What is the process of Signature Verification in information security?
A biometric technique that uses characteristics of a person’s signature (such as pressure, pen lifts, speed and direction of pen strokes) to authenticate identity. Signature is less efficient than some multiple biometrics (e.g., fingerprints, iris) but is famous in file authentication applications that have been used written signatures. Some growth can be fueled by the maintenance of pen-based devices (e.g., the PalmPilot) that can match as a signature input tablet.Signature verification technology is the determination of an individual’s written signature, such as the speed, acceleration cost, stroke length and pressure applied during the signature. There are diverse approach to capture ...
Read MoreHow Does Voice Biometrics Work in information security?
Voice biometrics is the science of using a person's voice as a uniquely identifying biological natures to authenticate them. Voice biometrics also enhance the user experience by eliminating frustration associated cumbersome login processes and lost and stolen credentials.Voice biometrics, creates the person’s voice to test or identify the person. It confirms and recognizes the speaker. A microphone on a standard PC with software is required to test the unique traits of the person. It is generally used in telephonebased applications.Voice verification is easy to use and does not require a big deal of user education. It can enroll the user ...
Read MoreWhat are the Biometric techniques used for identification?
There are several techniques of biometric which are as follows −Face Recognition − The biometric system can recognize a person by the face. This technology services by analyzing particular traits in the face including the distance among the eyes, width of the nose, position of cheekbones, jaw line, chin, unique shape, pattern etc. These systems involves dimensions of the eyes, nose, mouth, and other facial characteristics for identification.Face recognition captures traits of a face either from video or still image and transforms unique traits of a face into a group of numbers. These data assembled from the face are combined ...
Read MoreWhat is User Identification and Authentication in information security?
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 MoreWhat is Mandatory access control in information security?
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 MoreWhat is an Access Control in Information Security?
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 ...
Read MoreWhat is a Visitor Control in Information Security?
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 ...
Read MoreWhat are the types of Intrusion Prevention System?
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 ...
Read MoreWhat is an Intrusion Prevention System in information security?
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 MoreWhat are the types of Intrusion-Detection Systems in information security?
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 ...
