- 1Five major security components are required when we talk about security: Data privacy and integrity
Authentication, authorization, and accounting (AAA)
Segmentation
Monitoring
Policy - 2Originally named the Rijndael algorithm, is a block cipher that offers much stronger protection than the RC4 streaming cipherAES algorithm
- 3is a streaming cipher used in technologies that are often used to protect Internet traffic, such as Secure Sockets Layer (SSL)e RC4 algorithm
- 4These security technologies exist to obscure information and is mandatory to provide proper data privacycipher encryption
- 5is the verification of identity and credentialsAuthentication
- 6Determines if the device or user is authorized to have access to network resourcesAuthorization
- 7Is tracking the use of network resources by users and devicesAccounting
- 8The 802.11-2012 or 802.11i, defines 2 main methods of authentication:802.1X/EAP and Preshared key or phasphrase
- 9 Two stations (STAs) must authenticate and associate with each other, as well as create dynamic encryption keys through a process known as the 4-Way Handshakerobust security network associations (RSNAs)
- 10 Validates the credentials of the supplicant that is requesting access and notifies the authenticator that the supplicant has been authorized Maintains a user database or may proxy with an external database, such as an LDAP database, to authenticate user credentialsAuthentication Server (AS)
- 11maintains two virtual ports: Uncontrolled: allows EAP authentication traffic to pass through Controlled: blocks all other traffic until the supplicant has been authenticatedAuthenticator
- 12A host with software that requests authentication and access to network resources is:Supplicant
- 13Segmentation can be achieved through a variety of means: Firewalls
Routers
VPNs
VLANs - 14is another approach to restricting system access to authorized users. Separate roles can be created, such as a sales role or a marketing role. Individuals or groups of users are assigned to one of these rolesRole-based Access Control (RBAC)
- 15Role-based Access Control (RBAC) has three main components: Users
Roles
Permissions - 16are typically not recommended to provide wireless security in the enterprise due to the overhead and because faster, more secure layer 2 solutions are now availableVPNs
- 17Provide encryption, encapsulation, authentication, and data integrity Use secure tunnelingVPNs
- 18Unlike an IPsec VPN, this vpn does not require the installation and configuration of client software on the end user’s computerSSL VPN
