Every year, there are an increasing number of cyberattacks. According to TechTarget, Skybox Security reported an increase of 25% in new vulnerabilities in 2022 compared to 2021. Moreover, the World Economic Forum's Global Risks Report 2023 predicts that the concerns around cybersecurity will persist in 2024, too.

In this era of digital threats looming large, virtual private servers (VPS) offer a beacon of hope. With a VPS server, you have a powerful tool in the fight against cybercrime by offering a secure and flexible alternative to traditional hosting solutions.

This article will explore how a virtual private server enhances cybersecurity and the best practices for keeping it secure.

Understanding Virtual Private Servers (VPS)

According to OVHcloud, a virtual private server hosts websites and software. However, unlike traditional hosting, it is isolated from other users while operating in a larger shared server. This isolation provides dedicated resources and greater control over the server environment.

It ensures that the actions of other users on the server do not affect the performance or security of your VPS. Due to these benefits, the market is estimated to grow exponentially at a CAGR of 14.53% until 2030. As stated in a Global Newswire report, it is predicted to reach $7.8 billion by then.

How Virtual Private Servers Play Their Part in Cybersecurity

VPS plays a crucial role in cybersecurity by providing a secure and isolated environment for hosting websites, applications, and other online services. Here's how it contributes to cybersecurity:

Enhanced Control and Customization

Enhanced control and customization of a VPS are pivotal in improving cybersecurity measures. By giving users greater control over their server environment, VPS enables them to implement tailored security configurations to meet specific needs. This level of control allows users to install and configure security software, apply patches promptly, and enforce stringent access controls.

Users with customization options are able to apply multi-layered security measures that are specific to their needs. They can deploy firewalls, intrusion detection and prevention systems, antivirus software, etc., to fortify their VPS against cyber threats. This flexibility enables users to adapt their security posture to evolving cyber threats and vulnerabilities.

Enhanced control over system resources allows users to closely monitor and manage their VPS server environment, enhancing security. Through monitoring resource usage patterns, users can identify unusual activities that may indicate a security breach and promptly take corrective action.

Moreover, granular control over system resources enables users to allocate computing resources judiciously. This helps prevent resource exhaustion attacks such as Distributed Denial of Service (DDoS).

Isolated Environment

The isolation creates a distinct boundary between the VPS and other hosting accounts or servers on the same physical machine. Each VPS runs independently, with its own set of dedicated resources, such as CPU, memory, storage, and network bandwidth.

This isolation prevents the "noisy neighbor" effect, where activities or security vulnerabilities in one server impact those sharing the hardware. By segregating resources, a VPS minimizes the risk of unauthorized access or data breaches stemming from vulnerabilities in other accounts.

Moreover, the isolation provided by a VPS limits the potential attack surface. With its dedicated operating system and software stack, a VPS reduces the likelihood of security vulnerabilities arising from interactions with other software. This isolation also makes implementing security measures tailored to the VPS's specific needs easier without being affected by configurations in other environments.

Dedicated Resources

When users have dedicated resources, they have more control over their server environment. They are not impacted by other users' configurations or vulnerabilities, allowing them to adopt more stringent security measures customized to meet their unique requirements. This includes encryption protocols, firewalls, and access controls to protect sensitive data and stop illegal access.

Moreover, the availability and integrity of security measures depend on consistent performance, which is guaranteed by dedicated resources. By avoiding resource contention with other users, VPS users can better manage their server's workload and allocate resources efficiently to security-related tasks.

The dedicated resources also help improve performance, especially of modern-day technologies. For instance, a HackerNoon article states that VPS can help advance the performance of augmented reality (AR) for smartphones. It can help identify position and orientation with 0.5-meter accuracy.

This increased performance also resonates with quick threat response. Additionally, optimized applications have fewer vulnerabilities and a reduced attack surface, which makes them less susceptible to exploitation by attackers. More performance and specialized resources allow for the use of more robust encryption algorithms. It helps improve the efficiency of authentication mechanisms without sacrificing speed.

Best Practices for Securing a Virtual Private Server

Despite the built-in security benefits of a VPS, best practices must be followed to optimize defense against online threats. The following are some essential methods for protecting your virtual private server:

Regular Software Updates

Updating your server's software and operating system is crucial for patching security flaws and defending against known exploits. To ensure your server is running the most recent security patches, set up automatic updates wherever feasible and regularly check for updates manually.

Strong Authentication Mechanisms

Implement robust authentication mechanisms, such as SSH keys, multi-factor authentication (MFA), and strong passwords, to prevent unauthorized access to your VPS. Disable password-based authentication for SSH and switch to key-based authentication to bolster security even further.

According to a Zippia article, 99.9% of all modern-day vulnerabilities can be blocked using MFA. Sadly, only 13% of small-medium business employees are asked to use MFA. On the other hand, 87% of employees at large organizations are required to use MFA for security.

Firewall Configuration

Set up a firewall on your VPS to manage incoming and outgoing traffic and prevent unauthorized users from accessing critical services. Use firewall rules to whitelist trusted IP addresses, restrict access to specific ports, and filter incoming traffic based on predefined criteria. This minimizes the risk of unauthorized access and mitigates DDoS attacks.

Monitoring and Intrusion Detection

Set up monitoring tools and intrusion detection systems (IDS) to monitor server activity, detect suspicious behavior, and alert you to potential threats. Monitor system logs, network traffic, and server performance metrics to identify anomalous activity and take timely action to mitigate security risks.
