Cybersecurity 101

In today’s digital world, cybersecurity is essential. At WatchGuard, we break down key cybersecurity topics with clear explanations, practical examples, and proven best practices. Whether you want to learn about network security, endpoint protection, identity management, or cyber threats—start your journey with Cybersecurity 101.

B

Bring-Your-Own-Device (BYOD)

A common practice whereby employees can use their personally owned devices, like smartphones, laptops, and tablets for work purposes rather than company-issued devices. Increases exposure to malware, data leakage, and credential theft.

D

Dark Web Credential Monitoring

Tools that can scan stealer logs, criminal forums, and third-party breaches on the dark web for your organization's exposed passwords. By providing visibility into exposed corporate credentials, it enables faster response and risk mitigation.

E

Endpoint Agent Consolidation

Many endpoint security systems have multiple agents (lightweight services that run in the background to automate monitoring and control). A more secure, modern approach is to have a single agent that drives your entire security ecosystem, leading to decreased CPU load, bandwidth use, and operational complexity.

F

False Positive

An alert that incorrectly flags legitimate activity or files as malicious threats. Can be caused by overly sensitive monitoring tools or misconfigured rules.

M

Managed Detection and Response (MDR)

A fully managed cybersecurity service that continuously monitors your IT environment, including endpoints, networks, cloud applications, and user accounts, to detect and stop threats before they cause harm. Unlike traditional tools, which only alert users to possible issues, MDR combines advanced AI-driven analytics and human expertise to investigate and respond to attacks in real time.

N

Network Detection and Response (NDR)

Provides continuous, real-time monitoring and analysis of network traffic to detect, investigate, and stop malicious threats. Can be deployed as an appliance or through the cloud. Advantage of cloud-native NDR: no new hardware to manage, no sensors, no packet capture infrastructure, eliminating cost and complexity of hardware-based NDR.

North/South Traffic

Traffic that moves between an organization's network perimter and the outside world (e.g., the Internet, a user's device). See East/West Traffic

R

Remote Monitoring and Management (RMM)

The technology IT and MSPs use to centrally monitor, secure, and maintain networks, servers, and devices (endpoints). Modern RMM solutions support both on-premises and cloud infrastructure monitoring and remote smart device management to improve efficiency and cost.

S

Secure Access Service Edge (SASE)

A cloud-based framework that converges networking (like SD-WAN) and security functions (like Secure Web Gateway, CASB, Firewall as a Service, Zero Trust Network Access) into a single, unified service to securely connect users, devices, and applications anywhere.

Security Operations Center (SOC)

A security team that acts as an organization's central command, bringing together its entire IT infrastructure. High costs, complexity, and staff-intensive requirements make deploying an internal SOS unrealistic for all but the largest enterprises. Managed service providers (MSPs) are key to providing critical SOC services for smaller and mid-market businesses.

SIEM

Stands for Security Information and Event Management. Provides real-time analysis of security alerts from applications and network hardware. The main downsides of SIEM products are their complexity and high cost, leading to difficult setup, alert fatigue, significant resource needs (expertise, hardware), and long deployment times. XDR is the smarter choice for MSPs and lean IT teams.

Single Sign-On (SSO)

An authentication method in which one login (typically with username and password) allows access to multiple applications and services, providing convenience for users and better and centralized oversight for IT teams.

Software as a Service (SaaS)

A cloud-based model where software applications are delivered over the Internet, typically via a web browser, on a subscription basis, with the provider managing all underlying infrastructure, maintenance, and updates.
