Vulnerabilities that Enable Security

Hikvision Covers Malware, Ways to Reduce Security Concerns

 

The Security magazine article, “Three Reasons Cybercriminals Continue to Succeed in Breaching Some of the Biggest Brands,” highlights the risk of security breach and several conditions that enable a successful breach.

From the article: “With the average data [security] breach costing enterprises $1.23 million and fines in the billions now at stake, security professionals, like chief information security officers (CISOs) and business leaders need to band together to align their strategies and budgets with the protection needed to stand up to today’s evolving cyber threats.”

Security breaches cannot be avoided, but understanding some of the risk factors can help organizations mitigate risk. The article references a recent Kaspersky Lab study where 86 percent of CISOs believed that breaches were inevitable.

 

Digital Transformation and Other Risks

A few trends can widen organizational risk for cyber threats, including digital transformation which gives “cybercriminals more opportunities to find weaknesses to creep into systems and leak or exploit data,” according to the article. Cloud adoption and a growth in the mobile workforce are also cyber risk factors. Internal threats also pose a risk: “What if a malicious insider–an employee perhaps–was to single-handedly work against a company or even combine their efforts with those of an external attacker? To help them through the backdoor, so to speak.”

 

Prioritizing Cybersecurity Budgets

CISOs are facing budget challenges to fight cybercrime, according to the Kapersky Lab study, leading to increased risk.

The article cites a few reasons that security budgets aren’t being properly allocated:

  • They become part of wider IT budgets where priorities are reserved for cloud or other IT initiatives.
  • CISO’s find it difficult to get funding approved since they are often not able to guarantee a security breach will not occur.

 

Asking Questions to Identify Cyber Needs

Cyberattacks happen, so organizations need to determine if they can quickly identify an attack and respond to reduce its impact, according to the article. Asking the right questions when planning or allocating budgets can help. A recommended question for organizations to ask is: How will the money be used to prevent and detect cyberattacks early on?

The article added that “the CISO’s strategy for security needs to be supported by business leaders, otherwise the security team can’t take immediate action when cybercriminals make attempts to interfere with the organizations’ network.”

Hikvision Covers Malware, Ways to Reduce Security Concerns

In a recent blog, Hikvision covered a SecurityInfoWatch.com (SIW) article that provided an overview of ransomware, a cybersecurity attack that uses malware to exploit system vulnerabilities.

An excerpt from the article: “Ransomware is a type of malware (malicious software) that locks up a victim’s data so it can only be decrypted with an encryption key, which is provided to the victim once they make a ransom payment, often paid in cryptocurrency such as bitcoin, according to the [SIW] article. Verizon’s 2018 Data Breach Investigations Report uncovered that ransomware accounts for 85 percent of all malware found in healthcare systems and accounts for more than 50 percent of discovered malware.”

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.
