网络安全是一门基于计算的学科，涉及技术，人员，信息和流程，以保护计算机系统免受攻击。它涉及安全计算系统的创建，运行，分析和测试。网络安全专业人员知道如何保护网站，移动应用程序，操作系统，数据库，网络和嵌入式计算系统的安全。他们始终关注最新的计算机漏洞，帮助防止员工沦为社会工程攻击的受害者，与领导层协作以减轻和管理风险，监视系统以识别入侵者，并在成功攻击发生时做出有效响应。公司和组织聘用了渗透测试人员（也称为Red Team成员），以合乎道德的方式侵入系统来识别漏洞。数字取证调查员使用复杂的工具来追踪攻击者
Cybersecurity is a computing-based discipline involving technology, people, information, and processes to protect computing systems from adversaries. It involves the creation, operation, analysis, and testing of secure computing systems. Cybersecurity professionals know how to secure websites, mobile apps, operating systems, databases, networks, and embedded computing systems. They stay current on the latest computer vulnerabilities, help prevent employees from falling victim to social engineering attacks, collaborate with leadership to mitigate and manage risks, monitor systems to identify intruders, and respond effectively when successful attacks occur. Penetration testers, also known as Red Team members,are hired by companies and organizations to identify vulnerabilities by ethically hacking into systems. Digital forensics investigators use sophisticated tools to track down attackers and capture evidence that can be used in court.
