HIPS - Host Intrusion Prevention System
|
Changes to HIPS settings should only be made by an experienced user. Incorrect configuration of HIPS settings can lead to system instability. |
The Host Intrusion Prevention System (HIPS) protects your system from malware and unwanted activity attempting to negatively affect your computer. HIPS utilizes advanced behavioral analysis coupled with the detection capabilities of network filtering to monitor running processes, files and registry keys. HIPS is separate from Real-time file system protection and is not a firewall; it only monitors processes running within the operating system.
You can configure HIPS settings in Advanced setup > Detection engine > HIPS > Host Intrusion Prevention System. The HIPS state (enabled/disabled) is shown in the ESET NOD32 Antivirus main program window > Setup > Computer protection.
Host Intrusion Prevention System
Enable HIPS—HIPS is enabled by default in ESET NOD32 Antivirus. Turning off HIPS will disable rest of the HIPS features like Exploit Blocker.
Enable Self-Defense—ESET NOD32 Antivirus uses the built-in Self-defense technology as a part of HIPS to prevent malicious software from corrupting or disabling your antivirus and antispyware protection. Self-defense protects crucial system and ESET's processes, registry keys and files from being tampered with.
Enable Protected Service—Enables protection for ESET Service (ekrn.exe). When enabled, the service is started as a protected Windows process to defend attacks by malware.
Enable Advanced memory scanner—Works in combination with Exploit Blocker to strengthen protection against malware that has been designed to evade detection by antimalware products through the use of obfuscation or encryption. Advanced memory scanner is enabled by default. Read more about this type of protection in the glossary.
Enable Exploit Blocker—Designed to fortify commonly exploited application types such as web browsers, PDF readers, email clients and Microsoft Office components. Exploit blocker is enabled by default. Read more about this type of protection in the glossary.
Deep Behavioral Inspection
Enable Deep Behavioral Inspection—Another layer of protection that works as a part of the HIPS feature. This extension of HIPS analyzes the behavior of all programs running on the computer and warns you if the behavior of the process is malicious.
HIPS exclusions from Deep Behavioral Inspection—Enables you to exclude processes from analysis. To ensure that all processes are scanned for possible threats, we recommend only creating exclusions when it is absolutely necessary.
Ransomware shield
Enable Ransomware shield—Another layer of protection that works as a part of HIPS feature. You must have the ESET LiveGrid® reputation system enabled for Ransomware shield to work. Read more about this type of protection.
Enable Intel® Threat Detection Technology—Helps to detect ransomware attacks by utilizing unique Intel CPU telemetry to increase detection efficacy, lower false positive alerts, and expand visibility to catch advanced evasion techniques. See the supported processors.
HIPS settings
Filtering mode can be performed in one of the following modes:
Description |
|
|---|---|
Automatic mode |
Operations are enabled with the exception of those blocked by pre-defined rules that protect your system. |
Smart mode |
The user will only be notified about very suspicious events. |
Interactive mode |
User will be prompted to confirm operations. |
Policy-based mode |
Blocks all operations that are not defined by a specific rule that allows them. |
Learning mode |
Operations are enabled and a rule is created after each operation. Rules created in this mode can be viewed in the HIPS rules editor, but their priority is lower than the priority of rules created manually or rules created in automatic mode. When you select Learning mode from the Filtering mode drop-down menu, the Learning mode will end at setting will become available. Select the time span that you want to engage learning mode for, the maximum duration is 14 days. When the specified duration has passed, you will be prompted to edit the rules created by HIPS while it was in learning mode. You can also choose a different filtering mode, or postpone the decision and continue using learning mode. |
Mode set after learning mode expiration—Select the filtering mode that will be used after learning mode expires. After expiration, the Ask user option requires administrative privileges to perform a change to the HIPS filtering mode.
The HIPS system monitors events inside the operating system and reacts accordingly based on rules similar to those used by the Firewall. Click Edit next to Rules to open the HIPS rules editor. In the HIPS rules window you can select, add, edit or remove rules. More details on rule creation and HIPS operations can be found in Edit a HIPS rule.
