Network security settings of the Belkin Router

The network security setting router of the Belkin router is mainly used to provide Internet access support for computers on the Intranet. It also plays a role in ensuring network security, after the configuration, the vro can block viruses and network attacks from outside the network. Today, I will take the Belkin router as an example to introduce how to configure the router and How to Ensure network security. 1. A physical security router routes data packets Intelligently Based on the IP address. If a device connected to the router places its network adapter in a chaotic mode, it can receive all broadcasts, this includes passwords, POP3 communications, and Web communications. Therefore, ensure that physical access to your network device is safe to prevent unauthorized computers and other devices from sniffing the local LAN.
2. disabling the direct IP address broadcast www.2cto.com Smurf attack is a denial of service attack. In this attack, attackers use fake source addresses to send an ICMPecho request to your network broadcast address, this requires all hosts to respond to this broadcast request, which at least reduces your network performance. 3. Modifying the default password 80% the network security breakthrough event is caused by a weak password. Most routers generally use the default password, which can easily be maliciously infiltrated, so you need a complex and reliable password.
4. The main purpose of disabling the ICMPpingPing command is to identify the host currently in use and cancel the remote user's ability to receive ping requests, it is easier to avoid scanning activities that are not noticed or prevent hackers looking for targets that are easy to attack. In this way, at least your server is unlikely to become an attack target. 5. Address filtering rules are set up on the vro to filter inbound and outbound network violations based on IP addresses, except for special unusual applications, all IP addresses that attempt to access the Internet from your network should have an IP address allocated to your LAN, all the communications with the source address or the reserved and unroutable target addresses should be allowed through this vro. 6. Disable IP source routing IP protocol to allow a host to specify the route of data packets through your network, rather than allowing network components to determine the optimal path. This function is used to diagnose connection faults. However, this function is rarely used. The most common use of this function is to mirror your network for reconnaissance purposes, or to search for a backdoor in your private network, this feature should be disabled unless you specify this feature for fault diagnosis only.

If you do not need it, disabling the authentication protocol used by HTTPHTTP is equivalent to sending an unencrypted password to the entire network, however, there is no valid rule in the HTTP protocol for password verification or one-time password. Although this Unencrypted Password is very convenient for you to set a vro from a remote location, it is very insecure. 8. data packet filtering is suitable for your network according to your requirements for network security level. For high network security, especially when storing or keeping confidential data, in this rule, all ports and IP addresses must be blocked except for the network function.
Most networks will implement a Filtering Scheme Based on rejected requests. When this filtering rule is used, you can block ports that are not used in your network and the ports that are commonly used in investigation activities to enhance the security of your network.
The above are some common knowledge about network security of the Belkin router. For your network security, please refer to this article for security settings.
