11-14 Hacking The obsessive use of computers Unauthorized access/use of networked computers Breaking and Entering Hacking into a computer system and reading files, but neither stealing nor damaging anything Cracker A malicious or criminal hacker who maintains knowledge of vulnerabilities found for private advantage
15
11-15 Common Hacking Tactics
16
11-16 Cyber Theft Many computer crimes involve theft of money Most are “inside jobs” that involve unauthorized network entry and alteration of databases to cover the tracks of the employees involved Many attacks occur through the Internet Most companies don’t reveal that they have been targets or victims of cyber crime
17
11-17 Cyberterrorism The leveraging of an organization’s or government’s computers and information –Particularly through the Internet –To cause physical, real-world harm or severe disruption of infrastructure Can have serious, large-scale influence –Can weaken a country’s economy –Can affect Internet-based businesses
18
11-18 Cyberterrorism Life-support at Antarctic research station turned off Release of untreated sewage into waterways Examples of Cyberterrorism Nonessential systems shut down in nuclear power plants Estonian government ministry and banks knocked offline No successful attacks reported yet in the U.S.

55
11-55 Internetworked Security Defenses Firewalls Gatekeeper system that protects a company’s intranets and other computer networks from intrusion Provides a filter and safe transfer point for access to/from the Internet and other networks Important for individuals who connect to the Internet with DSL or cable modems Can deter hacking, but can’t prevent it
56
11-56 Internet and Intranet Firewalls
57
11-57 Denial of Service Attacks The victim’s ISP The victim’s website Zombie or slave computers commandeered by cyber criminals Denial of service attacks depend on three layers of networked computer systems
58
11-58 Defending Against Denial of Service At victim’s Website Create backup servers and network connections At the ISP Monitor & block traffic spikes At Zombie machines Set/enforce security policies Scan for vulnerabilities
59
11-59 Internetworked Security Defenses Email Monitoring –Use content monitoring software to scan for troublesome words Virus Defenses –Centralize the updating and distribution of antivirus software –Use a security suite that integrates virus protection with firewalls, Web security, and content blocking features

11-61 Other Security Measures Computer devices measure physical traits that make each individual unique Voice recognition, fingerprints, retina scan Biometrics Prevents computer failures or minimizes its effects Preventive maintenance Computer Failure Controls Arrange backups with a disaster recover organization
62
11-62 Other Security Measures In the event of a system failure, fault-tolerant systems have redundant processors, peripherals, and software –Fail-over: shifts to back up components –Fail-safe: the system continues to operate at the same level –Fail-soft: the system continues to operate at a reduced but acceptable level
63
11-63 Other Security Measures A disaster recovery plan contains formalized procedures to follow in the event of a disaster Which employees will participate What their duties will be What hardware, software, and facilities will be used Priority of applications that will be processed Use of alternative facilities Offsite storage of databases
64
