In computer networking, Cisco ASA 5500 Series Adaptive Security Appliances, or simply Cisco ASA, is Cisco's line of network security devices introduced in May 2005. [1] It succeeded three existing lines of Cisco products: Cisco PIX, which provided firewall and network address translation (NAT) functions, ended its sale on July 28, 2008. [2]
MARS centrally aggregates logs and events from a wide range of popular devices: network devices (such as routers and switches) security devices and applications (such as firewalls, intrusion detection systems vulnerability scanners, and antivirus software) hosts (such as Microsoft Windows, Sun Microsystems Solaris, and Linux syslog)

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.
After collecting the information it will send back the raw data encapsulated in an SNMP protocol. MRTG records this data in a log on the client along with previously recorded data for the device. The software then creates an HTML document from the logs, containing a list of graphs detailing traffic for the selected devices in the server.
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.
Cisco 6509 switch with four line cards and dual supervisors. The Cisco Catalyst 6500 is a modular chassis network switch manufactured by Cisco Systems from 1999 to 2015, capable of delivering speeds of up to "400 million packets per second". [1] A 6500 comprises a chassis, power supplies, one or two supervisors, line cards, and service modules.
System integration is defined in engineering as the process of bringing together the component sub-systems into one system (an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality) and ensuring that the subsystems function together as a system, [1] and in information technology [2] as the process of linking together different computing ...
