the order of the winning red part, you can understand why. Because the first query returns a column that has more bytes than Max_length_for_sort_data, which causes the sort to be sorted in a regular order, in which case MySQL sorts the rowid and turns random io into sequential io, so it returns 5 in front, 6 in the back While the second query is optimized, there is no process to skim the data for the second time, and the relative position of the sorted record is maintained.

By default, these settings are stored in the default domain policy GPO, but should not be listened to from there. You should analyze local security policies such as DUMPSEC or domain controller (run GPEDIT on the domain controller. MSC. DUMPSEC will not collect the complex requirements of passwords. It collects the information through other channels. The Local Security Policy can provide all the information for listening to these settings.

7. Prevent passwords from being guessed
When our windows 7 user password setting is simpler, it is easy for illegal users to try to "guess" the user password multiple times and log on to the system,
simultaneously audit its success and failure events.
Account Management: Create, modify, or delete users and groups, and make password changes that must audit both its success and failure events.
When you open the above audit, when someone tries to do something to your system (such as trying user passwords, changing account policies, unauthorized file access, etc.), it is logged by the security audit, stored in the security log in Event Viewer.
In addition to the "Local Security policy" can

As you all know, Windows 2003 administrator users cannot be deactivated, which means that others can try this user's password over and over again. Try to disguise it as a regular user, such as GUESYCLUDX.
4. Create a trap user
What is a trap user? That is, create a local user named "Administrator", set it to the minimum, do nothing, and add a super complex password of over 10 bits. This would allow those hacker to be busy for a while to discover their invasion attempts. The follo
