Active threat response CBT (Computer-Based Training) constitutes a pivotal component in modern cybersecurity frameworks, actively equipping security personnel with skills to neutralize threats. Incident response teams utilizes active threat response CBT module for simulating real-world scenarios to hone their skills. The simulations facilitate a deeper understanding of threat actor tactics that allow cyber security analysts to respond effectively. Security operation center personnel benefits from this training through improving their capabilities in identifying and mitigating cyber threats.

The Cybersecurity Landscape is Changing, Fast!

Remember the good old days of cybersecurity? You know, when a firewall and a decent antivirus were enough to keep the bad guys out? Yeah, me neither. The digital world has evolved, and so have cyber threats. We’re not just dealing with script kiddies anymore; we’re up against sophisticated, well-funded adversaries who are constantly developing new and innovative ways to infiltrate our systems. It’s like trying to play Whac-A-Mole, but the moles are ninjas with PhDs in hacking.

Traditional, reactive security measures – think of them as waiting for the alarm to go off before calling the fire department – simply aren’t cutting it anymore. By the time you detect an intrusion, the damage is often already done. Data breaches, ransomware attacks, and other cyber incidents can have devastating consequences for businesses of all sizes. We need to shift from a reactive to a proactive approach.

Enter Active Threat Response (ATR): Your 24/7 Cybersecurity Bodyguard

So, what’s the solution? Enter Active Threat Response (ATR). Think of it as the cybersecurity equivalent of a super-powered immune system. ATR is a proactive security strategy that goes beyond simply detecting and responding to threats after they’ve already penetrated your defenses. It actively hunts for threats, analyzes their behavior, and takes steps to mitigate them in real-time, before they can cause significant damage. It’s like having a security team that doesn’t just wait for the burglar alarm, but actively patrols the perimeter, looking for suspicious activity.

ATR: Real-Time Threat Mitigation and a Robust Security Posture

ATR leverages a combination of cutting-edge technologies and skilled security professionals to provide a more robust and resilient security posture. It enables organizations to:

• Identify threats earlier: By proactively hunting for malicious activity, ATR can detect threats that might otherwise go unnoticed by traditional security tools.
• Respond faster: ATR automates many of the tasks involved in incident response, enabling security teams to contain and eradicate threats more quickly.
• Reduce the impact of attacks: By mitigating threats in real-time, ATR can minimize the damage caused by successful cyberattacks.
• Adapt to evolving threats: ATR leverages threat intelligence and machine learning to stay ahead of emerging threats and adapt to changing attack patterns.

The Core Components of ATR: A Sneak Peek

ATR isn’t a single product or technology; it’s a holistic approach that integrates various security tools and processes. We’ll dive deeper into these later, but here’s a quick preview:

• Cyber Threat Intelligence (CTI): Provides insights into the latest threats and attack techniques.
• Security Information and Event Management (SIEM): Aggregates and analyzes security logs from various sources.
• Security Orchestration, Automation, and Response (SOAR): Automates security tasks and incident response workflows.
• Endpoint Detection and Response (EDR): Monitors endpoints for malicious activity.
• Network Detection and Response (NDR): Analyzes network traffic for suspicious patterns.

The Foundation of ATR: Understanding Key Concepts

Think of Active Threat Response (ATR) like building a super-secure fortress. You can’t just slap up some walls and call it a day, right? You need a solid foundation, a well-thought-out plan, and some serious tech to keep the bad guys out. That’s where these key concepts come in! They’re the bedrock of a successful ATR strategy, each playing a vital role in keeping your digital kingdom safe. So, let’s dive in and see what makes this fortress so formidable.

Cyber Threat Intelligence (CTI): The Crystal Ball of Cybersecurity

Imagine having a crystal ball that shows you what attacks are coming your way. That’s essentially what Cyber Threat Intelligence (CTI) does! It’s all about gathering information on the latest threats, analyzing it, and then sharing it with your security team before the attacks happen.

• It’s the insight needed to anticipate and prevent attacks! We are talking about understanding the tactics, techniques, and procedures (TTPs) of threat actors. Think of it as knowing your enemy inside and out.

• Why is it so important? Because knowledge is power! Gathering, analyzing, and sharing timely and relevant threat intel helps you make smart security decisions. You can proactively adjust your defenses, patch vulnerabilities, and train your team to recognize the signs of an attack.

