Hikvision Cybersecurity Director Offers Tips to Reduce Cyber Attacks and Security Concerns in Network Security, User Security and System Administration

Cybersecurity Tips from Hikvision to Reduce Security Concerns

 

Hikvision’s director of cybersecurity, Chuck Davis, offers insights to help reduce security concerns in video surveillance, access control and integrated solutions.

Davis, together with the Hikvision Security Lab at Hikvision headquarters, is leading the cybersecurity program for Hikvision North America, overseeing all internal and external cybersecurity initiatives and programs in the region.

Examples of ‘Defense in Depth’ and Other Key Steps for Security 
Davis advocates the practice of "defense in depth," an approach to manage risk using diverse defensive strategies. It’s based on the idea that multiple layers of defense will provide additional protection against a potential cyberattack. This includes network segmentation, which simply stated means splitting a network into separate networks that are isolated, not connected, and compromising one won’t compromise the others. For example, finance, human resources and security should each have dedicated networks.  

“This is the way corporate networks are built, which is based on the principle of least privilege – this means only giving people or systems access to the resources that they need, and nothing more. This is effective for the obvious reason of keeping sensitive resources only accessible by those who need access, but it is also an effective means of compartmentalizing a network environment in case of cyberattack or malware infection,” says Davis.

Here, Davis offers high-level steps to secure different areas of your network:

  • Examples of Security for System Administration:
  1. Inventory: One of the most important things you can do is to be aware of what is on your network so you can determine if something new shows up.
  2. Patching: Be sure to patch regularly. Vendors find vulnerabilities and create patches all the time. Ensure you have a process in place to update systems with security patches, the same way you update your servers, laptops/desktops and mobile devices.
     
  • How to Improve Network Security:
  1. Place devices behind firewalls to protect them from untrusted networks, such as the Internet.
  2. Network segmentation should be used to separate security networks from other networks (HR on one network, finance on another network, and security on yet another network).
  3. Where possible, use virtual private networks (VPN) to remotely connect to your secured network from the Internet.
  4. If you have the resources, install a network intrusion detection device to alert you to anything anomalous happening on your network.
  5. Run vulnerability scans against the devices on your network to alert you of new vulnerabilities.
     
  • How to Improve User Security:
  1. Always change default user ID and password credentials.
  2. Be sure that each user has their own user account.
  3. Be sure that users only have access to resources they need. Don’t make everyone an administrator (principle of least privilege, again)
  4. Do not re-use passwords.
  5. Create strong passwords.
     

How To Protect Passwords and IoT Devices
Changing default passwords to complex passwords is a simple, yet critical step to bolster security. In a recent video interview with Campus Safety magazine on May 30, 2018, Davis said: “Defaults are really bad. Hackers love to focus on defaults because they realize a lot of people don’t change defaults, whether it’s default passwords or ports or different configurations. So, always make sure you’re changing those defaults."

In an earlier Campus Safety interview posted on April 16, 2018, Hikvision’s Davis said: “Video surveillance systems, just like all systems that are part of the Internet of Things (IoT), are actually computers. So we tend to forget that all of these devices that we’re connecting to our IP networks, [which are]  ... adding all this great functionality to allow us to remotely monitor or control them, are actually computers. They have operating systems and they will have vulnerabilities. And so if we don’t take our proper due diligence and protect those things and really apply cybersecurity best practices, we put them at risk of being attacked …”

IMPORTANT! This model requires non-standard firmware. Do Not Install standard firmware (e.g. v.4.1.xx) on this model. Doing so will permanently damage your system. You must use custom firmware v.4.1.25 from the iDS-9632NXI-I8/16S product page.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.

 

Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.

 

After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.

 

Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.

 

Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.

 

Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.

 

Downgrading

Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.

K-Series DVR upgrade instruction
The Turbo 4 Hybrid DVR K series has multiple models and across different platform and chipset. It also has similar firmware development of other recording product line; DVR K series has also introduced the GUI4.0 to ensure the series to be compatible to the newest technology available. The new database architecture is also brought into the DVR firmware v4.0 to be future proof and for better recording search experience. 
 


Database Optimization and Repair

As more affordable cameras introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.
After upgrading to v4.X, the recorder database will need to be converted and optimize. If you are experiencing issues, where playback is expected but not found, please make sure to perform "Database Rebuild" as indicated in the procedures and scenarios below.
 


Preparing the Upgrade

Before proceeding with upgrade, it is recommend exporting DVR configuration file from the DVR over the network or on to a local USB drive.

 

Action after firmware upgraded 

1. Upgrade the DVR according to the chart above. 

2. Reconfirming Channel's Recording Schedule 

    - Confirm channel's recording schedule is enable. 

    - Check if the channel is on correct recording schedule.

3. Double Check Storage Setting

    - Make sure all channel are assigned to record on its HDD group when the Storage setting is under Group Mode. 

4. Perform Database Rebuild locally. 

    • Some version above support Database Rebuild via web access - K51 and K72

    • Perform Database Rebuild regardless if system is having any database issue symptom. 

    • Database Rebuild process is average ~30 to 60min per TB. The process may still varies depends recording data.

    • After Database Rebuild - Check log to confirm Database Rebuild has went thru properly. 

    • If Database Rebuild Started and Stopped log has been log only within few minutes. Database rebuild may not has been completed properly. It is strongly recommend performing the Database Rebuild again.

    • To check log > System > Log > Information > Database Rebuild Started and Stopped.

    • If the log option is not available - access system via SSH can also obtain similar result.

5. Recording Data is still missing after database rebuild process. 

If the data has not been recorded or has been overwritten, Database rebuild process is not able retrieve those lost data. Have the system upgraded to the latest available firmware version above to prevent any future data lost is strongly recommended for all application.
