What is the difference between application level gateway and hardware level gateway in information security?
Application-level GatewayAn application gateway or application level gateway (ALG) is a firewall proxy which offers network security. It filters incoming node traffic to certain specifications which define that only transmitted network application information is filtered. Such network applications such as File Transfer Protocol (FTP), Telnet, Real Time Streaming Protocol (RTSP) and BitTorrent.An application layer gateway also known as an application proxy gateway. It can perform a several functions at the application layer of an infrastructure, generally known as layer 7 in the OSI model. These functions can include address and port translation, resource allocation, software response control, and synchronization of ...
Read MoreHow firewalls control the in and out flowing traffic of the network?
A firewall can be represented as a special type of network security device or a software program that monitors and filters incoming and outgoing network traffic based on a represented group of security rules. It facilitate as a barrier between internal private networks and external sources (including the public Internet).The objective of a firewall is to enable non-threatening traffic and prevent malicious or unwanted data traffic for securing the computer from viruses and attacks. A firewall is a cybersecurity tool that filters network traffic and provide users block malicious application from accessing the web in infected computers.Firewalls can be executed ...
Read MoreWhat is RBAC in information security?
RBAC stands for Role-based access control. It also known as role-based security. It is an access control method that creates permissions to end-users depends on their role within the organization. RBAC supports fine-grained control, providing a simple, controllable method to access administration that is less error-prone than individually assigning permissions.This can decrease cybersecurity risk, protect sensitive information, and provides that employees can only access information and perform actions they required to do their jobs. This is referred to as principle of least privilege.Roles are based on multiple elements in RBAC, such as authorization, responsibility, and job specialization. Organizations generally designate ...

Mainly, it is used in several small portable devices including handheld computers, digital video camcorders, digital cameras, mobile phones, etc.Approximately, more than 8000 multiple models and over 400 brands of electronic equipment use SD technology. It measures 32 x 24 x 2.1 mm and weighs approximately 2 grams and is treated a standard for the industry because of widespread ...
Read MoreWhat is the difference between memory card and smart card in information security?
Memory CardA memory card is a type of storage device that can store videos, photos, or other data files. It provide a volatile and non-volatile medium to save data from the inserted device. It is also defined as a flash memory. Generally, it is used in devices like phones, digital cameras, laptops, digital camcorders, game consoles, MP3 players, printers, etc.A memory card is generally used as a primary and portable flash memory in mobile phones, cameras and other portable and handheld devices. PC Cards (PCMCIA) were a predecessor of modern memory cards that were introduced for commercial goals. Besides supporting ...
Read MoreWhat is Host Intrusion Prevention System in information security?
A host-based intrusion prevention system (HIPS) is a system or a program employed to secure critical computer systems including crucial data against viruses and some Internet malware. It is beginning from the network layer all the way up to the application layer, HIPS assure from known and unknown malicious attacks.HIPS regularly verify the features of a single host and the various events that occur within the host for suspicious activities. HIPS can be implemented on several types of machines, such as servers, workstations, and computers.A host-based IPS is one where the intrusion-prevention software is resident on that specific IP address, ...
Read MoreWhat is the process of Risk Transfer in information security?

Risk control provide companies limit lost assets and income. Risk control is an essential component of a company's enterprise risk management (ERM) protocol.Risk control measures are ...
Read MoreWhat are the types of data integrity?
Database integrity defines the validity and consistency of stored information. Integrity is generally defined in terms of constraints, which are consistency rules that the database is not allowed to violate. Constraints can apply to each attribute or they can apply to relationships between tables.Integrity constraints provides that changes (update deletion, insertion) made to the database by authorized users do not result in a loss of data consistency. Therefore, integrity constraints guard against accidental damage to the database.There are various types of data integrity which are as follows −Logical Integrity − In a relational database, logical consistency provides the data remains ...
Read MoreWhat is the difference between data security and data integrity?
Data SecurityData security define the collective measures used to protect and secure a database or database management software from improper use and malicious cyber threats and attacks. Database security is a layer of information security. It is basically concerned with physical protection of information, encryption of information in storage and data remanence issues.Data security is generally defined as the confidentiality, availability and integrity of data. In another terms, it is all of the practices and processes that are in place to provide data isn't being used or accessed by unauthorized individuals or parties. Data security provides that the data is ...
