Re: Canaries
As with everything else there are some companies that provide the alerting infrastructure and send you an email. A quick google search will result in a few companies that provide a managed service.

Re: Hack back
There's a very simple and effective way to strike back, which will not violate any laws, and earn you some gratitude.

As you rightly pointed out, hackers don't use their own hardware, they use compromised machines, usually high-end servers.

The thing to do, as soon as you detect a hack attempt is:

Add a firewall rule blocking the IP address

Look up the owner of the IP in whois

Send your log extract, which shows the hack attempt, to the owner's abuse contact, and CC the country's CERT office

In all cases, the owner will either remove the malware/script or cancel the account generating the traffic. ISP's hate hackers nearly as much as you do, and you'll get cooperation from  every country in the world.

The most satidfying message we received was from a Russian ISP, saying "This user has been terminated..."

We've been doing this for years and, to-date, have seen 102195 sources of hacking removed from the internet.

Do it. It works.

A couple of points
The note about sharing information and working together is well taken. The financial-services sector has been doing this and scaling up their resources here for some years now -- with assistance/collaboration w/ government agencies as well (the latter of which see it as a matter of crime deterrence and national security).

The separate point about "non-prosecutable activity" is similarly well-taken. While I could never advise it as an attorney, risk and compliance professionals need to understand that security is about risk. Sometimes, non-compliance -- while unlawful and unrecommended by the attorneys -- is an effective business tactic.

Re: Open-ports
@Dr.T: Of course, in some cases, accessibility trumps security. The key is looking at which ports are open and which ports are being accessed. Some ports have almost no business being accessed by unknown third parties ever.

Open-ports
If you have an open port on your machine, for example, many people know you have a weakness. Open ports are the same as least privileged approach, closed unless needed.

Canaries
Canaries are less invasive and less passive, and it's less likely even an advanced attacker will realize what happened. I assume it still requires to set it up and monitor, do some resources are needed.

Honeypots
However, they require time to build and monitor, and companies often don't have the resources they need to do that Honeypots are good, it requires resources obviously, you can use that resource to harden you production env.

privileges
Don't give people more privileges than they really need. I think this is important aspect of whole security, and always missed use of least privilege rule.
