Final answer:
An organization can deploy a firewall, VPN, or intrusion prevention systems (IPS) to prevent unauthorized external access to its internal network.
Step-by-step explanation:
In order to prevent unauthorized external access to its internal network, an organization can deploy a firewall as a security solution. A firewall acts as a barrier between an internal network and the external network, monitoring and controlling incoming and outgoing traffic based on predetermined security rules.
Another security solution that can be deployed is a virtual private network (VPN). A VPN creates a secure and encrypted connection over a public network, allowing authorized users to access the internal network from remote locations.
Lastly, an organization can implement intrusion prevention systems (IPS). IPSs are designed to detect and prevent any malicious activities or attacks on the network by monitoring network traffic and blocking potential threats in real-time. They can help protect against unauthorized access and reduce the risk of data breaches.
To prevent unauthorized external access to its internal network, an organization can deploy a firewall, which serves as a barrier between its internal and external networks by filtering traffic based on security rules. Other complementary measures include Virtual Private Networks (VPNs) and Intrusion Prevention Systems (IPS).
An organization can deploy a firewall as a security solution to prevent unauthorized external access to its internal network. A firewall can be hardware-based, software-based, or a combination of both, and it works by filtering incoming and outgoing network traffic based on an established set of security rules. Its purpose is to block malicious traffic like cyber-attacks and unauthorized access, while allowing legitimate traffic to pass through.
Additionally, organizations may also make use of Virtual Private Networks (VPNs), which encrypt internet traffic, and Intrusion Prevention Systems (IPS), that actively monitor for suspicious activity and block potential threats. It’s crucial for organizations to regularly update and configure these security measures to adapt to new threats and maintain strong security protocols.
