Abstract

Although there are many security methods that can be used to block DDoS attacks, for now these methods are arguably less effective, because many hackers have known bugs from the system or security methods. From the background of this problem, testing the security of Linux Mint servers, Linux Mint without VPN and Anti DDoS, implementing network security from hammer attacks on Linux Mint Linux servers with VPN and Anti-DDoS, and testing DDoS and VPN attacks have been successfully implemented. on linux mint. Anti-DDoS and VPN are able to prevent DDoS attacks on Linux servers by blocking unknown IPs from accessing the server and redirecting attacks to virtual IPs provided by the VPN.

Abstract

Bilinear interpolation is a method that is widely used in image scaling where bilinear interpolation can be applied to upscaling and downscaling processes. Several previous researches have shown that bilinear interpolation provides low quality reconstruction results compared to other scaling methods but is still a good alternative considering the lower process complexity compared to other scaling methods. For this reason, a mechanism or model is needed that can be juxtaposed with bilinear interpolation scaling so that the reconstruction results have better quality. Referring to previous research, neural networks can be used in the reconstruction process where artificial neural networks are used to learn features or information that is lost during the downscaling process so that it can be reused during the reconstruction or upscaling process. This research applies inverse backpropagation to help improve the quality of image reconstruction results on bilinear interpolation. The test results show a much better MSE value of up to 40.25% compared to reconstruction using ordinary bilinear interpolation. Meanwhile, the increase in PSNR obtained ranged from 0.4% - 9.7%.

Abstract

As the field of information and communication technology continues to evolve, the potential for digital crimes increases significantly. Information technology plays a key role in facilitating various human activities in the fields of communication and data exchange. The use of digital data, such as documents, photos, videos, and audio, still creates many challenges in proving ownership.. The proliferation of social media platforms like Facebook, Instagram, and TikTok has made it easier for individuals to duplicate, damage, or even steal content, often for malicious purposes related to copyright infringement.To secure digital image data, the technique of fidelity watermarking using Discrete Fourier Transform (DFT) and cryptographic authentication with the Rivest-Shamir-Adleman (RSA) algorithm can be utilized. Watermarking is a technique that embeds information into an image, serving to provide identification marks and secure copyright information. This process does not damage the original image quality. DFT is a watermarking technique that has the capability to convert the image back to the spatial domain after embedding the watermark. On the other hand, RSA is a cryptographic technique that enables data encryption using a public key and decryption with a private key. In the context of image watermarking, RSA is used to secure the watermark information embedded within the image. Watermark information that is encrypted using the public key can only be accessed or decrypted by the party possessing the private key. This enhances the security of the watermark and ensures that the information embedded within the image remains safe, even if the image is shared.

Abstract

The rapid development of technology has changed many aspects of the data communication process, especially in cloud computing. Cloud computing or commonly known as cloud computing is now widely used. With the increase in cloud usage, there is a significant increase in traffic and causes a load imbalance between servers in the cloud environment. To overcome load imbalance on cloud servers, this research proposes the use of load balancing with a round robin method. Load balancing divides traffic equally between servers to prevent overload and system failure. The round robin algorithm ensures fair distribution by sending requests alternately to available servers. Testing shows a significant reduction in error rates when using load balancing. As many as 30 thousand users per second, the error dropped to 42.37%, 50 thousand users per second caused an error of 66.31%, and 100 thousand users per second resulted in an error of 63.08%. This indicates increased system scalability and ability to effectively handle surges in user requests. Overall, implementing load balancing using the round robin method is able to improve system performance in handling high traffic in a cloud environment, maintain stability, and minimize the risk of failure.

Abstract

University of Harapan Medan is one of the private tertiary institutions in North Sumatra which has an informatics engineering study program. The informatics engineering study program is a study program that has many enthusiasts. Every year this study program graduates more than 200 students. To produce graduates who have potential, reliability and competence in the field of technology and information, it is necessary to make a selection at the beginning, namely at the time of admission of new students. There are 5 criteria used in the selection process, including the average report card score, basic ability test, computer ability test, psychological test, and interview. Each criterion has 5 weights of values, namely very high, high, medium, low and very low.  The selection process for admission of new informatics engineering students with a decision support system for the EDAS (Evaluation Based On Distance From Average Solution) method.  Where the stages in this method are by normalizing the decision matrix and looking for the average from alternatives, then from these results calculate the average positive distance (PDA) and negative distance (NDA) as well as the assessment of the weighted attribute weights of SPi and SNi, after that the normalization of positive and negative distance weights is carried out for determining the ranking score. From the results of the analysis carried out using the EDAS method, with a sample of 10 prospective students it was concluded that the 6th order student candidate had the highest score with a score of 0.519 and the lowest score in the 7th order student with a score of 0.14. Therefore, the level of accuracy of the EDAS method in selecting new student admissions is around 20%. Of course, this accuracy value will change with large data samples.
