Recently read a forum post on another forum where it was suggested to go with both cagefs and immunify 360 to protect shared hosting accounts on servers from malware etc. here is the definition of what CageFS does... CageFS is a virtualized file system and a set of tools to contain each user in its own 'cage'. Each customer will have its own fully functional CageFS, with all the system files, tools, etc. CageFS - CloudLinux Documentation https://docs.cloudlinux.com/cagefs.html In reading some of the information i am wondering if either of these two packages are doing anything more than reinventing the wheel that's already available to us. Anyone got any insights i to how they protect their servers? Do you use these kinds of addons? Alternatives? Are they to a certain extent a bit of a con or a waste of money because of what an ispconfig system already has built in? for example, in reading about one of the above software packages, it appears most of what it does is achieved through custom firewall iptables rules? how is Cage File Security through virtualisation, any better than running user jails for example?
