Contract to Hire
Cisco Classified Network Services (CNS) was created in the aftermath of 9/11 to deliver rapid-response technical support to the U.S. Federal Government (Army, Navy, Air Force, Marines, DoD, NIS, CIA, FBI). That has expanded to include US State & Local governments, critical infrastructure, and Enterprise customers. CNS now has the capability to support global governments. Part of their mission is being "ready to help all critical services, including financial institutions, healthcare, and others that play a critical role in a peaceful world. "In CNS, we strive to contribute to making the world a better place. Every individual in CNS has their own personal stories that fuel our collective passion in this area."
The role of this network engineer is for a Security Engineer that specializes in ISE. There is one other security engineer that specialize in this area but there are 3 other security engineers, total. ISE is a gatekeeper for a network. It is what determines if you have access to a network. For example, when you go to login, ISE is what takes your credentials upon login, and determines your access. ISE also scans computers to make sure antivirus and malware has been installed and updated. The most common issue is network connectivity-users are unable to connect to the network. The engineer would go into ISE and work with the switches and controllers to determine the issue. He/She has to figure out where in that chain something broken...they may need to configure switches, look at ISE to see policies on servers that are blocking servers, or troubleshoot network connectivity. Issues could be with IEEE 802.1x and/or Wireless LAN Controllers (WLC). Someone with ISE experience should be familiar with those types of issues and troubleshooting. If they have more experience, they may be able to set up posturing. This includes client provisioning, posture policy, and authorization policy
ISE takes care of and supports BYOD. When you bring a new device on, ISE installs everything you need prior to access. This person should be able to set that up and troubleshoot if something is no longer working.
The protocols ISE uses (RADIUS), IEEE 802.1x, and TACACS) have to be configured not within ISE but within the actual protocol settings. This is the same with WLC's. Also helpful to know how to do and interpret packet captures-set up Wireshark on a network and be able to configure 802.1x authentication on the wireless controller.
This person also needs the ability to assess the customer's situation, and help develop an action plan that will result in a resolution. This is not a design/architecture role. This is heavy interaction with their federal customers and troubleshooting the issues.
The day-to-day responsibilities are broken into two parts:
1) 50% of their day (4 hrs) will be spent taking customer calls for support that fall within the network monitoring space. This will be operational and reactive. As cases come in, this person will work them to resolution according to priority level.
2) 50% of their day (4 hrs) will be spent working backlogs (cases that have accumulated and need to be resolved).
The engineers day typically consists 2-3 new issues per day and 10-15 cases in their backlog. This is a stark contrast to the TAC, where they typically have 50 cases in their backlog.
All of these will require some combination of the following: troubleshooting, scheduling meetings with vendors and/or customers, recreating the incident and working the case in a the lab, or working collaboratively with other engineers.
This role is not like a help desk. This person will be doing higher level troubleshooting that requires the SME to be very technical, working with multi-vendor, integrated solutions.
