We are living in the world of Information Technology, where Networking is used everywhere such as organizations, homes, shops, education, games, news etc. Through networking not only we can share ideas, information, images, audio, video games etc, but also can use the other services like shopping, business, education, ticket booking etc.

Networking is the backbone of Information Technology. Every company needs professionals from these areas. We have all relevant training courses for you to get the valuable knowledge, experience and make your career in the field of networking. After completing course successfully, you can opt career as Network Analyst, Network Administrator, Technical Consultant, and System Administrator in reputed companies.

Now a days, two most important networking that are usually used 1) Windows networking and 2) Linux based networking. In windows networking we provide knowledge and training of install, configure, and implement the networking and how to successfully maintain that environment through various hardware and software in windows environment. While, Linux based networking consists networking of different Linux based system. Here, we provide training of planning, installing, configuring, implementing and maintaining networking in Linux environment.

Networking is basically connecting two or more computers or communication devices so that they can share the information. Network can be classified according to the geographical area. Local Area Network (LAN) is small network generally used across single home or organization, while Wide Area Network (WAN) covers bigger area such as city, state, counties. Networking can be possible physically as well as virtually. Physical networking needs cable for communication, while virtual networking works without cable, it is also called wireless network.

Usually, there are two types of network design

(1) Client Server System: Where a centralize computer as works as sever, provide various services to its client computers. Client computers request for services or resources to Server and get the resource when server provides.

(2) Peer to Peer Network: There is no client server relationship in that, every computer machine has equal responsibility; it is basically used for sharing information among different machine.

Network topology describes the structure of network for data flow. Most of the topologies that are currently used bus, star, mesh, network, ring etc.

There are certain set of rules or format that allow communication within network that is called protocols. Currently, most popular protocols used in the network are TCP/IP, ATM, and OSI etc.TCP/IP protocol used in internet for communication. These protocols are divided into number of layers and each layer has its own tasks and responsibilities for communication. There are number of devices that are used to connect different networks or computers for maintaining communication. These devices are router, bridge, hub, gateway etc that work on different layers.

Repeater: It is a communication device that connects two or more systems on network. It generates signal but not amplify.

Hub: It is like multiport repeater and generally used to divide a single LAN to multiple levels.

Bridge: It connects similar/dissimilar LAN.

Router: A device connects networks using different protocols and architectures and select routes for network traffic.

Gateway: This device is used as interface between two networks by maintaining protocol compatibility.

Now days, in cut throat completion, every company is concerned about the security of data/information of its own and its customers from the competitors or any user that can misuse any confidential information that is why they are spending lots of money and resources for security purpose .That is why there is huge requirement  of professionals  from this field. It is expected that in near future, demand of the network security professionals will increase up to 50% more then the current.

CEH, CISSP, CHFI etc are those certifications that are especially designed for network security. The aim of the Certified Ethical Hacker (CEH) is to facilitate the organization to take preemptive measures against malicious attacks by attacking the system himself; all the while staying within legal limits. CISSP (Certified Information System Security Professional) is certification that specifically focused on security standard, security policies & procedure. CHFI (Computer Hacking Forensic Investigation) is certification that provides training about the monitoring, detecting and report to any legal evidences. These professionals can extract information from computers such as recover data from damaged or deleted file. Here, we offer you relevant training courses that will enhance your knowledge, experience and make your career in the field of network security. After completing course, you can opt your career as a Security Consultant, Security Administrator etc on reputed companies.

Protection of data/information from unauthorized use and user within and outside the network is called Network security. There are three important pillars of information security.

1) Confidentiality: Data/information should be accessible only to the authorized user not others.

2) Integrity: The information or data that is available should not be change, only authorized person can make changes if necessary.

3) Availability: Meaningful information should be available to the authorized user within time.

For network security, a network administrator plays an important role. He decides security policies and procedure, rights, access, and use for any user on network. He is responsible person for monitoring all the activities in the network and can take necessary measures as per requirements.

Internet (networks of network) is the network that usually used by most of the organizations in correct scenario and their personal network (Intranet) connect with it. Most of the threats, virus, and spams can enter in personal network from this. That is why internet security is mandatory now a day.

There are number of techniques used for network security especially to protect from internet such as

1) Login system: This basic technique, use to protect data form other users. In this, data is protected by user name and password.

2) Firewall: It can be hardware or software or combination of both that is use to protect data within network from the outside network such as internet.

3) Access control: It is the protection usually given by administrator, allow access to any specific user for particular resource.

4) Antivirus: This is a software that protect system by monitoring virus attack and take the necessary measures to protect the system.

5) Cryptography: This technology specifies data conversion to some other means and can be accessible only by authorized person which has key to unlock.

6) Backup: It specifies copy of the files or system for protection of any damage or crash within system in future.
