It can be difficult for businesses to fully secure their networks. Physical and digital systems need to be managed. Malicious actors continually scan networks in hopes of stealing data. Even software additions need to be secured as every new integration is an entry point for hackers. Threats like these are why a proactive approach to network security is necessary, and IT Security and Cybersecurity both address these concerns in different ways. This article will discuss these differences and explain how these approaches to network security support a sustainable business.
Why Businesses Need Network Security
Businesses depend on physical hardware (like servers and routers) and digital systems (like software and cloud services) to operate. A weak point in one can put the other at risk. For example, a small misconfiguration in a server rack can expose a network to unauthorized access. Likewise, a compromised application update can serve as a gateway for hackers into larger systems. The idea with network security is to minimize these risks.
What Is Information Technology Security?
IT Security covers the protection and operation of the physical and digital components of a network. It’s designed to protect data and may include policies around safe physical server access, backing up systems, disaster recovery, and the protection of infrastructure elements. Common security methods used in IT Security include:
- Encryption
- Access controls
- Authentifications
- Network security protocols
- Endpoint security, and more
This is to protect assets from threats like cyber attacks and data breaches and may include enforcing access control protocols, updating software, and handling disaster recovery.
What Is Cybersecurity?
Cybersecurity is a subset of IT Security, focused on protecting digital data and systems from cyber threats. It zeroes in on preventing, detecting, and responding to threats that come up in the digital space (like hackers). With cybersecurity, there are multiple layers of protection available to prevent loss or data theft. One for example being firewalls. Some of the more common cyber risks businesses face include:
- Malware, malicious software that infects systems with viruses, worms, etc.
- Ransomware, encrypting files then demanding payment for the decryption key
- Phishing, social engineering attacks to trick users into providing credentials or installing malware
- Distributed denial of service (DDoS) attacks, overwhelming systems with traffic, causing server shutdowns
Cybersecurity specialists will complete penetration testing (ethical hacking) which focuses on addressing defenses against the risks above. This is to develop more appropriate strategies to defend against cyberattacks and identify vulnerabilities in the system. Ultimately, both IT and Cybersecurity work to protect the confidentiality, integrity, and availability of data, also known as the CIA Triad.
Building A Secure Network Infrastructure
An effective network security strategy must guard both the physical and digital parts of your
business. This is how you build a resilient infrastructure and support sustainability.
