Cybersecurity 101: Adopting A Security Mindset

Define cybersecurity as protecting computer systems and networks from theft, damage, and data disruption, through defensive, offensive, and a mixture of approaches, with examples like supply chain attacks and ransomware.

Explore the CIA triad: confidentiality, integrity, and availability, and see how least privilege, encryption, access controls, and redundancy protect data and services in cybersecurity.

Explore the major areas of cybersecurity, including application security, offensive security (OPSEC), network security, security engineering, and compliance, with emphasis on the CIA triad and various job-related roles.

Explore threat actor types from script kiddies to nation-state hackers, uncover their motives, methods, and resources, including insiders and competitors, and how advanced persistent threats exploit zero-days.

Understand white hat, gray hat, and black hat roles in cybersecurity, with real-world examples like firmware updates on routers, and explore red, blue, and green hats as related threat actors.

Examine red team, blue team, and purple team roles, including legal scope for red team testing, blue-team defense, and purple-team feedback loops to improve collaboration and policy.

Adopt a security mindset by examining malware types, including viruses, crypto malware, ransomware, trojans, and logic bombs, and learn how their differences guide identification and defense.

Discover how CVEs reveal bugs across systems and libraries, and how NIST guides risk management. Consult the National Vulnerability Database and Meeta to monitor severity and apply updates.

Learn about the open web application security project (owasp) and its valuable, open resources for securing web apps, addressing vulnerabilities, and implementing secure docker containers.

Adopting a security mindset by exploring the Kobayashi Maru thought experiment, learning to think like an adversary, and using outside-the-box testing to reveal threats and risks.

Secure ai, ml, and data science models by restricting authorization and authentication, monitoring for anomalies, preparing for errors with redundancies and backups, and guarding input against cross-site scripting and poisoning.

Master the browser inspector to inspect elements, view the console, and read html structure, then use Lighthouse, certificate checks, and security insights to prep for CTF challenges.

Explore capture the flag challenges in cybersecurity, where teams find flags and earn points by solving exploits. Practice on platforms like HackerOne and CTFtime to reinforce cybersecurity skills through competition.

Deploy the juice shop insecure web app on Heroku and explore the top 10 vulnerabilities as you prepare to test a cross-site scripting attack and locate the dashboard in ctf.

Explore XSS vulnerabilities and how attackers inject malicious code into websites that display unsanitized user input, threatening data confidentiality and integrity, with sanitisation and prevention strategies discussed.

Learn to locate the scoreboard in a security-minded CTF juice shop, using the inspector to gather information, guess URLs, and inspect JavaScript references ahead of a Dom eXistenZ attack.

Explore a dom-based xss challenge in a juice shop web app. Practice injecting scripts via input and iframes, and review scoreboard results plus prevention tips from a wasp cheat sheet.
