It can detect and prevent malicious activities such as hacking attempts, malware infections, and denial-of-service attacks.
IPS works by analyzing network packets, comparing them to a databa...
- Q3. Firewall works at what layer?
- Ans.
Firewall works at the network layer.
Firewall operates at the network layer of the OSI model.
It filters and controls incoming and outgoing network traffic based on predetermined security rules.
Examples of firewalls include hardware firewalls, software firewalls, and cloud-based firewalls.
- Q4. Define firewall generations and their roles
- Ans.
Firewall generations refer to the evolution of firewall technology and their roles in network security.
First generation firewalls - packet filtering based on IP addresses and ports
Second generation firewalls - stateful inspection and improved security features
Third generation firewalls - application layer filtering and deep packet inspection
Fourth generation firewalls - next-generation firewalls with advanced threat pr...
- Q5. What is IP Spoofing?
- Ans.
IP Spoofing is a technique where an attacker impersonates another device by falsifying IP address in order to gain unauthorized access.
IP Spoofing involves manipulating the source IP address in a packet to deceive the recipient.
It is commonly used in DDoS attacks to hide the true source of the attack traffic.
Prevention methods include implementing ingress and egress filtering on network devices.
Examples of tools used f

Helps reduce network congestion by only sending data to the intended recipient
- Q2. OSI layer what happens and what do you do
- Ans.
In the OSI model, each layer has specific functions and responsibilities in the communication process.
The OSI model consists of 7 layers, each with its own specific functions and responsibilities.
Each layer communicates with the adjacent layers to ensure data is properly transmitted.
For example, in the OSI model, Layer 1 (Physical layer) deals with the physical connection between devices, while Layer 2 (Data Link layer
- Q3. What is the difference between a Router and a Switch
- Ans.
Routers operate at Layer 3 of the OSI model and make decisions based on IP addresses, while switches operate at Layer 2 and make decisions based on MAC addresses.
Routers operate at Layer 3 of the OSI model, while switches operate at Layer 2.
Routers make decisions based on IP addresses, while switches make decisions based on MAC addresses.
Routers connect different networks together, while switches connect devices within...
- Q4. VLAN what is happening
- Q5. What's the DNS ?
- Ans.
DNS stands for Domain Name System, which translates domain names to IP addresses.
DNS is like a phone book for the internet, translating human-readable domain names (like google.com) into IP addresses (like 172.217.3.206).
It helps users access websites by translating domain names into IP addresses that computers can understand.
DNS also helps with email delivery by translating domain names into IP addresses for mail serv...
