Beginner's Guide to Cybersecurity - Complete Course 2023 (ITA)

Technical Aspects of Cybersecurity

• 💻
  The social engineer is like a psychologist with a specialization in computer science, using psychological levers and technical knowledge to manipulate people and compromise the human factor in cybersecurity.
• 💡
  The effectiveness of hardware and software security measures is rendered useless if a social engineer is able to manipulate and deceive their victim using psychological tactics.
• 💡
  The methodology includes steps such as scanning, exploitation, privilege escalation, and post-exploitation, highlighting the structured approach taken in cybersecurity.
• 💻
  The privilege escalation phase in cybersecurity involves exploiting local misconfigurations or vulnerabilities to obtain a privileged shell, allowing for greater access and control within the target machine.
• 🌐
  The Connect Scan, a type of scan performed using Zen Map, completes the three-way handshake and establishes communication, making it useful for analyzing the TCP protocol.
• 💡
  The layering concept in cybersecurity, specifically the fusion between levels of the OSI model, is crucial in understanding how different protocols work together to manage logical addressing and ensure successful packet transmission.
• 💻
  The analysis of web portals and web applications is crucial in external penetration testing, as accessing the target network through vulnerabilities in standard network protocols is more difficult, while the defense walls are stronger on the outside.
• 🛡️
  The attacker can carry out a DHCP server attack by sending a series of requests to exhaust the pool of IP addresses that the legitimate DHCP server can assign, allowing the attacker to introduce their own DHCP server and divert network traffic to their network.

Human Factors in Cybersecurity

• 🤔
  The human factor in information security is not solely dependent on technology, but rather encompasses the role and responsibility of individuals within an organization.
• 💼
  Mitnick's transition from being a hacker to becoming the CEO of a cybersecurity consulting firm highlights the potential for individuals with a deep understanding of hacking techniques to contribute positively to the field of cybersecurity.
