The Importance of Secure Wi-Fi For Small Businesses
Presented By
Black Pearl Matrix
What Are the Benefits of Secure Wi-Fi?
- Ensures protection against loss, theft or leakage of information and data.
- Access control, blocking applications and malicious sites.
- Scalability: it is possible to expand the possibilities of the network according to the growth and demand of the business.
- Network control and access visibility.
- Mobility: employees and collaborators can work from any point of the company, taking devices connected to meeting rooms and exhibitions, for example.
When we talk about the growth in the number of cyber attacks, we are not talking about hundreds, or thousands, or millions, but BILLIONS.
If you deal with sensitive data over Wi-Fi networks (as most companies do), you must have realized that you can incur huge losses. And to avoid them, it is essential to invest in efficient and modern security methods. Want to know how?
So keep watching and understand once and for all why you should be concerned about wireless network security!
The Importance of a Secure Connection
It is true that there are several practices and mechanisms to ensure the safety of online browsing, such as HTTPS connections (that padlock that appears on the browser window when you access your bank account, for example).
The problem is that, with the advent of smartphones and tablets, it has become more difficult to verify whether applications use some type of encryption or data security tool. And so, it became easier for other people with access to your network to intercept your browsing traffic.
The same applies in the case of a home network of computers with rudimentary protection systems (a simple firewall, for example). With the IP number of the machines, an attacker can easily capture the traffic passing through the server, including access passwords and personal information.
Below are some of the most common wireless network security methods and what their main advantages are:

WPA encryption
Wi-Fi Protected Access (WPA) was developed in 2003 to address the security issues of the older WEP (Wired Equivalent Privacy) method and is compatible with all wireless network adapters (except older models).
Its operation basically consists of encrypting data, authenticating users and ensuring that the network security key is modified in each packet. This system is based on the Temporal Key Integrity Protocol (TKIP), while the WEP method uses the RC4 algorithm for encryption.
Its main advantages over WEP are:
Encryption system improvements in the user authentication process, a 48-bit initialization vector, and a built-in function (Michael) to detect errors.
WPA2 encryption
WPA2, or 802.11i, is considered the final evolution of the WPA method. This system uses an encryption algorithm called Advanced Encryption Standard (AES) which is used by the US government in conjunction with TKIP.
Since AES is heavier, older network adapters do not support WPA2 and cheaper equipment may experience slow performance.
The advantages of this method over WPA are mainly greater security in wireless networks, support for the CCMP encryption mechanism and support for ad hoc networks, among other things.
EAP Authentication
The Extensible Authentication Protocol (EAP) is a security protocol that supports various authentication methods such as EAP-MD5, EAP-TLS, and EAP-TTLS. In other words, authentication can take place via security certificates or via passwords.
It is a widely used option for securing Wi-Fi networks, but it also works in conjunction with security devices such as token cards and encryption calculators. The main benefit of EAP is that it allows for additional authentication methods within the Point-to-Point Protocol (PPP).
Corporate WiFi: What Are the Benefits of This Solution?
The digital transformation of companies is already a reality and more and more corporations around the world are looking to implement new technologies that have better infrastructure and greater security, such as corporate WiFi.
According to the survey carried out by F5 Networks, published by the Terra portal, 87% of organizations are in the process of digital transformation and 77% are automating network operations to increase the efficiency of the technology yard.
In this sense, the corporate network is already an essential tool to complement a planned and secure IT infrastructure, as well as to improve internal and departmental processes, seeking to increase the organization and productivity of the team.

