What are the different types of cybersecurity threats?

The process of keeping up with new technologies, types of Cyber security threats and threat intelligence is a challenging task. It is necessary in order to protect information and other assets from cyber threats, which take many forms, more will be discussed in full details in other lessons. Types of cyber threats include:

  • Malware is a form of malicious software in which any file or program can be used to harm a computer user. This includes worms, viruses, Trojans and spyware.
  • Ransomware is another type of malware. It involves an attacker locking the victim’s computer system files — typically through encryption — and demanding a payment to decrypt and unlock them.
  • Social engineering is an attack that relies on human interaction to trick users into breaking security procedures to gain sensitive information that is typically protected.
  • Phishing is a form of social engineering where fraudulent email or text messages that resemble those from reputable or known sources are sent. Often random attacks, the intent of these messages is to steal sensitive data, such as credit card or login information.
  • Spear phishing is a type of phishing attack that has an intended target user, organization or business.
  • Insider threats are security breaches or losses caused by humans — for example, employees, contractors or customers. Insider threats can be malicious or negligent in nature.
  • Distributed denial-of-service (DDoS) attacks are those in which multiple systems disrupt the traffic of a targeted system, such as a server, website or other network resource. By flooding the target with messages, connection requests or packets, the attackers can slow the system or crash it, preventing legitimate traffic from using it.
  • Advanced persistent threats (APTs) are prolonged targeted attacks in which an attacker infiltrates a network and remains undetected for long periods of time with the aim to steal data.
  • Man-in-the-middle (MitM) attacks are eavesdropping attacks that involve an attacker intercepting and relaying messages between two parties who believe they are communicating with each other.

Other types of Cyber security threats, drive-by-download attacks, exploit kits, malvertising, vishing, credential stuffing attacks, cross-site scripting (XSS) attacks, SQL injection attacks, business email compromise (BEC) and zero-day exploits.

What are the top types of Cyber security threats?

Cyber security is continually challenged by hackers, data loss, privacy, risk management and changing cyber security strategies. The number of cyber attacks is not expected to decrease in the near future. Moreover, increased entry points for attacks, such as with the arrival of the internet of things (IoT), increase the need to secure networks and devices.

One of the most problematic elements of cyber security is the evolving nature of security risks and types of Cyber security threats. As new technologies emerge, and as technology is used in new or different ways, new attack avenues are developed. Keeping up with these frequent changes and advances in attacks, as well as updating practices to protect against them, can be challenging. Issues include ensuring all elements of cyber security are continually updated to protect against potential vulnerabilities. This can be especially difficult for smaller organizations without the staff or in-house resources.

Additionally, organizations can gather a lot of potential data on individuals who use one or more of their services. With more data being collected, the likelihood of a cybercriminal who wants to steal personally identifiable information (PII) is another concern. For example, an organization that stores PII in the cloud may be subject to a ransomware attack. Organizations should do what they can to prevent a cloud breach.

Cyber security programs should also address end-user education, as employees may accidently bring viruses into the workplace on their laptops or mobile devices. Regular security awareness training will help employees do their part in keeping their company safe from types of Cyber security threats.

Another challenge to cyber security includes a shortage of qualified cyber security personnel. As the amount of data collected and used by businesses grows, the need for cyber security staff to analyze, manage and respond to incidents also increases. (ISC)2 estimated the workplace gap between needed cyber security jobs and security professionals at 3.1 million.

Cybersecurity vendors and tools

Vendors in the cybersecurity field typically offer a variety of security products and services. Common security tools and systems include:

  • Identity and access management (IAM)
  • Firewalls
  • Endpoint protection
  • Antimalware
  • Intrusion prevention/detection systems (IPS/IDS)
  • Data loss prevention (DLP)
  • Endpoint detection and response
  • Security information and event management (SIEM)
  • Encryption tools
  • Vulnerability scanners
  • Virtual private networks (VPNs)
  • Cloud workload protection platform (CWPP)
  • Cloud access security broker (CASB)
