Today, the world is interconnected than ever before. This is courtesy of advancements in networking technology. A huge amount of confidential, commercial and personal data is stored on both private, and openly accessible networks. The vital significance of this data is what makes network security so important, especially among business organizations where IT networks must be managed securely.
Dependency on the internet by organizations and individuals is at an unimaginable level. This has spawned a range of network attacks and breaches that have often left organizations reeling under penalties and weakened brands. However, with adequate network security, you can transmit and store data on a safe network.
The following are 14 types of network security:
1. Behavioural Analytics
Behavioural analytics is used to detect pattern changes in the network, which appear to be out of the norm, with the help of software tools. The analytics tool catches the anomaly and alerts the concerned professionals, so further action can be taken. Behaviour-based malware detection systems search for indicators that can flag the unauthentic program’s elements.
Once these are detected, they are highlighted as malware. Although behavioural analytics are helpful, they aren’t by themselves enough to protect your network and systems from malware. To make these types of network security more effective, combine it with signature-based detection.
2. Application Security
Application security is used to find and secure loopholes in an application. Once it finds an application’s vulnerability, it fixes them. This protects an app from cyber-attacks. With the help of hardware, software, and processes, it keeps your assets intact.
3. Antivirus and Antimalware Software
Before you decide to use anti-malware and antivirus software, you should know the difference between a “malware” and a “virus.” A virus is a specific term, used to define a kind of malware that tends to replicate and spread across a network, while malware is a general term for the different types of malicious code.
Viruses, adware, worms, nagware, spyware, Trojans, and ransomware fall under the malware category. The reason you need to purchase the two types of software is mainly premised on the fact that no technology can cover everything.
An antivirus only detects viruses, unlike anti-malware. When the two software is working together, they can scan for viruses and malware on entry, remove them, and fix any damage they might have caused. The first antivirus software made use of signature-based malware detection to look for malicious sequences or network traffic. It offered adequate protection from a variety of threats, other than being easily available, fast, and easy to run.
4. DLP (Data Loss Prevention)
DLP is a type of network security used by organizations to secure their communication networks. These types of network security can protect sensitive data. Today, organizations routinely prohibit their employees from forwarding, uploading, or printing critical information without following the appropriate procedure.
5. Endpoint Security
Endpoint protection or endpoint security used to protect corporate networks when accessed from remote devices. Remote access opens up a potential security threat at the entry point.
6. Email Security
Email gateways are popularly used to spread spam, malware, and to launch phishing attacks. Social engineering methodologies have made these threats appear sophisticated and genuine. An email security application protects data and restricts access to an email account. It blocks incoming attacks and controls outbound messages.
A firewall is a type of network security for monitoring outgoing and incoming traffic based on predefined rules. It acts as a barrier that separates untrusted networks from trusted ones. Software, hardware, or both can be used as a firewall.
8. Mobile Device Security
This term is used to describe all the security measures designed to protect data transmitted via mobile devices (tablets, laptops, and smartphones), and the data stored on them. With IT organizations turning to mobile devices for their corporate applications, one needs to be in control of the devices accessing their network.
9. Network Segmentation
Network segmentation technology classifies a computer network into sub-networks. These network segments enforce easier security policies and boost performance.
SIEM stands for ‘security information and event management.’ This is a combination of Security Event Management (SEM) and Security Information Management (SIM). SIEM products make sure all relevant information has been gathered in one place for the security staff to identify potential threats and respond to them. You can use both virtual and physical appliances to server software as a SIEM product.
NAC is short for Network Access Control. It strengthens a network by controlling who can access it. There is no guarantee that every user in your network will be authorized. However, by blocking any noncompliant endpoint device, you can protect your network from potential security breaches.
VPN stands for ‘Virtual Private Network.’ It is defined as the act of encrypting connections over the internet from their endpoint. This technology gives you remote access to corporate applications and other resources.
13. Wireless Security
With the introduction of the mobile office culture, access points and wireless networks have become entry points for security breaches. Wireless security makes it difficult for anyone with unauthorized access to the network to cause damage to the computer’s data.
14. Web Security
This type of network security is used to determine levels of user access, identify vulnerabilities in applications, and differentiate between unauthorized and authorized users. Web security helps protect an organization’s sensitive data from being compromised.
