Cybersecurity is the practice of protecting systems, networks, and data from cyber threats. Here's a detailed breakdown:
1. Core Concepts of Cybersecurity
-
Confidentiality – Ensuring sensitive data is accessible only to authorized users.
-
Integrity – Maintaining the accuracy and reliability of data.
-
Availability – Ensuring systems and data are accessible when needed.
2. Types of Cyber Threats
-
Malware – Viruses, worms, ransomware, and spyware that harm systems.
-
Phishing – Fraudulent attempts to obtain sensitive information.
-
Denial-of-Service (DoS) Attacks – Overloading systems to make them unavailable.
-
Man-in-the-Middle (MitM) Attacks – Intercepting communications between users.
-
Zero-Day Exploits – Attacks targeting undiscovered vulnerabilities.
3. Cybersecurity Domains
-
Network Security – Protecting networks from unauthorized access.
-
Application Security – Securing software from vulnerabilities.
-
Cloud Security – Safeguarding cloud-based services and data.
-
Endpoint Security – Protecting individual devices like computers and smartphones.
-
Identity & Access Management (IAM) – Controlling user access to systems.
4. Cybersecurity Best Practices
-
Strong Passwords & Multi-Factor Authentication (MFA) – Enhancing account security.
-
Regular Software Updates – Patching vulnerabilities to prevent exploits.
-
Data Encryption – Securing sensitive information from unauthorized access.
-
Security Awareness Training – Educating users on cyber threats.
-
Incident Response Planning – Preparing for cyberattacks and breaches.
5. Cybersecurity Regulations & Compliance
-
GDPR (General Data Protection Regulation) – Protects user data in the EU.
-
HIPAA (Health Insurance Portability and Accountability Act) – Secures healthcare information.
-
ISO 27001 – International standard for information security management.
-
NIST Cybersecurity Framework – Guidelines for managing cybersecurity risks.
