CS707: Network Security
Network Security includes access control, virus, and antivirus software, application security, network statistics, network-related security types (endpoint, web, wireless), security walls, VPN encryption, and more. It is a set of rules and configurations designed to protect the integrity, confidentiality, and access of computer networks and data using both software and hardware technologies. Every organization, regardless of size, industry, or infrastructure, needs a level of network security solutions to be protected from the ever-growing threat of cyberbullying in the wild today.
Access control defines individuals or groups and devices that have access to network applications and systems thereby preventing unauthorized access and possible threats. Integration with Identity and Access Management (IAM) products can firmly identify the user and Role-based Access Control (RBAC) policies ensure that the individual and the device are authorized to access the assets.
A cyber threat or cybersecurity is a vicious act that seeks to damage data, steal data, or disrupt digital life in general. Cyber threats include computer viruses, data breaches, Denial of Service (DoS) attacks, and other attack vectors. A cyber threat is a function intended to jeopardize the security of an information system by altering the availability, integrity, or confidentiality of the system or information it contains. An online threatening environment is an online environment where online actors do the work of malicious online threats.
What Is a Network Attack?
A network attack is an attempt to gain unauthorized access to an organizational network, with the intent of stealing data or engaging in other malicious activity. There are two main types of network attacks:
Passive: Attackers gain access to the network and may monitor or steal sensitive information, but without making any changes to the data, they leave it all out.
Active: Attackers not only gain unauthorized access but also edit, delete, encrypt or damage the data.
Cryptography is a secure communication method that only allows the intended sender and recipient of a message to view its content. The name is derived from the Greek word Kryptos, meaning “hidden.” It is a way of protecting information and communication through coding so that only the intended information can be read and processed.
Types of Network Security Protections
Cryptography is closely related to cryptology guidelines and cryptanalysis. Includes techniques such as small dots, combining words and images, and other ways to hide information in storage or transportation. However, in today’s computer-centered world, cryptography is often associated with writing plain text (normal text, sometimes called plain text) into ciphertext (a process called encryption), and back again (known as encryption). The people who do this work are known as cryptographers.
