It is also known as Cyber Threat Intelligence that allows an organization to collect information from a number of resources to analyze and isolate any potential cybersecurity threats.

The threats that are analyzed are acted upon quickly in order to minimize the potential cyber risks it carries.

  • Quantitative data collection: Collecting information on past and potential cyber threats. 
  • Assist other cybersecurity domains function better: Always used along with other cybersecurity domains.
  • Holistic protection to database: Can protect against internal and external cybersecurity threats.  
  • Bring out the efficiency in functioning: Can assist other cybersecurity domains function better.

6. Governance

The strategy of any organization to deal with potential and real cyber security attacks. Allows organizations to develop better cybersecurity measures.  

  • Governs different cybersecurity processes: Process of decision making and implementation of cybersecurity measures
  • Helps reduce cyber attacks: Risk analysis is aided with Governance and decisions can be taken on time
  • More cost efficient: Allows organizations to be more cost efficient by creating better rules and regulations in place
  • Better policy formulations: Aids in creating a better company policy on various aspects of internal and external security

7. End- user education

Allows employees to be better informed on data hacks and data losses. This will prevent unnecessary attacks in the first place or they will be able to identify risks in the first place themselves. 

  • Make everything secured: Gather more education on information security domains, which only deals with protecting information and information systems.
  • Everything is encrypted: Work through confidentiality, integrity and availability as a part of end- user education.
  • Include daily exercises to be more functional: Engage in cybersecurity tabletop exercises, training and information security education as part of end-user education.
  • More protected data: Better protection against data hacks and data losses with the right tools.

8. Physical security

The cybersecurity of any organization can run smoothly when the physical assets of the company are safeguarded. The cybersecurity systems need a secure physical location to operate as well.

  • Address the threat more directly: Growing complexity of physical cybersecurity can be addressed through physical security threat analysis 
  • No more threat from AI: AI and internet of things challenge physical cybersecurity as an ever growing threat
  • Physical damage is possible: Damage to physical assets can hamper people and property of the organization
  • Helpful for cyber teams: Cyber teams need to protect physical assets of the organization as well.

9. Career development

If cybersecurity and cyber attacks have become sophisticated, so has the demand for properly qualified cybersecurity personnel. It is important to have the right people on your team to ensure the best defense and services for your organization. 

  • Excel through various trainings: Get the right certifications, training and self- study the different domains, if you come across something new and different 
  • Be updated on the latest certifications: Getting the right certifications and being constantly updated through them like the CISSP (Certified Information Systems Security Professional) 
  • Be in the know of the best in your industry: Be on top of all new developments in cyber security
  • Learn the right hacking skills: Ethical Hacking is a great new cybersecurity certification that can actually help organizations.

10. Security architecture

A cost effective and efficient security architecture that would allow you to address the existing and potential threats that the organization may be under.

There are many categories that need to be taken care of in security architecture like legal aids, financial aid, risk management and many more.

  • Provide the right environment to cybersecurity team: Giving the cybersecurity team the right environment to ensure that the potential risks can be taken care of.
  • Logical implementation: Risk assessment and risk analysis in a logical manner that is deliverable and sustainable
  • Security architecture: Proper documentation of the creation of this security architecture and the steps that this domain takes on.
  • More efficiency in the process: Security architecture specifies the optimum conditions to take of all domains.
