Two factor authentication, user permissions and firewalls are some of the ways we protect our private information from outside sources. Dr. Dennis Backherms, Southern New Hampshire University (SNHU) adjunct faculty member and academic partner defines information security, as the protection of all information. “That information can be physical, such as a handwritten note, or digital, such as electronic medical records,” he said.

Due to the widespread usage of technology, organizations in need of protection from security threats has been continuously growing. From large global corporations to small startups, anyone using technology to help run their business needs help avoiding security breaches.

If you are interested in working in the information security field, a cyber security degree can be a good place to start.

What is Information Security and Why is it Important?

Information security, more commonly known in the industry as InfoSec, centers around the security triad: confidentiality, integrity and availability (CIA).

These principles, aspects of which you may encounter daily, are outlined in the CIA security model and set the standards for securing data.

  • Confidentiality limits information access to authorized personnel, like having a pin or password to unlock your phone or computer.
  • Integrity ensures information can only be altered by authorized users, safeguarding the information as credible and presenting the organization or site as trustworthy.
  • Availability requires information to be accessible to authorized users any time they need it. To make this possible, systems need to be updated and software backed up.

"Cybersecurity professionals today are concerned more about insider threats and the human factor," said Backherms. "The human factor is considered the weakest link in any InfoSec program."

Due to the human factor, implementing security controls no longer seems to be enough to protect data. Organizations need to now ensure employees are trained properly on top of implementing software/hardware security controls.

Implementing the CIA security model keeps information protected. With growing concerns over privacy and the security of confidential information of both individuals and corporations, companies are putting more resources toward cyber security.

“Most organizations never publish or make their data breaches known. Besides mitigating data loss, brand reputation is usually the number one concern for most large organizations, so we never hear of the most egregious breaches," said Backherms. In fact, larger insurance companies have special policies that cover reputation to help mitigate brand damage should a breach be publicized.

Many organizations have recognized the importance of protecting private information from becoming public, especially when that information is sensitive. The Forbes Technology Council identified some of the top cybersecurity trends to keep an eye out for in 2022.

A few cybersecurity trends include:

  • Ransomware Cyberattacks: Companies may face ransomware attacks where their data and systems are held hostage in return for ransom. This type of cyberattack is believed to grow more this year and in the years to come. According to the Forbes Technology Council, professionals need to be well-positioned and ready to deal with untrustworthy sources.

  • 5G Vulnerabilities: With the new reality of remote work, the cloud and 5G have become necessary for many businesses. While 5G has many advantages, it may lead to more cyberattacks. The high speed that 5G brings to data transfer can allow hackers to go unnoticed, and it’s crucial for companies to implement higher security and roadblocks to access data.

  • Synthetic Identities: This type of fraud occurs when scammers develop a new persona using real and fake data in hopes of financially defrauding someone, taking their money or other assets. For example, companies may need to increase security to confirm job candidate identities to prevent these synthetic identities from coming through.
