Network Security Tools Examples and Usage

Gone are the days when networks were only used to connect employees together inside of corporate offices. Today, networks can be found in every aspect of our lives, from connecting to the Internet at home or work to connecting with other social media platforms and services that keep us connected to those around us. This means that we have to have network security tools in place in order to protect everything we use online. Here are a few examples of some popular network security tools and their uses in today’s world.

What Is Network Security?

Network security is the practice of protecting a computer network from unauthorized access or malicious activity. It includes measures taken to protect the confidentiality, integrity, and availability of data stored on networked computers. Common security measures include firewalls, intrusion detection systems, and encryption technologies.

There are many different types of network security tools available to help protect your data. Here are just a few examples

Benefits of Network Security

  1. Increases the safety of your confidential data- When you have a network security system in place, it becomes much more difficult for unauthorized individuals to access your confidential data. This is because these systems use various security measures to protect your data, such as encryption and firewalls.
  2. Helps you comply with industry regulations- If you are required to comply with certain industry regulations, such as HIPAA or PCI, then having a network security system can help you meet those requirements.
  3. Protects your reputation- A data breach can ruin your reputation, but if you have a network security system in place, it can help prevent such breaches from happening in the first place.

Access control

There are many tools available to help secure networks including firewalls, intrusion detection systems, and encryption. Firewalls act as a barrier between a trusted network and an untrusted network. Intrusion detection systems monitor traffic for suspicious activity. Encryption scrambles data so that it is unreadable by anyone who does not have the key to decrypt it.

 

Security information and event management

A security information and event management system (SIEM) is a type of software that consolidates all of your security data in one place so you can more easily identify trends, potential threats, and areas of improvement.

There are many different SIEM tools on the market, but they all have the same basic features. Some common features include the ability to collect data from multiple sources, normalize that data, and run correlation rules to identify potential threats.

One of the most popular SIEM tools is Splunk, which has a free version that can be used for small businesses. Other popular options include IBM QRadar and HP ArcSight.

Wireless security

When it comes to securing your home network, one of the most important things you can do is use a wireless security protocol. The two most common wireless security protocols are WEP and WPA2.

WEP is an older protocol that is not as secure as WPA2. If you have an older router, it might only support WEP. In that case, you should still use it because it’s better than nothing.

WPA2 is the most current and secure wireless security protocol. If your router supports it, you should definitely use it.

Another important thing you can do to secure your home network is to use a VPN.

Application security

In order to have a secure network, you need to have security measures in place at the application layer. This means having a firewall in place, as well as intrusion detection and prevention systems. You should also consider using encryption for all of your data. Additionally, you need to make sure that your employees are trained in security best practices.

Data loss prevention (DLP)

DLP tools can be used to scan for and identify confidential data, track its movement, and block or restrict its use. They can also be used to monitor employee activity and prevent data breaches. Here are some examples of DLP tools in action:

  1. A DLP tool can scan emails for sensitive information such as credit card numbers or social security numbers. If it finds any, it can block the email from being sent or alert the sender.
  2. A DLP tool can monitor employee activity on a company network. If it sees someone trying to access confidential data they shouldn’t have access to, it can block them or raise an alarm.

Encryption Tools

Encryption is a process of transforming readable data into an unreadable format. This is done using an encryption key, which is a secret code that scrambles the data. The key can be used to unscramble the data, making it readable again. Encryption is used to protect information from being read by anyone who does not have the key.

Burp Suite

The suite includes an intercepting proxy, a web application scanner, spider, and many other features. It is one of the most popular tools in the industry and is used by many large organizations.

The tool is constantly being updated with new features and bug fixes.

Firewalls

A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet. Firewalls can be hardware-based, software-based, or a combination of both. Common firewall features include packet filtering, stateful inspection, application-level gateway, intrusion detection and prevention systems.

Conclusion

In conclusion, these network security tools are just a few of the many available options for protecting your data. It’s important to choose the right tools for your needs, and to keep your system updated with the latest security patches. With the right precautions in place, you can help keep your data safe from attacks.
