- Provides connectivity between two host.
- No error correction, best effort delivery.

NETWORK = Network Address and Best Path Determination
- Provides reliable transfer of data across media.
- Physical addressing, network topology, error notification,
flow control.

TRANSPORT = End to end connection
- Concerned with transportation issues between host.
- Data transport reliability.
- Establish, maintain, terminate virtual circuit.
- Fault detection and recovery information flow control.

SESSION = Interhost Session
- Establishes, manages and terminates sessions between applications.


PRESENTATION = Data Presentation
- Ensure that the data is readable when receiving the system.
- Format of data.
- Data structures.
- Nagiotates data transfer syntax for application layer.

Protection on Network Attack

PROTECTION ON NETWORK ATTACK :)

Encryption
Policy ( Rules) - obey the rules.
Software - antivirus, spyware software,password.
Hardware - thumb scan, finger print.
Physical Control - ownself protection of the belonging such as using laptop lock
[ am not very sure what its been called act.. hihihi=)

above are the method used for the vital protection.

ENCRYPTION :

the READABLE text/plain change to unreadable text.

DECRYPTION :

change the UNREADABLE text to plain text.

TYPE OF ENCRYTION:

3 Chipping Step
counting three step forward of the alphabet to become new alphabet.
extra info !!
pioneer of 3 step chipping is Julies Ceasar.


Streganography
hidden word in one extra block of text.
can be break using software called GIF IT UP.
a combination of text and graphic, after being encrypt get the info.
extra info!!
using by AL QAEDA to crush the World Trade Centre.

Digital Drop Box
secret info in the draft email.

Network Security Notes

NETWORK SECURITY

1st level INFORMATION SECURITY = if hardcopy its been written P&C.
[private & confidental]

2nd level NETWORK SECURITY = unable to surf on some pages/access denied.


3rd level PC/DEVICE SECURITY = firewall, antivirus, ZIP folders, password.


NETWORK SECURITY can be ATTACK by 4 ways :-


INTERRUPTION = block the signal. receiver don't get the information that being send
via sender.


INTERSEPTION = view the vital/private information before its being send to
the receiver.


MODIFICATION = alter/twist the info to be wrongly understood for receiver.


FABRICATION = create/fabricate fake/independent information to the sender which
is the info never mean to be send/state for receiver.


SOCIAL ENGINEERING ATTACK = pretend to be someone else to take advantages or
to get an information. [ BEWARE !!! ]
