Monitoring Web Application Security
- Policy enforcement settings: A security policy may be deployed inTransparentorBlockingenforcement modes. Depending on your environment you may want to change these settings following the application service's deployment.
- Increased bad traffic: Drill down into traffic details, such as geolocation or malicious requests, or targeted URLs to identify sources of an attack. Based on these results, the security admin can enable strict enforcement for specific objects.
- False Positives: Application service alerts of increased false positives may indicate that enforcement settings are too strict and need adjustment.
- A BIG-IQ data collection device configured for the BIG-IQ device
- The BIG-IP device located in your network and running a compatible software version
- Statistics collection enabled for managed BIG-IP devices
- AVR provisioned on your BIG-IP devices
Web Application Security Charts
- Illegal Transactions Rate (TPS)
- The average number of illegal transactions per second that were identified by the Web Application Security profile. These transactions were detected based on the violation rating and your Web Application Security policy's action settings. Increases in illegal traffic over time can indicate an increase in attacks to your applications, or it can indicate an overly-strict protection policy. The current protection mode is indicated by Blocked or transparent transactions. You can use theViolation Ratingdimension to filter violations above a certain threat level. This will allow you to identify specific violations types that were detected.A single illegal transaction can include multiple violations. Therefore, comparing the number of illegal transactions vs the number of violations may not accurately reflect your system's status. It is recommended to primarily evaluate the number of illegal transactions.
- Transactions Rate by Violation Rating (TPS)
- The average number of transactions per second by the detected threat level assigned by your Web Application Security policy. The threat level of the traffic is shown in ascending order; fromLegaltoMalicious.
- Top 6 Violations (Violations/s)
- The six types of violations most commonly detected (per second). Violation information can be useful in adjusting your Web Application Security policy for optimized protection against the most common attacks.
Security Dimensions and Metrics
Web Application Security Dimensions
- BIG-IP Host Names
- The name of each BIG-IP system that processed the monitored transactions.
- BIG-IP Blade Numbers
- The individual blades (by number) for all monitored BIG-IP devices.
- The name of each application reporting HTTP traffic data.
- Application Services
- The name of each HTTP application service reporting transaction data.
- Virtual Servers
- The name of each virtual server that processes monitored transactions.
- ASM Policy Names
- The names of the Web Application Security (ASM) policies that protect the virtual servers currently processing application traffic.
- The enforcement applied to a detected attack signature. These actions include:
- Violation Ratings
- The rating assigned to traffic by the Web Application Security policy. The assigned ratings include:
- Legal, normal traffic that does not contain any threat indicators.
- Legal (Staging), traffic that is tentatively detected as legal during the policy builder process. The relevant settings in the security policy are in staging.
- Likely F.P., traffic may present a security threat, but is likely a false positive.
- Illegal, traffic that contains known violations, or abnormalities, that pose a threat to the application's performance.
- Malicious, traffic that contains known threat actors.
- Network Protocols
- The network protocol (HTTP, HTTPS) in the transaction.
- Client IPs
- The client IP address that initiated the HTTP request that was processed by the BIG-IP system.
- Attack Types
- The general category of application-layer attack, as identified by the Web Application Security policy.
- The types of traffic violations, as detected by your Web Application Security policy.
- Virus Names
- The names of known viruses detected.
- Client Device IDs
- IP Reputation
- The IP categories configured for IP Intelligence. This dimension is relevant to users who have configured an ASM policy with IP Intelligence.
- The country listed in the HTTP request that was processed by the BIG-IP system.
- User Name
- The client login name, based on information submitted from a login page. This information is available when Web Application Service is paired with Access service.
- Session ID
- The unique identifier of an HTTP session between the client and the application. This information is stored along with other client data, such as device ID.
- The URL that initiated the HTTP request that was processed by the BIG-IP system.
- Response Code Families
- The class of the HTTP response result received by the BIG-IP system.
- The HTTP method included in the HTTP request received by the BIG-IP system.
