Introduction to cyber security

What is cybersecurity all about? A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defense from cyber attacks. A People Users must understand and comply with basic data security principles like choosing strong passwords, being wary of attachments in email, and backing up data. Learn more about basic cybersecurity principles with these Technology Technology is essential to giving organizations and individuals the computer security tools needed to protect themselves from cyber attacks. Three main entities must be protected: endpoint devices like computers, smart devices, and routers; networks; and the cloud. Common technology used to protect these entities include next-generation firewalls, DNS filtering, malware protection, antivirus software, and email security solutions. Why is cybersecurity important? In today’s connected world, everyone benefits from advanced cyberdefense programs. At an individual level, a cybersecurity attack can result in everything from identity theft, to extortion attempts, to the loss of important data like family photos. Everyone relies on critical infrastructure like power plants, hospitals, and financial service companies. Securing these and other organizations is essential to keeping our society functioning. Everyone also bene...

On the Internet, information is widespread—and business operators, alike, risk data theft. Every year, technology becomes more complicated—and so do cyber attacks. The world of digital crime is expansive—and it isn’t exclusive to any particular Internet-accessible platform. Desktops, smartphones, and tablets may each carry a degree of digital defense—but each has inherent ‘weak points’ to which hackers have become attuned. Fortunately, some digital security tools and services run parallel to their ill-intended tech counterparts. Even though our digital landscape’s complexity obscures advanced threats, most can leverage network-based assaults with digital disaster prevention tools. Before we dive into these common threats, let’s dive into the cornerstones of digital security. Because today’s digital threats don’t exclusively exist on hardware, so ascertaining risk requires a different approach—one which prioritizes controlled network security over all else. Defining Modern Cybersecurity: Network-Based Safety When the term ‘ The driving factor behind this technicality, then, is a little easier to understand: Most devices—including navigation apps, game apps, and social media, are Cybersecurity jobs, today, handle the digital defense of information sent and received between digital devices; in essence, network defense. It involves information storage protection, the identification of intrusions, the response to cyber attacks, and—in worst-case scenarios—the recovery of valuab...

Cybersecurity involves everyone and every entity — from you and your neighbors to organizations and companies to governments. It’s considered a fundamental necessity, and in this introduction to cybersecurity course, you’ll learn how to protect yourself and others from online attacks. This is a great starting point for anyone interested in learning cybersecurity but not sure where to start. Sarai Fernandez Computer Science Domain Manager at Codecademy Sarai is the Computer Science Domain Manager at Codecademy. Sarai has a B.S. in Symbolic Systems with a Human Computer Interaction Concentration from Stanford University. While much of her technical knowledge comes from the courses she took in college, she learned Python from Codecademy!

Picture an employee at her computer, working with data. In the background, a hacker secretly accesses her company’s confidential files. He steals sensitive information and sells it to criminals, who then hold the company ransom for a profit. It sounds like something out of a movie, but unfortunately, it’s a common occurrence in today’s online landscape. This is why Cyber Security has become such a vital part of any business strategy—and Cyber Security specialists are In this introduction to Looking forward to a career in Cyber Security? Then check out the What is Cyber Security? Cyber Security is a process that’s designed to protect networks and devices from external threats. Businesses typically employ The world of Cyber Security revolves around the industry standard of confidentiality, integrity, and availability, or The main element of Cyber Security is the use of authentication mechanisms. For example, a user name identifies an account that a user wants to access, while a password is a mechanism that proves the user is who he claims to be. Types of Cyber Crimes Cybercriminals usually try to profit off of their crimes using a variety of tactics, including: • Denial of Service, or DOS Where a hacker consumes all of a server’s resources, so there’s nothing for legitimate users to access • Malware Where victims are hit with a worm or virus that renders their devices useless • Man in the Middle Where a hacker puts himself between a victim’s machine and a router to sniff dat...
