Automatisation S.P MyIP

Nmap, which stands for “Network Mapper,” is an open source tool that lets you perform scans on local and remote networks. Nmap is very powerful when it comes to discovering network protocols, scanning open ports, detecting operating systems running on remote machines, etc. The tool is used by network administrators to inventory network devices, monitor remote host status, save the scan results for later use, and so on.

The Nmap suite includes an advanced graphical user interface and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).

Cybercriminals actively target vulnerable IP addresses to host malware and conduct illegal activity they don’t want traced back. When cybercriminals use an IP address for malicious activity, it may be put on a blacklist. Regularly conducting IP reputation checks can help organizations prevent further reputation loss and speed up the time-to-detection in the event of a cybersecurity incident.

WHAT IMPACT DOES MY IP REPUTATION HAVE ON CYBERSECURITY?

IP reputations determine whether digital communications from your organization will end up on an email blacklist, or make it past the spam email filter. Email service providers analyze numerous factors, and the trustworthiness of digital communication efforts rely substantially on the cleanliness of your IP address. Excess spam flags may have a negative impact on both your sales and marketing email campaigns, as well as your organization itself.

Even more importantly, blacklisted IPs may also indicate security concerns. Sixty percent of companies receive a “C” or lower grade in IP reputation. Alarmingly, even beginner-level threat actors can breach vulnerable network IPs for target practice. The IP address can be exploited for malicious use without the victim even knowing.

5 STEPS TO IMPROVE YOUR IP REPUTATION

1. Proactively monitor your cyber risk posture and look into reputation vulnerabilities.
2. Ask reputation and content filtering sites to properly categorize your website.
3. Block unexpected/ malicious traffic on the firewall.
4. Change the default resolving IP address of all domains to a whitelisted IP or a loopback IP.
5. Avoid using shared services, or IP addresses used by other domains, wherever possible.

WHY WAS MY IP BLACKLISTED?

An IP address is blacklisted when suspicious activity is detected. IPs may be blacklisted for a variety of reasons, including a high number of failed login attempts to your control panel within a short period of time. You may think it is a result of personal password attempts, but it could very well be a cybercriminal trying to breach your data.

While employees are sometimes behind suspicious online behavior, cybercriminals are often the ones responsible for poor IP reputation. Although blacklist status is often temporary, it’s important to remain aware of the cyber risk associated with blacklisted IP addresses.
