Cryptography and Network Security Forouzan Solution
Cryptography is the process of converting ordinary information, like plaintext, into unreadable unintelligible form. This refers to ciphertext and vice versa. Cryptography is used for protecting sensitive information from unauthorized access and for providing secure communication over the Internet.
Also, cryptography is a subject of study in Computer Science that involves the use of codes and ciphers. This is to protect information from unauthorized access and to ensure its authenticity. So, it is the foundation for building and maintaining secure computer networks.
Moreover, it ensures the privacy of communications over the Internet and other networks. This has many practical applications besides computer security. This includes military applications like communications, intelligence gathering, and code-breaking.
Below are some examples of cryptographic applications:
1. Digital signatures: They ensure that messages or files have not been tampered with during transmission over an insecure network such as the Internet.
2. Cryptographic hash functions: They are used to verify the integrity of messages or files. This by creating a digital fingerprint (hash value) unique to each message or file.
3. Encryption: It is used to protect sensitive data before it’s stored on a computer or sent over a network. This is by encoding it into an unreadable format called ciphertext. When necessary, the encrypted data can be decrypted (converted back into readable form).
4. Digital certificates: They provide users with assurance that they are communicating with a legitimate site on the Web. Also, verify that data has not been altered or corrupted since it was digitally signed. 5. SSL/TLS: It provides secure communication on the Web by using both encryption and authentication services.
Network Security Solution
You should have a monitoring system on your network. It will monitor the packets that come and go on the network. A Firewall is used to block undesired traffic from entering or leaving a private network. Firewalls protect against dangerous traffic, such as hackers who are trying to gain access to your network.
Also, an Intrusion Detection System (IDS) is an application that monitors networks or individual computers. This is to check for malicious activity or policy violations and produces reports. So, it alerts to warn administrators of potential problems.
The Virtual Private Network (VPN) is a private communication network over the Internet. It enables users to send and receive data across shared or public networks. Since this is as if their computing devices were directly connected to the private network.
