Malware attacks are now a regular affair that businesses and individuals are facing time and again. Recently, we have noticed a rampant increase in malware attacks and hacking attempts. These attacks have caused major damage to businesses and users alike in the form of revenue loss and sensitive data being compromised.
Irrespective of the web server software or operating systems (Microsoft Windows, Linux) you use, you need to put in place certain stringent security measures to protect your servers from unfortunate attacks. It's therefore very important to monitor your server configuration against any possible security breach.
7 Server Security Measures To Keep Your Server Hack Proof
Being leaders in web hosting, we always recommend clients to adopt multi-faceted security measures. Needn't to mention that multiple security measures adds an additional layer of defense against attacks.
We are listing here some very crucial server security hacks that collectively will help you strengthen your web server security and prevent cyber attacks.
1. Automate Security Upgrades :
Version upgrades and patch updates help you prevent possible cyber threats and malware attacks. An obsolete or outdated product version prone to vulnerabilities and malicious automated exploits. Product manufactures tend to release patch updates and security upgrades very frequently. You may switch to automatic updates, to update your software, add-ons and plugins as soon a new version is available.
Brainpulse offers dedicated servers for entrepreneurs and small businesses with flexibility to configure their own server by choosing a range of customization options.
2. Monitor Server Status and Server Security:
You should be vigilant enough to quickly review the running status of servers and spot threats if any. Check for any potential problems with CPU, RAM, disk usage, running processes and other metrics. It will help you detect vulnerabilities and server security issues relatively faster. All kind of server logs including network services logs, site access logs, database logs (Microsoft SQL Server, My SQL, Oracle) should be stored in segregated areas and must be monitored frequently.
3. Implement Perimeter Security With Firewalls:
A server can only be secured if its security applications as well have great security measures in place. Means server's border routers and firewalls set up should be designed to locate and neutralize threats, automated attacks, malicious traffic, DDoS filters, bogon IPs, and untrusted networks. Go with local firewalls to actively monitor and detect attacks. Moreover, a web will firewall will be helpful in filtering those malicious web page requests that are deliberately made to break or compromise a website.
4. Use Advanced Security Tools:
You may have access to a number of advanced server security tools to protect your web server installations. Despite the fact that configuring these tools are tedious and takes time, they help you add an extra layer of security and give you peace of mind.
Take the example of Scanners- They help administrators automate the process of running advanced security checks against the open ports. This is useful as it ensures complete security of servers and web applications. They can automatically audit shopping carts, forms, dynamic web content and other web applications and provide detailed reports on vulnerabilities.
5. Remove Unnecessary Services:
Default server and operating system configurations are prone to malware attacks and threats. If you allow multiple unnecessary services to run on the default operating system, resources might be compromised. This is why we recommend you to either remove or switch off all unnecessary services and disable them. Doing this will help you protect your server and by freeing hardware resources you can improve your server performance.
6. Keep Eye on Web Application Content:
It's advised to keep web application or website files and related scripts at different places. They shouldn't be mixed with operating system files, folders and logs. This helps you protect web servers from hackers even if they manage to gain access to the web root directory. Since, files and folders are stored at different locations, hackers can't use any operating system command to take control of the web server.

7. Strict Access Permissions:
If there are multiple users using the applications and resources, strict user roles using file and network services permissions. Such permissions are effective in combating attacks and preventing potential damage from a compromised account. Hackers use the accounts to manage access to execute specific files.
Be frequent with file system permission review to prevent users from executing a service he is not authorized to carry out. You may also want to restrict powers what each user or service can do.
