   • Cryptography and Network Security Principles

     In present day scenario security of the system is the sole priority of any organisation. The main aim of any organisation is to protect their data from attackers. In cryptography, attacks are of two types such as Passive attacks and Active attacks. 

     Passive attacks are those that retrieve information from the system without affecting the system resources while active attacks are those that retrieve system information and make changes to the system resources and their operations.

     The book Cryptography Engineering by Ferguson, Schneier, and Kohno might be something that would get you a decent way down the road to understanding the topics you listed. I read the first version of this book (Practical Cryptography) and found it to be quite good. For example, I thought the descriptions of public key/private key cryptography to be reasonably straightforward to understand.

     It might not explicitly describe the specific terms in all cases that you are asking about. For example, I just looked in the index of my copy of Practical Cryptography and do not see the terms "keystore" and "truststore", but the first google hit I clicked on for those provided a definition in language I understood (largely because I read the book).

     I also own Applied Cryptography mentioned by Aidan Cully, and I think it is also a very good book and certainly worth owning. However I tend to think of it more as a reference book (although somewhat dated - the copyright is 1996). In terms of real-word advice, though, I think the original title of the newer book Practical Cryptography was right on. The book seems, well, practical.

   • Network Time Protocol (NTP) Security and Authentication

     In the powerful scene of PC organizations, where accuracy is foremost, the Network Time Protocol (NTP) assumes an essential part in coordinating a consistent worldly dance among gadgets. As the foundation of time synchronization, NTP guarantees that divergent frameworks can walk as one, working with strong and proficient tasks across an organization. In any case, this fundamental capability of timekeeping stretches out past simple coordination; it supports basic parts of network protection, framework logging, and confirmation.

     Precise timekeeping fills in as the bedrock for sequential requests in framework logs, supporting investigating, scientific examination, and consistency adherence. In the domain of online protection, timestamp precision is crucial for distinguishing and answering security occurrences. Composed time is likewise vital for confirmation conventions, guaranteeing that protected correspondence between elements is grounded in a common transient reference.

     However, amid the dependence on NTP for worldly requests, the weakness of malevolent assaults turns into an approaching concern. The potential for foes to control time synchronization presents a huge gamble, equipped for sabotaging the honesty and security of different organization capabilities. This is where the emphasis on NTP security and confirmation becomes basic....

   • Difference Between Network Security and Network Administration

     In the world of information technology, there are two important and distinct roles that are often confused: network security and network administration. While these two jobs may be closely related, they require different sets of skills and responsibilities. It’s significant to understand the differences between network security and network administration in order to determine which role is best suited for your particular organization.

      

     Network Security

     Network security is the practice of protecting a network from malicious attacks and unauthorized access. This involves implementing measures such as firewalls, antivirus software, intrusion detection systems, and encryption algorithms to protect data, systems, and networks from unauthorized access. Network security professionals are responsible for developing and implementing policies and procedures that protect the integrity and confidentiality of the network. Network security professionals must have a thorough understanding of security protocols and technologies, as well as the ability to identify and respond to potential vulnerabilities and threats. They must also be familiar with common security tools and technologies, such as firewalls, antivirus software, and intrusion detection systems.

     Advantages of Network Security:

   • Confidentiality: The degree of confidentiality determines the secrecy of the information. The principle specifies that only the sender and receiver will be able to access the information shared between them.
   • Authentication: Authentication is the mechanism to identify the user or system or the entity. It ensures the identity of the person trying to access the information.
   • Integrity: Integrity gives the assurance that the information received is exact and accurate. If the content of the message is changed after the sender sends it but before reaching the intended receiver, then it is said that the integrity of the message is lost.
   • Non-Repudiation: Non-repudiation is a mechanism that prevents the denial of the message content sent through a network. In some cases the sender sends the message and later denies it.

   How secure is a cryptographic system?

   • Remember, as we said, any cryptographic system involves both an algorithm and a key. Kerckhoffs believed that “a cryptographic system should be secure even if everything about the system, except the key, is public knowledge.” Now, these were the days when cryptography had almost entirely military applications.
