1:Explain about the cybersecurity?
AnswerIt refers to protection of the software, hardware as well as data from the attacks. The main purpose of this cybersecurity is for protecting from the cyberattack. The cyberattacks are just like access, change or destroy the sensitive information.
2:Can you explain about the Cryptography?
Answer :This technique is used to protect the information from the third parties. Generally, we call them as adversaries. It allows both the sender as well as receiver of the message to read the details.
3:Explain about the CIA:
Answer :CIA stands for the Confidentiality, Integrity as well as Availability. It is very popular modular. It is developed for the security policy. This model has three concepts. They are,
Confidentiality:
This ensures whether the secured data are accessed by the authorized users only.
Integrity:
It refers whether the information available is in the correct format.
Availability:
It ensures whether the data as well as resources are available. Especially for the required users.

4:Can you list the cybersecurity elements?
Answer :Following are the major cybersecurity elements. They are,
Application security.
Information security.
Operational security.
End-users education.
Network security.
Business continuity plane.
Application security.
Information security.
Operational security.
End-users education.
Network security.
Business continuity plane.
5:Can you state the difference between the IDS & IPS?
Answer :IDS generally detect the intrusion. The admins need to be very careful in preventing this intrusion. In IPS, system itself find intrusion as well as prevent them.
6:List the advantages of the cybersecurity?
Answer :Following are some of the advantage of the cybersecurity. They are,
This protects our business from malware, phishing, ransomware as well as social engineering.
This protects the end users.
This provides best protection for the data & networks.
This increases the time of recovery after the breach.
This prevents from the unauthorized users.

7:Can you explain about the data leakage?
Answer :It is unauthorized transferring the data to outside world. This occurs through optical media, USB, laptops as well as email.
8:Explain about the Firewall?
Answer :This security system is specially designed for networks. It will be set on boundaries of systems. In other word we can able to say that it is a network. This will monitor as well as control the traffic of the network. Mostly it is used for protecting systems & networks from the viruses, worms as well as malwares. Also, it prevents us from the content filtering as well as remote access.
9:Can you tell me about the Traceroute?
AnswerTraceroute is one of the tools. Path of the packet will be shown by this tool. This tool will list all points which is pass by the packet. Mostly this tool is used when packet can’t reach its destination. This will check about the connection breaks /stop / for identifying the failure.
10:Explain the SSL?
Answer :The full form of SSL is Secure Socket Layer. This technology will create the encrypted connection between the web server as well as web browser. The information which is in the online transactions as well as digital payment for the militance of the data privacy are protected by this.
11:State the difference between the NIDS and HIDS?
Answer :
Following are the difference between the NIDS and HIDS. They are,
Following are the difference between the NIDS and HIDS. They are,
| S: No | Criteria | NIDS | HIDS |
| 1 | Monitoring | suspicious activities of the system as well as traffic of the specific device are monitored by the NIDS. | Traffic of the devices on network are monitored by the HIDS. |
| 2 | Usage | Use for detecting intrusions. | Use for network. |
12:Can you tell me about the VPN?
Answer :Virtual private network is the full form of VPN. This is the method of network connection to create encrypted as well as safe connection. With the help of this, we can able to protect the data from the interference, censorship as well as snooping.
13:Can you able to tell me about the attack of brute force?
Answer :This method is known as trail & error method. Using this we can able to find the correct password / PIN. Generally, the hackers try again and again with all the combinations of the credentials. Most of the cases the attacks of the brute force are automated. In such cases software works automatically for logging in with the credentials.
14:List out the ways for preventing the attacks of the Brute force?
Answer :Generally, there are three ways for preventing these attacks. Following are the three ways of attacks.
Setting the length of the password.
Increase the complexity of the password.
Need to set the limit for the failures of the login.
Setting the length of the password.
Increase the complexity of the password.
Need to set the limit for the failures of the login.
15:Can you list out the different OSI models layers?
Answer :Following are the 7 different ways of OSI models. They are,
Physical.
Data link.
Network.
Transport.
Session.
Presentation.
Application.
Physical.
Data link.
Network.
Transport.
Session.
Presentation.
Application.
16:Explain about the port scanning?
Answer :This is a technique. This is used to identify the open ports & services which are available on the specific host. Generally, the hackers use this to find all the information for the malicious purposes.
17:Explain about the MITM attack?
Answer :This is one type of the attack. Using this attack, the hackers can able to communicate between the 2 persons. Very important intention of the MITM is for accessing the information which is very confidential.
18:Can you tell me about the hackers who named as the black hat?
Answer :This kind of hackers have very good knowledge in all the breach of the network security. Generally, they create malware for their own gain. Usually, they break the network security for modifying, stealing or destroying the data. So, the authorized users are not able to use the network.
19:Can you tell me about the hackers who named as the Grey hat?
Answer :They are generally known as the computer hackers. In sometimes they violate the ethical standards. But they don’t have the malicious intent.
20:Can you tell me about the hackers who named as the White hat?
Answer :They are security specialist. They will easily penetrate the testing. They are responsible for the protection of the company’s information system.
21:Can you explain about the BIOS config for resetting the password protection?
Answer :Generally, we have many ways for resetting the BIOS password. They are,
Using MS-DOS.
Using the motherboard jumper.
Using software.
Removing the CMOS battery.

Using the motherboard jumper.
Using software.
Removing the CMOS battery.
22:Can you tell me the importance of the DNS monitoring?
Answer :We can find that the Yong domains can be easily affected by the malicious software. For identifying the malware, we need to use the tool of DNS monitoring.
23:Can you tell me about the botnet?
Answer :This is the number of the devices which are connected on the internet just like mobiles, servers, IoT as well as PCs. These are infected as well as controlled by the malware.
24:Explain about the ARP?
Answer :This protocol is used to find the MAC address which is associated with the IPv4. Generally, this protocol works as the interface between OSI networks as well as OSI link.
25:Explain about the WAF?
Answer :It is used for protecting the apps just by filtering as well as monitoring both the incoming as well as outgoing traffics. Especially between web apps as well as internet.
