Container systems are type of virtualization technology with isolated environment. The isolated environment in container system does not make cyber attacks impossible to occur. In this research, containers in which a cyber incident occurred were forensically tested on the container's memory to obtain digital evidence. The forensic process is carried out using standards from NIST framework with the stages of collection, examination, analysis and reporting. The forensic process begins by performing a checkpoint on the container to obtain information from the container's memory. In Podman the checkpoint process is carried out on one of the containers and will produce a file in .tar.gz form, where this file contains the information contained in the container. After the checkpoint process is complete, forensics is then carried out by reading the checkpoint file using a tool called checkpointctl. Forensic results showed that the container was running a malicious program in the form of a backdoor with a PHP extension.

The development of information technology has penetrated various areas. This is driven by improved service, rapid increase in information needs and decision making. General elections that are held every time always leave problems about securities and speed of recapitulation. This is because the process is done in the traditional way. This research tries to apply blockchain technology to the e-Voting system security engineering process so that it creates a votes recapitulation process that is fast, accurate and accompanied by transparency values to maintain the reliability of the existing vote and maintain the confidentiality of the vote data being transacted. Transparency and confidentiality of voter data is a fundamental value in general elections or voting that must exist. Seeing this, blockchain technology deserves to be applied because the principles that needed can be met by applying this technology to the e-Voting system.
