Hacking is defined as illegally entering a computer system and making unauthorized changes to files and data. Crackers are individuals who gain illegal access to networks with malicious intent to damage systems. Criminal hacking specifically refers to manipulating information within a system in a negative way. Signs of a hack include discovering unauthorized emails or missing/moved files. If hacking is suspected, the most important step is to disconnect from the internet to protect information while also allowing security logs to be reviewed. Organizations are increasingly hiring ethical hackers to test security from an intruder's perspective in order to evaluate vulnerabilities.basic knowhow hacking

Hacking refers to attempting to gain unauthorized access to computer systems or networks. There are different types of hackers, including white hat hackers who test security systems to help organizations, black hat hackers who access systems maliciously, and gray hat hackers whose activities fall between white and black. Common types of hacking include website, email, network, password, and computer hacking through techniques like sniffing passwords, spoofing addresses, cracking encryption, brute force guessing, and exploiting poor web application coding. Organizations can help prevent hacking by employing ethical hackers to test security, not exposing passwords to untrusted sites, closing internet access when not in use, and having basic internet knowledge.Ethical hacking

Introduction To Ethical HackingNeel Kamal

This document introduces the concept of ethical hacking. It begins by defining hacking as finding solutions to real-life problems, and clarifies that the original meaning of "hack" was not related to computers. It then discusses how the term entered computer culture at MIT in the 1960s, where hackers were students who solved problems in innovative ways, unlike "tools" who just attended class. The document outlines some traits of good hacks and provides examples. It emphasizes that media misconstrues hackers as criminals, and explains that real hackers have strong ethics and help catch cyber criminals, unlike crackers who hack systems illegally. The rest of the document provides an overview of skills, subjects, and basic concepts needed for ethical hacking.Assignment 4

Hackers illegally break into computer systems for personal gain or damage, often to steal financial information. They have in-depth technical knowledge that allows them to create hacking tools. Crackers also illegally access computer systems, but lack the technical skills of hackers. Crackers rely more on pre-existing hacking tools and cause damage through actions like replacing websites. Both hackers and crackers commit cybercrimes, but hackers do so using their own technical abilities while crackers rely on existing tools.ICT Form 4: Hacking

Hacking involves unauthorized access to computer systems. It is done by hackers, who have an in-depth knowledge of computers and programming. While hacking can sometimes help recover lost information, it is usually illegal and can harm privacy or destroy work. To prevent hacking, firewalls are used to limit unauthorized access to networks and computer activities. Though hackers have innovative skills, hacking should not enable criminal plans or harm others.my new HACKING

Hacking involves exploring systems and programming skills, while cracking uses those skills illegally. Hackers have various motivations including fun, profit, challenges, and exposing weaknesses. There are different types of hackers such as white hats who are professional security experts and black hats who are criminal hackers. Without hackers, many programming languages and operating systems would not exist. Crackers create security issues but also jobs to improve security. Common attacks include social engineering, denial of service attacks, and SQL injection. Once inside a system, a hacker can modify files and logs, install backdoors, and attack other systems. Hacking overall has benefited the computer industry by advancing programming and security.Basic Introduction to hacking

Logic bombs are malicious codes hidden in software that execute when predefined conditions are met, such as a specific date or time. They can damage systems by deleting files or entirely wiping computers. Spoofing attacks impersonate other devices or users on a network to launch attacks, steal data, or bypass access controls. Types of spoofing include IP address spoofing, ARP spoofing, DNS server spoofing, web spoofing, and email spoofing. Phishing is a form of deception designed to steal personal information like credit card numbers or passwords by tricking users into entering information on fake websites or responding to fraudulent emails.Introduction to Ethical Hacking (Basics)

Hacking refers to activities aimed at exploiting security flaws to obtain unauthorized access to secured networks and private information. There are different types of hackers, including black hats who hack maliciously, white hats who are ethical hackers, and script kiddies who use tools created by black hats. Common hacking methods include password guessing, software exploitation, backdoors, and trojans. Once inside a network, a hacker can steal or modify files, install backdoors, and attack other systems. Intrusion detection and prevention systems can help monitor for hacking attempts. Hacking is a felony in most countries and can carry heavy fines and prison sentences if prosecuted.Hacking 1224807880385377-9

- 3. Hacking generally refers to act of a person abusing computer access, breaking into computers, or using computers without authorization. An intruder or attacker is a person who carries out an attack.
- 4. There are in essence two types of hackers, often referred to as 1.White-hat hackers. 2.Black-hat hackers. White hat hackers enjoy learning and working with computer systems, and consequently gains a deeper understanding of the subject. Black-hat hackers often called as Crackers called by White-hat hackers.
- 6. Steal credit card numbers. Steal passwords to other systems. To steal programs or files. Read others mails.
- 7. Files disappear or are modified unexpectedly. Strange files appear or grow in size unexpectedly. Programs stop working as expected. Your internet connection slows dramatically for an extended period. The computer starts crashing frequently.
- 8. Gathering information. 1.port scanning. 2.packet sniffing. Launching attack 1.Denial of Service(DOS). 2.Password cracking. 3.Packet Sequence attacks. 4.Operating System exploits. 5.FTP(File Transfer Protocol). 6.Fore Core Dumping.
- 9. Server-side security. It is a very large and complex area. Client-side security:-This contains 3 areas 1.Anti-virus security. 2.Personal Firewall. 3.Encryption.
- 12. Encryption programs basically scramble the original file so that it is unreadable to anyone without the correct password to de-scramble the file. The key to data encryption is to choose your passwords carefully, and change your passwords frequently.
- 13. The main appeal to me is to ability to communicate complex ideas in a fast, cheap and creative way. A level-headed approach should be taken by all internet users to protect their privacy and security online. When the true meaning of hacking is realized people will be able to publicly declare themselves as hackers.
