Sys Ops - Module 1-5b and c

(Range 1-126) /8 255.0.0.0

Issue certificates for users permitted by the CA

Way to partition networks into logical segments or groups for easier administration,special 32bit # with device’s IP add

(Range 128-191) /16 255.255.0.0

_ key consist of a public key, which is freely available, and a private key, which is kept secret.

Term for computer software providing services to software applications beyond those available from the operating system

Publishes PKI digital certificates

Designation used in routing to send packets to remote network

This authentication factor is the most common form. Usually this is a password or PIN

IPv6 annotated as eight groups of four _ digits

The use of two or more authentication factors.

_ key scheme handles both encryption and decryption. Users possess the same key to send and open encrypted messa

Any connected network device (computer, router, printer, etc.)

DoD successfully deployed program providing secure access to its communications networks

/_ = 255.255.255.0 or (binary) 11111111.11111111.11111111.00000000

Password Policy dictates how passwords in an organization will be structured.

Biometric authentication based on physical, genetic, or human characteristics & maybe the hardest to forge or spoof

Location can be used as an authentication factor.

Address used by applications and hosts to send information to all network nodes

(Range 192-223) /24 255.255.255.0

(Range 224-239) used only for multicasting

IPv4 annotated as Dotted-decimal (172.16.30.5)

Related to the “something you know” authenticationfactor. This factor is a performance-based version of authentication.

/_ = 255.0.0.0 or (binary) 11111111.00000000.00000000.00000000

AKA Network ID, Designation used in routing to send packets to remote network, Uniquely identifies each network

Revoking a certificate, invalidates a certificate before its expiration date. Stores revoked certificates

(Range 240-254) experimental use only

Internet Protocol (IP)

Transmission Control Protocol (TCP)

DoD PKI program provides most of its members with three types of credentials:

Logical address used to define a single host (device) on network

Something only you should physically possess. This is best done in conjunction with another authentication factor.

IP Address can be either IPv4 or IPv8

/_ = 255.255.0.0 or (binary) 11111111.11111111.00000000.00000000

Network Addressing is TCP/IP developed by DoD & the most popular networking protocol utilized on modern networks.
