Summary
In this chapter, we covered a lot of ways to enumerate a targeted network. Some of these methods are caused just by the way networks and the internet are designed to work. From protocols such as LDAP and NTP to services such as NetBIOS and DNS, there's a lot to watch out for. Again, remember what I taught you earlier: you can't stop attackers – you can only slow them down. Don't get discouraged by not being able to stop some of these issues. Instead, be aware of them and monitor them closely.
In the next chapter, we'll look at how attackers find vulnerabilities on our infrastructure and how we can be one step ahead of them by using the same techniques to keep our systems up and secure.
