What is the 3 major division of security?

The actions that cyber security professionals do to defend a company are fundamentally shaped by security controls. The three basic categories of IT security controls are physical, administrative, and technical. Implementing a security control may have a preventative, detective, corrective, compensating, or deterrent-type primary purpose.

As with social engineering awareness training or rules, controls are also employed to protect people. Information confidentiality, integrity, and accessibility are in danger due to a lack of security safeguards. These dangers also affect an organization’s ability to protect its personnel and resources.

Security Control-what is it?

Security controls are precautions or remedies that are employed to lessen the likelihood that a threat may exploit vulnerability. For instance, putting in place corporate security awareness training to reduce the possibility of a social engineering assault on your network, users, and information systems. Risk mitigation is another name for the process of lowering risk. In this article, we are going to see about the kinds of security and the detailed description of these components in the upcoming session.

Risk Mitigation-what is it?

Although it’s nearly impossible to stop every threat, mitigation aims to lower risk by lessening the likelihood that a threat will take advantage of vulnerability. Several security control mechanisms can be implemented to reduce risk depending on:

  • The purpose of the safeguard or countermeasure.
  • The degree to which danger must be reduced.
  • The extent of the harm the threat is capable of causing.

Explain the three 3 key Security controls

Management Security

Management controls and management security are two different terms. Coherent rules, instructions, and practices are necessary for a secure environment. This section of security helps create plans so that the core operations won’t be harmed in the case of a security assault, in addition to safeguarding a company’s data and network.

Threat analysis, information classification or categorization, risk analysis, and management security are handled by these processes. Given that it affects the other two security divisions, including information security, this is quite significant.

Operational Security

Other kinds of security are Operational security. Operational security, which is also known as procedural security, was first applied by the military to prevent the public from learning sensitive information. This is a risk management procedure that requires managers to monitor business activities to ensure that any sensitive data does not get into the wrong hands. This security section is utilised by the private corporation to monitor social media sites in addition to inspecting the activities. Operational security steps include:

  • Determine what information is private or secret.

It must be able to gather and classify sensitive data, including financial accounts, customer data sheets, personnel details, product research, and other intellectual property. This data need to be the focus of resources to assure security.

  • Examine possible dangers.

Name any potential hazards that might be present in the business or organisation. These can include malicious insider threats, careless personnel, and furious employees who might try to steal sensitive information.

  • Investigate security flaws and vulnerabilities

Verify and evaluate the company’s current security. Ascertain whether there are any gaps or openings that could be quickly exploited to obtain sensitive data about the company.

  • Rate each vulnerability’s level of risk.

Ranking any vulnerabilities that are found based on various criteria, such as the likelihood of an attack, the degree of harm, the amount of labour required, and the turnaround time.

  • Construct defences

A plan is required to reduce and eliminate hazards while also minimising risks. An illustration would be upgrading the business’ hardware. Training staff to protect the company’s procedures and rules is another option.

All devices connected to the company’s network should have restricted access if operational security is to be established. Employee access must be restricted to a minimum to safeguard important company information. Automation of tasks can reduce the need for human intervention. To have a sound security stance, there must be quick intervention and a recovery strategy.

Physical Security

The owner of a contemporary business today needs physical security. Threats might emerge from hackers and other corporate breaches because everything is dependent on technology. Data, hardware, and personnel must be protected physically from attacks that could seriously harm business operations. These kinds of security are also necessary to protect personnel. Fraud, theft, and vandalism are just a few examples of threats. As a result, defences must be put in place to prevent incursion into a company’s:

  • Access control
  • Training
  • Website Design
  • Emergency response readiness
  • Intrusion Detection

The Physical Security Components

  • Deterrence 

They may be actual obstructions that prevent customers from entering the company’s facility. Video security cameras and access control systems are examples of technology. These all prevent unauthorised visitors from entering the business.

  • Detection

Physically securing the business requires more than deterrents can provide. Sensors, alarms, and other warnings assist in preventing intrusion into the firm. In this approach, when an attack is possible, detecting components aid in signalling for assistance.

  • Response 

When an intrusion or breach occurs, a physical security response, such as communication systems and emergency services, aids in responding.

  • Delay

Security systems are put in place in the workplace to slow down intruder entry. It is convenient to mitigate a company compromise thanks to access control systems and other clever security measures. This also keeps a business from suffering excessive losses.

The scope, which includes the policies, employees, and documentation procedure, must be determined before physical security planning can begin. Finding the main decision-makers in the company is also crucial. Making a list of the company’s various important access points is essential to keeping them safe. Choosing the monitoring and detecting systems that will be used in the firm is another task. The creation of a cybersecurity policy is also necessary for protecting sensitive technology records and data. Policy on encryption, hardware security, and employee training are a few examples of this.

Wrapping Up

To summarize from the above-given article we have seen all the vital division of security controls. And the kinds of security, includes Management Security, Operational Security and Physical Security.  Moreover, for a security professional, it is crucial to know more about these components and understand the risk factors behind this system.
