Cybersecurity Recommendations

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 to

xes.

“Nice to have” recommendations to improve your network security

1. Change Passwords Regularly

Regularly change the credentials to your devices to help ensure that only authorized users are

able to access the system.

2. Change Default HTTP and TCP Ports:

● Change default HTTP and TCP ports for systems. These are the two ports used to

communicate and to view video feeds remotely.

● These ports can be changed to any set of numbers between 1025-65535. Avoiding the

default ports reduces the risk of outsiders being able to guess which ports you are using.

3. Enable HTTPS/SSL:

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

devices and recorder.

4. Enable IP Filter:

Enabling your IP lter will prevent everyone, except those with specied IP addresses, from

accessing the system.

5. Change ONVIF Password:

On older IP Camera rmware, the ONVIF password does not change when you change the

system’s credentials. You will need to either update the camera’s firmware to the latest revision

or manually change the ONVIF password.

6. Forward Only Ports You Need:

III

● 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.

7. Disable Auto-Login on Smart PSS:

Those using Smart PSS to view their system and on a computer that is used by multiple people

should disable auto-login. This adds a layer of security to prevent users without the appropriate

credentials from accessing the system.

8. Use a Dierent Username and Password for Smart PSS:

In the event that your social media, bank, email, etc. account is compromised, you would not

want someone collecting those passwords and trying them out on your video surveillance

system. Using a dierent username and password for your security system will make it more

dicult for someone to guess their way into your system.

9. 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.

10. UPnP:

● UPnP will automatically try to forward ports in your router or modem. Normally this would be a

good thing. However, if your system automatically forwards the ports and you leave the

credentials defaulted, you may end up with unwanted visitors.

● If you manually forwarded the HTTP and TCP ports in your router/modem, this feature should

be turned o regardless. Disabling UPnP is recommended when the function is not used in real

applications.

11. 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.

12. 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.

13. Check the Log:

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

the system log. The system log will show you which IP addresses were used to login to your

system and what was accessed.

14. Physically Lock Down the Device:
