A common remote access technology in use today is the IPsec VPN. A piece of software called a VPN client is installed on the end user’s computer and is configured with details about the target network, such as the gateway IP address and a pre-shared security key. Each time the user wants to connect to the corporate network, they start the VPN client, which creates a secure connection to the corporate firewall.
Which operating system do you need for client?
Clients are required to use either the Ultimate or Enterprise versions of Microsoft’s Operating Systems.
Is DirectAccess going to be widespread?
DirectAccess is not going to gain widespread adoption until the OS licensing requirements are revised and the networking is reworked to be more straightforward. While IPv6 is the future of networking, we currently live and work in an IPv4 world, especially on the LAN (as of May 2014, IPv4 still carried more than 96% of Internet traffic worldwide, according to Google ). Setting up a new remote access technology should not require one or more potentially expensive projects before it can be deployed.

There is more configuration required on the firewall when setting up the client to be published.
Is VPN required for telecommuting?
Being able to connect securely to your corporate network from a remote location using a Virtual Private Network (VPN) is important, and it may be required by your job if you are a telecommuter. There are some remote access technologies that are widely used, but some new methods have recently emerged that have the ability to change how we work.
Does IT need to touch each machine?
The IT department does not need to touch each machine that needs remote access. Network administrators can set up granular security policies for specific resources on the corporate network, even down to a single web-based application. Software clients are available for mobile devices such as iPhones and iPads.
Does a firewall include VPN?
When a firewall is purchased, it typically includes plenty of licenses for IPsec VPN connections.

Remote virtual computing, also called terminal emulation, allows a user on one computer, called the client, to control another computer, called the host or server, across a network connection.
Why is private key encryption also known as symmetric encryption?
Private key encryption is also known as symmetric encryption because the same key is used during both the encryption and decryption of the data.
Why do some systems require clients to supply two or more pieces of information to verify their identity?
For greater security, some systems require clients to supply two or more pieces of information to verify their identity.

Long-term Remote Access Could Be the Norm for Some Time
Some knowledge workers are trickling back to their actual offices, but many more are still at home and will be for some time. Global Workplace Analytics estimates that 25-30% of the workforce will still be working from home multiple days a week by the end of 2021.
SASE Provides a Simpler, More Secure, Easily Scalable Solution
Cato’s Secure Access Service Edge (or SASE) platform provides a great alternative to VPN for remote access by many simultaneous workers. The platform offers scalable access, optimized connectivity, and integrated threat prevention that are needed to support continuous large-scale remote access.
SASE Supports WFH in the Short-term and Long-term
While some workers are venturing back to their offices, many more are still working from home—and may work from home permanently. The Cato SASE platform is the ideal way to give them access to their usual network environment without forcing them to go through insecure and inconvenient VPNs.
What are the different types of access control systems?
There are several different types of access control systems like discretionary (DAC), mandatory (MAC), and role-based (RBAC). There are also different kinds of access control software and door-readers, allowing you to decide what best fits your needs.
What are the factors that necessitate an electronic access control system?
Other factors that necessitate an electronic access control system include increased scalability, automated control, and the ability for remote management.
Why is an Access Control System Vital?
While mechanical keys remain the simplest and most popular form of access control, especially among small businesses and private residences, they have countless limitations. Keys are easily lost and are not capable of logging who is entering the property or when, making it impossible to monitor such activities. It’s also impractical to use keys when there is a large number of buildings or rooms that require controlled access.
What is an RFID card?
RFID smart cards consist of a built-in processor making them as efficient as a mini single-purpose computer. Consequently, they provide much greater security and quicker access control. These cards can perform two-way transmission with a reader allowing for significantly better encryption.
What is biometric access control?
Biometric enabled access control systems use unique physical features such as irises and fingerprints to grant access to individuals. These features are stored in the system and are compared at the time of the individual’s entry to authenticate their identity. These readers are on the higher end of the security spectrum and are more expensive as a result.
Why is physical access control important?
Be it a private or a commercial property, the safety of its occupants as well as its assets relies heavily on this one factor. Hence, it is of paramount importance to have an effective physical access control system in place.
Do keypad door readers require a password?
Keypad door readers require a PIN code or a password to gain access. While it is definitely a step-up from a mechanical lock and key, a PIN code keypad is still meant for relatively low-security locations in comparison to its other electronic counterparts. It restricts access to those who know the PIN or passcode but is not equipped with the ability to verify their identity.
