Four Terms associated with the Security management in an Organization;

Asset: Asset is the anything in an Organization that must be protected, or we can define the Assets as the Valuable thing of the Organization which must be protected at any cost, We can define assets in the other way like, THE THING WHICH IS EVERYTHING FOR AN ORGANIZATION THAT MUST PROTECT AT ANY COST

Countermeasure: It is the protection that destroy or mitigate the potential threat

Hey guys, Do you know what DHCP does ? Why do we need DHCP server and What DHCP provides us ? These are the basic things that we must know before configuring the DHCP server in CISCO router. Let’s dig down in our topic

DHCP: DHCP is the Dynamic host configuration protocol, It works at the application layer of the OSI model. The main function of DHCP is to dynamically assigned the IP address to the HOST machine and to eliminate the IP address conflict between the host machine  in the internetwork. So keep in mind, DHCP has mainly two purposes

  1. Assign IP address Dynamically to host machine
  2. Eliminate the IP address Conflict between the host machine in the network

Besides, above two purposes DHCP also provide many configuration to host machine which are following

  • Assign Default Gateway Address
  • DNS server  address
  • WINS server address
  • Subnet mask of the network where the host machine resides

After knowing some of the basic idea about DHCP server, it’s time to configure the DHCP server in CISCO router, to configure the DHCP Server, we generally consider the GENERIC CISCO router (1841 894 ) any series of router

Let’s go, our prime function is to draw simple network topology and configuring the DHCP server in the cisco router, the topology that we are going to use  is right just below.

DHCP configuration Topology
