What is logical access control and how does it work?
Logical access control involves authenticating and authorizing users. This is different than physical access control. Physical access control uses keys and badges. Logical access controls use advanced password programs and advanced biometric security features.
What is the difference between physical access and remote access?
Though the two types of access offer some of the same features, especially in the case of remote control software, physical access grants a user far more control over a system, making it a potential security risk. Most interactions with personal computers occur through physical access.
What are the different types of logical access?
Types of Logical Access. Any non-physical interaction with a computer falls under the category of logical access. Many companies use logical access controls, such as passwords or biometrics, to give employees access to specific features on corporate networks without granting every employee complete control.
What is the difference between physical and logical access?
A man and his kids are on his laptop. In computing, physical access describes any time a user can reach a computer's hardware. Conversely, logical access refers to every other type of computer use, where a user connects to a computer system without being in the same room as the machine.
What is the difference between logical access and physical access?
There are two types of access control: physical and logical. Physical access control limits access to campuses, buildings, rooms and physical IT assets. Logical access control limits connections to computer networks, system files and data.
What is the meaning of logical access?
A logical access control system requires the validation of an individual's identity through some mechanism, such as a PIN, card, biometric, or other token. It has the capability to assign different access privileges to different individuals depending on their roles and responsibilities in an organization.

What are logical security measures?
Logical Security consists of software safeguards for an organization's systems, including user identification and password access, authenticating, access rights and authority levels. These measures are to ensure that only authorized users are able to perform actions or access information in a network or a workstation.
What is subject in access control?
A subject is an active entity that requests access to a resource or the data within a resource. E.g.: user, program, process etc. A resource is an entity that contains the information. E.g.: Computer, Database, File, Program, Printer etc.
What is remote access in Linux?
Remote access is defined as gaining access via the network (for example, a listening service) or other communication channel. Local access is defined as having an actual command shell or login to the system. Local access attacks are also referred to as privilege escalation attacks. It is important to understand the relationship between remote and local access. Attackers follow a logical progression, remotely exploiting a vulnerability in a listening service and then gaining local shell access. Once shell access is obtained, the attackers are considered to be local on the system. We try to logically break out the types of attacks that are used to gain remote access and provide relevant examples. Once remote access is obtained, we explain common ways attackers escalate their local privileges to root. Finally, we explain information-gathering techniques that allow attackers to garner information about the local system so that it can be used as a staging point for additional attacks. It is important to remember that this chapter is not a comprehensive book on UNIX security. For that we refer you to Practical UNIX & Internet Security , by Simson Garfinkel and Gene Spafford (O'Reilly, 2003). Additionally, this chapter cannot cover every conceivable UNIX exploit and flavor of UNIX. That would be a book in itself. In fact, an entire book has been dedicated to hacking Linux Hacking Linux Exposed , by Brian Hatch, James Lee, and George Kurtz (Osborne/McGraw-Hill, 2001). Rather, we aim to categorize these attacks and to explain the theory behind them. Thus, when a new attack is discovered , it will be easy for you to understand how it works, even though it was not specifically covered. We take the "teach a man to fish and feed him for life" approach rather than the "feed him for a day" approach.