• Example Time! Let’s say CTI reveals a new phishing campaign targeting your industry. With that intel, you can warn your employees, update your email filters, and monitor for suspicious activity. Boom! Attack averted.

SIEM: The Central Nervous System for Security Data

Now, picture a central hub where all your security data comes together. That’s your Security Information and Event Management (SIEM) system. It’s like the central nervous system of your security infrastructure, collecting logs and events from every corner of your IT environment.

• SIEMs are data vacuum cleaners! They suck up logs from servers, network devices, applications, and everything in between. Then, they analyze this data to find patterns and anomalies that could indicate a threat.

• The real magic is visibility. SIEMs give you a bird’s-eye view of your entire security landscape. You can see what’s happening in real-time, identify potential problems, and respond quickly.

• Rules are your friend! SIEMs use rules and correlation logic to identify suspicious activity. For example, if someone tries to log in to multiple accounts from different locations in a short time, that’s a red flag that the SIEM will pick up.

SOAR: Automating the Fight Against Threats

Okay, so you’ve got threat intelligence, and you’re collecting all this security data. What’s next? That’s where Security Orchestration, Automation, and Response (SOAR) comes in! SOAR is like the superhero sidekick that automates your security tasks.

• SOAR platforms are workflow wizards! They automate repetitive tasks like incident response, threat investigation, and remediation. This frees up your security team to focus on more complex issues.

• Speed and efficiency are the name of the game! SOAR can significantly reduce response times and improve the overall efficiency of your security operations.

• Use Case Bonanza! Think automated phishing response (automatically quarantining suspicious emails), malware containment (isolating infected systems), and vulnerability patching (triggering updates based on identified risks). The possibilities are endless!

EDR: Protecting the Front Lines at the Endpoint

Endpoints, endpoints, endpoints! These are the battlegrounds where many attacks happen. That’s where Endpoint Detection and Response (EDR) comes to the rescue! It’s your last line of defense.

• EDR solutions act like bodyguards for your endpoints! They constantly monitor devices for malicious activity and provide real-time threat detection.

• When something suspicious happens, EDR enables your security team to jump into action. They can investigate the threat, isolate the infected device, and prevent the attack from spreading.

• Behavioral analysis and machine learning are the brains behind EDR. These technologies help detect even the most advanced threats, like fileless malware and zero-day exploits. It learns the regular behaviour of your network, and flags anything out of the ordinary.

NDR: Watching the Wires for Suspicious Network Activity

But wait, there’s more! We also need to keep an eye on the network itself. That’s where Network Detection and Response (NDR) comes in! It’s like having a security camera system for your network traffic.

• NDR solutions are network traffic analysts! They analyze network traffic to identify and mitigate network-based threats like lateral movement, data exfiltration, and command-and-control activity.

• Network Traffic Analysis (NTA) and Anomaly Detection are key here. NDR looks for unusual patterns in network traffic that could indicate a threat. This could be anything from a sudden spike in traffic to a server communicating with a known malicious IP address.

• Lateral movement alert! If an attacker gains access to one system, they’ll often try to move laterally to other systems on the network. NDR can detect this activity and stop the attacker in their tracks.

So, there you have it! The core components of an Active Threat Response strategy. By combining CTI, SIEM, SOAR, EDR, and NDR, you can build a truly proactive and resilient security posture. Time to fortify that digital kingdom!

Essential Technologies for Active Threat Response

In the realm of Active Threat Response (ATR), it’s not just about having the right strategies; it’s also about wielding the right tools! Think of ATR as a superhero team – each member has unique gadgets and skills that, when combined, make them an unstoppable force. Let’s dive into the tech toolbox that makes ATR tick.

• • IDS/IPS: Gatekeepers of the Network

  Imagine your network as a medieval castle. You need vigilant guards at the gates to spot trouble, right? That’s where Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) come in. The IDS is like a security camera system, constantly monitoring network traffic for suspicious activity and raising an alarm when something fishy is detected. The IPS takes it a step further; it’s like having those guards actively stop intruders in their tracks!

  • • IDS vs. IPS: Understanding the Difference

    The key difference? IDS detects and alerts, while IPS detects and prevents. Think of it this way: the IDS sees a burglar and calls the police; the IPS sees the burglar and slams the door shut. IDS are PASSIVE, while IPS are ACTIVE.

  • • Strategic Placement: Location, Location, Location!

