What is the difference between cybersecurity and information security system?Can you help me selecting the best?

The terms Cyber Security and Information Security are often used interchangeably. As they both are responsible for the security and protecting the computer system from threats and information breaches. 

Cyber Security is the practice of protecting the data from outside the resource on the internet.    

Information Security is all about protecting information from unauthorised users, access, and data modification or removal in order to provide confidentiality, integrity, and availability.

Cyber security professionals deal with the prevention of active threats or Advanced Persistent threats (APT).

Information security professionals are the foundation of data security and security professionals associated with it are responsible for policies, processes, and organizational roles and responsibilities that assure confidentiality, integrity, and availability.

Over the last decade, we’ve seen a fusion between cybersecurity and information security, as these previously siloed positions have come together. 

The challenge is, most teams don’t have an information security professional on staff—so the responsibilities of a cybersecurity professional have expanded dramatically. Cybersecurity professionals traditionally understand the technology, firewalls, and intrusion protection systems needed, but weren’t necessarily brought up in the data evaluation business.

But today, that is changing.

As this subject becomes increasingly important for businesses, the role of cybersecurity risk management experts is evolving so they can properly protect data. Business partners and investors are increasingly aware of the importance of this topic, and companies are asked regularly about their effectiveness in securing data and managing both physical and cyber risk.
