What is prevention software?
Part of the Zero Trust strategy includes implementing a network defense plan that protects data and applications to make them more secure. Using prevention devices and software helps organizations reach this goal.
Prevention devices or software well known for securing networks are:
- Firewalls
- Virtual private networks (VPN)
- Antivirus software
- Routine device updates
Firewalls
A firewall is a network security device that filters incoming and outgoing network traffic. Firewalls prevent unwanted network traffic and malicious software from reaching the network. Networks that don’t use a firewall accept all connection requests from any device anywhere, which is a huge security risk.
VPNs
A virtual private network (VPN) is a secure connection from one network to another. A VPN extends a private network across a public network by creating an encrypted tunnel. Data transferred within this tunnel is hidden from third parties. For example, organizations can provide a VPN connection to end users who need to sign into the company’s network from locations that don’t have secure connections, like coffee shops or airports. A VPN increases security by making sure that:
- The user’s location stays private.
- Data is encrypted.
- Identity is anonymous.
Antivirus software
Antivirus software is also an essential component of network security. Antivirus software protects the device against malicious software coming from the internet. Antivirus software works by using the main actions of detection, identification, and removal of threats.
