The role of InfoSec professionals has morphed into a critical business function. One should expect getting involved in “business” discussion often, and at increasing higher levels of business structure up to board of directors. Understanding and speaking business language is more important than ever for the success of any InfoSec professionals. Knowing basic business lingo is also crucial for effective communication inside an organization.
Lack of basic business knowledge and common business terminology hinders success and progress.
I have started creating a body of knowledge for basic business skills required for success of security professionals and elevating their status in the business hierarchy. Following are eight major domains of essential business knowledge for information security professionals.
DOMAIN 1 – Essential Business Terminology for InfoSec Professionals
DOMAIN 2 – Business Communication for InfoSec Professionals
DOMAIN 3 – Funding Requests and Managing InfoSec Budget
DOMAIN 4 – Working with Vendors and Partners
DOMAIN 5 – Building Alliances, Collaboration to Advance InfoSec Goals
DOMAIN 6 – Excellence in InfoSec Customer Service, Knowing and Serving Customers
DOMAIN 7 – Creating Business Value with InfoSec
DOMAIN 8 – General Soft Skills to Succeed as InfoSec Professional
While the diagram shown here is a draft version, a much more detailed body of knowledge and a program to acquire this knowledge/skills will follow.
What are Major Skill Gaps?
ISACA published a report on “State of Cybersecurity 2022” in which they presented their findings on the global workforce. The most striking of all the findings is Figure 14 of the report showing major skill gaps among security professionals.
At the top of these skill gaps is “soft skills” that includes communications, flexibility, leadership and others. This is similar to what we have been talking about creating a body of knowledge for Core Cybersecurity Skills and Practices. Please see a screenshot of Figure 14 from the ISACA report (the report is available for download at https://www.isaca.org/go/state-of-cybersecurity-2022).

I have included six specific recommendations with the recent publication of CISO MindMap. This article is to further elaborate on these recommendations, why these matter, and what actions information security leaders can take. The objective of this article is to provide context for these recommendations and a starting point to take some actions. The actual strategy will vary for each organization depending upon how their IT environment and networks are designed and implemented.
Recommendation 1
Re-evaluate ransomware defenses, detection and response capabilities, perform a business impact analysis and identify critical processes, applications and data.
Why it matters:
Ransomware is widespread and will continue to be in the near future, as it provides a quick monetization path to attackers. In many industry sectors, it also touches human life and safety (energy, healthcare, manufacturing, shipping, etc.) making it even more impactful.
Ransomware attacks have high visibility among corporate boards and executive leadership.
What to do:
Perform business impact analysis with an objective of identifying critical assets, processes, applications and data.
Evaluate security controls to protect these assets. Buy insurance.
Test online and offline backups to ensure backups can be reliably restored within recovery windows.
Evaluate your capabilities of dealing with ransomware attacks by mock drills and tabletop exercises.
Recommendation 2
Reduce/consolidate security tools/technologies and vendors. More tools don’t necessarily reduce risk but do add the need for maintaining expertise on security teams.
Why it matters:
A Ponemon study shows that the InfoSec teams have an average of 47 tools. Also, 53% of leaders are not sure if these tools are working.
More tools need more staff, more cost, more probability of becoming shelfware.
Fewer tools that are properly configured and fully utilized, actually work better in managing and optimizing risk.
What to do:
Take an inventory of all security tools and their features.
Identify feature overlap and eliminate redundancy.
Eliminate shelfware (tools that are purchased but never used).
Explore use of Cloud based subscription services. These are relatively easy to maintain over time.
Simplify!
Recommendation 3
To serve your business better, train staff on business acumen, value creation, influencing and human experience.
Why it matters:
Studies from organizations like ISACA show that “soft skills” is the largest gap among infosec professionals.
Work of infosec professionals impacts other fields in technology and business. Ability to effectively communicate and influence others is crucial to the success of your work.
Security must become a business differentiator!
What to do:
Create a body of “essential business skills” that serves as curriculum for InfoSec professionals (refer to some of my work at my blog site rafeeqrehman.com)
Train team on key business concepts: value creation, negotiation, conflict management, influencing, effective communication, human experience, listening, collaboration, KPI (Key Performance Indicators), NPS (Net Promoters Score) and others.
Add a column to security controls databases/spreadsheets to monitor impact of a control on human experience (both +ve and -ve).
Recommendation 4
Take an inventory of open source software (standalone and libraries) and make it part of your vulnerability management program.
