RE: Network Engineer vs. Network Security Engineer

Here is the simplified version of whatever my friends discussed.
Think of roles from the perspective of Owners and Custodians. I.e. they are owners or custodian of an information asset.

Owners are your Management (if any, like finance etc) or the Company itself.

Now the person who is operating the network and have access in terms of making the things work is called Network 
Engineer, he / she is the custodian of this asset.

Whereas Network Security Engineer helps the Network Engineer to achieve compliance and standards, w.r.t. policy or 
regulation etc. He / she is not the custodian of the information asset, but is the custodian of the process how things 
are managed. So he / she better not have the explicit administrative access, however for a periodic security review 
both can sit together and find out the gaps in compliance. A penetration test performed by the Network Security 
Engineer, would be an alternative approach for a security review, but it is recommended only if you have achieved a 
certain confidence level. Otherwise there would be leg pulling between the teams.

In your case, make your boss (or the person you report to) transparent about the issues, and identify him about the 
risks involved in the current configurations of the equipment. Document these risk and mail to the Network Engineer and 
CC to his boss and yours too. He should listen to you and take appropriate actions as your guidance.

Hope things are clear now, and a line (having no end points) have been drawn.

Best Regards,
Uzair

Are you using an identity management product of any sort to set rules and
policies and to monitor audit logs? IDM products also assist with
provisioning and de-provisioning of employees.

First.  Any single point of failure.. such as only one person with access to
the systems is poor policy and/or management.  Who audits the actions of the
sole access individual?

After that, job roles and definitions have some guidelines.. but, this sounds
like more of an internal politics fight.  Turf wars are great.

A discussion and review on separation of duties would seem appropriate.

Good luck.

Hi Johnathan,

That is a tough question, and all I could say is that it depends on what you
see your role as, and what the company sees your role as.

Are you the security auditor and developer of security policy? If you are,
then you should NOT have "write" access to the IPS, IDS, Routers, and ASA
devices, because then you would be auditing your own work. In that context,
you should have "read only" access to these devices, and pass change requests
to the Network engineer to make tuning changes. This would enable an adequate
level of segregation of duties.

However, perhaps you are not the auditor, and you are implementing already
established security policy at your company. In that case, you should have
"write" authority to these security devices, as the Network Engineer should
have primary responsibility of network connectivity, and you should have
primary responsibility of security rules.

But some further information might be helpful. What was the reason that the
Network Engineer gave for denying your access? Was it a segregation of duties
argument, or was there something else? Did he deny even read access?

Hello List,

I am Security Engineer/Analyst at a company who is currently building their
security program and have run into a issue on defining a Network Security
Engineer's roles and duties versus a Network Engineer (on the LAN/WAN side)
and where a line is drawn and what should overlap.

This subject came about when I requested access to our Cisco IPS, IDS and
ASAs. The senior engineer (who, by the way, is the only person who has full
access to all of our Cisco routers, switches, IPS, IDS, ASAs, etc.) within my
company fought to disallow my access.

We have Cisco MARS implemented, and I am the primary manager of that device
and require access to our Cisco security devices (IPS, IDS, etc.) to
sufficiently tune and update the appliance.

Was I and am I wrong for requesting access and wanting it? Where should the
line be drawn as far as duties and roles? Not just for Cisco security devices
but on an enterprise wide scale.

I would really appreciate any responses to this.

Than You.

Johnathan
