Dsniff
Dsniff is the collection of various tools that are used for penetration testing and network auditing. The tools like dsniff, msgsnarf, mailsnarf, webspy and urlsnarf passively monitor a network of interesting data like files, emails, passwords and many others.
EtherApe
EtherApe is graphical network monitor for UNIX model PCs after etherman. This interactive tool graphically displays network activity. It features link layer and TCP/IP modes. It supports Token Ring, FDDI, Ethernet, PPP, SLIP, ISDN and other WLAN devices.
Web Proxies: Proxies fundamentally assist in adding encapsulation to distributed systems. The client can request an item on your server by contacting a proxy server.
Paros
It is a Java-based HTTP/HTTPS proxy that helps in assessing the vulnerability of web applications. It supports both viewing and editing HTTP messages on-the-fly. It is supported by Unix and Windows systems. There are some other features as well like client certificate, spiders, proxy chaining and many others.
Fiddler
It is free web debugging proxy tool that can be used for any browser, platforms or systems. The key features of this tool include performance testing, HTTP/HTTPS traffic recording, web session manipulation and security testing.
Ratproxy
A passive and semi-automated application which is essentially a security audit tool. It can accurately detect and annotate problems in web 2.0 platforms.
Sslstrip
This tool is the one that demonstrate HTTPS stripping attack. It has the capability to hijack HTTP traffic on the network in a transparent manner. It watches the HTTPS link and then redirect and maps those links into homograph-similar or look-alike HTTP links.
SSL/TLS Security Test By High-Tech Bridge

Rootkit Detectors To Hack File System
This is a directory and file integrity checker. It checks the veracity of files and notifies the user if there’s an issue.
AIDE (Advanced Intrusion Detection Environment)
It is a directory and file integrity checker that helps in creating a database using the regular expression rules that it finds from the config files. This tool also supports message digest algorithms and file attributes like File type, Permissions, Inode, Uid, Gid and others.
Firewalls: Firewalls monitor and control network traffic. A firewall is the quintessential security tool used by novices and tech experts alike. Here are a few of the best ones for hackers:
Netfilter
Netfilter offers softwares for the packet filtering framework that works within the Linux 2.4.x and later series of kernel. The softwares of Netfilter help in packet mangling including packet filtering along with network address and port translation.
PF: OpenBSD Packet Filter
It is an OpenBSD system that enables filtering of TCP/IP traffic and also performs Network Address Translation. It also helps in conditioning and normalizing of TCP/IP traffic along with packet prioritization and bandwidth control.
