Information Security Vs Cyber Security: How Are They Mutually Exclusive?

Information Security and Cyber Security are two separate fields, but with way too much overlap there to create confusion in understanding the concepts of each. This post takes a deep dive into an overview of information security vs cyber security so that you can make an informed decision regarding your knowledge and levels of protection for your private or public sector organization.

Key Takeaways

Information security focuses on protecting data from unauthorized access and ensuring its confidentiality, integrity, and availability.
Cyber security specifically targets the protection of networks, systems, and data from cyber threats and attacks.
Both information security and cyber security play crucial roles in safeguarding sensitive information and preventing data breaches.
The two fields overlap but serve distinct purposes, with cyber security dealing primarily with external threats and information security addressing both internal and external risks.
Implementing comprehensive security protocols, such as encryption and access controls, is essential for protecting organizational data effectively.

What is Information Security?

Information Security (also known as InfoSec) is the process of protecting information assets from unauthorized access, use, modification, disclosure, and destruction. It encompasses all facets of protecting the confidentiality, integrity, and availability of the information.

The purpose of information security is to help organizations protect their intellectual property, customer data, trade secrets, data within a CRM, proprietary information, and other assets–such as resources of value–from being accessed, used, or disclosed by unauthorized parties with malicious intent.

In today’s tech-driven world, where people are constantly sharing information online via email, social media accounts, and more, companies must implement strong information security programs so that they can protect their data and prevent it from being hacked. Therefore, mitigating the risk of losing customers and brand integrity.

Information security can be achieved through the use of security measures like encryption keys, access control policy and email authentication.

For example, a company may have an online store that sells its products, but it needs to protect the data that identifies customers and their orders. The company’s information security measures include encrypting all of its transmitted information, developing and enforcing policies around password use and file sharing, and monitoring all access to network resources.

What is Cyber Security?

Cyber Security is the process of protecting networks, systems, and data from unauthorized access, modification, and destruction. It is an umbrella term for a group of related technologies and disciplines that help to prevent unauthorized access to networks, systems, and data.

Cybersecurity can be broken down into three main categories; risk analysis, detection and response, and protection.

Risk analysis involves identifying potential risks to your organization’s networks and systems so you can prioritize where to spend your cybersecurity budget.
Detection involves monitoring activity on your network to detect any unauthorized activity or activity that might indicate a breach has occurred.
Protection involves protecting your information systems from being attacked by hackers using various methods such as firewalls and intrusion detection systems (IDSs).

For organizations to be successful in an increasingly digital world, they must ensure that their cyber security practices are robust enough to prevent, identify, and respond to cyber threats to maintain the security of data and networks.

Cyber security can also help prevent corporate espionage in other ways. For example, if someone inside your company tries to access another employee’s account on your network, they will be blocked by the firewall until they have been authenticated and authorized by the proper authorities.

Information Security vs Cyber Security: The Differences

Information security and cyber security are two distinct fields of information technology that complement each other.

These two disciplines often overlap in their practice as technologies evolve but each should be given consideration individually for its purpose or applications.

Let’s read how they differ from one another in the Information Security vs Cyber Security comparison shared below:

Protection Parameters

Cyber security protects cyberspace from threats, while information security is the protection of overall data from threats.

Cyber security focuses on the protection of networks, devices, and systems against cyber attacks. It also aims to protect individuals against identity theft, fraud, and other online crimes. Cyber security is concerned with protecting users’ privacy through encryption in their communications and data. This means that cyber security does not protect companies’ intellectual property or provide for employee privacy.

Information security focuses on protecting organizations’ data from unauthorized access by employees or outsiders. It is concerned with ensuring that confidential information is stored securely without falling into the hands of third parties who could use it inappropriately or even cause harm to its owner. Information security can be divided into three categories: physical (e.g., locking away documents), logical (e.g., encrypting sensitive data), and administrative controls (e.g., changing passwords periodically).

