Analysis of Common PHP vulnerability attacks and php vulnerability attacks
Summary: PHP programs are not solid. With the widespread use of PHP, some hackers do not want to bother with PHP, and attacks by using PHP program vulnerabilities are one of them. In this section, we will analyze the security of PHP in terms of global variables, remote files, file uploads, library files, Session files, data types, an

Share ssh usage records in Ubuntu and ssh in ubuntuThis article is based on Ubuntu 16.04. 1. Install
Sudo apt-get install openssh-server2. Configuration
The configuration file is located in/etc/ssh/sshd_config.
The default port is 22, which can be modified in the configuration file or added to allow ssh to listen to
The default SSH port is 22. It is strongly recommended to change to more than 10000. So the probability of others scanning to the port is also greatly reduced. How to modify: # Edit/etc/ssh/ssh_configVim/etc/ssh/ssh_config
# under Host *, add a new Port value. Take 18439 as an example:
Port 22

A typical node application may have hundreds of or even thousands of packages dependent (most of the dependencies are indirect, that is, to download a package that relies on a lot of other packages), so the end result is that the application will look like this: The amount of code you write is less pathetic than the package you depend on. The introduction of a large number of packages into the code of the application, but also introduced some unpredictable pitfalls, such as whether we know if th
Gravitational teleport is an advanced SSH server that can access Linux servers remotely via SSH or HTTPS. Its purpose is to replace sshd. Teleport can make it easy for teams to use SSH with best practices, such as:
No need to distribute keys, teleport use certificate-based access and implement automatic expiration
