Abstract

An important aspect of a computer device is a security system, this security is made to protect the data inside so that it is not easily stolen by other people. Security systems owned by computer devices must be developed so that data remains safe from attacks. Several types of password attacks that are usually aimed at passwords are brute-force attacks, dictionary attacks, and hybrid attacks. In this research, we will focus on brute-force attacks. Brute-force attacks consist of an attacker sending many passwords or passphrases in the hope of guessing. correctly. The attacker systematically checks all possible passwords and passphrases until the right one is found. Or the attacker can try to guess the key which is usually generated from the password using the key derivation function. This is known as a complete key lookup. To make it easier to operate the brute-force attack will use the Kali Linux operating system. In this study we will use passwords that have been obtained and stored in file.txt, the tools that will be used in carrying out the attack are Hydra, Medusa, and Ncrack.

Abstract

In this modern era, the rapid development of science and technology is certainly very beneficial for human life. However, this development can also bring threats, such as cyber attacks. One type of cyber attack that is often used is SQL injection, which targets database security. Three tools that can be used in testing SQL injection are SQL sus, SQL ninja, and The mole. Testing these three tools uses two operating systems, that is Kali Linux and Windows. The test results are measured based on several parameters, namely, the speed of the tool in responding to commands, the number of stages in its application, the features contained therein, and its efficiency. Based on the test results, it is known that only the sus SQL tool successfully injected a website, while the other two tools failed.

Abstract

As we know, in this era of rapid technological progress, we cannot avoid threats to cyber security, cyber security itself is an effort to protect computer systems and data from various threats. In Indonesia alone, as of September 13, 2022, there have been recorded as many as 12.74 million accounts that have experienced leaks, and this makes Indonesia the 3rd country with the most number of data leaks in the world. One solution that can be done to protect the data that is owned is to put it in an archive such as ZIP, ZIP functions to combine several rice into one and reduce the size. And to secure the data in a ZIP file, you can set a password. The password is a combination of letters, numbers and symbols, with this combination it will be difficult for hackers to carry out their actions.

Abstract

This study discusses the methods of encoding and decoding the base64 cryptographic algorithm. The term encoding means a process of converting plaintext into ciphertext. While decoding is a term that means the process of turning ciphertext back into plaintext. In general, classical cryptography has been abandoned because of its logic which can be easily solved, so now it has switched to modern cryptography which operates in bit-binary mode which is formed from ASCII code. The base64 algorithm is a form of modern cryptography which is included in the modern type of block cipher cryptography. This study aims to obtain a comparison between 3 types of tools in carrying out a cryptographic encode and decode process on the base64 algorithm. The 3 types of tools include the Base64 Python Program, Bash Base64 Kali Linux, and CyberChef which are online tools. This type of research method uses qualitative methods because it tends to use analysis in research. Where the results of the first comparison are used to make it easier to see the accuracy of the encoding and decoding processes and the results of the second comparison are used to compare in terms of time efficiency when encoding the three tools using 1,000 words which will continue to be added by 4,000 words, up to a total of 9,000 words . These words are taken using dummy text (lorem ipsum).

Abstract

Along with current technological developments, security for data information residing on websites is very vulnerable to crimes in the internet world such as attacks on security holes in the database layer or often known as SQL Injection. SQL Injection attack is a method to insert SQL commands as input through an application, namely Kali Linux, in order to gain access to the database. This attack can find out usernames, passwords, and other data that is in the database. So that the SQL Injection attack is one of the most popular attacks and is often used to take advantage of security holes in the system because of how easy it is to use it. This study aims to test the level of effectiveness of SQL Injection attacks using the tools in it against a website. Testing the effectiveness is done by doing a comparison between the three tools that are in SQL Injection. The results of the research on the effectiveness of the tools in SQL Injection are the accuracy of database search times and the accuracy of information from the database.

Abstract

Salah satu Universitas Negeri yang terletak di Bali Utara yaitu Universitas Pendidikan Ganesha (Undiksha) menyediakan layanan jaringan tanpa menggunakan kabel untuk civitasnya. SSID jaringan yang terdapat di area kampus Undiksha yaitu ”Undiksha Harmoni” Jaringan komputer ketika sudah di implementasikan tentunya harus dilakukan Evaluasi kualitas layanannya agar kualitasnya tetap terjaga. Mengukur kualitas jaringan dapat menggunakan metode Quality of Servive (QoS). Sejak awal jaringan Wi-Fi di Undiksha yaitu ”Undiksha Harmoni” diimplementasikan, hingga saat ini belum pernah dievaluasi kualitas layanannya sehingga belakangan ini berdasarkan hasil observasi di lapangan dan kuisioner terhadap mahasiswa sering terjadi permasalahan seperti akses yang lambat dan tidak dapat terhubung ke jaringan. Berdasarkan permasalahan tersebut, tentunya perlu melakukan evaluasi kualitas layanan pada jaringan Wi-Fi ”Undiksha Harmoni” dengan menggunakan QoS. Terdapat 4 parameter yang menjadi tolak ukur dalam evaluasi jaringan yang menggunakan QoS yaitu: Throughput, Delay, Jitter dan Packet Loss. Parameter tersebut akan diukur di Area Undiksha pada saat jaringan sedang sibuk dan saat sepi. Hasil pengukuran tersebut akan di hitung sesuai dengan persamaan masing-masing parameter dan kemudian ditarik kesimpulan berdasarkan standar penilaian parameter QoS yaitu TIPHON (Telecommunications and Internet Protocol Harmonization Over Network). Berdasarkan penelitian dengan menggunakan metode action research didapatkan bahwa indeks rata–rata Throughput adalah 3,93, indeks rata-rata Delay adalah 4, indeks rata-rata Packet Loss adalah 3,8 dan indeks rata-rata Jitter adalah 3, lalu dicari nilai rata-rata dari keempat nilai tersebut maka didapatkan rata-rata yaitu 3,68 yang jika diklasifikasikan berdasarkan standar TIPHON kualitas jaringan Wi-Fi Undiksha dengan SSID ”Undiksha Harmoni” Memuaskan.
