If you are using a VPS or a dedicated server for your business site or a blog, then you have made a great choice in terms of privacy, power, performance and security. You can always enhance security of these servers by following some simple and practical tips for assured protection from hacking attempts that are growing in intensity as well as frequency.
Create complex passwords
Many individuals tend to follow a simplistic approach while coining username and passwords however, this can severely compromise security of a server by. Easy passwords can be guessed instantly by hackers who are already a step ahead in password guessing techniques. These cyber criminals have been using ultra-modern methods such as crypto-analysis tools
It pays to set an alpha-numeric password and change the same as often as you can. The right password can even be designed to include letters in upper and lower cases. Do not forget to store the password in a secured place or easy retrieval in case you forget password of your VPS or dedicated sever.
Use of a reliable Internet Service Provider
One must never try accessing the server from unprotected environments of public cafes or other places that offer free access to Wi-Fi enabled internet facilities. Generating a static IP through a reliable service provider and using it to block access points is a good practice in addition to firewall configuration.
There is a need to enhance security by frequent malware and virus scanning for arresting the potential assault by unsolicited programs. Moreover, you need to constantly monitor your server processes for messages and warnings. Failure to do so can be disastrous. A weekly error log checking must be scheduled to maintain sound performance of the server.
In short, one need not squander finances on premium security services for protecting VPS servers or dedicated servers. These simple and practical tips can enhance security quotient of your server if these are religiously followed.
Access protection- eliminate password use
Password usage is the universally accepted way to access server environment. However, thanks to unabated events of password hacks resulting into brute force attacks, it is not secure anymore.
The most obvious way for hackers to gain access to your server is through use of passwords. These have been set by users as root account passwords for their own use. This is not a secure way because guessing of passwords and usernames is the preferred modus operndi of attackers who try to shatter your server’s security through brute force attacks.
Prevention of automated brute force attacks can be achieved simply by changing SSH listen port from the default SSH Port 22 to a different port. If you follow this first step, then you will be preventing attackers that try to enter server environment by guessing passwords and user-names.
Then you need to make sure that you have generated an SSH key and allow users access the server by configuring it. This method reduces the probability of server being hacked for gaining an unauthorized entry by use of password.
Protection from brute force attacks can also be enabled by protecting vital points of server access. Alternative method of defending against such malafide attempts to log in into your VPS or dedicated server is by establishing a robust system for monitoring of frequent and unsuccessful login attempts.
This because modern hackers have means to leverage sophisticated computing systems that are designed to generate quick and multiple login attempts by guessing the passwords. The monitoring system is capable of simply blocking the IP address that is used by hackers to force entry into the system.
Reputed hosting service providers empower VPS and dedicated servers by including cPhulk for assured security against brute force attacks.
Security through SSL and TLS
Server administration should only be implemented by using interfaces that are secured by using Transport Level Security or TLS. This protocol is ideal for protecting communications between computers and servers through enhanced privacy. Any bit of data that is being exchanged between a VPS and a dedicated server hosting undergoes encryption. This simple protocol is extensively used for preventing hackers from accessing your server by stealing login information.
It is essential to adopt a dedicated SSL because even a self-signed SSL may not prove to be the most ideal way to secure your server. The dedicated SSL needs to be installed through VHM or SSH root.
Updating the software
There are some highly basic tips that could be overlooked even by expert web administrators. Software updates is one of the simplest and obvious ways to harden security of server. Performing routine updates is a mandatory exercise to keep your server in the nest pink of its health.
Obsolete software applications server as gateways to hackers who can easily break into your severs by exploring software entry points. Never make the mistake of declining an update because it can prove to be costly in the longer run.
