The 10 Domains of Cybersecurity

So here is my plan. 

I am going to hold 1-hour Webex meeting with all the Recruiters and candidates in one place so they can talk to each other. It starts by having you register for the meeting, Recruiters and Candidates alike.

Recruiters when you register, you will post the open jobs you are trying to fill. 

Candidates will register for a Basic or Advanced account. You will fill out a form where you post your resume, cover letter and letters of reference, social media, personal websites and so on.

The way this works is that the recruiters will add the jobs they want to list into the platform to be persused by the candidates. If the candidate marks a job they are interested in. The recruiter can also see all the candidates that are participating and mark their profile as interested. 

Then for the 1 hour call each candidate get the opportunity to do a 1 minute elevator pitch about themselves and each recruiters gets 1 minute to pitch their jobs.. You can then message message each other and set up a call to move forward with interviews.

The last 20 minutes of the call anyone on the call can ask questions of the group oveall or to another specific user on the system.. At the end of the call all of that motion transfer and broke me.

The Cost is FREE!!!!

Cybersecurity Industries and Domains

What, you might ask, are industries and domains within cybersecurity?  Simply put, industries are groups of related companies based on their primary business activities. Fields are specified spheres of knowledge and action within a discipline.

Why is it essential for those interested in a cybersecurity career to know the top industries and domains? Well, one reason is when you seek a cybersecurity job, it’s always good to know which industries are hiring the most professionals. Fields within cybersecurity are also crucial to know what knowledge is expected of you if you enter cybersecurity.

Industries in Cybersecurity

The U.S. Bureau of Labor Statistics (BLS) notes that, as of May 2019, the annual mean wage for information security analysts/cybersecurity professionals working in the U.S. was $104,201. The industries with the highest levels of employment for information security analysts/cybersecurity professionals are:

  • Computer Systems Design and Related Services
  • Management of Companies and Enterprises
  • Credit Intermediation and Related Activities
  • Management, Scientific, and Technical Consulting Services
  • Insurance Carriers

Industries with the highest concentration of employment for information security analysts are:

  • Monetary Authorities – Central Bank
  • Computer Systems Design and Related Services
  • Data Processing, Hosting, and Related Services
  • Telecommunications
  • Management of Companies and Enterprises

But what most people want to know is, what are the highest-paying industries for information security occupations? According to the BLS, they are: 

  • Residential Building Construction, where information security analysts earned an annual mean wage of $130,400
  • Semiconductor and Other Electronic Component Manufacturing, where they earned an annual mean wage of $127,360
  • Legal services, where the annual mean wage was $125,230
  • Automotive Repair and Maintenance, where the annual mean wage was $123,720
  • Securities, Commodity Contracts, and other Financial Investments and related activities, where their annual mean wage was $121,230

As you can see, these industries all pay well more than the average annual salary for cybersecurity professionals.

Another exciting consideration undertaken by the Infosec Institute is which industries are the biggest targets for cybercriminals. These industries especially need cybersecurity professionals, as they are more likely to experience cyber breaches and attacks than other industries. According to Infosec, they include:

  • Healthcare – In 2015, the healthcare industry experienced the highest number of data breaches. The consequences of each healthcare breach can cost healthcare institutions as much as $200 per patient record. Preventing these breaches, however, costs just $8 per record.
  • Manufacturing– This includes automotive, electronics, and pharmaceutical companies and is vulnerable to cybercrime. Cyberattackers think this is a rich industry; therefore, if they attack it, they expect larger payouts. Security compliance and risk management need much improvement within this industry sector.
  • Financial services– In 2014, the financial services industry experienced the most cyberattacks. They have since made more significant investments in cybercrime security awareness and prevention. However, this industry still experiences many attacks due to the ease of compromising their security systems.
  • Government agencies– Cyberattacks against government agencies receive a large amount of media coverage, making attacks on this industry relatively high profile. This is one draw to hackers to attack the cyber systems of government agencies. Government agencies are now engaging in more employee security awareness training, but more needs to be done.
  • Education—Hackers see the education industry as quite lucrative, containing much personal, financial, and contact information. Educational records can also be hacked to change identities and obtain employment opportunities. Cybercrime has declined some in the education industry, but it continues.

Domains in Cybersecurity

The International Information System Security Certification Consortium, otherwise known as (ISC)2, is a nonprofit organization that offers some of the leading training and industry certifications in cybersecurity. For years, the domains they cover within their Certified Information Systems Security Professional (CISSP) examination have been considered Certified Information Systems Security Professional (CISSP) examination have been considered to be the definitive cybersecurity domains. When they updated the CISSP certificate structure in 2015, the domains were changed from 10 to eight. These eight domains, which have been widely accepted within the cybersecurity community, are:

  • Security & Risk Management
  • Asset Security
  • Security Engineering
  • Communications & Network Security
  • Identity & Access Management

  • Software Development Security

Let’s examine each of these domains in greater detail:
