What is Adversary Simulation with Caldera?

Published

February 29, 2024

In the first of these three use cases, Caldera seeks to test the detection capabilities of several tools of the same type (for example, multiple EDRs together). This approach allows users to compare and select the tool that best suits their needs, based on context, expectations, and Caldera’s detection capabilities. Additionally, evaluating the investigative possibilities among different tools is intriguing because it provides valuable insights into their effectiveness.

Today, attacks are increasingly complex and spread out over time. This is why experts are now talking about Advanced Persistent Threat (APT). In response, detection mechanisms have also evolved, with the advent of Endpoint Detection & Response (EDR) technologies, which aggregate and correlate single events to help detect weak attack signals. These EDRs, among other technologies, are generally operated within a Security Operation Center (SOC). So how do we ensure that these detection mechanisms are configured correctly, and how effective are they?

What is the role of adversary simulation?

Adversary Simulation, often referred to as Red Team Testing, is a cybersecurity technique that involves simulating real-world cyberattacks to assess an organization’s security posture. In practice, this comes in the form of servers and/or agents, which simulate attacks or exploits of vulnerabilities, in a more or less complex and procedural manner.

In order to categorize and reference attacks correctly, different security frameworks are used, such as the Cyber Kill Chain or the MITER ATT&CK matrix. The Cyber Kill Chain offers, for example, a list of 227 attack techniques divided into 14 tactics, and is widely used to simulate the stages of a complex attack.

What is Caldera?

The non-profit organization “ MITRE ” , which is at the origin of the “ ATT&CK ” framework mentioned above, has also developed an Open Source adversary simulation tool: Caldera, available on GitHub.

Its operation is rather simple. Only install it on a dedicated server, then deploy an agent that functions identically to a Beacon on client machines. The server can then act in a manner identical to a “ Command and Control ” (C2), by giving directives to the agents to carry out different attacks or data exploitations.

What makes this tool interesting is, beyond giving instructions to a live agent, that it allows you to develop or replay complete attack scenarios. In particular those carried out by APT groups or by companies having carried out an intrusion test operation on the IS.

Caldera natively offers a number of commands and tools. The latter, called “ Ability ”, allows for example to do enumeration, download payloads or malicious tools – such as “ Mimikatz ”, but above all to execute them. However, some of them are templates, and therefore require modification. Finally, it is also possible to create your own Ability based on “ in-house ” scripts , for greater flexibility. An interesting capability of Caldera is its ability to obfuscate, which enables it to hide malicious commands by interpreting them as base64, for example.

When and why to use it?

Caldera can test different detection tools and means, replay the different stages of an intrusion test or a security audit, or even prepare a SOC.

Tool Detection Capability Testing

Scenario Reproduction for Attack Testing

For the second case, the idea is to faithfully reproduce the attack scenario used by the company that carried out the intrusion test. This action aims to verify that the scenario fails, once the auditors have effectively implemented the recommendations.

Integration with SOC for Enhanced Detection

Finally, the last use case is where Caldera receives a SOC. Indeed, the SOC collects data from all deployed security tools and adds a part of event correlation with a SIEM ( Security Information and Event Management ). This makes it possible to refine detections, based on all the data sources collected. The use of an adversary simulator can therefore contribute to the recipe of a SOC, and verify the effectiveness of its detections in the face of complex attack scenarios.

In a context where the concept of Purple Team is increasingly important, adversary simulation is undoubtedly the key element of its implementation, in order to guarantee continuous improvement of detection tools and IS configurations. It allows you to test all the processes put in place by the SOC to ensure that they work optimally. However, its use in no way replaces a real Red Team operation , it is only a complement to it. The combination of these two factors will contribute to a comprehensive and viable security strategy.

Conclusion:

In conclusion, Caldera presents a vital tool for modern cybersecurity, enabling organizations to proactively assess and enhance their defense mechanisms. By simulating attacks and exploits, Caldera empowers companies to validate detection solutions, recreate real-world scenarios, and bolster Security Operation Center readiness. Its flexibility and open-source nature make it a valuable asset in the ongoing battle against advanced cyber threats. Embracing adversary simulation tools like Caldera is essential for organizations striving to maintain resilience in the face of evolving security challenges.

