白皮书

阻止攻击者使用 DNS 对您 发起攻击

2019年4月17日 星期三
asset thumbnail

无论是什么行业、位于何地、规模如何或使用哪些产品,所有现代组织都需要使用域名系统 (DNS) 运营业务。DNS 是一种协 议,可将用户友好的域名(例如 www.paloaltonetworks.com)转换为机器可使用的 IP 地址 - 在本例中为 199.167.52.137。 如果没有 DNS,就需要我们亲自记住随机的数字字符串,而我们的大脑并不善于记忆大量信息且不遗忘。因此,DNS 成为 了全世界每个现代组织运营业务的基础。网络运营商无法阻截 DNS 流量,防火墙必须允许该流量通过。网络需要 DNS 才能 正常运行。
