ISC2---CyberSecurity课程笔记---第四章：网络安全
让我们更详细地了解一下计算机网络和网络安全。在当今世界，互联网几乎连接了每个人和一切，这是通过网络实现的。虽然大多数人认为计算机网络是一个积极的，但犯罪分子经常使用互联网和网络协议本身，作为武器和工具来利用漏洞，出于这个原因，我们必须尽最大努力保护网络。我们将回顾网络的基本组成部分，网络的威胁和攻击，并学习如何保护它们免受攻击者的攻击。网络安全本身可以是网络安全中的专业职业;然而，所有信息安全专业人员都需要了解网络的运行方式和如何被利用，以更好地保护网络的安全。
ISC2---CyberSecurity课程笔记---最终章第五章：安全操作 Security Operations
Encryption我们在现代数字世界中采取的几乎每一个行动都涉及密码学。加密保护我们的个人和商业交易;数字签名的软件更新验证其创建者或供应商的真实性声明。数字签名的合同对各方都有约束力，通常通过电子邮件交换，而不必担心后来被发件人拒绝。ciphertext密码学用于保护信息，方法是将信息的含义或内容保密，并使无法解密（解锁）受保护信息的人无法理解。每个加密系统的目标都是将原始数据集（称为明文）转换为另一种难以理解的加密形式（称为密文）。
