Why is Network Security Important?

June 30, 2023

Once perceived as a secondary IT concern, network security has swiftly ascended the ranks to become an imperative aspect of any successful business IT strategy. From protecting sensitive data to defending against cyber threats, the significance of all the different network security types for businesses cannot be overstated.

In this blog post, we will delve into the multifaceted importance of network security and shed light on the tangible benefits it brings to organizations, with detailed information regarding:

  • Different types of network security
  • Types of encryption in network security
  • Types of scanning in network security

 

Understanding the Importance of Network Security

The relentless rise of sophisticated cyber threats has brought on severe consequences for organizations of all sizes – so much so that the cost of cybercrime has reached $10.5 trillion USD annually.

The financial losses, reputational damage, and legal liabilities resulting from successful cyber attacks can cripple businesses, undermining trust among customers, partners, and stakeholders. According to studies, over 60% of SMBs fail after just one cyber attack.

Consequently, organizations like yours must recognize that robust network security measures are indispensable in safeguarding your valuable assets, maintaining uninterrupted operations, and preserving your hard-earned reputation in the face of an evolving and persistent threat landscape.

This includes robust email security, application security, and data loss prevention (DLP) technologies. Let’s look at some of the standard network security types and which are best suited for securing sensitive information and networks.

 

All the Different Types of Network Security

Did you know that 42% of cybercrimes are aimed at SMBs? Let’s see how these different network security types can keep you from being one of them.

 

Firewalls

Firewalls act as the first line of defense by monitoring and controlling incoming and outgoing access to the network. They examine data packets, filtering out potential threats and unauthorized access attempts.

Firewalls can be hardware-based (physical devices) or software-based (applications or services), and they enforce security policies based on predefined rules and configurations.

 

Intrusion Detection and Prevention Systems (IDPS)

IDPS are designed to detect and respond to malicious activities within a network. They analyze network traffic, looking for patterns and signatures associated with known attacks. When an intrusion is detected, the IDPS can alert administrators, block suspicious activity, or even automatically take remedial action to prevent further damage.

Virtual Private Networks (VPNs)

Virtual Private Network (VPNs) establish secure connections over public networks, such as the internet. By encrypting data transmitted between remote users and the corporate network, VPNs ensure confidentiality and integrity.

This networking security tool is especially crucial for organizations with remote workers or multiple locations, as it allows for secure access to internal resources and data.

 

Access Control Systems

Network access control is the process of granting or denying permissions to network resources based on user credentials and predefined policies.

Authentication mechanisms, such as passwords, biometrics, or multifactor authentication (MFA), verify the user’s identity. Authorization then determines the level of access granted, limiting users to only the resources necessary for their roles.

 

Network Segmentation

Network segmentation is a fundamental strategy in network security that involves dividing a network into smaller, isolated segments. By creating distinct segments, you can enhance your overall security posture and mitigate the impact of potential security incidents.

Each segment can have its own set of security controls, access policies, and monitoring mechanisms, reducing the risk of lateral movement by malicious actors within the network.

 

Vulnerability Scanning

Various types of network security scans provide you with valuable insights into the weaknesses within your network infrastructure, helping you prioritize and implement effective security measures to mitigate risks and protect your valuable assets.

The different types of scanning in network security include:

  • Port scanning
  • Vulnerability assessment scans
  • Discovery scans
  • Web application scans
  • And more

 

Encryption

Encryption converts sensitive data into a scrambled format that can only be deciphered with the appropriate encryption keys. It ensures the confidentiality and integrity of data, both at rest (stored) and in transit (being transmitted).

Among the common types of encryption in network security include:

  • Symmetric Encryption: Uses a single key for both encryption and decryption. It is fast and efficient but requires secure key distribution.
  • Asymmetric Encryption: Utilizes a key pair consisting of a public key for encryption and a private key for decryption. It provides secure key exchange but is slower than symmetric encryption.
