OpenDNS Umbrella Network Security Protects Against Ransomware Attacks
With Internet threats, advanced ransomware attacks, and security breaches infecting business networks like never before, OpenDNS Umbrella adds an intelligent, protective layer of security to all your company’s devices that not only blocks these attacks, but also detects unknown threats without adding latency.
What is OpenDNS Umbrella?
OpenDNS Umbrella is not a firewall appliance or end-point antivirus software. Instead, it’s a cloud-delivered network security service that adds an outer layer of content filtering power to your existing secure network—protecting any in-office and mobile devices via clientless DHCP or auto-updated lightweight agents.
Traditional security solutions reroute every Web connection through a proxy, which slows traffic, invades privacy, and can break certain sites. Even then, a large majority of malware, botnet, and phishing threats are hosted at domains or ISPs that are entirely malicious and require no proxy to be blocked.
OpenDNS Umbrella is an improvement on those traditional proxies in that it achieves the security benefits of a pure-proxy solution without degrading the performance or availability of corporate networks by using a DNS layer. Additionally, unlike Web-only solutions, Open DNS Umbrella secures both Web and non-Web connections to detect infected devices that use multi-protocol callbacks to botnet command and control infrastructures—giving you and your devices even more protection from all attacks—especially against ransomware attacks.
Why is protecting against ransomware attacks so important?
In a recent article from Reuters, Mac users downloaded the “KeRanger” ransomeware about 6,500 times before the threat was even detected. KeRanger and other similar ransomeware attacks essentially lock the user out of his or her files so they cannot be accessed. In some cases, the ransomware may demand payment before the files are decrypted and available again for the user. Even this last February, a LA-area hospital paid a ransom of $17,000 dollars to get their critical files back.
Ransomware attacks continue to grow in 2016, hitting banks, businesses, hospitals, and other vulnerable organizations. Luckily, OpenDNS Umbrella gives these businesses and organizations a tool that minimizes the threat of these attacks better than any security solution out there.
Every HTTPS Web post, FTP upload, RTSP video stream, and P2P file share is preceded by a DNS request. With OpenDNS Umbrella, infrastructures hosting malware, botnet, ransomware, or phishing threats are blocked from resolving such requests, keeping attacks from ever reaching OpenDNS Umbrella customers.
