The purpose of including multiple layers in your network security<span> is to make sure that </span>each single defense component has a backup<span> in the case of a flaw or missing coverage. The individual strengths of each layer also cover any gaps that other defenses may lack.</span>
With this assumption in mind, each individual layer in a multi-layered security approach focuses on a specific area where the malware could attack. By working in concert, these layers of security offer a better chance of stopping intruders from breaching company networks than using a single solution.
The types of security layers you can use in your network defense include:
<span>
Web protectionPatch managementEmail security and archivingVulnerability assessment and analyticsAntivirus softwareData encryptionFirewallsDigital certificatesAnti-spam and spam filtersPrivacy controls</span>
<span>Having multiple layers of security in place is crucial for MSPs who protect data at all levels and across numerous applications and devices. Not only should data stay safe, but so should the methods of communication and the network where information is transferred.</span>

Answer:
The number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
Explanation:
This part of the code below
WHERE InvoiceTotal - PaymentTotal - CreditTotal >
(SELECT AVG (InvoiceTotal - PaymentTotal- CreditTotal)
FROM Invoices)
gives the condition to pick the invoices with balance that are greater than the average balance for all invoice.
This part of the code below
GROUP BY VendorName
ORDER BY BalanceDue DESC;
then enables the program to group the result of the above condition by VendorName and sort the resulting rows in the order of BalanceDue. You will therefore, obtain for each row in the NumberOfInvoices column, the number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
