What can go wrong if every user of a Linux system has unlimited access to resources?
What will be an ideal response?
If every user of a Linux system has unlimited access to resources, like core files and memory, then malicious users can conduct denial-of-service attacks on that Linux system by engaging all of the resources available. To avoid these types of attacks,you need to apply resource limits to all users. To do this, you use the /etc/security/limits.conf file. This file permits you to prevent users from creating core files, to restrict the number of processes they can use, and to restrict the use of memory.