Why it matters:
Use of open source software is not bad in itself. Everyone uses open source software. The biggest examples are Linux and Apache server.
Many commercial software vendors use open source components but don’t properly disclose it.
Recent vulnerabilities (e.g. log4j) have far reaching impact.
What to do:
It is crucial to have an up-to-date inventory of all open source software, whether used as standalone products or embedded as a library inside a product. We can’t manage if we don’t know its existence.
Require your software vendors to provide you with a list of all open source libraries and their versions embedded into their products.
Make this list part of the vulnerability management program. Monitor release of new vulnerabilities and patches for your inventory of open source software components.
Recommendation 5
Build team expertise in technology fields including machine learning (ML) models, model training, API security, service mesh, containers, DevSecOps.
Why it matters:
Business enablement requires InfoSec professionals to be on the forefront of innovation and provide guidance on how to utilize emerging technologies (or risk being a roadblock for innovation).
Security professionals must learn new technologies, identify use of these technologies inside their organizations, and proactively build policies and standards for the use of these technologies.
What to do:
As an InfoSec leader, Identify emerging technologies relevant to your business and encourage your teams to build expertise.
Allocate budget for training or incentives for self-learning.
Some technology areas are a must for every security team. These include basic understanding of machine learning (ML) models, how ML models are trained, modern Cloud application architecture, service mesh, containers, and DevOps.
Recommendation 6
Maintain a centralized risk register. Even better: integrate into your enterprise risk management program. Track risk for technology, insiders, processes, third parties, compliance and skill gaps.
Why it matters:
Risk management is a key component of any reasonable security management program, yet many organizations don’t have a good idea about their overall risk.
Corporate boards and business leadership need InfoSec leaders to get better at communicating Cyber risk.
Cyber insurance companies’ demands for better risk management practices are only going to increase.
What to do:
While proper quantification of risk is a great aspirational goal, many organizations can start with simple methods to track risk.
Account for all major areas (technology, insider threat, process gaps, third parties, skill gaps in security teams, compliance, use of open source software) and adopt a consistent methodology for risk identification, assessment, prioritization and treatment.

Recommendations provided here are not professional advice. Cybersecurity is a complicated matter and actions may differ significantly based upon how the overall ICT networks and applications are designed and implemented. A thorough assessment of network and applications is necessary for specific recommendations.
NOTE: An updated version of CISO MindMap has been published here.
Let me start with the quote from last year: Most people outside the Cybersecurity profession don’t fully realize and appreciate the complexity of a security professional’s job. Since 2012, CISO MindMap has been an effective educational tool and has enabled professionals to design and refine their security programs. Here is the latest and updated CISO MindMap for 2022 with a number of updates and new recommendations for 2022-23.
CISO MindMap 2022

What has changed?
With time, the responsibilities of security professionals are only increasing. Why? Technology is changing fast, bringing new ways of doing business, continuous adoption of Cloud, and many emerging technologies. Not only the Infosec professionals are “expected” to deeply understand these technologies, but also provide policies/guidance on how to secure them. For this reason, every year you find a few new things on the CISO MindMap. Like every year, few things are added, changed or removed from the MindMap depending upon their relevance. Changed items are marked in red for your convenience.
Other changes include but not limited to:
Remove duplicates
Merge branches with overlapping functions
Add NIST CSF references at high level, where possible.
In some cases more defined/accepted terminology has emerged. For example, Cloud Security Posture Management (CSPM) is a widely accepted term now. As a result, I have replaced some Cloud Security items with CSPM.
Expiration Date – A common issue is that many professionals still have older CISO MindMap copies. I added an “expiration date” to let people know when they should stop using a particular version. The expiration date for the 2022 version is the end of June 2023. The next version will be published before the current version expires.
Recommendations for 2022-2023
I know you already get plenty of recommendations from your vendors, industry analysts and pundits, and other “experts”. You also know that many of these recommendations may have some vested interests and/or biases. I make my own recommendations as a practitioner every year and try to be objective, avoid the hype, need for adoption in the next 12-18 months, and solely focus on what data and research shows. However, it is still my interpretation of data and facts and I may have my own unintended biases even with all objectivity and an evidence-based approach. For me, the most difficult part while making these recommendations is to pick as few as I can. The following list is longer than what I would like it to be but hopefully it would give you a few things to think about. The followers of MindMap would quickly realize that some of these are the same as of last year.
