Cyber Security for Beginners

  Hacking involves a systematic process comprising five distinct phases. While not strictly adhering to a sequential order, these steps contribute to a comprehensive and effective approach when followed in a stepwise manner. Phases of Hacking: 1. Reconnaissance:    - Also known as Footprinting, this initial phase involves gathering preparatory information about the target. Information is collected regarding the network, host, and individuals involved. Two methods of Footprinting include active (directly interacting with the target, e.g., using Nmap) and passive (collecting information without direct access, e.g., from social media). 2. Scanning:    - This phase encompasses three types of scanning:       - Port scanning: Identifying open ports, live systems, and services on the host.       - Vulnerability scanning: Checking for exploitable weaknesses using automated tools.       - Network mapping: Determining the netwo...

 Hackers are broadly categorized into different types based on their intentions, skills, and activities in the realm of cyber security. Here are common types of hackers: 1. White Hat Hackers (Ethical Hackers):    - Work with organizations to identify and fix security vulnerabilities. Their aim is to improve security and protect systems. 2. Black Hat Hackers:    - Engage in hacking activities for malicious purposes, such as stealing data, spreading malware, or causing damage. These are often the stereotypical "bad" hackers. 3. Grey Hat Hackers:    - Operate between white hat and black hat hackers. They may hack without explicit permission but with the intent of notifying the target organization afterward. 4. Script Kiddies:    - Individuals with limited technical skills who use pre-written scripts or tools to carry out attacks. They often lack in-depth understanding but can still cause harm. 5. Hacktivist:    - Hackers motivated by s...

Value of Information   The value of information lies in its ability to contribute positively to decision-making, operations, and overall effectiveness. Key aspects of the value of information include: 1. Informed Decision-Making:    - Information provides the foundation for making informed and strategic decisions, minimizing uncertainty and risk. 2. Operational Efficiency:    - Well-managed and accessible information enhances operational efficiency by facilitating smooth workflows and processes. 3. Competitive Advantage:    - Organizations can gain a competitive edge by leveraging valuable information to understand market trends, customer preferences, and industry dynamics. 4. Innovation and Growth:    - Information fuels innovation and supports organizational growth by identifying opportunities, optimizing resources, and fostering adaptability. 5. Risk Management:    - Accurate and timely information is crucial for identifying and ...

 Cyber security careers encompass a diverse range of roles dedicated to protecting digital systems and data. Some common cyber security career paths include: 1. Cyber security Analyst: Monitor and analyze security threats, implement security measures, and respond to incidents. 2. Penetration Tester (Ethical Hacker): Assess system vulnerabilities by simulating cyber attacks to identify and fix security weaknesses. 3. Security Consultant: Advise organizations on improving their overall security posture, conducting risk assessments, and implementing security solutions. 4. Incident Responder:  Investigate and respond to security incidents, develop incident response plans, and mitigate the impact of breaches. 5. Security Architect:  Design and build secure information systems, considering factors like access controls, encryption, and network security. 6. Security Engineer:  Develop and implement security solutions, such as firewalls, antivirus software, and encryption pro...

What is Hacking? Hacking involves identifying and exploiting vulnerabilities in a system or network to gain unauthorized access to data and system resources. It is an unauthorized intrusion into information systems or networks, compromising security. For instance, exploiting default passwords to access stored data is a common hacking example. What is Ethical Hacking?  Ethical Hacking, also known as Penetration Testing, involves intruding into systems or networks to identify threats and vulnerabilities that malicious attackers could exploit, potentially leading to data loss, financial harm, or significant damages. The goal of ethical hacking is to enhance network or system security by addressing the identified vulnerabilities. Ethical hackers employ methods and tools similar to those used by malicious actors, but with explicit permission from authorized individuals to strengthen security and protect systems from potential attacks. It is crucial for ethical hackers to report all iden...
