file security

If user and group management has you in a quandary, it's time to take the advanced filesystem security class at the ACLU.

IBM Developerworks: "THe NFSv4 (Network File System – Version 4) protocol introduces a new ACL (Access Control List) format that extends other existing ACL formats.

NFSv4 ACL is easy to work with and introduces more detailed file security attributes, making NFSv4 ACLs more secure.

Several operating systems like IBM AIX, Sun Solaris, and Linux have implemented NFSv4 ACL in their filesystems."

Security vendor AVG said Thursday that the company will offer a free year of service, after its antivirus software misidentified a key Windows system file as malware.
