popular tools that help in comprehensive penetration testing.
- Kismet Wireless:
Kismet wireless is one of the most commonly used tools in Kali Linux to perform wireless penetration testing. Kismet Wireless is a multi-platform Wireless LAN Analyser designed and developed to implement all the security features like network detection, intrusion detection, packet sniffing, etc. It is developed with a compatible to work with a wireless card supporting all the different wireless networks like 802.11a, 802.11b, 802.11g, and 802.11n standard based.
Kismet wireless has come up with features that include the following:
- Flexible to handle and record the network logs, often called as Network logging.
- Provides its extensive support for channel hopping
- Developed with the ability and compatibility to run in a passive mode
- Helps in detecting the wireless clients and access points
- Kismet wireless helps in the detection of intrusions at a larger scale.
Aircrack-ng is a software security suite designed and developed with the set of tools to perform the testing of the networks in a highly scalable and compatible way. The software tools help in the detection of insecure networks, threats, packet sniffing, intrusions, etc. It helps in the monitoring of the transmission of the packets in an organized format and hence called organized packet analyzer. This software has come up with the auditing apparatus that every security professional would follow and run their analysis to detect the networks. Let us also know the apparatus that they use to perform security analytics.
- Airdecap-Ng: It helps in decrypting the wireless traffic only when the key is deciphered.
- Aircrack-Ng: It helps in the decryption of the passwords used by the employees or individuals. It is also flexible to utilize the statistical techniques to decipher WEP.
- Airmon-Ng: This helps in converting the wireless card into a promiscuous wireless card.
- Aireplay-Ng: It helps in accelerating or generating the traffic at an access point.
- Airmon-Ng: It is mainly used in deciphering passwords, allowing the capturing of the packages of different required specifications.
Aircrack-ng is also developed with multiple features making it the best software suite in the market. Few of the features are listed below:
- Provides its extensive support to all the different standard passwords like WEP, WPA/WPA2-PSK passwords
- Helps in packet sniffing
- It is developed with the ability to create a virtual tunnel.
- It is designed with the feature of password list management, allowing to manage the different passwords.
- It helps in faster WEP and WPA password decryption.
Security is one of the primary aspects which every organization focuses on. If there is no security to the sensitive data using secured networks, it will lead to security attacks allowing the attackers a big way to steal our data. Wireless Penetrating testing has to be performed on all the wireless networks to prevent the organization from Security attacks. I hope this blog has given you an idea of how wireless penetration testing is done. With the latest advancements, the protection of sensitive data is becoming a tedious task, paving a way for many individuals to look into a career path of security roles. Learn more about Linux and it is worthy.
