IPsec is often installed on today's IPv4 networks to protect communication over VPN networks. It is used to access VPN, as well as between VPNs. IPv6 transition mechanisms can use this kind of infrastructure to achieve a certain level of protection, even in the absence of IPv6 IPsec. Remote IPv4 hosts access private networks by establishing encrypted VPN access to a gateway device set up for this purpose. If the same host is capable of IPv6, it can break through an IPv6 tunnel over this IPv4-protected communication channel.…
is a software-based protocol that provides a way to locate files, devices or even individual in a network. LDAP uses port 389 and is uses by Microsoft as the main protocol that opens up this type of access. LDAP is lightweight which indicates a smaller version with a smaller code and it is part of X.500. The latter acts as a standard for network directory services. /***************************…
VPN A virtual private network is used by organisations to help secure data on a network. It’s very hard to access these private networks meaning that the data becomes much more secure and it can be used across a large area of a network, including many computers. This isn’t an expensive thing to do anyone can do it by using simple publicly available infrastructures. VPN also makes use of encryption firewalls and authentications services when sending data across the web.…
In this task I will be using a diagram to outline the relationship between the layers in an interface showing each other of the points in the corresponding layer in the TCP/IP protocol suite. I will also be describing the type and functions of entities and the service they provide. A) The way communications are done between a computers on a network is through protocol suits. The most used protocol suite and commonly available protocol suite is TCP/IP protocol suite.…
RQ 1 A function for one block of bits in a hash function is referred to as a compression function. RQ 2 The main arithmetic and logical functions in SHA algorithms include AND, OR, NOT, XOR and the circular shift. RQ 3…
Certification Authority(CA):A certification Authority which is having private and public key pairs and trusted by sensors. The role of the CA in this process is to guarantee that the individual granted the unique certificate is in the fact who he or she claims to be. External Agent(EA):External Agent is an entity who tries communicate with the WSN.External agent agent also has a private and public key pair and the public key must be certified the CA.…
So the previous section was discussing the findability Layer which enables humans and applications to search and find the smart thing's services they need, however in this section the main concern is to know more the next layer which is sharing layer. This layer’s main concern is to keep human and machine updated with the new information so the main concern was making this communication secure and free from hacks so researchers tried to use already existing protocols like HTTP that is already provides authentication mechanisms for securely sharing resources by which it allows clients to provide their user names and passwords in order to make HTTP request on a server and it is followed with SSL/TLS in order to make sure that the user names and…
Many Know that the Canadian army is small but the victories and impression we have left will be forever remembered. "We have long said that when Great Britain is at war, we are at war; to-day we realize that Great Britain is at war and that Canada is at war also" – Wilfred Laurier. Our involvement in WWI was based off Britain going to war against Germany. Vimy Ridge is what turned heads during WWI, showing our militaries prowess. Canada’s amount of raw materials Canada that we exported to Britain played a massive part in the allied success.…
Homeland Security Last class period, we had the honor to have an Atlanta police officer come to our class and speak about the importance of homeland security. Homeland security is important especially after 9/11 when America was under attack by terrorist and left millions of Americans afraid to go to the airport. The American government knew that it had to protect its citizens so it created the patriot act, which protected against terrorism and domestic and foreign affairs. Homeland security has the important task to watch out for citizens who want to behave in criminal behavior against the government or who wants to overthrow the government. Groups such as Isis and the Muslim brotherhood are terrorist groups that started in the Middle East,…
This includes shredding all paperwork that contains unnecessary confidential health information, checking the fax number before sending confidential information by fax, using closed door and privacy curtains when discussing health information with a client, and keeping medical records attended to at all times. Confidential health information that you see or hear yourself must be kept to yourself and look only at that medical information you need to do your particular job. If employees come to the healthcare facility for care, their information needs to be as protected as anyone else’s medical records. Security safeguards need to be in place at all times. Some ways to do this include the following: *…
It also keeps a record of any problems and action that may need to be taken. Also that we need to record if there are any kind of factors that will affect the service user. This also has a purpose to make sure we are accurate in whatever we write down, and anything that happens should be noted down as soon as an even has happened. It needs to be dated, timed and signed. Provide clear evidence of the care planned, decisions made, care delivered and information shared.…
Introduction Every other day on the news we are seeing a new tragedy has happened in our country. It is being perpetrated by Muslim extremists or terrorists. Whichever term you prefer, our enemies are coming at us from within the borders of our nation. Homeland Security has taken on a new meaning since 9/11 and we are in a full sprint to keep up with everything happening.…
Lab 2: OSI Model Introduction: This lab expanded upon the first, by outlining in greater depth, the Open Systems Interconnect (OSI) Reference Model. In particular, we covered how this model shapes and forms the key structure of all computer network communication. Covered in the first lab, the layers involved are physical, data link, network, transport, session, presentation and application. The lab portrayed the flow information traffic as movement through a series of ports, similar to entering doors of houses owned by other people.…
Dumb Things Are Important Hello. I think you're pretty neat. Thank you for stopping by.…
As computers became essential to business, industry, trades, and professions, educators and parents became increasingly concerned that young people acquire at minimum the basic understanding of computers and master the related skills. 2. Explain computer algorithms and its significance An algorithm is a set of instructions designed to perform a specific task. In computer science, an algorithm is a set of steps for a computer application to accomplish a task.…
