logical vs remote access

What is logical access?

Logical access ranges from this type of limited interaction to near-complete access through remote control software. Programs such as Windows' Remote Desktop Connection, as well as commercial alternatives including TeamViewer, GoToMyPC and LogMeIn, provide a type of logical access to computers that mimics physical access.

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.

How do logical access controls protect hardware from remote access?

Businesses, organizations and other entities use a wide spectrum of logical access controls to protect hardware from unauthorized remote access. These can include sophisticated password programs, advanced biometric security features, or any other setups that effectively identify and screen users at any administrative level.

What are the three types of logical access control?

The three models commonly used in logical access control include discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC). DAC – Is a control mechanism where the user explicitly allows access to other users or programs that the user has ownership or control over.

What is the difference between logical 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 meant by logical access?

Logical access control is defined as restricting virtual access to data; it consists of identification, authentication, and authorization protocols utilized worldwide to protect hardware from unauthorized access, including password programs, smart cards, or tokens to identify and screen users and access levels.

What is an example of logical access control?

Examples of logical controls are passwords, network firewalls, access control lists and data encryption.

What is the difference between logical and physical security?

Protecting the people involves a combination of physical and logical security. Physical security keeps them safe by allowing only authorized individuals into the building. Logical security protects their computers and data from unauthorized access.

What are the three types of access control?

Three main types of access control systems are: Discretionary Access Control (DAC), Role Based Access Control (RBAC), and Mandatory Access Control (MAC). DAC is a type of access control system that assigns access rights based on rules specified by users.

What does logical mean in computers?

The term "logic" is not the same as "logical." Logic refers to algorithms and operational sequences; whereas, "logical" refers to a higher-level view of hardware, software or data that is not tied to physical structures (see logical vs. physical).

What are the types of logical access controls?

The three models commonly used in logical access control include discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC).

What is logical data security?

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.

Which of the following is not a logical access control?

Explanation. An ID Badge is not a logical control. It is used to help enforce physical controls.

What is a logical threat?

While physical threats may include theft, vandalism, and environmental damage, logical threats are those that may damage your software systems, data, or network without actually damaging your hardware.

What is the logical access path?

Logical access in IT is often defined as interactions with hardware through remote access. This type of access generally features identification, authentication and authorization protocols.

Which is more important for computer systems physical security or logical security?

While physical security is undeniably important, so is logical system security, which manages access to computer systems. In fact, the two can actually complement each other in more ways than one. At least if it's done right.

What is logical access path?

Logical access in IT is often defined as interactions with hardware through remote access. This type of access generally features identification, authentication and authorization protocols.

What is the meaning of physical access?

Physical access refers to actual hands-on, on-site access to computer and network hardware, or other parts of a hardware installation.

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 administrative access control?

Access control administration is the collection of tasks and duties assigned to an administrator to manage user accounts, access, and accountability. A system's security is based on effective administration of access controls.

What is remote desktop access?

Programs such as Windows' Remote Desktop Connection, as well as commercial alternatives including TeamViewer, GoToMyPC and LogMeIn, provide a type of logical access to computers that mimics physical access. Unlike logging in to a website, these programs allow a remote user to interact with a PC as if sitting in front of its monitor and keyboard. Some remote control programs also include features such as file transfers and presentation tools. Though these programs have security features, such as passwords and restrictions, you should only let people you trust connect to your machine through remote access -- a malicious user can very quickly damage a system when given remote control over it.

What is physical access?

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. Though the two types of access offer some of the same features, ...

What is access control?

Access control is the selective restriction of access to a place or other resource. It is used to regulate who is able (or not able) to view, access, or use specific resources and/or information. The two main types are physical and logical.

What is physical access control?

Physical access control refers to the selective restriction of access to a location, a task most often accomplished with a variety of security methods that control and track who is entering a location and who is leaving.

What is a key fob?

Key fobs have gone through many iterations over the years; the most up-to-date versions now operate primarily over the much more secure radio frequency identification (RFID) tag, which allows the exchange of data through electromagnetic waves. Identiv’s Aperio Wireless Lock Integration with Hirsch Velocity provides high-security access control delivered wirelessly.

What is a logical access control?

Logical access control is defined as connections with hardware through remote access generally featuring identification, authentication, and authorization protocols. This approach is the polar opposite of physical access, which refers to interactions with hardware in the physical environment, where equipment is stored and used.

Why do organizations use logical access controls?

Organizations worldwide use a broad spectrum of logical access controls to protect hardware from unauthorized access, including password programs, biometrics, smart cards, or tokens to identify and screen users and access levels. The approach to logical access controls used in businesses usually is dependent on the business leaders or IT administrators. But in government applications, federal agencies must comply with federal guidelines to protect the data being transferred.

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.

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 local access?

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.

What is the logical progression of an attacker?

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.

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?

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.
