Hello, all.I have found that lots of attackers using /tmp or /dev/shm to save and execute backdoor.
So I would like to secure this directory.. I opened /etc/fstab file and added noexec, nosuid option and remounted. Additionally, how to about ro(read only) option at /dev/shm?file creation is required at /dev/shm? I didn't see any files at this directory. So I think that ro option at this partition is good way against script kid.
Which method or solution is recommendable to secure /tmp or /dev/shm? Thanks in advance. _________________________________________________________________전세계인이 함께하는 웹 메일 서비스인 MSN Hotmail을 만나 보세요. http://loginnet.passport.com/login.srf?id=2&svc=mail&cbid=24325&msppjph=1&lc=1042
