testing. The first step in the hacking process is to perform an IP host discovery and port/services scan (Step 1: Reconnaissance and Probing) on a targeted IP subnetwork using Zenmap GUI (Nmap) security scanning software. The second step in the hacking process is to perform a vulnerability assessment scan (Step 2: Scanning) on the targeted IP subnetwork using Nessus vulnerability assessment scanning software. Finally‚ the third step in the hacking process (Step 3: Enumeration) is to identify information

layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs (VLANs) defined at the access layer. VLANs allow you to segment the traffic on a switch into separate subnetworks. Distribution layer switches are typically high-performance devices that have high availability and redundancy to ensure reliability. Access - The access layer interfaces with end devices‚ such as PCs‚ printers‚ and IP phones‚ to provide access

network consists of 383 hierarchically organized regions spanning cortex‚ thalamus‚ and basal ganglia; models the presence of 6‚602 directed long-distance connections; is three times larger than any previously derived brain network; and contains subnetworks corresponding to classic corticocortical‚ corticosubcortical‚ and subcortico-subcortical fiber systems. We found that the empirical degree distribution of the network is consistent with the hypothesis of the maximum entropy exponential distribution

1.Introduction Projects or tenders that a company needs to run‚ usually preceded by a plan before it can be executing for further development. Project management can be used for planning‚ controlling‚ and monitoring a project and usually it is conducted by a planner such as Project Manager. Gantt chart is the good way to show the planning of a project. It is easy to understand and update as a project develops. But the networks of a project are not easy to understand if they have critical paths

Also called a "perimeter network‚" the DMZ is a subnetwork (subnet) that may sit between firewalls or off one leg of a firewall. Organizations typically place their Web‚ mail and authentication servers in the DMZ. DMZ is a military term that refers to the area between two enemies. See bastion host and firewall

look at subnetting and say‚ only one additional level? However‚ in large networks‚ the need to divide the entire network into only one level of subnetworks doesn’t represent the best use of our IP address block. Furthermore‚ we have already seen that since the subnet ID is the same length throughout the network‚ we can have problems if we have subnetworks with very different numbers of hosts on them‚ the subnet ID must be chosen based on whichever subnet has the greatest number of hosts‚ even if most

Networks can interconnect with other networks and contain subnetworks. There are four type of network. First‚ star topology. It interconnects many nodes through a central computer system‚ say a server. When sending a message from one node to another node‚ the message must be sent to the server first. The server receives

Reliability Evaluation of Communication Network Considering Capacity and Delay of Transmission Sheikh Mominul Islam Abstract This paper introduces a reliability index Capacity and Delay Related Reliability (CDRR) for communication networks. An algorithm is proposed for evaluating the CDRR. This algorithm needs the binary system states generated by the minimal paths‚ message flow capacity and time delay of these states. A criterion for computing the delay time of the binary system states is also
