ACLs are a kernel (core build of the OS) extension and the way ACLs are implemented are dependent on the UNIX variety. Some UNIXes support ACLs, other do not. Please specify the kernel details of the UNIX you are running.
Quite a few years ago I was hanging with Linus and crew at the 1st Linux conference in Amsterdam. I pleaded with Linus to add ACLs and ACL event logging to the Linux kernel so my more security minded clients could run Linux. I am not sure if Linus ever added ACLs to the Linux kernel. He was dead-set against it many years ago (this was around 1994 so things might have changed).
I know HPUX has a very nice ACL system in the kernel. In fact, the HPUX ACLs are so good that many high-availability systems run HPUX for that reason. ACLs in HPUX can be set for things like kernel system calls, etc. The entire system can be set up to monitor and log system calls that the administrator deems necessary for security.
Systems that do not implement ACLs with a high degree of granularity are not normally used in high-assurance systems. (Let's don't get into defining 'high-assurance' in this thread, OK
)

5. HP-UX
Hello,
I try to find what year HP-UX got support for ACL (Access Control List)? I know that HP-UX was the first Unix with ACL support, but it is very hard to find the information on when that occured.
So anyone here know when that did happen?
Any answers are appreciated,

FTPUSERS(5) Linux Programmer's Manual FTPUSERS(5) NAME
ftpusers - list of users that may not log in via the FTP daemon DESCRIPTION
The text file ftpusers contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon. This file is used not merely for system administration purposes but for improving security within a TCP/IP networked environment. It will typically contain a list of the users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP server daemon. Such users usually include root, daemon, bin, uucp, and news. If your FTP server daemon doesn't use ftpusers then it is suggested that you read its documentation to find out how to block access for certain users. Washington University FTP server Daemon (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers. Format The format of ftpusers is very simple. There is one account name (or username) per line. Lines starting with a # are ignored. FILES
/etc/ftpusers SEE ALSO
passwd(5), proftpd(8), wuftpd(8) COLOPHON
