A recent report shared by Accenture revealed that a cyberattack, which is in the form of malware, might cost around 2.6 million dollars to businesses. Another study revealed that incidents related to data breaches cost around 8.64 million dollars in the United States. The increasing number of cyberattacks has got several businesses worried.
Due to this, both small and large-scale businesses have been looking for a way to ensure the server’s security, which is hosting the data of their business. If you want to have a secure server at your business, you will need to follow some essential security measures.
Prevalent Security Risks In 2020
Several cybersecurity experts firmly believe that cross-site scripting, code injection, and DoS attacks are the most prevalent security risks businesses face in 2021. During a DDOS or DoS attack, attackers will try to overflow your business server with falsified requests or junk data.
Code injection is a type of cyberattack where a hacker exploits a vulnerability in the security systems. As a result, your app or website will be changed by hackers for their uses.
XSS or cross-site scripting can be defined as a web app vulnerability, enabling cyberattackers to send malicious or misleading requests to your web browser. However, do not worry because here are a few tips that will help you to secure your server from cyberattackers.
Establish A Secure Connection
Businesses need to establish a safe and secure channel to communicate when connecting to a remote server. It is best to use the Secure Shell Protocol (SSH) when you are establishing a connection. SSH access will encrypt all data, which is transmitted during the exchange.
You can also use other security protocols like HTTPS, FTPs, and sFTP instead of plain FTP, telnet, and other insecure communication protocols. If you are using SSH, it is best to change the SSH port from the default. This will give you protection against attackers who are looking for vulnerable servers.
Secure File Transfer Protocol
Several businesses make use of FTPS or File Transfer Protocol Secure these days. FTPS does an excellent job of preventing hackers from stealing or compromising data. As a result, businesses can easily transfer files to and from their business servers without any worries.
FTPS makes use of a data channel and command channel, which means that the user will be able to encrypt both. However, it is important to note that FTPS will protect files only during the transfer process. The data will not be encrypted when they reach your business server.
Businesses, irrespective of their sizes, should consider investing in SSL certificates. If you purchase SSL certificates for your business, you will secure web administration forms and different pages of a website like admin login page, etc.; SSL can be used both for server-server and server-client communications.
Most internet users will be able to easily understand websites that have installed SSL certificates. This is because such websites will contain HTTPS at the beginning of their URL. The HTTPS in the URL indicates that the website is safe and secure.
Monitor Login Attempts
Businesses who want to ensure that their server is secure should also consider using an intrusion prevention software system. An intrusion prevention software will enable businesses to easily monitor login attempts.
Automated attacks often use trial and error methods by attempting every possible number and letter combination to gain access to business systems.
Intrusion prevention software helps businesses by overseeing all log files and by checking for suspicious login attempts. If the number of login attempts exceeds, the software will block the IP address indefinitely or for some time.
It is crucial to remember that every server will have a root user who will execute all commands. The root can be an issue for some businesses, especially if it ends up in the wrong hands. This is why most businesses prefer to disable the root login.
The root user will be the one with more power in your enterprise. So, most hackers will try to crack the password of the root user. In simple words, disabling the root login will help you to prevent your business server from potential cybersecurity threats.
If you want to ensure that any outsider does not misuse the root privileges, you should consider creating a limited user account. Such an account will not have the same authority as a root account, but the user can use audio commands for performing administrative processes.
The first and most important thing businesses should do to ensure the safety of their server is to set password rules and requirements that should be strictly followed by everyone who is using the server. The first and most important thing businesses should do to ensure the safety of their server is to set password rules and requirements that should be strictly followed by everyone who is using the server. For example, it would be best if you never allowed employees to set default or empty passwords.
Instead, businesses should ensure that all employees are using strong passwords that are hard to crack. It is also not a good idea to store passwords by using reversible encryption. Enabling two-factor authority and forcing session timeout for inactivity will ensure greater protection.
Regularly Upgrade And Update Software
Updating the software on your business server is another effective security measure that will help you avoid cyber attacks. Hackers and cyber attackers may explore an outdated software system for vulnerabilities. You will be able to avoid such issues by regularly updating the software.
Automatic updates are undoubtedly an excellent choice because no updates will be forgotten. However, the issue with automatic updates is that allowing systems to make changes independently is quite risky. If you are using content management systems, then you will need to regularly update them too.
Some of the security measures listed above must be done when the server is initially installed, while some measures are part of periodic or continuous maintenance. If you follow these suggestions on securing a server, you will surely feel confident knowing that your business server is secure and safe.
