Three Key Components of Network Security

Part of the revolution we experience in the world presently, is as a result of digitization. Our way of living and doing things has also changed. In protecting your organization’s reputation, it is imperative to protect its network against any unauthorized access. No any enterprises should overlook their network security. Effective network security targets various threats and stops them from entering or spreading on your network. Therefore, it is paramount to observe the following key components.

What Is Network security?

Network security aims for protecting the usability and integrity of your network and data under a secure environment. It is a kind of the tool, tactic and security policy to protect the networking infrastructure from any action of unauthorized access, misuse, malfunction, unauthorized modification, destruction, or improper disclosure.

Which Three Key Components of Network Security You Need To Know?

1. Network Access Control 

1a. How Network Access Control (NAC) Benefit The Network Security?

Access control means minimizing the risk of unauthorized access to network systems. It is a fundamental component of security compliance programs that ensures security technology and access control policies are in place to protect confidential information of a company.

Limited the threat actors to access your network, the amount of damage must be reduced. However, you have to remind that authorized users can also be the potential threats sometimes. Access control allows you to increase your network protection by limiting user access and resources.

1b. How To Set Up A Network Access Control (NAC) Framework?

1. 1. Install the NAC server and configure all wireless access points as well as switches to use the NAC server.
   2. Define basic profiling and authentication rules on the NAC server.
   3. Define inspection and compliance policies. These dictate the security posture checks.
   4. Test and fine-tune your rules and policies.
   5. Define alerts and reports, such that failed authentications are logged and sent to your security team for analysis. Also, you have to generate weekly reports for checking data.
   6. Go live. After you are confident that your rules, policies, and alerts are all functioning as intended, roll out the NAC solution for a subset of your users.

2. Email Encryption

2a. Why You Need Email Encryption For Your Business?

Without encryption any stranger can access to the information which is contained in your mail. In case your mail is not encrypted, some wrong elements can make use of your business information for their ulterior motives. That means your competitors can use such information against your business.

2b. What Are The Best Email Practices?

1. 1. The Best Email Security, Use strong passwords that are unique
   2. Using two-tier authentication
   3. Watch out for phishing emails
   4. Never open unexpected attachments without scanning
   5. Do not let employees use company email addresses for private messages
   6. Scan all emails for viruses and malware
   7. Use a robust spam filter
   8. Never click the “unsubscribe” link in spam emails

3. Firewall Setup

3a. Why You Need A Firewall For Network?

A firewall is able to filter the incoming and outgoing network traffic, in order to protect the security of your network. And the purpose of a firewall is to reduce or eliminate the occurrence of unwanted network communications while allowing all legitimate communication to flow freely.

Without a firewall for the network, any connection can flow freely in or out of your network, including connections from some malicious sources. This means you could experience unauthorized access to networked files. It may result in a data breach or malware infection to your business.

3b. How Does A Firewall Work?

A firewall scans the contents of the data packet and then determines whether to let it through based on the rules you set before. It works by checking data packets against an internal list of rules, such as:

1. 1. IP addresses: filter out traffic from suspicious IPs
   2. Domain names: block traffic from known malicious domains
   3. Ports : deny traffic trying to enter through a certain port
   4. Contents: block data packets containing certain keywords

4. Conclusion

After a comprehensive penetration test, your organization can view its system as both the hacker and a network security specialist, to identify what you need to improve. Get in touch with us now for more information!
