Cyber Challenges

Cybersecurity or information technology security (IT security) is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

Top cybersecurity challenges include evolving ransomware, AI-powered attacks, advanced social engineering, and securing multi-cloud environments. The increasing use of AI by both attackers and defenders is rapidly shaping the threat landscape, while the expansion of remote work has broadened the attack surface for vulnerabilities in areas like IoT devices and supply chains.

Cyber Teams

The cybersecurity color wheel categorizes cyber teams by their roles:

  • Red Team are ethical hackers,
  • Blue Team are defenders,
  • Yellow Team are developers who build secure applications.
  • Purple Team facilitates collaboration between Red and Blue
  • Green Team works with Yellow and Blue to implement secure coding practices
  • Orange Team trains Yellow developers
  • White Team manages the overall strategy, compliance, and coordination.

Cyber Tools

This is a list of cybersecurity information technologies. Cybersecurity concerns all technologies that store, manipulate, or move computer data, such as computers, data networks, and all devices connected to or included in said networks, such as routers and switches. All information technology devices and facilities need to be secured against intrusion, unauthorized use, and vandalism. Users of information technology are to be protected from theft of assets, extortion, identity theft, loss of privacy, damage to equipment, business process compromise, and general disruption. The public should be protected against acts of cyberterrorism, such as compromise or denial of service.

Cybersecurity is a major endeavor in the IT industry. There are a number of professional certifications given for cybersecurity training and expertise.[1] Billions of dollars are spent annually on cybersecurity, but no computer or network is immune from attacks or can be considered completely secure.

Cyber Competitions Overview

The most important cybersecurity competitions fall into different categories, from prestigious Capture the Flag (CTF) events for skilled hackers to defensive competitions for students and challenges focused on specific, high-stakes exploits. The significance of a competition can vary depending on one’s career level and goals, whether it’s for learning, recruiting, or showcasing elite skills. There are also other competitions such as those on the Kaggle website and by Leet code (see weblinks for urls).

  • For top professionals and ethical hackers
  • For university students
  • For high school and younger students
  • General and online competitions
