A Brief Look at Information Security.

 Based in Greater Boston, Wayne Nordstrom worked as a lead network engineer at Suffolk University, where he was in charge of the campus' wide network infrastructure. In addition, Wayne Nordstrom earned his BS in cybersecurity and digital forensics at Champlain College, which the nation recognizes as a leading force in those fields of study.

As a discipline, cybersecurity deals with the procedures involved in safeguarding systems, networks, and sensitive information from digital attacks. And some of these attacks include phishing, malware, spyware, zero-day exploits, and man-in-the-middle. In addition, cybersecurity has vital components, including network security, operational security, disaster recovery planning, and information security.

Also known as infosec, information security refers to the techniques employed in shielding information from unauthorized access, use, modification, or destruction. The subject matter of this discipline (information) covers a person's intellectual property, personal details, login details, and social media profile, among other aspects. Information security consists of three fundamental principles; confidentiality, integrity, and availability (CIA triad).

Confidentiality means protecting sensitive information, which the owner restricts to a few people. This includes professional information, bank account details, social media profile, family information, and email details, to mention a few. On the other hand, integrity means keeping the accuracy and entirety of any information intact.

Finally, availability helps the owners of specific pieces of information in accessing them whenever they desire. However, attackers can attempt to carry out a denial of service (DoS) attack to take down a web server if they fail to jeopardize the confidentiality and integrity principles. As a result of the attack, an authorized website owner can lose access to their site due to unavailability.
