Operating Systems AIX Why /bin/su permission with SUID? Post 302910427 by Corona688 on Thursday 24th of July 2014 11:36:00 AM

Permit me to be quite extremely blunt. Your auditor is an idiot. He has heard that "SUID is bad" and parroted it, but has no real understanding of it. Following his advice will ruin your machine.

su couldn't possibly work if it weren't SUID. It needs to access the shadow files, which are locked to root!

Now, if there are things which are set SUID but shouldn't be, that would be bad. Having cp set SUID would be a recipe for disaster for example.

ODS-AUDITOR(1)							    OpenDNSSEC							    ODS-AUDITOR(1)

NAME
ods-auditor - auditor component of OpenDNSSEC SYNOPSIS
ods-auditor [options] DESCRIPTION
ods-auditor is a module which provides auditing capabilities to OpenDNSSEC. Once an unsigned zone has been signed, this module is used to check that the signing process has run successfully. It checks that no data has been lost (or non-DNSSEC data added), and that all the DNSSEC records are correct. It used the OpenDNSSEC standard logging (defined in /etc/opendnssec/conf.xml). The Auditor takes the signed and unsigned zones and compares them. It first parses both files, and creates transient files which are then sorted into canonical order. These files are then processed by the Auditor. If processing an NSEC3-signed file, the Auditor will create additional temporary files, which are processed after the main auditing run. Specific options: -c, --conf [PATH_TO_CONF_FILE] Path to OpenDNSSEC configuration file (defaults to /etc/opendnssec/conf.xml) -k, --kasp [PATH_TO_KASP_FILE] Path to KASP policy file (defaults to the path given in the configuration file) -z, --zone [ZONE_NAME] Single zone to audit (defaults to audit all zones) -s,--signed [PATH_TO_SIGNED_FILE] If a single zone is specified, then this option may override the specified signed file with another. This is for use by the signer. (defaults to the path given in the zone list) -v, --version Display version information Common options: -h, -?, --help Show this message ods-auditor 1.0.0rc3 January 2010 ODS-AUDITOR(1)
