Different Types of Network Security

As a business owner or manager, you know that protecting your network is vital to the success of your company. But with so many different types of network security available, how do you choose the right one? 

In this blog post, we’ll discuss the different types of network security so you can make an informed decision about which type is best for your company.

Why Is Network Security Important? 

If your company conducts any of its business in a digital environment, it is integral that you protect the security of your most sensitive information. 

Cybercrimes result in global losses of $600 billion each year, equivalent to 0.8% of the global GDP.

All of the different network security types involve a wide range of defenses meant to guard against these malicious activities, including firewalls, vulnerability scanning, and other endpoint protection protocols.

There are also different types of encryption in network security such as asymmetric encryption and symmetric encryption to ensure the integrity of confidential information traveling over the network. With all these cohesive network security types and protective measures, your business is equipped with the tools it needs to stay secure online. 

Read on to explore the different types of network security in further detail to decide which are right for your business. 

Network Security Types: Which Are Right For Your Business? 

  • Firewalls 

Firewalls are common elements of network security. Their primary role is to act as gatekeepers between networks and the wider internet. 

Data packets are filtered by firewalls by comparing them against predefined rules and policies, thus preventing network threats from gaining access to your system.

  • Email Security

The importance of email when it comes to implementing network security tools cannot be overstated. Emails can contain numerous threats, such as scams, malware, phishing, and suspicious links.

In order to appear more convincing, many of these threats use personal information, so it is important to ensure that employees undergo sufficient security awareness training to detect suspicious emails. It is possible to configure email security software to filter out incoming threats and to prevent certain data from being shared outgoing messages.

  • Security and Event Management (SIEM)

Security and event management, otherwise known as SIEM, combines host-based and network-based intrusion detection systems to provide you with a complete overview of all traffic flowing through your network in real-time, as well as historical log file data.

SIEMs resemble intrusion prevention systems (IPS), which actively block attempted intrusions by looking for suspicious activity, violations of policy, unauthorized access, and other suspicious activity. As part of its function of keeping network administrators informed, an IPS can also log and alert security events.

  • Distributed Denial-of-Service Protection (DDoS)

Distributed Denial of Service (DDoS) protection is one of the most important types of network security. It defends your resources from malicious traffic floods, ensuring that they can continue to perform their services without being taken offline. 

When something untoward is detected the DDoS protection system uses automated algorithms to analyze the traffic and initiate efficient countermeasures often before any downtime has even occurred. Thus, it provides ample support to any online operations by defending infrastructure against debilitating attacks.

  • Disaster Recovery

Disaster recovery safeguards your business from data loss related to disasters, breaches, and unexpected outages. A disaster recovery plan is essential for businesses that want to maximize their chances of remaining afloat in the event of an unexpected disruption.

The different types of disaster recovery methods include:

  • Cloud Based Disaster Recovery
  • Network Disaster Recovery
  • Virtualized Disaster Recovery
  • Data Center Disaster Recovery
  • Encryption 

55% of business executives plan to increase their budgets for cybersecurity in 2021. Encryption is one of the core components of network security and involves the transformation of data from a readable form into an unreadable form. 

To achieve this, encryption algorithms are used to scramble data before it’s transmitted so that only authorized parties can read it. Depending on their complexity, encryption protocols typically use different types of algorithms and types of encryption in network security, including symmetric key algorithms, RSA encryption, public-key certificates, or digital signatures to keep your data encrypted. 

In addition to protecting data while in transit across networks, the different types of encryption in network security are also commonly employed as part of mobile application services, webmail applications and other online services to ensure they remain secure and private.

  • Vulnerability Scanning 

IT security teams and managed security service providers are responsible for identifying vulnerabilities in managing your network security. In this process, vulnerability scanners and various types of scanning in network security are used to identify security holes on computers and networks.

The different types of scanning in network security include: 

  • Virus/malware scans
  • Penetration tests on open ports
  • Network port scanning
  • Vulnerability scans
  • Rogue access point scans
  • User permission-level scans
