Question

1) What are firewalls and intrusion detection systems?

2)Why are encryption applications an important security tool?

3)What kind of budgeting does your job use? What are the pain points that management feels because of this? Where are you seeing the benefit, or the problems, that result, and would another budgeting model work better?

Answer 1

Solution 1 :

Firewall :

1. A firewall is a software or hardware which is used for securing the computer networks from any unauthorized access. Means, it verifies, checks and allows the entrance of the data packets into the networks in an effective manner.

2. A firewall works as a security guard for the network because it is useful for filtering and reducing the network-related risks by identifying malicious data packets.

Intrusion Detection System ( IDS ) :

1. An Intrusion Detection System ( IDS ) is a device or a software application or we can say that a useful tool for identifying the network spoofing attacks and suspicious activities so that the network could be easily protected.

2. IDS is useful for both types of networks ( single computer networks as well as large computer networks ).

3. Apart from this, it effectively identifies heuristics and patterns of the common computer network attacks so that it could protect the whole network from any further spoofing attacks.
