a data analyst is working with a data frame called salary data. they want to create a new column named total wages that adds together data in the standard wages and overtime wages columns. what code chunk lets the analyst create the total wages column?
To construct the total wages column, the data analyst would use the following code: mutate(salary_data, total_wages = overtime_wages + standard_wages).
What is a data frame and mutate function?When storing data in R Studio using R programming language, a data frame is just a two-dimensional tabular or array-like structure which is composed of rows and columns.Creating a brand-new variables from a list of data sets while maintaining old variables is the main usage of a modify function in R programming.The mutate() function from dplyr package in the R programming language allows us to easily add new columns toward a data frame which are calculated from existing columns. The transform() function in pandas is comparable to the mutate() function.Code that can be run in R Studio.
The code fragment in this example that would enable the data analyst to add the total wages column is:

Similar to a burglar alarm, an IDS (Intrusion Detection System) detects a breach of its configuration and sounds an alarm. This alarm can be silent, audible, visible, or both.
An IDPS is tweaked to increase its effectiveness in identifying real positives while reducing false positives and false negatives. A software application or hardware device that can intercept, copy, and interpret network communication is known as a packet sniffer or network protocol analyzer. A packet sniffer can give a network administrator useful data for identifying and fixing network problems.

drew wants to test her company's web application to see if it is handling input validation and data validation properly. which testing method would be most effective for this
The testing method Fuzzing can be used for input validation and data validation for a web application.
The purpose of fuzzing, also known as fuzz testing, is to identify applications with weak input validation. Fuzzing aids in identifying instances where an application makes incorrect assumptions about the data supplied by users by sending incorrect or corrupted data to the application.
Many programmes are built to accept and use data from unreliable users. This could be as straightforward as requesting a name or email address or as complicated as carrying out a transaction on the blockchain.
These programmes frequently assume certain things about the data that is given to them. For instance, it is typical to assume that names have a certain maximum length and are made up of letters (possibly in multiple languages).
It's possible for authorised users of an application to "follow the rules" when entering input, but this isn't always the case for errant users or potential attackers. Bad input could break the application or compromise its security if an application makes assumptions about user-provided data without verifying that the user-provided data satisfies these assumptions.

Explanation:
a network switch is configured to perform the following validation checks on its ports: all arp requests and responses are intercepted. each intercepted request is verified to ensure that it has a valid ip-to-mac address binding. if the packet has a valid binding, the switch forwards the packet to the appropriate destination. if the packet has an invalid binding, the switch drops the arp packet. which security feature was enabled on the switch to accomplish this task?
The security feature that was enabled on the switch to accomplish this task is Dynamic ARP Inspection
Where is dynamic ARP configured?The database of legitimate IP-to-MAC address bindings used by dynamic ARP inspection is called DHCP snooping bindings. The DHCP snooping binding database entries are subordinate to ARP ACLs. ACLs are only used by the switch if they are set up using the ip arp inspection filter vlan global configuration command.
Networks are shielded from man-in-the-middle ARP spoofing attacks by MS switches' Dynamic ARP Inspection (DAI) security function. DAI validates Address Resolution Protocol (ARP) packets by inspecting them on the LAN and using the data in the DHCP snooping table on the switch. 5 Oct 2020
