Network security provides protection for your network infrastructure from intrusions and unauthorized access and data theft. Network security involves creating a safe network infrastructure for your devices and authorized users to work in a secure environment. There are various types of network security, and we recommend that you learn about them for your further network wellbeing.
Antivirus and anti-malware software
This is software that protects a system against malware which could be a virus, Trojan, ransomware, or spyware. Malware is a risk, especially because it can stay hidden in your system for a long while without being noticed readily to attack your system. An antivirus or anti-malware software scans your system for malware and tracks any files affected by the hostile guests and gets rid of them or inhibits their intention.
This is a need to have some security protection because applications are created every day, and they may not be perfect. Applications installed in your system could have weaknesses and backdoors which hackers can or could use to access your data. Application security, as the name suggests, protects your applications.
Network Access Control
Commonly known as NAC, this is a feature that allows you to control who can and can’t access your network. Most operating systems have this as an inbuilt option. You are eligible to control which devices or users are allowed into your network. You also can block unauthorized users out of your network by enabling certain security policies like blocking determined devices and controlling what a user can do within your network, say if they can read or write or both.
Furthermore, you can also use firewalls, which create a barrier between your network and other networks on the internet. You can also use the firewall to control user’s internet operation and block websites that are potentially a threat.
In an era where email is an integral part of communication, especially in business, its security is very important. Email platforms can have gateways for a security breach. Hackers can access personal information and do so much damage, such as blackmail, or send false emails on your behalf to your clients, for instance. One can also send an email with links that can prompt a user to malware sites. An email security application is important because it will block these attacks, control what is sent, and even inform you if an email is safe to open.
Virtual Private Network
Commonly known as VPN, it makes a system highly secure, as this uses encryption methods for authentication and ensures secure data traffic over the internet to a remote device or network. VPNs use IPsec to authenticate the communication between the device and network.
Intrusion Prevention Systems(IPS)
An IPS scan the network traffic to block attacks in real-time by co-relating the global threat intelligence to block malicious activities and track suspected files and malware across a network to prevent the spread of malware outbreaks and system reinfection.
This involves a wide set of technology and policies as well as applications that protect online IP, services, applications, and other data by shielding a user against any threats when they do access the internet and securing your data and applications in the cloud
Data Loss Prevention(DLP)
DLP technology and policies prevent users in a network from uploading, forwarding, or printing sensitive information in an unsafe environment. This is used especially by organizations to ensure their staff do not send sensitive information outside the network
This controls user’s internet usage, blocks web-based threats, and denies any access to malicious websites. It can involve any steps that a user takes to protect their own website.
