This is particularly convenient for enterprise engaged in networking and administration & training activities. MAIN SERVICESinstallation and adminstration in the university MAIN USERS FROM CISCO ACADEMYteachers, students, campus workers and also around university community gain main services and knowledge.

KIOT DATA CENTER

KIOT NETWORK DIAGRAM AND SYSTEMS:VLANs can be used to partition a local network into several distinctive segments,

KIOT SERVERSan application (software) capable of accepting requests from the client and giving responses accordingly.

serverWeb servercomputers that deliver (serves up) Web pages

used to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, or other web uses.File serverattached to a network that has the primary purpose of providing a location for shared disk accessFTP(File transfer protocol) used to transfer computer file from one host to another,such asd by internet.

Application server a program that handles all application operations between users and an organization's backend business applications or databases. high performans and high avelablity

Proxy serverthat acts as an intermediary for requests from clients seeking resources from other serversUsed to Monitoring and filtering

Challenges and problems faced during worksoftware were not given prior to the internshiptheoretical knowledge and practical achievements cannot be inter-connect each other for uslanguages are difficult to understand. Lack of skilled laborerMeasures to Overcome Challenges We tried to refer some materials like books & handouts, ask my supervisor and other concerned individuals about courses that were not given by the department.We decide to learn some software Lack of skilled labor was overcoming by sharing our knowledge and simultaneously we have got practical experience from them.

PROJECT WORKWIRELESS MAXIMAIZATION AND SECURITYPotential Network Connectivity Problems in KIOT: LAN terminators are not connected properly.The LAN interface has the wrong IP address.The same IP address is used by another system.The routing table is configured incorrectly.The LAN cable is defective.The LAN segment is too long.The /etc/hosts file is configured incorrectly.Not secure the AP.Less Wi-Fi coverage.

OBJECTIVES:Secure the APDefine Access Point, WEPAble to configure APMaximize Wi-Fi coverage in KIOTAble to connect Infrastructure Mode And Ad-Hoc ModeService set identifier (SSID) A simple code that identifies the WLAN. Clients must be configured with the correct SSID to access their WLAN. Media access control (MAC) MAC address filtering restricts WLAN access to computers that are on a list you create for each access point on your WLAN. Wired equivalent privacy (WEP) Encryption and authentication scheme that protects WLAN data streams between clients and access points (AP) this was discovered to have flaw.

benefits of implementing WEP:All messages are encrypted using a checksum to provide some degree of tamper resistance.Privacy is maintained via the encryption. If you do not have the key, you cant decrypt the message.WEP is extremely easy to implement. Set the encryption key on the AP, repeat the process on each client, and voila! Youre done!WEP provides a very basic level of security for WLAN applications.WEP keys are user definable and unlimited. You do not have to use pre-defined keys, and you can and should change them often. Encryption weakness improved but not solved Increase Wi-Fi PerformanceReposition your routerUse only one wireless standardUse WPA2 securityChange your wireless channel: Its best to check channel usage with a program likeVistumblerorin SSIDer,Upgrade your wireless adapters

network conectivity set up Maximaize RF coverage Ifaccess points are too far apart, then some users will be associating with the wirless LAN atsomething less than the maximum data rate. For example, users close to an 802.11b access point may be operating at 11Mbps.

Wired connectin

upgrade router setupSome hints to protect a WLAN from attack: Ensure compatibilty to use hardware from one vendor, use wi-fi certified devices. Change default ssid and disable ssid broadcasting. Use mac-adress authentication if you have manageable number of clients and only some aps. Not only for enterprises: implement user authen. Upgrade AP to use WPA or WPA2/802.11i. Enable and use wpa2, wpa or for older hardware that supports wep, enable this. Uses it at least with 128bit-wep. Change wep-key frequently

CONCLUSIONwireless networks are preferred by most people, because there is also a greater usage of mobile devices, such as laptops, mobile phones, tablets. It has strengthened my technical based and enabled me to integrate theory with engineering practiceWe developed good confidence that will make me familiar to the work place or position in my futurityWe have understood both office and site works in a satisfied way.In general the internship was important in getting many experiences, knowledge and skills from concerned professionals.RECOMMENDATIONSThe wireless AP is not secure and not setting in proper position or place.Wrong cable installationThey should organize their material management before used as networking purposeThey should work for minimum waste during cutting and installingThey should be volunteer to answer questions when some questions raised from the interns.We would like to recommend that the Electrical engineering department add software course (network security, network administration, and Cisco packet tracer etc.) to their undergraduate curriculum.
