Firewall Terms Flashcards
Distributed Denial of Service (DDoS) protection refers to the measures taken to defend a network or application from malicious attempts to overwhelm it with a massive amount of traffic. The Juniper firewall employs various techniques like rate limiting, traffic profiling, and behavioral analysis to identify and mitigate DDoS attacks, ensuring that legitimate traffic can still access network resources.
DDoS Protection
Zero-day attack prevention involves safeguarding against exploits that target vulnerabilities unknown to the vendor or the public. Juniper firewalls use advanced threat intelligence, anomaly detection, and heuristics to identify and block such attacks before they can cause harm.
Zero-Day Attack Prevention
Application control is the ability to regulate and manage the usage of specific applications or application categories within the network. Juniper firewalls offer granular control over which applications are allowed or blocked based on predefined policies, enabling organizations to optimize network performance and enhance security.
Application Control
Access control refers to managing and restricting user access to network resources based on user identity, roles, and permissions. Juniper firewalls provide robust access control mechanisms, such as firewall rules, authentication, and authorization, to ensure that only authorized users can access specific network segments or services.
Access Control
This feature allows the firewall to inspect and analyze encrypted traffic (such as SSL/TLS) for potential threats or malicious content. The Juniper firewall decrypts encrypted traffic, examines its contents, and then re-encrypts it before forwarding it to the destination, thus enhancing security without compromising privacy.
Encrypted Traffic Analysis
Regular firmware updates are essential to keep the firewall up-to-date with the latest security patches, bug fixes, and feature enhancements. Juniper provides timely firmware and general updates to ensure that the firewall remains resilient against emerging threats.
Firmware and General Updates
Deep Packet Inspection (DPI) is a technique used to inspect the contents of data packets at a granular level. Juniper firewalls employ DPI to analyze network traffic thoroughly, identify potential threats, and enforce security policies based on application signatures, traffic patterns, and other parameters.
Deep Packet Inspection
User and device identification involve recognizing individual users and devices connecting to the network. Juniper firewalls can associate user identities with IP addresses or MAC addresses, enabling more precise access control and monitoring user-specific activities.
User and Device Identification
Intrusion Prevention System (IPS) and Intrusion Detection System (IDS) functionalities are used to detect and prevent unauthorized or malicious activities within the network. Juniper firewalls receive daily signature updates to stay current with the latest threat definitions, enhancing their ability to detect and block new threats effectively.
Intrusion Prevention and Intrusion Detection with Daily Signature Updates
Juniper firewalls provide centralized management through cloud-based or on-premises platforms. These management tools allow administrators to configure, monitor, and analyze firewall performance, security events, and other essential metrics from a single interface.
Cloud-Based/On-Premises Management, Reporting, and Analytics
Configurable alerts enable administrators to set up notifications for specific events or security incidents detected by the firewall. These alerts can be sent via email, SMS, or other communication channels, ensuring that administrators are promptly informed of potential threats.
Configurable Alerts
Sandbox testing involves running potentially suspicious files or applications in an isolated environment to analyze their behavior without risking the network’s security. Juniper firewalls can utilize sandboxing to identify and mitigate zero-day threats and other advanced malware.
Sandbox Testing
SSL Inspection (also known as SSL Decryption) is the process of decrypting and inspecting encrypted SSL/TLS traffic to detect and prevent threats hidden within it. Juniper firewalls support SSL inspection to enhance security even for encrypted communications.
SSL Inspection/Decryption
Network Address Translation (NAT) and Virtual IP (VIP) support enable the Juniper firewall to map private IP addresses to public IP addresses and forward traffic to internal resources efficiently. This aids in concealing internal network structures and providing an additional layer of security.
NAT and/or Virtual IP Support
Juniper firewalls support Virtual Private Network (VPN) connections, allowing secure and encrypted communication between remote sites or individual users over the internet. VPNs help protect data privacy and enhance network security for remote access scenarios.
