Sharing files is common for small businesses and enterprises alike, but it’s important to do so securely to protect sensitive data. For most companies, cloud-based file-sharing services provide convenient, easy access to information at any time, anywhere from any device.
However, unless you’re using a secure file sharing service, like Triofox, you still open yourself up to the human error and low-quality encryption that’s easy to breach and exploit.
Risks of Remote File Servers and How to Protect Them
There are three main risks that can be avoided through improved security:
- Releasing Sensitive Data: When you transfer files back and forth, you can intentionally or unintentionally expose sensitive data. Once an unauthorized user gains access to your server, it’s hard to tell how much information was stolen or spread.
- Susceptibility to Invaders: Man-in-the-middle attacks occur when the invader takes control over your firewall. While firewalls are generally good to have, if your file server is poorly encrypted, hackers could easily set up a denial-of-service or ransomware attack.
- Installing Malicious Software: If an employee opens a risky file or link, they could fall victim to a phishing scam or inadvertently download malware, spyware, viruses, Trojan horses, or worms. These viruses could compromise your entire network.
To keep attackers at bay, you’ll need to secure your remote servers from cyber attacks. In the next section, we’ll teach you how to prevent or minimize malicious hacks or internal users.
Steps to Secure Remote File Servers from Cyber Attacks
Securing your remote file servers is the best way to prevent attacks. Here’s how to do it.
- Limit User Privilege: The wider an employee’s portfolio of network access, the greater risk of unauthorized access events. Limit user privilege to limit risks simultaneously.
- Consolidate Files: Your company should keep all of its servers in one centralized location, so you can quickly lock it down if unauthorized access does occur.
- Track File Servers: Micro events, like changing user access and spotting unusual activity, should be monitored to prevent time wasted on locating problems.
- Identify Effective Permissions: Another time-waster involves denial of entry for authorized employees. You may need to individually apply permissions to stay secure.
- Secure Change Management (SCM): SCM practices offer viability across file servers. Introduce this practice to prevent malicious insiders from abusing their admin privileges.
- Name Your Folders: It’s much easier to search for the file in question rather than taking a manual/scanning approach to fine and shut down compromised data or systems.
- Audit Frequently: Be proactive with your auditing by keeping track of your sensitive folders and files weekly. Use a single log to make auditing less time-consuming.
It’s not always easy to keep your files secure, but if you follow our steps, hackers will have a difficult time gaining access to sensitive data from your remote access servers.
Remote File Server Security Best Practices
Companies can manage risks by adhering to best practices for keeping their data and systems secure, even when employees are working outside of the office.
Always Assume Threats Will Occur
Some businesses won’t put security measures in place because they don’t think anyone will ever hack their servers. Although it’s a difficult mindset to acknowledge, accepting that threats can occur at any time will help you be proactive when protecting and encrypting your systems.
Create a Remote Work Policy
It’s important to set clear rules to govern how remote work employees should manage threats. Dictate whether they can use and download apps or tools directly to their personal devices, then explain what the employee can do if they suspect an attack or fall victim to one.
Secure Work Devices
Ideally, employees shouldn’t be using their personal devices when working remotely, and your policy should dictate as such. If possible, provide your employees with specific devices, technology, or practices that can only be used for remote work to prevent security risks.
