SQL injection usually occurs when you ask a user for input, like their username/userid, but the user gives ("injects") you an SQL statement that you will unknowingly run on your database. For example:
Look at the following example, which creates a SELECT statement by adding a variable (txtUserId) to a select string. The variable is fetched from user input (getRequestString):
txtUserId = getRequestString("UserId");
txtSQL = "SELECT * FROM Users WHERE UserId = " + txtUserId;
If user enter something like this: "100 OR 1=1" then the SzQL statement will look like this:
SELECT * FROM Users WHERE UserId = 100 OR 1=1;
The SQL above is valid and will return ALL rows from the "Users" table, since OR 1=1 is always TRUE. A hacker might get access to all the user names and passwords in this database.

Explanation Private Network Monitoring (PNM) provides visibility and threat detection for the on-premises network, delivered from the cloud as a SaaS solution. It is the perfect solution for organizations who prefer SaaS products and desire better awareness and security in their on-premises environments while reducing capital expenditure and operational overhead. It works by deploying lightweight software in a virtual machine or server that can consume a variety of native sources of telemetry or extract metadata from network packet flow. It encrypts this metadata and sends it to the Stealthwatch Cloud analytics platform for analysis. Stealthwatch Cloud consumes metadata only. The packet payloads are never retained or transferred outside the network. This lab focuses on how to configure a Stealthwatch Cloud Private Network Monitoring (PNM) Sensor, in order to provide visibility and effectively identify active threats, and monitors user and device behavior within onpremises networks. The Stealthwatch Cloud PNM Sensor is an extremely flexible piece of technology, capable of being utilized in a number of different deployment scenarios. It can be deployed as a complete Ubuntu based virtual appliance on different hypervisors (e.g. -VMware, VirtualBox). It can be deployed on hardware running a number of different Linux-based operating systems.
