Question
Your friend lives in a large apartment complex and fears someone in the building has been accessing their wireless network to avoid paying service charges. They explain to you a large cable company installed the equipment and setup the wireless network using a predefined numeric pin. Upon further discovery, you are able to identify the encryption protocol as WEP. What wireless security enhancements would recommend to your friend? If your friend told you that they needed it as secure as possible so that they could work from home, what other security design elements could they implement. (e.g. signal strength, guard bands, frequency, access control…)
Explanation / Answer
In all actuality there is extremely no such thing as hack-proof or hacker-proof, much the same as there is nothing out there that is totally waterproof. Along these lines, in this answer i'll talk about making your remote wireless network safe as could reasonably be expected.
First let's focus on WEP weaknesses:
To secure a wireles router the following things you could do as mentioned below:
Enable WPA2 Wireless Encryption; Create a Strong SSID Network Name and Preshared Key
On the off chance that you aren't utilizing Wi-Fi Protected Access (WPA2) encryption to ensure your remote system/network, at that point you should leave your front entryway completely open since programmers can practically walk directly into your system. In case you're utilizing obsolete Wired Equivalent Privacy (WEP) security, which is effortlessly broken in seconds by most programmers or hackers, you ought to think about moving up to WPA2. More seasoned routers may require a firmware move up to include WPA2 usefulness. Check your router producer's manual to figure out how to empower WPA2 remote encryption on your switch.
You will likewise need to make a solid SSID (remote system name). On the off chance that you are utilizing your router's default SSID name (i.e. Linksys, Netgear, DLINK, and so forth.), at that point you are making it less demanding for programmers to hack your system. Utilizing a default SSID or a typical one helps programmers in their mission to break your encryption since they can utilize prebuilt rainbow tables related with normal SSID names to split your remote encryption.
Make an extensive and irregular SSID name despite the fact that it may be difficult to recollect. You ought to likewise utilize a solid secret key for your preshared key to additionally dishearten hacking endeavors.
Turn On Your Wireless Router's Firewall
?On the off chance that you haven't effectively done as such, you ought to consider empowering your remote router's built-in firewall. Empowering the firewall can make your system less noticeable to programmers searching for focuses on the web. Numerous router based firewalls have a "stealth mode" that you can empower to help decrease your system's perceivability or say visibility. You will likewise need to test your firewall to guarantee that you have arranged it effectively.
Use an encrypted personal VPN service at the router level
?Virtual private network used to be an extravagance that exclusive extensive organizations could bear. Presently you can purchase your very own VPN benefit for a little month to month charge. An individual VPN is one of the greatest barricades you can toss at a hacker.
An individual VPN has the ability to anonymize your actual area with a proxied IP address and can likewise set up a mass of solid encryption to ensure your system movement. You can buy individual VPN benefit from sellers, for example, StrongVPN, and others for as meager as $10 a month or less as of January 2018.
On the off chance that your router supports individual VPN benefit at the router level, at that point this would be the most ideal approach to actualize an individual VPN as it enables you to encode all activity entering and leaving your network without the problem of setting up VPN client software on your PCs.
Disable the Admin via Wireless Feature on Your Router
?Another approach to assist keep hackers from upsetting your remote network is to cripple the administrator by means of remote setting. When you cripple the administrator by means of remote element on your router it makes it with the goal that lone somebody who is physically associated with your switch by means of an Ethernet link can get to the administrator highlights of your router. This keeps somebody from driving by your home and getting to the authoritative elements of your router on the off chance that they've traded off your Wi-Fi encryption.
Tip: You can always check how many devices are connected to your network by logging as admin. If there's any suspicious or unknown MAC (device) is connected you can kick them off your network. Another thing you can do is to set bandwidth allocation by providing priorities to your most favorable device.
These are the must done steps in order to prevent your personal network.

Now look at the design elements that are add-ons or for a large network as mentioned below:
Wireless network were initially made arrangements for scope just, however with all the cell phones, tablets, workstations and so forth out there- - the present wireless network must be anticipated limit.
With the expanded request on both your remote and wired foundation, you should consolidate high limit load balancing.
This implies, when one access point is over-burden, the framework will effectively move clients starting with one AP then onto the next relying upon the limit that is accessible.
?Role based access control (RBAC) enables you to assign roles based on who, what, where, when and how a client or gadget is endeavoring to get to your network.
Once the part of the device or end-client is characterized, access control polocies or principles can be implemented.
?With client desires expanding, it's important that you're ceaselessly estimating performance from the end-clients point of view. This implies being able to see your end-clients continuously, what sort of gadgets you are utilizing, what kinds of applications you are utilizing, and the status of the different netwoking components.
?You should have application filtering in place in order to protect user from content that might contain malicious threats as well as to prevent possible performance issues.
