High-speed wi fi management networks are very important to Australian organizations. In particular, the area covered by the National Broadband Network (NBN) will increase. However, many hackers are adept at breaking into business networks. Therefore, if you want to keep your business safe, you must follow these guidelines.
Set a strong Wi-Fi password
The first necessary precaution is to reset the login credentials of your Wi-Fi router. All router models come with default usernames and passwords, such as "admin" and "password," which are easy to find online. Setting a password that is a combination of letters, numbers, and symbols of 12 characters or more can help reduce your exposure to network-based attacks.
More importantly, change the password every time an employee leaves the company. This not only prevents attacks by former malicious personnel, but also keeps hackers guessing.
Change the service set identifier (SSID)
The SSID is the name of the wi fi management that is transmitted to nearby devices, allowing you to identify which network you are connecting to. Manufacturers often set default SSIDs for routers like "Linksys" and "Netgear", but it is important to change as soon as possible. These names provide the router model and its default login, which increases the attack potential.
Renaming Wi-Fi doesn't eliminate advanced attacks, but it does serve as a bit of a deterrent for hackers looking for simple targets. A router with a custom SSID means that your company network is more secure than a typical router in the area.
Install firmware and software updates
Keeping track of updates is the key to network security. Be sure to check the manufacturer's website regularly for firmware patches. This is because firmware patches often release fixes as we discover significant product vulnerabilities. This tip also applies to security software. Firewalls, intrusion prevention systems, and antimalware always require the latest patches to protect against the latest threats.
Use a firewall
Your network router has a firewall that monitors incoming and outgoing traffic for malicious programs. Some routers may not have these built-in measures enabled during setup, so turn them on now.
Enable Wi-Fi Protected Access (WPA2)
WPA2 is a security protocol available on all certified Wi-Fi hardware. Encrypt the data to prevent your device from reading confidential information that you are accessing or sending over the Internet. Authorized users are assigned their own Wi-Fi login and encryption key. If a device is lost or an employee leaves the company, system administrators can simply revoke the login and avoid a serious data breach.
To enable this feature, go to the encryption settings of your router. Please note that some models use the Wired Equivalent Privacy Protocol (WEP), which is much easier to hack. In such cases, you should consider upgrading to a new WPA compliant router.
Disable Wi-Fi Protected Settings (WPS)
A WPS-enabled router makes it easy to connect your device to your network. Asking someone to grant Internet access to your device by simply pressing someone's PIN or button provides an easy way for an attacker to enter your network. Consider disabling WPS to keep your business safe.
Dynamic Host Configuration Protocol (DHCP) Control
The DHCP server automatically assigns each device a unique IP address so that it can connect to the network. The drawback is that this function does not evaluate the device that assigns the IP address. This means that the wireless device can reach the range of the router, obtain its IP address and access insecure local files. To fix this, consider manually assigning an IP address so that you can control the devices that connect to your network.
Separate access to public and private networks.
Implementing a commercial network accessible to both employees and the public is a recipe for disaster. Anyone can establish itself on your system and carry out a wide range of attacks. By creating a separate network for your visitors, you can prevent unauthorized people from hitting your most sensitive assets.
Keep your router in a safe place
Wi-Fi security also refers to the physical security of network components. Routers and access points (APs) have reset buttons
Delete Rebel AP
Another security issue related to physical security involves someone adding a fake AP to their network. These "corrupt" APs are generally installed by well-meaning employees who want to improve their internet connectivity in the office section. The problem is that the company is vulnerable to attack because certain APs lack certain security features. The best way to deal with this is to replace the fake AP with one that has been verified by security experts.
