Security professionals have long known that the dark web is a hotbed of criminal activity. With the increasing popularity of ransomware and other malicious threats, incorporating dark web intelligence into your security information and event management (SIEM) system has become more critical than ever. This article will explain why dark web threat intelligence is vital to any effective SIEM strategy.
What is the Dark Web?
The dark web is a part of the internet that can only be accessed using special software, such as the Tor browser. It is a haven for criminal activity, including selling illegal drugs, weapons, and stolen data. The dark web is also home to various malicious actors, including hackers, scammers, and cybercriminals.
The surface web is 4% of the internet, while the deep web is 90% of the internet. The dark web makes up only 6%, but it is the most dangerous part.
Surface Web-
The surface web is what we can access through search engines like Google, Microsoft Bing, and Yahoo. It’s also sometimes called the clear web or visible web.
Deep Web-
The deep web is the part of the internet that isn’t indexed by search engines. It includes anything behind a paywall or login, including email and social media accounts.
Dark Web –
The dark web is a small part of the deep web that can’t be accessed without special software, like the Tor browser. It’s used for illegal activity, like buying drugs or stolen credit card numbers.
The first thing to understand about the dark web is that it is anonymous. Users can not be tracked or identified by their IP address. This anonymity makes the dark web a popular destination for criminals and those who wish to remain hidden from the authorities.
The second thing to understand about the dark web is that it is encrypted. This means that data exchanged between users is highly secure and difficult to intercept by third parties. The combination of anonymity and encryption makes the dark web a haven for criminal activity.
The Need for Dark Web Threat Intelligence Feeds and Why It Matters
So, why is dark web threat intelligence a key component of your SIEM system? The answer is simple: many cyber threats originate on the dark web. By monitoring the dark web, you can gain early warning of new attacks and vulnerabilities, as well as identify the motives and methods of criminals.
To effectively monitor the dark web, you need a tool to collect and analyze data from various sources. This is where dark web intelligence feeds come in. Dark web intelligence feeds help security professionals track and investigate dark web activity.
Each threat intelligent feed collects data from various sources, including forums, chat rooms, and marketplaces. This data is then analyzed and distilled into actionable intelligence that can be used to help protect your organization from dark web threats. Dark Web threat intelligence is data collected from the dark web – the parts of the internet that are not easily accessible or indexed by traditional search engines. This data can provide insights into cybercriminal activity and trends, which can help organizations better understand the cyber risk landscape and take steps to protect themselves.
The emerging Threat (ET) intelligence feed is essential to your SIEM because it can provide early warning of new attacks. Emerging Threats collects data from various sources and analyzes it to identify new threats. This information can then be used to help protect your organization from these threats.
To get started with the dark web threat intelligence feed, you need to find a reputable provider that offers ET intelligence feeds. Once you have found a provider, you need to subscribe to their feed and configure it in your SIEM system. After that, you will start receiving data from the provider that you can use to improve your SIEM system.
There are many benefits to using dark web intelligence feeds, including:
1) Early warning of new threats: By using a dark web intelligence feed, you can gain early warning of new attacks and vulnerabilities. This information can then be used to help protect your organization from these threats.
2) Improved detection and response: Dark web intelligence data can be used to fine-tune your SIEM system and ensure it is as effective as possible at detecting and responding to threats.
3) a Better understanding of the threat landscape: By monitoring the dark web, you can gain insights into the latest threats, vulnerabilities, and trends. This information can then be used to understand the risk landscape better and take steps to protect your organization.
4) Increased efficiency: Using a dark web intelligence feed can help you automate collecting and analyzing data. This can save you time and resources better spent on other tasks.
5) Cost savings: By using dark web intelligence, you can reduce the need for other security tools and services. This can lead to cost savings for your organization.
Dark web intelligence is a valuable tool that can help you to improve your SIEM system and protect your organization from threats. If you are not already using this type of data, then you should consider doing so.
Information that threat analyst finds on the dark web is:
1) New attacks and vulnerabilities: By monitoring the dark web, analysts can warn early about new attacks and vulnerabilities. This information can then be used to help protect organizations from these threats.
2) Motives and methods of criminals: The dark web is a popular destination for criminals because it offers anonymity and encryption. By understanding the motives and methods of criminals, analysts can better understand the risks they pose to organizations.
3) Cybercriminal trends: Dark web intelligence feeds can help analysts to track and investigate cybercriminal activity. This information can then be used to understand the risk landscape better and take steps to protect organizations from these threats.
4) Analysts might find another type of information on the dark web: exposed credentials. Attackers can use these to gain access to systems or data. Often, these credentials are stolen in data breaches and then sold on the dark web.
5) Data access is another type of information found on the dark web. Attackers can use this to gain access to sensitive data. Often, this data is stolen in data breaches and then sold on the dark web.
Analysts can use all this information to understand their organization’s threats better and take steps to protect themselves.
Conclusion:
Dark web threat intelligence is a valuable resource to help organizations protect their data and systems. By monitoring the dark web, businesses can gain early warning of potential attacks, identify compromised or stolen credentials, and find new vulnerabilities in their networks before they are exploited. -A SIEM (security information and event management) system is essential for tracking all activity across an organization’s IT infrastructure.
A SIEM collects data from various sources, including firewalls, routers, switches, endpoints, and the Dark Web, and analyzes it to identify malicious or unauthorized activity. -When used together, dark web threat intelligence and SIEM provide comprehensive security coverage for an organization’s entire network.