Everything you need to know about portable solar panels

Published

3 months ago

April 20, 2024

Sidra Yousfazai

Portable solar panels offer new freedom. They allow you to have a power supply everywhere. Space-saving and very efficient, they increase your autonomy on vacation and during all your travels.

Table of Contents

What are portable solar panels?

Portable solar panels are miniature photovoltaic panels that convert the sun’s energy into electricity. They can power a charger or a portable battery. Lightweight and designed to be used everywhere, they allow you to charge all electronic devices : smartphone, camera, tablet, GPS, laptop, camera. With a panel measuring 32 x 17 cm and only 3 mm thick, you will be able to supply electricity to all your small devices such as smartphones or sports cameras. A 6W panel can produce 1500 to 3300 mAh per day.

Portable solar panels are suitable for all outdoor leisure activities: skiing, hiking or the beach. If you travel by motorhome, by boat or if you go trekking, you will considerably increase your energy autonomy.

The panel provides electricity directly or stores it in a miniature battery . This is external for high-power panels or integrated inside a module for extra-flat flexible panels . It is then possible to use the stored energy on cloudy days or even at night.

Portable solar panels offer efficiencies of 10% to 23%. Charging times are almost identical to those of the original chargers. If the panel is used live, one hour of charging provides 10 minutes of communication with a mobile phone.

Large models can be folded to save space. An unfolded panel of 47 x 21 cm takes up only 21 x 13.5 cm when folded. Reinforced eyelets make attachment easier. The weight of solar panels varies from 150 g to 2.5 kg. Smaller models have a USB connection.

More powerful panels offer a 12V or 18V output. High-end models are particularly efficient because they have most often been designed for military use. They are therefore suitable for intensive use, even in extreme conditions.

Two main types of portable solar panels

There are two types of portable solar panels:

single-layer panels:

There are two subtypes; monocrystalline silicon models and so-called amorphous models. Monocrystalline panels are the least expensive. Amorphous silicon panels are lighter and stronger but cost 20 to 30% more. The efficiency of amorphous silicon panels is lower (around 10%) but they can be used over a wider time range.

thin-layer flexible panels:

These so-called second or third generation panels are made up of several layers. They have excellent performance and remain effective even when the light is reduced. Several materials can be used for their design:

amorphous silicon;
and CIGS ;
with CdTe;
organic polymers.

Flexible solar panels are thin and light. They can fit anywhere. The multifunction panels allow you to recharge external batteries but also a laptop.

Main advantages and disadvantages

Solar chargers are very useful for all outdoor trips. Batteries have a limited useful life, so it can be very useful to have a backup electrical source when you spend several hours or several days without access to a fixed electrical installation.

The main advantages of portable solar panels are:

their practicality : they are light, compact;
their effectiveness : they are resistant and waterproof
and their hardiness : they can withstand temperatures from -40° to +60°.

Besides their many advantages, portable solar panels do have some disadvantages:

Sometimes limited compatibility: you must ensure before purchasing that the portable panel is compatible with the devices to be recharged.

As mobile devices need a constant power supply to properly recharge their battery, it is advisable to use a buffer battery when the weather is cloudy,

Some high-power batteries require the use of a voltage regulator or solar booster to regulate the charge and protect the system.

Mobile solar panels are more expensive per 100 watt peak than regular solar panels.

For these reasons, it is recommended that you consider mobile solar panels if you want to use them in a place where there is no electricity grid. In that case, it is an excellent sustainable alternative to provide yourself with electricity. Do you want to use solar power at home? Then traditional solar panels are more efficient.

FAQs:

How does a portable solar battery work?

Solar panels generate direct electric current (DC), which is subsequently directed to the solar battery. The battery consists of reversible electrochemical accumulators, making it rechargeable. Subsequently, the energy extracted from the battery passes through the inverter.

What are the three types of solar panels?

There are three distinct types of solar panels, each with its own unique characteristics and energy production methods. These include thermal panels, photovoltaic panels, and hybrid models.
