Label:Access Control List An ACL is a sequential list of permit or DENY statements this apply to addresses or Upper-layer protocols. ACLs provide a powerful-to-control traffic into and out of a network. ACLs can configured for all routed network protocols. IP ACL operationWhen configured, ACLs perform the following tasks:
Limit network traffic to increase
[Lab7] AclAccess control lists are referred to as ACLs, which use packet filtering technology to read third and fourth headers on routerssuch as source address, destination address, source port, destination port, etc., filter packets according to pre-defined rules,So as to achieve the purpose of access control. There are many kinds of ACLs, and different kinds of ACLs

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging the server is not allowed. In this case, an extended ACL is needed to replace the standard ACL application, and in actual application

1.1 Rights Management ACL (Access control List)
ZooKeeper's rights management is the ACL control function, which uses ACLs to control access to the Znode. The implementation of ACLs is very similar to UNIX file access licenses: It uses a license bit to allow or disallow permission control for different operations on a node. However, unlike the standard UNIX li

Oracle instance checks the quota. For activities that are assigned to a user scenario, only those activities that use space in the tablespace are counted in the limit. Activities that do not use space in the allocated tablespace, such as creating views or using temporal tablespace, do not affect quotas. Quotas are added when you use the purge clause to delete objects owned by a user, or when objects owned by users are automatically purged in the Recycle Bin.6. Apply the principle of least privi
