Information security and cybersecurity are two terms that are often used interchangeably, even by professionals who work in the industry. Yet, there are significant differences between information security vs cybersecurity. Although there is some overlap, the two terms refer to different concepts.
One thing they share in common is that both are becoming increasingly more important in today’s modernized world. If you’re thinking of pursuing a high-demand career in the technology industry, a cybersecurity degree or technology degree would prepare you to fight the new generation of black hat hackers. Organizations in all sectors and industries hire cybersecurity professionals to safeguard their systems and protect their customers.
Information Security vs Cybersecurity: An Overview
The primary difference between information security vs cybersecurity is the role of technology. Cybersecurity involves the safety of computer systems and everything contained within them, which includes digital data. In contrast, information security refers to the safety of information in all its forms, whether it’s stored on a computer system or not.
Governments around the world go to great lengths to conceal confidential information from spies of foreign nations. Likewise, corporate espionage is of great concern to major companies. Information security is also significant for individuals. It’s why people are advised to shred their paper tax returns and other sensitive documents before discarding them.
Whereas information security refers to the safety of information contained within or on any medium, cybersecurity is solely concerned with the safety of technology. If you think of information security as an umbrella category, you’ll find cybersecurity nestled within it as a subcategory.
Yet, cybersecurity encompasses more than just the safety of data. Although it’s true that hackers often attempt to gain unauthorized access to a network for the sake of exploiting sensitive data for financial gain, some may disrupt a computer network for other reasons, such as to commit a political attack or act of terrorism. It’s the job of cybersecurity professionals to prevent all types of cyberattacks, and to investigate them when they do occur.
Taking a Closer Look at Information Security
When considering the concept of information security, it can be helpful to think about how it affects your own life. The items you possess that contain sensitive information typically include the following:
- Social Security card
- Birth certificate
- Tax returns
- Credit card statements
- Medical records
Some of these are actual paper documents (e.g. your birth certificate). Others may exist in both paper and digital formats (e.g. your tax returns and credit card statements). In order to effectively protect your sensitive information, you need to prevent unauthorized access to all the available formats it takes—both paper and digital.
The commonly accepted definition of information security acknowledges that it includes three main elements known by their acronym: CIA.
- Confidentiality: Confidential information must be protected from unauthorized access. It’s important to consider that unauthorized access may not always be intentional, but could instead be accidental. For example, someone might accidentally publish confidential information on public websites or leave sensitive data exposed on a publicly viewable computer screen or notepad.
- Integrity: Sensitive information must be protected from improper destruction or modification. In other words, it’s necessary to ensure that data is authentic and accurate.
- Availability: Although it’s important to safeguard information, it cannot be so thoroughly locked away that authorized users cannot access it. The information must remain reliably available to authorized users whenever they need access to it.
Exploring the Fundamentals of Cybersecurity
Cybersecurity refers to the process of protecting all of cyberspace from unauthorized access. It encompasses the protection of servers, online accounts, computer networks and individual computers, as well as other devices, such as mobile phones.
Cybersecurity also extends to smart gadgets, also known as the Internet of Things (IoT). These days, a wide range of devices can connect to the internet, ranging from smart TVs to home surveillance systems to smart window shades and even internet-enabled fish tanks. It’s important for cybersecurity professionals to safeguard all these devices. Hackers can gain unauthorized access to connected devices and then use that access as a stepping stone to gain entry to networks with sensitive data.
Many black hat hackers primarily target sensitive information that they can exploit for financial gain, such as credit card information. They may find this information on a range of networks, from computer systems used for retail stores to those used by hospitals. However, not all hackers are primarily motivated by financial gain.
Some hackers seek to breach the security of computer networks for other purposes. For instance, they may try to access machines to influence or compromise the integrity of the data contained within those machines.
In other cases, hackers may be motivated to commit acts of domestic or international terrorism. For example, a state-sponsored cyberattack may seek to disrupt a country’s infrastructure or to obtain the blueprints for secret military technology.
In order to safeguard the integrity of computer networks and devices:
- Use and regularly update computer programs, including firewalls, to improve the protection of a computer network and its devices
- Carry out penetration testing to detect potential vulnerabilities in the network
- Develop security patches for possible vulnerabilities to prevent hackers from exploiting them
- Monitor computer networks and look for signs of a potential security breach
- Respond quickly to security breaches, cutting off unauthorized access and investigating the breach to determine which data were compromised and whether other parts of the system were adversely affected
- Compile security information into reports and recommendations to be passed along to senior management personnel
Cybersecurity professionals may also work with non-tech employees of their organization. They may help these individuals become more proficient with the use of cybersecurity safeguards.
Should You Earn an Information Technology Degree or a Cybersecurity Degree?
Now that you know the differences between information security vs cybersecurity, you may be thinking of pursuing a career that is dedicated to safeguarding technology for companies and individuals. It can be difficult for students to know exactly which type of degree they should earn, as an information technology degree and a cybersecurity degree are quite similar. However, there are some differences to be aware of.
A Bachelor of Science in Information Technology degree will give you a broad set of skills, such as network administration, database administration, software development and web design. It will also touch on topics pertaining to cybersecurity and information security in general.
In contrast, a Bachelor of Science in Cybersecurity takes a narrower focus. You’ll take a deep dive into specialized topics, such as risk assessment, incident analysis and digital forensic investigations. Since it’s helpful to have both an in-depth and broad skill set, which degree should you choose?
If you have the option to do so, it may be best to select a Bachelor of Science in Information Technology with an Emphasis in Cybersecurity degree. This will give you the best of both worlds—a broad focus on IT in general combined with a close look at cybersecurity.
As cybersecurity becomes increasingly important in a modernized world, those holding a cybersecurity degree may compete for top technology job opportunities. You can become a cybersecurity specialist when you graduate with a Bachelor of Science in Information Technology with an Emphasis in Cybersecurity degree from Grand Canyon University. Emerge with a solid foundation of knowledge in key areas including digital forensic investigations, security architecture and secure system administration.
