Cyberattacks are an evolving danger to organizations, employees, and consumers. These attacks may be designed to access or destroy sensitive data or extort money. They can, in effect, destroy businesses and damage your financial and personal lives — especially if you’re the victim of identity theft. However, a strong cyber security system doesn’t rely solely on cyber defense technology; it also relies on people like you making smart cyber defense choices. The good news is that you don’t need to be a cyber security specialist to understand and practice good cyber defense tactics. This article can help. In this article, you’ll learn about: • cyber security and what it entails • different types of cyber security • three categories of cyber threats • how to recognize, avoid, and defend yourself against cyber threats • Key steps you can take to boost your cyber security • what to consider when choosing a cyber security plan • cyber security FAQs Cyber security is the practice of defending your electronic systems, networks, computers, mobile devices, programs, and data from malicious digital attacks. Cybercriminals can deploy a variety of attacks against individual victims or businesses that can include accessing, changing, or deleting sensitive data; extorting payment; or interfering with business processes. How is cyber security achieved? An umbrella of cyber security can be attained through an infrastructure that’s divided into three key components: IT security, cyber securit...

Cy·ber·se·cur·i·ty. The practice of being protected against the criminal or unauthorized use of electronic data, or the measures taken to achieve this. At least, that’s what the dictionary says. Do you agree? Over the years the term cybersecurity has been thrown around to the point where it is almost synonymous with terms like IT security or information security. It’s kind of like saying every square is a rectangle, but not every rectangle is a square. Confused? Let’s break it down. Cybersecurity Defined Every square IS a rectangle because a square is a quadrilateral with all four angles being right angles. Similarly, cybersecurity IS a part of the IT security umbrella, along with its counterparts, physical security and information security. But not every rectangle is a square, since the criteria to qualify as a square means all sides must be the same length. The point is, not all IT security measures qualify as cybersecurity, as cybersecurity has its own distinct assets to protect. CompTIA’s Chief Technology Evangelist, James Stanger says it best when he Of course, the threat to these electronic assets are hackers who have maliciou...

Tech security: The next challenges Security threats like malware, ransomware and hacking gangs are always evolving. This special report explains what you need to focus on next. Read now Individuals and businesses alike face cybersecurity threats. In addition, businesses need protection from unauthorized data access — both from inside and outside the organization. Strong cybersecurity reduces the chances that a cyberattack will affect business operations. Cybersecurity also has political implications. The US Department of Homeland Security designated election infrastructure as "critical" in 2017. This And cybersecurity can also affect public safety and health. Individuals can take simple steps to maintain their cybersecurity, like using a password manager app. But businesses typically require more sophisticated, proactive cybersecurity strategies. As a result, the number of people responsible for handling a company's cybersecurity depends on an organization's resources and operational needs. A company might have a large cybersecurity team or just one person with multiple digital duties. Is cybersecurity considered an IT job? People who work in cybersecurity often work closely with other IT professionals, like network administrators or in various roles.
