1.7. Static IP Addres s

When delivered from the Factory the camera will be supplied with a static IP address on the Ethernet connection of:
HTTPS://192.168.10.20 Connect to this address using a standard Web Browser (Firefox recommended) from a PC
configured on the same subnet address.

1.8. Secure Disposal Instructions

Sicore II stores images and information that in many countries would be classed as personal data under the relevant data protection legislation, therefore it is important to decommission and/or dispose of this device carefully, removing all data and settings on the device prior to its disposal. The removal of such data is your responsibility as part of the disposal process and therefore, as a minimum, the following steps should be followed:
• Delete all data in the results database (See Operating Instructions Handbook (ref. Table 2) on how to achieve this). This will ensure no images or data such as plate reads, classification, speeds etc. remain stored on the camera on the internal SSD.
Introduction
14
• Wipe the system configuration (see section 4.6.6 on how to achieve this). This will ensure that all configu ration such as security certificates, passwords and settings are returned to the factory defaults.
Whether or not the above steps are followed, if any personal data remains on any Sicore II units following their disposal, Siemens shall not be liable to compensate you or any third parties for any loss or damage resulting from the continued existence, use or dissemination of such data, and you shall indemnify Siemens against any such claims it may receive directly from third parties.

1.9. Recycling and Disposal

In compliance with the European directive 2002/96/EC on waste electrical and electronic equipment (WEEE), the appliance must not be disposed of with household waste, but taken to an authorised waste separation and recycling centre. Batteries need to be handled appropriately and disposed of correctly
Battery Directive 2006/66/ EC
The Sicore II Camera is fitted with a small rechargeable lithium coin cell for backup purposes. The battery is to be recycled in an appropriate manner.
Security Recommendations
15

2. Security Recommendations

2.1. Password Security

Siemens strongly advises changing the username and password on installation (see Section
8.1). Ideally the password should be unique for each site and should have a management process defined that contains:
• A process for creating secure passwords
• A method for authorised users to gain access to password
• A requirement that passwords are changed at regular intervals.
The preferred alternative to passwords is to use Soft PKI Certificates.

2.2. VPN

Where the VPN is provided by on-site communications equipment (ADSL, 4G) instead of Sicore II, care should be taken to secure access to and from the communications equipment by unauthorised personnel. This includes, but is not limited to, firewalls at the upstream communications equipment and physical security.
An industry-standard security risk assessment shoul d also be performed to assess any risks introduced by the communica tions equipment.

2.3. FTP

The use of FTP (File Transfer Protocol) is not advised without additional security precautions as it does not provide any protection from the following attacks:
• Man-in-the-middle – a compromised device can intercept the FTP file transfers and capture confidential/personal information, for example images and Vehicle Registration Marks. This information can be considered personal in some countries and therefore covered by the GDPR/O ther regulations.
• Password snooping – the password for access to the FTP server is sent unencrypted, this means that an attacker monitoring the network can capture usernames and passwords that would allow them to bypass security on the server. This would also allow an attacker to inject fake data.
• Passwords may become uncontrolled – ca re should be taken du ring installation t o make sure that the passwords are transferred in a secure manner. Failure to do so may lead to leaking the passwords - allowing attackers access to the FTP server.

2.4. NTP

The Network Time Protocol does not provide any authentication. This means that an attacker can fake the NTP messages and cause an NTP client to use the incorrect time. It is advised that if NTP is to be used, multiple NTP servers should be set up and, where possible, Trusted Time should also be used.
