Slide 21 — Emerging Topics & Advanced Concepts
Cloud computing introduces shared responsibility models between providers (e.g., AWS, Azure) and clients.
Perimeter security aims to secure data as it travels across local networks and the internet.
Uses a mathematically linked pair: a public key and a private key.
Created by encrypting a message hash with a private key. This provides authentication, data integrity, and non-repudiation (the sender cannot deny sending the message). 🌐 Network and Perimeter Security computer security principles and practice 4th edition ppt
Symmetric vs. Asymmetric encryption, Hash functions, and Digital Signatures. User Authentication
Assures that information and programs are changed only in a specified and authorized manner.
The slides go beyond basic threats, covering sophisticated strategies like:
Updated standards reflecting the deprecation of older algorithms (like SHA-1) and emphasizing SHA-3 and modern AES implementations. Slide 21 — Emerging Topics & Advanced Concepts
Ensuring unauthorized individuals cannot access data.
To help me tailor this academic information further, please tell me:
Security professionals often have administrative access to sensitive user data. Adhering to professional codes of conduct—such as those published by the , IEEE , or ISC² —ensures privacy is protected, conflicts of interest are avoided, and systems are managed with integrity.
Assures that private or confidential information is not made available or disclosed to unauthorized individuals. Created by encrypting a message hash with a private key
If your course requires those, you may need to supplement the 4th edition PPTs with white papers or a newer edition's chapter slides.