What Are the Benefits of Corporate WiFi?
Having a network that allows data sharing without relying on cables brings greater flexibility and agility to the company.
Deploying Enterprise WiFi Also Has Other Advantages:
Good value for money and economy. Unlike standard WiFi, the corporate network has a low initial investment for the company, as it is not necessary to install cables and purchase multiple routers, as well as it is not necessary to carry out reforms or adaptations in the environment to work.
Network maintenance costs and an exclusive IT team to support internet problems are eliminated, as the system is much more practical and easy to use.
Safety
With a much more robust security structure, corporate WiFi allows integration with access control programs, enabling the performance of a series of actions that contribute to a much safer network.
Such as:
• User authentication.
• Password management.
• Encryption and VPN solutions.
• Management of security policies.
• Modern network assets such as controllers, Access Point Indoor and Access Point Outdoor.
• Appropriate network planning.
• Division between corporate network and open network for non-employees.
• Follow-up of requests generated by external agents.

Flexibility, Mobility of Connection and Productivity
The connection is faster and more responsive everywhere in the enterprise. There will be no points where the WiFi is stronger or weaker, as the coverage area is wider and the network supports many more users, providing a quality connection to everyone.
And as mentioned, there will no longer be dependence on cables or the need to use accessories such as pendrives or even file downloads, as it becomes easier to adapt to the cloud, facilitating information sharing.
As a result, computers become lighter and more agile, helping to increase the productivity of its employees.

How to Implement?
Choosing a corporate network for implementation can be a rather complex task, as it involves security policies, network configurations and equipment and system functionality.
It is also necessary to analyze the needs of the company, taking into account some factors.
Such as:
• Number of employees.
• What are the information and contents shared on the network and what are their levels of importance.
• Level of office technology structure.
• Size of coverage area.
• Data transfer rate.
After collecting all this data, it is necessary to evaluate the networks available on the market, in order to avoid common mistakes such as choosing low-quality suppliers and misdirecting the solution. For these reasons, it is advisable to hire a company that specializes in the matter.

Practices to strengthen data security
BYOD forced IT managers to redesign their monitoring and corporate control policies. Until some time ago, institutions designed their wireless networks for strict use of their own equipment (PCs), which were fully configured and controlled internally.
There was total autonomy over what each employee accessed, with content restrictions, limits on system access permissions, and so on. And nobody could complain.
However, with the growth of IT costs in companies, as well as the increase in the use of personal mobile devices in the work environment, mobility was seen as a way to reduce costs and increase productivity in companies. As you can imagine, IT had to adapt to this phenomenon to make the corporation more competitive.
The point is that enjoying all the benefits that these modern ways of working make possible requires the development of a truly secure Internet security policy, which involves providing a security plan for BYOD and home office.
Limits on permission to access systems:
• Who owns the equipment.
• Mandatory installation of antivirus and security tools provided by the company.
• The elimination of ambiguities from a legal-labor point of view.
• Encryption of corporate data traffic.
You can increase Internet security by virtualizing the entire system and scheduling access to be released only during business hours, for example. Automatic backups and login through additional layers of protection, such as 2-factor authentication, are also strategic actions to mitigate the chances of intrusion by unauthorized users.
There are also other control instruments that must be adopted, such as the installation of apps that allow blocking and erasing data remotely, which is extremely useful in risk situations that were not foreseen. For external access, the use of Virtual Private Network (VPN) through authentication via digital certificate is highly recommended.
In some specific locations, the number of cyber attacks has grown absurdly, as is the case in North America, where the number of cases has increased by more than 55%.
FAQ – Frequently Asked Questions about the Importance of Secure Wifi
1. How important is it to have device security?
2. Which type of Wi-Fi is more secure?
3. What is the risk of using open Wi-Fi?
4. What are the security measures of a network?
5. How does network security work?
Conclusion
As we have already mentioned, it is very difficult to keep the company 100% protected from risks on the Internet, but surely, by implementing these security measures, it is possible to significantly increase the protection in your company and avoid security problems.
Most of these tips only require the involvement and dedication of managers and those responsible, without the need for a large investment, so start with simple actions and gradually move towards more complete solutions that will make your company increasingly protected.
Investing in information security solutions is essential, do not wait for an incident to occur to implement protective measures, as the damage caused by attacks and data loss are immeasurable, they can stop activities for days, generate loss of confidential data and even even, in some cases, jeopardize the future of the business.