    Where you place your IDS/IPS is crucial. Putting them at the perimeter of your network helps catch external threats early on. Internal placement helps spot lateral movement—when an attacker has already breached the outer defenses and is trying to move around inside. It’s like placing guards both at the castle gates and inside the halls.

  • • Keeping Them Sharp: Signature Updates and Custom Rules

    IDS/IPS rely on signatures – think of them as “fingerprints” of known attacks. To stay effective, you need regular signature updates to recognize the latest threats. Plus, creating custom rules tailored to your specific environment can help you catch unique or targeted attacks. It’s like updating your guards’ training manual to keep them ahead of the curve.

• • Honeypots and Deception Technology: Turning the Tables on Attackers

  Ever watched a spy movie where they set a trap for the bad guys? That’s essentially what honeypots and deception technology do in the cyber world!

  • • Luring the Enemy: What are Honeypots?

    Honeypots are decoy systems designed to attract attackers. They look like valuable targets but are actually isolated and monitored. When an attacker interacts with a honeypot, it’s a huge red flag. It provides valuable intelligence about their tactics, techniques, and procedures (TTPs), all while diverting them from real assets. It is like leaving bait to lure the enemy out.

  • • Creating a False Reality: Deception Technology

    Deception technology takes it up a notch by creating an entire deceptive environment. It’s like filling your network with fake files, credentials, and servers, all designed to trick attackers. Any interaction with these deceptive assets is a clear sign of malicious activity. Deception technology greatly enhances threat detection capabilities.

  • • Types of Honeypots: High-Interaction vs. Low-Interaction

    Honeypots come in different flavors. High-interaction honeypots are complex systems that mimic real production environments, providing attackers with a realistic experience. Low-interaction honeypots are simpler, emulating only certain services or applications. The best choice depends on your goals and resources.

• • Firewalls: The First Line of Defense

  No security conversation is complete without mentioning firewalls! They’re the OG guardians of the network perimeter.

  • • The Gatekeeper: Controlling Network Traffic

    Firewalls control network traffic based on a set of predefined rules. They act as a barrier, allowing only legitimate traffic to pass through while blocking anything that doesn’t meet the criteria. It is like having a bouncer checking IDs at the entrance of a club.

  • • Next-Generation Firewalls (NGFWs): Evolving with the Threats

    Firewalls have evolved over time. Next-Generation Firewalls (NGFWs) offer advanced features like deep packet inspection, application awareness, and intrusion prevention capabilities. They can identify and block threats that traditional firewalls might miss.

  • • Configuration is Key: Rule Management and Best Practices

    A firewall is only as good as its configuration. Proper firewall configuration and rule management are crucial for maintaining effective security. Regularly review and update your firewall rules to ensure they’re still relevant and not creating unnecessary vulnerabilities.

In summary, these technologies form the backbone of an effective Active Threat Response strategy. They work together to detect, prevent, and respond to threats in real time, giving you the upper hand in the ongoing battle against cybercrime.

ATR in Action: Key Processes for Effective Threat Mitigation

Think of Active Threat Response (ATR) as the special ops team for your cybersecurity. It’s not enough to just react to alarms; you need to proactively hunt down threats, contain them, and learn from every encounter. Let’s dive into the critical processes that make up a comprehensive ATR strategy, showing how they each play a vital role in keeping your digital kingdom safe.

Vulnerability Management: Proactive Weakness Detection

Imagine your IT infrastructure as a medieval castle. Before any enemy can even think about attacking, you would want to know where the weak spots in your walls are, right? That’s exactly what vulnerability management is all about. It’s the art and science of identifying and addressing vulnerabilities in your systems and applications before the bad guys do.

• Why it matters: Think of it this way: every piece of software has potential chinks in its armor. Vulnerability management helps you find those weaknesses so you can patch them up before they become a major security incident.
• How it works: Regular vulnerability scanning and patching are the name of the game. You scan your systems to identify vulnerabilities, then you apply patches to fix those issues. It’s like giving your castle a regular check-up and patching any cracks you find.
• Tools of the trade: Vulnerability management tools and frameworks are your best friends here. They automate the scanning process and provide you with reports on your vulnerabilities.

Penetration Testing (Ethical Hacking): Simulating Real-World Attacks

So you’ve patched your systems and think you’re secure? Time to put that to the test by doing a penetration test, it’s when you hire ethical hackers and say go and attack us! Consider it a fire drill for your cybersecurity.

