Types of DNS Attacks and How Application Monitoring Can Help

DNS, the Domain Name Service, is the Internet service that translates IP addresses into hostnames, and visa versa. It enables you to type www.exoprise.com in a browser, or send an email to someone at that domain, and have your request actually go to 35.172.52.247. As a vital part of the Internet infrastructure, DNS attacks can have a serious impact on your online operations, including access to your website and email.

DNS Hijacking: What You Need to Know

Crashed websites and slow loading pages can be devastating for any site owner. But there’s another type of threat that often goes undetected. A report published by FireEye on Thursday details a particular type of DNS hijacking that allows hackers to easily steal information. These attacks have been going on for approximately two years and involve three different methods that compromise websites without alarming users.

Dynamic DNS & Falco: detecting unexpected network activity

Since the inception of Falco, we’ve seen users write custom rules covering a number of different use cases. Because Falco is behavioral monitoring with a syntax that leverages system calls, you can write a rule for just about anything: opening a file, becoming root, or making a network connection.

Monitoring DNS Records for Wildcard Values

Back in 2016, we added support for monitoring wildcard DNS records. Wildcard DNS records are used to serve requests for otherwise non-existent domain names. Today we’re pleased to announce that we’ve extended our support for using wildcards in DNS records monitoring. DNS Check now allows you to specify a wildcard (*) in place of some DNS record values, such as an A record’s IP address to indicate that any value is acceptable, but the record must exist.

Feature Spotlight: DNS Checks

The Domain Name System (DNS) is brilliantly designed as a hierarchical structure, ensuring that any single point can fail with the system remaining relatively intact. There are some nuances to this statement, like caching issues that arise from outages, but the overall focus is on uptime. This is why the DNS check is a critical part of your IT uptime monitoring process.

DNS in the Cloud- Solid or Not?

The Domain Name System (DNS) catalog maps text-based URLs to their specifically-numbered host systems. As the phone book or Yellow Pages of the internet, DNS governs the speed with which websites and online resources may be located, so the speed and robustness of your DNS service can have a profound impact on your internet performance overall.
