ASIS is an advanced, professional tool for analyzing, debugging, maintaining and monitoring local networks and Internet connections. ASIS is a network protocol analyzer or sniffer. It captures the data passing through your dial-up connection or network Ethernet card, analyzes the data and represents it in a readable form. ASIS is an useful tool for network administrators, security specialists, network application developers and all those who need a comprehensive picture of the traffic passing through their network connection or a segment of a local network.
ASIS presents the results of its work in a convenient and understandable form. It also lets you defragment and assemble network packets into flows. With ASIS you can easily analyze traffic based on different Internet protocols. ASIS completely decodes all the major protocols such as ARP, IP, TCP, UDP, ICMP, as well as top-level protocols such as HTTP, SMTP, POP, IMAP, FTP, TELNET and others.

The flexible system of filters can discard all network traffic but those traffic patterns you are interested in analyzing. ASIS also contains a special packet builder, through which you can build your own network packets and send them onto the network. This can be used, for example, to check your network for robustness against attacks and intruders.

ASIS requires Windows 95/98/ME/NT/2000/XP and a network connection, which could include any wireless connection or modem that is supported by the NDIS standard.
