Many people are using Microsoft Remote Desktop Connection to work from home and remotely login to the server at the office. This is especially true for those who are using Accounting software such as AutoCount, SQL Account, and UBS and others.
This can be very risky as Microsoft Remote Desktop Protocol (RDP) is notorious for suffering from brute force attacks, guessing of your username and password by robots. When the attempt to obtain the user credential of the remote desktop or server is successful, the hacker can gain access to the desktop or server, and move laterally from there and disrupt your business by encrypting the data and files in your PC or Server, to cause business-threatening downtime, so they can blackmail you into paying them to decrypt your data and files.
Furthermore RDP has been hit by various security vulnerabilities over the years. Most significantly, a bug by the name of BlueKeep which arose in 2019 was allowing cybercriminals to remotely take over a connected PC that’s not patched.
To keep your network and server safe from hackers, RDP users need to do some basic security checks below:
1.Do NOT use easy-to-guess username and password, such as user1 and dictionary words.
2. Implement Account Lock-out Policy. Lock down the account for 30 minutes or longer once there are 3 failed attempts.
3. Do NOT allow RDP port exposed to the public internet. This may require VPN or equivalent so that even if you are using RDP, no RDP port is actually exposed. An exposed RDP port is essentially telling the cybercriminal the address of your home and inviting them for brute force attack. Nowadays, network software is widely available which enables any bad actor to sweep the 3.7 billion IP addresses and their ports in less than 10 minutes.
Secure your network connection is as important as having your data and files tightly protected with Offline Backup with multiple copies or snapshots of your backup. Virtual Local Network (VLN) is similar to VPN, providing a secure network connection between your home and the office as if everyone is working under the same roof.
