#Stop brute force port attack meraki password

Once you have a connection that is found to be open and access is gained through a brute force password attack, the attacker now has free rein over that device and anything connected to it. We have even found through our own research that most administrative passwords commonly contain a derivative of the company name which can narrow down the guessing.Д«y combining weak password policies with open RDP connections, you risk a quick and simple attack on your network. Many IT departments still use common passwords for end users with a little flare such as Welcome1, Password1!, etc.

Software bought off the shelf or downloaded for free can be used to quickly attempt logins using common usernames and passwords. The process to brute force your way into a network using passwords is quite simple. Often times, the Administrator passwords can also be guessed.

This means that the entire security of the network is reliant on the security of the passwords attached. Once an RDP port is detected to be opened, criminals can then attempt to brute force their way into the computer by guessing the passwords. The only way to secure your RDP connections is to close the hole in your firewall, and if it is needed, to use a front-end device, which will be discuss later. Through their research, Sophos uncovered that some of the scanned devices were found to be open in under two minutes, just right after being put online! You cannot place a server with an open RDP on the internet for even a minute to test. Take into consideration the evidence obtained from Sophos. You must be aware that your networks are constantly being scanned for open ports from people and computers all over the world. Once the ports are open, attackers can then attempt to gain access.

However, as with all things that are useful, they can be used against you. There is a legitimate need for the process of port scanning, which is why it is technically possible. This technique is very old and will likely continue until the end of time. Port Scanning is the process of scanning IP addresses to see which ports are open. Once the firewall policy is written to allow traffic to pass through, the overall use of the firewall is pointless. There are a surprisingly high number of RDP connections open to the public that typically sit behind a firewall. Throughout this article, I aim to break down the major issues that exist while using RDP to access a device remotely.

As administrators race to patch for that vulnerability, there is an even greater vulnerability that exists within the use of RDP. The recent issue has to do with a piece of malware known as BlueKeep (CVE- 2019-0708). The problem with RDP is its susceptibility to abuse and that it can be a launchpad for an infection or hacking within your network.

This protocol is heavily relied on and widely deployed. Remote Desktop Protocol, commonly referred to as RDP, is a way for users to access Windows devices remotely as if they were locally sitting in front of a computer screen. Research for this article relied heavily on the fascinating report from Sophos Labs.
