Common types of cybersecurity threats

Information can be compromised through a variety of tactics. Examples of common cyberthreats include:^{Footnote 1}

• Malware: Short for “malicious software,” malware variants include worms, viruses, trojans, and spyware. These types of software can give cyberattackers unauthorized access to data or cause damage to a computer system. 

• Ransomware: Ransomware is another type of malware that can lock down computer systems with the threat to destroy or compromise sensitive data unless a ransom is paid to the cyberattacker. 

• Phishing: Phishing is a tactic that attempts to trick users into providing sensitive information, such as their username and password to an account, credit card number, or personal information. This type of scam sends messages from seemingly legitimate organizations asking for the information they intend to steal for their use. 

• Distributed denial-of-service (DDoS) attacks: These types of cyberattacks attempt to crash a server, network, or website by overloading it with traffic. DDoS attacks typically use multiple coordinated systems to achieve the goal of overwhelming the system. 

Online cybersecurity course curriculum

Cybersecurity course curricula will vary based on the type of program, level of learning, and other factors. For example, an introductory course that focuses on cybersecurity fundamentals may cover: 

• Network and system administration basics, such as data integrity, confidentiality, and availability. 

• Protections that cybersecurity professionals use to secure network infrastructures, monitor threats, and implement security solutions. 

• The different branches of cybersecurity, including application security, network and infrastructure security, and digital forensics and incident response. 

Cybersecurity analyst certification courses and cybersecurity boot camps can also provide a more in-depth focus on cybersecurity tools and best practices for aspiring professionals, including how to perform digital forensic analysis, risk analysis, and vulnerability assessments in enterprise environments.

Cybersecurity training for beginners

For those who are interested in exploring cybersecurity careers, it can be helpful to take an introductory class to see if cybersecurity is a good fit. There are many low-cost or free cybersecurity courses online that cover cybersecurity fundamentals, how to start a career in cybersecurity, and more. Introductory classes may cover different areas of cybersecurity, such as secure software development, network security, and cloud security. These courses provide an overview on important cybersecurity terms, how security design works, industry standards and principles, and different models for security.
