Active Cyber Defense

In today's world, everything from our emails to our bank accounts is connected online, making cybersecurity more important than ever. Imagine having a guard that doesn't just react when someone tries to break in, but actively patrols and stops any trouble before it even starts. That's the idea behind active cyber defense. Instead of waiting for hackers to attack and then fixing the damage, active defence is like having cyber guards who are always on the lookout, ready to stop attackers in their tracks.

Think about it this way: When you're playing a game, you don't just defend when the opponent attacks; you also plan your moves to outsmart them. Active cyber defence works similarly. It uses clever tricks and strategies to confuse hackers, making it hard for them to figure out how to attack or where to find valuable information. This approach is a game-changer because it's not just about building walls to keep attackers out; it's about staying one step ahead and making their attacks fail right from the start.

In the upcoming exploration, we'll take a close look at active cyber defence using important points. We'll start by understanding what active cyber defence is and how it's not the same as regular cybersecurity. Then, we'll see the good things it brings, like making things more secure. We'll also talk about the rules and what's right, and finally, we'll talk about the challenges and problems with active defence. By looking at all these things, we'll learn a lot about active cyber defence and why it matters in keeping things safe online.

What is Active Cyber Defense?

Active defence encompasses utilizing proactive strategies to outwit or impede hackers, complicating the execution of cyberattacks. Active defence revolves around employing deception technology to swiftly detect attackers in the early stages of an attack cycle. This involves tactics like digital baiting and creating deceptive device decoys that obscure the attack landscape and deceive assailants. This diversionary approach consumes hackers' time and computational resources while yielding crucial insights into ongoing cyber threats. While active defence lends support to offensive manoeuvres and may involve retaliatory measures against attackers, such actions are typically the prerogative of law enforcement agencies. These entities possess the necessary authority and resources to execute appropriate responses.

Does active cyber defence differ from traditional cyber security approaches?

Active defence is different from regular cybersecurity because it's more active and dynamic. Instead of just waiting and reacting, active defence actively looks for trouble and stops it early. Regular methods focus on preventing known problems, like using firewalls and antivirus software. But these methods might miss new and tricky attacks.

Active defence is like going out to catch bad guys before they can do much harm. It uses tricks, like pretending to be a target or distracting attackers. This confuses them and helps us learn about their plans. By fooling attackers into showing their tricks or wasting their time, active defence makes it harder for them to succeed.

While regular cybersecurity tools are important, active defence adds an extra layer of protection. It actively searches for threats and stops them from causing trouble. This is because just waiting for attacks to happen isn't good enough anymore. Active defence takes cybersecurity a step further by being proactive and stopping problems before they get worse.

Techniques of Active Cyber Defense

The two most common techniques and known techniques are digital baiting and the use of decoy devices.  Digital baiting involves placing tempting but ultimately unimportant digital clues that trick hackers into showing their methods and intentions. This helps in two ways: gaining useful information about how attackers work and keeping them busy with something that won't lead to success. Additionally, using decoy devices is a smart method to confuse attackers. These devices copy real assets, tricking hackers into going after things that aren't important. This not only makes attackers waste their time and effort but also lets defenders study how they work, helping to plan better ways to protect against them in the future.

Are there any legal or ethical considerations with active defence?

In the world of cybersecurity, using active defence strategies brings up important legal and ethical questions that organizations must think about carefully. When we talk about active defence, we mean taking action to fight against hackers. But these actions can create tricky situations.

Legally, fighting back against hackers might get you in trouble. Some places consider it as taking the law into your own hands, and that can lead to legal problems. Also, because cyberattacks happen from all over the world, attacking back might break international laws and agreements.

Thinking ethically, there's a moral side to it too. Fighting back might make it seem like both sides are the same, blurring the line between good guys and bad guys. Also, hitting back could cause more problems than solutions. And when you use resources to attack, you might end up ignoring the bigger picture of keeping things safe overall.

It's not easy to know who's behind an attack, and that makes the situation even trickier. If you hit the wrong people, it's not fair and can cause a lot of problems. To handle this, organizations need to carefully study the laws in their area and think about what's right. Getting advice from experts and following the rules is the way to use active defence legally and ethically.

Challenges associated with active cyber defence

Using active defence in cybersecurity has its own set of problems. Even though it's a good way to fight cyber threats, there are things to watch out for.

1. Legal and Ethical Issues: Active defence might break laws or cause ethical problems. Fighting back could get you in trouble. Finding a balance between doing the right thing and following the rules is important.

2. Figuring Out Who's Behind Attacks: Knowing who's attacking you can be hard. Getting it wrong might mean fighting the wrong people, which can lead to more problems.

3. Making Things Worse: Sometimes, trying to fight back can make things worse. It can make attackers angrier and cause more attacks.

4. Using Resources Wisely: When you spend time and effort fighting back, you might forget about keeping everything else safe from attacks.

5. Accidentally Hitting Others: Sometimes, trying to fight attackers might accidentally hurt other people or systems that aren't involved.

6. Smart Attackers: Attackers are always learning and changing their ways. So, active defence tactics need to stay up-to-date.

To handle these problems, it's important to think about the good and bad sides of active defence. Getting advice from experts and making sure you're doing the right thing legally and morally is key.

Active Defense Cyber Cycle 

The Active Cyber Defense Cycle is a smart plan to make sure important things like oil and gas systems are safe from computer attacks. It has four parts that work together to keep things secure:

1. Finding Things and Watching the Network: First, we need to know what's in the network and how it works. This helps us see if anything strange is happening that might be a problem.

2. Dealing with Problems: If we find something wrong, we have a plan ready to fix it. We work fast to gather proof, figure out what's wrong, and stop the problem from spreading.

3. Learning About the Bad Things: After stopping a problem, we learn more about it. We study it to understand how it works and how we can protect against it in the future.

4. Using What We Learned: The things we learn are important. We use this knowledge to make our defence even stronger, so we're ready for similar problems in the future.

This cycle helps keep important systems safe by being active and staying prepared for any issues.

In conclusion, active cyber defence is a proactive strategy designed to stay one step ahead of cyber threats. By utilizing clever tactics, it confuses hackers and thwarts potential attacks. Although it offers significant benefits, it also sparks legal and ethical considerations. Despite the challenges, active defence remains a valuable method for safeguarding digital systems. The Active Cyber Defense Cycle strengthens this approach by ensuring constant vigilance and preparedness against potential threats. Ultimately, active cyber defence plays a crucial role in upholding online safety within our interconnected world.
