Hikvision on Fundamentals to Address Cybersecurity Concerns

 

Understanding cybersecurity concerns and how to protect against them is important as hackers shift their attention to SMBs. The Security magazine article, “Tips small businesses can use to strengthen their cyber health,” offers several ways small businesses can reduce vulnerabilities and risk of breach.

Twenty-eight percent of security breaches involved small businesses, according to the Verizon Data Breach Investigations Report, making it critical that these organizations learn how to protect their networks and data.

From the article: “While cyberattacks targeting large corporations or government agencies tend to make splashy headlines, the truth is that many attackers are shifting their priorities to focus on small businesses. Unfortunately, these smaller businesses generally lack the resources and security capabilities of larger organizations. In fact, 83 percent of small business owners report handling cybersecurity matters themselves.”

Many breaches involve attacks using stolen credentials that were acquired through phishing or other cyberattack methods. Granting access to users only based on their role and daily responsibilities can reduce this risk. The article added: “Finding and remediating these exposed credentials before attackers identify and exploit them is essential. Businesses can turn the situation to their advantage by seeding their networks with deceptive credentials that trick intruders into exposing themselves.”

Ransomware threats are also growing. Ransomware quietly encrypts all the files and folders on your computer, and any data on connected USB or mounted shared drives, and then uploads the decryption key to the threat actor who tricked you into installing the ransomware. You will then see a screen show up on your computer that informs you that your data is encrypted. To get the key to decrypt your files, you must pay a ransom to the threat actor. Boosting in-network protections can boost security in the face of ransomware threats.

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.
