The 7 Main Network Security Types That Every Business Should Be Using

Share This

Network security is one of the most important aspects of any business. Without it, your company’s data is at risk of being hacked or stolen by cybercriminals. But did you know that it isn’t quite as simple as all that, and that there are many different types of network security ? 

Having well-rounded cybersecurity is now more important than ever, because in the last year 61% of all SMBs suffered at least one cyber attack !

In this blog post, we will discuss the seven types of network security that every business should have implemented in order to provide the best possible defense against cyber threats and hackers.

What is Network Security?

Network security is a set of procedures and technology designed to protect the integrity, confidentiality, and availability of computer networks.

It is essential for businesses to have these measures in place in order to prevent their confidential data from being compromised, stolen, or abused by malicious actors. Network security also helps organizations maintain their operations despite cyber threats. 

The 7 Main Types of Network Security Every Business Should Have

Whether your focus is purely network-based or more web security focused, these network security tools and measures are the main 7 every business needs in order to properly protect their network and data from cyber criminals and other threats.

1. Firewalls

A firewall is a network device that monitors incoming and outgoing network traffic and blocks suspicious activity based on predefined rules. Firewalls are typically used as the first line of defense against cyber attacks because they can block malicious packets from entering your network before they reach other systems.

2. Access Control Lists (ACLs)

Access control lists are used to manage access to network resources. They allow administrators to set rules that determine who or what is allowed to access certain parts of the network, such as specific systems or services.

3. Virtual Private Networks (VPNs)

A VPN creates a secure connection between two points on different networks, allowing remote users to securely connect to an internal corporate network without having direct access to it. VPNs also hide user IP addresses and can be used for bypassing geographic restrictions on content.

4. Intrusion Prevention Systems (IPS)

IPS detect malicious patterns in traffic and block them before they reach your system. This type of security is often used in combination with firewalls for added protection against cyber attacks.

5. Data Loss Prevention (DLP)

DLP is a type of security that monitors and analyzes data flows for the purpose of preventing unauthorized access or leakage of sensitive information. It can also be used to detect malicious activities such as phishing attempts, data tampering, and insider threats. Network segmentation is also an effective means of DLP.

6. Endpoint Security

Endpoint security is a system designed to protect individual devices and computer systems from malware and other threats by scanning incoming traffic for suspicious activity. The goal of endpoint security is to prevent malicious files from entering your system while allowing legitimate traffic to pass through safely.

7. Data Encryption

Data encryption ensures that only authorized users have access to confidential data by encrypting it with a cryptographic key. This method makes sure that even if a hacker were to gain access to the data, they would not be able to read it.

By implementing these seven types of network security, businesses can protect their networks from cyber attacks and ensure the security of their sensitive data. However, it is important to note that these measures alone will not be enough to keep your network secure. Businesses need to regularly monitor and update their security systems in order to detect and respond quickly to threats.

What Are the Different Types of Encryption in Network Security?

There are several different types of encryption used in network securit y. 

The most commonly used encryption algorithms include symmetric key cryptography, asymmetric key cryptography, and public-key cryptography

  1. Symmetric key cryptography uses the same secret key for both encrypting and decrypting data. 
  2. Asymmetric key cryptography uses two keys – a public key and a private key. 
  3. Public-key cryptography relies on one public key that is available to everyone and a private key that is only known by the intended recipient of the message. 

All three of these algorithms can be used to protect sensitive data from unauthorized access or alteration. 

In addition to these three main types of encryption, there are also other methods such as digital signatures and hashing algorithms which can provide additional layers of security. 

Digital signatures are used to authenticate the identity of the sender, while hashing algorithms are used to ensure that data has not been altered in transit. 

By using these techniques, businesses can ensure that their data is secure and only accessible to those who have been granted access.  

What are the Different Types of Scanning in Network Security?

Network security scanning is a process of detecting any weaknesses or vulnerabilities in a network.

This can enable organizations to identify and address potential threats before they occur. The most common types of scans include: 

  • Port scans
  • Vulnerability scans
  • Malware scans
  • And penetration tests

Port scan is a technique used to detect open ports on the target system which could potentially be used by attackers for malicious activities.

Vulnerability scans are used to identify weaknesses in the system that may allow attackers to bypass security measures and gain unauthorized access. 

Malware scan looks for malicious code such as viruses, worms, Trojans, and other forms of malicious software that might have been installed on the system without the user’s knowledge. 

Lastly, penetration testing is conducted to simulate an attack on the system in order to identify any remaining vulnerabilities.
