Server Security
What is server security?
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.
To be most effective, security for servers should be arranged in layers. For maximum protection, you need to address potential issues in your network, the server’s operating system, and any applications or software hosted on your server.
Server security hardening
To ensure maximum protection of your server, you should complete the
process of server security hardening. In simple terms, that means
applying a combination of basic and advanced security measures to
address vulnerabilities in your server software and operating system to
boost overall server security.
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.
Common server security issues
Cybercriminals may be getting more sophisticated, but that doesn’t mean we should make it easy for them. Check the following list of common mistakes that cause server security issues and make sure that you and your employees are not making any of them:
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 Cybercriminals are constantly identifying and exploiting weaknesses in software, which means that running an outdated version significantly increases your risk of exposure.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.
