Free Hacking Tools for Penetration Testing
                     Free Hacking Tools for 
Penetration Testing
Penetration Testing is also known as Pen Testing. Pen 
testing is the type of testing a web application, computer 
system, Network to find vulnerabilities that an attacker 
could exploit.
 
It is a practical and accredited way to check the security of 
an IT infrastructure. 
By securely trying to exploit application sensitivities which 
include Operating system service and application 
blemishes, inappropriate configurations, and also perilous 
end-user behavior. 
 
This type of evaluations is also helpful in authenticating 
the efficiency of defensive ways and also end-users’ 
adherence to security strategies.
 
Information about any security susceptibilities collected 
using Penetration testing need to be characteristically 
combined and presented network systems managers to 
perform remedial measures.
Types Of Penetration Testing To Know
         
Internal Testing - 
 
The aim here is to simulate what would happen if a company's own employee attempted to carry out an attack from within. 
Although various companies concern themselves with outside threats, many breaches occur because of someone inside the 
penetration testing service provider itself. 
Internal testing can help businesses recognize weaknesses in their second or third lines of defense, as an insider attack will 
bypass perimeter safeguards altogether.
External Testing - 
 
External testing is perhaps the very used form of penetration testing. Here, QA experts probe application security 
as an external threat might, finding vulnerabilities in everything from firewall protection to domain name 
servers. 
Double-blind Testing - 
 
The advantage of double-blind testing is that it usually catches development teams and IT staff by surprise. In 
various other instances of penetration testing, everybody involved in the software project is aware that the 
app's security is going to be probed.
 
That's not the case here. True double-blind testing includes notifying only the bare minimum number of people 
before being carried out. This way, QA teams can determine how the penetration testing service provider and 
software will actually react in the event of a breach attempt.
Some Tools That Are Available For Free Online That We Highly 
Recommend:
Kismet
 
Category: Packet Sniffer
 
With expanding instances of wireless LAN hacking, Kismet has 
become a powerful tool for identifying intrusion and packet sniffing 
on the 802.11 a/b/g family of WLAN that supports raw monitoring 
(rfmon) mode.  
 
Aircrack-ng
 
Category: Password Cracking
 
Aircrack-ng is a suite of wireless password cracking tools for the 
802.11a/b/g group of wireless networks that supports raw monitoring 
(rfmon) mode. It captures network traffic in monitor mode and once 
sufficient data is captured it runs cracking algorithms to improve WEP 
and WPA keys. 
OpenVAS
 
Category: Vulnerability Scanner
 
OpenVAS is a vulnerability scanner that was forked from the last free version of Nessus after that tool went 
proprietary in 2005. The free version of Nessus today only works in non-enterprise environments. For security 
audit purposes, Nessus remains a popular vulnerability scanner, however, program scans now require a license 
fee of about $3,000 a year.
 Metasploit
 
Category: Vulnerability Exploitation Framework
 
The Metasploit framework implements a series of tools to 
perform penetration testing on a system. This multi-uses 
hacking framework is widely applied by pen testers to 
unearth vulnerabilities on different platforms, collect 
information on the existing vulnerabilities, and retest the 
remediation defenses in place.
 
 Fiddler
 
Category: Proxy Server Application
 
Fiddler is a freeware web proxy tool that is browser and 
platform agnostic. It has several features that can help a 
pen tester. It allows users to debug web traffic from any 
system (works with almost all operating systems on PCs), 
smartphone, or tablet.
