- 2. Abstract Network security is main issue of this generation of computing because many types of attacks are increasing day by day. Establishing a network is not a big issue for network administrators but protecting the entire network is a big issue. There are various methods and tools are available today for destroying the existing network. In this paper we mainly emphasize on the network security also we present some major issues that can affect our network.
- 3. What Is Network? A group or system of interconnected A network is two or more computers A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another allowing for data to be shared and used Computers: A group of interconnected (via cable and/or wireless) computers and peripherals that is capable of sharing software and hardware resources between many users. The Internet is a global network of networks. See also local area network and wide area network
- 4. What Is Network Security? Network security is the process by which digital information are protected Goals of security are to protect confidentiality, maintain integrity, and assure availability. To secure the information and the entire network system, one specific methodology is required which can be capable of providing the complete security solutions. The security of network is a big issue for security administrators because network is growing day by day.
- 5. BASIC TYPES OF ATTACKS Here the Author are presenting some basic class of attacks which can be a cause for slow network performance, uncontrolled traffic, viruses etc A. Security Threats: B. Virus Attack: C. Unauthorized application installations: D. Unauthorized Access
- 6. Define Each And Every Type Of Attack A. Security Threats: There are a number of security threats that can be the cause of a network security attack. Main security threats are: viruses spywares unauthorized access to the network resources and data accidental deletion of the files and the uncontrolled internet access.
- 7. Define Each And Every Type Of Attack…… B. Virus Attack: A computer virus is a small program or an executable code that when executed and replicated, perform different unwanted and harmful functions for a computer and a network. Viruses can destroy your hard disks and processors, consume memory at a very large scale and destroy the overall performance of a computer or network
- 8. Define Each And Every Type Of Attack…… c) Unauthorized application installations: Another virus and security attack prevention method is to install only the authorized software applications to our network server and your all client computers. Nobody should be allowed to install any kind of program which can cause security threats such as songs or video programs, codec, gaming software or other web based applications.
- 9. Define Each And Every Type Of Attack…… D. Unauthorized Access: Access to the network resources and data should be allowed only to the authorized persons. Every shared folder and resources in your network should have been accessed only by the authorized persons and should also be scanned and monitored regularly.
- 10. BASIC SECURITY TIPS This basic Network Security useful security tips and methods to secure your network such as… Installing a update antivirus program Email scanning programs Network monitoring tools Internet access policy
- 11. CONCLUSION There are a number of ways, which guarantee for the safety and security of your network. Perform regular network security testing.
