10 ways how server security services can protect your servers
Everyday, around 30,000 websites are getting hacked (source Sophos Lab). You wouldn’t want your business to be one among them. With new malware and threats emerging on a daily basis, one should always be on a constant alert.
By hiring an expert server security services, you can prevent a security attack before it strikes your servers. Bobcares helps server owners protect their servers from all sorts of exploits.
Our customers are able to focus on their core business without losing their peace of mind over server issues. Here, we’ll see the major security tasks we do, that help us provide a 360 degree comprehensive security to servers.
How we ensure 360 degree protection with our server security services
The main aim of a server security process is to secure your servers from all sorts of attacks and malware. This include 24/7 monitoring of vulnerable processes and attacks and periodic server audits to detect any breach.
1. Network security
Network is an easy entry point for attackers. The first thing we do is to secure the server network by blocking all unwanted ports from being accessed from external network.
We design network systems by segregating confidential data from the public network. By adjusting the network settings, we harden it against major attacks such as SYN flood, DDOS attack, etc.
We monitor the network traffic regularly and block attacking IPs and port scanning attempts. With the help of firewalls and other tools, we prevent direct access to back-end servers.
Other security tasks we perform include blocking spoofed and malformed connections, rate limiting ping packets, blocking blacklisted IPs, and so on, to avoid attacks.

2. In-depth server hardening
Here, we cover everything from user account protection to file system security. We secure user accounts with strong passwords that expire periodically and by enforcing secure user access policies.
By configuring SSL/TLS in all server services, we protect the user data and credentials being sniffed out by hackers. Using secure authentication systems like Kerberos is another way we foil sniffing attacks.
Other security tips include IP restriction for administrator access, using 2 factor authentication, locking account after multiple login failures and exercising other security practices.
The file system is further secured by controlling the access privilege of each user, restricting privilege execution of scripts and blocking malware execution in vulnerable directories such as /tmp.
System binaries are protected against unauthorized modifications that can lead to system infection. We also protect your operating system boot image against all malware infection.
3. Web server security
Web server is the most exposed service in any server. This makes it vulnerable to a wide range of attacks that can affect the web applications and related databases.
We configure Web Application Firewalls (WAFs) and malware scanners to block such attacks. All known attack patterns are blocked and signature databases are used to block all the common attacks.
With customized security rules such as mod-security, we restrict web operations to only the required ones. All processes and uploads are scanned in real-time to detect and block any malicious ones.
Securing the web server configuration is done to protect it, by preventing information disclosure, limiting privileges of web user, disabling obsolete and insecure modules, etc.
Limiting per-user resource allowance helps to prevent a single user abusing the whole web server. We also restrict user permissions to prevent one user from seeing another user’s data.
Deleting malicious files, enabling DDoS protection, enforcing SSL encryption for connections, using server hardening patches, etc. are some major activities we do to protect the web servers.
In addition, we monitor web traffic and log files for anomalies, keeping the software updated and with latest security patches. This helps us to prevent any malware from affecting these servers.
4. Database server hardening
Database forms a critical part of server as it stores many vital information. We tweak the database server to enable it to withstand information disclosure attacks.
Restricting user privileges, securely storing databases and backups, all these play a vital role in database server security. Enforcing strong passwords and restricting connections are other critical aspects.
DNS, SMTP, POP/IMAP, Remote Desktop, SSH, SSL, FTP, etc. are other critical services in the server which we secure as a part of our server security services.
