Acronyms

This is a hardware chip on the motherboard included on many newer laptops. Includes a unique RSA asymmetric key, and it can generate and store other keys used for encryption, decryption, and authentication. Provides full disk encryption.

• TPM

• STP

• IPS

• MD5

Used within Microsoft Windows to manage users and computers. It is implemented on a domain controller within a domain. Administrators use it to create password policies, lock down the GUI, configure host-based firewalls, and much more. Remote wipe, or remote sanitize, erases all data on lost devices. Full disk encryption protects the data on the device if it is lost.

• RA

• SDLM

• CA

• GPO

Protocol used to synchronize computer times.

• TFTP

• NTP

• UTP

• NIPS

An extension of a host-based IDS. Designed to react in real time to catch an attack in action.

• HIPS

• DHCP

• L2TP

• PPTP

Provides cloud customers with an easy-to-configure operating system and on-demand computing capabilities.

• POTS

• PaaS

• IaaS

• PPTP

A hash function used for integrity. It creates fixed length hashes of 128, 160, 256, or 320 bits.

• PPTP

• RIPEMD

• AES

• RC4

A hashing function used to provide integrity. Uses 128 bits. A hash is simply a number created by applying the algorithm to a file or message at different times. The hashes are compared to each other to verify that integrity has been maintained.

• BIA

• 3DES

• MD5

• MAC

Newer security protocol used to protect wireless transmissions. It supports CCMP for encryption, which is based on AES and stronger than TKIP which was originally released with WPA. In Enterprise Mode, it can use RADIUS to support 802.1x authentication. In personal mode, it uses a preshared key (PSK).

• WPA2

• WAP

• PEAP

• HMAC

Access control model that uses sensitivity labels assigned to objects and subjects. SELinux is a trusted operating system platform using the MAC model. Other access control models are DAC and RBAC.

• ARO

• NAC

• MAC

• ECC

Tunneling protocol used with VPNs. Uses TCP port 1723.

• RSTP

• HTTP

• TFTP

• PPTP
