Transcript of Network hardening
Cisco security solution
Cisco IOS Software delivers a sophisticated set of security capabilities for a comprehensive, layered security approach throughout your network infrastructure.
Cisco IOS security technologies help to defend critical business processes against attack and disruption, protect privacy, and support policy and regulatory compliance controls.
Cisco IOS Content Filtering
Monitor and block Web activity

protect the network infrastructure against network- and application-layer attacks, viruses, and worms.
Suitable for branch offices, small to medium business environments, or managed services.
It works with other Cisco IOS security features, including Cisco IOS IPS, IOS Content Filtering, and IOS Network Address Translation (NAT), to create a completely integrated branch-office perimeter security solution.

Inline, deep-packet inspection feature that effectively mitigates a wide range of network attacks.
Provides your network with the intelligence to accurately identify, classify, and stop or block malicious traffic in real time.
Faster remediation of the attack