• Why it matters: Penetration testing simulates real-world attacks to identify security weaknesses that automated scans might miss. Think of it as hiring someone to try and break into your castle so you can see where your defenses are lacking.
• How it works: Penetration testing involves several phases, from reconnaissance (gathering information about your systems) to exploitation (attempting to gain access to your systems). Ethical hackers will try to exploit any vulnerabilities they find to demonstrate the impact of a successful attack.
• What you’ll find: Penetration tests can uncover a wide range of vulnerabilities, from weak passwords to misconfigured systems. The results of the penetration test should be used to improve your defenses and prevent real-world attacks.

Digital Forensics: Uncovering the Truth After an Incident

Ok so if a breach does occur it is important to get a CSI (cyber security investigations) team in to understand what happened. Digital forensics is like being a cyber detective. It’s all about collecting and analyzing digital evidence after a security incident to understand what happened and who was responsible.

• Why it matters: Digital forensics helps you understand the scope and impact of attacks. By analyzing the evidence, you can determine how the attackers gained access to your systems, what data they accessed, and what actions they took.
• How it works: Digital forensics involves collecting data from various sources, such as hard drives, network logs, and memory dumps. This data is then analyzed to reconstruct the events that occurred during the incident.
• Tools of the trade: Digital forensics investigations use specialized tools and techniques to analyze digital evidence. These tools can help you recover deleted files, identify malware, and track the activity of attackers.

Malware Analysis: Understanding the Enemy

“Know thy enemy,” as the saying goes. Malware analysis is the process of dissecting malicious software to understand its behavior and develop effective countermeasures.

• Why it matters: By understanding how malware works, you can develop strategies to detect and prevent infections. You can also use malware analysis to create signatures that can be used to identify and block malicious software.
• How it works: There are two main types of malware analysis: static and dynamic analysis. Static analysis involves examining the code of the malware without executing it. Dynamic analysis involves running the malware in a controlled environment and observing its behavior.
• The end goal: The goal of malware analysis is to understand how the malware works so you can develop effective countermeasures. This information can be used to create signatures, improve detection rates, and prevent future infections.

Containment: Limiting the Damage

Once a threat is detected, the next step is to stop the bleeding. Containment is the process of isolating compromised systems to prevent further damage.

• Why it matters: Containment limits the scope of an incident and prevents attackers from spreading to other systems. By isolating compromised systems, you can prevent further data loss, system damage, and reputational harm.
• How it works: There are several containment strategies you can use, such as network segmentation, application sandboxing, and disabling compromised accounts. The goal is to isolate the compromised systems while minimizing the impact on legitimate users.
• Automated Containment: SOAR platforms can automate containment measures, such as isolating compromised systems or blocking malicious IP addresses. This allows you to respond quickly and effectively to security incidents.

Eradication: Removing the Threat Completely

After containing the threat, it’s time to eliminate it completely. Eradication is the process of removing malware and malicious components from infected systems.

• Why it matters: Eradication ensures that the threat is completely removed to prevent reinfection. You don’t want the malware to come back and haunt you later.
• How it works: Eradication involves identifying and removing all traces of the malware from infected systems. This may involve deleting malicious files, removing malicious registry entries, and cleaning up any other changes made by the malware.
• Tools and techniques: Specialized tools and techniques are often used for malware eradication, such as anti-malware scanners, rootkit detectors, and manual removal procedures.

Recovery: Restoring Normal Operations

With the threat eradicated, it’s time to get back to normal. Recovery is the process of restoring systems and data to a normal operational state after an incident.

• Why it matters: Recovery minimizes downtime and ensures that your business can continue operating. The faster you can recover from an incident, the less impact it will have on your bottom line.
• How it works: Recovery involves restoring systems from backups, rebuilding damaged systems, and verifying the integrity of your data. It’s like rebuilding your castle after an attack.
• Backup and Recovery: Implementing robust backup and recovery strategies is essential for successful recovery. You should have regular backups of your systems and data, and you should test your recovery procedures regularly.
• Automation: Automation can accelerate the recovery process by automating tasks such as restoring systems from backups or rebuilding damaged systems.

Post-Incident Analysis: Learning from Experience

The incident is over, but the learning never stops. Post-incident analysis involves reviewing security incidents to identify lessons learned and improve security measures.

