What is Cyber Security?

Cyber security is the process of protection of hardware, software and data from the hackers. The primary purpose of implementing these cyber security techniques is to protect against different cyberattacks such as changing, accessing or destroying sensitive data.

2) What are The Fundamental Elements of Cyber Security?

Following are the main elements of cyber security:

Information security

End-user education

Operational security

Application security

Network security

Business continuity planning

3) What are The Main Advantages of Cyber Security?

Protects the business against unauthorized access including ransomware, social engineering, malware and phishing.

Protects end-users and improve the business continuity management

Improves stakeholder confidence

Provide adequate protection for both data as well as networks

Increase recovery time after any breach

4) What Do You Means By Cryptography?

Cryptography is the technique which is used to protect the confidential information from third parties called adversaries. It allows both sender and receiver of any message to read its details.


5) What is The Main Difference between IDS and IPS?

As the name indicates, IDS (Intrusion Detection System) detects the intrusions and an administrator prevent the intrusion carefully. Whereas in the IPS (Intrusion Prevention System), the system finds the intrusion and prevent it for better protection.

6) Explain The CIA Model?

CIA (Confidentiality, Integrity, and Availability) is a common model that is used to develop a security policy. It consists of the following concepts:

Confidentiality: Ensure the confidential and private data is accessed only by the authorized users

Integrity: It means the information is in the right format

Availability: Ensure the data and other required resources are available to those users who need them

7) Define The Firewall?

In simple words, the firewall is a network security device which is mainly designed to monitor incoming and outgoing traffic and blocks data based on the security rules. Firewalls are considered the best option to protect the network from worms, malware, viruses, remote access and content filtering.

8) What is Traceroute and How Can We Check It?

Traceroute is the network diagnostic tool which is used to track the real path of any data packet on an IP address from its source to destination. It reports the all IP addresses of routers and records the time taken for each hop. Traceroute is mostly used to check out the connection breaks to identify the point of failure.

Go to command prompt (cmd), write “tracert” and enter any domain name after a single space as you can view in the picture given below:

9) What is The Difference between HIDS and NIDS?

Parameter   HIDS   NIDS

Usage   Detect the intrusions         Used for the network

Monitoring It monitors suspicious system activities and traffic of any specific device.

It monitors the traffic of all devices on the network

Performance            Must be installed on every host   It can monitor multiple hosts at a time

10) What is SSL and Why We Need To Use It?

SSL (Secure Sockets Layer) is a technology used to create encrypted connections between web servers and web browsers. It is now compulsory for every website to be ranked on the first page of google and commonly used to protect online transactions, user’s data and digital payments.
