CCNA vs. CompTIA Security+ 认证

CCNA vs. CompTIA Security+ 认证

Aug 12, 2025

在当今竞争激烈的 IT 领域,认证是宝贵的资质证明:它不仅能验证你的技术能力,还能提升职业发展前景。无论你是刚进入行业,还是希望进一步进阶,获得合适的认证都能让你从竞争中脱颖而出,并为更好的工作机会与发展通道打开大门。

最受追捧的 IT 认证之一是 CompTIA Security+ 以及思科认证网络助理(Cisco Certified Network Associate,CCNA)。这两项认证在业界都备受认可,但它们面向的职业路径不同:Security+ 着重网络安全领域的基础知识与技能,而 CCNA 则强调网络概念以及思科相关技术。

本文提供信息,帮助你判断 CCNA 还是 Security+ 是否更适合你的职业发展。它将对两者的侧重点、工作机会、难度等级以及理想人选进行比较,从而根据你的目标引导你做出最佳选择。

CCNA 和 CompTIA Security+:概览

CCNA

Cisco Certified Network Associate 是思科 Systems 提供的入门级网络认证。思科是网络硬件、软件、电信设备以及网络安全解决方案领域的领先供应商。思科成立于 1984 年,亦以提供在业界广泛认可的 IT 认证而闻名。

CCNA 面向使用 Cisco 技术的网络工程师和 IT 专业人士而设计。它验证你对网络基础知识的掌握程度,并涵盖安全、自动化和可编程性等方面。该认证包括:

  • 网络基础
  • IP 地址与子网划分
  • 路由与交换概念
  • 安全基础
  • 自动化与可编程性

CCNA 非常适合:

  • 有志成为网络工程师、系统管理员和 IT 支持技术人员的人
  • 希望专攻 Cisco 网络的 IT 专业人员
  • 具备一定 IT 知识并有动手实践经验的个人

CompTIA Security+

CompTIA Security+ 认证由 CompTIA(Computing Technology Industry Association,计算技术产业协会)颁发——该组织是于 1982 年成立、在全球范围内广受认可的非营利行业协会。CompTIA 以开发 IT 认证而闻名,这些认证能够验证多个领域的技术能力。

Security+ 于 2002 年推出,作为面向入门级网络安全从业人员的标准化、厂商中立认证。多年来,它不断发展,以紧跟最新的安全趋势、技术和最佳实践。它也可作为通往 CISSP、CEH 或 GSEC 等更高级别认证的垫脚石。Security+ 已获得 ANSI 认证,并符合 ISO 17024 标准,因此在全球范围内(包括美国国防部(DoD))得到了雇主的广泛认可。

CompTIA Security+ 认证在以下主要领域建立基础的网络安全技能:

  • 威胁、攻击和漏洞
  • 网络安全与架构
  • 身份与访问管理(IAM)
  • 风险管理与合规
  • 密码学与 PKI

Security+ 最适合想进入网络安全领域的个人,例如:

  • 开启网络安全职业生涯的个人
  • 希望拓展到网络安全领域的帮助台技术人员、网络管理员、系统管理员以及其他 IT 专业人士
  • 由于 Security+ 符合 DoD 8570 合规要求,正在寻求从事网络安全岗位的政府与军队人员

CCNA vs Security+:证书对比

这两种证书之间的主要差异如下:

  • Security+ 侧重于网络安全原则,而 CCNA 强调网络概念。
  • Security+ 覆盖通用 IT 安全,而 CCNA 包含思科特定的网络技术。
  • CCNA 具有基于模拟的题目,因此比 Security+ 更偏实操。

根据职业目标选择合适的认证

在考虑 Security+ 与 CCNA 时,请思考以下几点。

Choose CCNA if:

Choose Security+ if:

You want a career in networking, working with routers, switches and network infrastructure.

You are interested in cybersecurity, risk management and security policies.

You are aiming for a role like Network Administrator, Network Engineer or IT Support Specialist.

You are aiming for a role like Security Analyst, SOC Analyst, IT Security Specialist or Compliance Officer.

You are interested in hands-on technical work with Cisco devices and networking concepts.

You need a certification that meets US Department of Defense (DoD) 8570 requirements.

You plan to specialize in advanced networking (e.g., CCNP, CCIE) later.

You plan to pursue more advanced security certifications (e.g., CISSP, CEH, CySA+, CASP+).


You want to work in areas like telecommunications, cloud networking, enterprise IT or service providers.

You want to work in security-focused sectors like government, finance or healthcare.

两种认证都很有益的场景

在以下情况下,同时拥有 CCNA 和 Security+ 可能非常有价值:

  • IT 通才与系统管理员 — 如果你同时管理网络和安全,CCNA 有助于提升网络方面的知识,而 Security+ 则确保你理解网络威胁以及安全最佳实践。
  • 网络安全工程师 — 如果你想专注于网络安全(防火墙、入侵检测、VPN),CCNA 和 Security+ 都能为你提供扎实的基础。
  • 具备网络知识的网络安全专业人士 — 许多安全威胁会利用网络漏洞。具备 CCNA 级别知识的 SOC 分析师或网络安全工程师,能够更好地保护基础设施。
  • 就业市场竞争力 — 雇主往往更倾向于选择同时具备网络与安全专业能力的候选人,尤其是网络安全分析师、网络安全工程师或 IT 管理员等岗位。

结论

选择合适的认证是塑造 IT 职业生涯的关键一步。CCNA 和 Security+ 都能提供宝贵的知识,但它们面向不同的职业发展路径:

  • CCNA 最适合那些希望从事以配置和管理网络基础设施为重点的网络相关岗位的人。
  • Security+ 非常适合对网络安全感兴趣的人,因为它涵盖安全原则、风险管理和合规要求。对于刚进入 IT 领域、希望获得入门级认证的个人来说,它也是一个不错的选择。
  • 在某些情况下,同时获得两项认证可能会显著提升就业前景,尤其是涉及网络安全的岗位。

归根结底,正确的选择取决于你的兴趣和职业目标。花点时间评估自己的愿景,考虑你目前的技能,并做出一项符合你抱负的明智决定。

常见问题

CCNA 比 Security+ 更难吗?