Re-evaluate ransomware defenses, detection and response capabilities, perform a business impact analysis and identify critical processes, applications and data.
Reduce/consolidate security tools/technologies and vendors. More tools don’t necessarily reduce risk but do add the need for maintaining expertise on security teams.
Train staff on business acumen, value creation, influencing and human experience to serve business better. I can’t emphasize this enough.
Take an inventory of open source software (both direct and indirect use) and make it part of your vulnerability management program.
Build team expertise in technology fields including machine learning (ML) models, model training, API security, service mesh, containers, DevSecOps.
Maintain a risk register.
I am eager to listen to your viewpoint on these recommendations, why or why not!
How to use CISO MindMap?

Many career paths in information security are well-established and new ones are emerging. Although there are specific skills required for each career path, some skills are fundamental and essential for each of these career paths. These essential skills are listed below and anybody wishing to be successful in information security should build a strong foundation in all of these.
Foundational information security principles
Confidentiality, Integrity and Availability (CIA), fundamental security architecture, least privileges, need to know, access controls,
Operating Systems and Cloud – Linux/Unix, Windows, Cloud, Mobile operating systems. Fundamental hardening methods for these operating systems
Networking and application protocols
Very good knowledge of common Internet and application protocols TCP/IP, DNS, HTTP, SMTP, SSH, routing protocols etc.
Knowledge and hands-on practice for routers and switches, packet capture tools, nmap, curl, and other tools to be able to know what is happening on the network.
Scripting and Programming
Shell scripting, Python, understand how web applications are built, HTML, JavaScript, SQL/Databases
Encryption technologies – PKI concepts, TLS, data security
Whether it is opening a firewall port, relaxing a permission on an S3 bucket, or mailing a confidential document to a private email address, people often try to circumvent information security controls with a “good intention of getting things done”. Unfortunately, the same results in data breaches repeatedly, many of which could be avoidable. One of the reasons is how the CIA (Confidentiality, Integrity, Availability) triad is used by information security professionals to design security controls. An overemphasis on the CIA triad makes information security professionals forget the harm some of these controls may do to human experience and create an implicit temptation for others to circumvent those controls. It is time to recognize this issue and make modifications to remediate it.
What is the CIA triad of information security?
The triad is built around fundamental principles and objectives of any information security program. It has done an excellent job to explain information security to newcomers to the field and explain security objectives to others.
The CIA triad of information security
In summary:
Confidentiality is about ensuring that information stays protected and is only disclosed to people who need to know it.
Integrity is built around the idea that no unauthorized change is made to the information, systems and networks to protect confidence in the accuracy of the information and other IT systems.
Availability – The information, systems, networks and other resources stay available in the face of cyber attacks, natural disasters, and other unforeseen events.
There are numerous articles written on this topic and I am not going to go into detail except stating one crucial aspect: A balance is needed in all three parts of the triad as overemphasis on one can impact the others. For example, over-protection of confidentiality may adversely impact availability.
Without good human experience, the triad is failing the profession
One way or the other, directly or indirectly, ultimately people have to interact with security controls designed by the information security departments. As we are painfully aware of the fact that many times security teams are considered a roadblock rather than enabler of the business because of these controls. I am sure many of us have heard quotes like “security is where ideas go to die”. If you dig deeper into this notion and ask questions to explore why it is so, you will easily come to realize that the missing element in designing security controls is forgetting the human experience.
With very good intentions and without any disregard to human experience, sometimes security professionals still get carried away with strict implementation of the CIA triad in the design of security controls. The reason is that the human aspect is not part of basic principles and objectives (Confidentiality, Integrity and Availability). Since the CIA triad is always the focus of designing these controls, it is time to change it.
How can we redefine the information security triad?
While there could be a number of different ways to bring the notion of human experience into the CIA triad, one of the simpler ones can be putting the human experience at the center as shown in the diagram below.
Another option is to change the triad to a quartet. The importance of factoring in the human experience is high enough to make this change.
Now just changing the triad one way or the other is not enough unless it is accompanied by making it part of security training and defining what the human experience means and how it is impacted, positively or negatively, by certain actions. Major security certification organizations like ISC2, ISACA and others also need to make it part of the learning objectives for certifications exams.
Continuous improvement to the information security profession based upon what we learn from our experiences is an essential part of the progress. Lack of considerations for the human experience is a deficiency in the current state of affairs and it needs to be addressed, starting with fundamental change to the information security triad.
