What is the difference between network security, information security and computer security?

Answer 1

NETWORK SECURITY:

Network security, a subset of cybersecurity, aims to protect any data that is being sent through devices in your network to ensure that the information is not changed or intercepted. The role of network security is to protect the organization’s IT infrastructure from all types of cyber threats:

1. Viruses, worms and Trojan horses
2. Zero-day attacks
3. Hacker attacks

INFORMATION SECURITY:

Information security ensures that both physical and digital data is protected from unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction. When InfoSec experts are developing policies and procedures for an effective information security program, they use the CIA (confidentiality, integrity and availability) triad as a guide. The components of the CIA triad are:

1. Confidentiality: ensures information is inaccessible to unauthorized people—most commonly enforced through encryption—which is available in many forms
2. Integrity: protects information and systems from being modified by unauthorized people; ensures the data is accurate and trustworthy
3. Availability: ensures authorized people can access the information when needed and that all hardware and software are maintained properly and updated when necessary

COMPUTER SECURITY:

Computer security, a subset of information security, is the practice of defending your organization’s networks, computers and data from unauthorized digital access, attack or damage by implementing various processes, technologies and practices. With the countless sophisticated threat actors targeting all types of organizations, it is critical that your IT infrastructure is secured at all times to prevent a full-scale attack on your network and risk exposing your company’ data and reputation.
