Which system monitors local system operation and local network access for violations of a security policy?
Which system monitors local system operation and local network access for violations of a security policy?
The system referred to in the question is a host-based intrusion detection system (HIDS). HIDS is specifically designed to monitor the internals of a computing system for suspicious activity and policy violations, which includes local system operation as well as network access. A host-based firewall is used to control incoming and outgoing network traffic on a host system but does not monitor for policy violations or system operations. Systems-based sandboxing isolates applications to prevent harm but does not monitor for violations. Antivirus software focuses on detecting and removing malware, not on monitoring system and network operations for policy violations.
i think that "A.host-based intrusion detection". HIDS is capable of monitoring the internals of a computing system as well as the network packets on its network interfaces. Host-based firewall is a piece of software running on a single Host that can restrict incoming and outgoing Network activity for that host only.
"A" is correct. The question is copy and past of Wikipedia definition: An intrusion detection system (IDS)[1] is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms. https://en.wikipedia.org/wiki/Intrusion_detection_system
Answer is A An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations.
A host based firewall does not monitor local system operations. A firewall is no more than an ACL matching traffic in and out of a system based on how it's configured. A significant advantage of HIPS is that it can monitor operating system processes. "A HIPS often monitors memory, kernel, and network state, log files, ... protects system integrity by detecting changes to critical operating system files."
In this case its HIDS and not HIPS, which one could argue would only make choice A even stronger seeing that a HIDS only monitors (both network and system files) whilst a firewall monitors network only but also intervene and blocks, which is more then just monitoring.
The key word is "monitors". And it's IDS work.
It says security policies. In the firewall the concept of security policies is handled. I agree with the answer
A. is the best answer HIDS is capable of monitoring the internals of a computing system as well as the network packets on its network interfaces. Host-based firewall is a piece of software running on a single Host that can restrict incoming and outgoing Network activity for that host only.
IDS Global detection, Firewall Local.. and i agree with the answer.. no doubt bro make it simple
HIDS monitors local system, firewall not. Answer is A
Should be A imho, key word "monitors"
Host-based firewall is a piece of software running on a single Host that can restrict incoming and outgoing Network activity for that host only.
A host intrusion detection system uses rules and policies in order to search your log files, flagging those with events or activity the rules have determined could be indicative of potentially malicious behavior.
Keyword: "Monitors" - It is an IDS function. - An Intrusion Detection System (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations. - A host based firewall does not monitor local system operations. A firewall is no more than an ACL matching traffic in and out of a system based on how it's configured.
The answer is A. Host-based intrusion detection (HIDS) is a security system that monitors a computer system for malicious activity or policy violations. HIDSs can be used to detect a variety of threats, including unauthorized access, malware, and data exfiltration. Systems-based sandboxing is a security technique that isolates applications in a controlled environment to prevent them from causing harm to the host system. Host-based firewall is a security system that controls incoming and outgoing network traffic on a host system. Antivirus is a software application that detects and removes malware from a computer system.
