Permissions are based on what the user or group is allowed to do with the data that they have accessed. This includes the ability to alter, add, or delete data. Usernames, passwords, and encryption keys will be used to limit access to the network and to help the IT team keep track of who has used the network and when. This will help reduce the risk of unauthorized access. Gaining access to the network will be done using IPv4 and Mobile IPv4 (MIPv4) protocols.
The direct data packet generated by Network Layer using information that is stored in a table known as routing table. Routing table is a list available destination which enables the network layer to work with logical
[pic] This is an example of a client/server, as you can see the big computer is the server and all the other computer/devices are connected to the server. A client server can be in a foam of any topology such as ring topology, star topology (shown on the picture above), tree topology, mesh topology as well as a buss topology. All you would need is a server on any topology that you are choosing to
Kostadinov goes on to note that most cyberterrorism actions are generally focused on website sabotage and email blasting. In order to prove that the network breach was a terrorist attack the company would need to provide electronic evidence of these types of information warfare. Information warfare is a term often used interchangeably with cyberterrorism but provides a deeper understanding in the shift of how data has become fundamental to society. As governments, companies and people shift to the use of digital information so have the methods used to attack (Gilmer, 2001). In order to combat this aspect of terrorism, the military have adopted computer forensics as part of their defenses (Vacca & Rudolph, 2011).
The information contained in the wrapper tells computers what kind of data is in the packet, how it fits together with other data, where the data came from and the data's final destination. When you connect with someone on an online game, the information breaks up into packets that travel across the network. Different packets from the same information do not have to follow the same path. That's part of what makes the Internet so robust and fast. Packets will travel from one machine to another until they reach their destination.
Data Protection Act 1998 - The Data Protection Act 1998 controls how the personal information is used by organizations, businesses or the government. Everyone who is responsible for using data has to follow strict rules called ‘data protection principles’. The eight main principles of the data are: 1. They have to be processed fairly and lawfully. (not through taking customer information without their consent).
Discuss technology recommendations to meet the future business direction. Be sure to include a rationale for the security requirements and the business need for each priority. Discuss appropriate policies, regulations and technologies to ensure that field data/information is handled properly and securely when used, processed and transported via a laptop or tablet computer. Where appropriate, your recommendations should align with the vulnerabilities you identified in Q. 3.
Lab 2.1 Exercise 2.1.1 Media - the physical structure from which the signal transmits. Interface - how the computer accesses the media. Signal – how information is transmitted. Pattern – an established format for the signals to be interpreted by the computing device. Timing – synchronization between devices that are communicating so that they each know when the patterns start and end.
Lab 2.1: Connecting Computers Exercise 2.1.1 Media, Interface, Signal, Pattern, and Timing are all necessary to establish a network. Media is needed for the physical structure on which the signal will travel. Interface is needed so the computer can access the media. Signal is the means of transmission such as electrical signal. Pattern is the format for the signals to be interpreted.
It will inform you on how hackers and system administrators used ping sweeps and port scans. While describing some of these notorious computer activities, these techniques will also be shown how system administrators can use to benefit the company. Two techniques that are used to attack a network is ping sweep and port scans. These activities can be used with malicious intent against, as well as, in effort to try to protect a network. Ping sweeps and port scans has been a notorious and yet a useful tool for hackers and system administrators.
