DDoS Attacks
Excessive traffic can overwhelm RDP servers, disrupting remote access. Restricting RDP access and configuring firewalls helps block these attacks. Trusted providers go further, adding DDoS protection to detect and block DDoS and brute-force attacks dynamically.
Inadequate Access Control
Unlimited root access, unused accounts, and poor permissions can lead to unauthorized access. Apply least privilege, disable inactive accounts, and regularly review root and user permissions to secure your server.
Lack of Multi-Factor Authentication (MFA)
Adding layers like OTP and biometrics to your login process strengthens security, making it much harder for hackers to succeed in brute force or phishing attacks.
Phishing and Social Engineering
If a hacker deceives you into sharing your login details via a fake link or email, the phishing attack succeeds. To safeguard against this, it’s vital to raise awareness and educate yourself and your team on how to avoid phishing threats.
Top Strategies to Secure Remote Access
RDP security best practices create layered defenses, ensuring a secure remote connection:
Account and authentication
Use strong, unique passwords: Make passwords at least 10 characters long with a mix of uppercase, lowercase, numbers, and symbols (e.g., Xpj*V7+39B%iQWJ). Avoid using easily guessable personal or company info.
Password management: Store and manage passwords securely with a trusted password manager like 1Password or LastPass. Never reuse passwords across accounts.
Regularly update passwords: Change passwords periodically and avoid sharing them with others.
Enable Multi-Factor Authentication (MFA): Use additional authentication methods, such as one-time passcodes from apps (e.g., Google Authenticator) or biometric authentication (e.g., fingerprint or facial recognition).
Activate certificate-based authentication: Enable methods like NLA (Network Level Authentication) to secure login access.
Set account lockout policies: Limit failed login attempts to prevent brute force attacks, but ensure thresholds are set reasonably to avoid accidental lockouts.
To fully secure your RDP login process, choose an RDP server from a provider that complies with security standards and offers root access. Also, with expert support, you can ensure your security measures are optimized for maximum protection.

Device and software security
Keep RDP server updated: Ensure RDP server software, hardware, and network infrastructure are always up to date.
Update OS for all devices: Keep operating systems up to date with the latest security patches to protect against known vulnerabilities.
Regular app updates: Update all applications, especially the RDP client, browsers, drivers, and system software.
Use supported apps: Install vendor-supported applications and ensure they are not end-of-life (EOL) to avoid security issues.
Disable unused services: Remove or disable unused services and apps to reduce potential attack surfaces.
Use endpoint protection: Ensure all devices have antivirus, anti-malware, and firewall software installed and up to date.
Limit user access (PoLP - Principle of Least Privilege): Restrict user permissions to the minimum necessary to perform their duties.
Configure firewalls correctly: Set up local firewalls on all devices in accordance with best-practice security standards.
Implement MDM for mobile devices: Use Mobile Device Management (MDM) to configure and remotely manage mobile devices securely.

Connection and network
Use a VPN: A VPN encrypts connections between remote devices and company servers, adding an extra layer of security to protect data from unauthorized access.
Use RDP Gateways: RDP Gateways securely manage and process RDP requests, acting as intermediaries before granting access to internal resources.
Avoid public Wi-Fi: Always connect through trusted networks or cellular data to prevent interception and mitigate man-in-the-middle attacks.
Update your router: Regularly update your router’s firmware and enable features such as IDS, firewalls, and encryption to close security gaps and enhance network security.
Segment your network: Network segmentation ensures that if one area is compromised, the rest remain secure. Use firewalls, VLANs, and software-defined perimeters to enforce this.
Restrict direct RDP access from external networks: Prevent unauthorized access by configuring a VPN, setting IP and user account access lists, enabling NLA, requiring MFA, and restricting RDP ports.
Change the RDP port number: Change the default RDP port (3389) to an unconventional one to reduce the risk of automated attacks and port scans.
OperaVPS also adds advanced security features, such as DDoS protection and external firewalls, ensuring strong security and uninterrupted remote access.

Additional best practices
To achieve the most secure remote access for businesses relying on remote communication, combine the following expert solutions:
Perform continuous auditing
Reviewing login logs, user activity, server configurations, and resource usage helps quickly detect anomalies and vulnerabilities. This enables rapid response to emerging threats, effectively securing your network.
Conduct risk assessments
Excessive permissions, inactive accounts, too many admin accounts, unused services, and weak configurations pose a risk to remote access security. Regular audits and risk assessments are key to promptly identifying and fixing vulnerabilities.
Use secure protocols
According to ScreenConnect and NordLayer, using secure protocols like SSH with key-based authentication instead of passwords significantly reduces the risk of brute-force and password-spraying attacks. Additionally, SSL/TLS certificates secure remote connections, enhancing the safety of remote communication.

Train employees
Regularly updating your employees' awareness of cyberattacks, security policies, and network vulnerabilities significantly reduces human error, accelerates remediation of vulnerabilities, and strengthens RDP security.
Remote access security protocols should cover:
● Enabling multi-layered authentication
● Care and sensitivity in sharing RDP credentials
● Identifying phishing threats and how to mitigate them
● Ensuring complete logoff, not just disconnecting, to maintain security
● Reviewing past remote access breaches to pinpoint causes, exploits, and impacts
📌Here are two real-world cyberattacks:
NetWalker Ransomware Attack (2020): Phishing attacks targeted organizations, using software vulnerabilities to steal sensitive data and demand ransom.
Colonial Pipeline Attack (2021): Hackers shut down U.S. fuel supplies by exploiting security weaknesses in energy management systems.
A Checklist to Enhanced RDP Security
✅Use RDP server with updated software, robust security (DDoS protection and firewall), and full root access.
✅Mandate MFA for all users alongside basic password login.
✅Encrypt remote connections using VPN with TLS/SSL.
✅Configure internal and external firewalls.
✅Adhere to the PoLP rule and grant each user sufficient access.
✅Use IDS/IPS to detect and block potential RDP attacks in real time.
✅Set Session Timeout to auto-terminate inactive accounts.
✅Constantly update the software versions used on the RDP server.
✅Minimize the number of users with RDP access, even admins.
✅Restrict account usage based on time or location.
✅Protect RDP ports by using a proxy server.
✅Segment the network to isolate and protect against unauthorized access.
✅Use Session Recording to track and record user activity.
✅Set policies to detect suspicious RDP activity.
