what steps you took to lock down your personal phone or computer AFTER installation - include technical countermeasures you purchased and/or installed as well as policies (e.g., permissions) you implemented. Explain why you have or have not taken steps and how easy or hard it is to increase the security of your system by "locking it down". What impacts have you had as a result? Should these policies/countermeasures be default settings? Why or why not?
