technology, enabling you to capture and import production conditions
directly into network simulation scenarios and test
applications
under real-life network conditions. Network Catchers production network
recordings are also ideal for baselining the performance of the production
network, including best case, worst case and average application
performance giving you a great starting point from which to make informed
decisions on performance limitations and expectations for new or existing
applications that are about to be deployed over the network. Using
production network parameters is ideal for testing applications when the
target network already exists, such as a companys corporate network or a
customers network. However, if the target network has not yet been
designed or built out, you can record a variety of different production
networks and create a library of production network conditions which you
can then use to test your applications and ensure that that they meet
performance expectations in any potential network environment.

| NMAP
The Network Mapper |
nmap is a utility for port scanning large
networks, although it works fine for single hosts. The guiding
philosophy for the creation of nmap was TMTOWTDI (There's More Than One
Way To Do It). This is the Perl slogan, but it is equally applicable to
scanners. Sometimes you need speed, other times you may need stealth. In
some cases, bypassing firewalls may be required. Not to mention the fact
that you may want to scan different protocols (UDP, TCP, ICMP, etc.).
You just can't do all this with one scanning mode. And you don't want to
have 10 different scanners around, all with different interfaces and
capabilities. Thus I incorporated virtually every scanning technique I
know into nmap. Vanilla TCP connect() scanning, TCP SYN (half open)
scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy
(bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses
some packet filters), TCP ACK and Window scanning, UDP raw ICMP port
unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct
(non portmapper) RPC scanning, Remote
OS Identification by TCP/IP Fingerprinting, and Reverse-ident
scanning. |
|
Security Manager Plus |
Security Manager Plus is a network security
