Containerization technology becomes one of alternatives in virtualization. Docker requires docker daemon to build, distribute and run the container and this makes the docker vulnerable to an attack surface called Docker daemon Attack Surface - an attack against docker daemon taking over the access (root). Using rootless mode is one way to prevent the attack. Therefore, this research demonstrates the attack prevention by making and running the docker container in the rootless mode. The success of the attack can be proven when the user is able to access the file /etc/shadow that is supposed to be only accessible for the rooted users. Findings of this research demonstrated that the file is inaccessible when the docker is run using the rootless mode. CPU usage is measured when the attack is being simulated using the docker run through root privileges and rootless mode, to identify whether the use of rootless mode in the docker adds the load of CPU usage and to what extent its increased. Results showed that the CPU use was 39% when using the docker with the rootless mode. Meanwhile, using the docker with the right of the root access was only 0%. The increase of 39% is commensurate with the benefit that can prevent the docker daemon attack surface.

We require a very good technical knowledge to create automated tests to exploit the browser vulnerabilities. It is usually a combination of technical abilities and set of specific tools. Security concerns is of prime importance when it comes to web browsers. Attacks during surfing, executing any downloaded file and while transmission are very frequent these days and hence all browsers need to be hardened to ensure security. Sandbox is one of the feature where we can prevent malicious applications to run directly on hardware. It is an environment where new or non-trusted applications are executed. Many leading web browsers are trying their level best to implement sandbox. In this paper, we have mentioned the basic necessity of sandbox, current implementations in different web browsers and also present a self-proposed approach.
