Definition – Cyber security

Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories:

Network security, Application security, Information security, Operational security, Disaster recovery and business continuity and End-user education.

Here we will only focus on the last one

Definition – Cybersecurity

‘cybersecurity’ is defined in the Cybersecurity Act (Regulation (EU) 2019/881) to cover “the activities necessary to protect network and information systems, the users of such systems, and other persons affected by cyber threats”. A ‘cyber threat’ is a “potential circumstance, event or action that could damage, disrupt or otherwise adversely impact network and information systems, the users of such systems and other persons”;

End-user education


End-user education addresses the most unpredictable cyber-security factor: people. Anyone can accidentally introduce a virus to an otherwise secure system by failing to follow good security practices. Teaching users to delete suspicious email attachments, not plug in unidentified USB drives, and various other important lessons is vital for the security of any organization.

Cyber safety tips – protect yourself against cyberattacks:

  • Update your software and operating system
  • Use anti-virus software
  • Use strong passwords
  • Do not open email attachments from unknown senders
  • Do not click on links in emails from unknown senders or unfamiliar websites
  • Avoid using unsecure Wi-Fi networks in public places

Cyber safety tips – in other words:

Pay attention to every email: Who is the sender and why are you receiving it?

Great questions to ask yourself:

Why should I click on the link in this email?

Why is this email filled with spelling errors?

Why is my boss asking me to transfer money to an unknown account?

If you are unsure whether the email is fake or not, don’t hesitate to call or

write back to the sender – alternatively ask a good colleague for advice.

Cyber safety tips – in other words:

Stop reusing your password across different accounts – you wouldn’t use

the same key for your home, your car and your workplace.

This password is bad: “Laura76” – using your first name and the year you were born is simply way too easy to guess.

This password is great: “IWannaDanceWithSomebody1992” – everyone has lyrics they’ll always remember. Use these unforgettable words and spice them up with numbers and capitals to create a strong password.

Cyber safety tips – in other words:

When online, the best thing you can be is really boring. This means keeping

sensitive information to yourself unless people you trust need it.

3 steps to becoming really boring:

1.Always keep your information safe. Both offline and online.

2.Never provide your account details, civil registration number, or similar information to companies you don’t trust.

3.Destroy outdated information. This applies both to old documents and information stored on your computer.

Cybersecurity is activities to protect against cyber threats. Here there are several areas of weak spots that have to be protected. The last one of the is end-user education. This could be password handling, mail attachments and avoiding suspicious links in general.
