Description The Network Security Essentials course starts with introducing the common risks to the organization network, including viruses, worms, Trojans, OS vulnerabilities, DoS/DDoS and more. We talk about the basics of data deletion, duplication and modification risks, OS and applications vulnerabilities, eavesdropping and data forgery, disguised Identities and others. We continue with describing protection mechanisms, including authentication, access control, confidentiality, integrity and others, and how they are used to protect the organization data. Follows the principles part we talk about the purpose and operation principles of firewalls including packet filtering and statefull inspection and VPNs, including the operation of Site-to-Site and Client-to-Site connectivity. We continue with common security protocols, authentication and encryption principles, describing the principles of authentication, from the basic username and password access to challenge-response mechanisms and advanced token and biometrics methods. In the protocols area we talk about basic cryptography, symmetric and asymmetric encryption, Di­e-Hellman algorithm and key-exchange mechanisms, RSA, PKI, KDCs, Certificates and digital signatures. The course is in introduction level, describing the operating principles of network security, preparing the participant to the advanced courses in this section.
