List four technique used by firewalls to control access and enforce a security policy?
Techniques used by firewall:
There are four general techniques that firewall use to control access and enforce the sites security policy:
- Service Control:
Determines the types of internet services that can be accessed, inbound or outbound.
Firewall may filter traffic on the basis of IP address and TCP port number.
It may provide proxy software that receives and interprets each service request before passing it on.
It may host the server software itself such as a web or mail service.
- Direction control:
Determines the direction in which particular service request may be initiated and allowed to flow through firewall.
- User control:
Control access to a service according to which user is attempting to access it. This feature is applied to users inside the firewall perimeter. It may also be applied to incoming traffic from external users. But it requires some form of secure authentication technology.
- Behavior control:
Controls how particular services are used. For eg.the firewall may filter email to eliminate spam or it may enable external access to only a portion of the information on a Local web server.

What does enforcing sercurity do in Linux?
Enforcing security in Linux involves implementing measures that protect the system from unauthorized access and vulnerabilities. This can include setting permissions for files and directories, employing security modules like SELinux or AppArmor to enforce mandatory access controls, and regularly applying updates to address security vulnerabilities. Additionally, configuring firewalls and intrusion detection systems helps to monitor and control network traffic, enhancing overall system security. These measures collectively ensure the integrity, confidentiality, and availability of system resources.
Describe how the various type of firewalls interact with the network traffic at various levels of the OSI model?
Firewalls interact with network traffic at various levels of the OSI model primarily at the network, transport, and application layers. Packet-filtering firewalls operate at the network layer, inspecting headers to allow or block traffic based on IP addresses and port numbers. Stateful inspection firewalls function at both the network and transport layers, maintaining state information about active connections to make more informed filtering decisions. Application layer firewalls, on the other hand, analyze the data within the packets, scrutinizing content and application-specific protocols to enforce more granular security policies.
How do the United Nation enforce rules?
The United Nations enforce rules through the resolutions of the Security Council.
What devices are your front line of defense against attacks being launched from outside the company network?
The front line of defense against external attacks typically includes firewalls, intrusion detection and prevention systems (IDPS), and secure web gateways. Firewalls monitor and control incoming and outgoing network traffic based on predetermined security rules, while IDPS actively analyze traffic for suspicious activity. Additionally, secure web gateways help filter malicious web content and enforce company policies, providing an essential layer of protection against threats from the internet. Together, these devices form a comprehensive security perimeter to safeguard the company's network.

How can a DNS firewall improve networking security for your business?
Implementing a DNS firewall can significantly enhance networking security for businesses. By filtering and blocking malicious DNS queries, it prevents access to known threats like phishing sites and malware-infected domains. This proactive filtering mechanism reduces the risk of infections, data breaches, and unauthorized access attempts. DNS firewalls also enforce security policies, ensuring compliance with industry regulations and protecting sensitive information. They improve overall network performance by redirecting users away from potentially harmful sites and towards secure resources. Operating at the DNS level, these firewalls provide a critical layer of defense, fortifying network security against evolving cyber threats effectively.
How do I implement security in Tableau?
Tableau provides role-based access control and row-level security. However, ensuring compliance across large environments requires automation. Datagaps DataOps Suite helps enforce security policies by auditing data access, detecting anomalies, and monitoring user activity.
How do you think we should control enforce cybercrime?
One of the first steps you can take is to add firewalls to your computer so that scams and viruses are less likely to "bug" your computer. Also, make sure not to give out your personal information and only shop on secure websites. These steps will help ensure that some negative activity does not occur.
