what is IT security

About IT Security

IT security, at its core, refers to the practice of safeguarding computer systems, networks, and data from theft, damage, or unauthorized access.

As we increasingly rely on digital solutions for everything from communication and entertainment to banking and healthcare, the importance of protecting our digital footprint becomes paramount.

Think of IT Security as the digital equivalent of locking your doors at night or setting up a security system for your home. Just as you wouldn’t want strangers accessing your personal belongings, in the digital realm, we strive to keep sensitive information—like personal details or financial data—safe from cybercriminals and malicious software.

As technology evolves, so do the methods of those looking to exploit it, making IT Security an ever-evolving field that is in high demand in today’s interconnected world.

the difference between cloud security and network security

Cloud vs Network Security

IT Security is an over-arching term that refers to protecting digital assets: 

  • on the cloud
  • in a network environment
  • and the convergence of the two

At its core, both cloud and network security aim to protect digital assets, but they focus on different environments and attack vectors.

Network security deals with safeguarding the integrity, confidentiality, and availability of data as it is transmitted across or accessed from networks.

This includes measures to guard against unauthorized intrusions, malware, and other potential threats that could exploit vulnerabilities in a network’s infrastructure.

Techniques like firewalls, intrusion detection systems, and Virtual Private Networks (VPNs) are typical elements of network security.

Cloud security specifically addresses the challenges of protecting data, applications, and services hosted in cloud environments.

This includes not only the security measures the cloud provider implements, but also the policies, procedures, and technologies that customers put in place to ensure their data remains safe within the cloud.

Cloud security often involves areas like secure access control, encryption, and threat detection.

So, while there is overlap between network and cloud security, network security primarily concerns digital security on a network infrastructure and cloud security primarily protects digital assets on cloud-based resources.

What Does the Term Cybersecurity Mean?

IT security and cybersecurity are related terms that people can find confusing, as they often overlap, but they have slightly different focuses within the realm of protecting information systems and data.

IT security includes a wide range of practices, policies, and technologies that aim to safeguard data and resources within an organization’s IT infrastructure. 

This can involve physical security measures, network security, access control, data encryption, and more. IT security is concerned with protecting not only digital assets but also physical assets that may have an impact on the overall security of an organization’s operations.

Cybersecurity is a subset of IT security that specifically focuses on protecting digital information and systems from cyber threats.

Cybersecurity involves measures and strategies aimed at safeguarding computer systems, networks, and data from threats. It often includes technologies such as firewalls, intrusion detection systems, antivirus software, and security protocols designed to prevent, detect, and respond to cyberattacks.
