What is Behavior monitoring?

Behavior Monitoring in Antivirus: Detecting and Preventing Malware Attacks

Behavior monitoring is a key aspect of cybersecurity that plays a vital role in preventing and responding to potential security threats. It refers to the process of observing, tracking, and analyzing the activities or behaviors of computer systems, network elements, or users to identify any abnormal or suspicious activities. It is featured extensively in today's advanced cyberdefense mechanisms such as antivirus software, threat detection systems, and intrusion-detection/prevention systems.

Behavior monitoring is essentially a proactive approach that aids organizations to detect and handle threats which frequently evade traditional security barriers. By focusing on the behavior of a system or a user instead of the characteristics of a threat, it can identify harmful actions even if the specific malware or intrusion method is new or previously unknown.

In practice, behavior monitoring is accomplished through advanced technologies and approaches such as data analytics, artificial intelligence (AI), and machine learning algorithms. These technologies can identify specific patterns in an extensive range of behaviors and analyze the collected data to detect threats based on unusual or uncharacteristic behaviors.

When it comes to antivirus software, behavior monitoring is how these programs have evolved to combat an ever-evolving landscape of threats. In the early days, antivirus software chiefly relied on definition databases. These databases contain known threats' specific traits or definitions, and the antivirus software will raise an alert or execute corrective action if it encounters anything that matches these definitions.

This type of antivirus is painfully inadequate for today's high-tech cyberthreats because criminals continuously develop new viruses. Though companies daily update virus definitions, they still prove helpless against threats not yet defined.

To counter this, antivirus software now features behavior monitoring. This approach shifts focus from identifying known threats to identifying suspicious system behaviors. Therefore, even if a threat isn't defined in an antivirus's database, if it behaves similarly to known threats (by altering files, changing system configurations, etc.), it's recognized as a possible risk, enabling proactive measures.

Behavior monitoring doesn't end at the detection of possible threats. After identifying suspicious behavior, monitoring systems undertake corrective steps for damage control. Steps may include isolating the device from the network to prevent the spread or automatically reversing the suspicious activity on the system. At the same time, they alert the network administrators about the anomaly, enabling quick decision-making.

Predictive capability is another critical aspect of behavior monitoring. It excels in predicting possible threats based on the collection and analysis of historical data. AI-enhanced tools specifically analyze past incidents and learn from those events. It helps them identify potential threats or vulnerabilities and predict future attacks. It is particularly useful in countering distributed denial-of-service (DDoS) attacks, data breaches, and issues related to ransomware.

Behavior monitoring is a highly effective and crucial aspect of cybersecurity especially in terms of strengthened antivirus programs. It works by focusing on patterns of behavior rather than relying solely on identifying harmful entities based on pre-defined characteristics. This not only allows the identification of new, previously unknown threats but also provides quick and efficient response mechanisms. Predictive capability for proactive cyber defense is another of its key features. The combination of these features promotes preventative steps before disasters strike, diminished impact of attacks, reduced system downtimes and a more secure cyber environment.
