Answer: Limits the row data that are returned.
Explanation: In structured query language (SQL), The where clause is used as a filter. The filter is applied to a column and as such the filter value or criteria determines the values that are spared in the column on which the WHERE clause is applied. All rows in which the column value does not meet the WHERE clause criteria are exempted from the output. This will hence limit the number of rows which our command displays.
For instance,
FROM * SELECT table_name WHERE username = 'fichoh' ;
The command above filters the username column for username with fichoh, then displays only rows of Data with fichoh as the username. All data columns are displayed but rows of data which do not match fichoh are exempted.
Answer:
He should disable UPnP technology to disallow devices to dynamically add themselves to the network without configuration.
Explanation:
- UPnP stands for Universal Plug n Play.
- It is an easiest way that allows gadgets to find all other devices connecting to your network.
- This can also modify router settings to allow devices from outside the network to access the router.
- External IP address can also be obtained by the gadget and a new port forwarding map can be set
- So from all perspectives, UPnP is an open invitation for hackers to scan for the ports and hack into the device.
- UPnP is a vulnerability to the secure system
