An explicit Deny in any applicable policy (SCP, resource-based policy, permissions boundary, session policy, or identity-based policy) always overrides any explicit Allow. | | `basic` | What is the architectural difference between an IAM Identity-Based Policy and a Resource-Based Policy? | Identity-based policies attach to IAM users, groups, or roles to define what actions that principal can perform. Resource-based policies attach directly to a resource (such as an S3 bucket, SQS queue, or KMS key) and include a Principal element specifying who can access it. | | `intermediate` | How many IP addresses does AWS reserve in every VPC subnet CIDR block, and what are those five addresses used for? | AWS reserves 5 IP addresses in every subnet (first 4 and last 1). For example, in 10.0.0.0/24: .0 is the network address, .1 is reserved for the VPC router, .2 is reserved for the AWS DNS server, .3 is reserved for future use, and .255 is the network broadcast address. | | `intermediate` | Compare Security Groups and Network Access Control Lists (NACLs) in Amazon VPC. | Security Groups operate at the ENI/instance level, are stateful (return traffic is automatically allowed regardless of outbound rules), and support Allow rules only. NACLs operate at the subnet boundary, are stateless (both inbound and outbound return traffic on ephemeral ports must be explicitly permitted), and support numbered Allow and Deny rules evaluated in order. | | `advanced` | How do a process and a thread differ in a typical operating system? | A process is a resource and protection container with its own virtual address space. Threads within it share that address space and resources such as open files, but each has its own execution state, including registers, program counter and stack. Separate processes can explicitly share memory. | | `advanced` | What state is saved and restored during a CPU context switch? | The operating system preserves the outgoing task’s execution state, such as registers, program counter and stack pointer, and restores the incoming task’s state. Address-space state is changed when needed; switching between threads of one process need not change the page-table root. Exact saved state depends on the architecture and implementation. | ## 4. 8周间隔重复学习计划表 - **第 1–2 周：打牢基础（`basic`）**: 完成基础阶段卡组（每天 30–32 张新卡）。重点训练核心定义与基础概念的快速识别，每天坚持 15–20 分钟完成到期复习队列。 - **第 3–5 周：核心应用（`intermediate`）**: 在保持基础卡组每日间隔复习的同时，引入中级卡组（每天 20 张新卡）。翻卡前先口头或书面组织完整答案。 - **第 6–7 周：进阶精通与重难点突破（`advanced`）**: 过渡到高级卡组（每天 15 张新卡）。采用穿插练习法（Interleaving）混合基础、中级与高级卡片，在模拟考场条件下强化辨析能力。 - **第 8 周：巩固冲刺与自测**: 暂停学习新卡 7 天；清空 flashcards.world 上的所有待复习队列，并针对错满 2 次以上的顽固错卡进行专项重测。 ## 5. 常见学习误区及规避方法 - **不经思考直接翻看答案**：在翻转卡片*之前*，务必先在脑海中（或大声说出）组织好你的准确答案。 - **考前一晚突击死记 500 张卡**：间隔重复依赖睡眠期间的记忆巩固。每天坚持 20–30 分钟远胜过周末一次 4 小时的突击。 - **忽略语境与解析**：认真阅读每张卡片背面的完整例句或分析说明，理解概念在真实场景与考题中的运用。 - **跳过难度梯度**：在进入 `advanced` 高级卡组之前，先确保 `basic` 基础卡组的正确率达到 90% 以上。 ## 6. 常见问题解答（FAQ） ### 学习 网络安全与信息安全 每天应该刷多少张闪卡？ 为了实现可持续的长期记忆留存，建议每天学习 **20 至 32 张新卡**（1 个精选卡组）外加当日到期的复习队列（总计约 15–25 分钟）。 ### 在 flashcards.world 上应该从哪个难度的 网络安全与信息安全 卡组开始？ 建议先从**基础阶段（`basic`）**开始，检验对核心术语的掌握程度；当首轮正确率达到 85% 以上后，再进入**中级阶段（`intermediate`）**。 ### 我可以在手机和电脑上同步学习 网络安全与信息安全 闪卡吗？ 可以——本指南链接的所有卡组均可在 [flashcards.world](https://flashcards.world) 上通过手机浏览器和电脑端直接免费学习。 --- **[在 flashcards.world 上浏览全部 网络安全与信息安全 闪卡卡组 →](https://flashcards.world/flashcards/?q=Cybersecurity&back_lng=en)** ## Curated Flashcard Decks & Practice Sets - **Cloud Security: AWS IAM, Organizations, KMS, Encryption & Threat Detection**: [Interactive Deck](https://flashcards.world/flashcards/sets/a8c4bd4d-e524-42c2-a23d-619aac70f62d/) | [Markdown (.md)](https://flashcards.world/flashcards/sets/a8c4bd4d-e524-42c2-a23d-619aac70f62d.md) - **Network Security: Amazon VPC, NACLs, PrivateLink, VPN, CloudFront & Network Firewall**: [Interactive Deck](https://flashcards.world/flashcards/sets/17513362-f262-4846-aeb9-47ca26136ac5/) | [Markdown (.md)](https://flashcards.world/flashcards/sets/17513362-f262-4846-aeb9-47ca26136ac5.md) - **Operating Systems, Networking Protocols & Distributed Systems**: [Interactive Deck](https://flashcards.world/flashcards/sets/2268d201-52f1-442a-a1bf-83b3bedd56f8/) | [Markdown (.md)](https://flashcards.world/flashcards/sets/2268d201-52f1-442a-a1bf-83b3bedd56f8.md)
