Template:Security guidelines

Security measurement type	Security measurement name	By default	Details
DDOS Prevention	SYN Flood Protection	On	A SYN flood is a form of denial-of-service attack in which an attacker sends a succession of SYN requests to a target's system in an attempt to consume enough server resources to make the system unresponsive to legitimate traffic.
	Remote ICMP Requests	On	An Internet Control Message Protocol (ICMP) flood attack, also known as a Ping flood attack, is a common denial-of-service attack in which an attacker attempts to overwhelm a targeted device with ICMP echo-requests (pings).
	SSH Attack Prevention	Off	A Secure Shell (SSH) flood attack, is a common denial-of-service attack in which an attacker attempts to overwhelm a targeted device with SSH requests.
	HTTP Attack Prevention	Off	A Hypertext Transfer Protocol (HTTP) flood attack is a common denial-of-service attack in which an attacker attempts to overwhelm a targeted device with HTTP requests.
	HTTPS Attack Prevention	Off	HyperText Transfer Protocol Secure (HTTPS) flood attack is same as HTTP flood attack but using HTTPS protocol instead of simple HTTP
Port Scan Prevention	Port Scan	Off	A port scan is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port.
	SYN-FIN attack	Off	An attacker may send TCP/IP packets with the SYN and FIN TCP/IP flags set to a target system, ranging across all ports, to find open TCP/IP ports for further attacks. The target system will drop packets which are destined to open ports and send back RST/ACK packets for closed ports. The attacker may gather information from the system responses.
	SYN-RST attack	Off	SYN-RST attack, also known as TCP reset attack, is an abrupt closure of the session which causes the resources allocated to the connection to be immediately released and all other information about the connection is erased. TCP reset is identified by the RESET flag in the TCP header.
	X-Mas attack	Off	Christmas Tree (X-Mas) Attack is designed to send a very specifically crafted TCP packet to a device on the network. This crafting of the packet is one that turns on a bunch of flags. There is some space set up in the TCP header, called flags. And these flags all are turned on or turned off, depending on what the packet is doing.
	FIN scan	Off	FIN packets can bypass firewalls without modification. Closed ports reply to a FIN packet with the appropriate RST packet, whereas open ports ignore the packet on hand. This is typical behavior due to the nature of TCP.
	NULLflags attack	Off	A Null Scan is a series of TCP packets that contain a sequence number of 0 and no set flags. In a production environment, there will never be a TCP packet that doesn’t contain a flag. Because the Null Scan does not contain any set flags, it can sometimes penetrate firewalls and routers that filter incoming packets with particular flags.
Access Control	Remote SSH access	Off	All Remote access is disabled by default. If user is using remote access feature it may be a security threat. If user decides to use this feature - it is recommended to use a strong password.
	Remote HTTP access	Off	All Remote access is disabled by default. If user is using remote access feature it may be a security threat. If user decides to use this feature - it is recommended to use a strong password.
	Remote HTTPS access	Off	All Remote access is disabled by default. If user is using remote access feature it may be a security threat. If user decides to use this feature - it is recommended to use a strong password.
	Remote CLI access	Off	All Remote access is disabled by default. If user is using remote access feature it may be a security threat. If user decides to use this feature - it is recommended to use a strong password.
	Local SSH access	On	Enabled by default for user convenience, allows possibility of configuring the device when user is in the same LAN.
	Local HTTP access	On	Enabled by default for user convenience, allows possibility of configuring the device when user is in the same LAN.
	Local HTTPS access	Off	By default turned off - where is no scenario where HTTPS usage would be needed "out side the box".
	Local CLI access	On	Enabled by default for user convenience, allows possibility of configuring the device when user is in the same LAN.
Block Unwanted Access	SSH Access Secure	On	By default, device allows a maximum of 5 login attempts (user defined). If all attempts are used, device will block SSH acccess from that source.
	WebUI Access Secure	On	By default, device allows a maximum of 5 login attempts (user defined). If all attempts are used, device will block WebUI acccess from that source.
Configuration via SMS	SMS Utilities	By router admin password	Default authorization method for configuration via SMS command is by router admin password. It's very important to have a strong password for admin account.
Default admin password	First login	On	Default password for Teltonika's devices is admin01 (weak password) but on first login to WebUI - RutOS forcefully requires user to change it. It is recommended to use a strong password
Certificates	Root CA	Pre-uplouded	Root CA certificate are only needed if you want to use HTTPS for your services. There is a default file already preloaded in this device which will be overwriten by any uploaded file.
Universal Plug and Play	UPnP	Not installed / Off	UPnP doesn't require any sort of authentication from the user. Any application running on your computer in LAN can ask the router to forward a port over UPnP, which is why the malware can abuse UPnP. Recommendation - If you don’t use it when leave it not installed or turned off.
Universal Asynchronous Receiver – Transmiter	UART	By router admin password	Many manufacturers are implementing UART interfaces on their devices. If this interface is not password protected, security of the device may be compromised. If malicious 3rd party gains physical access to the device it will have full control of the router via UART interface, this is a reason why our devices have password protected UART interfaces.
