Cybersecurity Recommendations VII

Cybersecurity Recommendations

Mandatory actions to be taken towards cybersecurity

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.

Update Firmware

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

and IP camera firmware up-to-date to ensure the system is current with the latest

security patches and fixes.

Recommendations to improve your network security

Change Passwords Regularly

The length should be greater than 8 characters;

Include at least two types of characters; character types include upper and lower case

letters, numbers, and symbols;

Do not use an account name or the account name in reverse order;

Do not use sequential characters, such as 123, abc, etc.;

Do not use repeated characters, such as 111, aaa, etc.;

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 and 65535.

Avoiding the default ports reduces the risk of outsiders being able to guess which

ports you are using.

Update Firmware and Client Software

Keep your network-enabled equipment (such as NVRs, DVRs, IP cameras, etc.)

firmware up-to-date to ensure the system is equipped with the latest security patches

and fixes. When the equipment is connected to the public network, it is recommended

to enable the “auto-check for updates” function to obtain timely information of firmware

updates released by the manufacturer.

Download and use the latest version of client software.

Enable HTTPS/SSL

Set up an SSL Certificate and enable HTTPS to encrypt all communication between

your devices and recorder.

Enable IP Filter

Enable the IP filter to prevent unauthorized access to the system.

Cybersecurity Recommendations VIII

Change ONVIF Password

Older IP camera firmware does not automatically change the ONVIF password when

the system credentials are changed. Update the camera’s firmware to the latest

revision or manually change the ONVIF password.

Forward Only Ports You Need

Forward only the HTTP and TCP ports that are requited. Do not forward a wide range

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

Do not forward any ports for individual cameras if they are all connected to a recorder

on site. Simply forward the NVR port.

Disable Auto-Login on SmartPSS

Disable the Auto-Login feature on SmartPSS installed on a computer that is used by

multiple people. Disabling auto-login prevents users without the appropriate

credentials from accessing the system.

Use a Different Username and Password for SmartPSS

Do not a username/password combination that you have in use for other accounts,

including social media, bank account, or email in case the account is compromised.

Use a different username and password for your security system to make it difficult for

an unauthorized user to gain access to the IP system.

Limit Features of Guest Accounts

Ensure that each user has rights to features and functions they need to perform their

job.

Disable Unnecessary Services and Choose Secure Modes

Turn off specific services, such as SNMP, SMTP, and UPnP, to reduce network

compromise from unused services.

It is recommended to use safe modes, including but not limited to the following

services:

SNMP: Choose SNMP v3 and set up strong encryption passwords and authentication

passwords.

SMTP: Choose TLS to access a mailbox server.

FTP: Choose SFTP and use strong passwords.

AP hotspot: Choose WPA2-PSK encryption mode and use strong passwords.

Multicast

Multicast is used to share video streams between two recorders. Currently there are

no known issues involving Multicast. Deactivate this feature if not in use to enhance

network security.

Check the Log

The information stored in the network log file is limited due to the equipment’s limited

storage capacity. Enable the network log function to ensure that the critical logs are

synchronized to the network log server if saving log files is required.

Check the system log if you suspect that someone has gained unauthorized access to

the system. The system log shows the IP addresses used to login to the system and

the devices accessed.

Physically Lock Down the Device

Perform physical protection to equipment, especially storage devices. For example,

place the equipment in a special computer room and cabinet, and implement access

control permission and key management to prevent unauthorized personnel from

accessing the equipment.

Cybersecurity Recommendations IX

Connect IP Cameras to the PoE Ports on the Back of an NVR

Cameras connected to the PoE ports on the back of an NVR are isolated from the

outside world and cannot be accessed directly.

Isolate NVR and IP Camera Network

Ensure that the network for the NVR and IP cameras should not be the same network

as a public computer network. Separate networks prevent unauthorized users

accessing the same network the security system.

Secure Auditing

Check online users regularly to ensure unauthorized accounts are not logged in to a

device.

Check the equipment log to access the IP addresses used to login to devices and

their key operations.
