How Azure Firewall defends and protects you from ransomware

Azure Firewall Premium acts as an efficient prevention system that protects you from phishing emails with malicious attachments, drive-by download attacks, and other malware-infected elements.

Unresolved vulnerabilities in systems can cause widespread problems, especially now that ransomware attacks are becoming more aggressive every day. Without proper defenses, attackers can penetrate unprotected networks and launch malware. This can mean inconvenience after you realize that you can no longer access your computer system. What's even more disturbing, however, is the ransom you'll need to pay to get everything back to normal. Azure Firewall Premium prevents all this.

Azure Firewall Premium acts as an efficient prevention system that protects you from phishing emails with malicious attachments, drive-by download attacks, and other malware-infected elements. It comes with an Intrusion Detection and Prevention System (IDPS) feature that scrutinizes all packets to detect any malicious activity immediately before it enters your network. It provides you with the maximum ability to monitor your network and provide you with information about it. You can also use Azure Firewall to report it and selectively block it.

Additionally, the firewall has Threat Intelligence (TI) capabilities, and you can enable alert/deny mode to automatically block access to familiar malicious domains and IPs, where the Microsoft Threat Intelligence feed is continuously updated based on emerging threats . For more protection, it is designed to run in default deny mode.

Azure Firewall uses more than 58,000 signatures in more than 50 categories to strengthen security. IDPS signatures apply to application and network level traffic (Layer 4-7) and are updated in real time to continuously protect you against emerging attacks. Azure Firewall releases 30 to 50 new signatures every day, always getting vulnerability information from the Microsoft Active Protection Program (MAPP) and the Microsoft Security Response Center (MSRC) in advance.

On the other hand, if ransomware is installed on a machine, it will use a command and control (C&C) connection to obtain encryption keys from an attacker-hosted C&C server. Until then, however, Azure Firewall Premium will use its hundreds of signatures to detect command and control (C&C) connections to block it and block attempts. In addition, Azure Firewall can inspect encrypted traffic that may carry malware from attackers. It uses its Transport Layer Security (TLS) feature to decrypt and inspect HTTPS traffic, while IDPS scans unencrypted traffic for possible attacks.

Best of all, you can centralize your firewall configuration using Azure Firewall Premium’s firewall policies. It will optimize your protection, prevent risks and provide faster threat action. Here, there is an option to activate Threat Intel and IDPS across multiple firewalls, allow or deny user access to various problematic web categories, or set scoped access to external sites. With these things, Azure Firewall is considered a complete package that can prevent and detect issues that can lead to more serious problems.
