SNMP settings To reduce the risk of network load attacks using SNMP, we recommend you take the following measures, involving the products from other manufacturers as well. IPsec settings If you need to use a communication method without encryption function although you are concerned about network eavesdropping, we recommend you protect communication with IPsec. Limitation of cipher suites (*5) We recommend you do not use RC4/DES/3DES with lower cipher strength. Limitations for using SSL2.0/3.0 and TLS1.0/1.1 (*5) (*6) We recommend you do not use the older standard SSL2.0/SS元.0/TLS1.0/TLS1.1.įor older models that do not allow such settings, we recommend you protect with IPsec. We also recommend you create a certificate with a key length of 2048 bits or more. If you want to use a self-signed certificate, you need to install it on a PC that uses a browser. We recommend you use a certificate issued by a trusted third-party certificate authority instead of a self-signed certificate as the digital certificate to be used to encrypt the communication. See the instruction manual for supported communications. Installation of device certificate To prevent information leakage via the network, we recommend you use encrypted communication for the models that support encrypted communication.Įncrypted communication includes SSL/TLS and IPsec. If you have any questions, please contact the Ricoh's call center. do not have encryption function by themselves, so if you are concerned about network eavesdropping, we recommend you close the unused ports or protect them with IPsec described later.įor the applications that may be affected by closing the port, see the relevant pages of the instruction manual for each product on the Ricoh Web page, and check them In particular, rsh, telnet, ftp, lpr, etc. You can prevent unauthorized access from the Internet.Ĭlosing unused communication port (*3) (*4) We recommend you close unused network ports.

SMB settings (*2) We recommend you use the v3.0 or higher SMB.įor older models that do not allow such settings, we recommend you protect with IPsec. ・By setting the password for documents stored in document server, any third party cannot use the machines by setting a password for accessing the documents stored in document server. ・By performing user authentication such as the user identification or authentication (IC card or password input), only authorized users can use multifunction printers. We recommend you protect the data stored on multifunction printers by using the user authentication or the password for documents stored in document server settings. Be sure to change the password from the default value. Unauthorized access from the Internet can be prevented by operating machines in a local area network environment such as an inhouse LAN.īy changing the administrator password/supervisor password of machine, you can prevent the attacks (setting changes) by a malicious third party from the Internet. Operate machines with private IP address. (3) Precautions on hyperlinks (Open only trusted links) We recommend you be careful when opening hyperlinks in emails and bulletin boards on your PC, and open only trusted links.
