 | Information Gathering | Social Engineering | Gathering information from a human being in a non-technical way (e.g., using lies, tricks, bribes, or threats). |
-| Intrusion Attempts | Exploitation of Known Vulnerabilities | An attempt to compromise a system or to disrupt any service by exploiting vulnerabilities with a standardised identifier such as CVE name (e.g., using a buffer overflow, backdoor, cross site scripting) |
-| Intrusion Attempts | Login Attempts | Multiple brute-force login attempts (including guessing or cracking of passwords). This IOC refers to a resource, which has been observed to perform brute-force attacks over a given application protocol. |
-| Intrusion Attempts | New Attack Signature | An attack using an unknown exploit. |
-| Intrusions | Privileged Account Compromise | Compromise of a system where the attacker has gained administrative privileges. |
-| Intrusions | Unprivileged Account Compromise | Compromise of a system using an unprivileged (user/service) account. |
-| Intrusions | Application Compromise | Compromise of an application by exploiting (un)known software vulnerabilities, e.g., SQL injection. |
-| Intrusions | System Compromise | Compromise of a system, e.g., unauthorised logins or commands. This includes attempts to compromise honeypot systems. |

 | Availability | Distributed Denial of Service | Distributed Denial of Service attack, e.g., SYN flood or UDP-based reflection/amplification attacks. |
 | Availability | Misconfiguration | Software misconfiguration resulting in service availability issues, e.g., DNS server with outdated DNSSEC Root Zone KSK. |
-| Availability | Sabotage | Physical sabotage, e.g., cutting wires or malicious arson. |
+| Availability | Sabotage | Intentional actions maliciously threatening to, attempting to or actually damaging a system or component with the aim of disrupting the availability of a service. These can happen both at logical and physical levels, from malicious firewall rules dropping all traffic, to wire-cutting, bomb threats or arson. |
 | Availability | Outage | An outage caused, for example, by air conditioning failure or natural disaster. |
 | Information Content Security | Unauthorised Access to Information | Unauthorised access to information, e.g., by abusing stolen login credentials for a system or application, intercepting traffic or gaining access to physical documents. |
 | Information Content Security | Unauthorised Modification of Information | Unauthorised modification of information, e.g., by an attacker abusing stolen login credentials for a system or application, or ransomware encrypting data. Also includes defacements. |