Six fundamental models that always fill my personal and professional life with joy, pleasure and satisfaction
Do the right thing, always – This is my first model of a joyful life, explained to me by a school senior friend. If you do this, you will never regret anything from the past, career choices, business decisions or personal relationships. It takes a lot of courage, but you will have a contented heart all the time.
Create value for people – “Your value” is directly proportional to the value you create for others. Measure your actions by how much they benefit others, whether it is a business meeting, a family dinner, or social media post. Always serve the people around you.
Embrace imperfection – There is no perfect time to launch a product, start a business, pursue a degree, or change career. You will never have perfect information to make important decisions. Embrace imperfection, “good enough” is much better than “perfect”.
Be generous to people – Be generous in your praise of people, in sharing credit, in giving favors. Be a giver. Be generous with people who disagree with you. Giving favors is the best investment for your career and your personal life. The best thing is that you know when you are generous.
Simplify everything – Complexity is the biggest enemy at work, home, in relationships, and with friends. Be simple, do simple things, have simple ideas, simplify things for people. Be single threaded to improve productivity. Use images, diagrams, and analogies to explain complex things.
Fail often – Fear of failure keeps people from achieving great things and miss career opportunities. Fail, because if you have not failed in a long time, you have very likely missed many opportunities. Overcome the fear of failure, you don’t have to prove anything to anyone. Abandon your comfort zone.
While many people and organizations have been praised for their philanthropic work and poverty alleviation, the open source movement does not get the credit it deserves. I would argue that no other work comes even close to what the open source software movement contributed and achieved. How? Let me explain just a few points.
Access of modern operating system for Universities
Before Linux was a thing, a vast majority of universities in the developing world could not afford purchasing expensive multi-user operating systems and the machines they used to run. People remember how expensive Sun, IBM, Vax and other systems (hardware and software) used to be. As a result, it was very difficult for students of these universities to gain modern skills, get high paying jobs in the emerging software industry, and pull their families out of poverty. Linux changes much of it. It was free, it ran on cheap commodity hardware, and it opened a world of new possibilities for millions.
Startups and software development
The open source software packages, compilers like GNU, and other development tools made software development accessible and enabled common people to build software applications and start their own businesses. It made innovation and large scale job creating possible.
Enabling the Internet
The Internet would not be what it is if there were not the Apache web server, open source databases, and other tools that run the core of the Internet engine. Think about the opportunities and wealth that has been made possible through the Internet, thanks to open source software that runs most of the Internet services.
AI/ML and emerging technologies
Open source software libraries for Artificial Intelligence (AI) and Machine Learning (ML) are core to the expansion of this field as well as other technologies that fuel IoT, Cloud, and DevOps.
Today a large number of Internet connected devices run on some version of Linux, most of the Internet servers run Linux. Same is true for mobile devices. The credit goes to a large number of enthusiasts building open source software and organizations protecting the movement from legal challenges. The open source software is the engine of innovation, human progress, and wealth generation. Directly or indirectly it continues to pull people out of poverty. More than anything else, it is changing lives for many and making the playing field level for everyone.

There are many reasons that make Secure Access Service Edge (SASE) an appealing concept. Major among these are moving from corporate data centers to the Cloud, need to work from anywhere, reducing complexity, and use of applications delivered as SaaS. The SASE hype is at its peak and all major security &network vendors are embarking on the SASE train. However, there are many factors that can derail this train and it is yet to be seen if market is ready for large scale SASEE adoption.
Factors to Consider
SASE is not a single technology. One of the objectives is to provide a combination of many capabilities into a single platform. However, reliance on single platform has its own side effects. Any major security issue with a SASE vendor could create problems. For example, in the face of a major security incident, while it is plausible to shutdown part of IT infrastructure, turning off a SASE platform may mean shutting down the business.
Many small businesses have limited budgets/IT staff with no separation of security and network and could be good target for SASE adoption. However, any sizable medium and large businesses have separate security teams. People who have worked in corporate world for a long time, are well aware of cultural issues and dynamics that play a key role between security and network teams. How these two cultures come together is yet to be seen.
Adherence to the key security concepts including separation of duties, defense in-depth with multiple technologies, using technology components that provide a single function, still need some reconciliation with the notion of convergence and use of a single platform.
Why it matters?
To implement a SASE platform, key decision makers need to fully evaluate the factors mentioned above, keeping in view risk factors, cost, and complexity. The alternate to using a single SASE platform is combining best capabilities from multiple vendors.
