Signature-based antivirus software is a type of security software that uses signatures to identify malware. Signatures are bits of code that are unique to a specific piece of malware. When signature-based antivirus software detects a piece of malware, it compares the signature to its database of known signatures12. If a match is found, the software can do three things to provide protection:

Alert system administrators: The software can notify the system administrators or the users about the malware detection, and provide information such as the name, type, location, and severity of the malware. This can help the administrators or the users to take appropriate actions to prevent further damage or infection3.

Quarantine the infected file: The software can isolate the infected file from the rest of the system, and prevent it from accessing or modifying any other files or processes. This can help to contain the malware and limit its impact on the system4.

Delete the infected file: The software can remove the infected file from the system, and prevent it from running or spreading. This can help to eliminate the malware and restore the system to a clean state4.

Multiple attack vectors – APTs often use various methods (phishing, malware, lateral movement) to infiltrate and maintain access to a target.

Repeated pursuit of objective – APTs are known for their persistent nature, involving continuous efforts over time to achieve their goals, such as data theft or surveillance.

SOAR stands for security orchestration, automation and response. It is a software solution that enables security teams to integrate and coordinate separate tools into streamlined threat response workflows. SOAR systems allow for accelerated incident response through the execution of standardized and automated playbooks that work upon inputs from security technology and other data flows. SOAR systems can also help ensure consistency, reduce human errors, and improve efficiency and scalability of security operations. References:

An Intrusion Prevention System (IPS) includes automated security actions, such as blocking malicious traffic, resetting connections, or alerting administrators when it detects suspicious activity, helping to stop attacks in real time.
