IT Vocab IT = information technology Server Client or host Public – open access Private – limited access Client or host Thin - diskless Workstation – fully functioning computer system

IT Vocab A computing system : a configuration of one or more computers along with the software and data.

Tenets of IT Security CS5493

A I C Availability - assets are available in a timely manner. Integrity – assets remain in their expected states. Confidentiality - assets have access controls

What are assets? An asset is something of value: Hardware Software Data Employees Equipment Etc.

AIC and Threat Categories Denial or destruction threats Alteration threats Improper disclosure threats

The Domains of IT Infrastructure User domain Workstation domain LAN domain LAN-to-WAN domain WAN domain Remote Access domain Server (System)/Application domain

Domain Breakdown The IT infrastructure is broken into different domains so security policy can be organized effectively.

IT Domain Security Policy A comprehensive security plan can be devised by considering each separate domain. Identify the threats and vulnerabilities Devise a strategy for eliminating the vulnerabilities.

Vulnerabilities Examples: User – lack of awareness or concern for security policy. Workstation domain – unauthorized access LAN – spreading of malicious software WAN – malicious attacks by anonymous sources Remote access – Data leakage due to loss or theft of electronic devise Server/App – Data loss due to software and hardware failures.

Domain Threat Targets User – misuse of resources, social engineering Workstation – OS, applications LAN – hubs, cables, supporting software, etc. WAN – routers, firewalls, supporting software, etc. Remote Access – VPN Server Application – e-mail, file services, database, etc.
