As cyber attacks become more commonplace, the ability to identify, monitor, and block threats is critical. Last year, nearly three-quarters of all businesses faced a threat to their security, with each incident potentially halting operations for days or even weeks.
Read on to discover what threat monitoring is, why it’s crucial, the types of threats you need to watch out for, and how tools like ProLion’s DataDefense can help keep your data secure.
What is Threat Monitoring?
Threat monitoring is the continuous process of observing, analyzing, and evaluating an organization’s IT environment for potential security risks and malicious activities. This proactive approach involves using various tools and technologies to collect and analyze data from networks, systems, and applications in real-time, allowing organizations to detect and respond to potential threats before they can cause significant damage.
Why Is Threat Monitoring Important?
Threat monitoring is a vital component of an organization’s cybersecurity strategy. Here’s why:
Minimize Damage
Detecting threats early significantly reduces the potential impact of cyber-attacks. The sooner you realize what’s going on, the less time cybercriminals have to lurk in your network, inflicting substantial damage.
That’s why breaches disclosed by attackers cost businesses nearly $1 million more on average than those detected internally by the organization’s monitoring systems.
Align with Regulatory Compliance
Many industries are subject to strict regulatory requirements that mandate the monitoring of sensitive data. Threat monitoring tools help ensure compliance by providing logs and audit trails of data access and system activity.
This is essential for meeting legal standards and for protecting against potential litigation or penalties that could arise from failing to safeguard consumer and business data.
Enhance Cyber Resilience
Threat monitoring is crucial for building cyber resilience. This resilience allows organizations to maintain their operations even when faced with cyber disruptions. By continuously monitoring for threats, organizations can adapt to new threats, recover quickly from disruptions, and minimize operational downtimes, thereby maintaining a strong defense against the evolving landscape of cyber threats.
Types of Threats
There are many different types of cyber threats, and criminals invent new ones all the time. Here’s a breakdown of common cyber threats:
- Ransomware: This malware steals and encrypts data, then demands a ransom for its decryption. Even if you pay the ransom, there is no guarantee that you will get your data back.
- Phishing and Spam: Phishing involves fraudulent attempts to obtain sensitive information by pretending to be a legitimate entity, like a well-known business or services provider. For example, a hacker might send a spam email to your employee to obtain their credentials and use that information to gain access to your system.
- Viruses and Worms: These are malicious programs that can replicate themselves and spread to other computers. Viruses typically attach themselves to executable files and compromise system integrity, while worms can propagate without human interaction.
- Spyware: This software is designed to gather information about a person or organization without their knowledge, often leading to privacy breaches and significant security risks.
- Distributed Denial of Service (DDoS) Attacks: These attacks flood systems, servers, or networks with traffic to overwhelm resources and render them unavailable to intended users.
- Supply Chain Attacks: Third-party attacks occur when attackers infiltrate a system through an outside partner or provider with access to systems and data. This type of attack can compromise the security of multiple organizations through a single breach.
- Doxware: A variant of ransomware, doxware threatens to publish sensitive data online unless a ransom is paid, targeting both individual privacy and corporate data security.
This list isn’t comprehensive. But recognizing these threats is a key step toward safeguarding your organization’s assets and keeping your systems secure.
Threat Monitoring Techniques
Considering the vast amount of threats out there, effective monitoring is essential. ProLion’s DataDefense employs both signature-based and behavior-based detection methods to provide comprehensive protection against ransomware. Here’s how each method works:
Signature-Based Detection
This method relies on pre-defined signatures of known ransomware to identify threats. For instance, if your file system shows files renamed to “financial_report.docx.locky” or “financial_report.docx.wannacry,” it indicates an infection by Locky or Wannacry ransomware.
ProLion maintains a continuously updated database of such signatures, enabling DataDefense to quickly identify and alert you to these known threats.
Behavior-Based Detection
Moving beyond known signatures, behavior-based detection uses algorithms to look at the actions and patterns of files and applications within your system. This method is crucial for identifying new or unknown ransomware strains. It monitors:
- File System Changes: Observes excessive file modifications, typical of encryption attempts
- Network Traffic Anomalies: Detects unusual data transmissions that could indicate data exfiltration or communication with a command and control center
- Suspicious API Calls: Some advanced systems can identify API usage patterns that may signify malicious intentions, such as sandbox detection or privilege escalation
ProLion DataDefense uses behavior-based monitoring that focuses on these first two elements— file system behavior and network patterns—to catch and mitigate ransomware activities. DataDefense’s real-time monitoring capabilities provide immediate alerts and response options, ensuring that even the most sophisticated attacks can be blocked before they inflict damage.
Monitor Threats with ProLion’s DataDefense
ProLion’s DataDefense integrates two advanced threat monitoring methodologies (signature and behavior-based detection) to form a robust defense against cyberattacks. This creates a layered security approach that identifies and blocks both known and new threats.
The result is a highly effective monitoring system that enhances your organization’s resilience and enables you to proactively manage risks and keep your data secure.
