Despite the fact that virtual private servers (VPS) have been around since the early 2000s, many users still don’t understand how important it is to use this service properly and in a secure manner. This article is designed to help South Korea VPS users understand the common mistakes made with their server usage, along with providing solutions on how to avoid these pitfalls altogether. Keep reading to learn about 10 ways to keep your South Korea VPS safe and secure!
Turn on 2FA
When it comes to securing your South Korea VPS, you have a lot of different options. One of these is two-factor authentication (2FA), which can be done via SMS, a physical USB token, or an app on your phone. 2FA makes it much harder for hackers to get into your server by requiring a second form of verification before they can log in successfully. Even if someone steals your password, they’ll need access to your cellphone or other secondary devices in order to gain entry; we recommend using either Google Authenticator or Authy for South Korea VPN providers. Turn them on!
Change Your Default Password
Just changing your password from its default is a great first step. And don’t be tempted to use something simple like admin or your own name—choose something that’s hard for hackers to guess but easy for you to remember. You might also consider using two-factor authentication, which requires users not only to enter their password but enter a unique code that’s sent as a text message before they can log in. This makes it much harder for hackers, who won’t have access to both your password and your phone number, while still allowing you unlimited login attempts if you forget your password!
Use a VPN
Virtual private networks, or VPNs, are among the best security practices for keeping your South Korea VPS safe. A VPN lets you create a secure connection to a server, which can help protect you from outside threats (it’s like having an in-house firewall). To use a VPN on your South Korea VPS: 1) Pick a trustworthy provider; 2) Get it installed; 3) Configure it. If you’re going to invest in a South Korea Virtual Private Server, treat your data like gold—because that’s what it is. You should approach keeping your data secure with just as much thoughtfulness as finding your data center in South Korea.
Check Billing Details Regularly
Most providers will bill you based on your actual server usage, meaning that overages could be expensive. Stay informed about your server’s charges by reviewing them regularly (most providers offer online billing tools that send you an email notification when it’s time for payment). You should also make sure you’re aware of any limitations on bandwidth or other resources. For example, some servers are limited to one IP address. That means if you have multiple sites hosted on your server, they’ll all share one address—which can cause technical problems down the road. That’s why it’s important to know exactly what kind of setup your provider offers before signing up for a South Korea Windows VPS Hosting account.
Set Up Web Application Firewall (WAF)
A Web Application Firewall (WAF) is an additional layer of security on your site that monitors traffic in real-time. They generally consist of a set of rules programmed into a server-side application that monitors incoming traffic against preset rules. If one or more conditions are matched, the WAF responds by either rejecting the connection or taking some other action. Some WAFs have access control mechanisms that limit actions such as modifying data. Firewalls can protect against common hacking attempts such as SQL injection attacks, buffer overflows, and cross-site scripting (XSS). By preventing unauthorized external entities from accessing a website’s back end or hosted content management system through these methods, they prevent web application exploitation.
Lock Down SSH Access
While a lot of good can come from using SSH, it’s also a major security risk. To keep your server secure, only allow SSH connections from your specific IP address or network. This will ensure that no one can gain access without being able to log in through you first. Another best practice is to choose unique, non-obvious user names and passwords for each account on your system. If you have multiple users with access, they should all be given unique accounts as well; standardizing them makes it easy for someone else to guess usernames or passwords later on. To go above and beyond with security, consider using PAM (pluggable authentication modules) or an alternative authentication method like multi-factor authentication via One-Time Passwords or hardware tokens.
Protect Yourself Against DDoS Attacks
The primary function of a DDoS attack is to overwhelm your server’s bandwidth. This results in two problems: first, your users will have a harder time accessing data because of unusually high traffic on your server; second, they’ll be frustrated by long load times when trying to access something as simple as an email account. To help mitigate these attacks, consider purchasing some basic DDoS protection or web application firewall (WAF) services for your server. It won’t protect you completely, but it will keep you safe in almost all cases (and if it doesn’t stop every single attack from being successful, it can at least slow them down). Basic solutions typically involve subscribing to a third-party service that provides protection against DDoS attacks for around $2-$5 per month per server.
Install Latest Software Versions on Machines
Keeping your server software up-to-date not only patches your system against security holes, but also ensures that you have access to any recent bug fixes or feature improvements. To do so on Debian-based Linux distributions such as Ubuntu or Mint, execute sudo apt-get update && sudo apt-get upgrade -y The first command downloads all new packages, while the second one installs them. Be sure to reboot your machine once completed!
Update Apps Regularly
With dozens of applications running on your server, it’s important to know what they do. Some might be doing work in the background that you’re not aware of or generating server errors. To make sure things are running smoothly, regularly update your apps as well as your operating system. Things like Apache, MySQL, PHP, and OpenSSH should always be updated when new versions are released. Always make sure you use password protection, 2-factor authentication (when available), and a VPN with any service you use; even if you don’t share sensitive information via email, these three things will help keep others from hacking into your account while using public wifi.
Use a Dedicated IP Address
A dedicated IP address is a permanent Internet Protocol (IP) address that is assigned by your hosting provider to a single website. In order for multiple servers on a shared server to have different IP addresses, you’ll need to purchase a proxy service from your hosting provider. It may seem like an extra expense at first, but dedicated IP addresses can help prevent malicious hackers from scanning your site for security holes. Dedicated IP addresses also allow you more control over who has access to certain administrative functions of your site because no one else will be using that particular IP address except for you and anyone you authorize.
