嵌入式Linux

嵌入式 Linux是以Linux为基础的嵌入式操作系统，被广泛地使用在移动电话、个人数码助理(PDA)、媒体播放器以及众多消费性电子设备中。
在过去，嵌入式应用通常使用专用的汇编语言代码。开发者必须撰写所有的硬件驱动程序以及接口。
自从Linux出现之后，以自由软件为主的核心与公用程序可被放进嵌入式设备有限的硬件资源中。典型的嵌入式Linux安装大概需要2百万字节(2M Byte)的系统存储器。
嵌入式Linux与其他嵌入式操作系统的比较如下：
  • 开放源代码
  • 所需容量小(最小的安装大约需要2MB)
  • 不需版权费用
  • 成熟与稳定(经历这些年的发展与使用)
  • 良好的支持

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...

Spoofing Cross-site request forgery Denial of service   Correct Insecure direct object references 2) Your application is created using a language that does not support a clear distinction between code and data. Which vulnerability is most likely to occur in your application? Injection   Correct Insecure direct object references Failure to restrict URL access Insufficient transport layer protection 3) Which of the following scenarios is most likely to cause an injection attack? Unvalidated input is embedded in an instruction stream.   Correct Unvalidated input can be distinguished from valid instructions. A Web application does not validate a client’s access to a resource. A Web action performs an operation on behalf of the user without checkin...
