Study for Disaster Recovery Test 1

QuestionAnswer
3 Goals of Computer Security Confidentiality, Integrity, Availability
Confidentiality Controls are USER IDs and PASSWORDS. - Means PRIVACY.
Integrity Only authorized users - Prevents unauthorized users from modification - Maintain internal & external consistency of data and programs
Availability Denial of Server (DoS) - Loss of information system capabilities because of natural disasters - Equipment failures during normal use
Threat A category of objects, persons or other entities that pose a potential risk of loss to an asset
Asset An organizational resource that is being protected
List 3 Assets Computer, Data, People
Vulnerability A weakness or fault in the protection mechanisms that are intended to protect information and information assets from attack or damage
Exploit - Verb Act of breaking into a system. - EXAMPLE: The hackers exploited the zero day vulnerability in Windows 7.
Exploit - Noun Weakness/Poor Code - EXAMPLE: There is a zero day exploit in Windows 7.
Control Represents security mechanisms, policies or procedures that can successfully counter attack, reduce risk, resolve vulnerabilities
Lists Examples of Control Firewall, IDS, Usernames/Passwords, Encyption, Physical Security
Intellectual Property Defines the ownership of ideas and control over the tangible or virtual representation of those ideas. - Examples: copyright, trademarks, patents
Software Piracy Most common IP breach is the unlawful use or duplication of software-based intellectual property
Hackers People who use and create computer software to gain access to information illegally.
Cyberterrorists Hacks systems to conduct terrorist’s activities through network or Internet pathways.
Denial of Service (DoS) Seeks to deny legitimate users access to services by either tying up server’s available resources or causing it to shut down
Virus Segments of code that perform malicious actions.
Worm Malicious programs that replication themselves constantly without requiring another program to provide a safe environment for replication.
Polymorphism A threat that changes its appearance shape overtime, making it undetectable by techniques that look for preconfigured signatures.
Social Engineering Attack Getting the computer user to perform an action that enables the infection. - Most Used Method = *PHONE*
Virus Attacks The source of the most financial loss
Risk Identification The process of examining and documenting the security posture of an organization’s IT and the risks it faces - **INFORMATION TECHNOLOGY
Risk Control The process of applying controls to reduce the risks to an organizations data and information systems - **DATA & INFORMATION SYSTEMS
Risk Management Identifying vulnerabilities in an organization’s information systems and taking carefully reasoned steps to ensure the confidentiality, integrity and availability of all the components in the organization’s information system - **VULNERABILITIES
Risk Assessment Assigns a risk rating or score to each information asset - **RATING or SCORE
Likelihood The probability that a specific vulnerability within an organization will be successfully attacked
Residual Risk The risk that remains to the information asset even after the existing control has been applied
List the 4 Control Strategies Avoidance, Transference, Mitigation, Acceptance
Avoidance Prevent exploitation of the vulnerability - Preferred approach - Safeguards
Transference Shift the risk to other assets - Buy insurance - Outsource
Mitigation Reduce the impact - Incident response plan - Disaster recovery plan
Acceptance DO NOTHING
