Without a reliable server, it’s impossible to effectively manage and launch your website or application.
A server is essentially a powerful machine that manages network-based access to data, software, resources, and services. Among the various server options, dedicated cloud servers stand out, particularly when discussing server security.
Dedicated cloud servers offer the exclusive use of server resources, ensuring optimal performance and security. Unlike shared hosting, where multiple users share the same server, a dedicated server provides a private environment, reducing the risk of unauthorized access.
When it comes to securing dedicated cloud servers, there are specific measures that can enhance protection against potential threats. In this blog, we’ll delve into the key security practices for dedicated cloud servers and explore the additional benefits that come with using a dedicated solution. Now let’s have a look at 7 Security Measures for Dedicated Cloud Server
What is a Dedicated Cloud Server
A dedicated cloud server is a type of cloud computing solution in which a single user or organization has exclusive access of an entire physical server. In contrast to conventional cloud services, which distribute resources among numerous users, a dedicated cloud server provides exclusive access to all hardware resources, such as memory, storage, bandwidth, and computing power. With this configuration, users can completely tailor the server environment to their unique requirements, including the operating system, installed apps, and security settings.
These servers combine the flexibility and scalability of cloud computing with the high performance, control, and security of dedicated physical servers, all managed and hosted by a third-party cloud provider. In addition, the provider handles the administration of the hardware, network, and infrastructure and frequently provides extra services like technical support, backup, and disaster recovery. Dedicated cloud servers enable for resource optimization and cost-effectiveness while guaranteeing improved speed, stability, and data protection. They are perfect for companies with sensitive data, resource-intensive applications, or websites with heavy traffic.
Security Measures for Dedicated Cloud Server
When managing a dedicated cloud server, security should be a top priority. The following security measures are essential to ensure your server is protected from potential threats:
1. DDOS Protection
Preventing Distributed Denial-of-Service (DDoS) assaults on your dedicated server is essential to keeping your online services up and running smoothly. A denial-of-service (DDoS) attack attempts to overload your server with traffic, causing problems and blocking genuine users from accessing your website or applications. It is imperative that you select a dedicated hosting package with integrated DDoS protection if you want to protect your server. To guarantee that your users have continuous access, this protection keeps an eye on incoming traffic, filters out harmful requests, and permits legal traffic to flow through.
Comprehensive defense requires the implementation of additional security measures in addition to built-in DDoS protection. By providing an extra buffer against erratic traffic spikes, overprovisioning bandwidth can keep your server from becoming overloaded. Additional security layers can be provided by third-party DDoS protection services, which identify and stop attacks before they even reach your server. One way to limit the amount of traffic a single user can transmit and lessen the chance of getting inundated by a single source is to configure rate limiting on your server. In severe situations, hostile traffic can be redirected and analyzed using methods like sinkhole and blackhole routing.
Having an emergency response plan in place is also essential to ensure prompt action in the event of an attack. With your hosting provider, go over your security options. Then, choose the most dependable options—including DDoS protection—from the list. Combining these techniques will help you defend your dedicated server from DDoS attacks and guarantee the ongoing availability of your online services.
2. Backup
A comprehensive backup strategy is an essential security measure for dedicated cloud servers, acting as a critical safety net against data loss or corruption. Regular backups are indispensable, ensuring that in the event of data loss, whether due to hardware malfunctions, cyberattacks, or natural disasters, your data can be swiftly recovered. To safeguard your data effectively, it’s crucial to schedule backups at appropriate intervals—daily, weekly, or monthly—based on how frequently your data changes.
Storing backups offsite is another key strategy. Whether you choose cloud storage or a different physical location, keeping your backups separate from your server helps protect them from physical disasters, such as fires or floods, that could affect your primary data center. Moreover, regularly testing your backups is vital to ensure that they can be restored successfully. This practice not only verifies the integrity of your backups but also confirms that the restoration process will work when needed.
Automation can simplify the backup process, with various tools and services available to handle everything from creating backups to encrypting and transferring them to secure offsite locations. It’s also important to remember to back up server configuration files. Having these original configurations handy can make the restoration process much more straightforward in the event of a server failure.
Even with all these measures in place, the unpredictable nature of disasters or cyberattacks means that no system is entirely foolproof. Therefore, maintaining regular data backups is a crucial fallback option, ensuring that your information remains secure even in the worst-case scenario. Implementing a 3-2-1 backup strategy—creating at least three copies of your data, stored on two different mediums, with one copy stored offsite—provides an additional layer of security. Ultimately, while protecting your dedicated cloud server from malicious attacks is vital, preparing for the worst by maintaining robust backups will enable you to quickly retrieve your data and minimize downtime, preserving your business’s reputation and continuity.
