I use a similar approach when talking about making something &quot;safe&quot; or &quot;secure&quot;.  Against what?<p>My front door is locked.  That will probably keep out the neighborhood teenagers who might be wandering around looking to grab a laptop off of someone&#x27;s table.  It wouldn&#x27;t keep out a burglar with the minimal skill of &quot;kicking down a door&quot;.  But the obvious adult activity inside of the house serves as a fine deterrent in that case.  A group of 3-4 armed criminals might not be kept out by a few unarmed people, but sturdy steel doors with heavy deadbolts, barred windows, an alarm system, and armed residents could be adequate in that case.  But that wouldn&#x27;t keep out a military attack force; I&#x27;d need my own army for that.  But since there&#x27;s nothing in my home that would be worth sending an army for, that&#x27;s an unnecessary level of security.<p>The point of security measures is to make it more costly for someone to break in than it&#x27;s worth for them, while simultaneously making it less costly for the consumer to gain that level of security than a successful attack would cost.<p>What type of threat does an attacker pose?  What could they gain access to?  What are the potential damages?  What&#x27;s the cost of mitigation?  Your chosen strategy should be based on the answers to those questions.
