Securing the Network is Critical in Today’s Distributed World
The network is the blood system of the organization, needed to guard networked computer systems and protect electronic data that is either stored in networked computers or transmitted in the networks.
Understanding security means first understanding the nature of evolving threats, including the aspects of your network that could become prime targets, and how such targets could be attacked. Network security functions are designed to provide:
- Availability of useful data (transmitted in public networks or stored in networked computers)
Layered Defense Systems Create a More Powerful Resistance Structure
Improving network security in today’s dynamic threat landscape requires a deep layered defense system that includes multiple layers of defense mechanisms used to resist possible attacks. Attackers are often characterized as black-hat hackers, script kiddies, cyber spies, employees, and cyber terrorists.
Basic network security models are comprised of four components: crypto systems, firewalls, anti-malicious-software (AMS software), and intrusion detection systems (IDS system).
