Reverse NS Lookup: Security Against DNS-Based Attacks

Given today’s threat landscape, known threats or those that get publicized are quite hard to protect against. However, risks that come from unknown sources are even harder to detect and block. Domain Name System (DNS)-based attacks fall into the second category for a variety of reasons, the topmost of which is that once domains are up and running, their owners put their security in the background.

There are ways to avoid becoming the next victim of a DNS-based attack, though. One of them is using a reliable reverse name server (NS) solution such as Reverse NS Lookup. But before we delve into further details, let us first discern why attackers take advantage of inherent DNS weaknesses to get to their targets.

How to Use a DNS Archive to Improve Website Traffic, Reputation, and Performance

Infosec professionals are invariably responsible for guaranteeing that their organizations’ websites remain accessible at all times. And so, they should be aware of the consequences of a single website outage. Network downtimes can cost most enterprises between $101,000 and $5,000,000 an hour.

IBM X-force recently reported that the coronavirus went cyber via the Emotet trojan. Rather disgustingly, the miscreants send e-mails to people on behalf of respected health organizations, containing attachments claiming to inform about infection prevention measures. As the victim opens the attachment, it silently installs the trojan on the computer.

How to Find an IP Block Owner with IP Netblocks WHOIS Database

An IP netblock can be a critical piece of information for the companies that engage in online activities. Whether it’s for competitor research or to prevent IP address hijacking, IP netblock data allows technology professionals to deduce who owns a group of IP addresses to pursue their objectives and take relevant action from there.

That said, the ability to quickly derive this information could sometimes spell the difference between success and a missed opportunity, or mitigating or not a cybersecurity threat before it can affect one’s systems and networks.

Knowing a Domain’s Ownership History Can Help You Avoid Getting a Blacklisted Domain

When starting an online business or marketing campaign to reach out to more people, one of the most critical tasks is deciding on what domain name to use. You can’t just choose one on a whim — you need to put a lot of thought and research into it as your domain will carry your brand.
