Behavior-Based Security

What is Behavior-Based Security?

Behavior-based security is a cutting-edge approach to cybersecurity that seeks to identify and protect against malicious activity by monitoring user behavior. It is a proactive approach that monitors all relevant activity so that any deviations from normal behavior patterns can be quickly identified and addressed. This type of security is becoming increasingly important as the digital footprint of organizations expands and centralized cybersecurity becomes more difficult to manage. According to the Symantec cybercrime report, cyber attacks are becoming more attractive and potentially more disastrous as our dependence on information technology increases.

McKinsey examines three of the latest cybersecurity trends, including behavior-based security, and their implications for organizations facing new and emerging cyber risks. As we look ahead into 2023, experts predict that attackers will shift their focus from large enterprises to smaller businesses with fewer resources for protection. The Howlers have identified eight key security trends for 2022 which include artificial intelligence (AI) driven threat detection, cloud-native application protection, zero trust architecture implementation, increased use of biometrics authentication methods such as facial recognition or fingerprint scanning, improved endpoint detection capabilities through machine learning algorithms, increased use of encryption technologies such as quantum cryptography or homomorphic encryption systems , greater emphasis on data privacy regulations such as GDPR or CCPA compliance ,and finally an increase in automated incident response solutions . All these trends point towards a future where behavior-based security will play an even larger role in protecting businesses from malicious actors online.

What is Behavior-Based Security?

Behavior-based security is a type of security technology that monitors user behavior and identifies any malicious activity. It is based on the idea that if a user is behaving in a way that is suspicious or out of the ordinary, the system can detect it and take action. For example, if a user is trying to access a system that they don’t have permission to access, the system can detect this and alert the appropriate authorities. This type of NIDS (Network Intrusion Detection System) uses behavioral analysis to determine whether any suspicious activity has occurred. If the behavior being analyzed meets certain criteria, then an alert will be triggered.

Behavioral analytics utilizes big data analytics and artificial intelligence on user behavioral data to identify patterns, trends, anomalies, or other indicators of malicious activity. This allows for more accurate detection than signature-based intrusion detection systems which rely solely on identifying known attack signatures in order to trigger an alert. Anomaly-based IDS solutions are also able to detect unknown threats as they are not limited by pre-defined attack signatures like signature-based systems are.

An intrusion detection system (IDS) monitors network traffic for suspicious activity and alerts when such activity is discovered. The IDS (Intrusion Detection System) was one of the first tools used for this purpose and it continues to be used today as part of many organizations’ security strategies due its ability to monitor vulnerabilities in a system and analyze network traffic for signs of malicious intent or unauthorized access attempts from outside sources such as hackers or malware programs attempting unauthorized access into networks or systems with sensitive information stored within them.

For MSPs (Managed Service Providers), understanding these key differences between signature-based and anomaly-based intrusion detection systems can help them better protect their clients’ networks from potential threats while also providing more comprehensive coverage against unknown attacks which may not have been identified yet by traditional signature-based solutions alone. Behavior based security provides an additional layer of protection against these types of threats by monitoring user behavior in order to identify any unusual activities which could indicate malicious intent before damage occurs – allowing MSPs greater peace of mind when it comes protecting their clients’ networks from potential cyberattacks

What Are the Benefits of Behavior-Based Security?

Behavior-based security is a powerful tool for protecting against malicious activity. It requires users to actively engage in malicious behavior, making it difficult for attackers to remain undetected or change their identity. Additionally, since it is an automated system, it is much more efficient than manual security measures. This makes it harder for attackers to bypass and allows organizations to detect threats quickly and accurately.

Intrusion detection systems are used in conjunction with behavior-based security measures to monitor events occurring in a computer system or network and analyze them for signs of possible incidents. This helps organizations identify potential threats before they can cause damage or steal data. Additionally, the use of antivirus software helps protect computers against malware and cybercriminals by seeking to block or remove malware as quickly as possible.

The combination of these two methods provides an effective defense against online threats such as malware that grants network access and allows for remote, stealth operations. By combining traditional security measures with behavior-based security, organizations can better protect themselves from malicious actors who may be attempting to gain access without being detected or changing their identity. Furthermore, this type of defense is more efficient than manual methods since it relies on automated systems that can detect threats quickly and accurately without requiring human intervention every time a threat arises.

How Does Behavior-Based Security Work?

Behavior-based security is a proactive approach to security that monitors user activity and compares it to predetermined criteria. This allows the system to detect any suspicious or unusual behavior, such as access levels, login attempts, and system usage. If the behavior matches any of these criteria, the system can take action such as alerting security personnel or blocking the user from accessing the system.

User access security is another important aspect of behavior-based security. It refers to procedures by which authorized users can access a computer system while unauthorized users are kept out. The Federal Highway Administration Information Systems – UPACS Rules of Behavior page requires users to agree to Terms and Conditions of Use and Rules before they can gain access.

The National Initiative for Cybersecurity Careers and Studies (NICCS) glossary contains key cybersecurity terms that enable clear communication between stakeholders in order for them to have a common understanding of cybersecurity definitions. It is important for organizations implementing information security measures understand the difference between detection vs protection technologies; some are designed simply “detect” suspicious activity while others protect raw data from internet-based threats. Behavior-based security works by monitoring user activity in order to identify any deviations from normal behavior patterns so that appropriate action can be taken if necessary.

What Are the Potential Drawbacks of Behavior-Based Security?

Behavior-based security is a powerful tool for detecting malicious activity, but it also has some potential drawbacks. False positives and false negatives can occur when the system incorrectly identifies benign activity as malicious or fails to identify malicious activity. This can lead to legitimate activities being blocked, which can be disruptive and costly. Additionally, the system requires significant monitoring and upkeep in order to remain effective, making it expensive to implement and maintain. Finally, since the system is automated, it is vulnerable to attack such as denial of service attacks.

User access security refers to the procedures by which authorized users are granted access while unauthorized users are kept out of a computer system. Cyber-attacks have become increasingly sophisticated over time, making it more difficult for behavior-based security systems to accurately detect intrusions. As such, false positives or false negatives may occur when normal activities are mistakenly identified as an attack or when malicious activities go undetected respectively. It is better for an Intrusion Prevention System (IPS) to be oversensitive in order detect abnormal behaviors that generate false positives than undersensitive which generates false negatives; however this could lead to legitimate activities being blocked due disruption and costliness associated with this mistake. Furthermore, since behavior-based security systems are automated they may be vulnerable attacks such as denial of service attacks that could render them ineffective if not properly monitored and maintained on a regular basis – adding additional costs associated with implementation and upkeep of these systems.


In conclusion, behavior-based security is a powerful tool for identifying and protecting against malicious activity. It is an automated system that monitors user activity and looks for any suspicious or unusual behavior, and can take action if necessary. This proactive approach to security involves monitoring all relevant activity so that deviations from normal behavior patterns can be identified. A Network Intrusion Prevention System (NIPS) provides broad-based protection of an entire network from anomalous or suspicious behavior. Anomaly-based IDS solutions go beyond identifying particular attack signatures to detect and analyze malicious or unusual activities. Furthermore, insider threats are security vulnerabilities or attacks that originate from individuals with authorized access to company networks, applications or data which can be monitored by IDS products searching for suspicious behavior or signs of a potential compromise by analyzing the packets that move across the network and the associated logs. Compliance Management and Reporting also helps organizations identify insider threats in order to protect their systems from malicious actors. Behavior-based security has some potential drawbacks such as false positives and vulnerability to attack but it is still a powerful tool for ensuring the security of systems and networks when used correctly.
