In this digital world, future cybersecurity is the most important need of time. When big companies are in controversies for threatening users’ data privacy, new vulnerabilities are evolved from the system almost every day. To stay updated is the only way to outsmart the smart, ever-shifting attack vectors.  To avoid such instances, it is crucial to know and stay updated with the practices done by people all over the world. Implementing internet security and staying up to date with the security measures, the internet is now everywhere, and the roots of it have reached home, but the measures can be used in workplaces, schools, and of course, homes.  The article will cover how to update internet security, particularly those related to its internet-connected router configuration.

1.  Checking Router connectivity and authentication test

Routers allow administration and configuration using some ports in the local network. This is possible via Ethernet cable or wireless connectivity.  It is possible to configure your router via the web through sites like, but routers also allow connections for other services and ports, such as FTP(port21), SSH (22), Telnet (23), HTTP (443), or SMB(139,445)

Other well-known used services are whose default ports are established as internet standards – internet assigned Numbers Authority (IANA). The blocked port configuration might be set in your router by default, and you can enable only the services you need, disable all others, and block unused ports. Even for remote connections, except the necessary places.  Long and complicated passwords are used by people concerned with their security. If you don’t, we’d advise you to use them and change the old passwords of accounts that possess the same password as others.

2.  Conducting a Vulnerability  test on the router

Another vulnerability point in routers settings isis – tests for routers that can look for vulnerabilities through their automated search. This tool includes information, troubleshooting on possible problems in the router settings; it’s a good option to use such tools.

Some router tests scan for port vulnerabilities, malicious DNS server reputation, default or easy to crack passwords, vulnerable firmware, or malicious attacks. Some also include vulnerability analysis of the router’s web server component, scanning issues like cross-site scripting (XXS), code injection, or remote code execution.

3.      Checking connected devices in the network  router  

Due to bad practices and the use of vulnerable protocols, it’s possible for trusted devices to connect without proper authorization, also for untrusted devices to connect. It is important to be aware of the devices sharing router to avoid direct contact with malware, affecting network performance and speed. Private information is also threatened.

It’s performed by an automated tool or manual selection and verification of the router settings, by allowing trusted devices, by banning specific IP addresses or MAC addresses, respectively.

To perform the following inspection, the connected device list can be monitored, categorized by device type. Then, you must make the changes yourself using the router interface.

4.      Enable security options

This is one of the most logical practices for avoiding breaches, enabling security options that are available in the configuration of the router, checking router settings for security options, and enabling them is also a good option to avoid malware as it offers many options to secure the router, and keep the firewall intact, the options include configuration options that allow increased protection against known denial of service(DoS) attack, for instance, SYN Flooding, ICMP Echo, ICMP redirection, Local Area Network Denial(LAND), Smurf and WinNuke. If the quality is affected because of their access, then disable them.

5.   Keeping devices updated on the home router and rebooting them

The new form of vulnerability in routers is KRACK (key Reinstallation attack),  which allows the interception of traffic between devices connected to an access point in a Wi-Fi network and emphasizes the importance of updates again.

For if it were to happen to an unfortunate victim’s Wi-Fi network, the device should have to be connected to the Wi-Fi network, which will give access to all your connected devices. This network vulnerability is because of your outdated devices, such as laptops, smartphones, or tablets.  Installing updates to the firmware of the routers as soon as the updates are available. Changing computer preference configurations to “public network” mode lessens the risk of attack across trusted devices.

Rebooting the router right after updating devices helps reinstate all security measures for the router. This way, the connection is also rebooted and gives us better connectivity.

Cybersecurity is the need of the hour and needs more such precautions to be safe and up-to-date with all sorts of malware and vulnerabilities. It is important to be cautious towards router settings, and being a bit paranoid always helps.
