Hikvision Senior Director of Cybersecurity on Using Zero Trust Network to Address Security Concerns

 

SecurityInfoWatch.com (SIW) covers Zero Trust to combat vulnerabilities and reduce hacks in this article: “Five key considerations for tackling Zero Trust.” Zero Trust is an approach to network security aimed at safeguarding data and maximizing cybersecurity.

From the article: “In the time of COVID-19, many companies’ biggest risk may be associated with data that is contained in email. As digital communications seem to be favored over phone conversations, all companies need to be sure they have a policy in place that ensures confidential data is being protected whether it’s shared from corporate laptops or personal devices that have been called into duty due to remote working conditions.”

The article outlined key Zero Trust considerations, which included:

  1. Data being created today has a higher value, and therefore risk, than older information or archived data. This makes current data the most critical to protect first.
     
  2. Understanding the lifecycle of the data in order to create a policy for people to follow.
     
  3. Identifying the highest value data to start with.

Hikvision’s senior director of cybersecurity, Chuck Davis, also covered Zero Trust Network architecture in a recent SIW article. In it, Davis said: “So how do you defend against this (network cyberattacks)? There is an architecture, called the Zero Trust Network, that treats the internal network of an organization as a hostile environment by trusting no one. Created in 2010 by John Kindervag, the former principal analyst at Forrester Research, the Zero Trust Network is based on the concept that all company internal networks are not trustworthy and should be treated as untrusted. Access is only given to devices that need to communicate with each other.”

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.
