Along with the development of current technology, making technology is very important in today's life. Security level digital data has become more vulnerable to exploitation, the problem arises when an information technology device was attacked by people who do not want to take a responsible and important data illegally, so the administrator must act quickly to secure important data. Making a data security technology on the internet is very important information. Limitations administrator underlying the creation of a system that is able to detect and defense systems against such attacks is automation, so that it can be applied to data security. The system is built to prevent attacks on computer networks with more specific on THC - Hydra. This system will analyze the number of errors in the log into the database, and if the error exceeds the tolerance rules are made by the administrator. If the error is more than 3 times in one minute, then with automation, the system will create a rule that can imprison users who do not have such access, and access to the prison in the illegal user can not perform such activities on legal access and access to activities conducted illegal user can be recorded on a file and jail.txt. So under any circumstances and not in supervising administrator, the security of other user data will be safe and can not be retrieved or viewed by a user of illegal access.

Data security is a way to ensure that stored data is safe from corruption and that access to it is accordingly controlled. Data security helps to ensure privacy. It also helps protect personal data from theft. Data theft is one that often occurs on global computer networks. It includes criminal acts in the internet world. Chronology of theft is that an intruder enters a system and retrieves essential information without the owner's knowledge. Intruders use data that has been taken for various crimes. Various ways that intruders take to retrieve the data. This action is proven by the amount of internet traffic that is looking for a gap to infiltrate a system. Cryptography is needed to protect essential data. One of the classic algorithms used is Gronsfeld Cipher. This algorithm works by exchanging characters in messages using substitution tables. The key used is a number that determines the shift of plaintext and key. The resulting ciphertext is the result of plaintext substitution with the key table. This algorithm is constructive for users to secure their essential information when it will be sent through a global network.

 The growing information technology is very rapidly, the more evolving crime techniques to find information that is confidential. The Internet is one of the main media in disseminating information. The use of security on the internet still needs to be developed. Based on these problems, the type of research undertaken in the writing of this final task is the type of experimental research by developing methods that have been done by previous researchers to hide secret data that is inserted into the audio * .wav so that the security and confidentiality of data can be guaranteed. data security can be done with various methods, including cryptography and steganography. Cryptography is a technique for encrypting messages and steganography is a message concealment technique. This insertion type uses binary ASCII character code. In the cryptographic process, using the Vigenere Cipher algorithm and in the steganography, process using the algorithm (LSB) Least Significant Bits. The merger of the two techniques resulted in a better new digital image security system and increased the value of MSE, PSNR and Execution time. Then the test results in the evaluation using BER and histogram analysis. Good audio quality has a minimum value of 30 dB PSNR. In the embedding process using combinations of vigenere and LSB methods, Audio 15 is the best audio compared to other audio. Audio 15 has a smaller MSE (0.001656) value and a larger PSNR (124.138499) value than any other audio when embeded messages *.txt file with character 4096.

<p align="center"><strong><em>Abstract</em></strong></p><p><em>There are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. One of the vulnerable parts of data security is when sending data to the destination. At the time of delivery, tapping of data can occur, so that people who are not entitled to get that information can find out. Therefore, an information needs to be secured so that only people who have access rights can know or get that information. And to maintain the confidentiality of the information, one of the ways is to insert the data into other objects, so that other people do not realize if the object contains important data or information. This hiding method is also known as steganography, and cryptography is added to strengthen the security of the data, that is a science and art to maintain the confidentiality of the message by encoding it in a form that is incomprehensible. The method used in steganography is Least Significant Bit (LSB), the algorithm used in cryptography is the Advanced Encryption Standard (AES), and the software development method used is prototype. The results of this study are all aspects of data security can be achieved, including when passing through the process of sending data through media such as the internet.</em></p><p><strong><em>Keyword: </em></strong><em>Steganography, Criptography, Prototype.</em></p><p align="center"><strong><em>Abstrak</em></strong></p><p><em>Ada beberapa aspek keamanan data yang harus dijaga, seperti: otentikasi, integritas, non repudiation, otoritas, kerahasiaan, privasi, dan kontrol akses.

The internet and NHS Net are used increasingly in UK general practice. A questionnaire survey conducted in southern England examined these applications. 77 (55%) of 141 practices responded. Of these, 71 were connected to one or other service and 27 offered a practice website. Only a small minority used a website for direct patient booking or access to pathology results. Moreover, among those with a practice website, none paid the necessary attention to data security. The survey revealed some fundamental misunderstandings that may partly account for the slow uptake of these technologies in British general practice.
