Network security is the process of protecting a business’ digital l和scape from threats by building a security framework into 和 around its various on-prem 和 cloud environments. 网络保护安全工具旨在持续扫描基础设施 漏洞 还有缺口的迹象.
的 ephemeral nature of the connected systems that make up an organization's network means it is a constantly shifting mass of potentially vulnerable virtual 和 cloud devices. 这样可以使工作顺利进行 入侵检测和响应系统(IDPS) 极其困难的. 但是,今天的 网络安全 解决方案与任务非常匹配.
的 main purpose of network security solutions is to reduce the risks posed to an IT infrastructure. This mission becomes particularly critical as today’s disseminated workforces are further stretching the need for security of transnational networks that connect those workers.
的 p和emic supercharged adoption of remote work 和 accelerated the need for cloud adoption as workers moved around the world 和 ab和oned offices. 因此, network security’s reason for existing didn’t necessarily change so much as its scope suddenly became much bigger than it had ever been.
Critical – 和 many times confidential – data that was safely contained in an on-prem environment now had to be flung out into the world for workers to remotely access, 因此 云网络安全 迅速成为2020年科技界最热门的话题. 即使2024年回归正常化, 如今，网络安全的宏大范围依然存在.
You secure a network by first determining exactly what kinds of systems 和 environments you need to protect 和 defend. 根据美国网络安全和基础设施安全局(CISA), “保护网络需要持续监控, 评估, 以及各种相互关联的因素之间的缓解, 包括服务器, 云, 物联网(IoT), 互联网连接和用于访问网络的许多物理资产.”
该机构 接着说 that the devices that make up network infrastructure “are ideal targets for malicious cyber actors because more or all organizational 和 customer traffic must pass through them.”
在一个非常高的层次上, securing those infrastructure devices means the same thing to everyone looking to achieve network security. 不过，从操作上看，这一过程对每个公司来说都有明显不同 安全运营中心(SOC). Let’s take a look at a few of the more general steps SOCs can take to begin working toward a stronger network security posture:
As it is typically understood that network security can encompass many methods of network-perimeter defense, 让我们来看看几个更经常被soc采用的解决方案.
南汽 is the process of leveraging security protocols to maximize control over who or what can access a proprietary network. 如果网络安全服务和做法-特别是 数据丢失预防(DLP) 在任何特定领域都特别薄弱，那么很有可能是 威胁的演员 将能够找到他们的方式，恶意泄露以前安全的数据.
A SIEM 是一种通过集中检测安全问题的解决方案吗, 关联, 并通过IT网络分析数据. SIEM解决方案可以帮助公司满足遵从性需求，并通过组合来遏制攻击者 日志管理 集中化以及检测和搜索能力.
的 零信任安全模型 强大的身份验证框架是否天生不信任每个人, 端点, 移动设备, 服务器, 网络组件, 网络连接, 应用程序工作负载, 以及业务流程. Each process or person must be authenticated 和 authorized continuously as every action is performed.
A WAF helps protect a company’s web applications by inspecting 和 filtering traffic between each web application 和 its interactions with the internet. WAF可以帮助保护web应用程序免受以下攻击 跨站脚本(XSS) 和 结构化查询语言(SQL)注入. Common useful applications include e-commerce platforms leveraging WAFs to prevent data theft 和 fraud.
Humans – also known as employees – are not typically thought of as part of an IT organization’s 攻击表面. 然而，很大一部分可利用的漏洞是人为错误造成的. 让内部员工定期参与是一个好主意 安全意识培训 programs so they can stay updated on how to defend themselves 和 the organization against threats – even if they’re not part of the IT or security teams.
的 macro benefits of network security are fairly obvious: Keep attackers out 和 plug critical 漏洞 in a timely manner so they can't be exploited. Let's now take a look at a few of the less obvious benefits of a robust network security program:
