Abstract

Data and information security makes information technology must be updated at all times. Along with the ever-changing information technology development, making information security is very important. Many attacks carried out by irresponsible people to attack the server. These attacks are often performed on open ports, which in turn will allow unauthorized and unauthorized people to easily control ports that have been entered. So to do security on computer network in overcoming attack on ports, one of them is by using Port knoking method. In order to avoid attacks carried out in the open port state a Port knoking method is used and set parameters for this computer device to have no open communication ports to enter, but the device is still accessible from the outside. So as to make people who do not have access rights do not have the opportunity to enter the ports that exist.

Abstract

The access point configuration used for wireless connections in Amikom is manually configured one by one. Each access point is configured using several SSIDs based on the department that will connect to the access point. The use of multiple SSIDs in one access point turned out to have a bad effect on network performance, from the test results, for access points configured with more than four SSIDs, the connection was very slow. The security standard used for connection from the user to the access point is WPA Personal, where WPA Personal can be said to be very weak because for each SSID it will use the same user and password for all users, this is often the cause of access leaks. To improve network security and make it easier for the author to do maintenance on the network, the author tries to use the IEEE 802.1X protocol that is connected with RADIUS and access point controllers so that the configuration and maintenance of wireless networks can be centralized, user administration and passwords can also be centralized server radius and also a better level of security using WPA Enterprise security in the IEEE 802.1X protocol.
