2. Understanding Network Security
Network security is a specialized field in computer networking that involves
securing a computer network infrastructure. It is handled by network
administrators who implement security policies to protect network and resources
from unauthorized access.
Network security system typically relies on layers of protection and consists of
multiple components including networking monitoring and gateway security
software in addition to hardware and appliances.
Effective network security strategies combine multiple layers of defense at the
edge to protect the usability and integrity of network, data and resources.

Gartner estimates that 2019 will be the tipping point at which gateway security
spending surpasses endpoint security spending.
Half of midsize and large organizations will add bigger, more advanced
inspection-oriented features to their network firewalls by 2019.
By 2020, 50% of SMBs will use mobility or wireless management capabilities
from their UTM platform to enforce distinctive policies, up from 10% today.
