Information Assurance

Question 1

1 ) Following are some of the advantages of synchronization of data in to access the same data locally

Data becomes centralized and available to all parties and any inconsistency can not go unnoticed

Helps an administrator manage errors and discrepancies in data from a single interface and is able to detect suspicious activity

More secure data hence there is greater reliability

Provides better control

Synchronization allows flexibility to users

Provides a secure , centralized computing environment

Able to maintain a standard for authorization of data

Encryption of

data provides a higher level of security

Deployment of data becomes more secure in such an environment

2a ) Having centralized network management is important when it comes to network security . LAN and WAN can be analyzed by protocols , physical network types and network devices . Following are some security measures that can be taken in these areas in the U .S

PROTOCOL

DNS (Domain Name Service )- The DNS should be kept invisible externally (Internet . A firewall should not give out any information on the hosts and should only resolve firewall addresses

DCHP (Dynamic Host Configuration Protocol )- An IP address must uniquely identify a machine . Having a static IP is more secure if a DCHP is used .Physical Network Types

Ethernet- Using switches provides better security . Any unused sockets must be disconnected . To physically secure networks conduit can be used .Leased Lines- The leased lines can be encrypted either by hardware or software

ATM (Asynchronous Transfer Mode )- The complexity of...
