Apr 15, 2013 · Footprinting is the organized research of the Internet addresses owned or controlled by a target organization. The attacker uses public Internet data sources to perform keyword searches to identify the network addresses of the organization. This research is …
Answer : Network fingerprinting yields a network analysis of a set of Internet addresses that can later be analyzed to figure out a way into a system . Footprinting is the initial investigation , …
Network enumeration is a process that involves gathering information about a network such as the hosts, connected devices, along with usernames, group information and related data. Using protocols like ICMP and SNMP, network enumeration offers a better view of the network for either protection or hacking purposes.
Network enumeration tools scan ports to gather information. They may also fingerprint the operating system. All of these are done for the purpose of looking more closely at how a network is set up and how data traffic are handled.
Routers operate at the Network layer (Layer 3) of the OSI networking model. They use source and destination addresses, which are located at the Network layer, to route packets. Switches use MAC addresses, which are located at the Data Link layer, to forward frames. The Data Link layer is Layer 2.
For example, an intrusion detection system (IDS) can monitor real-time traffic on the internal network or a de-militarized zone (DMZ). In a DMZ, public servers, such as e-mail, DNS, and FTP servers, are hosted by an organization to segregate these public servers from the internal network.
An embedded firewall is typically implemented as a component of a hardware device, such as a switch or a router. A software firewall is a program that runs within an operating system, such as Linux, Unix, or Windows 2000. Firewalls can be used to create demilitarized zones (DMZs).
A DMZ can also be implemented with two firewalls. In this configuration, one firewall is connected to a private network and a DMZ segment, and the other firewall is connected to the Internet and the DMZ segment. To implement a firewall, you should first develop and implement a firewall policy.
Explanation: A hardware firewall is also referred to as an appliance firewall. Appliance firewalls are often designed as stand-alone black box solutions that can be plugged in to a network and operated with minimal configuration and maintenance.
Firewalls can be used to create demilitarized zones (DMZs). A DMZ is a network segment placed between an internal network and a public network, such as the Internet. DMZs allow remote access to services while segmenting access to the internal network. Typically, either one or two firewalls are used to create a DMZ.
Explanation: A proxy server acts as an Internet gateway, firewall, and Internet caching server for a private network. Hosts on the private network contact the proxy server with an Internet Web site request. The proxy server checks its cache to see if a locally stored copy of the site is available.
