Unscrupulous programmers create a virus program. They hide the virus in a Word document and attach the Word document to an e-mail message.Step 2. They use the Internet to send the e-mail message to thousands of users around the world.Step 3b. Other users do not recognize the name of the sender of the e-mail message. These users do not open the e-mail message. Instead they delete the e-mail message. These users’ computers are not infected with the virus.Step 3a. Some users open the attachment and their computers become infected with the virus.Internet and Network AttacksHow can you protect your system from a macro virus?Set macro security level in applications that allow you to write macrosSet security level so that warning displays that document contains macroMacros are instructions saved in an application, such as word processing or spreadsheet programInternet and Network AttacksWhat is an antivirus program?Identifies and removes computer virusesMost also protect against worms and Trojan horsesInternet and Network AttacksWhat is a virus signature?Specific pattern of virus code that does damageAlso called virus definitionAntivirus programs look for virus signaturesKeeps file in separate area of hard diskInternet and Network AttacksHow does an antivirus program inoculate a program file?Records Records information information about program such about program such as file size and as file size and creation creation datedateAttempts Attempts to remove to remove any detected any detected virusvirusUses Uses information information to detect if to detect if virus tampers virus tampers with filewith fileQuarantinesQuarantines infected infected files that it files that it cannot cannot removeremoveInternet and Network AttacksWhat are some tips for preventing virus, worm, and Trojan horse infections?Install a personalfirewall programIf the antivirus program flags an e-mail attachment as infected, delete the attachment immediatelyNever start a computer with removable media insertedNever open an e-mail attachment unless you are expecting it and it is from a trusted sourceInstall an antivirus program on all of your computersCheck all downloaded programs for viruses, worms, or Trojan horsesInternet and Network AttacksWhat are a denial of service attack, back door and spoofing?A denial of service attack is an assault whichdisrupts computer access to an Internet service such as the Web or e-mailA back door is a program or set of instructionsin a program that allow users to bypasssecurity controls when accessing a computerresourceSpoofing is a technique intruders use to maketheir network or Internet transmissionappear legitimate to a victim computer ornetworkInternet and Network AttacksWhat is a firewall?Security system consisting of hardware and/or software that prevents unauthorized intrusionInternet and Network AttacksWhat is a personal firewall?Program that protects personal computer and its data from unauthorized intrusionsMonitors transmissions to and from computerInforms you of attempted intrusionAuthorized Access and UseHow can companies protect against hackers?Intrusion detection softwareIntrusion detection softwareanalyzes network traffic, assesses analyzes network traffic, assesses system vulnerabilities,
