Computer crime involves: Theft by computer (including identity theft and phis hing) Software piracy and intellectual property misuse Software sabotage (malw are- including worms, viruses, Trojan horses, e tc.) Hacking and electronic trespassing. The computer crime dossier Computer crime: any crime accomplished through knowledge or use of computer technology Businesses and government institutions lose billions of dollars every year to computer criminals The majority of crimes is committed by company insiders Typically covered up or not reported to authorities to avoid embarrassment According to a 2001 survey of over 500 companies and government agencies: 85% detected computer security breaches in the preceding 12 months Financial losses due to security breaches topped $377 million 70% reported that Internet connections were frequent points of attack Only 31% said that internal systems were frequent points of attack. Theft by computer Theft is the most common form of computer crime. Computers are used to steal Money Goods Information Computer resources One common type of computer theft today is the actual theft of computers, such as notebook and PDAs Notebook and PDAs are expensive Data stored on a computer can be more valuable Denial o f Service ( DOS) Attacks bombard servers and Web sites with so much bogus traffic that they are effectively shut down networks, denying service to legitimate customers and clients. Computer security Protecting computer systems and the information they contain against unwanted access, damage, modification, or destruction Two inherent characteristics A computer does exactly what it is programmed to do, including reveal sensitive information Can be reprogrammed Any computer can do only with it is programmed to do Cannot protect itself from malfunctions or deliberate attacks Physical access restrictions Identify people attempting to access computer equipment Usually using a number of tools and techniques. Depending on the security system, you might be granted access to a computer based on: Something you have A key, an ID card with a photo, or a smart card containing digitally encoded identification in a built-in memory chip Something you know A password, an ID number, a lock combination, or a piece of personal history, such as your mother’s maiden name Something you do Your signature or your typing speed and error patterns Something about you A voice print, fingerprint, retinal scan, facial feature scan, or other measurement of individual body characteristics; these measurements are collectively called biometrics. Passwords The most common tool for restricting access to a computer system Effective passwords are: Not real words Not names Changed frequently Kept secret A combination of letters and numbers Firewalls, encryption, and audits Firewalls A locked gate that opens only for information packets that can pass one or more security inspections Can be used for both corporations and individuals. Firewalls, encryption, and audits Encryption Encrypts a message by applying a secret numeric al code, called an encryption key The message is sent as an indecipherable garble of characters After it is received, it will be reconstructed with a matching key Audit-control software Monitor and record computer transactions as they happen so auditor can trace and identify suspicious computer activity after the fact To avoid the case that electromagnetic signals emanating from the computer hardware is “heard” so that some sensitive information is read. Backups and other precautions A power surge or failure can wipe out well protected data Uninterruptible power supply (UPS) Can protect computers from data loss during power failures Surge protectors Do not help during power failure Can shield electronic equipment from power spikes Backup Disasters cannot be avoided completely, so we…
