Question

Explain how you would secure your company’s internal wireless network to prevent unauthorized access, including how it’s configured and what policies might need to be created and enforced to ensure employee compliance.

Answer 1

Let us understand how a wireless network works initially.

1)The wireless network sends its signals through the air upto some range in a company's internal wireless network.

2)The device which is in that particular range can pull that signal and access the internet.

3) If we don't take necessary precautions, any device within that range can access our network.

Now, let us understand how to prevent unauhorized access and how it's configured

• we should use encryption on a wireless network i.e., we should encryption which is being sent over the network. Encryption makes the information you sent into code which can not be accessible by others.Your computer, router, and other equipment have to use the same encryption.Eg:-WPA2 encryption.
• We should limit the access to the network.All the deIvices which are able to communicate with a network are assigned a unique MAC address so that routers can allow only devices with particular MAC addresses to access to the network.
• It is also important to secure a router as it is the communication between a local network and internet.The router can be kept secure by changing the preset password of router,updating your router time to time,logging out as admin to avoid piggyback of sessions and also disable remote access to desktop features
• Apart from all the above steps, we should follow the basic steps of protecting our computer like having an antivirus, firewall and antispyware etc.
• Also use strong passwords to access the network.

The policies might need to be created and enforced to ensure employee compliance are as follows:-

• It is important to have the security procedures written down in order to understand and you make them easily accessible for every employee.
• Make some mandatory courses for every employee to make them understand each and every security policy and conduct time to time assignments or quiz on the same.
• Make employees understand why security procedures are necessary.Give them some reasons and examples on the same.Tell them following those procedures are a part of company success.
• Whenever an employee wants to view the security policies and procedures, make sure that they are easily accessible through a link or a web application in your network and  use digital documents to make sure all policies and procedures are easily accessible for every employee.
• Provide Timely remainders to employees to view the latest updated security policies through mails or personal communication. If possible reward all the employees who strictly follows security procedures because of which others may get inspired.
