Biometrics is the recognition of a person by the measurement of their biological characteristics. For instance, users identifying themselves to a computer or constructing by their fingerprint or voice is treated as biometrics identification.Biometric devices authenticate users to access control systems through some variety of personal identifier including a fingerprint, voiceprint, iris scan, retina scan, facial scan, or signature dynamics. The best thing about using biometrics is that end-users do not lose their personal identifier. It is complex to leave the fingers at home. However, biometrics have not caught on as fast as originally anticipated because of the false positives ... Read More

Authentication is any procedure by which it can test that someone is who they claim they are. This generally contains a username and a password, but can involve some other method of demonstrating identity, including a smart card, retina scan, voice recognition, or fingerprints. Authentication is similar to displaying the drivers license at the ticket counter at the airport.Authorization is discovering out if the person, once recognized, is allowed to have the resource. This is generally decided by discovering out if that person is a part of a specific group, if that person has paid admission, or has a specific ... Read More

Access control is a data security procedure that allows organizations to handle who is authorized to access corporate information and resources. Secure access control uses policies that tests users are who they claim to be and provide proper control access levels are granted to users.An Access Control system generally involves locked gates, doors or barriers which can be opened utilizing identity authentication methods such RFID access cards, pin codes, face recognition, finger prints or smartphones to enable entry to a building or specific area.Access control includes data and physical access protections that strengthen cybersecurity by handling user authentication to systems. ...

Mandatory access control is access control policies that are decided by the system and not the application or data owner. Mandatory Access Control (MAC) is a group of security policies constrained according to system classification, configuration and authentication. MAC policy management and settings are created in one secure network and defined to system administrators.MAC defines and provides a centralized enforcement of confidential security policy parameters. Mandatory access control creates strict security policies for single users and the resources, systems, or data they are enabled to access. These policies are controlled by a management; single users are not given the authority ... Read More

Access Control is an approach of security that controls access both physically and virtually unless authentication credentials are supported. Access control generally defined restricting physical access to a facility, building or room to authorized persons. This can be used to be enforced generally through a physical security guard.An Access Control system generally involves locked gates, doors or barriers which can be opened using identity authentication approaches such as RFID access cards, pin codes, face recognition, finger prints or smartphones to enable entry to a building or specific area.Access control includes data and physical access protections that strengthen cybersecurity by handling ...

Visitor management is any procedure that provides an organization maintain track of the people that visit their areas. Policies can vary by organization, facility type, industry, or geographic areas.For several organizations, simply collecting the visitor’s name is adequate, but others have larger security requirements such as badges, legal files, employee escorts, and more.Visitor management systems are tools that provide organizations generate or carry out their visitor management policies. As organisation realize the value of visitor management, some are updating from the paper and pen sign-in sheet to a digital visitor management system that can support them do much more.Visitor management ...

There are several types of intrusion prevention system which are as follows −Host-based IPS (HIPS) − A host-based IPS is one where the intrusion-prevention application is local on that specific IP address, generally on a single device. HIPS compliments traditional finger-print-based and heuristic anti-virus detection approaches, because it does not need continuous upgrades to stay ahead of new malware.A comprehensive use of system resources can be a disadvantage of current HIPS, which integrate firewall, system-level action control and sandboxing into a coordinated disclosure net, on top of a traditional AV product.This extensive protection designs can be warranted for a laptop ...

An Intrusion Prevention System is a network security device that monitors network and system activities for malicious or unwanted behavior and can react to block or avoid those activities.Network-based IPS will work in-line to monitor all network traffic for malicious program or attacks. When an attack is identified, it can drop the offending packets while still enabling all other traffic to pass. Intrusion prevention technology is treated by some to be a development of intrusion detection (IDS) technology.Intrusion Prevention Systems (IPS) derivative in the late 1990s to resolve ambiguities in passive network monitoring by locating detection systems in-line. Early IPS ... Read More

An intrusion detection system (IDS) is an app or device that monitors inbound and outbound network traffic, continuously analyzing events for changes in patterns, and alerts an administrator when it identify unusual behavior. An administrator can reviews alarms and takes actions to delete the threat.For example, an IDS can inspect the data carried by network traffic to look if it includes known malware or other malicious content. If it can identify this type of threat, it sends an alert to the security team so they can investigate and remediate it. Because your team receives the alert, they should act rapidly ... Read More

An intrusion detection system (IDS) is software specifically develop to monitor network traffic and find irregularities. An IDS is designed to detect network traffic and match traffic designs to known attacks. Through this method, sometimes known as pattern correlation, an intrusion prevention system can determine if unusual event is a cyberattack.Because suspicious or malicious activity is found, an intrusion detection system will send an alarm to specified technicians or IT administrators. IDS alarms allows us to rapidly start troubleshooting and identify root sources of problems, or discover and stop harmful agents in their tracks.Intrusion Detection System (IDS) technology is an ...
