What does CANS mean in CYBER & SECURITY
Cryptology and Network Security (CANS) are two related but distinct areas of research. Cryptology involves the study of how to develop secure encryption and other methods for protecting data from unauthorized access. Network security is concerned with keeping networks and computers secure from attack by malicious attackers. Both disciplines have become increasingly important for protecting digital information, as well as individuals' personal information, in modern society. In this article, we will look at what each discipline entails, their differences, and why understanding them is so important

Essential Questions and Answers on Cryptology and Network Security in "COMPUTING»SECURITY"
What is Cryptology?
Cryptology is the practice and study of techniques for secure communication in the presence of third parties. It encompasses both cryptography, the use of mathematical techniques to provide security, and cryptanalysis which is the science studying methods to break cryptographic security systems.
What types of security does Cryptology provide?
Cryptology provides components for confidentiality, data integrity, authentication, access control and non-repudiation. These components ensure that transmitted messages are not intercepted by a third party or modified without authorization.
What is Network Security?
Network security involves protecting networks from unauthorized access, misuse, malfunction, modification, destruction or improper disclosure in order to assure the confidentiality, integrity and availability of network resources. This includes protection from both internal and external threats such as malware.
How can we protect our networks with Cryptology?
Technological measures such as encryption algorithms can be used to secure data transmission from interception. Firewalls can be put into place to limit access to trusted users. Access control measures such as passwords can also be implemented to secure sensitive information from unauthorized personnel.
Is Cryptology only used for computers?
No - it can also be used for other forms of communication such as radio and satellite transmissions that involve sending coded messages between sender and receiver devices.
What kind of encryption algorithms are commonly used in Cryptology?
Commonly used encryption algorithms include Data Encryption Standard (DES), Advanced Encryption Standard (AES), Rivest-Shamir-Adelman (RSA) algorithm and Blowfish algorithm. More recent algorithms include Elliptic Curve Cryptography and Quantum Key Distribution (QKD).
How does Network Security differ from Computer Security?
Computer security covers protection against malicious programs while network security covers prevention of access to a computer network by unauthorized users or processes such as malware or malicious “bots” as well as preventing unwanted traffic originating from outside sources entering the computer network system.
How do attackers seek to compromise networks protected by Cryptology?
Attackers may try to gain access through brute force attacks whereby they guess valid usernames/passwords combinations in attempts to gain entry into systems/networks or they may try vulnerability assessments whereby they look for weaknesses or vulnerabilities within a system/network which they can exploit. They may also try social engineering attacks where they manipulate people into revealing confidential information which will allow them access into systems/networks.
Are there different types of Network Security solutions available?
Yes – these range from basic measures such as using passwords and firewalls or more complex solutions like Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS). There are also technologies such as Virtual Private Networks (VPNs) which aim at making private networks more secure when accessing public networks.
