Incidents
The Alert Logic console displays information about incidents, how to use that information to manage and close incidents, and how to secure your environments. An incident includes one or more suspicious events that require attention to maintain your security posture, achieve regulatory compliance, or both. Alert Logic generates incidents from multiple detection sources, and then organizes the incidents by threat level and classification type.
You can check the operational status of the Alert Logic intrusion detection services in the Service Status page in the Alert Logic console. Alert Logic recommends that you subscribe to the Service Status page and all your Alert Logic components, including Network IDS.
View incidents
The Incidents page in the Alert Logic console provides you with the information you need to analyze and address incidents in your environment.
The list on the Incidents page displays all the open, snoozed, or closed incidents in your account environment, as well as the account, deployment, date and time, the IP address of the attacker, and the target appliance name.

Advanced incident search
The advanced search feature allows you to create complex queries that can combine with selected filters to further refine your incident search results. To access the advanced search feature, click advanced search under the search bar.
In the advanced search field, type a query statement using available fields and operators. If needed, you can use subsequent search fields to add OR statements and create a search that tests for multiple conditions. As you type a search statement, a warning icon () appears to the left of the search field until the query contains valid syntax. You cannot submit a search with invalid syntax.
A common query you can perform with the advanced incident search is:
The query below searches for brute force incidents.
Classification="brute-force"
For a complete list of fields and additional sample search statements, see Perform Advanced Searches.
Search by date and time range
The date range drop-down menu allows you to display incidents that occurred during a selected date range and within a time range for the selected dates. Select from the following to display incidents that occurred within the specified date and time range:
- This Month— Displays a calendar of the current month with all days highlighted.
- Today— Displays a calendar with the current day highlighted.
- This Week— Displays a calendar with the current week highlighted.
- All— Displays a calendar, on which you can click to select days, or a date range, for which you want to see incidents.
Each selection allows you to specify a time range to further narrow the search results.
About threat levels
Incident threat levels convey the severity of each incident raised for protected assets, which allows you to assess and prioritize the actions to take toward threat remediation. Alert Logic categorizes incidents with the following icons and colors:
- Critical
- High
- Medium
- Low
- Info
About incident classification types
Alert Logic classifies incidents based on evidence received from monitored assets. The following table lists and defines the possible classification types.
Classification | Description |
---|---|
Application attack | An application attack incident identifies attacks that target application-specific vulnerabilities. Alert Logic creates an application attack incident when an attacker attempts to compromise an application with a buffer overflow, race condition, directory traversal, SQL injection, cross-site scripting, or /usr/bin/perl or other UNIX command attempts. |
Brute force | A brute force incident identifies repeated authentication attempts and related activities. Alert Logic triggers a brute force incident when sufficient events indicate attempts to systematically compromise a system by brute force guessing valid user name and password combinations. |
Denial-of-service |
A denial-of-service incident, which includes denial-of-service (DoS) attacks and distributed denial-of-service (DDoS) attacks, identifies an attempt to make computer resources or services unavailable either temporarily or indefinitely. Attackers typically use DoS and DDoS either to prevent e-commerce retailers from conducting business, or to send a social message. Alert Logic creates a denial-of-service incident when events indicate this type of attack. |
Info leak | An information leak incident is a generally successful recon attempt. Alert Logic creates an information leak incident when events indicate attempts at reconnaissance activities. For example, port scans used to identify open and closed ports or obtaining information from a secure system can trigger an incident. For more information about reconnaissance activities, see Recon. |
Log policy |
A log policy incident is triggered when Alert Logic creates a log policy incident automatically, based on selected correlated log messages and specific conditions you define.
For example, you can specify that Alert Logic identify log messages containing five failed login events within a 60-second time period, and then create a log policy incident. |
Log Review | Log Review incidents come from the Alert Logic Log Review service. Some incidents are escalated by an Alert Logic analyst, and the rest appear as info level incidents. |
Misconfiguration | Alert Logic triggers a misconfiguration incident when events indicate that a system is incorrectly configured. Attackers can use the misconfiguration to compromise the system. |
Policy violation | A policy violation incident identifies activities that violate the acceptable use policies of most companies. These activities include: viewing inappropriate material, peer-to-peer activity, and firewall policy changes. |
Recon | A recon incident identifies events that indicate reconnaissance activities against a network or set of hosts to evaluate them as a target. The activities that trigger this incident include gathering information about a server operating system, software versions, or the presence of debugging or demonstration scripts. |
Suspicious activity | A suspicious activity incident identifies activity not included in another category that requires further research. Alert Logic creates a suspicious activity incident when anomalous activities, which could indicate a compromise, occur.
For example, the addition of a new domain administrator without the intent and knowledge of existing administrators could indicate an attacker added the administrator role to gain control over the environment or to provide a backdoor entry into the systems. |
Trojan activity | A Trojan activity incident identifies activity that indicates a host is infected by a Trojan horse or other type of backdoor malware, which masquerades as a legitimate program but actually steals information or harms the system. |
Worm activity | A worm activity incident identifies hosts that display signs of worm infection. A computer worm is self-replicating malware that uses a network to propagate and copy itself to other nodes, with or without your intervention. A worm typically uses a known vulnerability, and can cause damage by altering the infected system and consuming valuable network bandwidth. |
About detection sources
Alert Logic detection sources convey the source of the incident. The following table lists and defines the possible detection sources.
Detection Source | Description |
---|---|
Correlation Rules | You can define correlation rules to perform your own analysis of log messages and configure the correlation to generate an incident. For more information, see Correlations and Notifications. |
Network IDS | The Network Intrusion Detection System (Network IDS) monitors your deployments and generates incidents when it detects security threats such as brute force attacks, privilege escalation, and ransomware. |
Manual | The Manual detection source is for incidents created manually from the Log Search page in the Alert Logic console. For more information, see Search: Log Messages. |
Firewall | Alert Logic can detect and generate firewall security incidents from log data collected from third-party firewall application resources. |
Log Mgmt | Alert Logic generates incidents when the Log Management service detects suspicious activity such as unauthorized privilege escalations, brute force attempts, and access activities. |
GuardDuty | Amazon GuardDuty is a continuous security monitoring service that you can integrate with Alert Logic. GuardDuty uses security logic and AWS usage statistics techniques to identify unexpected and potentially unauthorized and malicious activity, like escalations of privileges, uses of exposed credentials, or communication with malicious IPs, URLs, or domains. For more information, see Integrate Amazon GuardDuty Findings into Cloud Insight Essentials Incidents. |
