My question is not about sudo itself, it's about the possible risks (if any) of having a default installation (FreeBSD7-RELEASE) which assigns ownership of the root folder to root:wheel, thus allowing anyone with wheel privileges be able to see (and copy btw) root folder contents. _ With Windows Live for mobile, your contacts travel with you. http://www.windowslive.com/mobile/overview.html?ocid=TXT_TAGLM_WL_Refresh_mobile_052008___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I don't have any issue in terms of functionality. But the doubt I have is if having the root folder created with ownership root:wheel can become a security issue or not. Also would like to know if there is no problem changing my root folder ownership to root:root (which will require a root group btw). Please do not top post. There is no reason for a root group. I think best practice is to have each admin keep their data in their accounts which are either allocated as name:wheel or they are defined as being in the wheel group. I do not know if sudo requires wheel membership. I do not understand the need for a root group. I think security liabilities from having a wheel group have long been worked out. What do you see as a problem? Is BSD different from linux in this regard? perhaps the latter question is an off-list topic. _ Douglas Denault http://www.safeport.com [EMAIL PROTECTED] Voice: 301-469-8766 Fax: 301-469-0601 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Btw, that's just my opinion. Not sure why it would be a security risk. wheel is the group for people who are allowed to su to root, so you should probably expect members of group wheel to have (or be able to get) root privs anyway. I'm not sure whether by ``root folder'' you mean / or /root , but in either case the wheel group doesn't have write access, at least on my system,and root's umask is 022, so created files aren't writable by members of wheel either. Lazy admins, of course, are a security risk. No-one should ever be given more privileges than they need, and as others have pointed out, sudo is a good answer to this problem. (In fact the first four ports that go on every box I set up, before I even think about what the box is for, are www/lynx, sysutils/screen, ports-mgmt/portupgrade and security/sudo ).
