Secure Network

In Part - 6 we understood how to secure communication channel. EC Communication is vital part for EC and EC Network is media which transverse EC Communication and so avialability of Network is very important for EC.

Avialability of EC Network can be secured by adequate technology selection based on network design concepts such as -

• Layered security
• Controlling access
• Role-specific security
• Monitoring
• Keep systems patched
• Response team

Below are the Ways and Means to secure Network.

§ Design and Configuration

• Security at LAN & Perimeter level
• VLAN, QoS, Access list, POLP, packet filtering

§ Selection of device

• Firewall
• IDS / IPS
• Proxies

§ VPN Protocols

• Ipsec, L2TP / PPTP, MPLS, SSL VPN
