Network has become an important part of our live. We can imagine our lives without WiFi or Mobile networks for even a day. Networks facilitate data transfer, but do you know that without proper network security, your sensitive data can get compromised? So it’s important strengthen the Network Security.
What Is Network Security?
Network Security is a process of securing networks and data from cyber attacks such as breaches, intrusion, malware, and virus attacks. It is an umbrella term that refers to hardware and software solutions along with rules and processes related to networks. It is concerned with controlling various types of network-related security such as firewalls, VPN encryption, etc.
Why is Network Security Important?
Network security is a type of cyber security that is responsible for protecting networks. Cyber attacks on networks can expose various sensitive data, from Financial data to personal data. Companies across the globe suffer huge losses due to these Network attacks. Therefore, it is important to safeguard the Network.
Types:
Firewalls:
A network security device that manages and monitors every incoming and outgoing traffic on a network. It is responsible for allowing or blocking specific traffic based on a set of security rules.
Workload security:
As the name suggests, it is responsible for monitoring and protecting workloads of both cloud as well as hybrid environments. The distributed workloads come with a huge surface for attacks. Thus, it must be protected without having an effect on the agility of the business.
Network segmentation:
Segmentation makes everything easier, and the same is true for network traffic. Classifying network traffic into different categories ensures streamlining and effective enforcement security. These classifications are based on various parameters, such as endpoint identity.
VPN:
A virtual private network encrypts data by establishing a point-to-point tunnel for connection between a computer and a remote server. It masks your sensitive information, such as your IP address, and establishes a digital connection between your computer and a remote server.
Network Access Control (NAC):
Controlling access to any network is important. By doing this, you can monitor potential risks and allow only authentic users. Access control allows you to either block noncompliant endpoint devices or allow limited access.
Anti-virus and anti-malware software:
Malware is a broad category of malicious software. It can infect your system and cause damage. Anti-malware software can detect, remove, and prevent malware infections.
Application security:
Any software you use can be vulnerable to attacks. Application security measures help protect your software and Network from these vulnerabilities.
Behavioural analytics:
Behavioral analytics tools can help you identify unusual activity on your network that may indicate a security threat.
Cloud security:
Cloud has become the new storehouse of data and it hold many sensitive information that must be safeguarded. Security within cloud environment is measures that protect your data and applications in the cloud.
Data loss prevention:
Data loss prevention (DLP) technologies stop sensitive information from being leaked outside of your organisation.
Email security:
Email is a common carrier of cyberattacks. Security solutions can help protect your organisation from phishing attacks and other email-based threats.
Industrial network security:
As industrial operations become more digitized, they are increasingly vulnerable to cyberattacks. Industrial security measures help protect your industrial control systems (ICS) from threats.
Mobile device security:
Mobile devices are a popular target for cybercriminals. Security measures help protect your organization’s mobile devices and data.
Security information and event management:
SIEM products help security teams collect and analyze information about security events and identify potential threats.
Web security:
Web security measures help protect your organization from web-based threats, such as malware and phishing attacks.
Wireless security:
Wireless networks are more vulnerable to attacks than wired networks. Security measures help protect your wireless Network from unauthorized access.
Network Security Tools
There are many network security tools available on the market. Some of the most popular Cybersecurity tools include:
Load balancers
The load balancer is a network security tool that applies various algorithms to identify the traffic flow on the Network. It helps in avoiding potential risks and offers many cybersecurity advantages. One of its major tasks is to divert the traffic during a service attack or DDoS attack.
Sandboxes
Sandboxes is one of the most popular malware-blocking tools that run on IPS tools. It creates an emulated environment that.
A sandbox operates alongside IPS tools to block aggressive malware assess traffic and discover ways to block attacks. These can be port scanning.
NTA/NDR
Network Traffic Analysis tools use AI to assess network traffic. They monitor and compare real-time traffic to secure baselines. This baseline comparison helps detect unusual activities and instantly report attacks.
The Bottom Line:
Network security is an important step to monitor and control cyber-attacks on the Network and safeguard sensitive data from being exposed. This blog lists various types of network security tools.