由于 CCNA 侧重动手型网络(hands-on networking)并采用基于实验室的考试形式,通常被认为比 Security+ 更具技术挑战性。CCNA 需要对路由、交换以及网络协议有深入理解,同时还需要在思科(Cisco)设备上进行实际配置的技能。考试包含仿真题:你必须配置真实的网络设备。Security+ 则以客观题为主,在基础层面涵盖更广泛的网络安全概念,因此对初学者而言更容易上手。CCNA 通常需要 3-6 个月的高强度学习,并配合动手实验室实践;而 Security+ 则可在专注学习 2-3 个月内完成。尽管如此,难度取决于你的背景:网络从业者往往觉得 CCNA 更直观,而拥有一般 IT 经验的人可能会觉得 Security+ 的概念更容易掌握。两种认证都需要投入,但 CCNA 对技术深度和实践能力的要求更高。

做网络安全(cybersecurity)相关的学习时,应该先考 CCNA 还是先考 Security+?

在网络安全(cybersecurity)职业发展方面,通常应先考取 Security+。原因是它提供你在任何专业方向中都需要的安全基础知识。Security+ 涵盖风险管理、密码学(cryptography)以及安全协议(security protocols)等关键概念,这些内容适用于所有网络安全领域。它还是一项获得 DoD 8570 批准的认证,可让你立即进入政府部门与承包商岗位。若你明确瞄准网络安全相关岗位,CCNA 也很有价值;但现代网络安全越来越强调身份(identity),而非传统的边界(perimeter)。先从 Security+ 建立安全基础,然后如果你想专注于网络安全,再补充学习 CCNA。该做法与行业向“基于身份的安全模型”的转变相一致:在这种模式下,对用户访问与数据保护的理解,比对传统网络边界的关注更重要。 Data security that starts with identity makes Security+ knowledge more immediately applicable to current threat landscapes.

做网络安全(cybersecurity)需要 CCNA 吗?

大多数网络安全岗位并不需要 CCNA,但在一些特定方向(如网络安全、事件响应(incident response)和安全架构(security architecture))中,具备网络相关知识会有所帮助。现代网络安全的关注点,较传统的网络边界防御,更倾向于身份管理、云安全和数据保护。身份与访问管理、合规、安全分析以及漏洞管理等岗位通常不要求深入的网络专业知识。不过,CCNA 能为理解攻击如何在网络中传播、以及安全控制如何在不同层级发挥作用提供宝贵的背景信息。如果你瞄准安全工程师、网络安全分析师,或 SOC 分析师等岗位(负责调查基于网络的威胁),CCNA 的知识就会更有相关性。对大多数初级网络安全岗位而言,Security+ 能提供更好的基础知识。与其停留在传统网络概念,不如把重点放在与当前威胁路径(threat vectors)相匹配的身份安全、云平台和数据保护能力上。

CCNA 能帮助网络安全吗?

CCNA 绝对能帮助网络安全:它提供了支持安全实施和威胁分析所必需的基础网络知识。理解网络如何运作,可以帮助你配置安全设备,在网络流量中分析潜在威胁,并实施恰当的网络分段。CCNA 涵盖访问控制列表(ACL)、VPN 以及网络安全基础,这些内容都能直接应用到网络安全相关岗位中。许多安全工具与概念都建立在网络原理之上:防火墙、入侵检测系统(IDS)以及网络监控都需要网络知识才能有效落地。然而,请记住,网络安全已经发展到不仅仅是“边界防护”。现代威胁会针对身份以及云环境,而这些场景中传统网络概念的适用性相对较弱。CCNA 在网络安全岗位中最有帮助,但也不要忽视以身份为中心的安全技能——因为它们能帮助你理解如今攻击者实际是如何运作的。最强的网络安全专业人员会将网络知识与身份安全专长结合起来。

从事网络安全职业时,CCNA 值得考吗?

如果你的目标是网络安全方向的专业化,那么考取 CCNA 具有一定价值;但对大多数现代网络安全岗位而言,它并非必需。该认证提供扎实的基础网络知识,能够支持安全实施,不过网络安全的重点已经转向身份(identity)为基础的威胁以及云环境。CCNA 对网络安全工程师、调查网络事件的 SOC 分析师,或负责设计网络控制措施的安全架构师等岗位很有帮助。与此同时,如果你从事的是身份与访问管理、合规或数据安全相关工作,其他认证往往能带来更高的投资回报。请仔细考虑你的职业目标:如果你希望专注网络安全,或进入需要同时具备网络与安全技能的组织,那么 CCNA 值得追求。对于通用的网络安全职业,建议把重点放在 Security+、云安全认证,或身份管理领域的专门证书上。关键在于理解:现代数据安全始于身份,因此与传统网络知识相比,身份导向的技能往往更有价值。
