Network Security Assessment Network Security is a very dynamic and technical field dealing with all aspects of scanning, hacking and securing systems against intrusion. It is more than just encrypting user data, virtual private networks or installing firewalls. Network security consists of the provision, policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources (Xie, 2013). Network
To allow the regional offices to pass traffic securely a GRE IPsec tunnel will be created between offices. This will allow all data to be encrypted prior to being sent out to the internet. This will prevent unauthorised reading or manipulation of sensitive data. The UK office will have two tunnels, one to each branch office. In order for the remote branches to communicate with each other their traffic will pass through the head office. The initial part of the configuration is the addition of GRE
QUESTION 1: What kind of IP address is this? Can you use this address on the Internet? Why or why not? It is a class C IP address. Because it is a local IPv4 address and not a public IPv4 address, it cannot be used on the Internet. QUESTION 2: Instead of assigning a permanent IP address to PDC-VM, we could let PDC-VM obtain a dynamic IP address. Would that be a good idea? Why or why not? It would not be a good idea, it would be important to always know the IP address of the Primary Domain Controller
Internet Legislation and the Loss of American Freedom SOPA, PIPA, and CISPA: though different, these bills were all presented with a similar goal in mind. These bills were intended to stop the digital copyright infringement of American intellectual properties, mainly in foreign countries, but the overly vague wording in the bills made it hard to decipher their real intentions (Yu). For a multitude of reasons, these bills were staunchly protested not only by American citizens, but they also received
• Source Mac address • Destination Mac address • Source IP address • Destination IP address • TCP port • Action • Count • Stats For firewall to be implemented as application. It is done by the following way, if it is tcp port 25 drop it. It is also possible to use local logic which resides in the remote switch router. This combines both. The other method is, if anything is not matched then forwards the packet to the control plane and it decides and make a decision on the best method to forward
network resources are the base for creating OpenStack Networking component. Similar to a VLAN in the physical networking world, network in OpenStack is an isolated layer-2 segment. Subnet is a block of IP version 4 or version 6 addresses, set as an address pool from which OpenStack can assign IP addresses to virtual machines (VMs). Each subnet is stated as a Classless Inter-Domain Routing range[13]. 2.4.2 Neutron Architecture The main process of the openstack networking component is neutron-server
tool is presented in Figure 1. Virtual computers are generated from real server. The number of virtual computers generated from a real server depends on the scenario under which the DUT[2] is to be analyzed. Each Virtual Computer has a different IP Address. Thus, each virtual computer acts as an individual client. The user (tester) just interacts with the physical computer and executes the python scripts present. These scripts activate the virtual computers which interact with the DUT[2] and generate

connected only. The aspect of having servers located in different places brings the idea of addressing. The internet is structured in a way that to access the different servers, you have to input a certain unique address on the browser you are using. The addressing and naming of that particular address is done by a system generally referred to as the Internet Naming System (Callahan, 2012). This is a system that permits the millions of websites found on the internet today to use normal names that common
In this time where the use of computers and networks related to them has become a common thing, there have been developed problems with concerns about cyber-security. Cyber-security is an important factor to be considered if one is to be able to protect themselves from malicious people and software from the Internet. The majority of the threats to computer networks come from the Internet and they are often intentional, having been developed by people with malicious intent. Cyber security is an attempt
