Packets are the lifeblood of the network and most daily computer operations. In virtually every transaction and operation, we leave a network footprint. Only in the case of a local system login accessing applications and data that are locally resident on that system do we not leave a network trace. If we use the Internet, log in via a domain or realm, access a SaaS or other cloud services, or use network-attached storage, we leave a network trace. Because the network is the tie that binds business, leveraging network-focused security analytics is a critical part of security monitoring and response for all connected businesses.
