Are you ready? Let’s get started.

What is the structure of cybersecurity?

The structure of cybersecurity is determined by the National Institute of Standards and Technology Cybersecurity Framework, which sets out five fundamental “Functions.” These functions are designed to help organizations better identify, protect, detect, respond and recover from cyber threats. Let’s take a closer look at each of these functions and the corresponding actions that are taken within each one.

  • Identify: This function involves understanding the organization’s assets, systems, and networks, as well as identifying potential risks and vulnerabilities. The actions taken under this function include risk assessments, asset management, and the development of policies and procedures to manage and secure data.
  • Protect: The second function, Protect, involves implementing safeguards to prevent or mitigate potential cyber attacks. This includes activities such as access control and user management, security awareness training, and encryption of sensitive data.
  • Detect: The third function, Detect, involves identifying potential cyber security incidents as early as possible. This is done through monitoring of networks, systems and applications, as well as establishing intrusion detection and prevention systems.
  • Respond: The fourth function, Respond, involves taking action in response to a detected cyber security incident. This includes activities such as incident response planning, communication and coordination, and evidence collection and analysis.
  • Recover: The fifth function, Recover, involves restoring normal operations and services in the aftermath of a cyber security incident. This involves activities such as backup and recovery planning, system and data restoration, and risk assessment and mitigation.

    In summary, the National Institute of Standards and Technology Cybersecurity Framework defines the structure of cybersecurity based on five fundamental “Functions,” each of which is a set of actions designed to help organizations better identify, protect, detect, respond and recover from cyber threats. By implementing these functions and corresponding actions, organizations can improve their overall cyber security posture and better protect against cyber attacks.

    1. Develop a comprehensive understanding of the underlying technologies involved in cybersecurity such as firewalls, encryption, intrusion detection, and prevention systems.

    2. Establish a clear and well-defined cybersecurity policy that outlines the roles, responsibilities, and procedures that are to be followed in case of a cyber attack.

    3. Invest in the latest cybersecurity tools, software, and hardware to strengthen your organization’s defenses against malicious attacks. Regularly update and maintain these tools to ensure maximum protection.

    4. Design and implement a cybersecurity awareness training program for all employees to educate them about emerging threats and best practices to protect themselves and the company’s assets.

    5. Continuously monitor and evaluate your security infrastructure to identify vulnerabilities and respond promptly to security incidents, breaches, and other external threats. Regularly conduct security audits and penetration testing to assess the effectiveness of your cybersecurity measures.

    Introduction: Understanding the Framework of Cybersecurity

    Cybersecurity, at its core, is the practice of ensuring the confidentiality, integrity, and availability of information in the digital realm. The increasing importance of digital information in every aspect of our lives has led to a corresponding increase in the number and sophistication of cyber attacks. To counter these threats, cybersecurity professionals use a framework of five core functions: Identify, Protect, Detect, Respond, and Recover. This framework provides a foundation for understanding the various aspects of cybersecurity and how they work together to create a comprehensive defense against cybercrime.

    Function: Identifying Cybersecurity Risks and Vulnerabilities

    The first function of the cybersecurity framework is Identify, which is just what it sounds like. This function involves identifying and documenting the various systems, assets, data, and capabilities that are associated with an organization’s information and digital operations. It is essential to understand the characteristics and value of these assets to determine which require protection. Organizations, regardless of size, must recognize their vulnerabilities and how they regularly check for new and emergent ones.

    This function requires the documentation of policies and procedures that include identifying the risks associated with the organization’s infrastructure and assets. The policies and procedures must also include how to report potential risks/vulnerabilities and mitigating against them. The Identify function is crucial because it lays the groundwork for the entire cybersecurity framework

  • until you know what you’re protecting and where the risks are, it’s impossible to implement any security measures effectively.

    Function: Protecting Against Cyber Attacks and Threats

    The Protect function builds on the information gathered in the Identify function to implement security strategies to protect against potential attacks. The Protect function is related to both technology and user education. There are several methods and techniques that can be implemented to protect assets and infrastructure, including:

    • Regularly applying security patches to software and systems to keep them up-to-date and free of identified vulnerabilities
    • Implementing firewalls and access controls to protect against unauthorized access
    • Providing user education and training to avoid phishing, social engineering, and other tactics used against users.
    • Regular backups
    • Strong passwords

    This function is essential because it provides the organization with a comprehensive understanding of the security measures necessary to implement, and how best to implement them.

    Function: Detecting Cybersecurity Breaches and Incidents

    While identifying and protecting against threats is essential, it is equally important to have methods in place to detect when an attack is happening or has happened. This is the third function of the cybersecurity framework: Detect. The Detect function involves monitoring systems and data for unauthorized access, anomalies, and incidents that may indicate a breach. This function involves analyzing logs and network traffic to detect when unusual activity is taking place

  • and stopping it before it causes damage.

    The Detect function includes employing a Security Information and Event Management (SIEM) tool to get a real-time or near real-time view of network operations. SIEM analyzes security alert data, network traffic, logs, and Intrusion Detection/Prevention Systems (IDS/IPS). With proper Detect functionality in place, organizations will be better able to spot malicious activity and prevent it from doing sustained damage.

    Function: Responding to Cybersecurity Incidents and Attacks

    The fourth function is Respond. Unfortunately, even with adequate detection measures in place, cyber attacks can still occur. The Respond function refers to the organization’s reaction to an attack or incident. This response may include procedures for isolating affected systems, shutting down the environment altogether, or taking action to prevent the attack’s spread.

    A vital role function in the Respond function recognizes the legal and ethical responsibilities that the organization has to both its users and the broader community where it operates. Such procedures must be in place to ensure cooperation with forensic investigators, and the organization should have a well-defined process for notifying customers and stakeholders of the incident’s scope and implications.

    Function: Recovering from Cybersecurity Attacks and Incidents

    Even with an adequate response plan in place, the damage from a cybersecurity event may have a lasting impact. The Recover function focuses on returning systems and data to their previous state as soon as possible. This function is responsible for restarting affected systems and restoring backup systems to ensure continuity of service. At the same time, it performs further analysis to understand what occurred, leads to the incident, and how the incident can be prevented from happening again in the future.

    Conclusion: The Importance of Implementing a Comprehensive Cybersecurity Framework

    The five functions of the cybersecurity framework outlined here provide a foundation for any business or organization to secure its digital operations. Recognizing the risks and vulnerabilities associated with unique systems/assets is the first step on the path to creating a reliable cybersecurity posture. Protecting against threats by implementing a variety of techniques, analyzing all traffic, and being alert through SIEM will help contain any breaches. And, to recover faster, developing comprehensive plans for dealing with events such as cyberattacks and having a strategy for rebuilding or reconfiguring operations. By keeping these principles in mind and implementing the cybersecurity framework, organizations will help keep themselves and their users safe. Taken together, these five functions provide a framework for the development of an overall comprehensive and robust cybersecurity program that is essential in today’s digital-centric business environment.