• Why it matters: Post-incident analysis helps you prevent future incidents by identifying the root causes of past incidents. By understanding what went wrong, you can take steps to prevent similar incidents from happening again.
• How it works: A post-incident analysis report should include a timeline of events, a description of the impact, a list of lessons learned, and a set of recommendations for improvement.
• Root Cause Analysis: Root cause analysis is a key part of post-incident analysis. It involves identifying the underlying causes of the incident, rather than just focusing on the symptoms.

Vulnerability Scanning & Patch Management: Staying Ahead of Exploits

While vulnerability management is the overall strategy, vulnerability scanning and patch management are the tactical components. They are like being ahead of an issue before it causes further damage

• Why it matters: By identifying and addressing vulnerabilities promptly, you can reduce your risk of being exploited.
• How it works: Regular vulnerability scanning helps you identify weaknesses in your systems. Patch management involves applying security patches to address identified vulnerabilities.
• Automation is Key: Automated patch management tools can streamline the process and ensure that patches are applied promptly.

Capture the Flag (CTF) Competitions: Sharpening Your Skills

Time to become a cyber security ninja by going to capture the flag! Think of CTF competitions as a training ground for cybersecurity professionals.

In short, building an ATR dream team requires a mix of technical skills, problem-solving abilities, and a whole lot of dedication. With the right people in place, you’ll be well-equipped to defend against even the most sophisticated cyber threats.

Documentation and Planning: The Unsung Heroes of Your ATR Program

Think of your Active Threat Response (ATR) program as a finely tuned race car. You’ve got the engine (your technology), the driver (your security team), and the fuel (threat intelligence). But what about the race strategy and the maintenance manual? That’s where documentation and planning come in. They might not be the flashiest parts of your security program, but they’re absolutely essential for success. Without them, you’re just driving around in circles, hoping you don’t crash.

Your documentation and planning are the safety nets, the cheat sheets, and the battle plans all rolled into one. They ensure everyone knows what to do, how to do it, and why it matters, especially when the pressure is on. So, let’s dive into the two key documents that will keep your ATR program on track: the Incident Response Plan (IRP) and Playbooks/Runbooks.

Incident Response Plan (IRP): Your North Star in Times of Crisis

Imagine a security incident is a raging storm. Your IRP is your weather-beaten compass and sturdy map, guiding you through the chaos. It’s a comprehensive plan outlining how your organization will handle security incidents from start to finish. Think of it as your security team’s emergency preparedness guide, laying out roles, responsibilities, and procedures for every stage of an incident.

So, what makes up a good IRP? Here’s the roadmap:

• Incident Detection: How do you know something bad is happening? This section outlines the processes and technologies used to identify potential security incidents, from SIEM alerts to user reports.
• Analysis: Time to put on your detective hat. This is where you investigate the incident to determine its scope, impact, and severity.
• Containment: Stop the bleeding! This involves isolating the affected systems or networks to prevent the incident from spreading further. Think network segmentation or shutting down compromised servers.
• Eradication: Get rid of the bad stuff. This is where you remove the malware, fix the vulnerabilities, and generally clean up the mess left behind by the attacker.
• Recovery: Back to normal, hopefully. This involves restoring systems and data to their pre-incident state. Backups are your best friend here.
• Post-Incident Activities: What went wrong and how do we make sure it doesn’t happen again? This section focuses on reviewing the incident, identifying lessons learned, and updating security policies and procedures to prevent future incidents.

Best Practices for IRP Development and Maintenance:

• Keep it simple: Avoid jargon and overly complex language. Your IRP should be easy to understand and follow, even under pressure.
• Make it a team effort: Involve stakeholders from across the organization in the development and review process.
• Test, test, test: Regularly test your IRP through tabletop exercises or simulations to identify gaps and weaknesses.
• Keep it up-to-date: Review and update your IRP at least annually, or whenever there are significant changes to your IT environment or threat landscape.

Playbooks and Runbooks: Your Standardized Response Actions

Playbooks and runbooks are like your favorite recipes for handling specific types of security incidents. They provide step-by-step instructions for common tasks, ensuring that your team responds consistently and effectively every time. Playbooks are typically used for more complex incidents, while runbooks are used for simpler, more routine tasks.

Think of it this way: if an IRP is the overall battle plan, playbooks and runbooks are the tactical maneuvers. They allow you to automate and streamline your response efforts, reducing response times and minimizing the impact of incidents.

