Cybersecurity vs. Information Security vs. Network Security

Everyone knows that security is essential in the Digital Age. Regular news reports about high-profile avg.com/retail   cyberattacks and data breaches avg internet security leave no doubt www.avg.com/activate that strong security is a must. But what’s the difference between avg antivirus free information security, cybersecurity and network security.

There is definitely some confusion avg internet security around these terms, in part because there’s a significant amount of overlap between them Install Avg With License Number activation.

In one sense, information security dates back to when humans began keeping secrets; in the early days, physical files and documents were kept under literal lock and key. Once the business world began using avg internet security computers,

 

network security became essential to protect the electronic network infrastructure of these www.avg.com/activate vital systems. The advent of the internet changed everything avg antivirus free, adding once-unimagined technological capabilities but also creating new vulnerabilities; and giving rise to a critical avg.com/retail   new industry — cybersecurity.

So, which is the most important? While the first two are certainly critical to the practice of keeping systems, information and assets secure, it is cybersecurity that generates the lion’s share of the avg antivirus free discussion these days.

Nevertheless, some analyses regard information security as the umbrella term because it refers to the processes and techniques avg.com/retail   designed to protect any kind of sensitive data and information Install Avg With License Number activation from avg internet security unauthorized access, whether in print or electronic form.

Under this view, cybersecurity is a subset of information security that deals with protecting an organization’s internet-connected systems from potential cyberattacks; and network security is a subset of cybersecurity that is focused on protecting an organization’s IT infrastructure from avg antivirus free online threats. Though the terms are often used www.avg.com/activate in conjunction with one another, cybersecurity is considered to be the broader discipline, with network security defined as one aspect of information and/or cybersecurity.

How do some of the industry’s leading players define these essential and closely related security terms?

Information security, according to security training specialist the Snans instiitute refers to the processes and methodologies Install Avg With License Number activation which are designed and implemented to protect print, electronic, or any other form avg internet security of confidential, private and sensitive information or data from avg.com/retail   unauthorized access avg antivirus free, use, misuse, disclosure, destruction, modification, or disruption.” The reference to “print” and information or data is significant, since cybersecurity pertains solely to digital or electronic information or data.

 Cybersecurity is “the practice of protecting systems, networks and programs from digital attacks,” according to high-tech giant Cisco “These attacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes PC mag simplifies the definition to: “the protection of data and systems in networks that are connected to the internet.”

Network security, the sans institute explains, is “the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorized access www.avg.com/activate, misuse avg antivirus free, malfunction, modification, destruction, or improper disclosure avg.com/retail   avg internet security, thereby creating a secure platform Install Avg With License Number activation for computers, users and programs to perform their permitted critical functions within a secure environment.”

Whenever the conversation turns to information security, network security and cybersecurity, it is helpful to understand the CIA triad. Though the term CIA might at first bring to mind a shadowy world of spies and secrets when used in connection with the clandestine security industry, in this context it actually refers to a series of guidelines and objectives that security experts avg antivirus free are focused on when developing policies and procedures avg internet security for an effective information security program. The three elements of theCIA triad are considered the three most crucial components of information security.

CIA – Confidentiality, Integrity, Availability

Confidentiality: Ensuring that the information is inaccessible to unauthorized people, commonly enforced through encryption avg.com/retail  , IDs and passwords, two-factor authentication and additional avg.com/retail   defensive strategies.

Integrity: Safeguarding information www.avg.com/activate     and systems from being modified by unauthorized people, thereby ensuring that avg.com/retail   the protected avg internet security data avg antivirus free is accurate and trustworthy.

Availability: Ensuring that authorized people have access to the information when needed; this includes rigorously maintaining Install Avg With License Number activation all systems, keeping them current with upgrades, using backups to safeguard against disruptions or data loss, etc.
