IPsec VPN

An IPsec VPN uses the IPsec protocol suite to establish a secure communication channel over the internet, encrypting data for privacy and integrity.

Latency

In cybersecurity, latency refers to the time delay between a user’s action and a system’s response. Low latency is often crucial in real-time security monitoring.

Malware

Software designed to infiltrate or damage computer systems. Types include viruses, worms, ransomware, and spyware, among others.

Multi-Factor Authentication

Multi-factor authentication (MFA) enhances security by requiring two or more forms of verification before granting access, such as a password and a mobile OTP.

Network Intrusion Prevention System

Also known as NIPS, this system monitors and controls network traffic to prevent unauthorized access and attacks, often using signature-based detection.

Next Generation Firewall (NGFW)

A next generation firewall (NGFW) offers advanced features like application-level inspection, intrusion prevention, and identity-based controls for enhanced security.

NGFW Vs. WAF

This comparison highlights the differences between Next Generation Firewalls and Web Application Firewalls, particularly in the scope and depth of protection they offer. WAF focuses on application layer traffic.

Port Scanning

The practice of probing network ports to identify open services and potential vulnerabilities, often used in security assessments and penetration testing.

SASE

Secure Access Service Edge (SASE) combines network security functions with wide-area networking (WAN) capabilities to support dynamic, secure access to organizational assets.

SIP Proxy

An intermediary server that routes SIP traffic, providing security and performance benefits, such as preventing unauthorized access and reducing latency.

Universal Access Controller

A universal access controller manages authentication and access across various types of network connections, often used in large or complex networks for centralized control.

VPN Client

Software that enables a secure connection to a Virtual Private Network, encrypting data for secure communication over the internet.

Zero-Day Threat

A vulnerability that is unknown to the vendor and unpatched, posing a high risk as there are no specific defenses against it.

Anti-Spam

Anti-spam software filters and blocks unwanted emails to reduce the risk of phishing attacks. It uses algorithms and blacklists to identify spam, helping to keep inboxes clean and secure.

Bare Metal Disaster Recovery

This involves restoring a system directly onto hardware, bypassing the operating system. It is a quick way to recover from system failures, ensuring minimal downtime.

Botnet C&C Protection

This refers to security measures designed to block communication between botnets and their command-and-control servers, disrupting their malicious activities.

Bug

A bug is a software flaw or error that can be exploited to gain unauthorized access or perform unintended actions, requiring patches for resolution.

Connection Flood

A type of DoS attack that overwhelms a network or service by opening an excessive number of connections, rendering it unusable.

Data Flow Diagram

A data flow diagram visually represents how data moves through a system. It’s used in security to identify potential points of vulnerability.

Data Loss Prevention (DLP)

DLP technologies monitor and control data transfers, preventing unauthorized export or leakage of sensitive information from the network.

DDoS (Distributed Denial-of-Service)

DDoS attacks overwhelm a target service or network by flooding it with high volumes of traffic from multiple sources, making it inaccessible to legitimate users.

Device Control

Device control involves managing the access and functionality of hardware devices connected to a network, such as USB drives, to prevent data leaks or malware infection.

Disaster Recovery / Business Continuity

This refers to strategies and plans to ensure that essential business functions continue during and after a disaster, encompassing both recovery and ongoing operations.

Domain Name System

Is the phonebook of the internet, translating human-readable domain names into IP addresses that computers can understand.

Failover

Failover is the automatic switching to a backup system or component in the event of a failure, ensuring uninterrupted service.

Firewall Policy

A set of rules that dictate what kind of network traffic is allowed or blocked, guiding the firewall in making security decisions.

Intelligent Policy Operation

Intelligent policy operation involves automated adjustments to security policies based on real-time analysis, often using machine learning or AI for decision-making.

IP Reputation

A score or rating that indicates the trustworthiness of an IP address, based on its history of malicious or benign activity.

IPv6 (Internet Protocol Version 6)

IPv6 is the latest version of the Internet Protocol, designed to address the limitations of IPv4, such as the availability of IP addresses.

Malicious Traffic

Malicious traffic refers to network traffic involved in cyberattacks or unauthorized activities, often detected and blocked by security solutions.

Management Console

A centralized interface for configuring and monitoring security solutions, often providing dashboards, alerts, and reporting features.

Multi-Homing

Multi-homing involves connecting a network to multiple Internet Service Providers (ISPs) to ensure redundancy and uninterrupted service.

Network Security

Network security involves measures to protect the integrity, confidentiality, and availability of data as it is transmitted across or accessed from network systems.

NGFW Vs. Traditional Firewall

This comparison focuses on the advanced capabilities of NGFWs, such as deep packet inspection and application awareness, as opposed to basic packet filtering in traditional firewalls.
