While IT security provides the foundation, cybersecurity adds advanced defences like real-time threat detection. What happens when they are incorporated together in a business strategy?
IT and cybersecurity have a complex and closely connected relationship. Understanding how these two areas work together in a business setting is essential for creating systems that are user-friendly, responsibly automated, scalable, and secure.
Examining the differences between IT and cybersecurity helps to understand their unique roles and how they combine to protect a network.
It can be challenging to distinguish IT from cybersecurity because they share many similarities and have overlapping goals. Both focus on safeguarding sensitive data and information while preventing unauthorised access.
A helpful way to view the relationship is to see cybersecurity as an additional layer built on top of IT security. Using a bank as an example, the main vault represents IT security, while the safety deposit boxes and alarm systems symbolise cybersecurity.
Although the vault, safety deposit boxes, and alarm systems are all designed to provide security, each serves a distinct purpose. The vault serves as the foundation, while the other systems, like cameras and alarms, add extra layers of protection.
This article explores the differences between IT security and cybersecurity, shedding light on their respective roles and why organisations require both to safeguard their operations effectively.
What is IT security?
IT security, or information technology security, focuses on safeguarding both physical and digital data. It encompasses the protection of all forms of information—whether stored in databases, transmitted over networks, or archived in physical formats. The primary objective is to maintain data confidentiality, integrity, and availability, often referred to as the CIA triad.
Key components of IT security include:
- Confidentiality: Ensures that only authorised individuals can access sensitive information.
- Integrity: Guarantees that data remains unaltered except by authorised means.
- Availability: Ensures systems and information are accessible to authorised users when required.
Areas of focus in IT security
- Physical security: Protects physical assets such as servers, hard drives, and documents. Measures may include biometric access controls and surveillance systems.
- Administrative security: Establishes policies and protocols to regulate user behaviour, such as training employees on data protection and confidentiality.
- Technical security: Safeguards data through encryption, firewalls, and intrusion detection systems.
What is cybersecurity?
Cybersecurity is a subset of IT security, specifically addressing threats in the digital space. It focuses on protecting systems, networks, and data from unauthorised access, cyberattacks, and data breaches. Cybersecurity involves strategies and technologies designed to secure electronic data, whether stored on servers, transmitted over the internet, or accessed via devices such as mobile phones and tablets.
Core practices in cybersecurity
- Threat detection and response: Identifies and mitigates potential threats through proactive monitoring.
- Risk assessment: Evaluate vulnerabilities in systems and applications to bolster defences.
- Incident response plans: Prepares organisations to act swiftly in case of cyberattacks, minimising damage and recovery time.
Key differences between IT security and cybersecurity
While IT security and cybersecurity share the goal of protecting sensitive data, they diverge in scope, techniques, and focus. Below are the primary differences:
- Scope of protection
- IT security: Covers both physical and digital assets, addressing the broader spectrum of organisational security. For instance, securing paper files in a locked room falls under IT security.
- Cybersecurity: Concentrates on protecting data in the digital realm, such as information stored on servers or transmitted over networks.
- Techniques implemented
- IT security: Includes creating recovery plans for emergencies, implementing firewalls, and ensuring proper configuration of hardware and networks. It also involves testing security measures before deployment.
- Cybersecurity: Focuses on proactive threat detection and response, such as monitoring networks for suspicious activity, employing encryption tools, and conducting penetration testing to identify vulnerabilities.
- Type of professionals
- IT security: Often managed by IT technicians, chief information officers, and system administrators. These professionals oversee both digital and physical security measures.
- Cybersecurity: Handled by specialised roles such as cybersecurity analysts, engineers, and administrators. Their expertise lies in countering digital threats and securing online systems.
- Format of data
- IT security: Protects both digital and non-digital data formats, such as physical documents and files.
- Cybersecurity: Exclusively deals with electronic data stored or transmitted in cyberspace.
- Cost implications
- IT security: Expenses may include costs for physical security measures, such as monitoring systems and secure storage.
- Cybersecurity: Often requires significant investment in advanced software, tools, and personnel due to the increasing sophistication of cyber threats.
- Operational priority
- IT security: Acts as the foundational layer of defence, ensuring the integrity of all systems.
- Cybersecurity: Operates as an advanced defence mechanism, actively identifying and neutralising threats before they cause harm.
