The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans. [11] Snort can be configured in three main modes: 1. sniffer, 2. packet logger, and 3. network intrusion detection. [12]
Note: Web logging is only supported on hosts running Microsoft IIS on Windows, Apache on Solaris or Linux, or iPlanet on Solaris. [1] Note: Hosts running Microsoft IIS on Windows need to run InterSect Alliance SNARE for IIS, from which MARS receives web log data. [2] network traffic (such as Cisco NetFlow).
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
HOL blocking can produce performance-degrading effects in input-buffered systems. This phenomenon limits the throughput of switches. For FIFO input buffers, a simple model of fixed-sized cells to uniformly distributed destinations, causes the throughput to be limited to 58.6% of the total as the number of links becomes large.
NetFlow is a feature that was introduced on Cisco routers around 1996 that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination traffic, class of service, and the causes of congestion.
Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly.
