What is the name of the kernel component that uses the iptables rules to filter network traffic?
system-config-firewall (FEDORA) or system-config-securitylevel (RHEL), "that is where you build you firewall"
the netfilter component is a set of tables that hold rules that the kernel uses to control network packet filtering. "Fedora and RedHat Enterprise Linux... fifth edition"
What else can I help you with?
What component is defective when hyt tc500 has weak rx or no rx?
Crystal Filter
Is a saw filter an active component?
No, SAW filters are completely passive devices. You cannot get gain from a SAW filter, and they obey the rules of reciprocity (i.e. S12 = S21).
What are the types of harmonic filters in ups?
Basically they are of 2 types 1) Active filter - For low voltage network 2)Passive filter
Which is an example of techcinial control?
An example of a technical control is the use of firewalls to protect a network from unauthorized access. Firewalls monitor and filter incoming and outgoing network traffic based on predetermined security rules, helping to prevent cyber threats. Other examples include encryption of data in transit and at rest, as well as intrusion detection systems that identify and respond to potential security breaches.
Which harmonics is suppressed by the front end filter of a distortion factor meter?
fundamental wave component is filtered in the front end.
What is the simplest way to filter network traffic?
The simplest way to filter network traffic is by using a firewall, which can be configured to allow or block traffic based on predefined rules such as IP addresses, ports, and protocols. Additionally, implementing access control lists (ACLs) on routers can also help in filtering traffic by specifying which packets are permitted or denied. For more granular control, using intrusion detection systems (IDS) can help identify and filter malicious traffic.
Which two characteristic of network traffic are being monitored if a network technician configures the company firewall to operate as a packet filter Choose two?
*ports*protocols
A network technician must reduce the amount of broadcast traffic on the network while maintaining full connectivity between all different network segments Which device should the administrator deploy?
This device is called a ROUTER. Routers are by default configured to not pass the broadcast traffic to another networks to which it connects. But by some means it could be also a SWITCH - sometimes it can be configured to filter different type of network traffic.
How does a router filter traffic?

What the layer of hub?
The layer of hub refers to a networking component that connects multiple devices within a local area network (LAN). It operates at the physical layer of the OSI model, primarily functioning as a basic data distributor by broadcasting incoming data packets to all connected devices. Hubs are relatively simple devices and do not filter or manage traffic, which can lead to collisions and reduced network efficiency compared to more advanced devices like switches. While largely outdated, hubs were foundational in the evolution of network architecture.
What is a network filter used for?
A personal network filter used to restrict access to particular Internet resources from a local computer.
What is the simplest component in a filter circuit called?
capacitor
How do you prevent DDoS attack?
You can prevent a DDoS attack by using multiple layers of defense: Use firewalls and intrusion prevention systems to filter malicious traffic. Set up rate limiting so attackers can’t flood your server with requests. Rely on Content Delivery Networks (CDNs) or DDoS protection services that absorb large traffic spikes. Keep systems updated to reduce exploitable weaknesses. In short, combining strong network security tools with cloud-based protection helps stop attacks before they disrupt your services.
Which blood component do the kidney's filter?
Red blood cells
What Are The Disadvantages of repeater?
It can't filter network traffic. Data, sometimes referredto as bits, arriving at one port of a repeater gets senout to other port Data gets passed along by a repeater to all other LANsegments of a network regardless of whether it needs to go there or not
What can be done to reduce the broadcast traffic?
To reduce broadcast traffic, network segmentation can be implemented through the use of VLANs, which limits broadcast domains and confines broadcast messages to specific groups. Additionally, configuring routers and switches to filter or limit broadcast packets can help manage their flow. Implementing protocols like IGMP snooping can also optimize multicast traffic and minimize unnecessary broadcasts. Lastly, regularly reviewing and optimizing network configurations can help identify and eliminate sources of excessive broadcast traffic.
What is bridge connection?
A bridge connection refers to a network architecture that links multiple devices within a local area network (LAN), allowing them to communicate and share resources. It operates at the data link layer (Layer 2) of the OSI model, using MAC addresses to forward data frames between segments. This connection helps reduce network traffic and improve efficiency by dividing larger networks into smaller, manageable segments. Bridges can also filter and manage traffic to enhance overall network performance.
