What Does The Word Security Mean In The Field Of Information Technology?

Information Technology (IT) Security Refers To The Methods, Tools, And Personnel Used To Defend An Organization’s Digital Assets. 

IT security aims to protect these assets, devices, and services from disruption, theft, or misuse by unauthorized users, otherwise known as threat actors.

These threats can be external or internal and malicious or accidental.

Physical security

Physical security protects people, hardware, software, network information, and data against physical actions, intrusions, and other events that can harm an organization and its assets. Protecting the physical security of a business means protecting it from threatening factors and natural disasters such as fires, floods, earthquakes, and weather conditions.

A lack of physical protection can compromise the servers, devices, and tools that support business operations and processes. It is said that people in the group are a large part of the threats related to physical security.

Theft and vandalism are examples of human threats that require physical security solutions. Material security breaches don’t necessarily require technical knowledge, but they can be just as dangerous as data breaches.

Physical security has three parts:

  1. Access control
  2. Supervision

The success of an organization’s physical security program depends on the practical implementation, maintenance, and updating of each of these components.

Access control

Controlling access to office buildings, research facilities, laboratories, data centers, and other locations is critical to physical securityAn example of a physical security breach is an attacker entering an organization using a universal serial bus (USB) flash drive to copy and steal data or inject malware into systems.

Access control aims to record, monitor, and limit the number of unauthorized users interacting with sensitive and confidential physical assets. Access control can be as simple as barriers such as walls, fences, and locked doors. Physical identification is a great way to authenticate users trying to access devices and areas reserved for authorized personnel. Badges and critical codes are also part of an effective physical access system.

More sophisticated methods of access control include various forms of biometric authentication. Fingerprint and facial recognition are two examples of typical applications of this technology. These security systems use biometrics or unique biological characteristics to authenticate authorized users.

Supervision

Testing

Information security

Infosec includes the following groups of security technologies:

Concepts and principles of information technology security

Some basic concepts form the basis of information technology security. Some of the most important ones are as follows:

Application Lifecycle Management: This protects all phases of the application development process by reducing the number of bugs, design flaws, and configuration errors.

Defense in depth: A strategy that uses multiple countermeasures simultaneously to protect information. These methods include endpoint detection and response, antivirus software’s response to threats, and countermeasures against illegally installed devices. Defense in depth is based on the military principle that it is difficult for an enemy to penetrate a multi-layer defense system rather than a single layer.

Patch management and updates:

The Codes to fix problems in applications, operating systems, and firmware provided by the manufacturer.

Principle of Least Privilege: This principle strengthens IT security by limiting user and application access to the lowest level of access rights required to perform their tasks or functions.

Risk Management: Identifying, assessing, and controlling security risks that threaten an organization’s IT environment.

Vulnerability management: With this approach, security managers identify and classify vulnerabilities to minimize their number in the infrastructure and reduce security weaknesses in information technology.

The mentioned items are some of the essential concepts and principles of security and information technology. However, combining all these security principles does not guarantee 100% that an organization’s IT infrastructure is entirely secure. Cyber ​​threat is a significant problem facing every IT security manager and business. However, organizations can defend against physical and infosec security threats by deploying a comprehensive security strategy.

Cyber ​​security vs. infosec

Due to the intersection of information security with endpoint, IoT, and network security, it cannot be easy to separate information security from cybersecurity.

However, there are distinct differences. One difference is geopolitical issues. Cybersecurity can refer to defense mechanisms that protect a country or a government’s data from cyber warfare. It is because cyber security involves protecting data and related technologies from threats.

On the other hand, information security focuses on ensuring the availability of information, confidentiality, and integrity.
