DNS Security
Disrupt DNS Attacks and boost your cyber readiness
Why does DNS Security matter?
DNS security is one of the most critical cyber security areas for organizations. The term refers to secure and control measures that involve DNS protocol. The solutions provide a critical layer of safeguard capability by filtering out malicious behavior involved with DNS. Traditionally DNS protocol has not been designed a security-by-design approach.
According to IDC's 2021 Global DNS Threat Report, 87% of organizations were victims of DNS-based attacks. Palo Alto Networks Unit 42 Threat Research says 85% of malware uses DNS to establish a command-and-control channel that allows attackers a safe path to exfiltrate data. DNS has mostly been unencrypted. Many of today's emerging threats depend on DNS activity. Malware, ransomware, botnets, phishing attacks leveraged DNS misconfigurations and vulnerabilities to orchestrate each stage of the kill chain. High-profile attacks advertised DNS beaconing and DGA techniques, just like in popular SUNBURST attack, threat actors often leveraged DNS tunneling for data exfiltration.
Ensuring the detection of anomalous and malicious DNS activity can provide better visibility, security effectiveness, and detection capability of adversary behavior that provide a better triage window for compromised systems and improve cyber readiness. So, are you ready to secure your DNS?
Disrupt Today's Most Sophisticated DNS-Based Attacks
Today's most security teams often lack visibility into how attackers utilize DNS. Traditional strategies lack automation and visibility, resulting in underutilized security investments that can never provide insights into threats and deliver full security visibility into malicious DNS traffic.
Palo Alto Networks DNS Security service continuously identifies threats hidden in DNS traffic by Palo Alto Networks threat intelligence and machine learning. The service uses predictive analytics to disrupt attacks that use DNS for (C2) or data exfiltration. Native integration with Palo Alto (NGFWs) provides automated protection and eliminates the necessity for disconnected tools.
Today's sophisticated DNS-layer attacks and data exfiltration techniques require ML algorithms that can analyze DNS traffic. It also requires vital threat intelligence insight to utilize those algorithms and take necessary actions to protect the business against specific attack techniques. Ultimately, it requires blocking sinkhole malicious DNS activity once identified and providing full visibility into their DNS traffic through the Autofocus contextual threat intelligence service.
Palo Alto Networks is collecting and attributing data from a multitude of sources, including WildFire traffic analysis, passive DNS, active web crawling & malicious web content analysis, URL sandbox analysis, Honeynet, DGA reverse engineering, telemetry data, whois, the Unit 42 research organization, and third-party data sources. Such as the Cyber Threat Alliance with access to the complete Palo Alto Network's DNS signature set including real-time DNS request analysis.
An organization's online presence is critical, whether you have an eCommerce site, service portal, gaming server, or SaaS application, your business is defined by the user experience and reliability you give your customers. In a connected world where customers expect flawless and secure online experiences, DNS has evolved into more difficult and trickier to manage than ever before. Sophisticated threats leave security teams hard to find the correct DNS strategy while keeping all assets up and securely running.
Vercara (Formerly Neustar Security Services) UltraDNS is an enterprise-grade, cloud-based authoritative, and recursive DNS service that securely delivers fast and accurate query responses to internet applications. Since DNS is fundamental to every aspect of today's organizations, it's important to choose the right service provider that is fully committed to ensuring flawless execution of every query despite complexities, challenges, and threats.
You cannot afford poor performance in your DNS service. Ensure the fastest response to every DNS query is delivered to users and customers. Purpose-built network based on DNS expertise. A DNS provider should prioritize and filter traffic to improve efficiency; they must respond immediately to every request. Response time can't be adjusted based on high traffic loads or malicious activity. Every response to every query must be immediate, every time.
Vercara has specialized in security for more than 20 years. The UltraDNS platform is supported by a DDoS mitigation platform that provides dedicated data scrubbing networks in the world, with a capacity of more than 15+ Tbps. The Vercara security operations center (SOC) ingests sophisticated threat feeds, analyzes emerging cyber threats across the World., and stops attacks as a matter of daily routine.
Why does it matter? More than 80%+ of all cyber-attacks are deployed via DNS 72% of organizations experienced a DNS attack in the last 12 months Security is as critical for managed services as for on-premise DNS There are two reasons that DNS draws the attention of adversaries: it is a ubiquitous core technology of the internet, and it was poorly designed for security protection. For these reasons, it has become a common and attractive attack vector and target for bad actors.
