What Is Penetration Testing?
Penetration testing, also known as pen testing, is a means computer securities proficient use to detect and take advantage of security weaknesses in a computer application. These specialists are also known as white-hat hackers or ethical hackers, simplify this by simulating real-world attacks by criminal hackers, who are known as black-hat hackers.
Penetration testing is similar to recruit a hacker to attempt a cybersecurity attack to check the network or application hardness. The results are used by organizations to make their applications or network more secure.
How do Penetration Tests work?
The first step of penetration Testing is Penetration testers to study about the computer systems which they are attempting to breach. Then, they characteristically use a set of computer software tools to find vulnerabilities. Penetration testing may also involve social engineering hacking threats. Penetration Testers try to gain access to a system by trapping an employee of an organization into providing access.
Penetration testers deliver the outputs of their tests to the organization so they can easily make changes either resolve or mitigate the vulnerabilities.
Types of Penetration Tests
Penetration testing can consist of one or more of the following types of tests:
• Blind Tests
A blind test is also known as a black box test in which organizations do not provide any security information about targeted systems. The objective is to reveal vulnerabilities that would not be noticed otherwise.
• Double-Blind Tests
A double-blind test is also known as a covert test, in which the organizations not provide security information to testers and not inform their security teams regarding tests. Double-blind testing is referred to as the gold standard of testing. Such tests are typically highly controlled by those managing them.
• External Tests
An external test is one in which penetration testers attempt to find vulnerabilities remotely, they have performed the test on public-facing applications such as websites.
An internal test is one in which the penetration testing takes place within an organization’s sites. These tests focus on security vulnerabilities that someone working from within an organization could take advantage of.
•White Box Tests
A white box testing is testing in which organizations provide the penetration testers authority and security information relating to their systems to penetrate so they can expose and find the existing vulnerabilities in the systems.

Wireshark offers real-time network analysis. It allows users to view reconstructed TCP session streams. Many prefer Tcpdump for security and system-resource reasons, but Wireshark remains the most popular packet sniffer. The software receives regular updates to outfit its robust packet-sniffing capabilities. Wireshark is very similar to tcpdump, but has a graphical front-end, plus some integrated sorting and filtering options. Wireshark uses pcap to capture packets, so it can only capture packets on the types of networks that pcap supports. Data can be captured “from the wire” from a live network connection or read from a file of already-captured packets. Captured files can be programmatically edited or converted via command-line switches to the “editcap” program and data display can be filtered using a display filter.
