Security Systems Essay System securities are a vital requirement in computers where a great problem in network security is experienced. There are more complexities in the distribution and array of computer network interconnections. This is usually experienced in different environments. Hence there is the need for having methods of solving the problem of system security. This is done through having a network interruption discovery where attacks are detected and the necessary measures taken into consideration. The three types of computer security protocols discussed in this paper are the Teredo protocol, the HTTP protocol and the SSL and TSL protocols. The security implications of these protocols are discussed in this paper. The computer security protocols are applied in different areas depending on the security protocol. The identification of these protocols provides security concerns where the control of security is required. There is need to reduce protection in depth and permitting for unsolicited traffic in the computer systems security controls (Aquino et al, 2008). Types of Protocol SSL TLS (Secure Socket Layer Transport Layer Security) protocol The Secure Socket Layer is an internet protocol for connections which are done from one indication to the other. SSL offers fortification besides tumbling of the roof space, interfering and counterfeiting. Therefore there is genuineness between the customer and the server since the client is able to institute a protected connection across the internet in order to offer fortification to the broadcasted information (Security Protocol Overview, 1999). Due to the increase in the stipulation of internet and digital information communication, a number of functions and workstations require to send out their information in a protected manner to inaccessible appliances and mainframes. This can be cracked by the use of SSL since it is well premeditated for the purpose in a criterion which is open. There are steps which take place in SSL and they include linking, confirmation between parties and finally, swapping over of the protected data. TLS (Transport Layer Security) is the latest improvement of SSL (Security Protocol Overview, 1999). Refer to figure 1 of the appendix. There is ensured discretion of the data due to the use of tough encryption expertise. There is lucidity substantiation of servers and clientele due to the use of digital credentials. The RSA algorithm used by SSL, it is meant to assist in the safety using autographs as well as digital pervasive. In support of extreme rapid encryption and decryption of data for communication after an establishment of SSL link, the suitable algorithm is RC4 (Security Protocol Overview, 1999). SSL can be used in any situation where protection is required between two computers. It can also be used in cases of clientele server co ordinations, monetary and movement business (Security Protocol Overview, 1999). HTTP (Hyper-Text Transfer Protocol) HTTP offers assistance of the starting point in the system since it proposes the path of origin of standard and persistent information prototype contrast sequence. In HTTP, there are a number of classes which are possible for the collapse of data (Alarcon-Aquino et al, 2005). They are inclusive of standard which involves regular conduct of the system order which involves no bother. Adjustment of trail entails adaptation of the address of a folder in order to make accessibility to impracticable (Embrechts, 1993). The cryptogram introduction requires that there is implantation of malevolent ciphers in the add-on of emails. Cross-site writing (XSS) offers access to the confidential IDs, passwords and usernames from different browser casements which are dynamic simultaneously. Finally, there is the prearranged question lingo (SQL) which provides modification of the catalogue, removing or even plagiarism (Torres, 2003, pp. 8-13). Refer to figure 2 of the appendix. Teredo Protocol This protocol is meant to offer assistance to the client to understand a material in a specific report. Teredo protocol works by channelling IPv4 UDP port for a segment of the system that is only IPv4. There are basic machineries which are consisted in the Teredo structures. The components include clientele, communications and servers (Hoagland, 2008, p. 7). Before the sending of packets to and from remote IPv6 nodes, some tunnel setup communication has to take place. Therefore there are phases which are followed which include, the customer completing the qualification procedure in order to establish the address of Teredo. Secondly, the client has to determine which relay to use for a given IPv6 per node. The afterwards, the packet is sent through the relay (Hoagland, 2008, p. 9). See figure 3 in the appendix Possible attacks Storage based attacks Computer security protocols can have attacks that have the possibility of bringing down the system. The attacks can lead the security system to queue up many packets hence leading the denial of service. This is because the attacks make the legitimate packets not able to be delivered or not able to reach new peers. The security protocol can be attacked by the storage based attacks. The attack holds information from reaching its destination (Hoagland, 2008, p. 24). Relay DOS Delays of information can be experienced when there is a condition of denial of service on a network based relay. If the relay is not available and a packet is send then there is no stipulation for the client for establishing a new relay. However, the peer would not be aware of a relay being used and would then send a packet to the address (Hoagland, 2008, p. 25). Server DOS Services can be denied through a brute force attack on the server processing speed or the band width. If the security qualification of the server has part of it as authentication value, then the computation is necessary in response to every qualification request which is valid (Hoagland, 2008, p. 25). Attack detection In detecting attacks in the computer security protocols the solution should be taken depending on which model is used fro detection. Detection models can be hot based model or network based model. The detection of attacks in computer security protocols depends on the model used. The models used in detecting the attacks in security protocols may either be host based models or a network based models (Aquino et al, 2008). When detecting attacks with hot based models, the interruption/intrusion detection systems (IDS) usually make their decisions based on the information which is obtained from either a single or multiple host systems. In the net work based model the decisions of the IDS are made by first monitoring the traffic in the network which is connected to the hosts. The computer security system protocols are dynamic and changing regularly. This makes it necessary to use an approach that is based on neutral networks. The neutral networks are found to do well in the recognition of pattern, classification and computations of tasks that are parallel. This is why the neutral networks are a collection of extremely interrelated processing elements (Aquino et al, 2008).
