grammar - Correct construction for "easily protected against"

What I am trying to express is that I have a problem P and a good G and it is easy to protect G from P.
However, G is not the focus of the sentence and P was described in the previous sentence.

So I would like to say something like:

There is the additional problem P. However, it is easily protected against.

With it referring to the problem P and without going into what G is again. However, the construction seems complicated and possibly plain incorrect. What we would be a good expression?

I also considered:

There is the additional problem P. However, it is easy to protect against.
