Hacking is a felony in the US and most other countries. When it is done by request and under a contract between an ethical hacker and an organization, it is OK! The difference is that the ethical hacker has authorization to probe the target. “The number of really gifted hackers in the world is very small, but there are lots of wannabes…”(-Dr. Charles C. Palmer, IBM) What is Hacking?Who are Hackers?: Who are Hackers? A school definition for the term hacker. Is someone who never goes to class, who in fact sleeps all day, and who spends the night pursuing recreational activities rather than studying. There are at least two common interpretations: Someone who bypasses the system’s access controls by taking advantage of security weaknesses left in the system by developers Someone who is both knowledgeable and skilled at computer programming, and who is a member of the hacker subculture, one with it’s own philosophy and code of ethicsHistory of Hackers: History of Hackers In December of 1947, the transistor was invented.

Most vulnerable Less resources Ignore or unaware of risks Large businesses with 100 or more employees Higher profile Larger networkIs Computer Hacking a Crime???: Computer hacking is broadly defined as any action that results in unauthorized interference with a computer, computer system or network. Computer hacking includes breaking into a computer with the intent to steal, damage, modify or monitor data or settings within the system. Significance Computer hacking is considered a crime in all countries; it is also a crime under federal and international law. Because a computer may be accessed from anywhere, a person may be charged with computer hacking on the state, federal and international level. Types Hacking often involves more than just unauthorized access to a computer. Computer hackers may access a computer in order to: steal financial information such as credit card access numbers; steal personal information (identity theft); harass (swatting); vandalize; gain access to other computers; launch computer attacks; or place malicious software (malware). Is Computer Hacking a Crime???Slide 19: Refers to sending a large number of emails to the victim resulting in the victim's Email account (in case of an individual) or Mail servers (in case of a company or an email service provider) crashing. Email BombingSlide 20: Altering raw data just before it is processed by a computer and then changing it back after the processing is completed. Electricity Boards in India have been victims to data diddling programs inserted when private parties were computerizing their systems. Data DiddlingSlide 21: Used for the commission of financial crimes. Key here is to make the alteration so insignificant that in a single case it would go completely unnoticed. E.g. a bank employee inserts a program, into the bank's servers, that deducts a small amount of money (say Rs. 5 a month) from the account of every customer. No account holder will probably notice this unauthorized debit, but the bank employee will make a sizable amount of money every month. Salami AttacksSlide 22: Involves flooding a computer resource with more requests than it can handle. Causes the resource (e.g. a web server) to crash thereby denying authorized users the service offered by the resource. Denial of Service AttackSlide 23: Programs that attach themselves to a computer or a file Circulate themselves to other files and to other computers on a network Affect the data on a computer, either by altering or deleting it Virus AttacksSlide 24: Do not need the host to attach themselves to. Make functional copies of themselves and do this repeatedly till they eat up all the available space on a computer's memory. Worm AttacksSlide 25: Event dependent programs. Programs are created to do something only when a certain event (known as a trigger event ) occurs. E.g . even some viruses may be termed logic bombs because they lie dormant all through the year and become active only on a particular date (like the Chernobyl virus). Logic BombsSlide 26: Occurs when someone forcefully takes control of a website (by cracking the password and later changing it). Web JackingTypes of Cyber attacks by %(Source- FBI): Financial fraud 11% Sabotage of data/networks 17% Theft of proprietary information 20% System penetration from the outside 25% Denial of service 27% Unauthorized access by insiders 71% Employee abuse of internet privileges 79% Viruses 85% Types of Cyber attacks by % (Source- FBI)Industry Response: Industry Response Software analyst meet to discuss the latest technology Demand for security professionals Many companies have spent money on security and repairs Microsoft estimated five billion dollars in 2010 www.Getsafeonline.com http://www.homeoffice.gov.uk/Slide 30: Use anti-virus software and firewalls - keep them up to date Keep your operating system up to date with critical security updates and patches Don't open emails or attachments from unknown sources Use hard-to-guess passwords . Don’t use words found in a dictionary. Remember that password cracking tools exist Don't share access to your computers with strangers Back-up your computer data on disks or CDs often If you have a Wi-Fi network, password protect it Disconnect from the Internet when not in use Reevaluate your security on a regular basis Make sure your employees and family members know this info too! Protect your ComputersIntrusion Detection: Intrusion Detection Intrusion detection systems are the next generation of security beyond firewall protection Host Based IDS: For servers that contain sensitive information. Network Based IDS: Monitors certain network segments. Gives administrators a more proactive approach to stopping a potential threat .Introduction to Detection: Introduction to DetectionHOW TO DEALWITH THIS PROBLEM: HOW TO DEALWITH THIS PROBLEM International Agreements and Cooperation –Essential due to the Worldwide Nature of the Internet Software and Hardware defenses (e.g., antispam , antivirus software, firewalls) Other practical steps….Practical Steps for prevention of Cyber Crime: Avoid disclosing any information pertaining to oneself. Avoid sending any photograph online particularly to strangers. Use latest and up date anti virus software. Keep back up volumes. Never send your credit card number to any site that is not secured. Use of firewalls may be beneficial. Practical Steps for prevention of Cyber CrimeLaws, Fines, and Penalties: Laws, Fines, and Penalties Hackers, virus and worm writers could get 20 years to life in federal prison. Anyone who uses computers to cause death or bodily harm, such as bringing down power grids or airport control centers, can get the maximum sentence. The sentence is increased by 25% if they steal personal information. The sentence is increased by 50% if they share the stolen information. If posted on the Internet, sentence is doubled!Slide 36: Tampering with computer source documents Hacking with computer system Publishing of information which is obscene in electronic form Misrepresentation Breach of confidentiality and privacy Publishing digital signature false in certain particulars Publication of unlawful document for fraudulent purpose Can be charged up to rupees 1 to 3 Lakhs OR Can get imprisonment for 2 to 10 Years OR Both can be implemented according to the law Person found doing activities such asConclusion: Conclusion User awareness is key to a secure computer/network Do not open suspicious files/emails Verify ActiveX/Java prompts Avoid using P2P programs Avoid downloading freeware If attacked, disconnect the network. Do not turn off the computer Without Careful Attention To These Issues, The Uncontrolled Interconnection Of Existing Systems, On Which People And Organizations Are Critically Dependent, Will Continue To Create Huge, Ill-defined And Defenseless Super - Systems. So We Must Pay Attention To All Those Issues And Protect The World From Cyber Crime. You do not have the permission to view this presentation.
