Server security covers the processes and tools used to protect the valuable data and assets held on an organization’s servers, as well as to protect the server’s resources. Due to the sensitive information they hold, servers are frequently targeted by cybercriminals looking to exploit weaknesses in server security for financial gain.
Servers sit at the heart of an organization’s IT infrastructure and allow large numbers of users to access the same information or functionality, often remotely. Generally, they are used to run email systems, power the internet, and host files. The problem, though, is that something as simple as a weak password, missing antivirus software, or user error could expose the business to substantial loss.
Common server security issues:
Passwords. Weak passwords can be easily hacked, and poor security controls can lead to passwords being stolen and sold on the dark web. Consider using a password manager if you’re concerned about the integrity of your passwords.
Old software/operating systems. Cybercriminals are constantly identifying and exploiting weaknesses in software, which means that running an outdated version significantly increases your risk of exposure.
Patch management. By using a patch management service, you can ensure any changes in code are acquired, tested, and installed.
Open network ports. Misconfigured servers can be easily exploited.
Old and unnecessary accounts. Unused accounts offer hackers an additional way in.
Poor physical security. Not all threats are virtual. Poorly secured keys can be just as dangerous.
Common ways to achieve server hardening include:
- Using strong passwords
- Ensuring that communications are data encrypted.
- Completing regular system backups
- Keeping operating systems up to date and applying security patches as they are released.
- Removing unnecessary third-party software
- Installing firewalls and antivirus software.
- Conducting regular penetration tests.
Conclusion: Strong server security is essential for securing your company since attackers are coming up with more complex ways to attack. Thankfully, it doesn’t have to be difficult. We will define server security in this post and demonstrate how to set up a fully secured server.
