Which of the following is a common method of implementing Network Access Control?Firewalls based access rulesIPS based protection rulesIP based access controlPort-based access control
Solution
All of the options mentioned are common methods of implementing Network Access Control:
-
Firewalls based access rules: Firewalls are a basic and crucial part of network security. They act as a barrier between the trusted internal network and untrusted external networks. A firewall controls access to the resources of a network through a positive control model, which states that only traffic defined in the firewall policy is allowed onto the network; all other traffic is denied.
-
IPS based protection rules: Intrusion Prevention Systems (IPS) also contribute to network access control. They can identify malicious activity, log information about this activity, attempt to block/stop it, and report it.
-
IP based access control: This is a method where access to a network or specific resources on the network is granted or denied based on the IP address of the device trying to gain access.
-
Port-based access control: This is a security feature often found in network devices like switches. It allows the device to control access to its network based on the physical connection (i.e., the specific port) that a device is connected to.
Each of these methods has its own strengths and weaknesses, and they are often used in combination to provide layered security.

how firewalls are used s security control and explain their types
Access control is a method of limiting access to a system or to physical or virtual resources. It is a process by which users can access and are granted certain prerogative to systems, resources or information. Access control is a security technique that has control over who can view different aspects, what can be viewed and who can use resources in a computing environment. It is a fundamental concept in security that reduces risk to the business or organization. To establish a secure system, electronic access control systems are used that depend on user credentials, access card readers, auditing and reports to track employee access to restricted business locations and areas. These systems include access control panels to prohibit entry to sensitive areas like alarms and lock down areas to prevent unauthorized access or operations. Access control systems perform identification, authentication, and authorization of users and entities by evaluating required login credentials that may include passwords, pins, bio-metric scans or other authentication factors. There is multi-factor authentication which requires two or more authentication factors which is often an important part of the layered defense to protect access control systems. Authentication Factors:Password or PINBio-metric measurement (fingerprint & retina scan)Card or Key
