Countermeasure for 0 day Threat?

in SSCP
Hello All!
This is my very first post to this forum, I am sorry if I break any rule.
I have just started preparing for CISSP and planning to crack it in next 6 months.
I am referring chapter #3 (i.e. Information Security and Risk Management) of Shaun Harris AIO CISSP book.
Could you please help me understanding what could be the countermeasure for 0 day threat?
Any help will be appreciated.

Thanks for the reply.
Could you please share any feasible example for the same?
I believe white listing is definitely more rare because it is very restrictive and that could turn into quite a management nightmare.
Hope this answers what you were wanting as an example.

They are also called Behavior or heuristic based IDS/IPS, And the 3 main types of them are - Statistical anomaly based, protocol anomaly based, and traffic anomaly based.
I don't know why they have mentioned this as Only IDS on Books, But I guess we can consider them as IPS also as they prevent and not only detect anything that is against the normal activity.
