Set of tools for generating new malware automatically using a variety of supplied propagation and payload mechanisms. Malicious hacker tools used to break into new machines remotelytrapdoor any mechanism that bypasses a normal security check it may allow unauthorized access to functionality in a program, or onto a compromised system. Code that installs other items on a machine that is under attack. It is normally included in the malware code first interested on to a compromised system to then import a larger malware package. At attack using code in a compromised Web site that exploits a browser vulnerability to attack a client system when the site is viewed. Code specific to a single vulnerability or set of vulnerabilities. Used to generate a large volume of data to attack networked computer systems, by carrying out some form of denial of service Do. S attack. Captures keystrokes on a compromised system. Code inserted into malware by an intruder, a logic bomb lies dormant until a predefined condition is met the code then triggers an unauthorized act. A type of virus that uses macro or scripting code, typically embedded in a document, and triggered when the document is viewed or edited, to run and replicated itself into other such documents. Software e. g. script, macro, or other portable instruction that can be shipped unchanged to a heterogeneous collection of platforms and execute with identical semanticsset of hacker tools used after attacker has broken into a computer system and gained root level access. Used to send large volumes of unwanted email.

A computer program that appears to have a useful function, but also has a hidden and potentially malicious function that evades security mechanisms, sometimes by exploiting legitimate authorizations of a system entity that invokes the Trojan horse program. Malware that, when executed, tries to replicate itself into other executable machine or script code, when it succeeds, the code is said to be infected. When the infected code is executed, the virus also executes. A computer program that can run independently and can propagate a complete working version of itself onto other hosts on a network usually by exploiting software vulnerabilities in the target system. Program activated on an infected machine that is activated to launch attacks on other machinesfocused on multi user, military and commercial systems, not applied to desktop computers.

Users specify security policy difference between a secure and insecure action is user intent Users can only make good decisions about something they understand. Research in security turning to HCI Humans are the last and often weakest link. Critical Infrastructure Systemstransportation, financial, energy, human health, agricultural health, communication, and cities and fixed infrastructure. Provides an excellent example of failure of critical infrastructure system involving computer control. Not caused by a malicious attack but influential in advancing concerns about cyber security for critical infrstructure. Started August 1. Total costs were estimated at more than 5 billion US dollars 5. Cascading Failure. Phase 5 Unplanned shifts of power across the region. Phase 6 Full cascade. Phase 7 Formation of islands. Causality can be described at multiple levels management, technologyCause limited reserves and untrimmed trees in the Cleveland control area, more failures than expected, insufficient understanding of system state through networked computer control Multiple failed systems MISO state estimator and alarms at First Energy, system integration that enabled the blackout to spread broadly without supporting adequate information exchange.

Worchester Air Traffic Communications. Maroochy Shire Sewage Spill. Blackout was influential for cyber security. The report asserts that there is not evidence that a cyber attack contributed to the blackout. Yet, the computer control difficulties did contribute. Increasing interdependency of the system and increased reliance on computer monitoring and control opened the path to deliberately caused failures like the 2. Difficult to define concept, commonly refers to the desires and expectations of individuals about how, when, what and to whom information about themselves is revealed to others. Contrasts with security, which concerns protection against malicious attackers seeking to steal data or disrupt operations. Influential classification and surveys from early 1.
