CCTV camera installation is low cost and easy these days. Connecting CCTV (closed circuit television) systems to the Internet is quite popular nowadays, it offers the user the capacity to see and also control their CCTV systems remotely. Nevertheless, there is exist a very high amount of internet connected devices vulnerable to attack, whether pre-meditated, or just using automated ‘bots’. Such attacks may make a CCTV system ineffective by possibly corruptible or deleting the settings, removing video recordings, or even stopping access to the device. They are able to furthermore be used to trigger damage to various other devices which are connected to the CCTV system.

I will emphasize certain prospective vulnerabilities, and give you simple steps to reduce the chances of your CCTV systems being attacked. The reason why are Internet connected CCTV systems is attacked? It will be unlikely that a hacker as well as bot really wants to attack any CCTV system in any respect, they are much likely searching for internet servers as well as file servers that they will have access to.
However, latest IP connected CCTV systems frequently have internet servers as well as file servers integrated within them which can be used to configure the system by using website pages, images, display video or download archived video footage.
Therefore, regardless that your CCTV system might not be a major target for a bot, it may still undertake some severe damage to your system as long as they can get access to it. Exactly how vulnerable are Internet connected CCTV systems? There are numerous reasons a CCTV system can be vulnerable to an attack. The commonest being:
The device responds to Ping requirements. It’s using common IP socket ports like port 21 (FTP), and port 23 (Telnet), port 80 (HTTP), as well as the default ports. A poor strength password will be used, or even the password is not also been changed from the manufacturer’s default. Hence the system is accessible to connection from virtually any source. There could actually be vulnerabilities within the DVR software/firmware.
This isn’t a comprehensive list, however the commonest are the reason why internet connected CCTV systems are vulnerable. How can I render my Internet connected CCTV systems considerably less vulnerable? First and foremost, it is worthwhile addressing every one of the points above to see whether there are instant problems which may be resolved:
Ping is a technique used to detect whether or not an IP device is connected to the internet. Hence be very careful and make sure the CCTV system does not respond to any Ping requests. When the DVR or the router which is connected and respond to any Ping requests, it may well signal any potential attackers to your system or device which is available to attack. Switch off Ping response in the Router as well as DVR to avoid this from occurring.
Modify the IP port which is used currently to gain access to the unit over the Internet – When the DVR is using port 21, 23, as well as 80, check if these may be changed on the DVR by itself. If it is not possible, change the router configurations or settings to use Port Forwarding, to ensure that web traffic on a particular entering port number will probably be forwarded to the proper port of the DVR on the system or network. For instance, you may forward any kind of web traffic on port 3080 to DVR on port 80, as a result almost any external connection to the IP address on port 3080 could possibly get through, however the connections to port 80 cannot.
There are even more techniques of improving security of your own Internet connected CCTV systems which may be way beyond the remit of this, however by applying these few simple measures, you may as well reduce the chances of your CCTV system being attacked.
