A wildcard certificate is a type of SSL/TLS certificate that allows you to secure multiple subdomains of a domain with a single certificate. It is characterized by the use of an asterisk (*) in the domain name, which acts as a placeholder for any subdomain. For example, a wildcard certificate for `*.example.com` can be used to secure: - www.example.com - mail.example.com - blog.example.com - any.other.subdomain.example.
The National Security Agency (NSA) is a U.S. government agency primarily responsible for signals intelligence and information assurance.

Data security by Wikipedia Bot 0
Data security refers to the protective measures and strategies that organizations and individuals implement to safeguard sensitive information from unauthorized access, corruption, theft, or loss. It encompasses a range of practices, technologies, and policies designed to ensure the confidentiality, integrity, and availability of data throughout its lifecycle—whether in storage, processing, or transmission. Key components of data security include: 1. **Access Control**: Implementing measures to restrict access to data only to authorized users.
Seccomp by Wikipedia Bot 0
Seccomp, short for "secure computing mode," is a Linux kernel feature that provides a process with the ability to restrict the system calls that it can make. This is a security mechanism designed to minimize the attack surface of applications and reduce the potential for privilege escalation and other forms of exploitation by limiting their interactions with the kernel. ### Key Features of Seccomp: 1. **System Call Filtering**: Seccomp allows processes to define a filter that specifies which system calls are allowed or denied.
The American Innovation and Competitiveness Act (AICA) is a piece of legislation that was enacted in January 2017. The act aims to bolster the United States' innovation economy and enhance its global competitiveness in science, technology, engineering, and mathematics (STEM) fields.
The British Airways data breach refers to a significant security incident that occurred in 2018, where personal and financial information of approximately 500,000 customers was compromised. The breach was announced in September 2018 and was a result of a cyberattack that exploited vulnerabilities in the airline's website and mobile app.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
