A next-generation firewall (NGFW)
A next-generation firewall (NGFW) is a device that offers additional capabilities beyond traditional firewall functionality. Traditional firewalls may offer stateful packet inspection while a NGFW may provide integrated IDS/IPS functionality, for example.
The ability of a single device to perform multiple functions can be cost effective and may not require additional in-house expertise to support the technology. A drawback of using an NGFW is that it could become a single point of failure.
Assume you are in charge of deciding which types of firewalls to acquire and implement for an organization.
Answer the following question(s):
Would you choose an NGFW for a small business? Why or why not?
Would you choose an NGFW for a large organization? Why or why not?
Sample Answer
Whether to choose an NGFW for a small business or a large organization depends on a number of factors, including the size and complexity of the organization’s network, the organization’s security requirements, and the organization’s budget.
Here are some of the factors to consider when deciding whether to choose an NGFW:
- The size and complexity of the organization’s network: A small business with a simple network may not need the additional features and functionality of an NGFW. However, a large organization with a complex network may benefit from the additional features and functionality of an NGFW.
- The organization’s security requirements: An organization with high security requirements may need the additional features and functionality of an NGFW. For example, an organization that stores sensitive data may need an NGFW that can provide intrusion detection and prevention (IDS/IPS) functionality.