What is logical access control?
Logical access controls are the features of your system that enable authorized personnel access to resources. To many folks, distinguishing between logical access control and I&A is confusing. Logical access controls are those controls that either prevent or allow access to resources once a user’s identity already has been established. Once a user is logged in, they should have access only to those resources required to perform their duties. Different user groups usually have access to different resources, which ensures a separation of duties. Describe how the separation of duties occurs. A good portion of this discussion should be about account management. User accounts are usually part of a role-based group. Describe the names of each role and what resources each role has access to. The resources that you will want to take into consideration include systems, directories, network shares, and files. You can summarize this information in a table similar to Table 16.8.
Why do administrators use remote administration?
Because of the dynamic nature of networking and administration , many times administrators will implement remote administration interfaces without regard to who will actually have access to them.
What is access control in healthcare?
Access control is often the first and possibly most robust controls that can be implemented to ensure privacy and security in the healthcare environment. When you think about a typical healthcare environment and all the sensitive information present, you quickly understand the importance of limiting the access to that information to only authorized individuals who need to have access to the information in order to perform their job responsibilities and deliver healthcare services. Although similar in nature, it is important to distinguish between physical and logical access control. Since physical security is often the first line of defense we will start there. Since systems that store sensitive healthcare information are located within the physical walls of healthcare service providers, we can focus on the outside and work our way in. Considering the defense-in-depth security methodology, we are able to achieve our first layer of access control just by limiting physical access to information systems. This does not mean we do not need logical security, but rather we can gain some comfort in knowing that well-designed and properly maintained physical security access controls can deter or prevent unauthorized individuals from being able to physically access sensitive information or healthcare systems. Since we must avoid creating single points of failure and there are some threats that exist regardless of physical security controls, logical access controls are the next layer in effective security and required to support the CIA triad. Logical access controls should be developed to support the system architecture and be implemented at as many layers as possible. This typically means ensuring proper access control at both the network and system level. For example, a healthcare practitioner’s access should be controlled when he or she logs into the network and again when he or she wants to access a particular system hosted on the network. From a more practical and healthcare-focused view, organizations do not want just anyone to be able to view or access patient information. So do organizations just need to implement controls preventing only outsiders from accessing patient records? The answer is no. Just because a person is employed by a healthcare organization does not mean they should be allowed to access sensitive patient information. In fact, effective access control is based on the concept of least privilege (individuals should only be able to access the information required to perform their job – no more, no less) and we will discuss in greater detail a little later. Once a healthcare organization ultimately determines who should be able to access information, the next challenge becomes the “how.” Thinking back to our discussion on defense-in-depth, it makes sense that there is no single approach or access control to accomplish the task. In fact, the more layered the controls, the better. In order to understand how to best implement access controls, let us take a look at the three types of controls: administrative, physical, and technical.
What are the three types of access controls?
Although the three categories work together and can be implemented independently, we recommend the sequence of administrative, physical, and technical and that is the order they will be discussed in this book. Administrative controls, when supported by senior leadership, set the foundation (aka “tone at the top”) for the organization’s access control objectives. These are often “soft” controls based on policies and organizational culture and regulatory requirements. Physical controls are usually the first layer of defense and often provide perimeter support for technical controls. These can range from door locks and ID badge systems to physical partitions separating employee work and patient care areas. Technical controls usually reside at the system level and are the mechanisms in place to support the organization’s privacy and security policies. A common example would be requiring a valid username and password before accessing the system.
Is physical access logical or physical?
The line is often unclear whether or not an element can be considered physical or logical access control. Physical access is controlled by software, the chip on an access card, and an electric lock grant access through software. Thus, physical access should be considered a logical access control.
Which groups have a central repository for access control investigations?
Auditing and forensic groups have a central repository for access control investigations.
Do we see physical access controls?
In the sense of physical access controls, we see these rather frequently as well, although it may not register to us that we are seeing them. Most of us carry around a set of keys that allow us access to our homes, cars, and other devices, and these are the credentials for access to them. Many of us also carry proximity badges that allow us access to our places of employment, schools, and in case of driver’s license places like bars. We can also see the access controls that manage the movement of vehicles in everyday use in vehicle-oriented areas such as parking garages and parking areas at airports, and in the vicinity of high-security areas such as the White House in the United States.
Why is access control important?
It is a vital aspect of any security plan. Access control authenticates and authorizes specific employees to ensure a more secure system. Every good access control system uses a combination of physical access control and logical access control.

Why do government agencies use logical access?
For instance, government facilities, federal agencies, and defense headquarters often deploy high-level logical access security to inhibit external attacks from terrorists, rival governments, and hackers. However, depending on the size, business logical access security are not usually that complex. Most often, an organization’s logical access policies depend on its size, type of industrial transactions, and management processes.
What are the two types of access control systems?
There are two main types of access control systems: physical and logical access control. Both physical and logical access control systems focus on regulating and managing who or what are allowed to access restricted areas and resources.
What is physical access control?
Essentially, physical access control manages, restricts, and limits access to physical locations, premises, and spaces. Such locations may include rooms, offices, facilities, buildings, areas, and IT assets. In a nutshell, physical access control policies permit or deny access to tangible assets. Common examples of physical access control are keys, badges, barricades and fences, RFID doors, fob controlled gates, and password-protected IT systems.
What is access control?
Access control is a broad term used to describe systems that manage, authenticate, and authorize people who can use an asset, tangible, or abstract. Basically, physical and logical access control systems work by identifying users and authenticating their credentials.
What is access control in computing?
In a computing environment, access control is used to regulate who can or cannot view or use computing resources.
Is logical access security complex?
However, depending on the size, business logical access security are not usually that complex. Most often, an organization’s logical access policies depend on its size, type of industrial transactions, and management processes.
What is Logical Access Control?
Logical access control composes policies, procedures, and other activities that are part of the managerial control of an organization. It restricts the use of information to authorized individuals, groups, or organizations.
Why assign RBAC roles?
Assigning RBAC roles simplifies the management of access rights because the role is an abstract entity rather than an individual user or group. For example, a role called “Sales” could be granted permission to read from a database table as well as create new records in the table. Then any number of users could be assigned the “Sales” role for access to that database table.
What is an ACL in a file?
Protect files or directories on a computer system from unauthorized access by using ACLs. In an ACL, users or groups are identified by their full names, e-mail addresses, user IDs, etc. Users have a list of permissions for each object. The permissions include read, write, execute, delete, list directory contents, and change permissions.
What is an ACL?
Access control lists (ACLs) provide a method for controlling access to objects on a computer system. ACLs aim to protect operating system resources, including directories, files, and devices. An ACL is a list of users and groups, along with the permissions they have for an object, such as a file or directory. These permissions include read, write, execute, delete, list directory contents, and change permissions.
What is the process of recording activity in a computer system or network to monitor or maintain accountability of actions taken by users?
Auditing is the process of recording activity in a computer system or network to monitor or maintain accountability of actions taken by users and/or processes acting on behalf of users.
What is authentication in network?
Also, authentication verifies that users are accessing the correct resources on the network using the proper methods.
