Abstract

Indonesia, most cyber incidents reported by respondents relate to loss or leakage of business information such as internal records, information related to customers, employees and intellectuals. This worries the misuse of information held by irresponsible parties. in order to protect information so that it is not misused by unauthorized parties, then an attempt is made to hide the actual information on other information called steganography by using the Least Significant bit (LSB) method and to see the image quality value containing the message using the MSE calculation (Mean Square Error) and PSNR (Peak signal to noise ratio). The process of inserting messages is successfully carried out and produces extraction steganographic images. From testing the picture it can be concluded that the results of the steganography application must be invisible or not visible in plain view, as the purpose of this study is to increase the security sent to arrive at the recipient.

Abstract

Sniffing technique (ARP Spoofing) is an attack that sends fake ARP packets or ARP packets that have been modified according to the network address attacker's to poison the victim's ARP cache table. ARP spoofing attack is a dangerous attack because it can monitor the activities of victims in searching the browser and can steal social logins, office and other accounts. This attack supports the occurrence of other computer network attacks such as Denial of service, Man in the middle attack, host impersonating and others. Sniffing attacks are generally found in places that provide public Wi-Fi such as campus, libraries, cafes, and others. IDS Snort can detect sniffing attacks (Arp Spoofing). String Matching Method KMP algorithm is applied to detect attacks on snort logging files to provide alerts (messages) to users. Tests carried out are black box testing to test application functionality, and accuracy testing. All application functionality was successful, and testing the accuracy of the match between manual calculations for string matching and accurate application.
