15 Different Types of Network Security Defence Measures You Should Know About

 

We all lock our doors to keep burglars out, but what about the digital burglars lurking in the shadows of cyberspace? A breach in your network can lead to unauthorized access and the theft of sensitive data that can cause irreversible damage to your business.

The aftermath of a cyber attack isn’t just limited to data loss; it can also tarnish reputations and lead to financial ruin. According to a report by Cybersecurity Ventures, cybercrime damages are expected to cost businesses $10.5 trillion annually by 2025, up from $3 trillion in 2015, a staggering figure that highlights the urgency of robust network security measures.

Inadequate network security makes your business an easy target for cyber-criminals and, in the most extreme cases, can represent an existential threat to your business” says George Terrone, Co-Founder of ITSco

The significance of understanding the nuances of network security can never be overstated, as it is essential for safeguarding your personal information and data security.

Comprehensive knowledge of various network security types is essential for safeguarding sensitive data about your business, your employees and your customers.

 

What is Network Security?

Network security represents your shield against a wide array of cyber threats. At its most fundamental level, it refers to the strategies and techniques designed to monitor and prevent unauthorized access, modification, or exploitation of a computer network and its accessible resources.

Types of Network Security

Understanding some of the most common and effective types of network security will allow you to take a multi-layered, holistic approach to safeguarding your resources against a multitude of threats.

 

1. Firewalls

Firewalls act as a barrier between your secure internal network and untrusted external networks like the internet. A set of rules govern what kind of traffic is allowed or disallowed, making it a first line of defense.

2. Antivirus/Anti-malware

This software scans for and removes malicious software from your computer system. They also offer real-time protection against malware installation, including ransomware and trojans.

 

3. Data Loss Prevention (DLP)

A study by Varonis reveals that 41% of companies have more than 1,000 sensitive files open to every employee, emphasizing the need for data loss prevention measures.

DLP technologies prevent sensitive data from leaving your internal network. They do this by identifying and monitoring sensitive data while it’s in use, in motion, or at rest.

 

4. Network Segmentation

This technique divides the network into various segments, each requiring unique permissions. By doing so, the risk of an intruder gaining complete control over the network is significantly reduced.

 

5. Virtual Private Network (VPN)

VPNs allow for secure remote access to the network by creating an encrypted tunnel for data to pass through. This ensures data integrity even over unsecured networks.

 

6. Identity and Access Management (IAM)

IAM technologies control who can gain access to certain aspects of the network. They use various tools like multi-factor authentication, identity-based security policies, and more.

7. Types of Encryption in Network Security

Secure Socket Layer (SSL) and Transport Layer Security (TLS) are among the types of encryption techniques that help decrypt the data. These ensure that data remains private during transmission.

 

8. Types of Scanning in Network Security

This includes tools like port scanning and vulnerability scanning. These scans identify open ports and existing vulnerabilities in the network to remediate potential threats.

 

9. Security Information and Event Management (SIEM)

SIEM offers real-time analysis of security alerts generated by various network hardware and software. It gathers and analyzes data to offer actionable security insights.

10. Intrusion Prevention System (IPS)

An IPS detects and prevents known and unknown threats in real-time. It is often integrated with other security appliances for a holistic approach to security.

 

11. Endpoint Security

This security measure protects the corporate network when accessed via remote devices like smartphones or laptops. Endpoint security software ensures that all endpoints meet security standards before they gain access.

 

12. Web Security

Web security solutions restrict access to harmful websites and downloads. They block malware-laden sites and phishing attacks, maintaining a secure browsing environment.

13. Email Security

Email security prevents unauthorized access and data loss during email communication. It can include procedures to safeguard the confidentiality of personal information shared via email.

 

14. Application Security

Application security involves securing all software and applications against different types of vulnerabilities. These might otherwise give attackers the ability to gain access to the system.

 

15. Cloud Security

This ensures the safety of data stored in cloud infrastructures. It involves a set of policies and controls to protect against both external and internal cyber threats.
