Yes Juan has done enough to secure the network

Explanation:

All the computers are patched, have antivirus software, and have unneeded services shut down - this is done to prevent malware from residing in the system.

The network has a firewall with proxy server and IDS - the firewall limit access to network so as to limit intrusion into the network
