SOAR tools ingest aggregated alerts from detection sources (such as SIEMs, network security tools, and mailboxes) before executing automatable, process-driven playbooks to enrich and respond to these alerts.

IDSs and IPSs also can be classified as knowledge-based (or signature-based) or behavior-based (or statistical anomaly-based) systems:

● A knowledge-based system uses a database of known vulnerabilities and attack profiles

to identify intrusion attempts. These types of systems have lower false-alarm rates than

behavior-based systems but must be continually updated with new attack signatures to

be effective.

● A behavior-based system uses a baseline of normal network activity to identify unusual

patterns or levels of network activity that may be indicative of an intrusion attempt.

These types of systems are more adaptive than knowledge-based systems and therefore

may be more effective in detecting previously unknown vulnerabilities and attacks, but they have a much higher false-positive rate than knowledge-based systems

Selective network security virtualization: Intra-host communications and live migrations are architected at this phase. All intra-host communication paths are strictly controlled to ensure that traffic between VMs at different trust levels is intermediated either by an on-box, virtual security appliance or by an off-box, physical security appliance.

Pharming is an attack that redirects traffic from a legitimate website to a malicious fake website, typically by corrupting the DNS system or modifying host files, with the intent of stealing user credentials or sensitive data.
