Overview of IT Security and Cybersecurity

​

IT security and cybersecurity are critical areas that aim to protect digital systems, networks, and data from threats and damage. It involves identifying, preventing, and responding to security risks, as well as ensuring continuity and trust in digital environments.

Threat Images: What are IT Security Risks?

​

IT Security Risks are potential threats that can lead to damage to the digital assets of organizations and individuals. Threats can be divided into different categories:

 

Malware (malicious software):

Examples: Viruses, Trojans, ransomware, and spyware.

These programs are created to steal data, encrypt systems for extortion, or sabotage businesses.

 

Phishing and Social Engineering:

Attackers use fake emails, SMS, or other methods to trick individuals into revealing sensitive information such as passwords or credit card details.

 

Network Intrusion:

Hackers exploit weaknesses in networks to gain unauthorized access to systems. This includes "Man-in-the-Middle" attacks and DDoS attacks.

 

Insider Threats:

Risks that arise from employees or others with internal access, intentionally or unintentionally.

Zero-day Vulnerabilities:

Vulnerabilities in software that have not yet been discovered or patched by the vendor.

 

Physical Threats:

Examples: Theft of hardware, natural disasters affecting data centers, and physical tampering with systems.

Basic Security Principles

 

To effectively manage IT security risks, some basic principles should be followed:

Confidentiality:

Protect sensitive information from unauthorized access. Examples: Use encryption and strong authentication mechanisms.

Integrity:

Ensure that data is not altered or manipulated by unauthorized parties. Examples: Use of checksums and version control.

Availability:

Ensure that systems and data are always available to authorized users. Examples: Implement redundancy and regular backups.

​

Privilege minimization:

Restrict user and system access to only the resources required to perform their tasks.

Risk assessment and management:

Identify and evaluate potential threats and implement measures to mitigate risks.

 

Security education:

Inform users and employees about IT security risks and best practices.

The role of cybersecurity in society

Cybersecurity is crucial for protecting digital infrastructures that are fundamental to society. Its role is becoming increasingly important as more processes are digitized and dependence on the internet grows.

Critical infrastructure protection:

Sectors such as energy, transportation, healthcare, and banking rely on cybersecurity to ensure the reliability and security of their services.

 

Economic stability:

Cybersecurity protects businesses from financial losses resulting from data breaches, intellectual property theft and other cybercrimes.

 

National security:

Protection against cyber warfare and espionage is central to the security and sovereignty of countries.

 

Protection of individuals’ privacy:

Cybersecurity is essential to protect personal data from being stolen or misused, especially with the introduction of laws such as the GDPR.

 

Promoting innovation and growth:

A secure digital ecosystem enables the development of new technologies and services without fear of security issues.

 

Summary
​IT security and cybersecurity are not just technical issues, but also strategic and societal ones. By understanding the threat landscape, implementing fundamental security principles and recognizing the role of cybersecurity in society, we can create a safer and more stable digital world.
