 For a system administrator, having to perform security vulnerability analysis and software update on a daily basis can be a burden.
 To avoid downtime in production environment, it is common for system administrator to choose not to use the automatic update option provided by package manager and to perform update manually.
 This leads to the following problems.
-- System administrator will have to constantly watch out for any new vulnerabilities in NVD(National Vulnerability Database) and etc.
+- System administrator will have to constantly watch out for any new vulnerabilities in NVD(National Vulnerability Database) or similar databases.
 - It might be impossible for the system administrator to monitor all the software if there are a large number of software installed in server.
 - It is expensive to perform analysis to determine the servers affected by new vulnerabilities. The possibility of overlooking a server or two during analysis is there.

 - Scan vulnerabilities on the servers and create a list of the CVE ID
   - To scan Docker containers, Vuls connect via ssh to the Docker host and then `docker exec` to the containers. So, no need to run sshd daemon on the containers.
