Report incidents

What is an incident?

A good but fairly general definition of an incident is the act of violating an explicit or implied security policy. Unfortunately, this definition relies on the existence of a security policy that, while generally understood, varies among organizations.

In general, types of activity that are commonly recognized as being in violation of a typical security policy include but are not limited to:

  • attempts (either failed or successful) to gain unauthorized access to a system or its data, including Personally Identifiable Information (PII) related incidents. For more information on the privacy guidelines for incident handling, refer to the DHS Privacy Incident Handling Guidance (PIHG).
  • unwanted disruption or denial of service
  • the unauthorized use of a system for processing or storing data
  • changes to system hardware, firmware, or software characteristics without the owner's knowledge, instruction, or consent

Report phishing

What is phishing?

Phishing is an attempt by an individual or group to solicit personal information from unsuspecting users by employing social engineering techniques. Phishing emails are crafted to appear as if they have been sent from a legitimate organization or known individual. These emails often attempt to entice users to click on a link that will take the user to a fraudulent website that appears legitimate. The user then may be asked to provide personal information, such as account usernames and passwords, that can further expose them to future compromises. Additionally, these fraudulent websites may contain malicious code.

Report malware

What is malware?

Malware is a general term used to refer to a variety of forms of hostile or intrusive software. The term applies to both true (malicious) malware and unintentionally harmful software.
