Network Security
| Question | Answer |
|---|---|
| is the protection of the underlying networking infrastructure from unauthorized access, misuse, or theft. It involves creating a secure infrastructure for devices, applications, users, and applications to work in a secure manner. | Network Security |
| combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. | Network security |
| How does Network Security Work? | enterprises have much to gain by strengthening their network protections |
| Strong, robust security measures help ensure your data always stays protected. | Reduced cyber risk |
| Eliminating threat vectors ensures sensitive information is shielded from unauthorized access while traversing the network, thereby safeguarding customer data, and maintaining compliance. | Enhanced data privacy |
| Protected networks are more resilient against potential disruptions and experience minimal downtime, leading to optimal productivity. | Improved business continuity |
| Security prevents bad actors from disabling the network, ensuring critical resources are always readily available. | Better network performance |
| Switching ensures adequate security at the network edge by facilitating traffic filtering and access control at the port level, allowing administrators to enforce policies on granular network segments. | Ethernet switches: |
| Wireless APs implement encryption protocols and authentication mechanisms, protecting data in transit. They also support access control lists (ACLs), restricting unauthorized devices from connecting to the network | Wi-Fi access points (AP) |
| 5G and LTE gateways are key to redundant and primary links to branch offices and campuses alike. Housing these devices under the same security umbrella as the rest of the network ensures common configuration, thereby reducing the attack surface. | Gateway |
| Types of Network Security Solutions | Firewalls Intrusion Prevention Systems (IPS) Antivirus and Sandboxing Web and DNS Filtering Remote Access VPNs Network Access Control (NAC) |
| a device that monitors, filters, and controls incoming and outgoing network traffic based on predefined security rules. | Firewalls |
| detect, and block known and suspected threats before they can impact the network core or devices at its edge. | Intrusion Prevention Systems (IPS) |
| are key to determining whether a file is malicious. | Antivirus and Sandboxing |
| filtering allows organizations to stop domain-based attacks, such as DNS hijacking, tunneling, etc. | Web and DNS Filtering |
| allow users to securely access the corporate network from outside their organization’s office. | Remote Access VPNs |
| Is a security solution that uses a set of protocols to keep unauthorized users and devices out of a private network or give restricted access to the devices which are compliant with network security policies. | Network Access Control (NAC) |
| Security Devices | Ethernet Switch Wi-Fi Access Point Gateway |
| Which attack floods a network with traffic? | DDoS |
| Which tool analyzes suspicious files safely? | Sandboxing |
| What does NAC stand for? | Network Access Control |
| Which security solution protects against malware? | Antivirus |