A good way to think about these two approaches is to consider how they relate to each other in terms of risks. Cybersecurity focuses on risk management and controls that are used to prevent harm from occurring within cyberspace; whereas information security focuses on risk management and controls for managing threats to individual systems (or organizations).

Security Scope

Cyber security is the process of protecting information in cyberspace. It deals with protecting the data or information that resides in a computer system or network from being compromised by hackers, viruses, and other malicious software. Since cybercrime is a global threat, businesses often choose cyber security localization to strengthen the security of their web properties.

Information security on the other hand is the broader umbrella term that includes all of the techniques used to protect information from unauthorized access, use, disclosure, modification, or destruction in any form. It protects data and information regardless of whether they are stored on a hard drive in an office building, or on an external server in another country.

The key takeaway here is that Cyber Security provides defense mechanisms within the cyber realm only while Information Security looks at protecting data regardless of where it resides or how it is used (i.e., at home or in business).

Threat Shielding

Cybersecurity is concerned with the protection of computer networks and technologies from cyberattacks, cyberterrorism, and other kinds of attacks that use computers or networks as their means. On the other hand, information security focuses on protecting data in whatever format it’s stored.

For example, if you’re trying to protect your email messages from being stolen by hackers, you’re dealing with cybersecurity. If you’re trying to protect your family’s health records from getting into the wrong hands, you’re dealing with information security.

Therefore…

Cybersecurity deals with those threats in cyberspace—those that occur when you’re using your computer or mobile device, or even when you’re connected to the Internet. Information security deals with any form of threat related to the protection of any sort of data—whether it’s physical data like financial records or other types of information like email accounts.

Combat Approach

Cybersecurity refers to the technology that protects information systems from cyber-attacks. Information security refers to the techniques that companies use to protect their data and systems from unauthorized access, disclosure of confidential information, or disruption by hackers.

➜ Cybersecurity combats:

Cybercrime – a broad term that describes any illegal activity that happens online. Some cybercrimes include hacking, phishing, identity theft, and other crimes.

Cyber fraud – a digital scam committed through the internet or email, e.g credit card fraud (where someone steals your credit card information and uses it to make purchases online.)

➜ Information security combats:

Unauthorized access – when a person or entity accesses information without authorization. An example of unauthorized access is someone who steals data on a server or network.

Disclosure modification – when an attacker intentionally modifies the data in such a way that it can be used against the original owner.

Disruption – the act of interfering with normal operations of a system to deny service to legitimate users, causing outages and delays in orders being fulfilled.

Therefore, the difference between information security and cyber security is like the difference between guarding a castle with a sword versus using a gun to defend it—both are necessary for keeping your castle safe, but one is more effective than the other depending on your circumstances. This makes both of them an important aspect of any organization’s overall protection strategy.

Defense Activation

Cybersecurity is the first line of defense against cyber threats. It’s what we call “the good guys” when they’re trying to prevent hackers from infiltrating your computer or stealing your personal information.

Information security is what happens when cyber security fails—when it is breached and malicious code gets past the firewall and into your system. Information security helps you prevent breaches and recover quickly from them so that you can continue to use your system without interruption.

Because cyber security deals with external threats, it’s often referred to as “outside-in” protection, while information security is more of an “inside-out” approach that focuses on both internal and external risks.

Information Security vs Cyber Security: The Overlaps

Information security and cybersecurity are two separate, but related, fields. It’s because they both focus on protecting the confidentiality, integrity, and availability of sensitive information from unauthorized access or use.

There are some key overlapping concerns in this space:

both fields look at threats to data security that might come from any source (including human error)
both fields look at protecting data as it flows through networks or devices
both fields look at securing devices so that they’re not vulnerable to attack by hackers or other bad actors

To sum it up, information security provides the technological components needed to protect data while cyber-security provides a framework for how those technical components should be used by organizations that want their data protected from attackers.

Email Security as a Part of Information Security

A proper information security framework also incorporates email security since most information in a corporate setup is exchanged via emails.
