Updated on:

I’ve witnessed first-hand the damage caused by cyber threats. But here’s the truth: cybercriminals are advancing their tactics faster than we can keep up with. That’s why I’m here to shed some light on the three key branches of cybersecurity that will help protect you and your business from such attacks.

The world of cybercrime is an ever-changing game, one where cybercriminals are constantly evolving their operations. But with the right knowledge, resources, and tools, you can safeguard yourself against these damaging attacks.

So, join me as I unveil the three key branches of cybersecurity. Trust me; it’s worth your time.

What are three major divisions of security?

The three major divisions of security are essential components of any comprehensive security program. Each plays a critical role in safeguarding an organization against both internal and external security threats. Let’s take a closer look at each of these categories:

  • Operational Security: This aspect of security involves the implementation of measures to protect computer systems from unauthorized access, destruction, or disclosure. Examples of operational security measures include password policies, network segmentation, intrusion detection systems, and firewalls.
  • Management Security: This refers to the policies and procedures put in place by upper management to guide the behavior of employees and reduce the risk of security breaches. Examples include employee background checks, access controls, and security awareness training.
  • Physical Security Controls: These control measures include physical barriers, such as locks, surveillance cameras, and security personnel. There are also environmental controls, such as climate controls, backup generators, and smoke detectors, to protect an organization’s physical assets.
  • All of these types of security work in conjunction to provide comprehensive security control, both online and in the physical world. It is essential to remember that security is an ongoing process, and a combination of measures must be put in place to guard against new and evolving security threats.

    ???? Pro Tips:

    1. Physical Security: This division focuses on securing tangible assets such as buildings, employees, and equipment. Physical security includes measures such as surveillance, access control systems, and security personnel to prevent unauthorized access and theft.

    2. Information Security: This division involves protecting sensitive information such as personal data, financial information, and intellectual property. Information security measures include encryption, firewalls, and antivirus software, patching vulnerable software, and training employees to detect and prevent cyber attacks.

    3. Operational Security: This division deals with the overall security posture of an organization, including risk management, incident response planning, and cybersecurity framework adherence. Operational security allows organizations to identify threats and implement proactive measures to minimize them.

    4. Have a comprehensive security policy in place: A security policy is a document that outlines an organization’s security measures, expectations, and goals. It should encompass all the three divisions of security, and it should be easily accessible and understood by all employees.

    5. Train your employees: Employees are often the weakest link in any security program. Regular training sessions can educate them on the latest hacking techniques and phishing scams and how to identify and report security incidents. This helps reduce the risk of an employee accidentally causing a security breach.

    Overview of Security Control Categories

    Security control is a crucial aspect of any organization that globally works with sensitive information that should not be exposed. A company’s reputation and prosperity will decrease if their information is leaked, compromised, or stolen; therefore, it is essential to have a system in place to prevent any security breaches. There are three main categories or areas that comprise security control: Operational, Management, and Physical Security Controls. They function together to establish effective security measures and strategies that fulfill the requirements of safeguarding an organization’s data, systems, intellectual properties, facilities, and other assets. An integrated security approach that ensures the safety and protection of these assets is essential to avoid unexpected security breaches.

    Operational Security: Protecting Data and Systems

    Operational security is all about protecting a company’s data and systems from cyber-attacks, information theft, malware, and other risks. It consists of a set of policies, technologies, and procedures that offer effective control and protection over sensitive information. Three critical components of the operational security category include:

    Technology Restriction and Access Control: All employees’ system password resets, access specification, backup, and storage requests should be subjected to strict control. The access granted to sensitive information should be limited only to necessary employees to avoid data theft or leaks.

    System Auditing and Activity Monitoring: Auditing entails the review of the recorded data, while activity monitoring involves 24/7 surveillance of sensitive data and systems. These techniques ensure that all system activity is continually monitored for unexpected transactions and files accessed by unauthorized users.

    Incident and Response Planning: Organizations should have a systematic plan in place in case of a security breach or cyber-attack. The plan should include reporting protocols to prevent further damage and appropriate response time.

    Management Security: Decision Making and Planning

    Management security functions as the core framework for all security strategies and policies. It is responsible for ensuring that all security approaches align with the company’s mission and objectives. It consists of decision-making processes, policies, strategies, and procedures that guarantee the efficient execution of security control. Management security includes the following components:

    Security Policy Formulation: The security policy outlines the rules and regulations of the security measures that a company implements. Security policies should be updated regularly to adapt to new security threats.

    Security Planning: Every security planning should outline the approach taken to control access to sensitive data and systems.

    Security Training: Training employees regarding security risks is an essential component of management security. Employees raised in security awareness training are likely to detect and report threats that could potentially harm the organization.

    Physical Security Controls: Securing Facilities and Assets

    Physical security controls’ primary function is to safeguard the company’s premises, assets, inventory, and other valuables. The following are essential components of physical security controls:

    Active Surveillance and Access Control: Access to sensitive information should be restricted to authorized personnel only. Enabling physical security mechanisms will help prevent unauthorized access to buildings.

    Security Alarms and Locks: Reliable security systems are essential to protect the physical facilities and equipment of an organization. They also help to safeguard any backup systems, which could contain essential data that should also be protected.

    Location Based Data Management: Depending on the geographical location of the organization, sensitive data should only be accessible to specific locations or IP addresses.

    Threat Assessment and Risk Management

    Threat assessment and risk management are fundamental operations in every security system. These two components help identify potential security risks that could lead to data or asset compromise. Risk management enables companies to assess the potential consequences of these breaches, establish mitigation strategies and prioritize their responses to avoid unexpected occurrences.

    Implementation of Security Policies

    Effective security policies should be implemented across all aspects of an organization to combat security threats. Management teams should ensure that these policies are understood and implemented by all employees. The solutions implemented should feature suitable monitoring, assessment, and reporting mechanisms to ensure that any malicious security breaches or risks are reported promptly and efficiently.

    Importance of Interdisciplinary Collaboration in Security Control

    Security control is not a one-person job, but it requires collective efforts from different departments within an organization. Collaboration is key, especially regarding the sharing of intelligence and threat assessment data. Security teams should also ensure close collaboration with the company’s management and other teams responsible for system access control, client information, and financial data control.

    In conclusion, an effective security control system should cover all aspects of an organization’s operations. The use of an integrated security approach that involves Operational Security, Management Security, and Physical Security Controls will help ensure that an organization’s operations are safe from data theft, particularly in an era where the use of advanced technology has become rampant. Companies should emphasize the importance of committing resources in implementing these security measures to ensure that their data and assets remain safe and secure.
