Cards

Term
IP Internet Protocol
Definition
-Connectionless protocol that's responsible for network addressing
-Provides routing between networks
Term
TCP Transmission Control Protocol
Definition
Connection oriented protocol that establishes connections between endpoints and guarantees delivery
Term
UDP User Datagram Protocol
Definition
Connectionless oriented with no guarantee of delivery
Term
TCP Threeway Handshake
Definition
-Client sends syn to server
-Server must have open port that can accept syn. Send ACK packet and establishes connection
-Client receives Syn/Ack from server and responds with an ACK packet and establishes connection
Term
DNSSEC
Definition
-Adds security to original DNS spec
-Protected Zones
-Digitally signed authenticating dns server
-Not encrypted
-Defense for DNS poisoning and DNS Hijacking
-Port 53
Term
SRTP
Definition
-Adds AES encryption to audio and video
-Security protocol adds confidentiality, message authentication and replay protection
-Used to secure VOIP Traffic
-Adds HMAC hashing with SHA1
Term
S/MIME
Definition
Secure Multiprotocol Internet Mail Extensions
Term
S/MIME Challenges in Implementation
Definition
-Sending and receiving users required to obtain key/certificate
-End to End Encryption

Term
LDAPS (LDAP over SSL)
Definition
-Port 636
-Secures Traffic between client and server over ssl/tls

Term
FTPS
Definition
-Secure file transfers using SSL
-Encryption can be turned off if other encryption is in use like IPSec
-TCP Ports 989, 990
Term
SFTP - Secure Shell File Transfer
Definition
Port 22 file transfer
Term
SNMPV3
Definition
-UDP Port 161

-Secure protocol
Term
SSL/TLS
Definition
-SSL no longer used replaced by TLS
-Adds confidentiality and data integrity by encapsulating other protocols
Term
HTTPS
Definition