Example Playbook Scenarios:

• Responding to Phishing Attacks: A playbook for phishing attacks might include steps for identifying and quarantining malicious emails, disabling compromised accounts, and educating users about phishing awareness.

• Data Breaches: A playbook for data breaches might include steps for identifying the scope of the breach, notifying affected parties, and working with law enforcement.

Best Practices for Playbook/Runbook Creation:

• Document everything: Clearly document each step in the playbook or runbook, including who is responsible for each task and what tools or resources are needed.
• Automate where possible: Use SOAR platforms to automate as many tasks as possible, such as threat intelligence gathering, incident enrichment, and containment actions.
• Regularly review and update: Review and update your playbooks and runbooks regularly to ensure that they are effective and up-to-date with the latest threats.
• Make it accessible: Store your playbooks and runbooks in a central, easily accessible location, such as a shared drive or a SOAR platform.

In short, your IRP, playbooks, and runbooks are not just documents; they are living tools that will help you navigate the stormy seas of cybersecurity. Document everything, test regularly, and keep them up-to-date to ensure that your ATR program is ready for anything!

Addressing Common Attack Vectors with ATR

Active Threat Response isn’t just a fancy buzzword; it’s your shield against the digital baddies lurking in the shadows. Let’s see how ATR steps up to the plate against some of the most common cyber threats. Think of it as your cybersecurity superhero manual!

Malware Attacks (Ransomware, Viruses, Trojans): Stopping Infections in Their Tracks

• Detection & Mitigation: Imagine your systems are like a house. Malware is like a burglar trying to sneak in. ATR acts like your home security system, detecting the intruder (malware) and taking steps to lock them out and alert the authorities (your security team). This involves using real-time scanning, behavioral analysis, and signature-based detection to identify and quarantine malicious files. If a ransomware tries to hold your files hostage, ATR is there to cut the ransom note into tiny pieces!
• Prevention Strategies:
  • Endpoint Protection: This is like having a bodyguard for each of your devices, preventing malware from getting a foothold.
  • Network Segmentation: Think of this as dividing your house into rooms. If the burglar gets into the living room, they can’t access the bedrooms. This contains the spread of malware.
  • User Education: Teaching your users to spot suspicious emails and links is like teaching your family not to open the door to strangers.
• EDR and Anti-Malware Solutions: EDR (Endpoint Detection and Response) is like having CSI for your computers, providing detailed insights into what happened after an incident, while anti-malware solutions are your front-line defense, constantly scanning for and blocking known threats.

Phishing Attacks: Hook, Line, and Sinker Prevention

• Identification & Blocking: Phishing emails are like those super-convincing spam calls your grandma always falls for. ATR steps in to identify and block these sneaky attempts. Think of ATR analyzing email content, sender information, and website links to flag potential scams before they reach your users.
• User Education:
  • Security Awareness Training: Teaching users to spot red flags in emails and URLs is like giving them a “Scam Alert” radar.
  • Simulated Phishing Exercises: Sending fake phishing emails to your employees is like running fire drills. It helps them practice and stay vigilant.
• Email Security Gateways and Anti-Phishing Solutions: These act as bouncers for your inbox, checking IDs (email authenticity) and kicking out the troublemakers (phishing attempts). They scan incoming emails for malicious content, suspicious links, and unusual sender behavior.

Zero-Day Exploits: Responding to the Unknown

• Responding to the Unknown: Zero-day exploits are like a brand-new strain of super-virus that no one has seen before. ATR has to be quick and adaptable to respond. Imagine ATR using behavioral analysis and anomaly detection to identify suspicious activity even if it doesn’t match any known threat signatures.
• Proactive Mitigation:
  • Vulnerability Scanning: Regularly scanning your systems for weaknesses is like getting a check-up from the doctor.
  • Patch Management: Applying security updates is like taking your medicine to fix those weaknesses.
  • Intrusion Prevention: Setting up intrusion prevention systems (IPS) is like having an automatic security system that stops attacks in real-time.
• Threat Intelligence: Think of threat intelligence as the all-knowing detective providing clues. Threat intelligence can provide early warnings about emerging threats, even zero-day exploits, allowing you to proactively strengthen your defenses.

So, that’s active threat response CBT in a nutshell. Hopefully, this gives you a solid starting point. Now, go forth and be safe out there!
