Network security is a set of technologies that protects the usability and integrity of a company’s infrastructure by preventing entry or proliferation within a network of a wide variety of potential threats. For example, an anti-virus system.
Network security is established with authentication commonly with a username as a password. This is one-factor authentication. In two-factor authentication, something that the user already has like a phone number or any security pin is also used. And in three-factor authentication, a fingerprint or retinal scan of the user is also used.
What Risks Does Our Network Need To Be Secured?
Networks are prone to attacks from very harmful sources. These attacks include- Network Wiretapping, Passive Port scanner, Idle scan, Encryption, Traffic analysis, Virus, Eavesdropping, Data modification, Rajdhani Open, Denial-of-service attack, Active Port scanner, DNS spoofing, Man in the middle, ARP poisoning, VLAN hopping, Smurf attack, Buffer overflow, Heap overflow, Format string attack, SQL injection, Phishing, Cross-site scripting, Cross-site request forgery, or Cyber-attack.
What Is Cryptography?
Cryptography refers to the science and art of transforming messages to make them secure and immune to attacks. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it.
Thus preventing unauthorized access to information. Cryptography uses mathematical techniques to convert messages so that they become hard to decode.
Importance Of Cryptography In Network Security
When asking what is the importance of Cryptography, we can firstly see that the confidentiality of information is protected by cryptography’s special keys and algorithms.
This confidentiality of cryptography methods conveys that only the people with the provided special key and permission have access to the data and information that is transmitted.
The importance of Cryptography remains to protect data and users, ensure confidentiality, and prevent cyber criminals from intercepting sensitive corporate information.
Cryptography works with mathematical concepts formulating algorithms that are used for cryptographic key generation, digital signing, verification to protect data privacy, web browsing on the internet, and to protect confidential transactions such as credit card and debit card transactions.
- Privacy and Confidentiality to Individuals and organizations to protect their privacy and keep their conversations and data confidential.
- A common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted.
- Cryptography also secures browsing, such as with virtual private networks (VPNs), which use encrypted tunnels, asymmetric encryption, and public and private shared keys.
- Cryptography ensures information is not altered while in storage or during transit between the sender and the intended recipient. Hence proving the integrity of the information sent and received.
- Cryptography confirms accountability and responsibility from the sender of a message, which means they cannot later deny their intentions when they created or transmitted information.
- In email nonrepudiation, email tracking makes sure the sender cannot deny sending a message and a recipient cannot deny receiving it.
- Cryptography provides authentication at various levels to completely secure the information and prevent any breach.
