NETWORK SECURITY

NETWORK SECURITY

1. FIREWALL

   • A firewall is something that protects a computer or network from data with unauthorized access. If it has authorized access a door will open up.
   • This is very useful because if there is data that is trying to get in that is unwanted it will close the gaps and not let it in.

2. ENCRYPTION

   • This is used to scramble data that is being sent over any network. The only way this can be accessed is by having the key or knowing how to decrypt.
   • This can be useful to stop people trying to access information or something that we have sent.

3. PASSWORDS

   • This is what is needed to log in to your accounts and stop other people from accessing all that is your.

4. ENCRYPTION

   • This is used to scramble data being sent via a network so it can not be read without the "key".

5. USER ACCESS LEVELS

   • Different user of a network have different powers over it.

6. PHYSICAL SECURITY

   • It is used to keep the information on computers linked to it safe. It is where all the programs and logins are stored.
