memcache

Memcache itself does not have a permission control module, so the memcache service open to the external network is easily scanned and discovered by attackers. Sensitive information in memcache can be directly read through command interaction.

To solve this problem, you can follow the following solutions:

1. Memcache is not provided for external network access

memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211 -c 1024 -P /tmp/memcached.pid

2. Memcache needs to be provided for external network access Open the firewall for network access

iptables -A INPUT -p tcp -s 192.168.0.2 --dport 11211 -j ACCEPT

The above rules mean that only the ip 192.168.0.2 is allowed to access port 11211.

The above is the detailed content of memcache security related. For more information, please follow other related articles on the PHP Chinese website!

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
