What is IT Security?
IT security is about protecting digital information and systems from unauthorized access, sabotage, and cyberattacks. The focus is on safeguarding confidentiality, integrity, and availability.
How does IT Security work?
Protection is implemented across several layers:
- Network security: Firewalls, IDS (Intrusion Detection Systems), VPNs
- Device security: Antivirus software, patch management
- Data protection: Encryption, backups
- Authentication: Two-factor authentication (2FA) and Zero Trust models
Benefits of IT Security:
- Protection against intrusions
- Stable and reliable operations
- Compliance with regulations
- Increased trust from users and stakeholders
Challenges in IT Security:
- A growing and evolving threat landscape
- Technical complexity
- Balancing security with usability
Use Cases:
- Businesses and government agencies
- Industrial systems
- Resilience Hubs
- Events and temporary networks
