To help harden servers and networks, one important method is to disable unused services and ports. Servers often come with many services running by default, and not all of them are needed. Each open port or active service can be a way for attackers to get in. By turning off the ones you don’t use, you reduce the number of ways someone could attack your system.

Another helpful method is setting up strong password policies. This means requiring users to create passwords that are hard to guess, with a mix of letters, numbers, and symbols. Also, changing passwords regularly and not reusing old ones adds more protection. Weak or reused passwords are one of the most common ways hackers get access.

Some more ways to strengthen the security of servers and networks. When you combine these methods with other measures, like firewalls and regularly updating software, you can better protect against many cyber threats.
