Best tools for red and blue teams are methodology, experience
In many ways, parenting and security have a lot in common. No book exists that provides all of the answers. There is no silver bullet, and both roles can be overwhelmingly stressful.

The greater challenge is for the blue team to protect their domain by finding that one vulnerability that can be exploited without putting too many limitations and restrictions on users.
