What is IT-Security compared to Information Security or Cybersecurity? How can IT-Security help to protect your company? To know the types of security organizations helps you to increase your security and focusing on the right topic to efficiently raise your security level and reducing risk for your business.

1. Definition

IT Security is one part of an overall security organization next to Information Security (What is Information Security?) and Cyber Security. Often the term IT-Security is used as synonym to describe all IT related security topics. Because of that you see a lot of different descriptions and definitions. But you have to understand the real differences between all the types of security organizations to effectively protect your IT infrastrucutre and information assets.

In reality IT-Security has the task to technically protect your IT infrastructure and Information Systems (e.g. network, servers, applications, workstations) to preserve your data against unauthorized access, use, modification, transfer and disclosure. And additionaly to ensure the availability of the IT Systems and information.

2. What are the goals of IT-Security?

In short, the main goal of the IT-Security is to technically protect your data and information by securing your IT Systems. With the implementation of security measures, IT-Security supports the Information Security in the fullfillment of defined protection goals.

In praxis (especially in small/medium sized businesses) you can often find that the IT-Security also takes over tasks/goals that are related to Information Security (see What is Information Security?). However, these remain two seperate topics (same for Cyber Security).

3. How does IT-Security help to protect my data and infrastructure?

In the best case, IT-Security takes over the specifications and requirements defined by the Information Security. Therefor policies and procedures should be in place first.

The IT-Security then takes technical measures by implementing and operating security infrastructure (e.g. Firewalls, Application Gateways, Proxies) and security applications (e.g. Anti-Malware Software, Vulnerability Scanner, Patchmanagement). The goal is to protect your IT Systems, infrastructure and data (assets) against the loss of confidentiality, integrity and availability. The setted up infrastructure not only helps to protect your assets, but also to monitor your environment to detect cyber attacks, cyber threats data breaches or data theft.

You can find of course many specialized teams that are dealing with IT-Security, for example:

  • Network Security
  • Server Security
  • Data Center Security
  • Applicaton Security
  • Production or Industrial Control Systems (ICS) Security

4. Conclusion

This post explained what IT Security is and how it helps to protect your company’s assets.

The best way to describe IT Security is, that it is a “Man in the middle” between, and a supporter for the Information Security and Cyber Security. It is the glue, InfoSec and Cyber Security depends upon, because it not only implements the measures and best practices that come from these both sides. It also helps deliver the necessary key figures and information to evaluate the current security level and risk. Additionally it supports the cybersecurity organization help finding, containing and erradicating security breaches, attacks, threats, etc. by providing the right information (e.g. logs).
