Cybersecurity refers to the protection of hardware, software, and data from attackers. The primary purpose of cyber security is to protect against cyberattacks like accessing, changing, or destroying sensitive information.
What are the elements of cybersecurity?
Major elements of cybersecurity are:
Business continuity planning.
What are the advantages of cyber security?
Benefits of cyber security are as follows:
It protects the business against ransomware, malware, social engineering, and phishing;
It protects end-users;
It gives good protection for both data as well as networks;
Increase recovery time after a breach;
Cybersecurity prevents unauthorized users.
What is hacking?
Hacking is a process of finding weakness in computer or private networks to exploit its weaknesses and gain access.
For example, using password cracking technique to gain access to a system.
Who are hackers?
A Hacker is a person who finds and exploits the weakness in computer systems, smartphones, tablets, or networks to gain access. Hackers are well experienced computer programmers with knowledge of computer security.
What is CIA?
Confidentiality, Integrity, and Availability (CIA) is a popular model which is designed to develop a security policy. CIA model consists of three concepts:
Confidentiality: Ensure the sensitive data is accessed only by an authorized user;
Integrity: Integrity means the information is in the right format;
Availability: Ensure the data and resources are available for users who need them.
What is a Firewall?
It is a security system designed for the network. A firewall is set on the boundaries of any system or network which monitors and controls network traffic. Firewalls are mostly used to protect the system or network from malware, worms, and viruses. Firewalls can also prevent content filtering and remote access.

What is a VPN?
VPN stands for Virtual Private Network. It is a network connection method for creating an encrypted and safe connection. This method protects data from interference, snooping, censorship.
What do you mean by penetration testing?
It is the process of checking exploitable vulnerabilities on the target. In web security, it is used to augment the web application firewall.

What is Data Encryption? Why it is important in network security?
Data encryption is a technique in which the sender converts the message into a code. It allows only authorized user to gain access.
