Network Security Measures
Firewalls are hardware, software or a router that monitors the incoming and outgoing data packets of a network and rejects any unauthorised data packets.
Think of it like an airport security checkpoint in your network. It monitors all the data packets to ensure what is coming in and out is authorised to enter/leave the network.
Firewalls can be adjusted depending on the user's security appetite. Strict firewalls can reinforce tight security, however, can also block a lot of legitimate data packets into the network.
Passwords are a combination of characters, often associated with a username, used to unlock certain computer resources.
Google's Tips for Strong Passwords

A secure way to store heaps of complex passwords is to use a password manager. A password manager uses secure, encrypted databases to store all of user's passwords, which can be unlocked using one secure key.
Examples of password managers include:

Restricted access to server rooms - this can be done through keycards or biometric security
Locking doors after use
Fences and barbed wire around data warehouses
Reducing/removing windows and installing thick walls to reduce the risk of outside penetration into the data warehouse
