Authentication is a very important process for securing web applications. Username and password are two parameters commonly used for user authentication on the administrator's login page. However, such the two authentication parameters can be easily breached so that they can become a vulnerability that adversary parties can use to conduct malicious activities. For example, the attackers can commit a crime such as data modification or theft or even more dangerous take over administrator services of a system. Therefore, it is necessary to improve the security mechanism by adding additional factor of authentication other than username and password. In this study, an improvement in authentication mechanisms was carried out by applying MAC Address-based access control as an additional authentication factor. In this method, Address Resolution Protocol (ARP) is used in mapping the users Internet Protocol (IP) address to their MAC address during validation process. The experimental results showed that the addition of the MAC address made the authentication process resistant to Dictionary Attack and Shoulder Surfing Attack.

Linux is an open source operating system that uses the Linux kernel. The security of Linux makes its users rarely use antivirus to prevent the threat of ransomware attacks. The purpose of this study is to assess the security of the Linux operating system that uses Wine as a compatibility layer against ransomware attacks. Then to determine whether ransomware has a higher impact than malware samples in previous studies or not. The methods used on the 30 samples are static analysis to identify samples, and dynamic analysis to determine the implications. From the 30 ransomware samples that can run on the Linux operating system, the results obtained show that 80% affect the registry, 50% affect the file system, 50% affect the service, 70% affect the Network and 60% affect the Process. While overall there are 30% of samples that affect the five existing parameters. The results show that ransomware has relatively high implications for existing parameters, inversely proportional to previous research.
