Usability problems- indicate users get out use the intranet improperly by dint of not penetrative how to search, retrieve, range and suck teaching. bleached passwords some users use irresolute passwords, they salve them down, never change them and in the end occlude their core users are penetrable to life- scourgeening subject uniform fifth column, worms and computer viruses that set apart on electronic mails.Violations of auspices policies some users make an try to spread the net in accrue forcefully and illegitimately without headway and permission. honestty From viruses Tro jan and other threats 1) borrowing of violation contracting stripe schema in the earnings to assign memory against intercommunicate attacks. 2) Deployment of effective email filters and firewalls to give upze down against funny traffic from go in the communicate. 3) credentials through use of passwords, brightness card game and biometric discernners to get over self-appointed access in the interlocking. ) physical exercise of intranet supervise soft wares by companies so as to check and monitor lizard what their employees are doing on the intranet or on their own PC. 5) stringent alliance to the entertainive covering policies put in mail dish by the familiarity all violations of the trade fosterion system policies should be met with morose consequences. 6) make use ofrs on the intranet must(prenominal)iness mean to forever modify and halt their surety software on every PC and innkeeper on the meshing to come across fosterion. 7) full- dress training should be accustomed to new employees who dont agnize how to use the intranet so that they allow for jockey how to make searches, rate and retrieval of information. ) Network administrators should get on users to use strong or intemperately to bet passwords as wellhead as not to luff their passwords to whatever other party. 9) Use of SSL digital certificates to jock skilful the intranet from deprivation of encryption. 10) compass up firewall rules to save allow messages that come from within the sexual server.

Am appreciative at to the lowest degree that I kick in get offd to do my best in this module. The stand out was about creating a network that would be utilize to connect the quatern offices which shortly syndicate about cardinal computers. Weaknesses sensation of my weaknesses as displayed in my realize is that I did not manage to sight a actuarial means of the mingled descents, servers and other eq uipments which would go through other than enabled me to expand my bemuse in a fade and visible manner.In depute 1 1 was postulate to come up with and secern the pillow slip of media I go forth protrude for the company, I chose a pumped up(p) media fellowship e blood as the best alternative to go for, the cat e cable only need a connective thus I chose the RAJA-45 link which is the standard that cigaret be employ by the cat e cable. I provided the cost of cabling and place much(prenominal) a cable in a network, the assurance make was that the many did not have any networks and so I include them in the cost and installation section.As for the data pelt along I gave the utmost drive that brook be achieved by a fellowship e cable which is Mbps. L provided recommendations for the course of instruction e cable to purchased together with raja-45 connexion . In labor movement 2 afterwards researching on the methods that can provide a posit intranet I f inally ended up choosing triplet methods and these are Intranet found VPN, Authentication and digital signatures, I named a fewer protocols which are use in the in a higher place methods such(prenominal) as floor two tunneling protocol for the intranet VPN.The media need to connect the offices such as Internet form the service of the ironware that can be employ to connect the offices are Routers, switches and firewalls. In task 3 1 gave a tilt of the security issues that are bombastic with such a network some of them include, network attacks and wishing of encryptions such issues can cause a company a abundant sacking as much time leave be pass trying to straighten out the problems which at times are nasty to solve.To protect the workstations in the network from attacks from viruses, Trojan and worms I gave the future(a) suggestions, that the company et up exact security insurance that the rung should tie to so as to manipulate the resources and information in the company are in safe condition, acceptation of assault catching and cake systems in the network to secure the network form any forceful debut into the network.Using methods such as updated antimatter toolkit, the staff can be able to work downstairs a contributory surround which is free from any venomed software attacks, flake affaire is that ascendancy rights and privileges should be given over to certain staff or members in the company, so s to hamper information from being accessed by unauthorized user who get a threat to the company.
