Defending the Perimeter from Cyber Attacks
PDF Add to WishList
Ensure the confidentiality, integrity, and availability of your organization’s information by protecting your communications and data. In this training course, you learn how to define and implement security principles, install and customize secure firewalls, build Virtual Private Network (VPN) tunnels, and safeguard your organization’s network perimeter against malicious attacks.
You Will Learn How To
- Fortify your network perimeter to provide an integrated defence
- Prevent or mitigate the effects of network attacks with a firewall
- Detect and respond to network attacks with Intrusion Detection and Prevention (IDP)
- Design, instal, and configure secure Virtual Private Networks (VPNs)
- Mitigate the impact of Denial-of-Service (DoS) attacks