Who should care?
There are multiple parties who have some stake in SASE decision making. These include but not limited to:
CISO – manage risk
CFO – save money
CIO – manage complexity and budget
What is next?
A “complete” SASE platform does not exist yet. Businesses need to make careful evaluations of vendor offerings, avoid “me-too” solutions, and think in the long-term as adopting a SASE platform.
Most people outside the Cybersecurity profession don’t fully realize and appreciate the complexity of security professionals’ job. I have been publishing and updating this MindMap for almost a decade, not only as an effective educational tool but also to enable professionals to use this MindMap for designing and refining their security programs. Here is the latest and updated CISO MindMap for 2021 with a number of updates and new recommendations for 2021-22.
The responsibilities of security professionals are only increasing and CISOs are finding themselves in the middle of more things than they wish to be. Why? Technology is changing fast, bringing new ways of doing business, continuous adoption of Cloud, and ever-expanding uses of machine learning (and AI in a broader sense). Infosec professionals are “expected” to not only understand all of this but also provide policies/guidance on security of these technologies. For this reason, every year you find a few new things on the CISO MindMap. This year, I have also reorganized/moved a few items to more appropriate sections. So:
Items in red color are new that did not exist last year.
Items in blue color are not new, they are just rearranged in a different section of the MindMap.
I hope this color coding will help you understand what has changed.
Recommendations for 2021-2022
I know you already get plenty of recommendations from your vendors, industry analysts and pundits, and other “experts”. You also know that many of these recommendations may have some vested interests and/or biases. I make my own recommendations as a practitioner every year and try to be objective, avoid the hype, and solely focus on what data and research shows. However, it is still my interpretation of data and facts and I may have my own unintended biases even with all objectivity and an evidence-based approach (by now some of you may have figured out that I am not a machine, although the Age of Spiritual Machines has long been predicted and is on the horizon). For me, the most difficult part while making these recommendations is to pick as few as I can. The following list is longer than what I would like it to be but hopefully it would give you few things to think about.
Re-evaluate your ransomware defenses, do a business impact analysis, especially in areas where ransomware may impact the physical world and human safety.
Reduce/consolidate security tools/technologies and vendors (less is more in many cases).
Monitor Cloud mis-configurations in real time and at machine speed.
Adopt borderless network strategies (SASE, Zero Trust, and/or whatever you want to call it).
Think about cooperative/collaborative SOC strategy.
Train staff on business, ML models, model training, service mesh, containers, DevSecOps.
Plan for government shutdown of a critical software or service provider due to security issues and supply chain attacks (hope this never happens but supply chain attacks in the past 12 months warrant need for preparedness).
Item number 5 above is a long-term consideration and is not really a new or earth shattering idea. However, it is something to consider seriously for sustainability and to remove some of the insanity in security operations. If you don’t agree, I am eager to listen to your viewpoint and why.

Secure Access Service Edge or SASE is a relatively new concept. The goal is to connect users from anywhere to applications, data and services hosted in any place (Cloud, corporate data centers or Software-as-a-Service platforms). The basic idea is to simplify technology infrastructure by combining commonly-used network and security services in a single platform and deliver this service from the Cloud.
What would it take to implement a SASE strategy?
Many vendors have started creating their “SASE platform” that include technologies such as SD-WAN, Cloud based firewall, Zero Trust networking, Cloud Access Security Broker (CASB), Secure Web Gateways (SWG) and others. However, a SASE strategy goes beyond technology platforms and must include the following four components:
SASE technology and platform that integrates individual SASE components and is delivered from Cloud.
The underlying network transport (Dedicated internet, broadband, wireless, private network, etc.) that enables SASE.
Managed network service combined with a SASE platform to provide a fully managed SASE service.
Threat monitoring, detection, and response
Why should you care?
At this point, the SASE market is evolving and almost all vendors are struggling to build their “SASE story”. Businesses, who are consumers of these platforms, are also confused about their long-term strategy and which vendor to pick from an evolving “me-too” marketplace.
Which SASE providers are likely to succeed?
Businesses who rely on their technology partners for managed services will tend to look at network/telecom service providers (to acquire all four components of a SASE strategy as listed above). Businesses who manage their network and security internally are most likely to go with SASE vendors that focus on user experience and simplicity through a common management platform (single pane of glass) that provides integrated SASE management and monitoring options.
