Today with increased
number of LANs and personal computers internet began to creat untold numbers of
security risks. Network security is responsible for securing all information
passes through network computers so it is most vital component in information
security. For network security firewall devices were introduced that enforces
an access control policy between two or more networks. Without network security
many businesses, individuals and governments are at risk of losing their data because
main goals of security are to protect confidentiality, maintain integrity and
assure availability. When we are talking about network security or Cisco security training then three
common terms used are threats, attack and vulnerability.
Weakness can be technology weakness, configuration weakness
and security policy weakness. In technology weakness computer and network
technologies have intrinsic security includes TCP/IP protocol weakness,
operating system weakness and network equipment weakness. In configuration
weakness users have to correctly configure their computing and network devices to
compensate. In Cisco security training
you will learn more about network security and network technologies. So you can
