Key Cybersecurity Concepts: MFA, SIEM, SOC, Red Teams, and More
Most businesses understand the need for robust cybersecurity protections, but they don’t necessarily understand all of the key concepts and technologies involved.
This is understandable, as it’s a specialist field and businesses usually bring in third-party cybersecurity companies or appoint an in-house person/department to handle that side of things.
However, it can be useful to understand some of the central concepts that underpin your company’s cybersecurity strategy.
We’ll explore these here, including MFA, SIEM, SOC, Red Teams and other essential terms – in easy-to-understand, jargon-free explanations.
What Is MFA in Cybersecurity?
The first key concept you need to know about is Multi-Factor Authentication (MFA). You’re likely to have come across this in your personal life – for example, when you sign into your mobile banking app on your smartphone.
But what is multi-factor authentication in cyber security? Essentially, it’s the process of checking that the user is who they claim to be when logging into a secure system. In the past, authentication was limited to just one layer – a password. But as passwords can be guessed, stolen or reused, today’s systems add multiple layers to bolster protection for accounts and systems.
This means that two or more different types of verification are required before access is granted. These typically fall into three categories:
- Something you know – such as a password or PIN
- Something you have – such as a smartphone, authentication app or hardware token
- Something you are – biometric data like a fingerprint or facial recognition.
Here’s how it works in practice – a user accesses a secure company system using their password, then confirms their identity using a one-time code sent to their work phone. This extra check means that even if a password is compromised or a device lost or stolen, a potential attacker would not be able to complete all the MFA checks and access the system.
MFA is really effective in the battle to keep both personal and business accounts secure. It’s become the norm for everything from email systems and cloud applications to VPNs and remote access tools.
What Is SIEM and How It Works
So, what is SIEM in cybersecurity? SIEM stands for Security Information and Event Management. This is a system which collects, analyses and helps respond to security threats in real time.
Every device, server, firewall and application within an organisation generates log data. This includes things like file access, records of logins and network activity.
On their own, these logs are hard to interpret, but SIEM platforms bring them together in one place. This kind of system aggregates data from across the whole IT environment, providing a centralised view so that anomalies and suspicious patterns can be detected.
For example, repeated failed logins, unusual access times or a user logging in from two countries within a few minutes.
It generates alerts and reports, so that security teams can investigate immediately and safeguard the system before a potential threat turns into a major breach.
What Is a SOC in Cybersecurity?
Now we come to SOC, which stands for Security Operations Centre. This is where cybersecurity monitoring and response happens. If SIEM is the technology, then SOC is the people and processes behind it.
SOC is a dedicated function for managing cybersecurity, which can be either outsourced or in-house. It monitors systems 24/7, investigates alerts and response to any security incidents flagged up by SIEM systems or staff members. This might be malware, phishing, unauthorised access or another threat.
Due to the cost and complexity of building an internal team of cybersecurity experts, many modern organisations choose to use managed SOC and cybersecurity services. These offer round-the-clock protection without major upfront or ongoing expenses.
What Red Teams Do in Security Testing
Ever wondered – what is a Red Team in cybersecurity? The rather thrilling sounding ‘Red Teams’ is a term used to describe security professionals who simulate the actions of real cyber attackers. They can be thought of as ethical hackers, whose job is to break into an organisation’s systems legally and safely.
Why would they do this? The main aim is to identify weak points in a company’s cybersecurity defences. The experts put themselves in the shoes of a potential attacker, using the latest methods and tricks they’d use to break into a system. Only by doing this can potential attacks be predicted and prevented, as gaps in security can be closed and proactive measures put in place.
Red Teams usually operate with a specific goal in mind, such as gaining access to sensitive data or bypassing security controls. They test out everything from networks and applications to detection, escalation and incident response processes.
Other Essential Cybersecurity Terms Explained
Lastly, here are some other cybersecurity terms you might need to know about.
What Is a PUP in Cybersecurity?
A Potentially Unwanted Program (PUP) is software that isn’t outright malicious, but can still cause problems. Common examples include adware, browser toolbar or bundled applications that affect performance, privacy or user experience.
What Is ACL in Cybersecurity?
An Access Control List (ACL) defines who is allowed to access specific resources and what actions they can perform.
What Is DLP in Cybersecurity?
Data Loss Prevention (DLP) refers to tools and policies designed to stop sensitive data from being leaked, lost or misused.
What Is EAP in Cybersecurity?
Extensible Authentication Protocol (EAP) is a framework used for secure authentication, especially in enterprise Wi-Fi and network access scenarios. It supports multiple authentication methods and integrates with identity management systems.
What Is SOAR in Cybersecurity?
Security Orchestration, Automation, and Response (SOAR) platforms help security teams automate repetitive tasks and coordinate responses across tools.
