Solving the cybersecurity skills gap

There is a global cybersecurity skills crisis. The threat continues to grow as there is a shortage of experts to reduce cyber attacks.

One expert believes the field is changing too fast that this issue will not be solved in the classroom. Certifications and other static methods lag behind the latest techniques used by hackers.

The most important skills for a cybersecurity to develop is creativity and curiosity, as well as thinking on one’s feet, skills that are rarely honed while in the classroom. The best learning will be by doing as real attacks are occurring.

INDEX/MATCH or VLOOKUP?

The VLOOKUP function is widely used to retrieve information from a range of data. Although that function works great, most of the time, it does have some limitations.

This article gives a great summary of when to use INDEX/MATCH vs the VLOOKUP function. https://excelzoom.com/3109-2/

Of course, soon in Office 365, this will all go away with the XLOOKUP function

Tools for my fellow academics

As I started my first academic job, it seemed I had more things to organize and keep track of than ever before. Since then I have developed a suite of tools that have helped and allowed me to focus on research.

I hope you find something on this list to help you. I have provided my favorite reusable notebook to citation/PDF manager, as well as editing service.

Match/Index – Best functions ever!

OK — there is a lot of competitions for the best Excel functions. However, Match and Index have to be near the top of any accountant’s list.

There are times that a VLOOKUP, just won’t cut it. Remember, a VLOOKUP requires the lookup value is in the first column of the table array. Sometimes, that just isn’t possible. There are some cases in which you are rearrange the data, but not always. That is where a combination of MATCH and INDEX saves the day!

In the following example, you cannot use a VLOOKUP to lookup the Item Number, using the Vendor Part Number. The Venter Part Number is not in the first column.

The MATCH function searches for a specified item in a range of cells, and then returns the relative position of that item in the range. The INDEX function returns a value, specified by its relative position in a range, from within a range of cells. In other words, MATCH is used to find an item and INDEX is used to return the value of the item.

The MATCH function has the following syntax:

MATCH(lookup_value, lookup_array, [match_type])

The INDEX function has the following syntax:

INDEX(array, row_number, column_number) /html

Using the table above, the following example shows a comparison of the VLOOKUP and the MATCH/INDEX functions.
