IT security

Even though the two terms are often used interchangeably in colloquial language, they cover different aspects of technological security.

What is IT security?

This is a sub-field of information security. It focuses on electronically stored information and IT systems. It specifically refers to protection against threats such as hacker attacks, unauthorised data access or espionage. There are various solutions for creating this security. From firewalls and anti-virus programmes to backups, all of these are used here. IT security is broadly diversified and covers protection against both internal and external threats. These can be the following things:

  • Physical security: This refers to the protection of hardware and other physical systems
  • Technical safety: The focus here is on securing data that is stored and transmitted within a network.
  • Administrative security: This refers to the implementation of guidelines and processes for user control in the network, but also the development of

What is cybersecurity?

With the Cybersecurity the focus is extended to IT security and relates to all networks and the entire Internet. In the case of networks, all connected systems and data are secured, including critical infrastructures such as telecommunications and the power supply. Cybersecurity is therefore not limited to individual companies but focuses on the entirety of the networked digital world.

This is particularly concerned with threats from cyberspace. Cybercrime, attacks and fraud are covered here. The tasks here are as follows:

  • The protection of electronic communication
  • The prevention and restoration of damage that has occurred to digital systems
  • The focus on online data and its security

What are the differences and overlaps between the two systems?

It can be said that the biggest difference between the two systems lies in the scope and focus of the areas of application. The IT security takes a more holistic approach here, focussing on physical and digital information, while cybersecurity is certainly more concerned with digital threats from the internet. The overlap is that both areas represent a partial aspect of information security. 

It is important that IT experts have a deep understanding of both approaches so that they can develop effective security strategies. This is where a targeted risk assessment can take place and then specific protective measures can be implemented for physical and digital systems.

The differences are an important differentiation. Each of the two fields has its own specific challenges that require appropriate expertise and approaches in order to optimally protect the networked and digitalised world. It is therefore important that every organisation trains employees in the different security practices. Regular risk assessments, which take place after security audits, are absolutely vital for organisations. This is followed by planning which advanced security technologies will be used in the respective company.
