Feature: #84053 - API to anonymize IP addresses¶
See forge#84053
Description¶
A new API has been introduced which can be used to anonymize IP addresses. This shall help to comply with data protection and privacy laws and requirement.
\TYPO3\CMS\Core\Utility\IpAnonymizationUtility::anonymizeIp(string $ipAddress, int $mask = null)
If $mask
is set to null (default value), the setting $GLOBALS['TYPO3_CONF_VARS']['SYS']['ipAnonymization']
is taken into account.
The following options for $mask
are possible:
0
: The anonymization is disabled.1
: For IPv4 addresses the last byte is masked. E.g.192.168.100.10
is transformed to192.168.100.0
.For IPv6 addresses the Interface ID. E.g.
2002:6dcd:8c74:6501:fb2:61c:ac98:6bea
is transformed to2002:6dcd:8c74:6501::
2
: For IPv4 addresses the last two bytes are masked. E.g.192.168.100.10
is transformed to192.168.0.0
.For IPv6 addresses the Interface ID and SLA ID. E.g.
2002:6dcd:8c74:6501:fb2:61c:ac98:6bea
is transformed to2002:6dcd:8c74::
The default value for $GLOBALS['TYPO3_CONF_VARS']['SYS']['ipAnonymization']
is 1
!
Impact¶
The core uses this API whenever IP addresses are stored, this includes:
Indexed Search uses the new setting for its search statistics.
