What is a software or hardware designed to filter out suspicious packets attempting to enter or leave a computer?
firewall
If a firewall does nothing more than filter packets, at what layer of the OSI model does it operate?
Network Layer
A network administrator needs to restrict access to the network Which type of firewall allows only those packets that are part of a known connection?
The firewall that only allows packets of registered connection is called packet filter. It is also the central piece in firewalling.
What is stateful packet inspection?
Incoming packets must be legitimate responses to requests from internal hosts. Unsolicited packets are blocked unless permitted specifically. SPI can also include the capability to recognize and filter out specific types of attacks such as DoS.
What is a software routine which also acts as a filter that blocks certain type of incoming and outgoing traffic while enabling other types called?
firewall
What is transparent firewall?
Since the fundamental task of a firewall is to filter packets, the weak point in its traditional behavior is the fact that it also must route packets after a decision is made. Can the model be simplified? Of course it can, and the answer comes by stepping down a layer in the OSI model. Instead of the device handling packets at layer 3 (network), what if it merely inspected frames and moved them to the proper interface? Sound familiar? This type of device would continue to filter packets, but operate at layer 2 (data link), like a bridge. Such a device has come to be known by several names: a transparent, in-line, shadow, stealth or bridging firewall. ranajoy karmakar@gmail.com ccna,network engineer
What are the components of firewall?
A firewall typically consists of three main components: the policy engine, which defines the rules and regulations for traffic control; the packet filter, which examines incoming and outgoing data packets based on those rules; and the logging and reporting system, which monitors and records traffic activity for analysis and security auditing. Additionally, some firewalls may include intrusion detection and prevention systems (IDPS) to enhance security by identifying and blocking potential threats.
Which three statements describe ACL processing of packets?
Access Control Lists (ACLs) filter packets based on predefined rules applied to incoming or outgoing traffic. When a packet arrives, the ACL is processed in a sequential manner, evaluating each rule until a match is found or the end of the list is reached. If a packet matches a rule, the specified action (permit or deny) is applied, and further processing stops. If no rules match, a default action (usually to deny) is typically enforced.
