Introduction of Cyber Security
- 1. WHAT IS HACKING? • Hacking often refers to the unauthorized intrusion into a network or computer; normally carried out by one or more “hackers.” However, a hacker can be anyone. They can be an individual like you or me. They can work solo or be employed by an organization that has the motive to disrupt something or cause havoc–– unnecessarily. Often, they look to alter security systems to achieve their goal, which differs from the actual purpose of the system.
- 2. WHY HACK? • PROFIT • -Information can be sold • -Information can be used to steal • PROTEST • -Hactivism : A Hacktivist is someone utilized technology to announce a social, ideological, religious or political message. • CHALLANGE • - Fun , problem - solvingskill, the thrill of power
- 3. EFFECTS OF HACKING • Damage to information • Theft of information - Credit card details , social security numbers, identity fraud, email addressed • Compromise/damage of system • Use of victim machines as “zombies” • Businesses may suffer from damage reputation and lawsuits • Business secrets could be stolen and sold to competitors • Computing system/ infrastucture could suffer from performance degrading as the resources used for malicious activites
- 4. TYPES OF HACKER White, black, and grey refer to the relationship between the hacker and the systems they are attacking. Black Hat’ Hackers A black-hat hacker is an individual who attempts to gain unauthorized entry into a system or network to exploit them for malicious reasons. The black-hat hacker does not have any permission or authority to compromise their targets. They try to inflict damage by compromising security systems, altering functions of websites and networks, or shutting down systems. They often do so to steal or gain access to passwords, financial information, and other personal data.
- 5. TYPES OF HACKER ‘White Hat’ Hackers White-hat hackers, on the other hand, are deemed to be the good guys, working with organizations to strengthen the security of a system. A white hat has permission to engage the targets and to compromise them within the prescribed rules of engagement. They are often referred to as ethical hackers. This individual specializes in ethical hacking tools, techniques, and methodologies to secure an organization’s information systems. Unlike black-hat hackers, ethical hackers exploit security networks and look for backdoors when they are legally permitted to do so. White-hat hackers always disclose every vulnerability they find in the company’s security system so that it can be fixed before they are being exploited by malicious actors.
- 6. TYPES OF HACKER ‘Grey Hat’ Hackers Grey hats exploit networks and computer systems in the way that black hats do, but do so without any malicious intent, disclosing all loopholes and vulnerabilities to law enforcement agencies or intelligence agencies. Usually, grey-hat hackers surf the net and hack into computer systems to notify the administrator or the owner that their system/network contains one or more vulnerabilities that must be fixed immediately. Grey hats may also extort the hacked, offering to correct the defect for a nominal fee.
- 7. TYPES OF ATTACKS Password Cracking Attacks Network Attacks Man-in-the-middle Attcks Identity Spoofing Interception Eacesdropping Backdoor Attacks and many more..
- 8. HOW TO HACK? • Many of the hacking tools and guides are available on the internet • BackTrack is a Linux distro with many tools : Metasploits, SQL map Nmap, Ophcrack, Wireshark, Hydra and many more • The real reason for BackTrack development are for digital forensics and penetration testing
- 9. KALI LINUX Kali Linux is an open source project that is maintained and funded by Offensive Security, a provider of world-class information security training and penetration testing services. In addition to Kali Linux, Offensive Security also maintains the Exploit Database and the free online course, Metasploit Unleashed.
