Internet Protocol version 4 (IPv4) Security Essay

IPv4 is an end-to-end network model that supports the multicast operation. Multicast operations or communications involve information transfer from one node in as single transmission to multiple receivers within the network. Moreover, it facilitates the broadcasting of multimedia information like videos and audio teleconferences. IPv4 utilizes MAC addresses and IP addresses to send entropy packets within and outside the Local Area Network respectively.For hostage purposes, routers atomic number 18 used in the interconnection of multiple networks to map the IP addresses to relate MAC addresses. IPv4 uses 32-bit addresses that are divided into octets, each octet separated by a period. This gives different address ranges that are used for different purposes. This communications protocol establishes the use of group access controls, router trusts and group center trusts.However, since information is be sent to group users sharing the same address, it becomes challenging to implement encryption standards and authentication infrastructures. Although sharing a public key may amend the situation, it is only successful if the number of receivers is limited (Bachert, 2002). As a result, bit some receivers get error-free transmissions other may not even master the data that has been transmitted. Internet Protocol Security (IPsec) provides a homogeneous security mechanism framework within the IP suite.IPsec offers a security protocols that serve independently from data origin authentication, cryptographic, replay protection and key stand in mechanisms used in protecting explicit applications. To be put into consideration, IPsec depends on the founding of Security Associations (SAs) between the individual hosts involved in render communications. The SAs agree with clear-cut authentication algorithms, security and cryptographic features that the host uses to firm communicate with another host.
