According to the Burning Glass report titled Job Market Intelligence: Cybersecurity Jobs, 2015, 5% of all cybersecurity job postings are for a job title of Security Architect. Unfortunately, the industry is still unclear as to exactly what an IT Security Architect is. According to Payscale, the median compensation is $114,000/year, (which sounds a bit low). The concept is, however, starting to mature. Certifications are being developed for IT Security Architects, and training courses are offered by various organizations to help prepare one to be a Security Architect. The (ISC)2 organization has created an ISSAP (Information Systems Security Architecture Professional) certification. The SABSA organization offers a set of integrated frameworks, models, methods, and processes, used independently or as an integrated enterprise solution. Monster.com listed a job description for a Senior Security Architect, that lists the following skills:"Network Security, Network Hardware Configuration, Network Protocols, Networking Standards, Supervision, Conceptual Skills, Decision Making, Informing Others, Functional and Technical Skills, Dependability, Information Security Policies".
The TOGAF, (open architecture), certification has to do with thinking like an architect. A security architect needs to be able to function as a general systems architect for the enterprise. Without the big picture, it’s hard to provide big security solutions.
A security architect should have the ability to conduct "as is" process gap analysis, (where are we now, where do we need to be, how to get there). They generate technical implementation and management prioritized guidance that includes evaluation tests and metrics such as those identified in the CCS/CIS Critical Security Controls. The implementation is a cooperative effort between business management and the Security Architect who brings needed experience, expertise, and consultation to the decision-making process.
Engineer and Architect compared
Architects know what needs to be done to get you to end goal, engineers know how to do details of next tactical step in the project.
Architects tend to think in concepts; defense-in-depth, least privilege, breaking the exploit kill chain. Engineers tend to think in products; Firewalls, IPS, Anti-malware, file integrity monitoring, DLP, etc.
Architects worry about how the ecosystem works together, engineers worry about how to keep things running and working.
An engineer can tell you how to design your network. An architect can tell you why it should be designed that way, and will be able to suggest changes based on your specific needs.
An engineer can tell you which protocols companies should use for discrete tasks. An architect can explain why those protocols make the most sense, and can usually detail the previous state of the art.
Architects want to know exploit vectors and what intellectual property was exfiltrated from the company, engineers want to collect evidence and remediate.
Architects think vulnerability management, engineers think patching, hardening and scanning.
Architects think big picture and are good presenters and salesmen of security ideas to upper management, engineers are where the rubber meets the road, (the real problem solvers in the trenches).
You have to have both, most security professionals function better on one side or the other, nothing is worse than having an architect that only wants to engineer or an engineer who only wants to architect. However, many companies struggle because they ask a single person to do both and then are frustrated that that person has a weak spot on one side or the other.
The key attributes of an architect in order of importance:
- Analyze the business operations of the organization and map them to data flows between the information processing zones within, as well as to and from, the organization.
- Design a security solution which suits the risk appetite and the real threats the enterprise faces. They use the basic classes of cybersecurity tools available, such as perimeter protection, detection, OS protection, identity management and SIEM style information correlation to implement defense in depth at choke, or control points, of the enterprise.
- Understand the "big picture" in terms of all IT systems, if you don't securing them is impossible. In critical infrastructure organizations, understanding the physical security controls is crucial and architects may be "dual hatted", cybersecurity/physical security.
Ideal persons to help interview a candidate for an architect position include: the IT manager, (such as CIO), security manager, (or CISO), network manager, (or senior network analyst), systems manager, (or senior systems administrator), applications manager, (or senior software developer with a cybersecurity interest).
Interviewing an engineer for a network architecture position
We interviewed a number of GIAC Advisory Board members who have been working as architects for major enterprises as to what they look for an architecture position. They recommend that you be careful about giving candidates a real world problem (even pretending it is 'made up') as this could be dangerous to a company either from a PR or security perspective if it got posted on the Internet in some way. There are a number of practical assignments defining a mythical company called "GIAC Enterprises". If you Google that term you can get some scenarios to use for the exercise. Here are some questions they recommend asking:
Do you have a home network setup? Please describe it to me.
When designing an architect/infrastructure for security we have to be at least "aware" of the various protocols/technologies used within Corporate America. Please tell me a bit about:
- Equal cost paths for egress traffic
- High Availability Design issues
- Packet shaping
- The role of the network in compliance
- What ideas do you have to improve our DR/BCP
- Proxy ARP
- Static routing
Give them just the hex of an IPv4 packet or a DHCPv6 trace and ask them to tell you what is going on. They don't have to be packet ninjas, but they should know what is going on. We teach managers to do this with prospective employees, (in the course we author and teach, Management 512).
Interviewing an engineer for a security architecture position
- What threats do you perceive in this company's environment?
- What are the assets and/or business processes (5 maximum) you think are the most critical ones for the organization?
- What assets do you think are the most exposed?
- Identify the weakest links in the system as a whole (Networks, Systems, Applications, Data, Users).What basic access controls would you design into the network (relevant to my business)
- What if any IH procedures would you put into place regarding the network.
- If you were an attacker, what would you be after?
- If you were an attacker what would your business model be? That is, how can an attacker make money by attacking us.
- If you were an attacker, how would you go about penetrating us?
- What architectural solutions (Protection, Detection and Reaction) would you propose for the different components (Networks, Systems, Applications, Data, Users) to address the threats and mitigate the risks?
- Draw for me a high level (network) diagram that shows your proposed architectural changes and solutions.
- Develop an implementation plan for those solutions (short/middle/long) term.
- Out of the solutions you mentioned, what are the 5 ones that add the greatest value?
- Show me how would you adapt your solutions and what would you prioritize according to different budgets: $1.000, $10.000 or $100.000
- What are the solutions that you think would be more difficult to implement (due to technical, budget or cultural reasons)?
- What policy / cultural changes do you think are needed (if any) for your long-term plan to succeed?
- Propose a couple of security solutions that would enable this company to improve business by doing something it can't currently do.
- If we are looking more of general purpose architect, consider some of these questions. If our organization wants to field a new ecommerce sites, can you describe a couple different scenarios or approaches to the architecture. What are the primary tradeoffs between architectures? What vendors would you use and why?
- Get your technical folks to help you identify a real world problem your organization is facing. Can the candidate engineer a "duct-tape" solution to temporarily address the issue. You don't want a candidate that is always relying on spending $$$ to accomplish a task.
- Please explain a recently announced vulnerability of your choice, and what solutions you would implement to mitigate the threat.
- Here is a whiteboard and some markers... draw me a diagram, design, or something of your choice using these tools to communicate a concept, architecture, or something of your choice.
- Tell me about your experience with the open-source movement. What sources do you use to find information on new products related to network monitoring?
- If there was a network problem, what are the basic steps you would go through to in order to troubleshoot the problem?
- What architectures, software, or deployment strategies have you used successfully in the past, but would no longer use? Please tell us why.
- Sell us on yourself. What are your strongest personal assets? What specific attributes would you be bringing into the organization that will make a positive contribution to our overall success?
- Tell us about an instance when you had to communicate an idea/process/procedure to a customer that you know will be resistant to you. What was your initial approach? Did you have to change your approach? What was the outcome?
- What approach do you take when you need to learn about a technology? Do you consider yourself a life-long learner? Why?
- What was the one question we did not ask that you came prepared to answer?