3. SSH Port
Having secure SSH access to your cloud server is essential for thwarting potential assaults and unauthorized access. Changing the default SSH port, which is typically set to port 22, is one of the greatest ideas. You can lessen the chance that the scanning technique will target your server by changing the SSH port to a non-standard port, particularly one greater than 1024. This modification has the same unfavorable effects as relocating the login to a less noticeable location.
For the changes to take effect, use the new port and restart the SSH service. Care should be used while choosing a new port, though; ports greater than 1024 are advised as they are less likely to be connected to well-known services. and are typically outside of the range that hackers look for.
It has a port switcher function. Since it stops hackers from attempting to brute force the root account, disabling direct login is crucial. It is safer to log in as a limited user with specific permissions instead. Because SSH key-based authentication requires a private key in addition to a password, it improves security and offers robust defense against attacks. To enhance security, think about using two-factor authentication (2FA), which demands users to submit both something they possess (like a mobile phone or token) and something they know (like a password).
Generally speaking, employing SSH keys, modifying the port, preventing root access, and preventing SSH access to your cloud server, and turning on 2FA are crucial actions to strengthen the security of your server overall and prevent unwanted access.
4. Strong Password Policy
When it comes to protecting a dedicated cloud server from unwanted access, a robust password policy is your first line of protection. Initially, avoid using default passwords as they are frequently weak and simple to guess. Instead, make passwords that are at least eight characters long by combining capital and lowercase letters, numbers, and special symbols. Their complexity makes them hard to find or understand.
To further enhance security, make sure your passwords don’t contain any information, characters, or numbers connected to your identity. These kinds of details are simple for attackers to interpret. To prevent possible security breaches, you must update or reset your password at least once every two to three months.
Consider combining safe passwords with two-factor authentication (2FA) for an additional degree of protection. It works as a second layer of protection that makes it much harder for unwanted users to get access by demanding secondary authentication in addition to a password.
You may significantly lower the risk of internet attacks, safeguard your data, and keep up your good reputation as a business owner by heeding this advice.
5. Removing unused Software
Eliminating unnecessary applications and services is a crucial step in keeping a dedicated cloud server secure. Unused software is very vulnerable because, once you stop using it, it’s simple to forget about it and, as a result, it frequently doesn’t receive important security updates. These out-of-date and neglected apps can be used as entry points by hackers to access your server without authorization and possibly compromise sensitive data. Consequently, keeping an eye out for and eliminating superfluous services on a regular basis is crucial to protecting your server.
You can examine the services that are operating on your server and determine which ones are not necessary for it to function by using tools such as netstat. Once these pointless services have been located, it’s best to disable them or, if that’s not possible, uninstall them completely if they won’t be needed in the future. By taking a proactive approach, you may lower the amount of potential vulnerabilities and maintain the security of your server environment.
Furthermore, since software updates frequently contain essential security patches, it’s crucial to maintain all active software up to date. These updates are similar to mending faulty locks on the security of your server. It is imperative to stay up to speed with updates because failing to install these fixes can result in security breaches.
Make frequent inspections for unused software and services in order to guarantee continued security. This procedure will support the upkeep of a hygienic and safe server environment.
Additionally, you should always delete any software or services you test but ultimately decide not to use because these can be easily forgotten and eventually turn into vulnerabilities. By regularly getting rid of unnecessary software and making sure everything is current, the likelihood of security breaches on your dedicated cloud server can be greatly decreased.
6. Securing Database
Securing your database on a dedicated cloud server is critical, as it holds sensitive information that is a prime target for cybercriminals. One of the most common and dangerous methods attackers use is SQL injection, which allows them to insert malicious SQL queries into your database, leading to data manipulation or theft. To protect your dedicated server from such threats, it’s essential to implement robust security measures.
First, you should limit user privileges to the bare minimum. Only those who absolutely need access should have it, and their permissions should be restricted to the lowest level necessary for their role. This reduces the potential damage if an account is compromised. Additionally, it’s crucial to eliminate any unnecessary data, services, and files from your server. Unused elements can be exploited by skilled hackers, providing them with entry points into your system.
Another key strategy is ensuring your database is resistant to SQL injection attacks. This involves implementing best practices like input validation and using prepared statements, which prevent attackers from executing unauthorized queries. Furthermore, it’s important to minimize the areas of interaction between customers and your database. By limiting direct access, you reduce the likelihood of a successful attack.
In summary, securing your database on a dedicated cloud server requires a multi-faceted approach: restrict user privileges, remove unnecessary data and services, and make your database resilient against SQL injections. These steps significantly reduce the risk of server compromise and protect your sensitive data from being exploited by cybercriminals.
