Networking Security
Izhak Rubin · 2024
This chapter focuses on outlining methods for secure end-to-end message transfer across a network system. Security objectives for such transfers include: confidentiality; integrity; authenticity, and digital signature. A security system architecture implements means for assuring the effective and efficient functioning of a targeted system, in protecting data and networking operations even when the security system itself is under attack. Examples of common cybersecurity-oriented attacks include the following: phishing; malware; ransomware; and social engineering oriented attacks. A secure key exchange process is efficiently implemented by using a public-key encryption system. For the symmetric key cryptographic process to retain its strong measures of confidentiality and authentication, it is critical that the shared key is kept secret. Schemes are employed to preserve message confidentiality, integrity, and identity as it is transported across a network during a client–server session.
