Network Security

Network security describes the protection of IT networks against unauthorized access, attacks or data loss.

What does network security mean in detail?

Technical and organizational measures ensure that only authorized persons and systems can access a network. At the same time, data is protected and attacks are detected or averted at an early stage.

Typical measures include firewalls, encryption or access controls.

Where do I come across this issue in my day-to-day work?

• When working in the company network
• When accessing WLAN (in the office or on the move)
• When using cloud services

Practical example:

A company uses a secured WLAN with a password and additional protective measures such as a firewall. Unknown devices cannot simply connect and suspicious activities are blocked.

What can I do to improve my safety?

1. Only use trustworthy networks
2. Do not pass on company accesses
3. Report suspicious connections or warning messages

Remember: A secure network is the basis for protecting all company data.
