Summary of Technical Accomplishments

Security/Firewall

Configured ISE to provide AAA services to enterprise network, 802.1X authentication for wired and wireless access to networks. RADIUS server implementation. Access switches, WLAN controllers configured as 802.1X authenticators to relay endpoint credential information on to ISE for processing, including the use of various VLANs based on business needs. Viewing connection logs in ISE. Ticket resolution and change requests; more extensive changes require scheduling during periods of low network utilization, and users will need to be informed in advance if they will experience a change in behavior.

Deployed and Maintained Cisco ASA 5500 series firewalls including Security Levels, Zones, NAT, ACLs, and Active/Standby HA. Also, implemented NGFW features such as URL filtering and other IPS/IDP functions.

Managed an IPSec Site-to-Site VPNs between Cisco ASA5500s at Main Office and Cisco branch ISR specifying IKE Policy, encryption and authentication protocols, access-lists to define VPN traffic, transform sets and crypto-map. Have used both Certificates and Pre-shared Keys.
