Cybersecurity Recommendations I

Cybersecurity Recommendaons

Mandatory actions to be taken towards cybersecurity

1. Change Passwords and Use Strong Passwords:

The number one reason systems get “hacked” is due to having weak or default passwords. It is

recommended to change default passwords immediately and choose a strong password whenever

possible. A strong password should be made up of at least 8 characters and a combination of special

characters, numbers, and upper and lower case letters.

2. Update Firmware

As is standard procedure in the tech-industry, we recommend keeping NVR, DVR, and IP camera

rmware up- -date to ensure the system is current with the latest security patches and fixes. to

“Nice to have” recommendations to improve your network security

1. Enable HTTPS/SSL:

Set up an SSL Certicate to enable HTTPS. This will encrypt all communication between your devices

and recorder.

2. Forward Only Ports You Need:

● Only forward the HTTP and TCP ports that you need to use. Do not forward a huge range of numbers

to the device. Do not DMZ the device's IP address.

● You do not need to forward any ports for individual cameras if they are all connected to a recorder on

site; just the NVR is needed.

3. Limit Features of Guest Accounts:

If your system is set up for multiple users, ensure that each user only has rights to features and functions

they need to use to perform their job.

4. SNMP:

Disable SNMP if you are not using it. If you are using SNMP, you should do so only temporarily, for

tracing and testing purposes only.

5. Multicast:

Multicast is used to share video streams between two recorders. Currently there are no known issues

involving Multicast, but if you are not using this feature, deactivation can enhance your network security.

6. Check the Log:

If you suspect that someone has gained unauthorized access to your system, you can check the system

log. The system log will show you which IP addresses were used to login to your system and what was

accessed.

7. Physically Lock Down the Device:

Ideally, you want to prevent any unauthorized physical access to your system. The best way to achieve

this is to install the recorder in a lockbox, locking server rack, or in a room that is behind a lock and key.
