Security Research Activity: Network Security Common Tools & Techniques.
For each of the common tools:
Provide description:
DMZ (Demilitarization Zone): is a physical subnet that separates an internal LAN from unauthorized/ untrusted network, usually on the internet.
NAT (Network Address Translation): is the process where a network device assigns a public address to a computer inside a private network.
FWs (Firewalls): is a software that used to maintain the security of a private network. It control and monitor data that can flow into or out of the network.
Discuss its purpose.
DMZ: Allow access to resources from untrusted network while keeping the private network secure.
NAT: Is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes.
FWs: Can block unauthorized access by looking for suspicious words, domain names or IP addresses.
Give the advantages (2) and disadvantages (2).
DMZ:
Advantages:
Disadvantages:
NAT:
Advantages:
FWs:
Advantages:
Disadvantages:
Explain why organizations need to implement it.
Organization need to implement it because it can helps they organization from being hacked as well as hiding they IP address. if the worker decided to go to unprotected website for they work research/
Explain what will happens if it is not configured/ set up properly?
If DMZ, NAT and FWs are not set up properly the tools will not work properly as it should be. Such as the tools will run slowly or it will not prevent the hacker from hacking the data.

DMZ:
Advantages:
- Increase the security of the LAN.
- Do not offer any easy route. Therefore, it will be hard for hacker to hack.
Disadvantages:
- It is difficult to use because how complicated the set up is..(?)
- Access to the public servers is also much more restricted when it is isolated in a DMZ.
NAT:
Advantages:
- Provide additional layer of security by making the original source and destination addresses hidden.
- Provide increase flexibility when connecting to the public internet.
Disadvantages:
- Cause loss of end-device to end-device IP trace ability.
- Some technologies and network application will not function as expected in a NAT configured network.
FWs:
Advantages:
- Network Flexibility.
- Network Isolation.
Disadvantages:
- No Malware Protection.
- Operational Complex.
