What is Server Security?

Server security refers to the procedures and equipment used to safeguard the important information and assets stored on a company’s servers, as well as the resources of the server itself. Cybercriminals often target servers because of the sensitive data they store and try to take advantage of security flaws in order to profit financially.

Now more than ever, keeping your server secure is simple.Large numbers of people can access the same data or functionality, frequently remotely, thanks to servers, which are at the core of an organization’s IT infrastructure. They are typically utilized to host files, power the internet, and operate email services. The issue is that a user error, a weak password, or a lack of antivirus software could all result in significant losses for the company.

Layered security is the optimal configuration for servers. You must take care of any possible problems with your network, the operating system of the server, and any programs or software hosted on the server if you want the highest level of safety.An illustration of how server security is the focal point of IT infrastructure security, encompassing files, email systems, and the internet.

Should I be concerned?

Cybercriminals pose a serious threat to organizations, and the stakes are quite high. According to Juniper Research, the moderate cost of a data breach would rise to $150 million by 2020. In addition to the immediate financial loss, a security breach may give rise to bad press that harms a company’s reputation and brand. Small firms are not immune to the controversies surrounding massive data breaches, despite the fact that Yahoo and Marriott International are just two of the well-known names involved. Small firms are the mark of 43% of cyberattacks, according to an Accenture survey.

Even while cybercriminals may be becoming more skilled, we shouldn’t give them an easier time. Make sure none of the following mistakes—which are frequently made and lead to server security issues—are being made by you or your staff.Icon_01Passwords.

Server security hardening

Your server should be fully protected if you have finished the server security hardening process. To improve overall server security, that essentially involves addressing weaknesses in your operating system and server software by combining basic and advanced security measures.

Common techniques for hardening servers include:

  • Making secure passwords confirming that data is encrypted during communications
  • completing routine backups of the system Update
  • operating systems and install security updates as soon as they are made available.
  • Eliminating superfluous third-party applications installing antivirus and firewall programs.
  • Bringing out penetration tests on a regular basis.

How to secure your server

Seeking advice on server security can yield an overwhelming amount of technical data. We’ve simplified things in this section by dissecting the primary web-server security best practices that you ought to adhere to for efficient security.

Use a secure connection

Brute-force attacks, in which hackers test a huge array of letter and number combinations using sophisticated algorithms, are a potential threat to password security. Using Secure Shell (SSH) to create a secure connection with your server is a more secure option for authentication than using a password. A pair of cryptographically secure keys, a public key and a private key, make up SSH keys. While the private key must be kept absolutely confidential by the user, the public key may be shared without restriction. All data transferred over SSH is encrypted.An additional coating of protection can be provided by using a proxy server. Proxy servers make it more difficult for pirates to target certain devices and grant access by hiding all users on your network behind the proxy’s IP address.

Connect via a private network or VPN

Using a private network or virtual private network (VPN) to guarantee secure data communications is another advised security technique. By using a private IP address, access to a private network is limited to specific users or servers. When contacting distant servers over a VPN, the same setting can be attained. This provides users with the same capabilities as if they were connected to a local private network while encrypting data to and from the server. Make use of SSL/TLS

What the experts say

Maintaining patch-adequate infrastructure is the most basic security countermeasure that defenders may take. Particularly for the infrastructure that faces the Internet. For infrastructure that is exposed to the Internet and is both internal and external, prevention should come first. Threat hunting specialist David Álvarez Pérez and Linux malware reverse engineer Jan NeduchalThreat Avast Labs Another strong defense is server security certificates. Cryptographic technologies used for encryption and authentication include TLS (Transport Layer Security) and SSL (Secure Sockets Layer). Server security certificates are a part of these protocols. To put it simply, they secure network connections by encrypting private information sent over the internet, including usernames, passwords, and payment card numbers, so that servers can verify the legitimacy of the entities.

Regularly update your operating system

Making sure you are constantly running the most recent operating system version is a crucial step in protecting your server. Hackers frequently find flaws in software, which engineers subsequently try to fix. Updates should be deployed right away, ideally automatically, and are published as security patches. Your operating system and any other software that runs on your server become vulnerable to known flaws if you don’t keep them updated. Also check How To Fix DNS Server Unavailable

Configure the OS based on best practice guidelines

Make sure your operating system is set up in accordance with server security best practices for the best protection. These consist of, but are not restricted to:

  • Changing any installed third-party software’s default passwords
  • limiting user privileges to the absolute minimum required for the person to perform their duties
  • Disabling or deleting any unused accounts
  • Setting strict password regulations and making sure all system passwords adhere to them
  • Turning off any programs or services that are not needed.

Server security checklist

Now that you are aware of what constitutes good security, make sure you have everything covered by going through our helpful server security checklist. Everything you need to do, from initial setup to ongoing maintenance, will be guided by us.

  1. Note the server’s information. First things first, find and write down every crucial piece of information about your server, including the MAC address and server identification number.
  2. Think about taking physical precautions. Even though there is a virtual threat of attackers accessing the server, you should think about implementing physical protections to prevent unwanted access. As few persons as possible should be able to enter the server room, and keys should be kept safe.
  3. Configure the logging on the server. Keep an eye on things and set up event records to facilitate traceability. In addition to tracking account logins, authorization modifications, and system configuration changes, keep an eye on the remote access logs and investigate any questionable activities. Think about storing log backups on a different log server.
  4. Don’t try to fix flaws. Verify that the most recent versions of the operating system, any additional software, and any apps are installed.
  5. Limit software. Eliminate any operating system or software that is not in use or is not required. In a similar vein, all unused services ought to be turned off.
  6. Observe the hardware. Perform normal hardware maintenance and periodically check your server for any worn-out or broken parts that might require replacement.
  7. Maintain the integrity of the system. Use strong authentication techniques for all system administrators, such as two-factor authentication. Eliminate any accounts that are not required any more.
  8. Put backup plans into action. Make an effort to automate routine server backups and make sure everything is working as it should. You should periodically test recovery pictures.
