Many arbitrageurs and owners of profitable utilities and applications choose to store data on rented servers, which is really convenient. However, this approach carries a significant drawback – vulnerability to attacks.
If the server is compromised, you may face the threat of losing access to all information, which negatively affects financial performance and reduces motivation.
That is why we have prepared a detailed guide that will help you protect your server from cyber attacks and avoid undesirable consequences.
Why protect your server
In most cases, hackers do not attack you specifically. Most often, their targets are team or product owners, or those who have become someone’s competitor. But regardless of what data is on the server and who owns it, it can still be subject to a hacking attempt.
The most likely scenario is an automated hacking with the help of specialized programs that look for security vulnerabilities.
Many arbitrageurs store passwords and access to tools, supplies, and offices on remote servers. If such a server is hacked, you risk losing control over your campaigns and supplies.
How to protect yourself from brute force
This type of attack is widespread, and its essence is to brute force a huge number of possible passwords.
However, there are methods that make the job of attackers much more difficult:
- Two-factor authentication (2FA) adds an additional layer of identity verification on every login attempt, making brute-force attacks virtually impossible;
- Fail2Ban – blocks the account on the server after several failed password attempts;
- Using SSH protocol distributes the attacker’s load by requiring not only the correct password, but also a specific IP address to log in.
It is important to note that even the longest password without these security features cannot completely prevent a brute-force attack.
How to protect yourself from DDoS attacks
A DDoS attack, also known as a denial-of-service attack, can paralyze almost any server. However, to prevent such a threat, it is enough to set up a barrier between the server and the network. CloudFlare and MediaGet are great solutions for this.
Tips for increasing the level of protection
Below are additional recommendations to help protect your servers from unauthorized intrusion:
- Limiting administrator rights – while root access provides great opportunities, it also poses a security risk. To perform tasks with elevated rights, use the /sudo command;
- Move to HTTPS – in 2024, it’s high time to ditch HTTP in favor of more secure protocols. If you’re still using HTTP, it’s time to switch to HTTPS;
- Savings when using SSH – if you are already using SSH, your data is automatically protected by encryption, which allows you to save money on switching to other protocols;
- Regular backups – create data backups every few days. This unshakable principle will allow you to restore important information in case of loss;
- Vulnerability testing – check your systems for weaknesses using various methods. This will help you identify and fix vulnerabilities before they are exploited by attackers.
- Investing in security – Ensuring reliable server protection is costly. For large teams, this is not likely to be a problem, as specialized software to protect against brute force attacks and DDoS can cost less than one employee’s salary. However, for safe growth and small projects, you should take care of your protection.
Conclusion
Regardless of the cost and level of server protection, none of them is 100% safe from hacking. However, basic security measures make the work of attackers much more difficult. Don’t ignore them so you don’t regret it later.
